Identification of novel non-synonymous variants associated with type 2 diabetes-related metabolites in Korean population.

Identification of novel non-synonymous variants associated with type 2 diabetes-related metabolites in Korean population. Biosci Rep. 2019 Oct 30;39(10): Authors: Park TJ, Lee HS, Kim YJ, Kim BJ Abstract Metabolome-genome wide association studies (mGWASs) are useful for understanding the genetic regulation of metabolites in complex diseases, including type 2 diabetes (T2D). Numerous genetic variants associated with T2D-related metabolites have been identified in previous mGWASs; however, these analyses seem to have difficulty in detecting the genetic variants with functional effects. An exome array focussed on potentially functional variants is an alternative platform to obtain insight into the genetics of biochemical conversion processes. In the present study, we performed an mGWAS using 27,140 non-synonymous variants included in the Illumina HumanExome BeadChip and nine T2D-related metabolites identified by a targetted metabolomics approach to evaluate 2,338 Korean individuals from the Korea Association REsource (KARE) cohort. A linear regression analysis controlling for age, sex, BMI, and T2D status as covariates was performed to identify novel non-synonymous variants associated with T2D-related metabolites. We found significant associations between glycine and CPS1 (rs1047883) and PC ae C36:0 and CYP4F2 (rs2108622) variants (P

Studies reveal that people living with type 1 diabetes are at three and a half times the risk, and people living with type 2 are at double the risk of dying in hospital with the virus, compared to people without diabetes. A new helpline is part of a package of measures already in place for people with diabetes or at risk.

This study was the first to demonstrate a causal relationship between glial senescence and neurodegeneration. In this study, accumulations of senescent astrocytes and microglia were found in tau-associated neurodegenerative disease model mice. Elimination of these senescent cells via a genetic approach can reduce tau deposition and prevent the degeneration of cortical and hippocampal neurons. Most recently, it was shown that clearance of senescent oligodendrocyte progenitor cells in AD model mice with senolytic agents could lessen the Aβ plaque load, reduce neuroinflammation, and ameliorate cognitive deficits. ...

(Science China Press) This research aimed at investigating the hypoglycemic mechanism for CP. It was found that CP markedly attenuated the symptoms of diabetes, and inhibited the protein expression of Bax, improved the expression of Bcl-2 in pancreas of diabetic rats, normalized hormones secretion and controlled the inflammation which contributed to the regeneration of pancreaticβ-cell and insulin resistance.

CONCLUSIONS: Low serum magnesium levels have a greater association with an increased risk of mortality compared to high levels. The type of dialysis fluid affects the magnesium concentration and the risk of death. PMID: 32651086 [PubMed - as supplied by publisher]

AbstractPurpose of ReviewThe highly infectious transmissible disease, the novel SARS-CoV-2, causing the coronavirus disease (COVID-19), has a median incubation time of 5 to 15  days. The symptoms vary from person to person and many are “hidden carriers.” Few people experience immediate reaction and even death within 48 h of infection. However, many show mild to chronic symptoms and recover. Nevertheless, the death rate due to COVID-19 transmission is high especially among patients with non-communicable diseases. The purpose of this review is to provide evidence to consider vitamins as epigenetic modif...
