Background
Distinct roles of the Gcn5 histone acetyltransferase revealed during transient stress-induced reprogramming of the genome.
Treatment
View SamplesThe data provide information expression profile in yeast for 5 different physioloigcal conditions during stress adpatation and stress recovery (normal growth, during stress adaptation, after stress adaptation, under stress recovery, after stress recovery) in yeast. The purpose of the study is to understand how histone acetyltransferase HATs (Gcn5) apply it is function in gene regulation by changing global or local histone acetylation level under different physiological conditions.

View SamplesAnalysis of histone acetyl transferases (HATs) from the MYST and GNAT families in S. pombe to identify functional differences or overlap with regard to gene expression. Mutations were made to Elp3 and Gcn5 (GNAT family), and to Mst2 (MYST family). Mutants showed distinct phenotypes which were repressed or enhanced by mutant combinations.

View SamplesLight and brassinosteroids (BRs) have been proved to be crucial in regulating plant growth and development, however, the mechanism of how they synergistically function is still largely unknown. To explore the underlying mechanisms in photomorphogenesis, genome-wide analyses were carried out through examining the gene expressions of the dark-grown WT or BR biosynthesis-defective mutant det2 seedlings in presence of light stimuli, or exogenous Brassinolide (BL). Results showed that BR deficiency stimulates, while BL treatment suppresses, the expressions of light responsive genes and photomorphogenesis, revealing the negative effects of BR in photomorphogenesis. This is consistent with that genes involved in cell wall modification and cellular metabolism were specifically modulated by BL during dark-light transition, and altered expressions of genes related to energy utilization. Further analysis revealed that hormone biosynthesis and signaling related genes, especially those of auxin, were altered under BL treatment or light stimuli, indicating that BR may modulate photomorphogenesis through synergetic regulation with other hormones. Additionally, suppressed ubiquitin-cycle pathway during light-dark transition hinted the presence of a complicated network among light, hormone and protein degradation. The study provides the direct evidence of BR effects in photomorphogenesis and identified the genes involved in BR and light signaling pathway, which will help to elucidate the molecular mechanism of plant photomorphogenesis.

View SamplesSel1L is an adaptor protein for the E3 ligase Hrd1 in the endoplasmic reticulum-associated degradation (ERAD), but its physiological role in a cell-type-specific manner remains unclear. Here we show that mice with adipocyte-specific Sel1L deficiency are resistant to diet-induced obesity and exhibit postprandial hypertriglyceridemia. Mechanistically, our data demonstrate a critical requirement of Sel1L for the secretion of lipoprotein lipase (LPL), independently of its role in Hrd1-mediated ERAD and ER homeostasis. Further biochemical analyses revealed that Sel1L physically interacts and stabilizes the LPL maturation complex consisted of LPL and lipase-maturation factor 1 (LMF1). In the absence of Sel1L, LPL is retained in the ER and prone to the formation of protein aggregates, which are degraded by autophagy-mediated degradation. The Sel1L-mediated control of LPL secretion is seen in other LPL-expressing cell types as well such as cardiac muscle and macrophages. Thus, our study reports a novel role of Sel1L in LPL secretion and systemic lipid metabolism.

View SamplesPsoriasis is a chronic inflammatory skin disease related to immune, whose complexity of molecular mechanisms is still not fully clear. RNA sequencing has been widely applied in various fields including biological medicine. According to the bioinformatics analysis of differential genes, biomarkers and drug targets have been discovered for the diagnosis and treatment of diseases. Besides, the pathological mechanisms of disease and functions of gene can be evaluated. In the present study, we report the application of RNA sequencing in skin tissues from psoriatic and healthy persons. By obtaining 2139 differential expressed genes (DEGs), 208 significantly differential GO terms and 44 significantly differential pathways were generated. We found that the functions of DEGs were mainly related to cell cycle, inflammatory, virus, immune response and metabolic process.The major pathways included cytokine-cytokine receptor interaction, Toll-like receptor signaling pathway, chemokine signaling pathway, cell cycle, metabolic pathways, ribosome, peroxisome, steroid biosynthesis and biosynthesis of unsaturated fatty acids. Furthermore, co-expression network was constructed to identify core genes and relations between genes. we considered genes with high values of degree and k-core difference in the co-expression network as core genes, such as IFNG, IL26, TLR3, PRKCQ, TLR4, CD274, CDK1 and IL17A. We chose CD274, an important immune checkpoint, to evaluate its regulatory mechanisms. Candidate genes related to CD274 were evaluated by the co-expression network analysis, and the relations between CD274 and candidate genes were validated in epidermal keratinocytes. Finally, IFNG and CDK1 inhibitor (indirubin) were found increasing the expression levels of CD274. In addition, indirubin was confirmed to attenuate mouse psoriasis-like skin lesion with the mechanisms related to CD274. In conclusion, this study provides us a comprehensive transcriptome analysis method on psoriasis to identify core genes and explore the important regulatory functions of genes. Overall design: Nine normal skins from healthy volunteers and 18 lesional skins from patients with psoriasis vulgaris were obtained for RNA sequencing
