Project description:This program aims at identifying a muscle gene signature associated with aging in rat sarcopenia model The profiling data was analyzed by identifying genes that were up- and down-regulated at selected p value and fold change in the muscle of aged rats compared to the young controls.

Project description:To gain new insights into molecular changes in skeletal muscle aging and disease with a special focus on differential alternative splicing and senescence, we performed RNA-seq on rat gastrocnemius muscles of animals aged 6, 12, 18, 21, 24 and 27 months, using a rat sarcopenia model we had previously established.

Project description:To investigate the metabolic dysfunction in the process of sarcopenia, we collected the skeletal muscles from the participants of healthy aged, pre-sarcopenia and sarcopenia. We then performed gene expression profiling analysis using data obtained from RNA-seq of skeletal muscle tissue from healthy aged, pre-sarccopenia and sarcopenia.

Project description:Knee osteoarthritis (KOA), as a degenerative multifactorial disease, affects the quality of life and mental health of patients, and also brings a huge socioeconomic burden. Treating synovitis have shown promise as anti-inflammatory therapeutics in mitigating OA symptoms and disease progression. Here, by analysing synovial single-cell sequencing (scRNA-seq) data from KOA, we found that synovial fibroblasts (FLS) in OA synovium showed a distinct pro-inflammatory phenotype. We collected synovial tissue from patients with clinical OA as well as from healthy donors, and histological examination was consistent with findings in scRNA-seq. Inspired by recent cross-tissue fibroblast lineage studies, we identified by sequencing that healthy FLS in synovial tissues share transcriptome-level similarities with dermal fibroblasts (DFb). Subsequently, we revealed the local as well as systemic distribution of intra-articular injected DFbs by constructing/extracting two types of rat fibroblasts (luciferase DFbs as well as GFP DFbs). The results demonstrate that DFbs can be locally retained in the synovium for up to three weeks following targeted engrafting on it. And intra-articular injection does not result in DFbs migration to vital organs or the occurrence of histological changes in these organs. A rat model of KOA was constructed by anterior cruciate ligament transection (ACLT) in order to study the therapeutic effect of DFbs on KOA. After injection, the rats showed improvement in painful gait. In addition, histological as well as imaging results showed reduced synovitis and improvement in articular cartilage. Finally we verified the protective effect of DFbs on cytokine-stimulated chondrocytes in a co-culture system.
