BACKGROUNDS: Cancer continues to be the leading cause of death worldwide, significantly impacting both health and the economy. Natural products have emerged as promising sources for the development of new anticancer drugs, with galangal and their active ingredient, galangin, garnering substantial interest. PURPOSE: This study summarizes recent findings on the anticancer properties of galangal and galangin, highlighting their potential to target various cancer types. METHODS: We systematically searched the literature across PubMed, Web of Science, and Google Scholar, using keywords such as "Alpinia officinarum," "Alpinia galanga", "galangal," and "galangin." This thorough approach allowed us to gather and compile a comprehensive collection of existing research on the topic. RESULTS: This article provided a thorough analysis of the distribution of galangal, the methods used to extract the active compounds of galangal, and the anticancer properties of both galangin and galangal. It is important to note that galangal and galangin primarily function by regulating the signaling pathways of PI3K/Akt, MAPK, AMPK, p53, NF-κB, and Ras/RAF/MEK/ERK, which in turn triggers apoptosis, autophagy, and ROS while preventing the migration and invasion of cancer cells. We also discussed their toxicity, bioavailability, and clinical uses. CONCLUSION: In conclusion, galangal extract and galangin have a lot of promise for treating cancer. It is anticipated that this review will further advance the use of galangal extract and galangin as potential cancer treatment medications. Moreover, the discovery and development of drugs based on galangal has enormous potential for the therapy of cancer.

Therapeutic potential of compound extract from Dracocephalum Rupestre Hance and Berberidis Radix against Salmonella-induced lamb diarrhea.

Lamb diarrhea is primarily induced by bacterial infections, causing great economic and health challenges. Traditional antibiotic treatments raise concerns over drug resistance and environmental contamination. We explored the therapeutic potential of a compound extract from Dracocephalum rupestre Hance and Berberidis Radix against Salmonella-induced diarrhea in lamb. Twenty-five five-week-old Kunming mice (20 ± 5 g) were used. A controlled laboratory experiment, combing histological examinations, serum cytokine level analysis, gut microbiota composition analysis, and short-chain fatty acid quantification were conducted. Results demonstrated significant reparative effects on intestinal mucosal damage of the compound. Compound treatment notably reduced serum levels of inflammatory cytokines (IL-6, IL-8, sigA, and TNF-α), indicating an anti-inflammatory effect. Gene expression analysis of mucosal repair markers (PCNA, TGF, and EGFR) confirmed the positive impacts on intestinal recovery processes after treatment. Microbiota analysis revealed concentration-dependent alterations in gut microbial composition, with a notable increase in beneficial bacterial genera such as Muribaculum and Prevotella, suggesting the role of the compound in promoting gut health. Additionally, short-chain fatty acid analysis indicated an increase in beneficial acids, which are critical for the gut and overall health. This investigation highlights the potential therapeutic benefits of Dracocephalum rupestre Hance combining Berberidis Radix in lamb with Salmonella-induced diarrhea.

Potential Neuroprotective Effects of Alpinia officinarum Hance (Galangal): A Review.

Background/Objectives: This review aims to provide a detailed understanding of the current evidence on Alpinia officinarum Hance (A. officinarum) and its potential therapeutic role in central nervous system (CNS) disorders. CNS disorders encompass a wide range of disorders affecting the brain and spinal cord, leading to various neurological, cognitive and psychiatric impairments. In recent years, natural products have emerged as potential neuroprotective agents for the treatment of CNS disorders due to their outstanding bioactivity and favourable safety profile. One such plant is A. officinarum, also known as lesser galangal, a perennial herb from the Zingiberaceae family. Its phytochemical compounds such as flavonoids and phenols have been documented to have a powerful antioxidants effect, capable of scavenging free radicals and preventing oxidative damage. Methods: In this review, we critically evaluate the in vitro and in vivo studies and examine the mechanisms by which A. officinarum exerts its neuroprotective effect. Results: Several studies have confirmed that A. officinarum exerts its neuroprotective effects by reducing oxidative stress and cell apoptosis, promoting neurite outgrowth, and modulating neurotransmitter levels and signalling pathways. Conclusions: Although previous studies have shown promising results in various models of neurological disorders, the underlying mechanisms of A. officinarum in Alzheimer's (AD) and Parkinson's disease (PD) are still poorly understood. Further studies on brain tissue and cognitive and motor functions in animal models of AD and PD are needed to validate the results observed in in vitro studies. In addition, further clinical studies are needed to confirm the safety and efficacy of A. officinarum in CNS disorders.

