Loss of functional β-cell mass is an essential feature of type 2 diabetes, and maintaining mature β-cell identity is important for preserving a functional β-cell mass. However, it is unclear how β-cells achieve and maintain their mature identity. Here we demonstrate a novel function of protein arginine methyltransferase 1 (PRMT1) in maintaining mature β-cell identity. Prmt1 knockout in fetal and adult β-cells induced diabetes, which was aggravated by high-fat diet–induced metabolic stress. Deletion of Prmt1 in adult β-cells resulted in the immediate loss of histone H4 arginine 3 asymmetric dimethylation (H4R3me2a) and the subsequent loss of β-cell identity. The expression levels of genes involved in mature β-cell function and identity were robustly downregulated as soon as Prmt1 deletion was induced in adult β-cells. Chromatin immunoprecipitation sequencing and assay for transposase-accessible chromatin sequencing analyses revealed that PRMT1-dependent H4R3me2a increases chromatin accessibility at the binding sites for CCCTC-binding factor (CTCF) and β-cell transcription factors. In addition, PRMT1-dependent open chromatin regions may show an association with the risk of diabetes in humans. Together, our results indicate that PRMT1 plays an essential role in maintaining β-cell identity by regulating chromatin accessibility.

The host environment is a crucial factor for considering the transplant of stem cell–derived immature pancreatic cells in patients with type 1 diabetes. Here, we investigated the effect of insulin (INS)-deficient diabetes on the fate of immature pancreatic endocrine cell grafts and the underlying mechanisms. Human induced pluripotent stem cell–derived pancreatic endocrine progenitor cells (EPCs), which contained a high proportion of chromogranin A⁺ NK6 homeobox 1⁺ cells and very few INS⁺ cells, were used. When the EPCs were implanted under the kidney capsule in immunodeficient mice, INS-deficient diabetes accelerated increase in plasma human C-peptide, a marker of graft-derived INS secretion. The acceleration was suppressed by INS infusion but not affected by partial attenuation of hyperglycemia by dapagliflozin, an INS-independent glucose-lowering agent. Immunohistochemical analyses indicated that the grafts from diabetic mice contained more endocrine cells including proliferative INS-producing cells compared with that from nondiabetic mice, despite no difference in whole graft mass between the two groups. These data suggest that INS-deficient diabetes upregulates the INS-secreting capacity of EPC grafts by increasing the number of endocrine cells including INS-producing cells without changing the graft mass. These findings provide useful insights into postoperative diabetic care for cell therapy using stem cell–derived pancreatic cells.

At some point over the next six weeks, injuries, improvement or regression will inevitably alter the plan nearly every Major League club brings into Spring Training. The Braves must decide exactly how to round out their rotation and bullpen, but for now it looks like they won't have any position-player battles. Here's the first prediction of how Atlanta's Opening Day roster might look.

We're reluctant to finalize our list of offseason winners because, as you may have heard, there are some prominent unsigned free agents. Not just Bryce Harper and Manny Machado, either.

As the Braves open camp, they'll provide a glimpse of how much they have progressed since claiming an unexpected division crown last year. Freddie Freeman, Ronald Acuna Jr. and Ozzie Albies will once again be in a lineup that has been enriched by the addition of Josh Donaldson, the former American League MVP Award winner who thus far arguably ranks as baseball's top free-agent signee.

When the Braves re-signed Nick Markakis in January, they began leaning toward putting Ender Inciarte in the leadoff spot and moving Ronald Acuna Jr. to the cleanup role. But manager Brian Snitker said Acuna may still get his wish to stay at the top of the lineup.

The next five weeks will see lots of shuffling on Major League rosters. Here are the most intriguing positional battles on each of the 30 MLB clubs.

Having seen what Luiz Gohara had done upon his introduction to the big leagues the previous September, Freddie Freeman told Alex Anthopoulos the big left-hander might immediately became an All-Star. Instead, it became a year of awakening for the young hurler, who remains fueled by last year's disappointments.

To those of a certain age, Frank Robinson was the definition of greatness, leadership and toughness. Well into his 70's and 80's, he carried himself with the confidence and unmistakable gait of a great athlete.

As we inch closer and closer to Opening Day, we'll continue to take a position-by-position look at the Orioles roster options and remaining questions. Now that pitchers and catchers have officially reported to Spring Training, now feels like a good time to take a look behind the plate, where the Orioles have a ton of options but no clear answer.

The next five weeks will see lots of shuffling on Major League rosters. Here are the most intriguing positional battles on each of the 30 MLB clubs.

The Orioles began a long-overdue rebuild in July, when the club dealt many of its more-valued big assets in exchange for prospects.

There won't be many roster battles when the Astros open camp later this week, and they won't be decided until the final days of the team's stay in West Palm Beach, Fla. Houston has an open competition for its fifth starter spot heading into Spring Training, and the club also has to sort out a crowded outfield and the final spots in the bullpen.

Abdominal aortic aneurysms (AAA) are usually asymptomatic until they rupture, which is fatal in more than 80% of cases. Screening aims to detect the aneurysm before it ruptures, enabling preventive surgery and hence reducing morbidity and mortality. However, preventive surgery has a mortality of 3.9-4.5%. As the prevalence of risk factors, ie...
