Genetic risk converges on regulatory networks mediating early type 2 diabetes
Integration of multiomics data with functional analysis of pancreatic tissues from individuals with early-stage type 2 diabetes indicates that the genetic risk converges on RFX6, which regulates chromatin architecture at multiple risk loci.

Feedback modulation of cholesterol metabolism by the lipid-responsive non-coding RNA LeXis
The activation of lipid X receptors (LXRs) in mouse liver not only promotes cholesterol efflux but also inhibits cholesterol synthesis simultaneously; this is mediated by the lipid-responsive long non-coding RNA LeXis, which is induced by a Western diet and orchestrates crosstalk between LXRs and the cholesterol biosynthetic pathway.

Depletion of fat-resident Treg cells prevents age-associated insulin resistance
Fat-resident regulatory T cells (fTreg cells) accumulate in adipose tissue of mice as a function of age, but not obesity; mice without fTreg cells are protected against age-associated insulin resistance, but remain susceptible to obesity-associated insulin resistance and metabolic disease, indicating different aetiologies of age-associated versus obesity-associated insulin resistance.

FXR is a molecular target for the effects of vertical sleeve gastrectomy
Bariatric surgical procedures, such as vertical sleeve gastrectomy (VSG), are the most effective therapy for the treatment of obesity; now bile acids, and the presence of the nuclear bile acid receptor FXR, are shown to underpin the mechanism of VSG action, and the ability of VSG to reduce body weight and improve glucose tolerance is substantially reduced if FXR is absent.

Chronic high-fat diet in fathers programs β-cell dysfunction in female rat offspring
Here it is shown that the consumption of a high-fat diet by male rats has an intergenerational effect: it leads to the dysfunction of pancreatic β-cells in female offspring. Relative to controls, these offspring showed an early onset of impaired insulin secretion and glucose tolerance, which worsened with time. The results add to our understanding of the complex genetic and environmental factors that are leading to the global epidemic of obesity and type 2 diabetes.

Rfx6 directs islet formation and insulin production in mice and humans
Pancreatic β-cells release insulin, which controls energy homeostasis in vertebrates, and its lack causes diabetes mellitus. The transcription factor neurogenin 3 (Neurog3) initiates differentiation of β-cells and other islet cell types from pancreatic endoderm; here, the transcription factor Rfx6 is shown to direct islet cell differentiation downstream of Neurog3 in mice and humans. This may be useful in efforts to generate β-cells for patients with diabetes.

Hsp70 stabilizes lysosomes and reverts Niemann–Pick disease-associated lysosomal pathology
Heat shock protein 70 (Hsp70) is a molecular chaperone which, by inhibiting lysosomal membrane permeabilization, promotes the survival of stressed cells. Hsp70 is now shown to stabilize lysosomes by binding to an anionic phospholipid, BMP, resulting in stimulation of acid sphingomyelinase (ASM) activity. Notably, the decreased ASM activity and lysosomal stability seen in patients with Niemann–Pick disease can be corrected by treatment with recombinant Hsp70.