Hepatoprotective action mechanism and quantification of soyasaponin Bb in Abri Herba by HPLC and network pharmacology.

ETHNOPHARMACOLOGICAL RELEVANCE: The herb of Abrus cantoniensis Hance (AC) is an important Traditional Chinese Medicine (TCM) and is also used as an herbal tea with hepatoprotective action. Soyasaponin Bb is one of the pharmacodynamic substances of AC for the herb's effective pharmacological activity. This study aims to investigate the anti-fibrotic and hepatoprotective activities of soyasaponin Bb in vivo and in vitro experiments, mechanism by network pharmacology and quantification by HPLC. MATERIALS AND METHODS: High-performance liquid chromatography (HPLC) was applied to evaluate the quality of the herb and determine the contents of soyasaponin Bb from different sources and parts of the AC. In vivo experiments were conducted to induce an acute liver injury model by injecting CCl4 into mice, and an in vitro hepatic fibrosis model was established by cultivating LX-2 cells with TGF-ß1. These models were used to explore the anti-fibrotic and hepatoprotective effects of soyasaponin Bb and its underlying mechanisms. In addition, the potential target genes corresponding to soyasaponin Bb were identified using the Swiss Target Prediction database through network pharmacology methods. Meanwhile, hepatic fibrosis targets were screened using the GeneCards, TTD, and OMIM disease databases. The STING database was used to construct the protein-protein interaction (PPI) network of soyasaponin Bb-hepatic fibrosis. The soyasaponin Bb-hepatic fibrosis disease target-pathway network was constructed using Cytoscape 3.9.1 software. Gene Ontology (GO) and the Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses were performed to enrich and analyze the common targets of the drug and the disease, aiming to identify the potential targets and pathways involved in the anti-fibrotic and hepatoprotective effects of soyasaponin Bb. RESULTS: The content of soyasaponin Bb varied across different sources, with the roots containing the highest concentration, up to 0.2480%. In vivo experiments showed that soyasaponin Bb had a protective effect against CCl4-induced acute liver injury, effectively inhibiting the increase in ALT and AST levels and slowing down the hepatocyte inflammatory damage caused by CCl4. Soyasaponin Bb also down-regulated MDA levels and up-regulated SOD levels, indicating a certain antioxidant capacity. In vitro cell experiments showed that soyasaponin Bb could effectively inhibit the proliferation of HSC-LX2 cells induced by TGF-ß1 by regulating the TGF-ß1/α-SMA pathway, significantly down-regulate the protein expression of TGF-ß1 and α-SMA, while also reducing the levels of inflammatory cytokines IL-6 and IL-1ß. Further network pharmacology analysis suggested that soyasaponin Bb can exert anti-fibrosis activity by regulating the IBD signaling pathway, Th17 signaling pathway, Hepatitis B signaling pathway, and JAK-STAT signaling pathway. CONCLUSION: Soyasaponin Bb is primarily distributed in the root of AC, and it has a strong protective effect against CCl4-induced acute liver injury. It can reduce the level of inflammatory factors, relieve inflammation, and exert anti-fibrotic activity by regulating the TGF-ß1/α-SMA pathway. Its potential anti-hepatic fibrosis mechanism has been investigated through network pharmacology.

Alpinia officinarum Hance extract relieved sepsis-induced myocardial ferroptosis and inflammation by inhibiting lncRNA MIAT/TRAF6/NF-κB axis.

