<h4>Objective</h4>Regulation of fatty acid (FA) metabolism is central to adipocyte dysfunction during diet-induced obesity (DIO). Long-chain acyl-CoA synthetase-4 (ACSL4) has been hypothesized to modulate the metabolic fates of polyunsaturated FA (PUFA), including arachidonic acid (AA), but the in vivo actions of ACSL4 are unknown. The purpose of our studies was ... Read more >>

Liver-specific reconstitution of CEACAM1 reverses the metabolic abnormalities caused by its global deletion in male mice.

Lucia Russo, Harrison T Muturi, Hilda E Ghadieh, Simona S Ghanem, Thomas A Bowman, Hye Lim Noh, Sezin Dagdeviren, Godwin Y Dogbey, Jason K Kim, Garrett Heinrich, Sonia M Najjar,

<h4>Aims/hypothesis</h4>The carcinoembryonic antigen-related cell adhesion molecule 1 (CEACAM1) promotes insulin clearance. Mice with global null mutation (Cc1 <sup>-/-</sup>) or with liver-specific inactivation (L-SACC1) of Cc1 (also known as Ceacam1) gene display hyperinsulinaemia resulting from impaired insulin clearance, insulin resistance, steatohepatitis and obesity. Because increased lipolysis contributes to the metabolic phenotype ... Read more >>

Thomas A Bowman, Kayleigh R O'Keeffe, Theresa D'Aquila, Qing Wu Yan, John D Griffin, Elizabeth A Killion, Deanna M Salter, Douglas G Mashek, Kimberly K Buhman, Andrew S Greenberg,

<h4>Objective</h4>The family of acyl-CoA synthetase enzymes (ACSL) activates fatty acids within cells to generate long chain fatty acyl CoA (FACoA). The differing metabolic fates of FACoAs such as incorporation into neutral lipids, phospholipids, and oxidation pathways are differentially regulated by the ACSL isoforms. In vitro studies have suggested a role for ... Read more >>

Hepatic CEACAM1 Over-Expression Protects Against Diet-Induced Fibrosis and Inflammation in White Adipose Tissue.

Sumona G Lester, Lucia Russo, Simona S Ghanem, Saja S Khuder, Anthony M DeAngelis, Emily L Esakov, Thomas A Bowman, Garrett Heinrich, Qusai Y Al-Share, Marcia F McInerney, William M Philbrick, Sonia M Najjar,

CEACAM1 promotes insulin extraction, an event that occurs mainly in liver. Phenocopying global Ceacam1 null mice (Cc1(-/-) ), C57/BL6J mice fed a high-fat (HF) diet exhibited reduced hepatic CEACAM1 levels and impaired insulin clearance, followed by hyperinsulinemia, insulin resistance, and visceral obesity. Conversely, forced liver-specific expression of CEACAM1 protected insulin ... Read more >>

FFA-induced hepatic insulin resistance in vivo is mediated by PKCδ, NADPH oxidase, and oxidative stress.

Fat-induced hepatic insulin resistance plays a key role in the pathogenesis of type 2 diabetes in obese individuals. Although PKC and inflammatory pathways have been implicated in fat-induced hepatic insulin resistance, the sequence of events leading to impaired insulin signaling is unknown. We used Wistar rats to investigate whether PKCδ ... Read more >>

Perilipin-2-null mice are protected against diet-induced obesity, adipose inflammation, and fatty liver disease.

James L McManaman, Elise S Bales, David J Orlicky, Matthew Jackman, Paul S MacLean, Shannon Cain, Amanda E Crunk, Ayla Mansur, Christine E Graham, Thomas A Bowman, Andrew S Greenberg,

The cytoplasmic lipid droplet (CLD) protein perilipin-2 (Plin2) is expressed in multiple nonadipose tissues, where it is thought to play a role in regulating their lipid storage properties. However, the extent to which Plin2 functions in nutrient utilization and metabolism, or how it influences the consequences of over-feeding, remains unclear. ... Read more >>

Thomas A Bowman, Sadeesh K Ramakrishnan, Meenakshi Kaw, Sang Jun Lee, Payal R Patel, Varun K Golla, Raymond E Bourey, Per Magnus Haram, Lauren G Koch, Steven L Britton, Ulrik Wisløff, Abraham D Lee, Sonia M Najjar,

Rats selectively bred for low aerobic running capacity exhibit the metabolic syndrome, including hyperinsulinemia, insulin resistance, visceral obesity, and dyslipidemia. They also exhibit features of nonalcoholic steatohepatitis, including chicken-wire fibrosis, inflammation, and oxidative stress. Hyperinsulinemia in these rats is associated with impaired hepatic insulin clearance. The current studies aimed to ... Read more >>

Mice with null mutation of Ceacam I develop nonalcoholic steatohepatitis.

Sumona Ghosh, Meenakshi Kaw, Payal R Patel, Kelly J Ledford, Thomas A Bowman, Marcia F McInerney, Sandra K Erickson, Raymond E Bourey, Sonia M Najjar,

Transgenic liver-specific inactivation of the carcinoembryonic antigen-related cell adhesion molecule (CEACAM1) impairs hepatic insulin clearance and causes hyperinsuline-mia, insulin resistance, elevation in hepatic and serum triglyceride levels, and visceral obesity. It also predisposes to nonalchoholic steatohepatitis (NASH) in response to a high-fat diet. To discern whether this phenotype reflects a ... Read more >>

Manya Warrier, Terry D Hinds, Kelly J Ledford, Harrison A Cash, Payal R Patel, Thomas A Bowman, Lance A Stechschulte, Weidong Yong, Weinian Shou, Sonia M Najjar, Edwin R Sanchez,

Although FK506-binding protein 52 (FKBP52) is an established positive regulator of glucocorticoid receptor (GR) activity, an in vivo role for FKBP52 in glucocorticoid control of metabolism has not been reported. To address this question, FKBP52(+/-) mice were placed on a high-fat (HF) diet known to induce obesity, hepatic steatosis, and ... Read more >>

Anthony M DeAngelis, Garrett Heinrich, Tong Dai, Thomas A Bowman, Payal R Patel, Sang Jun Lee, Eun-Gyoung Hong, Dae Young Jung, Anke Assmann, Rohit N Kulkarni, Jason K Kim, Sonia M Najjar,

<h4>Objective</h4>Liver-specific inactivation of carcinoembryonic antigen-related cell adhesion molecule 1 (CEACAM1) by a dominant-negative transgene (l-SACC1 mice) impaired insulin clearance, caused insulin resistance, and increased hepatic lipogenesis. To discern whether this phenotype reflects a physiological function of CEACAM1 rather than the effect of the dominant-negative transgene, we characterized the metabolic phenotype ... Read more >>
