Gastrointestinal Complications of Obesity

Obesity is usually associated with morbidity related to diabetes mellitus and cardiovascular diseases. However, there are many gastrointestinal and hepatic diseases for which obesity is the direct cause [e.g. non-alcoholic fatty liver diseases (NAFLD)] or is a significant risk factor, such as reflux esophagitis and gallstones. When obesity is a risk factor, it may interact with other mechanisms and result in earlier presentation or complicated diseases. There are increased odds ratios or relative risks of several gastrointestinal complications of obesity: gastroesophageal reflux disease (GERD), erosive esophagitis, Barrett ’s esophagus, esophageal adenocarcinoma, erosive gastritis, gastric cancer, diarrhea, colonic diverticular disease, polyps, cancer, liver disease including NAFLD, cirrhosis, hepatocellular carcinoma, gallstones, acute pancreatitis, and pancreatic cancer.

Shashkov, Nora M.A. Ponce, Carlos A. Stortz, Nikolay E. Nifantiev, Anatolii I. UsovAbstractFucosylated chondroitin sulfate (FCS) HeSp was isolated from the Patagonian sea cucumber Hemioedema spectabilis. Ion-exchange chromatography was applied for purification of the FCS from the crude extract of sulfated polysaccharides. Analysis of monosaccharide and sulfate content of HeSp revealed the molar ratio of GlcA:GalNAc:Fuc:SO3Na as 1.15:1:1.1:3.9. Molecular weight...

Cancer immune evasion is achieved through multiple layers of immune tolerance mechanisms including immune editing, recruitment of tolerogenic immune cells, and secretion of immunosuppressive cytokines. Recent success with immune checkpoint inhibitors in cancer immunotherapy suggests a dysfunctional immune synapse as a pivotal tolerogenic mechanism. Tumor cells express immune synapse proteins to suppress the immune system, which is often modulated by epigenetic mechanisms. When the methylation status of key immune synapse genes was interrogated, we observed disproportionately hypermethylated costimulatory genes and hypometh...

Increased rates of locoregional recurrence are observed in patients with basal-like breast cancer (BC) despite the use of radiation therapy (RT); therefore, approaches that result in radiosensitization of basal-like BC are critically needed. Using patients’ tumor gene expression data from 4 independent data sets, we correlated gene expression with recurrence to find genes significantly correlated with early recurrence after RT. The highest-ranked gene, TTK, was most highly expressed in basal-like BC across multiple data sets. Inhibition of TTK by both genetic and pharmacologic methods enhanced radiosensitivity in mul...

Tumor cells are in an adhesion profile during cell-cell and cell-matrix interaction. However, it is challenging for current platforms (e.g., typical droplet systems) to measure MMP9 secreted by single cells in an adhesion profile and retrieve the cells of interest for downstream analysis. Herein, we report a single-cell protease sensor (SCPS) based on ‘...

Fulton, Johannes A. Lercher, Charles T. CampbellAbstractThe mechanisms of aqueous-phase thermal catalytic hydrogenation (TCH) and electrocatalytic hydrogenation (ECH) of organic molecules over Pt group metals are not as well-understood as gas-phase thermal catalytic hydrogenation. In gas-phase, the reactions generally occur via a Langmuir-Hinshelwood mechanism with adsorbed hydrogen adding to adsorbed organics. Here, we ...

In this study, protein-based nanoparticles were constructed with TRAIL and a dipeptide, diphenylalanine (FF), through molecular self-assembly. TRAIL-FF nanoparticles with sizes ranging from 60 nm to 500 nm could be prepared by controlling the concentration and the ratio of the two components. These nanoparticles could locate around the cytomembrane of MCF-7 cells due to the specific interaction between TRAIL and death receptors, thus transduce apoptotic signal. Therefore, the TRAIL-FF nanoparticles showed distinct killing effect on the cancer cells, such as MCF-7 and H460 cells, and the IC50 of the nanopartic...
