Project description:RNAseq analysis of USP7 conditional knock-out (cKO) mice. They were designed to flox exon 6 of USP7 and to allow deletion of exon 6 upon expression of Cre recombinase 27. USP7FL/FL mice were bred with Vav1-Cre mice to obtain USP7FL/wt-Vav1-Cre mice (heterozygote). USP7FL/FL-Vav1-Cre mice (homozygote) were obtained via breeding of heterozygous cKO mice.

Project description:Villin-Cre+ Lsd1fl/fl (cKO) mice display an immature intestinal epithelium characterized by an incomplete differentiation of enterocytes and secretory lineages, reduced number of goblet cells and a complete loss of Paneth cells. This experiment aims to elucidate the differences in stool microbial composition derived from WT (Villin-Cre- Lsd1fl/fl) and cKO mice both in adult (2-month-old) and neonatal (14 days postpartum P14) stages. Different timepoints are crucial to understand the role of intestinal maturation in microbiome composition since said maturation is dependent on time-dependent external cues happening at P14-21 (weaning and transition from milk to solid foods).

Project description:We have previously shown that the HyD-LIR-Venus probe can specifically inhibit selective autophagy by suppressing the interaction of LIR-containing selective autophagy substrates and receptors with ATG8-family proteins in vivo. We generated hepatocyte-specific HyD-LIR-Venus-expressing mice (HyD-LIRflox/flox; Alb-Cre) by crossing HyD-LIRflox/flox mice, in which HyD-LIR-Venus is expressed under CAG promoter in a Cre-recombinase-dependent manner, with Alb-Cre transgenic mice that express Cre under the control of the Albumin promoter. We performed quantitative proteomic analysis of the livers of 5-week-old HyD-LIRflox/flox and HyD-LIRflox/flox; Alb-Cre mice using the RTS-SPS-MS3 method on Tribrid mass spectrometry.

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:Human milk oligosaccharides (HMOs) are highly diverse complex carbohydrates secreted in human milk. HMOs are indigestible by the infant and instead are metabolized by bifidobacteria in the infant gut microbiome to produce molecules that promote infant health and development. 2´fucosyllactose (2´FL) is an abundant HMO and is utilized by Bifidobacterium longum subsp. infantis, a predominant member of the infant gut microbiome. Currently, there is not a scientific consensus on how or if bifidobacteria metabolize the fucose portion of 2´FL or free fucose. This proteomic analysis was conducted in order to characterize the metabolic pathway by which B. infantis utilizes fucose.

Project description:This quantitative protepomics study (TMT10 isobaric labeling) of the protein expression in the retina of Msi1/Msi2 double knockout mouse compared to floxed controls. The Msi1 and Msi2 genes were knocked out in photoreceptor cells using tamoxifen inducible Cre (Cre-ERT2) under the control of Pde6g promoter. Tamoxifen was administered by intrapertoneal injection for three consecutive day starting at postnatald day 30, and the retina was collected at postnatal day 51. Retinas from floxed animals lacking the Cre recombinase and treated with tamoxifen were used as controls. Five biological replicates for each knockout (three femailes, two males) and control (two femaes and three males) group were used.

Project description:In this study mice were engineered to specifically delete Twist1 or Snail expression in proximal tubular epithelial cells of the kidney (ggt-cre+;Twist flox/flox and ggt-cre+;Snail flox/flox ). These mice and control mice (ggtcre-;Twist flox/flox: these express Twist1, and ggtcre-;Snail flox/flox:these express Snail) were subjected to unilaterial ureteric obstruction. This experiment allows for the collection and analysis of expression in contralateral healthy (HK) kidney adn obstructed disease (DK) kidney. Total RNA was isolated from the contralateral healthy (HK) and obstructed disease (DK) kidneys of 3 mice with ggt-cre-;Twist flox/flox genotype (Wildtype like) and 4 mice with ggt-cre+;Twist flox/flox genotype (loss of Twist1 in proximal tubular epithelial cells), 3 mice with ggt-cre-;Snail flox/flox genotype (Wildtype like) and 3 mice with ggt-cre+;Snail flox/flox genotype (loss of Snail in proximal tubular epithelial cells). Total RNA was also isolated from kidneys of completely healthy mice: 3 mice ggt-cre-;WT, 3 mice ggt-cre+;WT, 3 mice ggt-cre+;Twist flox/flox and 3 ggt-cre+;Snail flox/flox

Project description:In order to determine the dependency of mature tissue-resident ILCs on combinations of synergistic and antagonising Transcription Factors (TFs), we generated mice with conditional deletions of RORc, RORa and Tbx21 driven from the Id2 allele, utilizing a tamoxifen inducible Cre-recombinase in combination with a tdRFP allele to report Cre-excision (Id2creERT2 x ROSAtdRFP). RFP+ small intestinal ILCs were sorted from the lamina propria digests (gated as CD45+, Lineage negative, CD90+ CD127+, tdRFP+ - see manuscript for full methodological details), from control mice or mice containing loxP flanked alleles for RORc, RORc and RORa or RORc and Tbx21. Four samples of sort-purified ILCs were then subjected to 10X single cell sequencing; - Id2creERT2 - Id2idRORc - Id2idRORc/RORa - Id2idRORc/Tbx21
