Description
A major goal in prostate stem cell biology is to identify genes, pathways, or networks that control self-renewal and multilineage differentiation. We hypothesize that 1,25 dihydroxyvitamin D3 can induce differentiation of prostatic progenitor/stem cells, thus serving as an in vitro model with which to study the molecular mechanisms of stem cell differentiation by 1,25 dihydroxyvitamin D3. 1,25 dihydroxyvitamin D3 elicits its effects primarily through transcriptional regulation of genes, so microarray studies were used to gain insight into the cellular response to 1,25 dihydroxyvitamin D3.

Description
Analysis of interferon-stimulated genes (ISGs) in various primary cells and immortalized cell lines, following type 1 interferon (IFN) treatment. Some cell types become resistant to HIV-1 infection following type 1 interferon treatment (such as macrophages, THP-1, PMA-THP-1, U87-MG cells and to a lesser extent, primary CD4+ T cells) while others either become only partially resistant (e.g., HT1080, PMA-U937) or remain permissive (e.g., CEM, CEM-SS, Jurkat T cell lines and U937); for more information see (Goujon and Malim, Journal of Virology 2010) and (Goujon and Schaller et al., Retrovirology 2013). We hypothesized that the anti-HIV-1 ISGs are differentially induced and expressed in restrictive cells compared to permissive cells and performed a whole genome analysis following type 1 IFN treatment in cell types exhibiting different HIV-1 resistance phenotypes.

Description
Epithelial-mesenchymal transition (EMT) has been linked to cancer progression and metastatic propensity. The 4T1 tumor is a clinically relevant model of spontaneous breast cancer metastasis. Here we characterize 4T1-derived cell lines for EMT, in vitro invasiveness and in vivo metastatic ability. Contrary to expectations, the 67NR cells, which form primary tumors but fail to metastasize, express vimentin and N-cadherin, but not E-cadherin. 4T1 cells, however, express E-cadherin, are highly migratory and invasive, and metastasize to multiple sites. The 66cl4 metastatic cells display mixed epithelial and mesenchymal markers, but are less migratory and invasive than 67NR cells. These findings demonstrate that the metastatic ability of breast cancer cells does not correlate with genotypic and phenotypic properties of EMT per se, and suggest that other processes may govern metastatic capability. Gene expression analysis also has not identified differences in EMT markers, but has identified several candidate genes that may influence metastatic ability.

Epithelial-mesenchymal transition (EMT) is not sufficient for spontaneous murine breast cancer metastasis.

Description
We performed a 3' RACE of a novel HIV RNA TAR-gag in order to determine the sequence of the RNA at the 3' end. Our data had shown that TAR-gag was potentially a noncoding RNA and our hypothesis was that TAR-gag ended somewhere prior to the end of the gag region of the HIV genome. The 3' RACE experiment showed that TAR-gag actually consists of four different RNA clusters, the longest of which ends at 615 bases from the transcription start site; this is in the middle of the p17 region of the gag gene. In addition, we sequenced all host RNAs in the EVs. Overall design: RNA from J1.1 and U1 exosomes was isolated and converted to cDNA. Sequencing libraries of the cDNA were made and a 3' RACE was perforemed to determine how long TAR-gag RNA is. Please note that the clustering analysis (published in PMID 28536264) was done only on the unfragmented samples (i.e. *-U samples).

Description
Translation initiation factor eIF4E is overexpressed early in breast cancers in association with disease progression and reduced survival. Much remains to be understood regarding the role of eIF4E in human cancer. Using immortalized human breast epithelial cells, we report that elevated expression of elF4E translationally activates the TGF pathway, promoting cell invasion, loss of cell polarity, increased cell survival and other hallmarks of early neoplasia. Overexpression of eIF4E is shown to facilitate selective translation of integrin 1 mRNA, which drives the translationally controlled assembly of a TGF receptor signaling complex containing 31 integrins, -catenin, TGF receptor I, E-cadherin and phosphorylated Smads2/3. This receptor complex acutely sensitizes non-malignant breast epithelial cells to activation by typically sub-stimulatory levels of activated TGF. TGF can promote cellular differentiation or invasion and transformation. As a translational coactivator of TGF, eIF4E confers selective mRNA translation, reprogramming non-malignant cells to an invasive phenotype by reducing the set-point for stimulation by activated TGF. Overexpression of eIF4E may be a pro-invasive facilitator of TGF activity.

Description
Septic shock is the most severe complication of sepsis, associated with high mortality. The patient's response to supportive therapy is very heterogeneous and the underlying mechanisms are still elusive. In order to identify which are the actors (genes and pathways) that play a role in establishing the response, we investigate the whole blood transcriptome in septic shock patients with positive and negative responses to early supportive hemodynamic therapy, assessed by changes in SOFA scores within the first 48 hours from ICU admission. We pinpointed genes and pathways that are differently modulated and enriched respectively within 48hrs between responders and non-responders. Overall design: We analyzed 31 patients (17 Responders and 14 Not Responders to early therapy). For each patient, 2 samples were collected. In particular the first sample (T1) collected within 16 hours from ICU admission whereas the second (T2) collected within 48 hours from ICU admission. Experimental groups (Responders and Not Responders) are defined accordingly with SOFA scores improvements within 48 hours.
