Project description:SOCS2 Ensures Metabolic Function and Mass Restoration During Liver Regeneration - SOCS2 plays distinct and contrasting roles during liver regeneration. Early after injury, SOCS2 expression increases and limits the rate of regeneration, preserving metabolic activity. Surprisingly, at later times, the role of SOCS2 reverses to promote liver regeneration by stimulating GH release from the pituitary via effects on serum levels of insulin-like growth factor 1. Loss of SOCS2 promotes GH signaling by increasing growth hormone receptor levels and driving phosphorylation of proteins in the GH pathway, establishing a state of hyper-responsiveness to GH. These findings suggest a single protein can play contrasting roles at different times after liver injury and modulation of GH signaling achieves an optimal rate of liver regeneration to balance metabolic and restorative needs. To further understand the mechanism by which SOCS2 increases early liver regeneration, we performed microarray analysis of Socs2-null mice wildtype mice at 24 and 36 hours after hepatectomy. C57BL/6 mice where used as wildtype controls. Socs2-null animals were maintained on a C57BL/6 background. Both wildtype and Socs2-null adult mice were subjected to 2/3 hepatectomy and liver tissue isolated at 24 hours and 36 hours post hepatectomy. Time zero was without hepatectomy in age-matched mice for each genotype. Total RNA isolated from collected liver tissues was pooled for three animals at each time point and two biological replicates (3 pooled liver RNAs each) were labeled for array analysis. This results in a total of 12 microarrays.

Project description:The ketogenic diet has been successful in promoting weight loss among patients that have struggled with weight gain. This is due to the cellular switch in metabolism that utilizes liver-derived ketone bodies for the primary energy source rather than glucose. Fatty acid transport protein 2 (FATP2) is highly expressed in liver, small intestine, and kidney where it functions in both the transport of exogenous long chain fatty acids (LCFA) and in the activation to CoA thioesters of very long chain fatty acids (VLCFA). We have completed a multi-omic study of FATP2-null (Fatp2-/-) mice maintained on a ketogenic diet (KD) or paired control diet (CD), with and without a 24-hour fast (KD-fasted and CD-fasted) to address the impact of deleting FATP2 under high-stress conditions. Control (wt/wt) and Fatp2-/- mice were maintained on their respective diets for 4-weeks. Afterwards, half the population was sacrificed while the remaining were fasted for 24-hours prior to sacrifice. We then performed paired-end RNA-sequencing on the whole liver tissue to investigate differential gene expression. The differentially expressed genes mapped to ontologies such as the metabolism of amino acids and derivatives, fatty acid metabolism, protein localization, and components of the immune system’s complement cascade, and were supported by the proteome and histological staining.
