Ginger essential oil prevents NASH progression by blocking the NLRP3 inflammasome and remodeling the gut microbiota-LPS-TLR4 pathway in mice.

BACKGROUND: Diet and gut microbiota contribute to non-alcoholic steatohepatitis (NASH) progression. High-fat diets (HFDs) change gut microbiota compositions, induce gut dysbiosis, and intestinal barrier leakage, which facilitates portal influx of pathogen-associated molecular patterns including lipopolysaccharides (LPS) to the liver and triggers inflammation in NASH. Current therapeutic drugs for NASH have adverse side effects; however, several foods and herbs that exhibit hepatoprotection could be an alternative method to prevent NASH. METHODS: We investigated ginger essential oil (GEO) against palm oil-containing HFDs in LPS-injected murine NASH model. RESULTS: GEO reduced plasma alanine aminotransferase levels and hepatic pro-inflammatory cytokine levels; and increased antioxidant catalase, glutathione reductase, and glutathione levels to prevent NASH. GEO alleviated hepatic inflammation through mediated NLR family pyrin domain-containing 3 (NLRP3) inflammasome and LPS/Toll-like receptor four (TLR4) signaling pathways. GEO further increased beneficial bacterial abundance and reduced NASH-associated bacterial abundance. CONCLUSION: This study demonstrated that GEO prevents NASH progression which is probably associated with the alterations of gut microbiota and inhibition of the LPS/TLR4/NF-κB pathway. Hence, GEO may offer a promising application as a dietary supplement for the prevention of NASH.

The "root" causes behind the anti-inflammatory actions of ginger compounds in immune cells.

Ginger (Zingiber officinale) is one of the most well-known spices and medicinal plants worldwide that has been used since ancient times to treat a plethora of diseases including cold, gastrointestinal complaints, nausea, and migraine. Beyond that, a growing body of literature demonstrates that ginger exhibits anti-inflammatory, antioxidant, anti-cancer and neuroprotective actions as well. The beneficial effects of ginger can be attributed to the biologically active compounds of its rhizome such as gingerols, shogaols, zingerone and paradols. Among these compounds, gingerols are the most abundant in fresh roots, and shogaols are the major phenolic compounds of dried ginger. Over the last two decades numerous in vitro and in vivo studies demonstrated that the major ginger phenolics are able to influence the function of various immune cells including macrophages, neutrophils, dendritic cells and T cells. Although the mechanism of action of these compounds is not fully elucidated yet, some studies provide a mechanistic insight into their anti-inflammatory effects by showing that ginger constituents are able to target multiple signaling pathways. In the first part of this review, we summarized the current literature about the immunomodulatory actions of the major ginger compounds, and in the second part, we focused on the possible molecular mechanisms that may underlie their anti-inflammatory effects.

OBJECTIVES: To observe the efficacy and safety of ginger-partitioned moxibustion combined with ringheaded thumb-tack needle stimulation in the prevention and treatment of chemotherapy-induced nausea and vomiting (CINV) in patients with malignant tumors. METHODS: Patients with malignant tumors and suffering from chemotherapy were randomly divided into control group (35 cases, 4 cases dropped off) and observation group (35 cases, 2 cases dropped off). The patients of the control group were treated by orally taking ondansetron hydrochloride tablets 8 mg/time, 3 times a day for 3 d, and those of the observation group treated by ginger-partitioned moxibustion combined with ringheaded thumb-tack needle stimulation of Zusanli(ST36), Neiguan(PC6), Tianshu(ST25), Zhongwan(CV12) and Guanyuan(CV4) once a day for a total of 3 d, based on the treatment of the control group. The patients' gastrointestinal reaction degree after the 1st , 2nd and the 3rd day of treatment were recorded. The Karnofsky performance status (KPS) score (0-100 points) was used for assessing the patients' quality of life. The TCM syndrome score (4 grades：no, mild, medium and severe, i.e. 0, 2, 4 and 6 points) was given according to the patients' severity of symptoms of spleen (stomach) qi deficiency (nausea and vomiting, abdominal distension after eating, belching, loss of appetite, weakness and laziness to speak, fatigue, and loose stool). The safety of the treatment was assessed by examining the patients' blood routine, liver function and kidney function, and the adverse reactions including blisters, allergies, burns and fainting during acupuncture treatment. RESULTS: After the 2nd and 3rd day of treatment, the patients conditions of vomiting and nausea in the observation group were significantly better than those of the control group (P<0.05). The TCM syndrome score and KPS score were significantly decreased in comparison with those of pre-treatment in both groups (P<0.05), and the TCM syndrome score was obviously lower in the observation group than in the control group (P<0.05). No significant differences were found between the two groups in the KPS score after the treatment , and in the levels of white blood cells (WBC), hemoglobin (HGB), platelets (PLT), absolute neutrophil count (ANC), alanine transaminase (ALT), aspartate aminotransferase (AST), creatinine(Cr), and blood urea nitrogen (BUN). CONCLUSIONS: The use of ginger-partitioned moxibustion combined with ringheaded thumb-tack needle stimulation is safe for CINV patients, and can effectively relieve nausea and vomiting and alleviate digestive symptoms.

