Project description:The goal of this experiment was to distinguish those genes regulated following acute HNF4alpha depletion compared to a developmental knockout model where gene compensation may comfound results. Expression profile of livers from 8 week old male Hnf4alpha Flox mice that express either albumin cre or the tamoxifen inducible ErT2-albumin cre for liver-specific deletion. Mice were fed a control diet or tamoxifen diet in the case of the ErT2-albumin cre to induce recombination.
Project description:The total abundance of phosphatidylcholine (PC) is known to influence lipoprotein production. However, the role of specific phospholipid species in lipid transport has been difficult to assess due to an inability to selectively manipulate membrane composition in vivo. Here we show that the LXR-regulated phospholipid remodeling enzyme lysophosphatidylcholine acyltransferase 3 (Lpcat3) is a critical determinant of membrane phospholipid composition and lipoprotein production. Mice lacking Lpcat3 in the liver show defects in lipoprotein production. The objective of generating this dataset was to analyze the effects of Lpcat3 loss of function on gene expression in mouse liver with a western diet challenge. This dataset compares gene expression in Lpcat3fl/fl and Lpcat3fl/fl Albumin-Cre liver samples from 16-week old male mice that were fed a western diet for 9 weeks since 7 weeks old. Each sample contains tissues from 5 mice.

Project description:Metabolic-associated steatohepatitis (MASH), the inflammatory stage of MASLD, will soon be one of the primary causes of liver-related complications, including advanced fibrosis and hepatocellular carcinoma. Its steady increase in both the US and the global population is devastating. Between the two genders, more women are suffering from MASH compared to the man due to estrogen deficiency caused by polycystic ovary syndrome or menopause. Our published data shows a clear positive association between the progression of liver disease and the expression of novel hexokinase HKDC1 in the liver. Targeting HKDC1, which is highly expressed in pathological hepatocytes (in MASH) but negligible in normal hepatocytes, represents a highly selective approach. Therefore, we hypothesized that liver-specific deletion of HKDC1 will protect against diet-induced obesity and the progression of MASH to fibrosis. We used an early-onset liver knockout (LKO) of HKDC1 by crossing HKDC1 floxed mice with Albumin Cre mice to test our hypothesis. We fed the Western Diet to HKDC1LKO female mice along with HKDC1 floxed mice (HKDC1fl/fl; as Controls) for 28 weeks. Our data shows that HKDC1 deletion significantly decreases body weight and fat mass compared to HKDC1fl/fl mice with no changes in food intake and energy expenditure. Knockout mice have better glucose tolerance and lower fasting glucose levels than HKDC1fl/fl mice. Our data also shows that the knockout group has smaller livers, healthier liver parameters, less steatosis, and lower NAS and fibrosis scores. Furthermore, HKDC1 knockout alters hepatic gene expression, and we found significantly low proinflammatory and profibrogenic gene expression in the LKO mice. Although we did not see any changes in triglyceride levels, there was a significant reduction of serum cholesterol concomitant with enhanced expression of cholesterol metabolism genes in the knockout group. Our data suggest a promising protective role of HKDC1 deletion against diet-induced obesity and MASH mice.
Project description:To define the regulatory role of Sox9 in intrahepatic biliary epithelium, we conducted bulk RNA-seq on biliary epithelial cells (BECs) from adult control (Sox9fl/fl) and conditional Sox9 knockout (Sox9cKO; Sox9fl/fl:Albumin-Cre) mice. Livers were dissociated to single cells and BECs isolated by FACS based on CD326 positivity. CD31+ and CD45+ cells were excluded by FACS. Gallbladder and extrahepatic tissues were excluded by dissection. RNA was isolated using Ambion RNAqueous Micro kit and libraries were made using Takara SMARTer Stranded Total RNA-seq Kit v3 Pico.
