HLA-DPB1 E69 genotype and exposure in beryllium sensitisation and disease.

Occup Environ Med 2021 Sep 17. Epub 2021 Sep 17.

Department of Medicine, National Jewish Health, Denver, Colorado, USA

Objectives: Human leukocyte antigen-DP beta 1 (HLA-DPB1) with a glutamic acid at the 69th position of the ß chain (E69) genotype and inhalational beryllium exposure individually contribute to risk of chronic beryllium disease (CBD) and beryllium sensitisation (BeS) in exposed individuals. This retrospective nested case-control study assessed the contribution of genetics and exposure in the development of BeS and CBD.

Methods: Workers with BeS (n=444), CBD (n=449) and beryllium-exposed controls (n=890) were enrolled from studies conducted at nuclear weapons and primary beryllium manufacturing facilities. Read More

Hidden historical habitat-linked population divergence and contemporary gene flow of a deep-sea patellogastropod limpet.

Mol Biol Evol 2021 Sep 17. Epub 2021 Sep 17.

Southern Marine Science and Engineering Guangdong Laboratory (Guangzhou), Guangzhou, China.

Hydrothermal vents and hydrocarbon seeps in the deep ocean are rare oases fuelled by chemosynthesis. Biological communities inhabiting these ecosystems are often distributed in widely separated habitats, raising intriguing questions on how these organisms achieve connectivity and whether habitat types facilitate intraspecific divergence. The deep-sea patellogastropod limpet Bathyacmaea nipponica that colonises both vents and seeps across ∼2,400 km in the Northwest Pacific is a feasible model to answer these questions. Read More

The "GG" genotype of rs26802 variant in the ghrelin gene is a potential protective factor against nonalcoholic fatty liver disease.

Physiol Int 2021 Sep 16. Epub 2021 Sep 16.

2 Gastroenterology and Liver Diseases Research Center, Research Institute for Gastroenterology and Liver Diseases, Shahid Beheshti University of Medical Sciences, Tehran, Iran.

Background: Nonalcoholic fatty liver disease (NAFLD) is an emerging global chronic liver disease worldwide. Considering the powerful association between NAFLD, insulin resistance (IR) and obesity, as well as the key role of ghrelin in these metabolic disorders, we hypothesized that some single nucleotide polymorphisms (SNPs) of the ghrelin (GHRL) and ghrelin receptor (GHSR) genes might be associated with NAFLD.
