ABSTRACT

The use of non-pharmacological strategies to complement pharmacological approaches can enhance cancer pain management by promoting patient autonomy and increasing management effectiveness. This study aimed to explore the required behavioral adaptations and situational barriers that cancer patients encounter when utilizing non-pharmacological strategies to manage pain. We adopted an exploratory-descriptive qualitative research approach, purposive sampling, and semi-structured interview guidelines to conduct face-to-face interviews with 18 cancer patients experiencing moderate or severe levels of worst pain. Data were analyzed using inductive content analysis to explore patients' experiences. Five themes described the behavioral adaptations of patients using non-pharmacological strategies to deal with cancer pain: finding complementary therapies, utilizing assistive skills, adapting to assistive skills, diverting attention, and seeking help. Situational barriers faced by patients include being in the workplace or in a climate-affected environment. Behavioral adaptation is necessary for non-pharmacological strategies to coping with cancer pain. The behavioral skills can help the patients to overcome situational barriers to engagement with these strategies. Thus, health professionals are expected to help the patients acquire adequate behavioral adaptation and skills for self-pain management, and assess the effectiveness of the strategies.

ABSTRACT

As the second most abundant intracellular divalent cation, magnesium (Mg2+) is essential for cell functions, such as ATP production, protein/DNA synthesis, protein activity, and mitochondrial function. Mg2+ plays a critical role in heart rhythm, muscle contraction, and blood pressure. A significant decline in Mg2+ intake has been reported in developed countries because of the increased consumption of processed food and filtered/deionized water, which can lead to hypomagnesemia (HypoMg). HypoMg is commonly observed in cardiovascular diseases, such as heart failure, hypertension, arrhythmias, and diabetic cardiomyopathy, and HypoMg is a predictor for cardiovascular and all-cause mortality. On the other hand, Mg2+ supplementation has shown significant therapeutic effects in cardiovascular diseases. Some of the effects of HypoMg have been ascribed to changes in Mg2+ participation in enzyme activity, ATP stabilization, enzyme kinetics, and alterations in Ca2+, Na+, and other cations. In this manuscript, we discuss new insights into the pathogenic mechanisms of HypoMg that surpass previously described effects. HypoMg causes mitochondrial dysfunction, oxidative stress, and inflammation. Many of these effects can be attributed to the HypoMg-induced upregulation of a Mg2+ transporter transient receptor potential melastatin 7 channel (TRMP7) that is also a kinase. An increase in kinase signaling mediated by HypoMg-induced TRPM7 transcriptional upregulation, independently of any change in Mg2+ transport function, likely seems responsible for many of the effects of HypoMg. Therefore, Mg2+ supplementation and TRPM7 kinase inhibition may work to treat the sequelae of HypoMg by preventing increased TRPM7 kinase activity rather than just altering ion homeostasis. Since many diseases are characterized by oxidative stress or inflammation, Mg2+ supplementation and TRPM7 kinase inhibition may have wider implications for other diseases by acting to reduce oxidative stress and inflammation.

