Project description:Donepezil, an acetylcholinesterase (AChE) inhibitor, was approved by FDA for the symptomatic therapies of patients with Alzheimer’s disease (AD) in 1996. Although donepezil have been regarded as the standard and first-line treatment for AD, the capacity of such drugs to alter the underlying disease process is still unclear. In this study, we sought to explore the possible protective mechanism of donepezil in triple-transgenic Alzheimer’s disease (3×Tg-AD) mice model. 3×Tg-AD mice were treated for 4 months with donepezil (1.3 mg /kg) and its effects were evaluated by behavioral tests and molecular analysis. The cognition of donepezil-treated mice was restored significantly. Reduced levels of soluble and insoluble amyloid beta 1-40 (Aβ 1-40) and amyloid beta 1-42 (Aβ 1-42) as well as senile plaques were observed. Moreover, donepezil treatment prevented the dendritic spine loss in hippocampus neurons. We further investigated the effects of donepezil on the hippocampal protein of 3×Tg-AD mice by quantitative proteomics technology. Proteomic results indicated that donepezil significantly elevated the levels of PINK1, NFASC, MYLK2, and RASN in the hippocampus, and modulated axon guidance, mitophagy, mTOR signaling, and MAPK pathway. The results suggested that donepezil induced neuroprotective effects through multiple mechanisms.
Project description:In this project we aimed to investigate the effect of Goreisan (GRS, traditional herbal medicine) on HFpEF model heart failure mouse. HFpEF was induced by administration of high-fat diet (HFD)and N-nitro-L-arginine methyl ester (L-NAME), with or without GRS. Mouse heart proteome was analyzed with LC/MS/MS.
Project description:We investigated the effect of an oriental herbal medicine “Taeeumjowuitang” on phenotype characteristics and elucidated anti-obesity mechanism based on RNA-seq transcriptomic profiles in an obesity animal model comparison with green tea extract.
Project description:Pien Tze Huang (PZH) is herbal traditional Chinese medicine which was widely utilized in Asia for hepatic diseases. We constructed two groups hepatic fibrosis mice model using CCl4, one group using PZH treatment and another group replacing PZH with double distilled water. All 12 mice were fed for 8 weeks and then killed to have their liver tissue taken out. Small RNA-seq were used to identify miRNAs of PZH medicine effect for hepatic fibrosis. We found the expression of these miRNAs (mmu-miR-205-5p, mmu-miR-3064-5p, mmu-miR-205-5p, mmu-miR-370-3p, mmu-miR-665-3p) were changed in PZH medicine treatment for hepatic fibrosis study. Furthermore, Hmga2 and Fgf9, miRNAs corresponding target genes (Sp4, Slc2a6, Tln2, Hmga2, Ank3, Pax9, Fgf9), have been reported association with hepatic fibrosis.
Project description:Jakyak-gamcho-tang (JGT) is a herbal medicine that has been traditionally prescrived for pain control including muscular pain. Muscle atrophy is a disease that is characterized with a gradual muscle loss. Muscle atrophy is clearly observed in experimental animals that receive a repeated high-dose of an artificial glucocorticoid, dexamethasone (DEX). This transcriptome analysis aims to investigate the changes in global gene expression profiles in gastrocnemius (GA) and soleus (SO) muscle tissues from mice with DEX-induced muscle atrophy in the presence or absence of JGT co-treatment.
Project description:Interventions: Integrated traditional Chinese and Western medicine group:Standard western medicine treatment and Taking herbal granules ;Western medicine group:Standard western medicine treatment
Primary outcome(s): Disease-free survival
Study Design: Cohort study
Project description:Although patients of colorectal cancer use Traditional Chinese Medicine (TCM) herbal therapy extensively in China, no strong evidence exists to demonstrate the safety and survival outcomes of TCM herbal therapy combined with conventional western medicine for treatment of this disease. The purpose of this multi-center perspective cohort study is to evaluate the relationship between TCM herbal therapy and survival outcomes in patients with advanced colorectal cancer.
Project description:Personalized therapy of rheumatoid arthritis (RA) based on traditional Chinese medicine cold and hot syndromes is selection of the best treatment for an individual patient. Wutou Decoction (WTD) is one of the classic Chinese herbal formulae which achieve favorable therapeutic response in treating RA-cold syndrome. Microarray analysis based on the adjuvant induced arthritis model combined with characteristics of RA and cold/hot syndromes was performed to screen RA-cold and RA-hot-syndrome-related genes, as well as WTD effect genes.
Project description:The emergence of natural products and their derivatives has notably influenced cancer treatment, making morusinol, an herbal medicine-derived monomer, a promising candidate. To comprehensively assess the impact of morusinol on immune function, we conducted whole transcriptome analysis (RNA sequencing, RNAseq) on macrophages treated with either vehicle or morusinol.
