[EX Q]: We have previously shown that advanced glycation-endproducts (AGEs) induced NFκB activation in differentiated mouse podocytes. This NFκB activation may contribute to the progression of renal disease and mediation of fibrosis by various mechanisms. This study was undertaken to test whether this detrimental response may be reversed by vitamin D3 or its analogue paricalcitol.', 'Differentiated mouse podocytes were challenged with glycated bovine serum albumin (AGE-BSA), or non-glycated control BSA (in the presence or absence of various concentrations of vitamin D3 (decostriol, 1α,25-dihydroxyvitamin D3)) or its active analog paricalcitol. Quantitative mRNA expressions were measured by real-time PCR, whereas protein expressions were determined by Western blotting followed by densitometry. Cytoplasmic and nuclear protein expression of the NFκB subunit p65 (Rel A) were determined by Western blotting. Furthermore, the ratio of phosphorylated to non-phosphorylated IκB-α was measured using specific antibodies. Electrophoretic mobility shift assays and a capture ELISA assay were used to assess NFκB transactivation in vitro. In addition, NFκB transactivation was also monitored in HEK-NFκBIA reporter cells using live cell luminometry.', 'Podocytes expressed the receptor for vitamin D. The vitamins did not suppress receptor for AGEs (RAGE) expression; instead, they rather upregulated RAGE. Although vitamin D3 and paricalcitol partly and differentially modified some of the studied parameters, both hormones inhibited AGE-BSA-induced NFκB transactivation, presumably by various mechanisms including the upregulation of IκB-α protein, keeping NFκB sequestered in an inactive state in the cytoplasm.

[EX Q]: One variant of multiple endocrine neoplasia type 1 (MEN1) is defined by sporadic tumors of both the parathyroids and pituitary. The prevalence of identified MEN1 mutations in this variant is lower than in familial MEN1 (7% vs. 90%), suggesting different causes. Recently, one case of this variant had a germline mutation of p27(Kip1)/CDKN1B.', 'The objective was to test p27 in germline DNA from cases with tumors of both the parathyroids and pituitary.', 'Medical record review and sequence analysis in DNA were performed.', 'This study involved an inpatient and outpatient referral program for cases of endocrine tumors.', 'Sixteen index cases had sporadic tumors of two organs, both the parathyroids and the pituitary. There were 18 additional index cases with related features of familial tumors. Five subjects were normal controls. No case had an identified MEN1 mutation.', 'Clinical status of endocrine tumors was tabulated. Sequencing of germline DNA from index cases and control cases for the p27 gene was performed by PCR.', 'Endocrine tumor types and their expressions were measured, as were sequence changes in the p27 gene.', 'Tumor features were documented in index cases and families. One p27 germline single nucleotide change was identified. This predicted a silent substitution of Thr142Thr. Furthermore, there was a normal prevalence of heterozygosity for a common p27 polymorphism, making a large p27 deletion unlikely in all or most of these cases.

[EX Q]: Type 2 diabetes mellitus (T2DM) is characterized as a disease continuum that is marked by metabolic changes that are present for several years, sometimes well before frank diagnosis of T2DM. Genetic predisposition, ethnicity, geography, alterations in BMI, and lipid profile are considered important markers for the pathogenesis of T2DM through mechanisms that remain unresolved and controversial. The aim of this study was to investigate the relationship between triglycerides (TGs) and β-cell function, insulin resistance (IR), and insulin sensitivity (IS) in obese first-degree relatives of patients with T2DM (FDR-T2DM) among subjects from central Mexico with normal glucose tolerance (NGT).', 'We studied 372 FDR-T2DM subjects (ages,18-65) and determined body mass index (BMI), fasting plasma glucose (FPG), oral glucose tolerance test (OGTT), insulin, and TGs levels. Subjects were categorized based on glycemic control [NGT, prediabetes (PT2DM), or T2DM]. NGT subjects were further categorized by BMI [normal weight (Ob-) or obese (Ob+)] and TGs levels (TG-, <150\u2009mg/dL, or TG+, ≥150\u2009mg/dL). β-cell function, IR, and IS were determined by the homeostasis model assessment of β-cell function (HOMA2-β), homeostasis model assessment of insulin resistance (HOMA2-IR), and Quantitative Insulin Sensitivity Check Index (QUICKI) indices, respectively.', 'The obese subjects with elevated TGs levels had 21%-60% increased β-cell function when compared to all groups (P<0.05). In addition, this group had insulin levels, IS, and IR similar to PT2DM. Furthermore, only in obese subjects did TGs correlate with β-cell function (ρ=0.502, P<0.001).
