Project description:Pancreatic cancer is the 3rd most prevalent cause of cancer related deaths in United states alone, with over 55000 patients being diagnosed in 2019 alone and nearly as many succumbing to it. Late detection, lack of effective therapy and poor understanding of pancreatic cancer systemically contributes to its poor survival statistics. Obesity and high caloric intake linked co-morbidities like type 2 diabetes (T2D) have been attributed as being risk factors for a number of cancers including pancreatic cancer. Studies on gut microbiome has shown that lifestyle factors as well as diet has a huge effect on the microbial flora of the gut. Further, modulation of gut microbiome has been seen to contribute to effects of intensive insulin therapy in mice on high fat diet. In another study, abnormal gut microbiota was reported to contribute to development of diabetes in Db/Db mice. Recent studies indicate that microbiome and microbial dysbiosis plays a role in not only the onset of disease but also in its outcome. In colorectal cancer, Fusobacterium has been reported to promote therapy resistance. Certain intra-tumoral bacteria have also been shown to elicit chemo-resistance by metabolizing anti-cancerous agents. In pancreatic cancer, studies on altered gut microbiome have been relatively recent. Microbial dysbiosis has been observed to be associated with pancreatic tumor progression. Modulation of microbiome has been shown to affect response to anti-PD1 therapy in this disease as well. However, most of the studies in pancreatic cancer and microbiome have remained focused om immune modulation. In the current study, we observed that in a T2D mouse model, the microbiome changed significantly as the hyperglycemia developed in these animals. Our results further showed that, tumors implanted in the T2D mice responded poorly to Gemcitabine/Paclitaxel (Gem/Pac) standard of care compared to those in the control group. A metabolomic reconstruction of the WGS of the gut microbiota further revealed that an enrichment of bacterial population involved in drug metabolism in the T2D group.

Project description:The microbiome plays a significant role in gut brain communication and is linked to several animal and human diseases. Hypertension is characterized by gut dysbiosis, and this study aimed to determine how the gut microbiome differed between male and female normotensive and hypertensive rodents. WKY is a genetic control for spontaneous hypertensive rats or SHR which is well documented to have elevated blood pressure at approximately 8 to 10 weeks. We compared the microbiome of normotensive and hypertensive rodents using a meta-genomics approach.

Project description:This project study and comprehensively characterize the lysine acetyltion in the human gut microbiome using antibody-based enrichment strategry and Orbitrap mass spectrometer. The technique has also been applied to study the microbiome in pediatric Crohn's disease and control subjects in order to understand the functional alterations of microbiome in IBD.

Project description:Nutrition has a vital role in shaping the intestinal microbiome. The impact of nutrients and the consequences of enteral deprivation on the small intestinal mucosal microbiota, specifically in early life, has not been well described. Our aim was to study the impact of enteral deprivation on the small intestine mucosal microbiome and to search for factors that shape this interaction in early life. Host seem to be the most dominant factor in the structure of the early life mucosal microbial small intestine community. Under conditions of nutrient deprivation, there are specific changes in host proteomics. Further research is needed to better define and understand this host-microbe-nutrition interaction in the small intestine.

Project description:Microarray analysis of HT-29 cells co-cultured with tumor necrosis factor (TNF-a) in the presence or absence of polymeric formula as used for Exclusive Enteral Nutrition (EEN) therapy. Results provide insights into the molecular mechanisms underlying the anti-inflammatory effect of polymeric formula on intestinal epithelium.

Project description:Opioid analgesics are frequently prescribed in the United States and worldwide. However, serious side effects such as addiction, immunosuppression and gastrointestinal symptoms limit long term use. In the current study using a chronic morphine-murine model a longitudinal approach was undertaken to investigate the role of morphine modulation of gut microbiome as a mechanism contributing to the negative consequences associated with opioids use. The results revealed a significant shift in the gut microbiome and metabolome within 24 hours following morphine treatment when compared to placebo. Morphine induced gut microbial dysbiosis exhibited distinct characteristic signatures profiles including significant increase in communities associated with pathogenic function, decrease in communities associated with stress tolerance. Collectively, these results reveal opioids-induced distinct alteration of gut microbiome, may contribute to opioids-induced pathogenesis. Therapeutics directed at these targets may prolong the efficacy long term opioid use with fewer side effects.

Project description:Microarray analysis of HT-29 cells co-cultured with tumor necrosis factor (TNF-a) in the presence or absence of polymeric formula as used for Exclusive Enteral Nutrition (EEN) therapy. Results provide insights into the molecular mechanisms underlying the anti-inflammatory effect of polymeric formula on intestinal epithelium. Total RNA obtained from 9 samples of HT-29 cells. Six samples were treated with TNF-a in the presence (3 samples) or absence (3 samples) of Polymeric Formula. Three samples were untreated and used as a control.
