Affymetrix Rat Expression 230A Array (rae230a)
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.
Publication Title
Altered expression of muscle- and cytoskeleton-related genes in a rat strain with inherited cryptorchidism.

Description
Insl3 is a testis-derived hormone that induces growth and differentiation of the fetal gubernaculum. The goal of this study was to identify genes showing altered expression in fetal gubernaculum following Insl3 exposure.
Publication Title
Insulin-like 3 exposure of the fetal rat gubernaculum modulates expression of genes involved in neural pathways.

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Tgif1 is a transcriptional corepressor that limits TGF responsive gene expression. TGF signaling has antiproliferative effects in several cell types, generally resulting in a G1 arrest. Mouse embryo fibroblasts (MEFs) are primary cells with limited life-span, that senesce after several passages in culture.
Publication Title
Premature senescence and increased TGFβ signaling in the absence of Tgif1.

Description
OBF1, also known as Bob.1 or OCA-B, is a B lymphocyte-specific transcription factor which coactivates Oct1 and Oct2 on B cell specific promoters. So far, the function of OBF1 has been mainly identified in late stage B cell populations. The central defect of OBF1 deficient mice is a severely reduced immune response to T cell-dependent antigens and a lack of germinal center formation in the spleen. Relatively little is known about a potential function of OBF1 in developing B cells. Here we have generated transgenic mice overexpressing OBF1 in B cells under the control of the immunoglobulin heavy chain promoter and enhancer. Surprisingly, these mice have greatly reduced numbers of follicular B cells in the periphery and have a compromised immune response. Furthermore, B cell differentiation is impaired at an early stage in the bone marrow. A first block is observed during B cell commitment and a second differentiation block is seen at the large preB2 cell stage. The cells that succeed to escape the block and to differentiate into mature B cells have post-translationally downregulated the expression of transgene, indicating that expression of OBF1 beyond the normal level early in B cell development is deleterious. Indeed ID3, which is a negative regulator of B cell differentiation, is upregulated in the EPLM and preB cells of the transgenic mice. Furthermore ID3 promoter contains an octamer site suggesting that it is a potential OBF-1 direct target gene. These results provide evidence that OBF1 expression has to be tightly regulated in early B cells to allow efficient B lymphocyte differentiation.

Description
Intraclonal subpopulations of circulating chronic lymphocytic leukemia (CLL) cells with different proliferative histories and reciprocal surface expression of CXCR4 and CD5 have been observed in the peripheral blood of CLL patients and named proliferative (PF), intermediate (IF) and resting (RF) cellular fractions. Transcriptional differences between paired intraclonal fractions confirmed their proliferative experience and further supported a linear advancement from PF to RF in the peripheral blood. Marked expression differences in intraclonal fractions suggest potential pathological and therapeutic relevance of studying intraclonal CLL fractions as compared to bulk cells.

Description
To study the role of Hlx in hematopoietic differentiation and tumorigenesis, URE cells were infected with short-hairpin-containing pSIH1-H1-copGFP lentiviral vector (System Biosciences, Mountain View, CA) containing either nucleotide sequences targeting luciferase (shControl) or HLX (shHLX). After 24hrs incubation in Iscoves modified Dulbeccos medium (IMDM) containing FBS, mIL-3, mIL-6 and mSCF with lentiviral supernatants in the presence of 8ug/ml polybrene, cells were cultured in fresh medium for several days. Subsequently, GFP+ cells were sorted by FACS and RNA was prepared.