Sepsis is generally triggered by a dysfunctional host response to infection, and it can result in life-threatening organ dysfunction. Alpinia officinarum Hance (AO) exhibits regulatory functions in some diseases. However, whether AO extract (AOE) plays a promoting role in sepsis--triggered myocardial injury is unclear. This study was aimed at investigating the regulatory effects of AOE on myocardial ferroptosis and inflammation in sepsis, and the regulation effects on the lncRNA MIAT/TRAF6/NF-κB axis. Lipopolysaccharide (LPS) was used to treat mice for establishing an in vivo sepsis model. The pathological changes in heart tissues were observed through hematoxylin-eosin (HE) staining. The levels of CK-MB, cTnl, MDA, SOD, IL-1ß, IL-18, IL-6, and TNF-α in serum were detected through enzyme-linked immunosorbent assay (ELISA). The level of Fe2+ was assessed, and the protein expressions (ACSL4, GPX4, TRAF6, p-P65, and P65) were examined through western blot. The expressions of lncRNA MIAT and TRAF6 were measured through real-time quantitative polymerase chain reaction (RT-qPCR). Our results demonstrated that AOE treatment ameliorated sepsis-triggered myocardial damage by reducing the disordered cardiomyocytes, the destroyed sarcolemma, and the CK-MB and cTnl levels. In addition, AOE treatment inhibited sepsis-induced myocardial ferroptosis and inflammation by regulating Fe2+, ACSL4, GPX4, IL-1ß, IL-18, IL-6, and TNF-α levels. Moreover, the improvement effect of AOE was strengthened with the increase in the dose of AOE (25, 50, 100 mg/kg). It was also revealed that AOE treatment retarded the lncRNA MIAT/TRAF6/NF-κB axis. Rescue assays manifested that overexpression of MIAT reduced the cardioprotective effect of AOE. In conclusion, AOE relieved sepsis-induced myocardial ferroptosis and inflammation by inhibiting lncRNA MIAT/TRAF6/NF-κB axis. These findings may provide a potential therapeutic drug for the treatment of sepsis.

Discrimination of Abrus cantoniensis Hance and Abrus mollis Hance using UPLC-Q/TOF-MS and assessment of their in vivo hepatoprotective effects.

ETHNOPHARMACOLOGICAL RELEVANCE: In Guangzhou and Guangxi, China, Abrus cantoniensis Hance (AH) is known for its liver-protective properties and is commonly used in herbal teas and soups. In the herbal market and pharmaceutical preparations, AH and Abrus mollis Hance (AMH) are often used interchangeable. Despite their morphological and usage similarities, distinguishing their differences is essential for scientific research and clinical practice. AIM OF THE STUDY: This study focuses on the morphological identification, chemical composition, and hepatoprotective effectiveness of AH and AMH. It aims to evaluate their interchangeable use and provide a rationale for this practice. This research helps regulate the market of AH medicinal materials, ensuring clinical safety and effectiveness. MATERIALS AND METHODS: Samples of AH and AMH roots, stems, leaves, and seeds were collected and photographed using a stereoscope and digital imaging system. The chemical components of AH and AMH were qualitatively analyzed using UPLC-Q/TOF-MS. Chemometric techniques, such as PCA and OPLS-DA, were employed to discern the componential differences between the two species. A CCl4-induced acute liver injury mouse model was developed to assess hepatoprotective effects. The hepatoprotective properties of AH and AMH were evaluated by analyzing the liver index, H&E staining, changes in serum liver function indicators (TBIL, ALT, AST), and concentrations of SOD, MDA in liver homogenate. RESULTS: The root color, texture, stem diameter, cross-sectional characteristics, leaf shape, and seed morphology of the two plants were observed. Notable differences were identified, which can be used for accurate identification. The UPLC-Q/TOF-MS identified 50 compounds in both species, which were classified into 3 alkaloids, 22 flavonoids, 2 triterpenes, 10 triterpene saponins, 10 amides, and 3 others, and 20 different compounds between AH and AMH were screened by chemometrics. By improving serum biomarkers (ALT, AST, TBIL) and regulating oxidative stress markers (SOD, MDA), the alleviating effect of AH and AMH extracts on liver injury was confirmed. Notably, AH showed a stronger liver protective effect, significantly reducing ALT and AST levels more than AMH. CONCLUSION: This study enhances understanding of the morphological identification, chemical profiling, and hepatoprotective effects of AH and AMH. It provides a reference for future scientific research and the clinical application of AH in treating liver damage.