[In dustrial development status and strategy of improving quality and efficiency of ginger, a resource for both medicine and food use].

China cultivates characteristic resource plant Zingiber officinale for both medicine and food use, with a long history of cultivation, production, and application. With the continuous excavation of the health and skin care values of ginger products due to scientific and technological progress, the scale expansion and quality improvement of the ginger industry have been effectively promoted, forming an industrial cluster with rich germplasm resources and diverse product categories represented by the north and south regions of China, and China has been developed as the biggest producer and exporter of raw materials and processed products of ginger.The present situation of ginger germplasm resources, ginger production, market price, and quality control of ginger products was reviewed in this paper.

Insights into the microbial assembly and metabolites associated with ginger (Zingiber officinale L. Roscoe) microbial niches and agricultural environments.

Ginger, a vegetable export from China, is well-known for its spicy flavour and use in traditional Chinese medicine. By examining the interactions of ginger plants' microbiome and metabolome, we can gain insights to advance agriculture, the environment, and other fields. Our study used metataxonomic analysis to investigate ginger plants' prokaryotic and fungal microbiomes in open fields and greenhouses. We also conducted untargeted metabolomic analysis to identify specific metabolites closely associated with ginger microbiome assembly under both agricultural conditions. Various bacteria and fungi were classified as generalists or specialists based on their ability to thrive in different environments and microbial niches. Our results indicate that ginger plants grown in greenhouses have a greater prokaryotic diversity, while those grown in open fields exhibit a greater fungal diversity. We have identified specific co-occurring prokaryotic and fungal genera associated with ginger plant agroecosystems that can enhance the health and growth of ginger plants while maintaining a healthy environment. In the open field these genera include Sphingomonas, Methylobacterium-Methylorubrum, Bacillus, Acidovorax, Rhizobium, Microbacterium, unclassified_f_Comamonadaceae, Herbaspirillum, Klebsiella, Enterobacter, Chryseobacterium, Nocardioides, Subgroup_10, Enterococcus, Pseudomonas, Devosia, g_unclassified_f_Chaetomiaceae, Pseudaleuria, Mortierella, Cheilymenia, and Pseudogymnoascus. In the greenhouse, the enriched genera were Rhizobium, Stenotrophomonas, Aureimonas, Bacillus, Nocardioides, Pseudomonas, Enterobacter, Delftia, Trichoderma, Mortierella, Cheilymenia, Schizothecium, and Actinomucor. Our research has identified several previously unknown microbial genera for ginger plant agroecosystems. Furthermore, our study has important implications for understanding the correlation between ginger's microbiome and metabolome profiles in diverse environments and may pave the way for future research. Specific microbial genera in crop production environments are associated with essential metabolites, including Safingol, Docosatrienoic acid, P-acetaminophen, and Hypoglycin B.

Ginger Extract and Omega-3 Fatty Acids Supplementation: A Promising Strategy to Improve Diabetic Cardiomyopathy.

