PMID: 26977389
Mol Metab. 2015 Dec 25;5(3):184-197. doi: 10.1016/j.molmet.2015.12.002. eCollection 2016 Mar.

OBJECTIVES: Chronic and high consumption of fat constitutes an environmental stress that leads to metabolic diseases. We hypothesized that high-fat diet (HFD) transgenerationally remodels the epigenome of spermatozoa and metabolism of the offspring.METHODS: F0-male rats fed either HFD or...

EBF2 promotes the recruitment of beige adipocytes in white adipose tissue.

Molecular metabolism

Stine RR, Shapira SN, Lim HW, Ishibashi J, Harms M, Won KJ, Seale P.
PMID: 26844207
Mol Metab. 2015 Nov 14;5(1):57-65. doi: 10.1016/j.molmet.2015.11.001. eCollection 2016 Jan.

OBJECTIVE: The induction of beige/brite adipose cells in white adipose tissue (WAT) is associated with protection against high fat diet-induced obesity and insulin resistance in animals. The helix-loop-helix transcription factor Early B-Cell Factor-2 (EBF2) regulates brown adipose tissue development....

Decreased expression of hepatic glucokinase in type 2 diabetes.

Molecular metabolism

Haeusler RA, Camastra S, Astiarraga B, Nannipieri M, Anselmino M, Ferrannini E.
PMID: 25737948
Mol Metab. 2014 Dec 18;4(3):222-6. doi: 10.1016/j.molmet.2014.12.007. eCollection 2015 Mar.

BACKGROUND/OBJECTIVES: Increased endogenous glucose production is a hallmark of type 2 diabetes. Evidence from animal models has suggested that a likely cause of this is increased mRNA expression of glucose 6-phosphatase and phosphoenolpyruvate carboxykinase (encoded by G6PC, PCK1 and...

Leptin recruits Creb-regulated transcriptional coactivator 1 to improve hyperglycemia in insulin-deficient diabetes.

Molecular metabolism

Kim GH, Szabo A, King EM, Ayala J, Ayala JE, Altarejos JY.
PMID: 25737949
Mol Metab. 2014 Dec 19;4(3):227-36. doi: 10.1016/j.molmet.2014.12.006. eCollection 2015 Mar.

OBJECTIVE: Leptin alleviates hyperglycemia in rodent models of Type 1 diabetes by activating leptin receptors within the central nervous system. Here we delineate whether non-canonical leptin signaling through the Creb-regulated transcriptional coactivator 1 (Crtc1) contributes to leptin-dependent improvements in...

Metabolic modeling of muscle metabolism identifies key reactions linked to insulin resistance phenotypes.

Molecular metabolism

Nogiec C, Burkart A, Dreyfuss JM, Lerin C, Kasif S, Patti ME.
PMID: 25737951
Mol Metab. 2015 Jan 02;4(3):151-63. doi: 10.1016/j.molmet.2014.12.012. eCollection 2015 Mar.

OBJECTIVE: Dysregulated muscle metabolism is a cardinal feature of human insulin resistance (IR) and associated diseases, including type 2 diabetes (T2D). However, specific reactions contributing to abnormal energetics and metabolic inflexibility in IR are unknown.METHODS: We utilize flux balance...

High-calorie diet exacerbates prostate neoplasia in mice with haploinsufficiency of Pten tumor suppressor gene.

Molecular metabolism

Liu J, Ramakrishnan SK, Khuder SS, Kaw MK, Muturi HT, Lester SG, Lee SJ, Fedorova LV, Kim AJ, Mohamed IE, Gatto-Weis C, Eisenmann KM, Conran PB, Najjar SM.
PMID: 25737954
Mol Metab. 2015 Jan 02;4(3):186-98. doi: 10.1016/j.molmet.2014.12.011. eCollection 2015 Mar.

OBJECTIVE: Association between prostate cancer and obesity remains controversial. Allelic deletions of PTEN, a tumor suppressor gene, are common in prostate cancer in men. Monoallelic Pten deletion in mice causes low prostatic intraepithelial neoplasia (mPIN). This study tested the...

Activation of NF-κB drives the enhanced survival of adipose tissue macrophages in an obesogenic environment.

Molecular metabolism

Hill AA, Anderson-Baucum EK, Kennedy AJ, Webb CD, Yull FE, Hasty AH.

Mol Metab. 2015 Jul 28;4(10):665-77. doi: 10.1016/j.molmet.2015.07.005. eCollection 2015 Oct.

OBJECTIVE: Macrophage accumulation in adipose tissue (AT) during obesity contributes to inflammation and insulin resistance. Recruitment of monocytes to obese AT has been the most studied mechanism explaining this accumulation. However, recent evidence suggests that recruitment-independent mechanisms may also...

Glucose intolerance induced by blockade of central FGF receptors is linked to an acute stress response.

Molecular metabolism

Mol Metab. 2015 Jun 04;4(8):561-8. doi: 10.1016/j.molmet.2015.05.005. eCollection 2015 Aug.

OBJECTIVE: Central administration of ligands for fibroblast growth factor receptors (FGFRs) such as fibroblast growth factor-19 (FGF19) and FGF21 exert glucose-lowering effects in rodent models of obesity and type 2 diabetes (T2D). Conversely, intracerebroventricular (icv) administration of the non-selective...

Mol Metab. 2016 Jun 10;5(8):656-668. doi: 10.1016/j.molmet.2016.05.015. eCollection 2016 Aug.

OBJECTIVE: Insulin release from pancreatic islet β cells should be tightly controlled to avoid hypoglycemia and insulin resistance. The cortical actin cytoskeleton is a gate for regulated exocytosis of insulin secretory granules (SGs) by restricting their mobility and access...
