Description
Loss of function of the tumor suppressor BRCA1 (Breast Cancer 1) protein is responsible for numerous familial and sporadic breast cancers. We previously identified PABP1 as a novel BRCA1 partner and showed that BRCA1 modulates translation through its interaction with PABP1. We showed that the global translation was diminished in BRCA1-depleted cells and increased in BRCA1-overexpressing cells. Our findings raised the question whether BRCA1 affects translation of all cytoplasmic cellular mRNAs or whether it specifically targets a subset of mRNAs.

Description
Hutchinson-Gilford progeria syndrome (HGPS) is a premature aging disease that is frequently caused by a de novo point mutation at position 1824 in LMNA. This mutation activates a cryptic splice donor site in exon 11, and leads to an in-frame deletion within the prelamin A mRNA and the production of a dominant negative lamin A protein, known as progerin. Here we show that HGPS cells experience genome-wide alterations in patterns of H3K27me3 deposition, changes in the associations of genomic loci with nuclear lamin A/C, and, at late passages, genome-wide loss of spatial compartmentalization of active and inactive chromatin domains that characterizes chromosome folding in normal cells. We further demonstrate that the H3K27me3 changes associate with gene expression alterations in HGPS cells. Our results support a model that the accumulation of progerin in the nuclear lamina leads to altered H3K27me3 marks in heterochromatin, possibly through the down-regulation of EZH2, and disrupts heterochromatin-lamina interactions. These changes may then lead to the genomic disorganization and changes in transcriptional regulation we observe in HGPS fibroblasts.

Description
Diffuse intrinsic pontine glioma (DIPG) is an incurable pediatric brain tumor, resulting in the death of 200-300 children each year in the United States. Recently it was discovered that approximately 25% of all DIPG cases harbor activating mutations in ACVR1, a gene that encodes Activin A receptor (ALK2), a receptor in the bone morphogenetic protein (BMP) pathway, and that DIPGs with ALK2 mutations commonly harbor an H3.1K27M mutation. Herein, we used the RCAS/TVA retroviral system to study the effects of ACVR1 mutations and H3.1K27M on DIPG pathogenesis. In vitro expression of R206H ACVR1 with and without H3.1K27M in nestin-expressing brainstem progenitors resulted in upregulation of mesenchymal markers and gene set enrichment analysis (GSEA) revealed Stat3 pathway activation. Neonatal expression of ACVR1 R206H or G328V in combination with H3.1K27M and p53 deletion in nestin-expressing brainstem progenitors induced glioma-like lesions expressing mesenchymal markers with Stat3 activation but was not sufficient for full gliomagenesis. In combination with platelet-derived growth factor A (PDGFA) signaling, ACVR1 R206H and H3.1K27M significantly decreased survival and increased tumor incidence. We demonstrate that targeting the BMP signaling pathway may be an effective therapeutic strategy to treat ACVR1 R206H mutant DIPGs. Exogenous Noggin expression at tumor initiation significantly increased tumor latency and treatment of ACVR1 R206H mutant murine DIPGs with LDN212854, an ACVR1 inhibitor, significantly prolonged their survival. We confirm relevance of our model to the human disease as human DIPG models with ACVR1 mutations were also sensitive to treatment with LDN212854 in vitro. Altogether, our studies demonstrate that ACVR1 R206H and H3.1K27M promote tumor initiation, accelerate gliomagenesis, promote a mesenchymal profile in part due to Stat3 activation, and identify LDN212854 as a promising compound to treat children with DIPG. Overall design: We use RNAseq to study the transcriptomal effects of ACVR1 WT or R206H ACVR1 mutation alone and in combination with H3.1K27M mutation on murine nestin-expressing brainstem progenitors at P3-5 (using RCAS/TVA). Key findings were validated by Real-Time PCR.

We investigated transcriptional responses of different lung macrophage lineages during M.tuberculosis infection by RNAseq. Our data revealed that different lineages of macrophages respond differentially to M.Tuberculosis infection. Overall design: Alveolar macrophage (AM) and interstitial macrophages (IM) with or without Mtb were FACS-sorted from Mtb infected mice for RNAseq.
