Project description:Obesity is linked to increased mortality from many cancer types, and oesophageal adenocarcinoma displays one of the strongest epidemiological associations. The aim of this study was to dissect molecular pathways linking obesity with oesophageal adenocarcinoma and to determine if obesity is linked to increased aggressiveness of this disease. Affymetrix microarrays were used to identify altered signaling pathways in an oesophageal adenocarcinoma cell line following co-culture with isolated adipocytes from viscerally obese oesophageal adenocarcinoma patients (n=6).
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.

The aim of this study was to dissect molecular pathways linking obesity with oesophageal adenocarcinoma and to determine if obesity is linked to increased aggressiveness of this disease. Affymetrix microarrays were used to identify altered signaling pathways in an oesophageal adenocarcinoma cell line following co-culture with visceral adipose tissue from viscerally obese oesophageal adenocarcinoma patients (n=6).
Project description:Three oesophageal tissue derived cell lines, one from a normal tissue (HET1A) and two from tumour tissues (OE33 and OE199) were mixed with same number of each cell type in the same tube to get a mixed population. The C1 platform (Fluidigm) was used to capture single-cells and scATAC-seq protocols from Fluidigm ScriptHub is then used to generate the sequencing library. A single-cell ATAC-seq Bioinformatics pipeline is then developed to deconvolute the cells into their respective cell types.
Project description:White adipose tissue (WAT) is a central factor in the development of type 2 diabetes. Despite the epidemiological importance of WAT there is a paucity of translational models to study long term changes in mature adipocytes. Here, we describe a novel method for the culture of mature white adipocytes under a permeable membrane. Compared to existing culture methods such as adipose tissue explants and adipocyte ceiling culture, Membrane mature Adipocyte Aggregate Cultures (MAAC) are superior at maintaining adipogenic gene expression through 2 weeks of culture, do not dedifferentiate, and are under reduced hypoxic stress relative to adipose tissue explants. Unbiased RNA-Sequencing analysis indicates that the gene expression profile of MAAC in culture for 1 or 2 weeks is more similar to starting patient material than cultured adipose tissue explants, floating adipocytes, or in vitro-differentiated precursors from the same donor, with the fewest number of differentially expressed genes and the smallest fold-change in gene expression. Importantly, adipocytes from lean and obese patients can be cultured as MAAC, as can subcutaneous and visceral adipocytes, while maintaining depot-specific gene expression signatures. MAAC remain fully functional after long term culture, with similar responses to insulin and lipolytic stimuli compared to recently isolated cells. In addition, MAAC maintain the ability to crosstalk with other cell types, producing synergistic increases in IL6 and IL8 when co-cultured with macrophages, and respond robustly and predictably to diverse pharmacological agonism. Together, these abilities make MAAC a powerful tool for studying phenotypic changes in mature adipocytes, crosstalk between adipocytes and other cell types, and provide an improved translational model for drug development for the modulation of adipose tissue function.
