Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
Vitamin D deficiency has been associated with increased esophageal cancer risk. Vitamin D controls many downstream regulators of cellular processes including proliferation, apoptosis, and differentiation. We evaluated the effects of vitamin D supplementation on global gene expression in patients with Barrett's esophagus.

Description
Background: The diverse immunomodulatory effects of vitamin D are increasingly being recognized. However, the ability of oral vitamin D to modulate immune responses in vivo has not been established in humans. Methods: Twenty healthy adults were randomized to receive placebo or a single high dose of vitamin D3 (cholecalciferol) one hour after localized skin irradiation with an erythemogenic dose of ultraviolet radiation. Primary outcomes included skin redness, skin thickness, and tissue expression of inflammatory mediators (TNF- and iNOS). Secondary outcomes included microarray analyses. Results: As compared to placebo, subjects receiving vitamin D3 (200,000 IU) demonstrated reduced expression of TNF- (p=0.04) and iNOS (p=0.02) in skin biopsies 48 hours after ultraviolet light exposure. Demonstrated trends included reduced skin redness (p=0.17), and reduced skin thickness (p=0.09) in subjects receiving vitamin D3 (200,000 IU). Unsupervised clustering of individuals based on global gene expression revealed that subjects with enhanced skin barrier repair expression profiles had higher serum vitamin D3 levels (p=0.007), increased arginase expression (p=0.005), and a sustained reduction in skin redness (p=0.02) after treatment, as compared to subjects with enhanced inflammatory gene expression profiles.

Description
Age-related alterations in immunity have been linked to increased incidence of infections and decreased responses to vaccines in the aging population. Human peripheral blood monocytes are known to promote antigen presentation and antiviral activities; however, the impact of aging on monocyte functions remains an open question. We present an in-depth global analysis examining the impact of aging on classical (CD14+CD16-), intermediate (CD14+CD16+), and non-classical (CD14dimCD16+) monocytes. Monocytes sorted from non-frail healthy adults (18-40 yrs) and OLD ( 65 yrs) individuals were analyzed after stimulation with TLR4, TLR7/8, and RIG-I agonists. Our data showed under non-stimulated conditions, monocyte subsets did not reveal significant age-related alternations; however, agonist stimulated-monocytes from adults and OLD subjects did show differences at the transcriptional and functional levels. These alternations in many immune-related transcripts and biological processes resulted in reduced production of IFN, IFN, IL-1, CCL20, and CCL8, and higher expression of CX3CR1 in monocytes from OLD subjects. Our findings represent a comprehensive analysis of the influence of human aging on pattern recognition receptors signaling and monocyte functions, and have implications for strategies to enhance the immune response in the context of infection and immunization.
