Effects of exercise on miRNA expression level in human NK Cells

ABSTRACT: Exercise leads to a rapid change in the profile of gene expression in NK cells. We hypothesized that microRNA expression in circulating NK cells would also be affected by brief exercise.

Effects of exercise on miRNA expression level in human NK Cells

Project description:Exercise leads to a rapid change in the profile of gene expression in NK cells. We hypothesized that microRNA expression in circulating NK cells would also be affected by brief exercise. Eleven healthy men (20-29 yr old) performed 10 2-min bouts of cycle ergometer exercise interspersed with 1-min rest at a constant work equivalent to about 77% of VO2max. A baseline blood sample was taken before the and immediately after the exercise. NK cells were isolated from PBMC using a negative magnetic cell separation methods (Miltenyi Biotec Kit #130-092-657 and the autoMACSM-BM-. Pro Separator). Total RNA was extracted using TRIzolM-BM-.. For this study we used Agilent Human miRNA microarrays V2 (total of 22 chips).

Effects of exercise on gene expression level in human NK Cells

Project description:We tested the hypothesis on the mechanisms responsible for the early control of NK cell function by identifying a discrete set of genes in circulating NK cells that were altered by exercise. Exercise leads to a rapid change in the profile of gene expression in NK cells. Twelve healthy men (20-29 yr old) performed 10 2-min bouts of cycle ergometer exercise interspersed with 1-min rest at a constant work equivalent to about 77% of VO2max. A baseline blood sample was taken before the and immediately after the exercise. NK cells were isolated from PBMC using a negative magnetic cell separation methods (Miltenyi Biotec Kit #130-092-657 and the autoMACSM-BM-. Pro Separator). Total RNA was extracted using TRIzolM-BM-.. For this study we used Affymetrix plus 2 (total of 24 chips).

Effects of exercise on microRNA expression level in human monocytes

Project description:Exercise leads to a rapid change in the profile of gene expression in monocytes. We hypothesized that microRNA expression in circulating monocytes would also be affected by brief exercise. Twelve healthy men (22-30yr old) performed 10 2-min bouts of cycle ergometer exercise interspersed with 1-min rest at a constant work equivalent to about82% of VO2max. A baseline blood sample was taken before the and immediately after the exercise. Monocytes were isolated from PBMC using a negative magnetic cell separation methods (Miltenyi Biotec Monocyte Isolation Kit II, human #130-091-153 and the autoMACSM-BM-. Pro Separator). Total RNA was extracted using TRIzolM-BM-.. For this study we used Agilent Human miRNA microarrays V2 (total of 24 arrays).

Effects of exercise on miRNA expression level in human neutrophils

Project description:Exercise leads to a rapid change in the profile of gene expression in circulating neutrophils. We hypothesized that miRNA expression in circulating neutrophils would also be affected by brief exercise. Eleven healthy men (19-30 yr old) performed 10 2-min bouts of cycle ergometer exercise interspersed with 1-min rest at a constant work equivalent to about 76% of VO2max. A baseline blood sample was taken before the and immediately after the exercise. Neutrophils were isolated using OptiPrep Density Gradient Medium (SIGMA). Total RNA was extracted using TRIzolM-BM-.. For this study we used Agilent Human miRNA microarrays V2 (total of 22 chips).

Effects of exercise on miRNA expression in human peripheral blood mononuclear cells (PBMCs)

Project description:Exercise leads to a rapid change in the profile of gene expression in circulating PBMCs. We hypothesized that miRNA expression in circulating PBMCs would also be affected by brief exercise. 12 healthy men (19-30 yr old) performed 10 2-min bouts of cycle ergometer exercise interspersed with 1-min rest at a constant work equivalent to about 76% of VO2max. A baseline blood sample was taken before and immediately after the exercise. Neutrophils were isolated using OptiPrep Density Gradient Medium (SIGMA). Total RNA was extracted using TRIzol®. For this study we used Agilent Human miRNA microarrays V2 (total of 24 chips).

Voluntary exercise suppresses tumor growth through exercise-directed recruitment and intratumoral infiltration of NK cells

Project description:Voluntary exercise reduces the risk of cancer and lowers the risk of disease recurrence. Yet the mechanisms for this protection remain to be elucidated. Here we demonstrate that exercise halves tumor growth through an exercise-dependent mobilization and intratumoral infiltration of NK cells in malignant melanoma. Using voluntary wheel running, we show that exercise prior to and during B16 tumor challenge reduced tumor growth by 67%, and this reduction was associated with increased inflammation and immune cell infiltrates, especially NK cells, in the tumors from exercising mice. Depletion of NK cells blunted the exercise-dependent reduction in tumor growth. Moreover, during exercise, NK cells were engaged through an epinephrine-dependent mobilization to the circulation and redistributed to peripheral tissues through an IL-6 dependent mechanism. This study highlights the importance of exercise-dependent immune regulation in the control of malignant melanoma Gene expression profile of melanoma tumor tissue from two groups of exercise and non-exercise mice
