Project description:Specific expression lipoprotein lipase in adipose by the adiponectin promoter alters the transcriptional response of adipose tissue to an acute high fat diet challenge. We include transcriptional changes in adipose tissue from 12 littermate control and 12 AdipoQ-LpL mice. Gene expression and alternative splicing were analyzed.

Project description:Lipoprotein lipase (LPL) is responsible for the intravascular catabolism of triglyceride-rich lipoproteins and plays a central role in whole-body energy balance and lipid homeostasis. As such, LPL is subject to tissue-specific regulation in different physiological conditions, but the mechanisms of this regulation remain incompletely characterized. Previous work revealed that LPL comprises a set of proteoforms with different isoelectric points, but their regulation and functional significance have not been studied thus far. Here we studied the distribution of LPL proteoforms in different rat tissues and their regulation under physiological conditions. First, analysis by two-dimensional electrophoresis and Western blot showed different patterns of LPL proteoforms (i.e., different pI or relative abundance of LPL proteoforms) in different rat tissues under basal conditions, which could be related to the tissue-specific regulation of the enzyme. Next, the comparison of LPL proteoforms from heart and brown adipose tissue between adults and 15-day-old rat pups, two conditions with minimal regulation of LPL in these tissues, yielded virtually the same tissue-specific patterns of LPL proteoforms. In contrast, the pronounced down-regulation of LPL activity observed in white adipose tissue during fasting is accompanied by a prominent reconfiguration of the LPL proteoform pattern. Furthermore, refeeding reverts this down-regulation of LPL activity and restores the pattern of LPL proteoforms in this tissue. Importantly, this reversible proteoform-specific regulation during fasting and refeeding indicates that LPL proteoforms are functionally diverse. Further investigation of potential differences in the functional properties of LPL proteoforms showed that all proteoforms exhibit lipolytic activity and have similar heparin-binding affinity, although other functional aspects remain to be investigated. Overall, this study demonstrates the ubiquity, differential distribution and specific regulation of LPL proteoforms in rat tissues and underscores the need to consider the existence of LPL proteoforms for a complete understanding of LPL regulation under physiological conditions.

Project description:Sel1L is an adaptor protein for the E3 ligase Hrd1 in the endoplasmic reticulum-associated degradation (ERAD), but its physiological role in a cell-type-specific manner remains unclear. Here we show that mice with adipocyte-specific Sel1L deficiency are resistant to diet-induced obesity and exhibit postprandial hypertriglyceridemia. Mechanistically, our data demonstrate a critical requirement of Sel1L for the secretion of lipoprotein lipase (LPL), independently of its role in Hrd1-mediated ERAD and ER homeostasis. Further biochemical analyses revealed that Sel1L physically interacts and stabilizes the LPL maturation complex consisted of LPL and lipase-maturation factor 1 (LMF1). In the absence of Sel1L, LPL is retained in the ER and prone to the formation of protein aggregates, which are degraded by autophagy-mediated degradation. The Sel1L-mediated control of LPL secretion is seen in other LPL-expressing cell types as well such as cardiac muscle and macrophages. Thus, our study reports a novel role of Sel1L in LPL secretion and systemic lipid metabolism. Sel1Lflox/flox mice were crossed with adiponectin promoter driven Cre mice to create adipose tissue-specific Sel1L-/- mice. Male wildtype C57Bl/6 mice and adipose tissue-specific Sel1l-/- mice were fed a high fat diet (Research Diets D12492) for 5 weeks. Adipose tissue was excised and used for microarray analysis.

Project description:Adipose tissue gene expression was profiled from perigonadal adipose tissue of mice whose body mass and insulin sensitivity varied as a function of diet, gender, monogenic mutations and insulin sensitizing therapies. Mice were 22-24 weeks of age and sacrificed between 2-3 hours into the light portion of a 12/12 dark-light cycle. The goal was to identify transcripts whose adipose tissue expression is correlated with adiposity, insulin sensitivity and other measures of metabolic function. Experiment Overall Design: Mice on the C57BL/6J strain were housed in groups of 3-5 and fed ad libitum. 2-4 days prior to collection of adipose tissue fasting blood glucose and serum insulin concentrations were measured. Mice were sacrificed 2-3 hours into the light cycle. RNA was extracted from perigonadal adipose tissue and used to generate labed cRNA for hybridization to Affymetrix Mu74Av2 microarrays.

Project description:Age-related changes in macrophages are thought to underlie deleterious changes in adipose tissue during aging. RNAseq analysis of phagocyte-enriched and -depleted stromal vascular fractions of perigonadal white adipose tissue from young and aged mice revealed age-related differences in gene expression towards identification of adipose tissue macrophage-specific regulation.
