Project description:Disorders of redox homeostasis and the excessive release of hydrogen peroxide (H2O2) are pivotal events in the pathogenesis of epilepsy, contributing to neuronal hyperexcitability, mitochondrial dysfunction, and subsequent cell death. Cordyceps sinensis (C. sinensis), a traditional Chinese medicine renowned for its tonic properties, has been traditionally used to alleviate a variety of ailments. Emerging evidence suggests that C. sinensis and its active constituents possess significant sedative and anti-inflammatory effects. Transcriptomic sequencing was conducted on the H2O2-induced cell lines treated with varying concentrations of the C. sinensis mixture and monomers to validate and integrate the findings. This research investigates the neuroprotective and anticonvulsant effects of C. sinensis extract against H2O2-induced oxidative stress and excitotoxicity in neuronal models of epilepsy.
Project description:Rhizoma coptidis (R.coptidis) is a widely cultivated traditional Chinese herb. Although the chemical profiles of R.coptidis have been established previously, the biological profiling of R.coptidis has not been conducted yet. Here, we collected R.coptidis varieties from four different regions as well as its analogue, Rabdosia serra (R.serra) were and performed genome-wide biological response fingerprinting (BioReF) on HepG2 cells using a gene expression array.
Project description:Cordyceps militaris and Cordyceps sinensis belong to belong to the same genus, but the different species, with immunity improvement, antibacterial, and antihypertensive effect, and the studies on the functions of Cordyceps militaris mainly focus on those of its polysaccharides and polypeptides. The latest studies have found that some of the polypeptides with immunomodulatory effect can widely regulate immune functions at multiple levels, improve immunity, and enhance immune functions to ensure the healthy body, showing an important significance. Cordyceps militaris polypeptide prepared with the enzymolysis method was taken as the research object in this study. The differentially expressed genes and the related cell signal transduction pathway were screened by mRNA expression microarray. STEM 1.3.6 software was used for the clustering of the gene functions, and David and KEGG database were applied for the analysis of the related functions. 1748 differentially expressed genes were selected finally and three of them were validated by qPCR. The results showed that gene Hist1h2bp, Ctsg, and Elane were involved in the regulation of Cordyceps militaris on the immune activity of mice. Gene Hist1h2bp, Ctsg and Elan may be the potential targets of Cordyceps militaris polypeptide, which may provide an important theory basis for the further research and development of Cordyceps militaris polypeptide.
Project description:Asthma is a chronic inflammatory airway disease characterized by airway inflammation and remodeling. The role of 15-oxo-5Z,8Z,11Z,13E-eicosatetraenoic acid (15-oxoETE), a 15-HETE metabolite catalyzed by 15-prostaglandin dehydrogenase (15-PGDH), has been relatively unexplored in asthma. In this study, we used RNA-seq to explore the effect of 15-KETE on the transcriptome of airway epithelial cells, aiming to identify its potential downstream targets and mechanisms of action.
Project description:Gene expression profiling of immortalized human mesenchymal stem cells with hTERT/E6/E7 transfected MSCs. hTERT may change gene expression in MSCs. Goal was to determine the gene expressions of immortalized MSCs.
