Description
RANK-positive and RANK-negative luminal progenitor cells were isolated by FACS from histologically normal human breast tissue from wild-type human donors. RNA-seq gene expression profiling was used to find differentially expressed genes between the RANK-positive and RANK-negative cell populations. Overall design: Cells were isolated from 4 human patients. A paired analysis was used to compare RANK-positive and RANK-negative cells within patients.

Description
BRCA1, a well-known breast and ovarian cancer susceptibility gene with multiple interacting partners, is predicted to have diverse biological functions. However, to date its only well-established role is in the repair of damaged DNA and cell cycle regulation. In this regard, the etiopathological study of low penetrant variants of BRCA1 provides an opportunity to uncover its other physiologically important functions. Using this rationale, we studied the R1699Q variant of BRCA1, a potentially moderate risk variant, and found that it does not impair DNA damage repair but abrogates the repression of miR-155, a bona fide oncomir. We further show that in the absence of functional BRCA1, miR-155 is up-regulated in BRCA1-deficient mouse mammary epithelial cells, human and mouse BRCA1-deficienct breast tumor cell lines as well as tumors. Mechanistically, we found that BRCA1 represses miR-155 expression via its association with HDAC2, which deacetylates H2A and H3 on the miR-155 promoter. Finally, we show that over-expression of miR-155 accelerates whereas the knockdown of miR-155 attenuates the growth of tumor cell lines in vivo. Taken together, our findings demonstrate a new mode of tumor suppression by BRCA1 and reveal miR-155 as a potential therapeutic target for BRCA1-deficient tumors.

Description
Microglia are the resident myeloid-lineage cells in the central nervous system. Despite myriad observations of microglia associated with various tissue pathologies in degenerative disease, their function in and contributions to the pathophysiological processes remain unclear. It is particularly uncertain whether microglia act harmfully to contribute to worsening of degeneration, act beneficially to combat disease-related dysfunction, or perform functions that result in both outcomes. In this dataset, we report RNA sequencing results from mice that undergo inducible ALS/FTLD-like degeneration and subsequent recovery. The goals were to identify whether microglia show transcriptional signatures commensurate with the disease stage or if they remain constant throughout. Additionally, we sought to understand whether there was a particular transcriptional or functional signature associated with functional recovery in the mice. The latter could lead to an understanding of how microglia may be targeted to combat disease and enhance recovery following or during degeneration. Overall design: mRNA profiles from microglia sorted from whole-spinal cord taken from doxycycline (DOX) inducible NEFH-tTa/tetO-208-hTDP43 (rNLS8, (+/+)) mice. In these mice, removal of doxycycline from the diet (DOX-OFF) induces transgenic expression and degeneration and reintroduction (DOX-ON) suppresses expression and enables recovery. We report profiles from rNLS8 mice that were DOX-OFF for 2 weeks (N=8) or 6 weeks (N=7), or DOX-OFF for 6 weeks followed by DOX-ON for 1 week (N=9). We also report profiles from control samples that include: rNLS8 mice that were DOX-ON for 6 weeks (N = 6) as asymptomatic genetic controls and WT (-/-) littermates that were DOX-OFF for 2 weeks (N=4), 6 weeks (N=1), or DOX-OFF for 6 weeks followed by 1 week DOX-ON (N=3) as asymptomatic doxycycline controls.

Description
The enzymes of the poly-ADP-ribose polymerase (PARP) super-family control many relevant cellular processes, but a precise understanding of their activities in different physiological or disease contexts is largely incomplete. We found that transcription of several PARP genes was dynamically regulated upon macrophage activation by several inflammatory stimuli. Specifically, PARP14 was strongly induced by endotoxin stimulation and translocated to the nucleus in stimulated cells. Quantitative mass spectrometry analysis showed that PARP14 bound to a group of interferon-stimulated gene (ISG)-encoded proteins, most with an unknown function, and it was required for their nuclear accumulation. Moreover, PARP14 depletion attenuated transcription of primary antiviral response genes regulated by the transcription factor IRF3, including Ifnb1, thus reducing IFNß production and activation of ISGs involved in the secondary antiviral response. Overall, these data hint at a role of PARP14 in the control of antimicrobial responses and specifically in nuclear activities of a subgroup of ISG-encoded proteins. Overall design: mRNA sequencing of differentially expressed genes in PARP14 WT and KO RAW 264.7 cells, upon: no treatment, LPS, Jak inhibitor or LPS plus Jak inhibitor treatment.
