The liver produces and secretes sex hormone–binding globulin (SHBG), which transports sex steroids and regulates their access to tissues. Body mass index is a major determinant SHBG concentration in the blood of men and women. Low plasma SHBG levels are associated with obesity and predict the development of type 2 diabetes and cardiovascular disease. The reason why obese individuals have low circulating SHBG has been attributed to hyperinsulinemia, but no mechanistic evi...

Low plasma SHBG levels in overweight individuals are a biomarker for the metabolic syndrome and are predictive of type 2 diabetes and risk of cardiovascular disease. There are no in vivo models to study SHBG expression and regulation during obesity development. The main reason for this is that the obesity-prone rodent models cannot be used to study this issue since rodents unlike humans do not express the SHBG gene in their livers. We have developed by crossi...

Low circulating sex hormone-binding globulin (SHBG) is an independent risk factor for cardiovascular disease. Mediterranean diet has been associated with a decreased risk of cardiovascular disease. We have recently shown that olive oil consumption is associated with elevated SHBG serum levels and that PPARγ downregulation induced by oleoyl-CoA is an important underlying mechanism of such regulation. Red wine is also an important component of the Mediterranean diet and its...

Objective: The objective of our study is to evaluate muscle strength and risk of falls in type 2 diabetes mellitus (DM2) patientsMethods: Observational cross-sectional study. Hand grip strength (HGS) (kg/cm2) was measured with a Jamar. manual hydraulic dynamometer (5030j1; Jackson, MI). To classify normality, data from the Spanish population were used, establishing the cut-off point at p10. To assess the level of mobility and the risk of ...

Low plasmasex hormone-binding globulin (SHBG) levels are present in fatty liver disease, which represents a spectrum of diseases ranging from hepatocellular steatosis through steatohepatitis to fibrosis and irreversible cirrhosis. We are interested in studying the molecular mechanisms by which plasma SHBG levels are reduced in fatty liver disease. In this regard, we have previously shown that fat accumulation in the liver reduces SHBG production by reducing hepatic nuclear fac...

Introduction: Maternally inherited diabetes and deafness (MIDD), is a rare entity. Most commonly, it is related to a point mutation in the mitochondrial DNA (mtDNA) at position 3243 (m.3243A>G) encoding the gene for tRNA. A high index of suspicion is required for the diagnosis due to a wide heterogeneity in its clinical presentation which reflects different levels of mutated mtDNA among mitochondria in a given tissue (heteroplasmy). Thyroid cancer risk has never been speci...

Low plasma sex hormone-binding globulin (SHBG) levels are present in fatty liver disease, which represent a spectrum of diseases ranging from hepatocellular steatosis through steatohepatitis to fibrosis and irreversible cirrhosis. We have previously determined that fat accumulation reduces SHBG production in different non-alcoholic fatty liver disease (NAFLD) mouse models and that SHBG plays an active role in the development of this disease. In the present work, we are interes...

In adult mice the adrenal cortex is divided, in two distinct functional zones, outermost zona glomerulosa (ZG) and innermost zona fasciculata (ZF), encapsulated by a thin layer of mesenchymal cells (capsule). The adrenal cortex undergoes constant centripetal cell renewal, reliying on recruitment of progenitors located within an outer cortex niche. Progenitors initially differentiate as ZG cells and undergo lineage conversion to ZF as they move within the cortex. This relies on...

Background: The complex involvement of multiple metabolic defects in the pathogenesis of type 2 diabetes mellitus (T2DM) makes difficult the treatment in monotherapy, therefore, the use of different antidiabetic drugs with different and complementary mechanisms of action could result in better glycemic control with favorable metabolic changes.Objective: To determine the effectiveness and safety of the addition of a sodium-glucose co-transporter type 2 in...

Background: Cross-sex hormone therapy (CHT) is known to lead to alterations in cardiovascular risk factor(CVRF).Objective: To assess changes in lipid profile and other CVRF in transsexual subjects receiving CHT.Materials and methods: Retrospective longitudinal study. We evaluated individuals with gender identity disorder following CHT, assisted in the Gender Identity Unit from 2015 to 2017. Primary endpoint was lipid profile change...