ABSTRACT

This study aimed to determine whether the lotus leaf extract (LLE) had the effect of treating salpingitis in laying hens. First, the salpingitis model was established by the method of bacterial infection. Differential genes between salpingitis and healthy laying hens were identified by transcriptome sequencing, and GO and KEGG enrichment analyses were performed. Groups of treatment of antibiotics and LLE were established to verify the feasibility of the lotus leaf extract in treating salpingitis. Furthermore, the active component and pharmacological effects of LLE were identified using the UPLC-Q-TOF-MS and network pharmacology technique. At last, the mechanism of LLE treating salpingitis was further evaluated by DF-1 cells infected with bacteria. The results showed that LLE significantly reduced the levels of TLR4 and IFN-γ (P < 0.05), accelerated the levels of IgA and IgG (P < 0.05), regulated the levels of SOD and MDA (P < 0.05) in laying hens with salpingitis. A total of 1,874 differential genes were obtained according to the transcriptome sequencing. It was revealed a significant role in cell cycle and apoptosis by enrichment analysis. In addition, among the 28 components identified by UPLC-Q-TOF-MS, 20 components acted on 58 genes, including CDK1, BIRC5, and CA2 for treating salpingitis. After bacterial infection, cells were damaged and unable to complete the normal progression of the cell cycle, leading to cell cycle arrest and further apoptosis formation. However, with the intervention of LLE, bacterial infection was resisted. The cells proliferation was extensively restored, and the expression of NO was increased. The addition of LLE significantly decreased cell apoptosis. The G1 phase increased, the S phase and the G2 phase decreased in the model group; after the intervention of LLE, the G1 phase gradually returned to the average level, and G2 and S phases increased. The mRNA expression levels of BIRC5, CDK1, and CA2 were consistent with the predicted results in network pharmacology. At the same time, the mRNA expression levels of Caspase-3 and Caspase-7 were reduced after added with LLE. The mRNA expression levels of TNF-α, TRADD, FADD, Caspase-8, Caspase-10, and Caspase-9 (P < 0.05), which would inhibit death receptor activation and decrease the apoptotic cascade, were upregulated after bacterial infection. However, the results in LLE groups were downregulated (P < 0.05). Meanwhile, the mRNA expression levels of BCL-2 in LLE groups were increased significantly compared with it in model group (P < 0.05). Notably, LLE administration inhibited apoptosis and regulated the cell cycle distribution in the salpingitis induced by bacterial infection. These results indicated that the LLE attenuated bacterial-induced salpingitis by modulating apoptosis and immune function in laying hens.

ABSTRACT

Purpose: To investigate whether wogonin, a key bioactive ingredient of Huangqi Guizhi formula (HQGZ formula; a Traditional Chinese Medicine herbal formula) according to network pharmacology analysis, has analgesic effects on discogenic low back pain (LBP) via regulating the nerve growth factor (NGF) in intervertebral discs (IVDs). Methods: The lumbar IVDs of rats were punctured to discogenic LBP, and the therapeutic effect of orally administrated HQGZ for discogenic LBP was investigated by measuring mechanical and cold allodynia and histological analysis. A network pharmacology analysis was conducted to search for bioactive ingredients from the HQGZ formula, and wogonin was suggested to be the most possible bioactive ingredient for LBP treatment. Subsequently, the analgesic effect of wogonin was investigated in the LBP model, and the gene expression of propain peptides in the bilateral dorsal root ganglia was analyzed using RT-PCR. Finally, immunohistochemical staining was performed for NGF expression of NGF in the IVDs to determine whether wogonin treatment would ameliorate NGF-induced LBP. Results: Oral administration of HQGZ for two weeks significantly ameliorated puncture-induced IVD degeneration (IDD) and LBP. In addition, the network pharmacology analysis revealed that wogonin, quercetin, and kaempferol were the potential candidate components of HQGZ for LBP treatment. Furthermore, we proved that wogonin had significant analgesic effects in the LBP model. Finally, wogonin was demonstrated to suppress the upregulated NGF in the IVD and ameliorate NGF-induced LBP in rats. Conclusions: The HQGZ formula has significant analgesic effects for LBP. In addition, the bioactive ingredient of wogonin was extracted from HQGZ and ameliorated LBP by suppressing the overexpressed NGF in degenerated IVDs. Therefore, wogonin has potential to be alternative treatment for LBP in clinical.

