Affymetrix Yeast Genome S98 Array (ygs98)
Description
Global restriction of protein synthesis is a hallmark of cellular stress. Using hydrogen peroxide, we monitor the transcript level and also the translation status for each RNA using cycloheximide to freeze elongating ribosomes. Polyribosome fractionation of cell extracts was used to separate highly translated and poorly translated mRNAs that were then separately analysed.

Description
One common form of translational control is mediated by proteins that bind to the mRNA 5' cap-binding protein eIF4E. These proteins are collectively called 4E binding proteins (4EBPs). Saccharomyces cerevisiae possesses two 4EBPs that are encoded by non-essential genes called CAF20 and EAP1. To determine the impact of gene deletion on gene expression, we monitored the transcript level and also the translation status for each RNA using cycloheximide to freeze elongating ribosomes in wild-type, caf20 and eap1 cells. Polyribosome fractionation of cell extracts was used to separate highly translated and poorly translated mRNAs that were then separately analyzed.

Identifying eIF4E-binding protein translationally-controlled transcripts reveals links to mRNAs bound by specific PUF proteins.

Description
This study was designed to define erythropoietin (EPO) regulated genes in murine bone marrow erythroid progenitor cells at two stages of development, designated E1, and E2. E1 cells correspond to CFUe- like progenitors, while E2 cells are proerythroblasts.

Description
Long noncoding RNAs (lncRNAs) are emerging as powerful regulators of adipocyte differentiation and gene expression. However, their physiological role in adipose tissue biology and systemic energy metabolism has not been established. Here we show that adipose tissue expression of Blnc1, a conserved lncRNA regulator of thermogenic genes, is highly induced in obese mice. Fat-specific inactivation of Blnc1 impairs cold-induced thermogenesis and browning, exacerbates obesity-associated brown fat whitening, and worsens adipose tissue inflammation and fibrosis, leading to more severe insulin resistance and hepatic steatosis. On the contrary, transgenic expression of Blnc1 in adipose tissue elicits the opposite and beneficial metabolic effects, supporting a critical role of Blnc1 in driving adipose adaptation during obesity. Mechanistically, Blnc1 cell-autonomously attenuates proinflammatory cytokine signaling and promotes fuel storage in adipocytes through its protein partner Zbtb7b. This study illustrates a surprisingly pleiotropic and dominant role of lncRNA in driving adaptive adipose tissue remodeling and preserving metabolic health.

Description
Mice lacking TSKU exhibited elevated core body temperature and were unable to adequately suppress energy expenditure during starvation, leading to greater body weight loss. Tsku null mice were strongly resistant to diet-induced obesity and its associated metabolic disorders, including insulin resistance and hepatic steatosis. This metabolic phenotype was associated with sympathetic activation and enhanced brown fat thermogenesis. Here we used microarrays to uncover the metabolic pathways relevant to the phenotype induced by Tsku deficiency.

Description
we construct a comprehensive mouse transcriptomic BodyMap across 17 tissues of six-weeks old C57BL/6JJcl mice using RNA-seq. We find different expression patterns between protein-coding and non-coding genes. Liver and adrenal gland expressed the least complex transcriptome, whereas testis and ovary harbor more complex transcriptome than other tissues. We report a comprehensive list of tissue-specific genes across 17 tissues. Our study provides a unique resource of mouse gene-expression profiles, which is helpful for further biomedical research.

Description
To obtain a comprehensive understanding of transcriptomic reprogramming under salt stress, we performed whole genome RNA sequencing on salt-treatment soybean seedlings, on two tissues in a time-course experiment (0h, 1h, 2h, 4 h, 24h and 48h). This time series dataset enables us to identify important hubs and connection of gene expressions. We highlighted the analysis of phytohormone signaling pathways and their possible cross-talking. Gene expression regulation also controls adjustment of carbon and nitrogen metabolism. In general, the treated seedlings had turned off the photosynthetic mechanism and enhanced sugar catabolism to provide energy for survival. Primary nitrogen assimilation was shut down while re-distribution of nitrogen resources was activated. Genes for other protective mechanisms were also induced, including structural modification, ion-sequestering, and scavenging of reactive oxygen species.

Description
Calcium acts as a universal second messenger to regulate gene expression in both developmental processes and responses to environmental stresses. Previous studies showed that a number of stimuli can induce calcium increases in the cytoplasm and nucleus, independently. However, the gene expression network deciphering [Ca2+]cyt and/or [Ca2+]nuc signaling pathway remain obscure.
