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.

Project description:Obesity is characterized by a chronic auto-inflammation of the hypertrophied white adipose tissue (WAT) associated with metabolic and vascular complications. WAT of obese subjects produces inflammatory factors like cytokines (IL6, TNF-alpha) and chemokines (CCL2 and IL-8) originating mainly from the accumulated macrophages. WAT macrophages profoundly affect adipose cell biology leading in particular to the inflammation of the adipocytes and altered differentiation of their precursors, the pre-adipocytes. We previously showed that conditioned media from WAT macrophages (ATM CM) induced inflammation in human pre-adipocytes. We performed pangenomic cDNA microarrays analysis to compare gene expression profiles between control and ATM CM treated preadipocytes. By a functional analysis, we identified the biological themes that best characterized the proinflammatory preadipocytes. The most significantly overrepresented GO Cellular Component categories were "cytokine-cytokine receptor interaction" and "chemokine signaling pathway", emphasizing the importance of cytokine and chemokine production by the inflammatory preadipocyte. The chemokines acting in concert to recruit leukocytes in inflamed tissues, still need to be more precisely identified in human WAT. Thus, our data lead to the identification of new chemokines involved in attraction of immune cells in inflamed human WAT. The transcriptomic profile of human preadipocytes was compared to that of preadipocyes treated by macrophages isolated from human adipose tissue. Two-condition experiment,human control preadipocyte vs preadipocyte treated by macrophages from adipose tissue. 5 biological replicates (with a dye-swap design).

Project description:Omental adipose tissue explants were cultured for 24h in serum-free medium in the presence of vehicle (control medium) or macrophage (LPS) and T-cell (anti-CD3/28) stimulants (active medium). SGBS human preadipocytes were differentiated into adipocytes and then exposed to 25% v/v control or active medium.

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.

Project description:The disturbance of adipose tissue in obesity highly correlates with cancer progression. To investigate the impacts of obesity on triple-negative breast cancer (TNBC), we performed an in vitro system culturing TNBC cells with human white adipocytes-conditioned medium (hAd-CM). The gene expression profiling between each condition was then assessed by RNA-seq.

Project description:Analysis of gene expression levels of HER2-positive breast cancer cells exposed to the conditioned medium from adipocytes. The hypothesis tested in the present study was that adipocytes secrete factors that induce the resistance of cancer cells to antibody-dependent cellular cytotoxicity mediated by trastuzumab. The results provide insight into the genes that may be involved in the adipocyte-induced cancer resistance to trastuzumab treatment. BT474 cells or SKBR3 cells were exposed to the conditioned medium (CM) from differentiated hMADS (#hMADS) or to the control medium for 2 h. Total RNA was extracted and analyzed. The experiment was performed in triplicate.