ABSTRACT

Marine shell resources have received great attention from researchers owing to their unique merits such as high hardness, good toughness, corrosion resistance, high adsorption, and bioactivity. Restricted by the level of comprehensive utilization technology, the utilization rate of shells is extremely low, resulting in serious waste and pollution. The research shows that the unique brick-mud structure of shells makes them have diverse and good functional characteristics, which guides them to have great utilization potential in different fields. Hence, this review highlights the constitutive relationship between microstructure-function-application of shells (e.g., gastropods, cephalopods, and amniotes), and the comprehensive applications and development ideas in the fields of biomedicine, adsorption enrichment, pHotocatalysis, marine carbon sink, and environmental deicer. It is worth mentioning that marine shells are currently well developed in three areas: bone repair, health care and medicinal value, and drug carrier, which together promote the progress of biomedical field. In addition, an in-depth summary of the application of marine shells in the adsorption and purification of various impurities such as crude oil, heavy metal ions and dyes at low-cost and high efficiency is presented. Finally, by integrating thoughts and approaches from different applications, we are committed to providing new pathways for the excavation and future high-value of shell resources, clarifying the existing development stages and bottlenecks, promoting the development of related technology industries, and achieving the synergistic win-win situation of economic and environmental benefits.

ABSTRACT

BACKGROUND: Ginsenosides, phenolic compounds, and polysaccharides are the bioactive constituents of Panax ginseng Meyer. Compound K (CK) is a secondary ginsenoside with better bioavailability. It is also a promising anticancer agent. PURPOSE: We aimed to evaluate the effect of CK on prostate cancer (PCa) and its potential mechanisms. STUDY DESIGN: The proliferation, migration and cell cycle of PCa cells after CK treatment were assessed in various PCa cell lines. Docetaxel was used as a positive control drug. Unlike other published studies, the potential mechanisms of CK (50 µM) were investigated by an unbiased global transcriptome sequencing in the current study. METHODS: Key CK related genes (CRGs) with prognostic significance were identified and verified by bioinformatic methods using data from the TCGA dataset and GSE21034 dataset. The role of CDK1 in the effect of CK treatment on PCa cells was investigated by overexpression of CDK1. RESULTS: CK inhibited the proliferation and migration of PCa cells at concentrations (less than 25 µM) without obvious cytotoxicity. Five key CRGs with prognostic significance were identified, including CCNA2, CCNB2, CCNE2, CDK1, and PKMYT1, which are involved in cell cycle pathways. CK inhibited the expression of these 5 genes and the cell cycle of PCa cells. According to the results of bioinformatic analysis, the expression of the five key CRGs was strongly associated with poor prognosis and advanced pathological stage and grade of PCa. In addition, CK could restore androgen sensitivity in castration-resistant PCa cells, probably by inhibiting the expression of CDK1. After CDK1 overexpression, the inhibition of proliferation and migration of PCa cells by CK was decreased. The inhibition on the phosphorylation of AKT by CK was also reduced. CONCLUSION: CK can inhibit PCa cells, and the mechanisms may be associated with the inhibition of cell cycle pathways through CDK1. CK is also a potential clinical anticancer agent for treating PCa.

ABSTRACT

Objective: In this study, the aim was to investigate the inhibitory effect of 6,6'-bieckol on the migration and epithelial-mesenchymal transition (EMT) of non-small cell lung cancer (NSCLC) cells, and explore its potential molecular mechanisms. Methods: Cell migration was measured using a CCK8, wound healing, and transwell migration assay. Apoptosis was determined using an Annexin V/propidium iodide staining. Western blotting and immunofluorescence were used to examine the expression level of apoptosis-related proteins and EMT marker proteins. Results: The results showed that 6,6'-bieckol inhibited migration and induced apoptosis of NSCLC cells. Furthermore, 6,6'-bieckol had significantly up-regulated the E-cadherin and down-regulated Snail1 and Twist1 transcriptional levels. 6,6'-Bieckol might inhibit TGF-ß-induced EMT by down-regulating Snail1 and Twist1 and up-regulating E-cadherin in lung cancer cells. Conclusion: It is suggested that 6,6'-bieckol has the potential to be developed as a therapeutic candidate for lung cancer.

