Description
Genome stability relies on epigenetic mechanisms that enforce repression of endogenous retroviruses (ERVs). Current evidence suggests that distinct chromatin-based mechanisms repress ERVs in cells of embryonic origin (histone methylation-dominant) versus more differentiated cells (DNA methylation-dominant). However, the latter aspect of this model has not been tested. Remarkably, and in contrast to the prevailing model, we find that repressive histone methylation catalyzed by the enzyme SETDB1 is critical for suppression of specific ERV families and exogenous retroviruses in committed B-lineage cells from adult mice. The profile of ERV activation in SETDB1-deficient B cells is distinct from that observed in corresponding embryonic tissues, despite the loss of repressive chromatin modifications at all ERVs. We provide evidence that, upon loss of SETDB1, ERVs are activated in a lineage-specific manner depending on the set of transcription factors available to target proviral regulatory elements. These findings have important implications for genome stability in somatic cells, as well as the interface between epigenetic repression and viral latency.

Description
Multiple myeloma is a fatal hematological malignancy. In order to develop effective therapeutic approaches, it is critical to understand the pathogenesis of myeloma. The Radl 5T model of multiple myeloma is a clinically relevant murine model where myeloma spontaneously occurs in aged, in-bred C57BlKalwRij mice and can be propagated by intravenous inoculation of 5T myeloma cells into mice of the same strain. Importantly inoculation of 5T myeloma cells into C57Bl6 mice does not result in myeloma, demonstrating that the bone marrow (BM) microenvironment of the C57BlKalwRij strain provides a unique and permissive milieu for myeloma development. We hypothesized that cells of the BM microenvironment may provide essential stimuli for the development of multiple myeloma in vivo. We aim to determine the differences in expression within the bone marrow of C57Bl/KalwRij mice.

- Affymetrix Rat Gene 1.0 ST Array (ragene10st)
Description
Nr4a1 deficient rats (Nr4a1-/-) were developed using the fawn hooded hypertensive rat (FHH), which provided a genetic background susceptible to kidney injury. Both groups of animals were evaluated for blood pressure, proteinuria, renal function, and whole transcriptome gene pathway changes. Gene expression profiling was performed at week 8, 16, and 24 using kidney from FHH and Nr4a1-/- rats. To identify differentially expressed gene between FHH and Nr4a1-/- two statistical methods were utilized: (1) FWER (family-wise error rate) procedure, p<0.05 and fold-change 1.2 or greater; and/or (2) Benjamani and Hochberg FDR (false discovery rate) using p<0.05, and fold-change 1.2 or greater. Two-way ANOVA using a p<0.01 or lower was performed to identify strain X time interaction effects between groups. Gene networks and functional analysis were evaluated through the use of Ingenuity Pathways Analysis .

Description
We recently developed a new model of renal agenesis [i.e., the heterogeneous stock derived model of unilateral renal agenesis, (HSRA)]. The HSRA model consistently exhibits unilateral renal agenesis ranging from 50-75% in each generation and is characterized by low nephron number, early kidney hypertrophy, and an inherent susceptibility to develop significant kidney injury and decline in renal function with age.