Sugar Transporter HmSWEET8 Cooperates with HmSTP1 to Enhance Powdery Mildew Susceptibility in Heracleum moellendorffii Hance.

The powdery mildew caused by Eeysiphe heraclei is a serious concern in Heracleum moellendorffii Hance. Therefore, exploring the mechanisms underlying sugar efflux from host cells to the fungus during the plant-fungus interaction showed great significance. The study successfully cloned HmSWEET8 and HmSTP1 genes based on RNA-seq technology. The complementation assays in yeast EBY.VW4000 found HmSWEET8 and HmSTP1 transporting hexose. Over-expressing or silencing HmSWEET8 in H. moellendorffii leaves increased or decreased powdery mildew susceptibility by changing glucose concentration in infective sites. Meanwhile, over-expressing HmSTP1 in H. moellendorffii leaves also increased powdery mildew susceptibility by elevating the glucose content of infective areas. Additionally, HmSTP1 expression was up-regulated obviously in HmSWEET8 over-expressed plants and inhibited significantly in HmSWEET8 silenced plants. Co-expressing HmSWEET8 and HmSTP1 genes significantly increased powdery mildew susceptibility compared with over-expressed HmSWEET8 or HmSTP1 plants alone. The results demonstrated that HmSTP1 may assist with HmSWEET8 to promote E. heraclei infection. Consequently, the infection caused by E. heraclei resulted in the activation of HmSWEET8, leading to an increased transfer of glucose to the apoplasmic spaces at the sites of infection, then, HmSTP1 facilitated the transport of glucose into host cells, promoting powdery mildew infection.

Protective Effects and Mechanism of Heracleum moellendorffii Hance on Alcohol-Induced Cognitive Decline in Mice.

Chronic and continuous alcohol consumption increases the risk of cognitive decline and may lead to alcohol-related dementia. We investigated the potential of Heracleum moellendorffii Hance root extract (HME) for treating alcohol-related cognitive impairment. Behavioral tests evaluated the effects of HME on cognitive function and depression. Changes in hippocampus and liver tissues were evaluated by Western blotting and H&E staining. The group treated with HME 200 mg/kg showed a significant increase in spontaneous alternation in Y-maze and a decrease in immobility in a forced swimming test (FST) compared to the vehicle-treated group. These results suggest that HME can restore memory deficits and reverse depressive symptoms caused by chronic alcohol consumption. The HME-treated group also upregulated brain-derived neurotrophic factor (BDNF), phosphorylated extracellular signal-regulated kinase 1/2 (ERK1/2), and phosphorylated cAMP response element-binding protein (CREB) in the hippocampus. Additionally, it reduced lipid vacuolation in the liver and increased the expression of aldehyde dehydrogenase 1 (ADH1). The administration of HME improves cognitive impairment and reverses depressive symptoms due to alcohol consumption, restoring neural plasticity in the hippocampus and alcohol metabolism in the liver. These findings suggest that HME is a promising treatment for alcohol-related brain disorders. Molecular mechanisms underlying the therapeutic effects of HME and its active ingredients should be investigated further.

Contribution of plant growth-promoting endophytic bacteria from hyperaccumulator to non-host plant zinc nutrition and health.

Application of microbial agents is a novel strategy to improve the quality and health of plant, which can be used to increase zinc (Zn) uptake and alleviate Zn toxicity. Here, endophytic bacteria with Zn solubilizing and growth-promoting properties were isolated from hyperaccumulating ecotype (HE) of Sedum alfredii Hance and their effects on Zn absorption and accumulation of non-hyperaccumulating ecotype (NHE) were studied. The results showed that most endophytic bacteria of HE have good Zn solubilizing or growth-promoting properties. Under the condition of 20 µM ZnSO4, the biomass of NHE inoculated with SaPS1, SaEN2, SaPR2, SaBA2, SaBA3 was 2.8-3.2 times higher than that of non-inoculation control, and the Zn concentration of shoots was increased by 45.9, 89.0, 53.7, 77.5, and 42.6% after inoculation with SaPA1, SaP1, SaEN2, SaBA1, and SaBA2. Under the condition of 100 µM ZnSO4, inoculation with SaVA1, SaPS3, SaB1, SaPR1, and SaEN3 alleviated Zn stress and significantly reduced Zn concentration of shoots. Therefore, endophytic bacteria can be an effective means of improving plant Zn nutrition quality in the normal condition and benefit plant health in the stress environment.