ABSTRACT

ETHNOPHARMACOLOGICAL RELEVANCE: Shouhui tongbian capsule (SHTC) is a commercial Chinese patent medicine used in the treatment of constipation. However, its mechanism of action remains unclear. AIM OF THE STUDY: The present study was undertaken to assess SHTC relieved effects on the clinical symptoms of loperamide (LOP) induced constipation in Sprague Dawley (SD) rat model and to clarify the relationship between the protective effect of SHTC on constipation and the gut microbiota. MATERIALS AND METHODS: Constipation male SD rats models were induced with solution of LOP (1.5 mg/kg bw), and rats were treated with an oral dose of SHTC (35, 70 mg/kg bw) three times a day after successful modeling. All rats were assessed weekly by change in body weight, gastric emptying rate, fecal moisture content and wet/dry weight. Hematoxylin and eosin (H&E) were used to observe parts of the rats small intestine. The gut microbiota in colonic contents was analyzed using 16SrRNA gene sequencing. Contents of short-chain fatty acids (SCFAs) were analyzed by gas chromatography-mass spectrometer (GCMS). RESULTS: The results confirmed the therapeutic effects of SHTC on constipation. Specifically, SHTC could alleviate the decrease in body weight, gastric emptying rate and fecal moisture content caused by LOP-induced constipation. The pathological damage of small intestine was significantly improved by H&E staining. Notably, SHTC increased the relative abundances of Lactobacillus and the ratio of Firmicutes to Bacteroides (F/B). In addition, the content of acetic acid and propionic acid was significantly increased in constipated rats fed with SHTC. CONCLUSION: SHTC could ameliorate the development of LOP-induced constipation in rats by remodeling the structure of gut microbial community and regulating production of intestinal metabolites.

ABSTRACT

Excessive solar ultraviolet (SUV) radiation often causes dermatitis, photoaging, and even skin cancer. In the pathological processes of SUV-induced sunburn, JNK is activated by phosphorylation, and it in turn phosphorylates its downstream transcription factors, such as ATF2 and c-jun. The transcription factors further regulate the expression of pro-inflammatory genes, such as IL-6 and TNF-α, which ultimately leads to dermatitis. Therefore, inhibiting JNK may be a strategy to prevent dermatitis. In this study, we screened for worenine as a potential drug candidate for inhibiting sunburn. We determined that worenine inhibited the JNK-ATF2/c-jun signaling pathway and the secretion of IL-6 and TNF-α in cell culture and in vivo, confirming the role of worenine in inhibiting sunburn. Furthermore, we determined that worenine bound and inhibited JNK2 activity in vitro through the MST, kinase, and in vitro kinase assays. Therefore, worenine might be a promising drug candidate for the prevention and treatment of SUV-induced sunburn.

ABSTRACT

Gut barrier makes a huge research gap between in vivo and in vitro studies of orally bioactive polysaccharides: whether/how they contact the related cells in vivo. A hyperbranched heteroglycan RAP from Radix Astragali, exerting antitumor and immunomodulatory effects in vitro and in vivo, is right an example. Here, we determined first that RAP's antitumor activity is immune-dependent. Being undegraded and non-absorbing, RAP quickly entered Peyer's patches (PPs) in 1 h where it directly targeted follicle dendritic cells and initiated antitumor immune responses. RAP was further delivered to mesenteric lymph node, bone marrow, and tumor. By contrast, the control Dendrobium officinale polysaccharide did not enter PPs. These findings revealed a blood/microbiota-independent and selective lymphatic route for orally administrated RAP to directly contact immune cells and trigger antitumor immune responses. This route bridges the research gap between the in vitro and in vivo studies and might apply to many other bioactive polysaccharides.

