Description
The primary spermatogonial stem cells (SSCs), which arise from gonocytes during neonatal development, serve as a foundational self-renewing reservoir to ensure continuous production of spermatozoa throughout adulthood. The transformation of gonocytes into SSCs takes place in a niche established by Sertoli cells. To date, the factors that guide Sertoli cells to establish the initial stem cell niche remain largely unknown. Using Sertoli cell-specific Arid4b knockout (Arid4bSCKO) mice, we demonstrated that ablation of ARID4B resulted in failure to establish a niche for the SSC formation. We performed RNA-Seq analysis to examine the gene expression profile of the Arid4bSCKO testes in comparison with that of control testes. Overall design: We extracted RNA from testes of the control and Arid4bSCKO mice at postnatal day 1.5 of age. Each genotypic group consisted of three pools of testes, and each pool contained four testes. Purified RNA was processed for RNA-Seq analysis using Illumina HiSeq 2500.

Description
Puberty unmasks or accelerates nephropathies, including the nephropathy of diabetes mellitus (DM). A number of cellular systems implicated in the kidney disease of DM interweave, forming an interdependent functional web. We performed focused microarray analysis to test the hypothesis that one or more genes in the transforming growth factor beta (TGF-) signaling system would be differentially regulated in male rats depending on the age of onset of DM.

Description
RNA polymerase (pol) III transcribes a variety of small untranslated RNAs that are involved in essential cellular processes that include transcription, RNA processing, and translation. RNA pol III and its components are altered in various human developmental disorders, yet their roles in cell fate determination and development are poorly understood. Here we demonstrate that Maf1, a transcriptional repressor, promotes induction of mouse embryonic stem cells into mesoderm and their terminal differentiation into adipocytes. Reduced Maf1 expression in preadipocytes impairs adipogenesis while ectopic Maf1 expression in Maf1-/- deficient cells enhances differentiation. RNA pol III repression by either chemical inhibition or knockdown of Brf1, promotes adipogenesis. Altered RNA pol III-dependent transcription produces select changes in RNA pol II-derived transcripts with a significant enrichment of adipogenic gene signatures. Furthermore, RNA pol III-mediated transcription positively regulates long non-coding RNA H19 and Wnt6 expression, established adipogenesis inhibitors. Together, these studies reveal an important and unexpected function for RNA pol III-mediated transcription and Maf1 in mesoderm induction and cellular differentiation. Overall design: Gene expression profiling by RNA-seq at two time points (day 0: before differentiation, day 2: two days after differentiation) with knockdown by shRNA of Maf1 and Brf1, respectively, and RNA Pol III inhibitor, ML-60218, treatment compare to the control (empty shRNA vector) in 3T3-L1 cells.
