BACKGROUND Knee osteoarthritis (KOA) is a degenerative knee disease commonly found in the ageing population. DNA methylation works with histone acetylation to participate in aging. Alterations of DNA methylation may involve the joint chondrocyte degeneration in KOA. The aim of this study is to detect DNA methylation changes in chondrocytes of rats with KOA. METHODS The rat KOA model was estab...
Mitochondria play a pivotal role in the orchestration of cell death pathways. Here, we show that the control of ubiquitin dynamics at mitochondria contributes to the regulation of apoptotic cell death. The unique mitochondrial deubiquitylase, USP30, opposes Parkin-dependent ubiquitylation of TOM20, and its depletion enhances depolarization-induced cell death in Parkin-overexpressing cells. Impo...
Harpins are produced by gram-negative phytopathogenic bacteria and typically elicit hypersensitive response (HR) in non-host plants. The characterization of harpins in Xanthomonas species is largely unexplored. Here we demonstrate that Xanthomonas produce a highly conserved single-stranded DNA-binding protein (SSB(X)) that elicits HR in tobacco as by harpin Hpa1. SSB(X), like Hpa1, is an acidic...
A novel chemical tool compound that is an antagonist of brassinolide (BL, 1)-induced rice lamina joint inclination was developed. Although 2-O-, 3-O-, 22-O-, or 23-O-methylation of BL causes a critical decrease in biological activity,(5) a crystal structure of the extracellular leucine-rich repeat (LRR) domain of BRASSINOSTEROID-INSENSITIVE I (BRI1) bound to BL(3,4) indicates that the loss of a...
Brassinosteroids (BR) play important roles in plant growth and development. Although BR receptors have been intensively studied in Arabidopsis, the BR receptors in soybean remain largely unknown. Here, in addition to the known receptor gene Glyma06g15270 (GmBRI1a), we identified five putative BR receptor genes in the soybean genome: GmBRI1b, GmBRL1a, GmBRL1b, GmBRL2a, and GmBRL2b. Analysis of t...
Breast cancer is one of the most common cancers in women and it is highly treatable by radiotherapy and/or radiochemotherapy. A global analysis of the protein expression pattern was performed to identify radiation-responsive proteins in MCF-7 breast cancer cells using 2D-PAGE coupled with MALDI-TOF-MS. When MCF-7 cells were exposed to ionizing radiation (IR) such as γ-rays, eight proteins (GH2,...