ABSTRACT

Monoterpene Perillaldehyde (PAE) is a major component of the essential oil extracted from perilla plants (Perilla frutescens), which has been used as a leafy vegetable and a medicinal agent. PAE has gained a lot of attention in recent years because of its antifungal and other microbial activities and, human health benefits. PAE has also been used as food additives, perfume ingredients, and traditional medicine concoctions. Biological analyses of PAE have revealed that it has good antioxidant activities and can serve as organic fruit and food preservative. Animal studies indicated potent anticancer, anti-depressant, and anti-inflammatory effects of PAE. Also, PAE is certified "generally recognized as safe" (GRAS) and not mutagenic. However, moderation during usage is advisable, as minor adverse effects are associated with a very high dosage. Despite the newly reported findings, its properties have not been thoroughly summarized and reviewed. Also, clinical trials and official large-scale field applications of PAE in the agricultural sectors are yet to be reported. In this review, updated PAE research progress was provided, focusing on its antifungal and other antimicrobial properties and the mechanisms behind it, phytochemical profile, pharmacological effects, and safety concerns.HighlightsIsolation and recovery techniques of PAE from perilla plants have been developed and improved in recent years.PAE is a potential anti-oxidant and antifungal agent that can be widely used in the food industry.PAE can be developed into drug ingredients for pharmaceutical industries due to its anti-inflammatory, anti-cancer and anti-depressant activities.PAE can be safely used in human when low and moderate dosage is used.

ABSTRACT

Background Dietary Mg intake is associated with a decreased risk of developing heart failure, whereas low circulating Mg level is associated with increased cardiovascular mortality. We investigated whether Mg deficiency alone could cause cardiomyopathy. Methods and Results C57BL/6J mice were fed with a low Mg (low-Mg, 15-30 mg/kg Mg) or a normal Mg (nl-Mg, 600 mg/kg Mg) diet for 6 weeks. To test reversibility, half of the low-Mg mice were fed then with nl-Mg diet for another 6 weeks. Low-Mg diet significantly decreased mouse serum Mg (0.38±0.03 versus 1.14±0.03 mmol/L for nl-Mg; P<0.0001) with a reciprocal increase in serum Ca, K, and Na. Low-Mg mice exhibited impaired cardiac relaxation (ratio between mitral peak early filling velocity E and longitudinal tissue velocity of the mitral anterior annulus e, 21.1±1.1 versus 15.4±0.4 for nl-Mg; P=0.011). Cellular ATP was decreased significantly in low-Mg hearts. The changes were accompanied by mitochondrial dysfunction with mitochondrial reactive oxygen species overproduction and membrane depolarization. cMyBPC (cardiac myosin-binding protein C) was S-glutathionylated in low-Mg mouse hearts. All these changes were normalized with Mg repletion. In vivo (2-(2,2,6,6-tetramethylpiperidin-1-oxyl-4-ylamino)-2-oxoethyl)triphenylphosphonium chloride treatment during low-Mg diet improved cardiac relaxation, increased ATP levels, and reduced S-glutathionylated cMyBPC. Conclusions Mg deficiency caused a reversible diastolic cardiomyopathy associated with mitochondrial dysfunction and oxidative modification of cMyBPC. In deficiency states, Mg supplementation may represent a novel treatment for diastolic heart failure.

ABSTRACT

Radix Astragali polysaccharide RAP has been reported to play a crucial role in hematopoiesis without a clear mechanism. In this study, RAP's effects to enhance the recovery of cyclophosphamide (Cy)-suppressed bone marrow and blood cells is confirmed in vivo first. Confocal micrographs demonstrated the interesting direct binding of FITC-RAP to hematopoietic stem cells (HSC) in bone marrow. RAP protects both mice and human HSC in terms of cell morphology, proliferation, and apoptosis. RNA-sequencing and shRNA approaches revealed FOS to be a key regulator in RAP's protection. These evidences provide an unreported mechanism that RAP directly protects hematopoietic stem cells from chemotherapy-induced myelosuppression by increasing FOS expression.

