Description
Cellular replicative senescence, a state of permanent cell-cycle arrest that occurs following an extended period of cell division in culture, has been linked to organismal aging, tissue repair and tumorigenesis. In this study, we comparatively investigated the global lipid profiles and mRNA content of proliferating and senescent-state BJ fibroblast cells. We found that both the expression levels of lipid-regulating genes, as well as the abundance of specific lipid families, are actively regulated. We further found that 19 polyunsaturated triacylglycerol species showed the most prominent changes during replicative senescence. We argue that diversion of polyunsaturated fatty acids to glycerolipid biosynthesis could be responsible for the accumulation of specific triacylglycerols. This, in turn, could be one of the cellular mechanisms to prevent lipotoxicity under increased oxidative stress conditions observed during replicative senescence. Collectively, our results place regulation of specific lipid species to a central role during replicative senescence. Overall design: We sequence total RNA from 3 early PD and 3 senesent human BJ cell lines to detect the expressional differences between early PD and senescent cells.

Description
Comparative RNA seq analysis of WT and global p73KO Mouse Tracheal Epithelial Cell (MTECs) during the course of their differentiation (Air-Liquid Interface ALI D0, D4, D7, D14) aimed to determine the role of p73 in motile multiciliogenesis. Overall design: Three independent biological replicates of murine primary airway epithelial cell cultures (MTECs) from wild type and global p73KO mice were differentiated under air-liquid interface (ALI) conditions and harvested at Day 0, Day 4 , Day 7 and Day 14 post ALI.

Description
After inactivation of Hoxa5 at postnatal days (P)1-P4, we established RNA-seq profiling with RNA extracted from P21 brainstem of tamoxifen-treated Hoxa5flox/flox;CMV-CreERT2+/- (Hoxa5 cKO) pups and tamoxifen-treated Hoxa5flox/flox;CMV-CreERT2-/-(Hoxa5 control) pups Overall design: To explore HOXA5 downstream target genes in the postnatal brainstem, we carried out transcriptomic analyses by RNA-Seq using a model of postnatal Hoxa5 loss-of-function. We induced Hoxa5 inactivation after birth (P1 to P4) using the tamoxifen-inducible CMV-CreERT2 mice and conditional Hoxa5 floxed allele mice (Hoxa5flox). RNA was extracted from the brainstem of P21 tamoxifen-treated Hoxa5flox/flox;CMV-CreERT2+/- pups and from tamoxifen-treated Hoxa5flox/flox;CMV-CreERT2-/- littermates (see extract protocol).

In this report, Tompkins et al describe the derivation, differentiation stage-specific purification, and genome-wide analysis of cardiomyocytes derived from hESCs. Key features of the molecular programs that define human cardiac muscle cell differentiation were described and researchers observed that cells may harbor epigenetic DNA methylation “memories” that reflect the gene activation history of important developmental genes. Overall design: For RNA-seq. Cardiomyocyte differentiation from human embryonic stem cells (H7). 11 time point pilot time series. D3 and D4 samples FACS sorted for primitive and cardiac mesoderm isolation, respectively. Data from negatives sorts (minus) included as well.

Description
Progressive failure of insulin-producing beta cells is the central event leading to diabetes, yet the signalling networks controlling beta cell fate remain poorly understood. Here we show that SRp55, a splicing factor regulated by the diabetes susceptibility gene GLIS3, has a major role in maintaining function and survival of human beta cells. RNA-seq analysis revealed that SRp55 regulates the splicing of genes involved in cell survival and death, insulin secretion and JNK signalling. Specifically, SRp55-mediated splicing changes modulate the function of the pro-apoptotic proteins BIM and BAX, JNK signalling and endoplasmic reticulum stress, explaining why SRp55 depletion triggers beta cell apoptosis. Furthermore, SRp55 depletion inhibits beta cell mitochondrial function, explaining the observed decrease in insulin release. These data unveil a novel layer of regulation of human beta cell function and survival, namely alternative splicing modulated by key splicing regulators such as SRp55 that may crosstalk with candidate genes for diabetes. Overall design: Five independent preparations of EndoC-ßH1 cells exposed to control (siCTL) or SRp55 (siSR#2) siRNAs
