Description
Tanning is a skin protection mechanism against UV radiation. Pigment production initiates hours after exposure, and the mechanism controlling this delay was unknown. Here we reveal a skin UV-protection timer, governed by damped oscillatory dynamics of the melanocyte master regulator, MITF, which after UV exposure, synchronizes regulatory programs, first cell survival and later pigmentation. Remarkably, the same amount of UV dosage resulted in higher pigmentation of human skin when given every-other day compared to daily exposure. Daily UV exposure appears to perturb MITF dynamics, thus re-ordering the survival and pigmentation programs. This demonstrates that the skin is more sensitive to frequency than quantity of UV exposure. Mathematical modeling identified a double negative regulatory loop involving HIF1a and microRNA-148a that regulates MITF dynamics. Our study suggests evolutionary leverage of the UV-protection timer, as it evolved to induce maximum protection with minimum damage for the reduction of skin cancer risk.

- Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
The transcription factor network in Hodgkin lymphoma (HL) represents a unique composition of proteins found in no other hematopoietic cell. Among these factors, an aberrant expression of the T cell transcription factor GATA-3 is observed in the B cell-derived Hodgkin and Reed/Sternberg (HRS) tumor cells. Herein, we elucidated the regulation and function of this factor in HL

Description
Purpose: To determine effects of arsenic on gene expression in polarized primary human bronchial epithelial (HBE) cells and impact on transcriptional response to Pseudomonas aeruginosa infection Methods: mRNA profiles of HBE cells from 6 donors exposed to 0, 5, 10 or 50 ug/L total arsenic +/- Pseudomonas aeruginosa (48 samples) were generated using Illumina sequencing, aligned in CLC Genomics workbench and analyzed for DE in EdgeR Findings: 20-30 million reads were mapped per sample and transcripts were identifed that were significantly differentially expressed in response to arsenic and Pseudomonas aeruginosa Overall design: Gene expression profiles of HBE cells from 6 donors exposed to three concentrations of arsenic +/- Pseudomonas were generated using mRNA sequencing
Publication Title
Arsenic alters transcriptional responses to Pseudomonas aeruginosa infection and decreases antimicrobial defense of human airway epithelial cells.