Diabetic cardiomyopathy may result from the overproduction of ROS, TRPM2 and TRPV2. Moreover, the therapeutic role of ginger, omega-3 fatty acids, and their combinations on the expression of TRPM2 and TRPV2 and their relationship with apoptosis, inflammation, and oxidative damage in heart tissue of rats with type 2 diabetes have not yet been determined. Therefore, this study aimed to investigate the therapeutic effects of ginger and omega-3 fatty acids on diabetic cardiomyopathy by evaluating the cardiac gene expression of TRPM2 and TRPV2, oxidative damage, inflammation, and apoptosis in male rats. Ninety adult male Wistar rats were equally divided into nine control, diabetes, and treated diabetes groups. Ginger extract (100 mg/kg) and omega-3 fatty acids (50, 100, and 150 mg/kg) were orally administrated in diabetic rats for 6 weeks. Type 2 diabetes was induced by feeding a high-fat diet and a single dose of STZ (40 mg/kg). Glucose, cardiac troponin I (cTnI), lipid profile, insulin in serum, and TNF-alpha IL-6, SOD, MDA, and CAT in the left ventricle of the heart were measured. The cardiac expression of TRPM2, TRPV2, NF-kappaB, Bcl2, Bax, Cas-3, and Nrf-2 genes was also measured in the left ventricle of the heart. An electrocardiogram (ECG) was continuously recorded to monitor arrhythmia at the end of the course. The serum levels of cTnI, glucose, insulin, and lipid profile, and the cardiac levels of MDA, IL-6, and TNF-alpha increased in the diabetic group compared to the control group (p<0.05). Moreover, the cardiac levels of SOD and CAT decreased in the diabetic group compared to the control group (p<0.05). The cardiac expression of TRPM2, TRPV2, NF-kappaB, Bax, and Cas-3 increased and Bcl2 and Nrf-2 expression decreased in the diabetic group compared to the control group (p<0.05). However, simultaneous and separate treatment with ginger extract and omega-3 fatty acids (50, 100, and 150 mg/kg) could significantly moderate these changes (p<0.05). The results also showed that the simultaneous treatment of ginger extract and different doses of omega-3 fatty acids have improved therapeutic effects than their individual treatments (p<0.05). It can be concluded that ginger and omega-3 fatty acids showed protective effects against diabetic cardiomyopathy by inhibiting inflammation, apoptosis and oxidative damage of the heart and reducing blood glucose and cardiac expression of TRPM2 and TRPV2. Combining ginger and omega-3 in the diet may provide a natural approach to reducing the risk or progression of diabetic cardiomyopathy while preserving heart structure and function.

Effects of dietary ginger (Zingiber officinale) polysaccharide on the growth, antioxidant, immunity response, intestinal microbiota, and disease resistance to Aeromonas hydrophila in crucian carp (Carassius auratus).

Ginger polysaccharides (GP) promote growth and development in fish. However, the effects of GP on crucian carp remain unclear. The present study investigated the effects of GP on the growth performance, immunity, intestinal microbiota, and disease resistance in crucian carp. Four treatment groups were established with different concentrations of GP (0.1 %, 0.2 %, 0.4 %, and 0.8 %). GP was not added as the control group, and the feeding period lasted for 56 d, followed by a 96-h anti-infection treatment using Aeromonas hydrophila. The results showed that dietary GP significantly improved growth performance, especially in the 0.4 % GP group. Furthermore, GP administration notably increased serum lysozyme (LMZ) activity, digestive enzyme performance, and antioxidant capacity of crucian carp. Moreover, dietary inclusion of GP up-regulated the expression of tumour necrosis factor-α (TNF-α), interleukin-8 (IL-8), interferon-γ (IFN-γ), and nuclear factor kappa-B (NF-κB) genes while down-regulating IL-10 and transforming growth factor-ß (TGF-ß) gene expressions, thus promoting liver health in crucian carp. Additionally, incorporating GP into the diet regulated both the diversity and composition of the intestinal microbiota in crucian carp, explicitly enhancing the relative abundance of beneficial bacteria, such as Fusobacteriota and Firmicutes. Therefore, GP reduces the mortality of crucian carp infected with A. hydrophila. In conclusion, this study provides novel insights into the application of dietary GP in cultured fish and evaluates the value of traditional Chinese medicinal polysaccharides against pathogenic bacteria.

Exploring gingerol glucosides with enhanced anti-inflammatory activity through a newly identified α-glucosidase (ArG) from Agrobacterium radiobacter DSM 30147.

