    Role of Endoplasmic Reticulum-Mitochondria Communication in Type 2 Diabetes.
    Adv Exp Med Biol 2017 ;997:171-186
    Faculté de médecine Lyon-Sud, UMR INSERM U1060, CarMeN Laboratory, Lyon 1 University, INRA U1397, 165 chemin du grand Revoyet, BP12, F-69921, Oullins Cedex, France.
    Although mitochondrial dysfunction, endoplasmic reticulum (ER) stress, and disrupted lipid and calcium (Ca(2+)) homeostasis are classically associated with both insulin resistance and β-cell dysfunction in type 2 diabetes mellitus (T2DM), the interplay between these metabolic stresses is less known. Both organelles interact through contact points known as mitochondria-associated membranes (MAM), in order to exchange both lipids and Ca(2+) and regulate cellular homeostasis. Recent evidences suggest that MAM could be an important hub for hormonal and nutrient signaling in the liver and that ER-mitochondria miscommunication could participate to hepatic insulin resistance, highlighting the importance of MAM in the control of glucose homeostasis.

    Insulin-Like Growth Factor (IGF) Pathway Targeting in Cancer: Role of the IGF Axis and Opportunities for Future Combination Studies.
    Target Oncol 2017 Aug 16. Epub 2017 Aug 16.
    Boehringer Ingelheim RCV, Dr. Boehringer Gasse 5-11, 1121, Vienna, Austria.
    Despite a strong preclinical rationale for targeting the insulin-like growth factor (IGF) axis in cancer, clinical studies of IGF-1 receptor (IGF-1R)-targeted monotherapies have been largely disappointing, and any potential success has been limited by the lack of validated predictive biomarkers for patient enrichment. A large body of preclinical evidence suggests that the key role of the IGF axis in cancer is in driving treatment resistance, via general proliferative/survival mechanisms, interactions with other mitogenic signaling networks, and class-specific mechanisms such as DNA damage repair. Consequently, combining IGF-targeted agents with standard cytotoxic agents, other targeted agents, endocrine therapies, or immunotherapies represents an attractive therapeutic approach. Read More

    Importance of adiponectin activity in the pathogenesis of Alzheimer's disease.
    Ann Clin Transl Neurol 2017 Aug 11;4(8):591-600. Epub 2017 Jul 11.
    Tokyo Metropolitan Institute of Medical Science2-1-6 KamikitazawaSetagaya-kuTokyo156-8506Japan.
    A recent study suggested that insulin resistance may play a central role in the pathogenesis of Alzheimer's disease (AD). In this regard, it is of note that upregulation of plasma adiponectin (APN), a benign adipokine that sensitizes the insulin receptor signaling pathway and suppresses inflammation, has recently been associated with the severities of amyloid deposits and cognitive deficits in the elderly, suggesting that APN may enhance the risk of AD. These results are unanticipated because AD has been linked to type II diabetes and other metabolic disorders in which hypoadiponectinemia has been firmly established, and because APN ameliorated neuropathological features in a mouse model of neurodegeneration.

    Non-alcoholic fatty liver disease and non-alcoholic steatohepatitis are characterized by an increase in hepatic triglyceride content with infiltration of immune cells, which can cause steatohepatitis and hepatic insulin resistance. C-C chemokine receptor 7 (CCR7) is primarily expressed in immune cells, and CCR7 deficiency leads to the development of multi-organ autoimmunity, chronic renal disease, and autoimmune diabetes. Here, we investigated the effect of CCR7 on hepatic steatosis in a mouse model and its underlying mechanism. Read More

    Insulin action and glucose disposal are enhanced by exercise, yet the mechanisms involved remain imperfectly understood. While the causes of skeletal muscle insulin resistance also remain poorly understood, new evidence suggest excess plasma membrane (PM) cholesterol may contribute by damaging the cortical filamentous actin (F-actin) structure essential for GLUT4 glucose transporter redistribution to the PM upon insulin stimulation. Here, we investigated whether PM cholesterol toxicity was mitigated by exercise. Read More

    Fasting insulin, insulin resistance and risk of cardiovascular or all-cause mortality in non-diabetic adults: a meta-analysis.

    Studies on elevated fasting insulin or insulin resistance (IR) and cardiovascular or all-cause mortality risk in non-diabetic individuals have yielded conflicting results. This meta-analysis aimed to evaluate the association of elevated fasting insulin levels or insulin resistance as defined by homeostasis model assessment of insulin resistance (HOMA-IR) with cardiovascular or all-cause mortality in non-diabetic adults. We searched for relevant studies in PubMed and Emabse databases until November 2016. Read More

    The soluble receptor for advanced glycation endproducts (sRAGE) may be protective against inflammation associated with obesity and type 2 diabetes (T2DM). The aim of this study was to determine the distribution of sRAGE isoforms, and whether sRAGE isoforms are associated with risk of T2DM development in subjects spanning the glucose tolerance continuum. In this retrospective analysis, circulating total sRAGE and endogenous secretory RAGE (esRAGE) were quantified via ELISA and cleaved RAGE (cRAGE) was calculated in 274 individuals stratified by glucose tolerance status (GTS) and obesity.

    Skeletal muscle insulin resistance is the hallmark of type 2 diabetes, and develops long before the onset of the disease. It is well accepted that physical activity improves glycemic control but the knowledge on underlying mechanisms mediating the beneficial effects remains incomplete. Exercise is accompanied by a decrease in intramuscular oxygen levels resulting in induction of HIF-1α. Read More
