Description
Whether the human tumor virus, Epstein-Barr virus (EBV) promotes breast cancers remains controversial and a potential mechanism has remained elusive. Here we show EBV can infect primary mammary epithelial cells (MECs) that express the attachment receptor, CD21. EBV infection leads to the expansion of early MEC progenitor cells with a stem cell phenotype and enforces a differentiation block. When MECs were implanted as xenografts, EBV infection cooperated with activated Ras and accelerated the formation of breast cancer. Infection in EBV-related tumors was of a latency type II pattern, including expression of latent membrane proteins 1 (LMP1) and 2 (LMP2), similar to nasopharyngeal carcinoma (NPC). A human gene expression signature for EBVness was generated based on the RNA expression profile of the EBV infected primary mammary epithelial cells, tumors. This was signature associated with high grade (40 vs 13.5%) estrogen-receptor-negative status (31.8 vs. 10.5%, p53 mutation (37.5 vs 14.5%) and poor survival. In 11/33 (33%) of tumors positive for EBVness EBV-DNA was found in tumor cells by fluorescent in situ hybridization for the viral LMP1 and BXLF2 genes, while only 4/36 (11%) of EBVness-negative tumors tested positive for EBV DNA. An analysis of the TCGA breast cancer data revealed a correlation of EBVness with presence of the APOBEC mutational signatures consistent with past viral infection. We conclude that a contribution of EBV to breast cancer etiology via a hit-and-run mechanism is plausible, in which EBV infection predisposes mammary epithelial cells to malignant transformation, but is not required for the maintenance of the malignant phenotype.

Description
The goal of this study was to investigate and correlate differential methylation and expression in cells from the target organ in non-infectious granulomatous lung diseases, specifically sarcoidosis and chronic beryllium disease (CBD). To that end, cells were collected from patients via bronchoalveolar lavage (BAL), and extracted nucleic acids were hybridized to genome-wide arrays.

Description
Rationale: The fibrosing idiopathic interstitial pneumonias (IIPs) are classified based on clinical, radiographic, and pathologic criteria. The separation into phenotypic subgroups is useful in predicting outcome and therapeutic strategy; however a large degree of ambiguity remains. Gene expression profiling may contribute to traditional criteria in IIPs by characterizing the dynamic biology that more accurately distinguishes subtypes of these diseases or their prognoses.

Description
We used RNA-seq as a method of next generation sequencing (NGS) to identify RIPK1 dependent inflammatory mediators and pathways in LPS injected mice. Overall design: Mice were divided intro 3 groups - control (n=2), LPS (n=2) and LPS/Nec-1 (n=2). BM cells were isolated by FACS as described for qPCR analysis. Total RNAs were isolated using Qiagen RNeasy kit according to the manufacturer's protocol