In this study, endophytes with Zn solubilizing properties were systematically isolated from Zn hyperaccumulator Sedum alfredii Hance. The aim is to identify endophyte resources with good promoting effect on plant growth and Zn uptake, and to provide scientific basis for the development of efficient biofortified agent.

Effect of AC electric field on enhancing phytoremediation of Cd-contaminated soils in different pH soils.

To increase the efficiency of phytoremediation to clean up heavy metals in soil, assisted with alternating current (AC) electric field technology is a promising choice. Our experiments utilized the hyperaccumulator Sedum alfredii Hance and the fast-growing, high-biomass willow (Salix sp.). We investigated the efficiency of AC field combined with S. alfredii-willow intercropping for removing Cd from soils with different pH values. In the AC electric field treatment with S. alfredii-willow intercropping, the available Cd content in acidic soil increased by 50.00% compared to the control, and in alkaline soil, the increase was 100.00%. Furthermore, AC electric field promoted Cd uptake by plants in both acidic and alkaline soils, with Cd accumulation in the aboveground increased by 20.52% (P < 0.05) and 11.73%, respectively. In conclusion, the integration of AC electric fields with phytoremediation demonstrates significant favorable effectiveness.

The Flavonoid Glycoside from Abrus cantoniensis Hance Alleviates Alcoholic Liver Injury by Inhibiting Ferroptosis in an AMPK-Dependent Manner.

Abrus cantoniensis Hance is a vegetative food and can be used as a folk beverage or soup to clear liver toxins and prevent liver damage. However, the components and effects of A. cantoniensis Hance in alcohol-induced liver injury were unknown. This study aimed to obtain abundant phytochemicals from A. cantoniensis Hance and identify the potency of the isolates in preventing alcohol-induced liver injury. Alcohol-stimulated AML12 cells and Lieber-DeCarli diet-fed mice were used to establish in vitro and in vivo models, respectively. Our findings indicated that flavonoid glycosides, especially AH-15, could significantly alleviate alcohol-induced liver injury by inhibiting oxidative stress. Furthermore, we demonstrated that AH-15 inhibited ferroptosis induced by lipid peroxidation. Mechanically, we found that AH-15 regulated nuclear factor erythroid 2-related factor 2 (NRF2) expression via activation of AMP-activated protein kinase (AMPK) signaling. These results indicate that A. cantoniensis Hance is a great potential functional food for alleviating alcohol-induced liver injury.

Effects of soil moisture and an AC-electric field on the phytoremediation of the Cd-contaminated soil.

Phytoremediation enhanced by electric field has been considered a green and low-cost technology for remediating heavy metal-contaminated soils. Soil moisture is a main environmental factor that affects Cd availability in the soil. However, the effects of soil moisture and AC-electric field on the remediation efficiency of willow (Salix spp.) and S. Alfredii interplanted together remain unclear. In the present study, we designed four treatments (60% soil field capacity, 60% soil field capacity + 0.5 V·cm-1 AC, 100% soil field capacity, 100% soil field capacity + 0.5 V·cm-1 AC) to explore the impacts of soil moisture and AC-electric field on soil Cd availability and Cd accumulation in plants. The results showed that the application of an AC-electric field significantly increased soil Cd availability by 20.9% and 10.8% under both 60% and 100% soil field capacity, respectively. Both high water with and without AC-electric field treatments reduced the proportion of acid-extractable and reducible Cd of soil but increased the proportion of residual Cd. Compared with the control, an AC-electric field with 60% soil field capacity significantly enhanced the biomass of S. Alfredii shoots by 31.2% and increased Cd accumulation in willow leaves and S. Alfredii shoots by 14.6% and 32.3%, respectively. In addition, the biomass production of willow was significantly enhanced but the uptake of Cd by willow was dramatically decreased under an AC-electric field with high water treatment. Therefore, these results suggest that the AC-electric field combined with 60% soil field capacity may be a more promising remediation technique to clean up the Cd-contaminated soil.

