Hyperaminoacidemia from interrupted glucagon signaling increases pancreatic acinar cell proliferation and size via mTORC1 and YAP pathways.

Increased blood amino acid levels (hyperaminoacidemia) stimulate pancreas expansion by unclear mechanisms. Here, by genetic and pharmacological disruption of glucagon receptor (GCGR) in mice and zebrafish, we found that the ensuing hyperaminoacidemia promotes pancreatic acinar cell proliferation and cell hypertrophy, which can be mitigated by a low protein diet in mice. In addition to mammalian target of rapamycin complex 1 (mTORC1) signaling, acinar cell proliferation required , the most highly expressed amino acid transporter gene in both species.

Routine review of patient-reported outcome data influences radiotherapy care: IMPROVE study results.

Background: Radiation oncologists closely monitor patients during weekly on-treatment visits (OTVs). This study examines whether routine patient-reported outcome measures (PROMs) during OTVs change physicians' perceptions of treatment-toxicity and inform symptom-management.

Patient And Methods: IMPROVE is a single-arm prospective multicenter trial, conducted from 2020 to 2023.

Horst Oertel and the Russell Sage Institute of Pathology: Impacts on vital statistics and the origins of the short-lived heyday of autopsies in America.

Horst Oertel was an early 20th century pathologist who began his career as an instructor of clinical pathology at the New York University and Bellevue Hospital Medical College in 1899. In 1903, he was appointed pathologist for City Hospital, an institution for indigent patients on New York City's Blackwell's Island. In 1907, Oertel became the first director of the Russell Sage Institute of Pathology, a unique new blended public-private entity based at City Hospital, that was named after a wealthy benefactor.

Chromosome-scale genome assembly and de novo annotation of Alopecurus aequalis.

Alopecurus aequalis is a winter annual or short-lived perennial bunchgrass which has in recent years emerged as the dominant agricultural weed of barley and wheat in certain regions of China and Japan, causing significant yield losses. Its robust tillering capacity and high fecundity, combined with the development of both target and non-target-site resistance to herbicides means it is a formidable challenge to food security. Here we report on a chromosome-scale assembly of A.
