Description
NOD mice are an inbred strain that display enhanced MZ B cell differentiation from an early age. Interestingly, several lines of evidence implicate MZ B cells in this strain as important contributors to the T cell mediated beta cell destruction associated with the development of type 1 diabetes (T1D). In order to develop a better understanding of the underlying causes for augmented MZ B cell production in NOD mice, we obtained the transcriptional profiles of FO and MZ subsets and TR precursors from NOD mice and compared them to those of the B6 strain.

Description
Stem cell antigen-1 (Sca-1 or Ly6A) is a member of the Ly6 family of glycosyl phostidylinositol (GPI)-anchored cell surface proteins. To determine the potential mechanisms by which Sca-1 regulates cell migration, adhesion, and tumor development; we performed an Affymetrix mouse genome 430A 2.0 array on cDNA comparing shLuc and shSca-1 from cells grown in vitro.

Description
Serum response factor (SRF) is a transcription factor that binds to the serum response element (SRE) of genes that are expressed in response to mitogens. SRF plays essential roles in muscle and nervous system development; however, little is known about the role of SRF during liver growth and function. To examine the function of SRF in the liver, we generated mice in which the Srf gene was specifically disrupted in hepatocytes. The survival of mice lacking hepatic SRF activity was lower than that of control mice; moreover, surviving mutant mice were smaller and had lower blood glucose and triglyceride levels compared with control mice. Srf-deficient livers were also smaller than control livers, hepatocyte morphology was abnormal, and liver-cell proliferation and viability was compromised. Gene array and quantitative RT-PCR analysis of SRF depleted livers revealed a reduction in mRNAs encoding components of the growth hormone/IGF1 pathway, cyclins, several metabolic regulators, and cytochrome p450 enzymes. Conclusion: SRF is essential for hepatocyte proliferation and survival, liver function, and control of postnatal body growth by regulating hepatocyte gene expression.

Background and Aims: Although the zinc finger transcription factor GATA4 has been implicated in regulating jejunal gene expression, the contribution of GATA4 in controlling jejunal physiology has not been addressed. Methods: We generated mice in which the Gata4 gene was specifically deleted in the small intestinal epithelium. Measurements of plasma cholesterol and phospholipids, intestinal absorption of dietary fat and cholesterol, and gene expression were performed on these animals. Results: Mice lacking GATA4 in the intestine displayed a dramatic block in their ability to absorb cholesterol and dietary fat. Comparison of the global gene expression profiles of control jejunum, control ileum, and GATA4 null jejunum by gene array analysis demonstrated that GATA4 null jejunum lost expression of 53% of the jejunal-specific gene set and gained expression of 47% of the set of genes unique to the ileum. These alterations in gene expression included a decrease in mRNAs encoding lipid and cholesterol transporters as well as an increase in mRNAs encoding proteins involved in bile acid absorption. Conclusion: Our data demonstrate that GATA4 is essential for jejunal function including fat and cholesterol absorption and confirm that GATA4 plays a pivotal role in determining jejunal versus ileal identity.