The Use of Polysaccharide AOP30 from the Rhizome of Alpinia officinarum Hance to Alleviate Lipopolysaccharide-Induced Intestinal Epithelial Barrier Dysfunction and Inflammation via the TLR4/NfκB Signaling Pathway in Caco-2 Cell Monolayers.

Alpinia officinarum Hance is rich in carbohydrates and is flavored by natives. The polysaccharide fraction 30 is purified from the rhizome of A. officinarum Hance (AOP30) and shows excellent immunoregulatory ability when administered to regulate immunity. However, the effect of AOP30 on the intestinal epithelial barrier is not well understood. Therefore, the aim of this study is to investigate the protective effect of AOP30 on the intestinal epithelial barrier using a lipopolysaccharide (LPS)-induced intestinal epithelial barrier dysfunction model and further explore its underlying mechanisms. Cytotoxicity, transepithelial electrical resistance (TEER) values, and Fluorescein isothiocyanate (FITC)-dextran flux are measured. Simultaneously, the protein and mRNA levels of tight junction (TJ) proteins, including zonula occludens-1 (ZO-1), Occludin, and Claudin-1, are determined using Western blotting and reverse-transcription quantitative polymerase chain reaction methods, respectively. The results indicate that AOP30 restores the LPS-induced decrease in the TEER value and cell viability. Furthermore, it increases the mRNA and protein expression of ZO-1, Occludin, and Claudin-1. Notably, ZO-1 is the primary tight junction protein altered in response to LPS-induced intestinal epithelial dysfunction. Additionally, AOP30 downregulates the production of TNFα via the Toll-like receptor 4 (TLR4)/NF-κB signaling pathway. Collectively, the findings of this study indicate that AOP30 can be developed as a functional food ingredient or natural therapeutic agent for addressing intestinal epithelial barrier dysfunction. It sheds light on the role of AOP30 in improving intestinal epithelial function.

Abrus cantoniensis Hance: Ethnopharmacology, phytochemistry and pharmacology of a promising traditional Chinese medicine.

ETHNOPHARMACOLOGICAL RELEVANCE: Abrus cantoniensis Hance (ACH), known as Jigucao (Chinese: ) has been used in ethnopharmacology for a long history with therapeutic effects for clearing heat, soothing the liver, especially in treating acute and chronic hepatitis which was very effective. In southern China, such as Guangdong and Guangxi, people often use ACH in soup or herbal tea as dietetic therapy. AIM OF THE REVIEW: This paper aims to review ACH's ethnopharmacology, phytochemistry, and pharmacological activity systematically, at the same time, we also hope to provide more research avenues between traditional uses and pharmacological properties. MATERIAL AND METHODS: Through PubMed, Wan Fang Database, CNKI, Web of Science, EBSCO Database, and Google Scholar search for relevant literature in both Chinese and English, the keywords "Abrus cantoniensis, Abrus cantoniensis Hance, Jigucao, pharmacology, chemical constituents, clinical application, network pharmacology" were used alone or combination. RESULTS: Traditionally, ACH was believed to have the effect of soothing the liver, clearing heat, and detoxifying, often used to treat diseases of the liver and inflammation. Modern pharmacological research indicates that ACH has liver protection, anti-inflammation, anti-oxidant, immunomodulation, anti-tumor effects and so on. Whether it was a single chemical compound or an extract from ACH, studies have found that it has abundant pharmacological activities, these were the fundamental sources of traditional uses, like liver protection and anti-inflammation. CONCLUSIONS: A systematic review found that modern phytochemistry and pharmacodynamic research reports on ACH are closely related to its traditional uses, especially its hepatoprotective and anti-inflammatory effects. Modern research has also further explored and expanded the effects of ACH, such as its anti-tumor effect. And all these efforts are gradually filling the gap between traditional uses and modern pharmacology. In general, the current research on the pharmacodynamic mechanism of ACH still needs further in-depth research, and the strategies adopted must also be further strengthened.

Structurally diverse diterpenoids from the seeds of Caesalpinia minax Hance and their bioactivities.

