View SamplesCD133 is expressed by a subpopulation of human fetal hair follicle placode cells during early hair development. Its expression, which is gradually lost as the placode matures, correlates with early morphogenesis.
CD133 expression correlates with membrane beta-catenin and E-cadherin loss from human hair follicle placodes during morphogenesis.

View SamplesDermal fibroblasts (dFB) resist infection by locally differentiating into adipocytes and producing the antimicrobial peptide cathelicidin in response to S. aureus. We found that neonatal dFB were highly adipogenic whereas this adipogenic function was lost during adulthood. To better understand the molecular nature of the change in antimicrobial and adipogenic function of dFB, we profiled the transcriptomes of primary dFB isolated at different ages by RNA-seq. RNA-seq identified the pro-adipogenic to pro-fibrotic gene signature switch in dFB during aging, and identified TGF-beta as the top up-regulated pathway that was activated in 2M dFB compared to neonatal P1 dFB. Overall design: Examination of differentially expressed genes in cultured primary dermal fibroblasts/pre-adipocytes isolated from mouse skin with various ages.

View SamplesThe PI3K/Akt signaling pathway impacts various aspects of CD8 T cell homeostasis, such as effect versus memory cell differentiation, during viral infection. We used microarrays to determine which downstream molecules were affected and what other signaling pathways were interconnected with the Akt pathway by constitutive activation of Akt in LCMV-infected CD8 T cells.
Signal integration by Akt regulates CD8 T cell effector and memory differentiation.

View SamplesThe insulin-like growth factor-I (IGF-IR) and androgen (AR) receptors are important players in prostate cancer biology. Functional interactions between the IGF-I and androgen signaling pathways seem to have crucial roles in the progression of prostate cancer from early (benign) to advanced (metastatic) stages. DNA methylation is a major epigenetic alteration affecting gene expression. Hypermethylation of tumor suppressor promoters is a frequent event in human cancer, leading to inactivation and repression of specific genes. The aim of the present study was to identify the entire set of methylated genes (methylome) in a cellular model that replicates prostate cancer progression.
Global methylation analysis identifies PITX2 as an upstream regulator of the androgen receptor and IGF-I receptor genes in prostate cancer.
