The increased resistance of Candida to conventional antifungals brings great challenges for the clinical treatment of Candida infections. Recently, more attention has been paid to the research on combination therapy, which is a potential therapeutic approach for overcoming Candida resistance. In the present study, we first investigated the interaction between gypenosides (Gyp) and fluconazole (FLC) against Candida albicans (C. albicans) in vitro and in vivo. The in vitro test revealed a synergistic antifungal activity between Gyp and FLC against FLC-resistant (FLCR) C. albicans and indifferent effects for FLC-susceptible (FLCS) C. albicans, with the fractional inhibitory concentration index of 0.2539-0.2578 and 1-1.5, respectively. Besides, Gyp displayed synergistic interaction with FLC against FLCRC. albicans performed biofilm over 4 h, with the fractional inhibitory concentration index less then 0.5. In vivo, the combined antifungal efficacy of Gyp with FLC was evaluated by Galleria mellonella (G. mellonella) larvae. Gyp plus FLC prolonged the survival rate and reduced tissue invasion of larvae infected with FLCRC. albicans. Further experiments to get a first hint at what antifungal mechanisms might be inhibition of early biofilm formation, suppression of drug efflux, and inhibition of yeast-hyphal conversion. These findings will provide a new approach for the treatment of C. albicans infection.Diabetic retinopathy (DR) is progressive damage to the retina and it's caused by damage to the blood-retinal barrier. Quercetin has pleiotropic action like anti-oxidant, regulation cell cycle &vascular integrity, and preventive effect of neuroinflammation. The present study is designed to investigate the nano-formulation of quercetin (NQ) in a zebrafish model of DR. The DR was developed by a single intraperitoneal injection of streptozotocin (STZ; 350 mg/kg). The acceleration of retinopathy was made on 7 days of diabetic zebrafish by intravitreal injection of STZ (20 μL of 7 % w/v of STZ stock solution). The treatment of NQ (5 and 10 mg/kg; i.p.) was administered for 21 consecutive days. The reference control i.e., dexamethasone (DEX, 10 mg/kg; i.p.) was also administered for 21 consecutive days. The sign of DR was assessed by eyeball/body weight ratio, eyeball weight, optomotor response (OMR), startle response (SR), phototactic response (PTR), and escape response (ER). Furthermore, the biochemical changes like plasma glucose and homocysteine (HCY) levels; and eye retinal tissue lipid peroxidation, reduced glutathione (GSH), and arginase reductase (AR) activity levels were assessed. The NQ found to attenuate the effect of STZ induced DR along with the regulation of biochemical abnormalities. And, it also comparable with reference drug treatment i.e., DEX treated group. Hence, NQ can be used for the treatment of diabetic associated retinopathy and neurosensory disorder visits anti-hyperglycemic, regulation of homocysteine pathway, reduction of lipid peroxidation, and free radical scavenging actions.Inflammation and poor viability of chondrocytes result in the degradation of cartilage as osteoarthritis (OA) progresses. The purpose of the present study was to investigate whether ursolic acid (UA) can protect chondrocytes and alleviate OA. Following stimulation with tumor necrosis factor-α (TNF-α), 5 μM UA displayed no cytotoxicity and reversed the up-regulation of the inflammatory factors MMP13, IL-1β, IL-6 and PTGS2, and down-regulation of the cartilaginous genes/proteins type II collagen and Aggrecan. RNA sequencing identified 533 common deferentially expressed genes (DEGs) of which TNF, PI3K-AKT, NOD-like receptor, cytokine receptor interaction and NF-κB pathways were of potential importance. Further notable DEGs in the most-highly expressed 10 pathways contributed to maintenance of cartilaginous ECM homeostasis and were involved in an inflammatory response. The expression of these most-enriched DEGs was reversed by UA following stimulation with TNF-α. Additional investigation demonstrated that treatment with UA inhibited TNF-α-induced nuclear translocation of p65 and phosphorylation of IκBα and AKT, and reversed TNF-α-induced up-regulation of P20, ACS and NLRP3. Furthermore, rat anterior cruciate ligament transection (ACLT) induced-OA was ameliorated by treatment with UA. In conclusion, these results suggest that UA activates chondrocytes through the NF-κB/NLRP3 inflammasome pathway, thus preventing cartilage degeneration in osteoarthritis.Cancer is one of the major threats to human health. It is of vital importance to reveal the mechanisms of tumorigenesis, identify effective biomarkers and develop novel treatments to improve patient outcome. EFNA1 (ephrinA1) is a member of the EFN family, and it has been studied extensively since its discovery in 1990. selleckchem Increasing evidence indicates that EFNA1 plays a pivotal role in the pathogenesis of tumors. We provide a detailed overview of the expression and prognostic value of EFNA1 in different types of human malignancies. We briefly discuss the mechanisms of EFNA1 induction in hypoxic environments and its pro-angiogenic function in different cancer cells. We describe the effects of EFNA1 on tumor growth, invasiveness and metastasis. We summarize recent advances in EFNA1-associated cancer therapeutics with emphasis on the prospect of novel anti-tumor methods based on EFNA1.In traditional Chinese medicine, the role of the liver in depression is highly valued, and liver-relieving drugs, such as Sinisan, are often used to treat depression; however, the mechanism whereby these drugs work remains unclear. The present study aimed to reveal possible antidepressant mechanisms of Sinisan (SNS) by analyzing hepatic proteomics in chronic unpredictable mild stress (CUMS) mice. Using the CUMS mouse model of depression, the antidepressant effects of SNS were assessed by the sucrose preference test (SPT) and forced swimming test (FST). Hepatic differentially expressed proteins (DEPs) after SNS treatment were investigated by tandem mass tag (TMT) based quantitative proteomics analysis. Then, a bioinformatics analysis of DEPs was conducted through hierarchical clustering, Venn analysis, Gene Ontology (GO) annotation enrichment, and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment. DEP genes were further validated by quantitative real-time polymerase chain reaction (qRT-PCR) analysis and western blotting.
