Project description:The liver is composed of various resident cells, including hepatocytes, Kupffer cells, liver sinusoidal endothelial cells (LSEC), and hepatic stellate cells (HSC). Hepatocytes are the primary type of liver cells, constituting 80% of the liver's mass, and are responsible for tasks such as protein and lipid synthesis, detoxification, and bile secretion. Kupffer cells, on the other hand, are liver-resident macrophages that play a crucial role in detecting foreign antigens and danger signals within the liver, as well as clearing apoptotic cells. LSEC is in charge of blood vessel formation in the liver and is responsible for eliminating cell debris. In the quiescent state, HSC stores vitamin A and is essential in liver fibrosis when activated. Freshly isolated HSCs undergo automatic activation upon culture. In this study, we present microarray data for freshly isolated mouse hepatocytes, Kupffer cells and LSEC, along with HSCs that have been cultured for 1, 7 or 14 days.
Project description:We show that macrophages from murine spleen, liver and peritoneum display dramatically different expression profiles. Clusters of genes were found to represent unique biological functions related to adhesion, antigen presentation, phagocytosis, lipid metabolism and signal transduction. Some gene families, such as integrins, are differentially expressed among the macrophages resident in different tissues, suggesting that the tissue of residence influences their biological function. 18 FACS sorted mouse tissue-resident macrophge samples. 6 cell types, 3 biological replicates per cell type.
Project description:RNA transcriptome data from C57BL/6 tissue resident peritoneal macrophages over expressing microRNA 708 or control. The role of microRNA-708 in shaping macrophage biology remains mostly unknown. Here, using lentiviral vectors we overexpressed microRNA-708 in vivo in C57BL/6 mice peritoneal macrophages and investigated mRNA changes in these cells after 4 days.
Project description:Sequencing files provided here are mouse liver ChIP-seq for the activating histone mark H3K27ac in two mouse strains: C57BL/6J and CAST/EiJ. This is part of a larger study published in PLoS Genetics (2021) "Harnessing natural variation to identify cis regulators of sex-biased gene expression in a multi-strain mouse liver model" that includes RNA-seq and DNase-seq in mouse liver from the same two strains. This allows us to identify strain-shared ("core") and strain-unique sex-biased genes and enhancers.

Project description:Liver macrophages play a major role in the control of infections in the liver and in the pathology associated with chronic liver diseases. It was recently shown that liver macrophages can have two different origins, however, the extent to which these populations are functionally distinct remains to be fully addressed. In this study, we compare the gene expression profile of liver resident and bone marrow derived liver macrophages in mouse, 6 weeks after total body irradiation and bone marrow transplantation.