ABSTRACT

On February 6, 2020, Xiaogan City became the second most seriously affected city with coronavirus disease 2019 (COVID-19), outside Wuhan district, Hubei Province, China. The objectives are to study the clinical features of COVID-19 patients and assess the relationship between the severity of COVID-19, age, and C-reactive protein (CRP) levels. The retrospective data of 134 COVID-19 patients hospitalized in 3 hospitals of Xiaogan City, between February 1 and March 1, 2020, was collected. This study documented COVID-19 patients. Clinical data in terms of body temperature, history of travel, and direct contact with COVID-19 patients, and incubation period was collected. Out of the 134 patients, only 5 required intensive care. Moreover, 2 patients succumbed during this period. The median age of patients was 45 (33-56) years. The most common symptoms at the onset of disease were fever (66.4%), cough (33, 6%), and sore throat (14.7%). Amongst the medicines used, antiviral agents (92.3%) followed by the traditional Chinese medicine (89.5%) were most commonly used. In both the crude and adjusted (I to III) models, odds ratio and its 95% confidence interval for both age and CRP levels were > 1. Moreover, the smooth curve fitting graph reflected that the severity of COVID-19 was positively correlated with both age and CRP levels (all P value < 0.05). The signs and symptoms of COVID-19 patients were fairly moderate. The health care professionals treating the COVID-19 patients should be aware of the increased likelihood of progression to severe COVID-19 in elderly patients and those with high CRP levels.

ABSTRACT

OBJECTIVES: This study aimed to explore the effects of glutamine on hypermetabolic reactions in burned rats and its underlying mechanism. METHODS: Fifty-five Sprague-Dawley rats were randomly divided into three groups, namely, the control (C), burned (B), and burned + glutamine (B + G) groups. Rats in the glutamine treatment group were supplemented with 1 g glutamine per kg body weight. Changes in body weight and resting energy expenditure in all groups were observed daily. Blood glucose and glucose tolerance level were measured on days 1, 3, 7, 10 and 14 after burn injury. On days 7 and 14 after injury, the rats were sacrificed, and the weight and protein content of the skeletal muscle were measured. Moreover, the level of glutamine, inflammatory mediator, nicotinamide adenine dinucleotide phosphate (NADPH), glutathione, and the activity of glutamine metabolic enzymes were measured. RESULTS: The hypermetabolic reaction after burn injury was significantly inhibited by glutamine administration, and the range of variations in the resting energy expenditure and body weight indicators was narrowed remarkably (P < 0.05 or 0.01), whereas the weight and protein content of the skeletal muscle returned to normal (P < 0.05 or 0.01). Glutamine could increase glutaminase activity in various tissues, promote the utilization of glutamine, and appropriately reduce the degree of organ damage and inflammatory response (P < 0.05 or 0.01). Furthermore, glutamine could promote the synthesis of the reducing substances NADPH and glutathione (P < 0.05 or 0.01). CONCLUSIONS: Glutamine administration effectively reduces hypermetabolic reactions by promoting NADPH synthesis, inhibiting oxidative stress, and improving glutamine utilization after burn injury.

ABSTRACT

Perillaldehyde (PAE), a natural monoterpenoid agent extracted from Perilla frutescence, PAE has been reported to present various physiological capabilities, such as anti-inflammation, anti-oxidative and anti-fungal. In this study, we show that PAE exhibits strong antifungal activity against Candida albicans (C. albicans). C. albicans, a fungal pathogen with high incidence of antifungal resistance in clinical settings, is the major cause of oropharyngeal candidiasis (OPC). OPC is characterized by inflammatory immunological responses to fungal infections. Our in vitro results show PAE inhibited several virulence attributes of C. albicans including biofilm formation, yeast-to-hyphal transition and secreted aspartic proteinases (SAPs) gene expression. Using an experimental murine model of OPC, we found that PAE inhibited NLRP3 inflammasome assembly, reduced the excessive accumulation of ROS and prevented the p65 transfer in nuclear; processes all leading to reduced inflammation burden in the host. Together, this supports use PAE as a promising new agent to improve OPC.

