Differential Expression of FXR and Genes Involved in Inflammation and lipid Metabolism Indicate Adipose Tissue Dysfunction in Gestational Diabetes.

Arch Med Res

April 2023

Unidad de Investigación Médica en Enfermedades Endocrinas, Hospital de Especialidades, Centro Médico Nacional Siglo XXI, Instituto Mexicano del Seguro Social, Ciudad de México, México. Electronic address:

Background: Gestational diabetes mellitus (GDM) is the most frequent metabolic alteration in pregnancy. Several abnormalities in visceral adipose tissue (VAT) have been described as part of its pathophysiology including hypertrophy, inflammation and altered lipid metabolism. Farnesoid X receptor (FXR) is involved in adipocyte physiology and inflammation, so its expression may correlate with the expression of tumor necrosis factor-alpha (TNF-α), interleukin-10 (IL-10), lipoprotein lipase (LPL), and two fatty acid transporters (SLC27A2, and SLC27A4).

[Interinstitutional Command Mexico: organizational decision-making in the face of COVID-19].

Rev Med Inst Mex Seguro Soc

December 2022

Instituto Mexicano del Seguro Social, Centro Médico Nacional Siglo XXI, Unidad de Investigación Epidemiológica y en Servicios de Salud, Área Envejecimiento. Ciudad de México, México.

Background: The third wave of COVID-19 in Mexico produced a high demand for hospital care, which is why it was created a multidisciplinary group to optimize decision-making: the Interinstitutional Command for the Health Sector (COISS, according to its initials in Spanish).

Vascular endothelial growth factor (VEGF) exerts neuroprotective or proinflammatory effects, depending on what VEGF forms (A-E), receptor types (VEGFR1-3), and intracellular signaling pathways are involved. Neonatal monosodium glutamate (MSG) treatment triggers neuronal death by excitotoxicity, which is commonly involved in different neurological disorders, including neurodegenerative diseases. This study was designed to evaluate the effects of VEGFR-2 inhibition on neuronal damage triggered by excitotoxicity in the cerebral motor cortex (CMC) and hippocampus (Hp) after neonatal MSG treatment.

Instituto Politécnico Nacional, Sección de Estudios de Posgrado e Investigación, Escuela Superior de Medicina, Plan de San Luis y Salvador Díaz Mirón S/N, Col. Casco de Santo Tomás, Miguel Hidalgo, Mexico City CP 11340, Mexico.

Ethanolic extract obtained from Miller (EEAc) and the flavonoid rutin (Rut) were evaluated in this study to determine their antihyperglycemic content, % HbA1c reduction, and antihyperlipidemic activities. Both treatments were evaluated separately and in combination with the oral antidiabetic drugs (OADs) acarbose (Aca), metformin (Met), glibenclamide (Gli), and canagliflozin (Cana) in acute and subchronic assays. The evaluation of the acute assay showed that EEAc and Rut administered separately significantly reduce hyperglycemia in a manner similar to OADs and help to reduce % HbA1c and hyperlipidemia in the subchronic assay.

This classical review, along with two revisions published in 2011 and 2022, has remain a classic of the oncology literature. Since many of the addressed biological processes may apply to non-malignant tumorigenesis, we evaluated to what extent these hallmarks pertain to the development of pituitary adenomas.

Background: Genetic variants within nearly 1000 loci are known to contribute to modulation of blood lipid levels. However, the biological pathways underlying these associations are frequently unknown, limiting understanding of these findings and hindering downstream translational efforts such as drug target discovery.

Results: To expand our understanding of the underlying biological pathways and mechanisms controlling blood lipid levels, we leverage a large multi-ancestry meta-analysis (N = 1,654,960) of blood lipids to prioritize putative causal genes for 2286 lipid associations using six gene prediction approaches.
