Microarray Analysis of Genes Regulated by Macrophage-Conditioned Media Treatment of Human Pre-Adipocytes

ABSTRACT: A major development in the study of obesity is the recognition that the condition is characterised by chronic mild inflammation. Within adipose tissue, this involves the infiltration of macrophages, as well as the direct inflammatory response of the adipocytes and pre-adipocytes. This study has used Agilent whole-genome microarrays to examine the effects of macrophage-conditioned medium on the global inflammatory response of human pre-adipocytes.

Microarray Analysis of Genes Regulated by Macrophage-Conditioned Media Treatment of Human Pre-Adipocytes

Project description:A major development in the study of obesity is the recognition that the condition is characterised by chronic mild inflammation. Within adipose tissue, this involves the infiltration of macrophages, as well as the direct inflammatory response of the adipocytes and pre-adipocytes. This study has used Agilent whole-genome microarrays to examine the effects of macrophage-conditioned medium on the global inflammatory response of human pre-adipocytes. Human pre-adipocytes (SGBS cells) were treated with macrophage (U937 cells) conditioned medium for 24 h. Control pre-adipocytes were treated with unconditioned medium (control) or RPMI-1640 media alone to control for differences in media used to culture the U937 cells. There were 5 biological replicates per group.

Microarray Analysis of Genes Regulated by Macrophage-Conditioned Media Treatment of Human Adipocytes

Project description:A major development in obesity research is the recognition that the condition is characterized by chronic mild inflammation. Within adipose tissue, this involves the infiltration of macrophages as well as a direct inflammatory response of adipocytes. This study has used Agilent whole-genome microarrays to examine the effects of macrophage-conditioned medium on the global inflammatory response of human adipocytes. Human adipocytes (SGBS cells), differentiated in culture, were treated with macrophage (U937 cells) conditioned media for 4 or 24 h. Control SGBS cells were treated with unconditioned media (control) or RPMI media alone to control for differences in media used to culture U937 cells. There were 6 replicates per group.

Expression data on 3T3-L1 adipocytes treated with leukemia cell-conditioned media

Project description:We used Affymetrix microarray to survey the global gene expression changes in adipocytes that have been treated with acute lymphoblastic leukemia cell conditioned media.

Expression data from differentiated 3T3-L1 pre-adipocytes.

Project description:Stearoyl-CoA desaturase (SCD) is the rate-limiting enzyme catalyzing the conversion of saturated fatty acids palmitate and stearate to monounsaturated fatty acids palmitoleate and oleate. During adipocyte differentiation, SCD expression increases concomitantly with several transcription factors and lipogenic genes. We used microarrays to examine gene expression in differentiated pre-adipocytes treated with and without an SCD inhibitor. On day 7 of adipocyte differentiation, total RNA was extracted from adipocytes. Two conditions were selected for comparison: total RNA extracted from adipocytes treated with DMSO (control) and or a SCD inhibitor.

Expression data from human SGBS adipocytes under hypoxic conditions

Project description:Hypoxia in adipose tissue is suggested to be involved in the development of a chronic mild inflammation, which in obesity can further lead to insulin-resistance. The effect of hypoxia on gene expression in adipocytes seems to play a central role in this inflammatory response observed in obesity. However, the global impact of hypoxia on transcriptional changes in human adipocytes is unclear. Therefore, we compared gene expression profiles of human Simpson-Golabi-Behmel syndrome (SGBS) adipocytes under normoxic or hypoxic conditions to detect hypoxia-responsive genes in adipocytes by using whole human genome microarrays. Human SGBS adipocytes were cultured in a hypoxic environment (1% O2) for 3, 6 and 16 hours and the control group was cultured under normoxic conditions (21% O2). Total RNA was prepared from control and treated SGBS cells, in triplicate experiments, and probes were hybridized on ‘Human Genome U133 2.0’ arrays (Affymetrix).

Hypoxia-induced modulation of gene expression in human adipocytes - A microarray study

Project description:Obesity is characterised by expansion of white adipose tissue, accompanied by an inflamatory response. It has been proposed that the inflammatory state observed may be linked to relative hypoxia in clusters of adipocytes distant from vasculature. Adipose tissue hypoxia has been observed in both animal models and human studies in obesity, and has been linked to insulin resistance. This study has used Agilent whole-genome microarrays to examine the effects of acute hypoxia on the global gene expression in human adipocytes. Human adipocytes (Zen-bio cells) were incubated in hypoxic conditions (1% O2) for 24 h. Control human adipocytes were incubated under normoxic conditions (21% O2). Eight biological replicates were prepared for each experimental condition, and RNA was pooled from two biological replicates, giving a total of n=4 array replicates.