Gingerols are phenolic biomedical compounds found in ginger (Zingiber officinale) whose low aqueous solubility limits their medical application. To improve their solubility and produce novel glucosides, an α-glucosidase (glycoside hydrolase) from Agrobacterium radiobacter DSM 30147 (ArG) was subcloned, expressed, purified, and then confirmed to have additional α-glycosyltransferase activity. After optimization, the ArG could glycosylate gingerols into three mono-glucosides based on the length of their acyl side chains. Compound 1 yielded 63.0 %, compound 2 yielded 26.9 %, and compound 3 yielded 4.37 %. The production yield of the gingerol glucosides optimally increased in 50 mM phosphate buffer (pH 6) with 50 % (w/v) maltose and 1000 mM Li+ at 40 °C for an 24-h incubation. The structures of purified compound 1 and compound 2 were determined as 6-gingerol-5-O-α-glucoside (1) and novel 8-gingerol-5-O-α-glucoside (2), respectively, using nucleic magnetic resonance and mass spectral analyses. The aqueous solubility of the gingerol glucosides was greatly improved. Further assays showed that, unusually, 6-gingerol-5-O-α-glucoside had 10-fold higher anti-inflammatory activity (IC50 value of 15.3 ± 0.5 µM) than 6-gingerol, while the novel 8-gingerol-5-O-α-glucoside retained 42.7 % activity (IC50 value of 106 ± 4 µM) compared with 8-gingerol. The new α-glucosidase (ArG) was confirmed to have acidic α-glycosyltransferase activity and could be applied in the production of α-glycosyl derivatives. The 6-gingerol-5-O-α-glucoside can be applied as a clinical drug for anti-inflammatory activity.

The Effect of Therapeutic Doses of Culinary Spices in Metabolic Syndrome: A Randomized Controlled Trial.

Non-communicable diseases (NCDs) place a significant burden on global health and the healthcare systems which support it. Metabolic syndrome is a major risk factor for a large number of NCDs; however, treatments remain limited. Previous research has shown the protective benefits of edible dietary spices on key components of metabolic syndrome. Therefore we performed a 12-week double-blind, placebo-controlled, randomized, clinical trial to evaluate the effect of ginger (Zingiber officinale), cinnamon (Cinnamomum), and black seed (Nigella sativa) consumption on blood glucose, lipid profiles, and body composition in 120 participants with, or at risk of, metabolic syndrome. Each participant consumed 3 g/day of powder (spice or placebo). Data related to different parameters were collected from participants at the baseline, midpoint, and endpoint of the intervention. Over the 12-week interventions, there was an improvement in a number of biochemical indices of metabolic syndrome, including fasting blood glucose, HbA1c, LCL, and total cholesterol associated with supplementation with the spices when compared to a placebo. This study provides evidence to support the adjunct use of supplementation for those at risk of metabolic syndrome and its sequelae.

Uncommon triggers of insulin autoimmune syndrome: a case report.

BACKGROUND: Insulin autoantibody syndrome (IAS), or Hirata disease, is caused by high concentrations of insulin autoantibodies, which result in spontaneous, mainly post-prandial, hypoglycemic episodes. We report a case of a previously healthy 67-year-old man presenting with recurrent fasting hypoglycemia culminating in a diagnosis of insulin autoimmune syndrome linked to omeprazole and probably spices, namely, coriander, and ginger. CASE PRESENTATION: A previously healthy 67-year-old Sinhalese man presented with recurrent syncopal attacks for 3 months, which were found to be hypoglycemic episodes. He experienced mainly fasting hypoglycemic attacks, at a frequency gradually increasing to daily attacks. His cardiovascular, respiratory, abdominal, and neurologic examinations were normal. He was found to have insulin levels > 6000 mU/L and a post-polyethylene glycol insulin recovery of less than 9.5%. Contrast-enhanced computed tomography of the pancreas was normal. The diagnosis of insulin autoantibody syndrome was confirmed by testing for the insulin autoantibody level, yielding a level of > 300 U/mL. With regard to a possible trigger, he had a history of omeprazole intake for 2 weeks, 4 weeks prior to the onset of symptoms. He also consumed an herbal supplement containing coriander and ginger extracts daily for a period of 1 year, approximately 2 years prior to the onset of hypoglycemic attacks. He was commenced on prednisolone 30 mg daily, and hypoglycemic episodes responded dramatically, and thus he was tapered off corticosteroids. CONCLUSION: Omeprazole-induced insulin autoantibody syndrome is likely in this patient; however, the known hypoglycemic effects of coriander and ginger make it worthwhile to consider a possible association with insulin autoantibody syndrome. In addition, this case report highlights the need to consider insulin autoantibody syndrome even in patients presenting with fasting hypoglycemic attacks.

Comparative pharmacokinetics of multi-components in normal and stomach cold syndrome rats after oral administration of Zingiberis Rhizoma - Jujubae Fructus herb pair and its single herb extracts by UHPLC-MS/MS.

