Description
Accumulation of activated cardiac fibroblasts plays a key role in heart failure progression. These cells deposit excessive extracellular matrix that leads to mechanical stiffness, myocyte uncoupling and ischemia. To investigate whether two developmentally distinct cardiac fibroblast populations exhibit distinct expression profiles in response to cardiac injury, and therefore might necessitate distinct therapeutic targeting, we performed microarray analysis on FACS sorted cells. Tie2cre lineage traced CFs, non Tie2cre lineage traced cardiac fibroblasts and endothelial cells were isolated from left ventricle of SHAM operated and banded hearts at the onset of fibrosis, one week after surgery.

Description
The recently proposed exozyme hypothesis posits that subunits of the RNA processing exosome assemble into structurally distinct protein complexes that function in disparate cellular compartments and RNA metabolic pathways. Here, in a genetic test of this hypothesis, we examine the role of Dis3 -- an essential polypeptide with endo- and 3'' to 5'' exo-ribonuclease activity -- in cell cycle progression. We present several lines of evidence that perturbation of DIS3 affects microtubule (MT) localization and structure in Saccharomyces cerevisiae. Cells with a DIS3 mutation: (i) accumulate anaphase and pre-anaphase mitotic spindles; (ii) exhibit spindles that are mis-oriented and displaced from the bud neck; (iii) harbor elongated spindle-associated astral MTs; (iv) have an increased G1 astral MT length and number; and (v) are hypersensitive to MT poisons. Mutations in the core exosome genes RRP4 and MTR3 and the exosome cofactor gene MTR4 -- but not other exosome subunit gene mutants -- also elicit MT phenotypes. RNA deep sequencing analysis (RNA-seq) shows broad changes in the levels of cell cycle- and microtubule-related transcripts in mutant strains. Collectively, the different mitotic phenotypes and distinct sets of mRNAs affected by the exosome subunit and cofactor mutants studied here suggest that Dis3 has a core exosome-independent role(s) in cell cycle progression. These observations are consistent with the predictions of the exozyme hypothesis and also suggest an evolutionarily conserved role for Dis3 in linking RNA metabolism, MTs, and mitotic progression. Overall design: RNA-seq analysis of total RNA harvested from WT, mtr3-1, mtr4-1, and Dis3^mtr (rrp44-1/mtr17-1) Saccharomyces cerevisiae strains after a temperature shift.

Description
PRDM16 is a strong activator of brown fat-specific genes, while also a repressor of white fat and muscle-specific genes. We asked what other pathways are regulated by PRDM16 in adipocytes that may be critical for brown and/or beige adipogenesis. Using microarray, we found PRDM16 also represses type I Interferon-stimulated genes (ISGs) in adipocytes.
