Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
Given their precipitous encounter with the environment, newborn infants might be expected to possess abundant immunoprotective mechanisms. Paradoxically, their T cells display grossly impaired Th1 anti-bacterial and anti-viral responses. This study identifies factors produced by neonatal CD4 T cells when compared with adult naive CD4 T cells and highlights CXCL8 as a pivotal effector molecule in neonatal T cells. Using Affimetrix microarray we compared gene expression in cord blood derived CD4 T cells with naive CD4 T cells from adults after polyclonal stimulation.

Description
To elucidate the mechanisms by which the mir-200 and the miR-183~96~182 cluster could regulate EMT and thus cellular migration, invasion and metastasis in NSCLC, we searched for common predicted targets of these microRNA families that might have a potential role in these biological processes. First we performed a cross comparison of multiple gene expression datasets from our mouse models of metastasis. We overlapped 224 genes that were elevated greater than four-folds upon Zeb1 induction in 393P cells with 210 genes that showed greater than two-fold increase in expression in the metastatic 344SQ cells compared to the non-metastatic 393P cells and 143 genes that were repressed to less than 0.5-fold in cells with exogenous expression of miR-200. This resulted in an enriched list of 45 genes that are potential miR-200 targets having a role in the process of EMT and metastasis. Next we performed an overlap of genes that were predicted targets of the miR-200 family members and the miR-183~96~182 cluster using the microRNA prediction algorithms miRanda (www.microRNA.org) and identified a list of 17 highly conserved common targets with a mirSVR score less than -6.0. The only 2 genes common in both the overlapping subsets were Zeb1 and Foxf2.

Description
An unanticipated feature of the human neonatal CD4 T cell response is a robust capacity to produce CXCL8. However, this ''innate-like'' function dissipates with age and is scarce in the adult. Here, we investigated the fate of CD4+CXCL8+ cells and their transition into conventional adaptive T cells. We show that CXCL8 is imprinted on immature thymocytes prior to TCR signalling and is maintained in T cell committed thymic progenitors and recent thymic emigrants (RTEs) of adults as well as neonates. Hence, rather than being unique to neonates, CXCL8-producing CD4+ T cells decrease with age in humans (and in humanised mice) owing to the decline in thymic output, coupled with the cells' peripheral expansion. By cloning of CXCL8+CD4+ cells from cord blood, we were able to track effector function within daughter cells and demonstrate that these cells can convert to IFN-g producing cells. In sum, we provide direct evidence that 'innate like' CXCL8-producing CD4+ T cells emerge from the thymus and can transition into conventional adaptive Th1 cells Overall design: Examination of RNA-Seq count data from 96 single cells

Description
The biologic basis for NSCLC metastasis is not well understood. Here we addressed this deficiency by transcriptionally profiling tumors from a genetic mouse model of human lung adenocarcinoma that develops metastatic disease owing to the expression of K-rasG12D and p53R172H. As a tool to investigate the biologic basis for metastasis in this model and to query the roles of specific genes in this signature, we isolated adenocarcinoma cell lines from these mice and used them to develop a syngeneic tumor model in wild-type littermates. Transcriptional profiling of the highly metastatic subcutaneous tumors revealed genes that regulate, among other processes, epithelial-to-mesenchymal transition and intra-tumoral inflammation and angiogenesis, whereas the non-metastatic tumors did not.

Description
Metastatic disease is a primary cause of cancer-related death, and factors governing tumor cell metastasis have not been fully elucidated. Here we addressed this question by using tumor cell lines derived from mice that develop metastatic lung adenocarcinoma owing to expression of mutant K-ras and p53. A feature of metastasis-prone tumor cells that distinguished them from metastasis-incompetent tumor cells was plasticity in response to changes in their microenvironment. They transited reversibly between epithelial and mesenchymal states, forming highly polarized epithelial spheres in 3-dimensional culture that underwent epithelial-mesenchymal transition (EMT) following treatment with transforming growth factor-beta or injection into syngeneic mice. This plasticity was entirely dependent upon the microRNA-200 family, which decreased during EMT. Forced expression of miR-200 abrogated the capacity of these tumor cells to undergo EMT, invade, and metastasize and conferred transcriptional features of metastasis-incompetent tumor cells. We conclude that microenvironmental cues direct tumor metastasis by regulating miR-200 expression.

Description
Context: Polycystic ovarian syndrome (PCOS), the most common endocrine disorder of reproductive- aged women, is associated with systemic low-grade inflammation. Objective: We propose that increased or altered intrafollicular inflammatory reactions also occur in periovulatory follicles of PCOS patients. Design: Gene profiling and quantitative PCR (qPCR) analyses in granulosa-lutein cells (GCs) collected from PCOS and non-PCOS women undergoing in vitro fertilization were compared with serum and follicular fluid (FF) levels of cytokines and chemokines. Setting: This was a university-based study. Patients: Twenty-one PCOS and 45 control patients were recruited: demographic, hormone, body mass index, and pregnancy outcomes were abstracted from patient data files. Interventions:GCcytokine/chemokinemRNAswere identified and analyzed by gene-chip microarrays/ qPCR before and after culture withhumanchorionic gonadotropin, DHT, IL-6, or IL-8; serum/FF cytokine levels were also analyzed. Main Outcome Measures: Relative serum/FF cytokine levels and GC cytokine expression before and after culture were compared and related to body mass index. Results: The following results were found: 1) PCOS GCs express elevated transcripts encoding cytokines, chemokines, and immune cell markers, 2) based on gene profiling and qPCR analyses, obese PCOS patients define a distinct PCOS disease subtype with the most dramatic increases in proinflammatory and immune-related factors, and 3) human chorionic gonadotropin and DHT increased cytokine production in cultured GCs, whereas cytokines augmented cytokine and vascular genes, indicating that hyperandrogenism/elevated LH and obesity in PCOS women augment intrafollicular cytokine production. Conclusions: Intrafollicular androgens and cytokines likely comprise a local regulatory loop that impacts GC expression of cytokines and chemokines and the presence of immune cells; this loop is further enhanced in the obese PCOS subtype.