The Zingiberis Rhizoma - Jujubae Fructus herb pair (ZJHP) is a classic herb pair in traditional Chinese medicine. The herb pair shows the effect of dispelling cold, harmonizing the middle and improving gastrointestinal function, and is widely used for patients with stomach cold syndrome (SCS), stomachache and anemofrigid cold. The gingerols, shogaols, flavonoids and triterpenic acids are the important bioactive ingredients of ZJHP. However, few pharmacokinetic studies have been investigated in vivo for the above compounds. To comprehend the kinetics of active components and promote their curative application, a fast and sensitive ultra-high performance liquid chromatography coupled with mass spectrometry (UHPLC-MS/MS) method was established for simultaneous determination of 12 analytes in normal and SCS rats in this study. The results showed that the pharmacokinetic parameters (Cmax, Tmax, t1/2z, MRT0-t, AUC0-t and AUC0-∞) in SCS model were significantly different from those in normal rats. In addition, the pharmacokinetics of rats given ZJHP were also varied from single herb oral administration, especially in model condition. These results indicated that the in vivo processes of the above analytes changed under pathological conditions and the compatibility of the herb pair could significantly influence the absorption of active components, which might provide an insight and further supports for the clinical application of ZJHP.

Effect of thyme, ginger, and their nano-particles on growth performance, carcass characteristics, meat quality and intestinal bacteriology of broiler chickens.

This study was conducted to evaluate the effects of thyme, ginger, and their nano-particles, as alternatives to antibiotic growth promotors (AGP), on productive performance, carcass traits, meat quality and gut health of broiler chickens. A total of 270 one-day-old broiler chicks were randomly distributed into 6 groups, each consisting of 3 replicates (n = 15 chicks/replicate). The birds in group 1 were fed the control diet which contained neither antibiotic growth promotors nor phytogenic feed additives (PFA). Birds in group 2 were fed diets containing 0.05% of AGP (Bacitracin methylene disalicylate). Chicks in group 3 and 4 were fed diets supplemented with 1.0% of thyme and ginger, respectively, whereas birds in group 5 and 6 were offered diets including 0.10% of nano-thyme and nano-ginger, respectively. The experiment lasted for 35 days. It was found that thyme and ginger with their nano-products, like the antibiotic, improved the body weight, weight gain and feed conversion rate of birds. The effect of ginger and nano-ginger on body weight and weight gain was greater than other treatments. During the overall feeding period, the feed cost of production was the highest in antibiotic group, but was the lowest in ginger and nano-ginger treatments. There was no effect of dietary treatments on carcass yield or organs weight except bursa of Fabricius and abdominal fat. Thyme, ginger and their nano-composites increased the weight of bursa and reduced the abdominal fat amount. The phytogenic additives and their nano-particles improved the colour, water holding capacity, and flavor of meat. Moreover, these additives reduced the total intestinal bacterial count as well as the total aerobic mesophilic count of meat. The effect of PFA and their nano-particles on the bacterial count was similar to that of antibiotic. In conclusion, thyme and ginger with their nano- particles can be considered as promising agents in feeding of broilers to improve the growth performance, gut health and meat quality. Moreover, these additives can be used as alternatives to AGP to overcome its health hazards and the high cost. The nanotechnology of herbal plants enables them to be added in smaller amounts in poultry diets with producing the same effect of raw ingredients, and this could be due to the higher bioavailability.

Zingiber officinale promotes autophagy and apoptosis in human oral cancer through the C/EBP homologous protein.

The rhizome of Zingiber officinale (Z. officinale), commonly known as ginger, has been characterized as a potential drug candidate due to its antitumor effects. However, the chemotherapeutic effect of ginger on human oral cancer remains poorly understood. In this study, we examined the effects of an ethanol extract of Z. officinale rhizomes (ZOE) on oral cancer and identified the components responsible for its pharmacological activity. ZOE exerts its inhibitory activity in oral cancer by inducing both autophagy and apoptosis simultaneously. Mechanistically, ZOE-induced autophagy and apoptosis in oral cancer are attributed to the reactive oxygen species (ROS)-mediated endoplasmic reticulum stress response. Additionally, we identified two active components of ZOE, 1-dehydro-6-gingerdione and 8-shogaol, which were sufficient to stimulate autophagy initiation and apoptosis induction by enhancing CHOP expression. These results suggest that ZOE and its two active components induce ROS generation, upregulate CHOP, initiate autophagy and apoptosis, and hold promising therapeutics against human oral cancer.

