Description
The Long Evans/orl (LE/orl) rat is an animal model of inherited undescended testis (UDT). To explore genetic mechanisms of UDT, we studied differential gene expression in LE/orl and LE wild type (LE/wt) fetal gubernaculum and testis.

Description
A comparative analysis of gene expression of CD4+ EGFP+ Nrp1+ (tTreg, thymus-derived Treg), CD4+ EGFP+ Nrp1- (pTreg, peripherally-derived Treg) and CD4+ EGFP- (Tconv, conventional T cell) in CD28-/- Foxp3EGFP and Foxp3EGFP mice. Overall design: Nrp1+ Treg (tTreg), Nrp1- Treg (pTreg) and Tconv were sorted from Foxp3EGFP and CD28-/-Foxp3EGFP mice. Total RNAs were extracted from whole samples and analyzed by RNA-seq.

Description
This study was designed to provide additional insight into testicular hormone production and responsiveness in the orl strain and complement ongoing efforts to characterize the genetic basis of cryptorchidism in this isolated rat colony.
Publication Title
Cryptorchidism in the orl rat is associated with muscle patterning defects in the fetal gubernaculum and altered hormonal signaling.

Description
The specialized corneal epithelium requires differentiated properties, specific for its role at the anterior surface of the eye, thus tight maintenance of the differentiated qualities of the corneal epithelial is essential. Our studies have focused on pinin (PNN), an exon junction component (EJC) that has dramatic implications on corneal epithelial cell differentiation and may act as a stabilizer of the corneal epithelial cell phenotype. Our studies revealed that PNN is involved in both transcriptional repression complexes and the spliceosomal complexes, placing PNN at the fulcrum between chromatin and mRNA splicing. Transcriptome analysis of PNN-knockdown cells revealed clear and reproducible alterations in transcript profiles and splicing patterns of a subset of genes that would significantly impact the epithelial cell phenotype. Here, we further investigate PNN’s role in the regulation of gene expression and alternative splicing (AS) in a corneal epithelial context. We used human corneal epithelial cells (HCET cells) that carry doxycycline-inducible PNN-knockdown shRNA vector and performed RNA-seq to determine differential gene expression and differential AS events. Multiple genes and AS events were identified as differentially expressed between PNN-knockdown and controls cells. Genes up-regulated by PNN-knockdown included a large proportion of genes that are associated with processes associated with enhanced cell migration and ECM remodeling including: MMPs, ADAMs, HAS2, LAMA3, CXCRs and UNC5C. Genes down-regulated in response to PNN depletion included: IGFBP5. FGD3, FGFR2, PAX6, RARG and SOX10. AS events in PNN compared to controls was also more likely to be detected, and uregulated in PNN-knockdowns. In particular, 60% of exon skipping events detected in only one condition were detected in PNN-knockdowns and of the shared exon skipping events, 92% of those differentially expressed were more frequent in the PNN-knockdown. This suggests that in the absence of PNN the epithelial cells are dramatically transformed in the amount and composition of isoforms and that PNN plays a crucial role in the selection of which isoforms differentiating cells produce. Many of the genes affected by PNN-knockdown are known to affect epithelial phenotype. This window into the complexity of RNA splicing in the corneal epithelium implies that PNN exerts broad influence over the regulation and maintenance of epithelial cell phenotype. Overall design: We used HCET cells that carry doxycycline-inducible PNN knockdown shRNA vector and performed RNA-seq to determine differential gene expression and differential alternative splicing events.

- Affymetrix Mouse Gene 1.0 ST Array (mogene10st)
Description
The oviducts play a critical role in gamete and embryo transport, as well as supporting fertilization and early embryo development. Progesterone receptor (PGR) is a transcription factor highly expressed in oviductal cells, while its activating ligand, progesterone (P4), surges to peak levels as ovulation approaches. P4 is known to regulate oviduct cilia beating and muscular contractions in vitro, but how PGR may mediate this in vivo is poorly understood. We used PGR-knockout (PRKO) mice to determine how PGR regulates oviductal function during the periovulatory period, in particular oviductal transport and embryo support.

Description
Ovulation requires sequential molecular events and structural remodeling in the ovarian follicle for the successful release of a mature oocyte capable of being fertilised. Critical to this process is progesterone receptor (PGR), a transcription factor highly yet transiently expressed in granulosa cells of preovulatory follicles. Progesterone receptor knockout (PRKO) mice are anovulatory, with a specific and complete defect in follicle rupture. Therefore, this model was used to examine the critical molecular and biochemical mechanisms necessary for successful ovulation.

Description
Side population (SP) cells isolated from limbal and conjunctival epithelia derive from cells that are slow cycling in vivo, a known feature of tissue stem cells. The purpose of this study was to define the molecular signature of the conjunctival side population cells by global differential gene expression to identify markers and signaling pathways associated with this cell phenotype.