Eight previously undescribed diterpenoids, caesamins A-H (1-8), were separated and identified from the seeds of Caesalpinia minax Hance. Their structures were characterized by extensive spectroscopic data and X-ray crystallographic analysis. Structurally, caesamin A (1) is the first cassane-type diterpenoid with a C23 carbon skeleton containing an unusual isopropyl. Caesamin F (6) represents the first example of cleistanthane diterpenoid from the genus Caesalpinia. Caesamins B (2) and F (6) exhibited inhibitory activity against LPS-induced nitric oxide production in RAW 264.7 macrophages with IC50 values of 45.67 ± 0.92 and 42.99 ± 0.24 µM, comparable to positive control 43.69 ± 2.62 µM of NG-Monomethyl-L-arginine. Furthermore, the chemotaxonomic significance of the isolates was discussed.

The Impact of Ulmus macrocarpa Extracts on a Model of Sarcopenia-Induced C57BL/6 Mice.

Aging leads to tissue and cellular changes, often driven by oxidative stress and inflammation, which contribute to age-related diseases. Our research focuses on harnessing the potent anti-inflammatory and antioxidant properties of Korean Ulmus macrocarpa Hance, a traditional herbal remedy, to address muscle loss and atrophy. We evaluated the effects of Ulmus extract on various parameters in a muscle atrophy model, including weight, exercise performance, grip strength, body composition, muscle mass, and fiber characteristics. Additionally, we conducted Western blot and RT-PCR analyses to examine muscle protein regulation, apoptosis factors, inflammation, and antioxidants. In a dexamethasone-induced muscle atrophy model, Ulmus extract administration promoted genes related to muscle formation while reducing those associated with muscle atrophy. It also mitigated inflammation and boosted muscle antioxidants, indicating a potential improvement in muscle atrophy. These findings highlight the promise of Ulmus extract for developing pharmaceuticals and supplements to combat muscle loss and atrophy, paving the way for clinical applications.

Combined metabolome and transcriptome reveal HmF6'H1 regulating simple coumarin accumulation against powdery mildew infection in Heracleum moellendorffii Hance.

BACKGROUND: Powdery mildew, caused by Eeysiphe heraclei, seriously threatens Heracleum moellendorffii Hance. Plant secondary metabolites are essential to many activities and are necessary for defense against biotic stress. In order to clarify the functions of these metabolites in response to the pathogen, our work concentrated on the variations in the accumulation of secondary metabolites in H. moellendorffii during E. heraclei infection. RESULTS: Following E. heraclei infection, a significant upregulation of coumarin metabolites-particularly simple coumarins and associated genes was detected by RNA-seq and UPLC-MS/MS association analysis. Identifying HmF6'H1, a Feruloyl CoA 6'-hydroxylase pivotal in the biosynthesis of the coumarin basic skeleton through ortho-hydroxylation, was a significant outcome. The cytoplasmic HmF6'H1 protein was shown to be able to catalyze the ortho-hydroxylation of p-coumaroyl-CoA and caffeoyl-CoA, resulting in the formation of umbelliferone and esculetin, respectively. Over-expression of the HmF6'H1 gene resulted in increased levels of simple coumarins, inhibiting the biosynthesis of furanocoumarins and pyranocoumarins by suppressing PT gene expression, enhancing H. moellendorffii resistance to powdery mildew. CONCLUSIONS: These results established HmF6'H1 as a resistance gene aiding H. moellendorffii in combatting E. heraclei infection, offering additional evidence of feruloyl-CoA 6'-hydroxylase role in catalyzing various types of simple coumarins. Therefore, this work contributes to our understanding of the function of simple coumarins in plants' defense against powdery mildew infection.

Comparisons of pharmacokinetics and tissue distribution of six major bioactive components of the herbal pair Alpinia officinarum-Cyperus rotundus in normal and primary dysmenorrhea rats.