Revealing the material basis and mechanism for the inhibition of intestinal peristalsis by Zingiber officinale Roscoe through integrated metabolomics, serum pharmacochemistry, and network pharmacology.

Abnormal relaxation and contraction of intestinal smooth muscle can cause various intestinal diseases. Diarrhea is a common and important public health problem worldwide in epidemiology. Zingiber officinale Roscoe (fresh ginger) has been found to treat diarrhea, but the material basis and mechanism of action that inhibits intestinal peristalsis remain unclear. Metabolomics and serum pharmacology were used to identify differential metabolites, metabolic pathways, and pharmacodynamic substances, and were then combined with network pharmacology to explore the potential targets of ginger that inhibit intestinal peristalsis during diarrhea treatment, and the targets identified were verified using molecular docking and molecular dynamic simulation. We found that 25 active components of ginger (the six most relevant components), 35 potential key targets (three core targets), 40 differential metabolites (four key metabolites), and four major metabolic pathways were involved in the process by which ginger inhibits intestinal peristalsis during diarrhea treatment. This study reveals the complex mechanism of action and pharmacodynamic material basis of ginger in the inhibition of intestinal peristalsis, and this information helps in the development of new Chinese medicine to treat diarrhea and lays the foundation for the clinical application of ginger.

Therapeutic effect of ginger garlic powder in rats with induced diabetes.

The purpose of this study was to examine the potential hypoglycemic effects of administering ginger (Zingiber officinale) and garlic (Allium sativum) to rats with induced type 2 diabetes. A total of forty-five male adult albino rats were randomly assigned to five groups. The groups were named Normal Control, Diabetic Control, Ginger group, Garlic group and a combination group of ginger and garlic. Diabetes was produced in all groups, except the normal control group, using an intraperitoneal injection of streptozotocin at a dosage of 60 mg/body weight. During the course of two months, rats were administered varying amounts of ginger and garlic powders as part of their treatment After the experiment concluded, measurements were taken for glycated hemoglobin, serum glucose, insulin, cholesterol, high density protein, low density protein and liver glycogen levels. These groups exhibited considerably greater serum insulin and high-density lipoprotein concentrations (P<0.05) compared to the diabetic control group. Conversely, body weight, fasting blood glucose, total cholesterol, low density lipoprotein, and glycated hemoglobin levels were significantly lower (P<0.05) in all groups compared to the diabetic control group. A statistically significant increase (P<0.05) increase shown in liver glycogen levels. This study proposes that the utilization of ginger and garlic powders improve the condition of type 2 diabetes and maybe reduce the risk of subsequent diabetic complications.

Evaluation of cytotoxic effect of siphonochilone from African ginger: an in vitro analysis.

Plants provide a wide array of compounds that can be explored for potential anticancer properties. Siphonochilone, a furanoterpene that represents one of the main components of the African plant Siphonochilus aethiopicus, shows numerous health benefits. However, to date, its antiproliferative properties have not been tested. The aim of this study was to analyze the cytotoxic effects of siphonochilone on a panel of cancer cell lines and its underlying mechanism of action. Our results demonstrated that siphonochilone exhibited significant cytotoxic effects on pancreatic, breast, lung, colon, and liver cancer cell lines showing a IC50 ranging from 22 to 124 µM at 72 h of treatment and highlighting its cytotoxic effect against MCF7 and PANC1 breast and pancreas cancer cell lines (22.03 and 39.03 µM, respectively). Cell death in these tumor lines was mediated by apoptosis by the mitochondrial pathway, as evidenced by siphonochilone-induced depolarization of the mitochondrial membrane potential. In addition, siphonochilone treatment involves the generation of reactive oxygen species that may contribute to apoptosis induction. In this work, we described for the first time the cytotoxic properties of siphonochilone and provided data about the molecular processes of cell death. Although future studies will be necessary, our results support the interest in this molecule in relation to their clinical application in cancer, and especially in breast and pancreatic cancer.

Encapsulation of gingerol into nanoliposomes: Evaluation of in vitro anti-inflammatory and anti-cancer activity.

