Description
CD3-positive T cells were negatively isolated from 10 SLE patients and 9 healthy controls without SLE. All of the SLE samples and control samples were compared with one another to identify baseline differences in expression due to the disease. Next, T cell preparations from 4 of the control subjects were stimulated with either Nitric Oxide (NOC-18) 600 uM for 24hr or stimulated through CD3/CD28 for 24hr to determine which genes were responsive to these signaling mechanisms. Here, we show that activity of the mammalian target of rapamycin (mTOR), which is a sensor of the mitochondrial transmembrane potential, is increased in SLE T cells. Activation of mTOR was inducible by NO, a key trigger of MHP which in turn enhanced the expression of HRES-1/Rab4, a small GTPase that regulates recycling of surface receptors through early endosomes. Expression of HRES-1/Rab4 was increased in SLE T cells and, in accordance with its dominant impact on the endocytic recycling of CD4, it was inversely correlated with diminished CD4 expression. HRES-1/Rab4 over-expression was also inversely correlated with diminished TCR protein levels. Combined with follow up studies, these results suggest that activation of mTOR causes the loss of TCR in lupus T cells through HRES-1/Rab4-dependent lysosomal degradation.

Description
Lamina propria and muscularis macrophages, were sorted at steady steate and 2h after oral exposure to an attenuated form of Salmonella, comparison among these populations showed that the muscularis macrophages quckly respond to the presence of intestinal bacteria, upregulating some important tissue protective genes. Overall design: intestinal macrophages from 3 mice were pooled into one RNA sample, the experiment was done control X infected and was repeated twice

Description
We used morpholinos and gene editing tools to inactivate the srsf5a gene. In contrast to srsf5a homozygous mutants that did not display any phenotypic traits, microinjection of sMOsrsf5a led to developmental defects. By using RNA sequencing on morphants and control embryos we were able to identify a plethora of morpholino inadvertant target. Overall design: Two biological replicates were used per conditions. Samples named CtrlMO consist in embryos injected with the control morpholino (5''-CCTCTTACCTCAGTTACAATTTATA-3'', Gene Tools). Samples named sMOsrsf5a consist in embryos injected with the morpholino against srsf5a (5''-GGATTCAGTCTCACCTCTCACTGCA-3'', Gene Tools).

- Affymetrix Rat Gene 1.0 ST Array (ragene10st)
Description
Neuronal differentiation of PC12 cells in response to NGF is a prototypical model in which signal duration determines a biological response. Sustained ERK activity induced by NGF, as compared to transient activity induced by EGF, is critical to the differentiation of these cells. To characterize the transcriptional program activated preferentially by NGF, we compared global gene expression profiles between cells treated with NGF and EGF for 2-4 hrs, when sustained ERK signaling in response to NGF is most distinct from the transient signal elicited by EGF. This analysis identified 69 genes that were preferentially upregulated in response to NGF.
Publication Title
Global expression analysis identified a preferentially nerve growth factor-induced transcriptional program regulated by sustained mitogen-activated protein kinase/extracellular signal-regulated kinase (ERK) and AP-1 protein activation during PC12 cell differentiation.