ABSTRACT

BACKGROUND AND OBJECTIVES: This study aimed to evaluate whether B vitamins supplementation would improve dyslipidemia, alleviate inflammatory state of patients with stable coronary artery disease (SCAD). METHODS AND STUDY DESIGN: We conducted a randomized, double-blind, 12-week, placebo-controlled trial involving adults with SCAD, and who were randomly divided into B vitamins group (folic acid and VB-6) and control group (placebo tablet). Blood tests had also been performed at baseline and endpoint. RESULTS: After 12 weeks of intervention, B vitamins supplementation significantly improved the concentration of serum TG, TC and HDL-C (p<0.05). Changes of serum homocysteine in B vitamins treatment were significantly different compared to placebo by the multivariate-adjusted analysis (3.02±2.35 vs 1.55±1.58 p<0.001). Meanwhile, the levels of IL-1ß and IL-10, significant difference were observed between two groups after adjustment for confounding factors. CONCLUSIONS: Supplementation with B vitamins significantly improves lipid metabolism, alleviate inflammation and serum homocysteine concentration in patients with SCAD.

ABSTRACT

Gut dysbiosis induced by high-fat diet (HFD) may result in low-grade inflammation leading to diverse inflammatory diseases. The beneficial effects of probiotics and prebiotics on obesity have been reported previously. However, their benefits in promoting human health and the underlying mechanisms still need to be further characterized. This study is aimed at understanding how probiotic Bacillus licheniformis Zhengchangsheng® (BL) and prebiotic xylooligosaccharides (XOS) influence the health of a rat model with HF (60 kcal %) diet-induced obesity. Five groups of male Sprague Dawley (SD) rats were fed a normal fat diet (CON) or an HFD with or without BL and XOS supplementation for 3 weeks. Lipid profiles, inflammatory biomarkers, and microbiota composition were analyzed at the end of the experiment. Rats fed an HFD exhibited increased body weight and disordered lipid metabolism. In contrast, combined BL and XOS supplementation inhibited body weight gain and returned lipid metabolism to normal. Furthermore, BL and XOS administration changed the gut microbiota composition and modulated specific bacteria such as Prevotellaceae, Desulfovibrionaceae, and Ruminococcaceae. In addition, supplements of combined BL and XOS obviously reduced the serum LPS level, which was significantly related to microbial variations. Our findings suggest that modulation of the gut microbiota as a result of probiotic BL and prebiotic XOS supplementation has a positive effect on HFD-induced obesity in rats.

ABSTRACT

Candida albicans invasion is one of the most serious fungal infections in clinical history. In recent years, because of the widespread use of immunosuppressive drugs, chemotherapy drugs, glucocorticoids, and broad-spectrum antibiotics, serious drug resistance has been reported; therefore, a new type of antifungal drug needs to be developed. In this study, we found that Nerol (NEL) had strong antimicrobial activity and 0.77 µL/mL NEL was the minimum inhibitory concentration (MIC) effective against C. albicans. We determined the change of the growth curve of NEL for C. albicans, to identify the trend of NEL activity against C. albicans. Through the determination of the ergosterol content and glucose-induced extracellular fluid acidification of NEL on C. albicans, we found that NEL inhibits the growth of C. albicans by destroying cell membranes. This finding was also supported by the expression of SAP (secreted aspartyl proteinase) involved in cell membrane synthesis. Finally, demonstrations of phenotype investigation, colony-forming unit (CFU) counts, and PAS (periodic acid-Schiff) staining were conducted to prove that NEL had the ability to treated mouse oral C. albicans infection and vaginal C. albicans infection. This research may help us to investigate new antimicrobial agents for treating C. albicans infections. KEY POINTS: • NEL can inhibit the growth of C. albicans. • NEL destroys the cell membrane formation and permeability of C. albicans. • NEL can treat vulvovaginal candidiasis and oropharyngeal candidiasis in mice. • NEL could be used as a possible antifungal agent.
