Project description:The TNF superfamily is large, including TNF ligands (n = 19) and TNF receptors (n = 29),as determined following the completion of large-scale sequencing of the human and mouse genomes. These members not only function in immune cells but are also involved in respiratory and intestinal diseases, and some members may act as a double-edged sword. Tumor necrosis factor-like cytokine 1A (TL1A, also known as TNFSF15) is the only known death receptor 3 (DR3, also known as TNFRSF25) ligand (Meylan et al., 2011). The TL1A/DR3 axis plays a role in the regulation of intestinal immunity and fibrosis (Valatas et al., 2019), asthma airway remodeling (Zhang et al., 2022; Herro et al., 2010), and other autoimmune and inflammatory diseases (Herro et al., 2021), exacerbating disease progression. However, some researchers have proposed that the TL1A/DR3 axis has a protective role in some disease models. A novel role for TL1A/DR3 in protection against intestinal injury was reported by Jia et al (Jia et al., 2016). Yang et al. revealed a protective effect of TL1A against intracerebral hemorrhage-induced secondary brain injury and infection (Yang et al., 2021). In addition, TL1A maintains the blood–retinal barrier by modulating SHP-1-Src-VE-cadherin signaling in diabetic retinopathy, as verified by Li et al (Li et al., 2021). However, the role of TL1A/DR3 in ARDS has not been explored.

Project description:While our earlier microarray analysis identified a number of possible candidate genes, which may be involved in OsNOA1 function (Yang et al., 2011a), a complementary study of the rice proteome profiles under the same condition has the potential to yield new insights into the biological functions of NOA1 and molecular mechanism of NOA1 associated regulation. In this study, we utilized previously-generated OsNOA1 RNAi lines (Yang et al., 2011a) and newly-generated OsNOA1 overexpression lines to further investigate the function and mechanism of NOA1 in rice. Here we report the proteome changes which include important candidate proteins involved in chloroplast ribosome biogenesis and several classes of proteins with significant changes in response to various levels of OsNOA1 under two different temperature conditions. Our results suggest that OsNOA1 can function in a threshold-dependent manner to regulate the biosynthesis of chloroplast proteins in rice at lower temperatures, and this regulation may be achieved via interactions between NOA1 and chloroplast ribosomes.
Project description:A robust set of CNS transcript changes was defined by comparing microarray data that describe the injury response of the rat retina [Vazquez-Chona et al., IOVS 2004; GSE1001], brain [Matzilevich et al., J Neurosci Res 2002; GSE1911], and spinal cord [Di Giovanni et al., Ann Neurol 2003; GDS63]. We determined the CNS injury genes that were expressed in cultured astrocytes from rat cortex [GSM34300] and from human optic nerve head [Yang et al., Physiol Genomics 2004; GDS532]. Keywords: other
Project description:Mitochondrial biogenesis requires precise regulation of both mitochondrial-encoded and nuclear-encoded genes. Nuclear receptor Nur77 is known to regulate mitochondrial metabolism in macrophages and skeletal muscle cells. Here, we compared genome-wide Nur77 binding site and target gene expression in these two cell types, which revealed conserved roles for this nuclear receptor in the regulation of nuclear-encoded mitochondrial ribosomal proteins (MRP) and enrichment of motifs for the transcription factor Yin-Yang 1 (YY1). We show that Nur77 and YY1 interact, that YY1 increases Nur77 activity, and that their binding sites are co-enriched at MRP gene loci. Nur77 and YY1 co-expression synergistically increases mitochondrial abundance and activity in macrophages but not skeletal muscle. As such, we identify a macrophage-specific Nur77-YY1 interaction that enhances mitochondrial metabolism.
