Bi-directional interactions of omental adipocytes and SKOV3ip1 cells

ABSTRACT: Primary human omental adipocytes were isolated from patients with non-cancer conditions. Subsequently, gene expression profiled in adipocytes and ovarian cancer cell line (SKOV3ip1) alone (control) or under co-culture conditions. Following co-culture cells were separated and total RNA isolated for microarray analysis.

A study of changes in lipid metabolism of ovarian cancer cells co-cultured with adipocytes: UPLC-QTRAP MS analysis

Project description:The study investigated the interaction between omental adipocytes and OvCa cells, as a follow up to preliminary data indicating this leads to reprograming of metabolic (especially lipid) profiles in both adipocytes and OvCa cells as ovarian cancer cells (OvCa) readily metastasize to the omental fat pad in the abdomen and stimulate the release of fatty acids. In order to mimic the interaction between OvCa and omental adipocytes during metastasis, a coculture system was used that employed OvCa cells and primary human adipocytes isolated from omentum. Human primary adipocytes were isolated from omental explants from patients undergoing surgery for benign conditions. After surgical removal, omental tissue was digested with collagenase I, and primary cultures of adipocytes were established, characterized, and incorporated into the co-culture. The primary adipocytes were isolated and co-cultured with the OvCa cell line Skov3ip1. In this current submission, the the samples will be collected at 4, 18 and 24 hour time points post co-culture to determine the time dependent effect on lipid mediators, including oxylipins and ceramides. The study results included in this DRCC submission were the 18 hour time point data for oxylipins and ceramides from targeted metabolomic analysis of lipid mediators performed by the Newman lab.

Gene expression analysis of omental and mesenteric adipose tissue in Crohn's disease and ulcerative colitis

Project description:Our hypothesis is that in IBD patients intestinal bacteria translocation into the intra-abdominal fat depots affects adipocyte morphology and gene expression. The study aimed to study adipocyte gene expression of omental (OM) and mesenteric (MES) adipose tissue of ulcerative colitis (UC) and crohn's disease (CD). Total RNA was extracted from isolated adipocytes from omental and mesenteric adipose tissue of CD and UC patients. Microarray experiments were performed in duplicates of 4 different pools of RNAs extracted from adipocytes isolated from OM and MES of UC patients (n=5) and CD patients (n=5) respectively.

Effects of rosiglitazone on human omental adipose tissue gene expression

Project description:The cellular mechanisms by which PPARγ improves metabolism in mature human adipocytes and potential depot differences in its actions are poorly understood. To assess the global effects of PPARγ activation on human omental gene expression, we conducted microarray analysis of control vs. rosiglitazone-treated omental tissues from human subjects.

Gene expression analysis of subcutaneous and omental adipose tissue from obese, insulin-resistant women

Project description:The association between central obesity and insulin resistance reflects the properties of visceral adipose tissue. Our aim was to gain further insight into this association by analysing the lipid composition of subcutaneous and omental adipose tissue in obese women with and without insulin resistance. Subcutaneous and omental adipose tissue and serum were obtained from 29 obese nondiabetic women, 13 of whom were hyperinsulinemic. Histology, and lipid and gene profiling were performed. In omental adipose tissue of obese, insulin-resistant women, adipocyte hypertrophy and macrophage infiltration were accompanied by an increase in GM3 ganglioside and its synthesis enzyme ST3GAL5; in addition, phosphatidylethanolamine (PE) lipids were increased and their degradation enzyme, PEMT, decreased. ST3GAL5 was expressed predominantly in adipose stromovascular cells and PEMT in adipocytes. Insulin resistance was also associated with an increase in PE lipids in serum. Total RNA was isolated and up to 400 ng of total RNA per sample was labelled and hybridized to Illumina HumanHT-12_V4 expression BeadChip platform. Paired subcutaneous and omental samples from 6 women were analysed.

Omental preadipocytes stimulate matrix remodeling and IGF signaling to support ovarian cancer metastasis

Project description:Ovarian cancer can metastasize to the omentum, which is associated with a complex tumor microenvironment. Omental stromal cells facilitate ovarian cancer colonization by secreting cytokines and growth factors. Improved understanding of the tumor supportive functions of specific cell populations in the omentum could identify strategies to prevent and treat ovarian cancer metastasis. Here, we showed that omental preadipocytes enhance the tumor initiation capacity of ovarian cancer cells. Secreted factors from preadipocytes supported cancer cell viability during nutrient and isolation stress and enabled prolonged proliferation. Co-culturing with pre-adipocytes led to upregulation of genes involved in extracellular matrix (ECM) organization, cellular response to stress, and regulation of insulin-like growth factor (IGF) signaling in ovarian cancer cells. IGF-1 induced ECM genes and increased alternative NF-κB signaling by activating RelB. Inhibiting the IGF-1 receptor (IGF1R) initially increased tumor omental adhesion but decreased growth of established preadipocyte-induced subcutaneous tumors as well as established intraperitoneal tumors. Together, this study shows that omental preadipocytes support ovarian cancer progression, which has implications for targeting metastasis.

Identification of the novel function of adipocyte plasma membrane associated protein (APMAP) in gestational diabetes mellitus by proteomic analysis of omental adipose tissues

Project description:Gestational diabetes mellitus (GDM) is considered as the early stage of type 2 diabetes mellitus. In this study, we compared the demographic and clinical data between six GDM and six NGT (healthy controls) and found the HOMA-IR was increased in GDM. Previously, many researches had proved that omental adipose tissues dysfunction could induce insulin resistance. Thus, in order to investigate the cause of the insulin resistance in GDM, label-free proteomics was used to discover differentially expressed proteins in omental adipose tissues between GDM and NGT. A total of 3529 proteins identified, including 66 significantly changed proteins. Adipocyte plasma membrane associated protein (APMAP also called C20orf3) was one of changed proteins and down regulated in GDM omental adipose tissues. Further, mature 3T3-L1 adipocytes were used to simulate omental adipocytes and we found that inhibited the expression of APMAP by RNAi would impaired the insulin signaling and activated the NFkB signaling in adipocytes. These results indicated that the decreased of APMAP in mental adipose tissues may be important in process of the insulin resistance in GDM.