Nanoliposomes (NLs) are ideal carriers for delivering complex molecules and phytochemical products, but ginger by-products, despite their therapeutic benefits, have poor bioavailability due to their low water solubility and stability. Crude ginger extracts (CGEs) and 6-gingerol were individually encapsulated within NLs for in vitro activity assessment. In vitro evaluation of anti-proliferative and anti-inflammatory properties of encapsulated 6-gingerol and CGE was performed on healthy human periodontal ligament (PDL) fibroblasts and MDA-MB-231 breast cancer cells. Encapsulation efficiency and loading capacity of 6-gingerol reached 25.23% and 2.5%, respectively. NLs were found stable for up to 30 days at 4°C with a gradual load loss of up to 20%. In vitro cytotoxic effect of encapsulated 6-gingerol exceeded 70% in the MDA-MB-231 cell line, in a comparable manner with non-encapsulated 6-gingerol and CGE. The effect of CGE with an IC50 of 3.11 ± 0.39, 7.14 ± 0.80, and 0.82 ± 0.55 µM and encapsulated 6-gingerol on inhibiting IL-8 was evident, indicating its potential anti-inflammatory activity. Encapsulating 6-gingerol within NLs enhanced its stability and facilitated its biological activity. All compounds, including vitamin C, were equivalent at concentrations below 2 mg/mL, with a slight difference in antioxidant activity. The concentrations capable of inhibiting 50% of 2,2-diphenyl-1-picrylhydrazyl (DPPH) substrate were comparable.

Growth performance, carcass traits and meat physical characteristics of growing Japanese quail fed ginger powder and frankincense oil as feed additives.

This work aimed to investigate the effects of dietary frankincense oil and ginger on the growth efficiency of growing Japanese quail, including live body weight, body weight gain, feed intake, feed conversion ratio, carcass traits, and physical characteristics of the meat. In total, 150 unsexed Japanese quail chicks that were 7 d old were utilized in the experiment. The chicks were randomly divided into 5 groups. Each group was divided into 3 replicates with ten birds in a completely randomized design. Group 1 received a basal diet without supplements and was used as a control group. Groups 2 and 3 received basal diets with 250 and 500 mg of ginger per kg of diet, respectively. Groups 4 and 5 received basal diets with 200 and 400 mg of frankincense oil per kg of diet, respectively. Results showed that BW of chicks received 500 mg of ginger and the 2 levels of frankincense oil at 5 wk of age, and 250 mg of ginger and 400 mg of frankincense oil at 6 wk significantly increased. BWG was significantly increased by using 500 mg of ginger and 2 levels of frankincense oil at 1 to 3 wk, 250 mg of ginger and 400 mg of frankincense oil at 3 to 6 wk, and 1 to 6 wk of age, in comparison with the control group. Treatments insignificantly influenced feed intake (FI), and feed conversion ratio (FCR) was improved considerably by using 250 mg of ginger and 400 mg of frankincense at 3 to 6 wk and 1 to 6 wk of age, respectively. Gizzard% was notably reduced with 200 mg of frankincense oil. The pH value of meat was significantly increased by having 2 levels of ginger. Still, water holding capacity and tenderness significantly decreased owing to 500 mg of ginger and 400 mg of frankincense oil. We can conclude that adding ginger and frankincense oil to Japanese quail diets may be beneficial.

In-silico prediction of anti-breast cancer activity of ginger (Zingiber officinale) using machine learning techniques.

INTRODUCTION: Indonesian civilization extensively uses traditional medicine to cure illnesses and preserve health. The lack of knowledge on the security and efficacy of medicinal plants is still a significant concern. Although the precise chemicals responsible for this impact are unknown, ginger is a common medicinal plant in Southeast Asia that may have anticancer qualities. METHOD: Using data from Dudedocking, a machine-learning model was created to predict possible breast anticancer chemicals from ginger. The model was used to forecast substances that block KIT and MAPK2 proteins, essential elements in breast cancer. RESULT: Beta-carotene, 5-Hydroxy-74'-dimethoxyflavone, [12]-Shogaol, Isogingerenone B, curcumin, Trans-[10]-Shogaol, Gingerenone A, Dihydrocurcumin, and demethoxycurcumin were all superior to the reference ligand for MAPK2, according to molecular docking studies. Lycopene, [8]-Shogaol, [6]-Shogaol, and [1]-Paradol exhibited low toxicity and no Lipinski violations, but beta carotene had toxic predictions and Lipinski violations. It was anticipated that all three substances would have anticarcinogenic qualities. CONCLUSION: Overall, this study shows the value of machine learning in drug development and offers insightful information on possible anticancer chemicals from ginger.