The Liangfu formula, as described in 'Liangfang Jiye', is well-known for its efficacy in treating stomach pain, abdominal pain, and dysmenorrhea. This research aimed to investigate the pharmacokinetics and tissue distribution of 5-hydroxy-7-(4-hydroxy-3-methoxyphenyl)-1-phenyl-3-heptanone (DPHA), Galangin, Kaempferide, 5-Hydroxy-1,7-diphenyl-3-heptanone (DPHC), α-Cyperone, and Nootkatone in vivo using an LC-MS/MS method. The method successfully separated the six active components and internal standards (Chrysin and Yakuchinone-A) on an XB-C18 column with a mobile phase of 0.2 ‰ formic acid water-acetonitrile. It demonstrated good linearity with a correlation coefficient (r2) ≥ 0.9911 and a lower limit of quantification (LLOQ) of 5-80 ng/mL for the different components. Precision, accuracy, matrix effects, and recovery rates were within acceptable ranges. Pharmacokinetic analysis revealed significant differences in parameters between primary dysmenorrhea (PD) and normal rats (especially AUC, Tmax, and CLz/F). Tissue distribution showed that the six active components of the herbal pair Alpinia officinarum Hance-Cyperus rotundus L. (HPAC) extract was primarily distributed in the liver, lung, and kidney. This study offers valuable insights into the potential mechanisms of action and drug development for treating PD.

Kaempferol from Alpinia officinarum hance induces G2/M cell cycle arrest in hepatocellular carcinoma cells by regulating the ATM/CHEK2/KNL1 pathway.

ETHNOPHARMACOLOGICAL RELEVANCE: Alpinia officinarum Hance (A. officinarum), a perennial herb known for its medicinal properties, has been used to treat various ailments, such as stomach pain, abdominal pain, emesis, and digestive system cancers. A. officinarum is extensively cultivated in the Qiongzhong and Baisha regions of Hainan, and it holds substantial therapeutic value for the local Li people of Hainan. Kaempferol, a flavonoid derived from A. officinarum, has demonstrated anticancer properties in various experimental and biological studies. Nevertheless, the precise mechanisms through which it exerts its anti-hepatocellular carcinoma (HCC) effects remain to be comprehensively delineated. AIM OF THE STUDY: This investigation aims to elucidate the anti-HCC effects of kaempferol derived from A. officinarum and to delve into its underlying mechanistic pathways. MATERIALS AND METHODS: Using ultra-high performance liquid chromatography-mass spectrometry/mass spectrometry (UPLC-MS/MS) to identify active compounds in A. officinarum. HCCLM3 and Huh7 cells were used to study the anti-HCC effect of kaempferol from A. officinarum. The cytotoxicity and proliferation of kaempferol and A. officinarum were measured using CCK-8 and EDU staining. Wound-healing assays and three-dimensional tumor spheroid models were further used to evaluate migration and the anti-HCC activity of kaempferol. The cell cycle and apoptosis were evaluated by flow cytometry. Western blot and qRT-PCR were used to detect the expression of proteins and genes associated with the cell cycle checkpoints. Finally, bioinformatics was used to analyze the relationship between the differential expression of core targets in the ATM/CHEK2/KNL1 pathway and a poor prognosis in clinical HCC samples. RESULTS: UPLC-MS/MS was employed to detect five active compounds in A. officinarum, such as kaempferol. The CCK-8 and EDU assays showed that kaempferol and A. officinarum significantly inhibited the proliferation of HCC cells. A wound-healing assay revealed that kaempferol remarkably inhibited the migration of HCC cells. Kaempferol significantly suppressed the growth of tumor spheroids. In addition, kaempferol markedly induced G2/M arrest and promoted apoptosis of HCC cells. Mechanically, kaempferol significantly reduced the protein and mRNA expression levels of ATM, CHEK2, CDC25C, CDK1, CCNB1, MPS1, KNL1, and Bub1. Additionally, the combination of kaempferol and the ATM inhibitor KU55933 had a more significant anti-HCC effect. The results of bioinformatics showed that ATM, CHEK2, CDC25C, CDK1, and KNL1 were highly expressed in patients with HCC and cancer tissues, indicating that these genes have certain value in the clinical diagnosis of HCC. CONCLUSIONS: Collectively, our results revealed that kaempferol from A. officinarum inhibits the cell cycle by regulating the ATM/CHEK2/KNL1 pathway in HCC cells. In summary, our research presents an innovative supplementary strategy for HCC treatment.
