We examined the associations between physical activity (PA)-measured through self-reported walking and vigorous activities-and pain occurrence (self-reported bothersome pain or frequent pain medication use), and persistent pain (pain occurring for two consecutive years). This analysis used a large, nationally representative sample of 2279 older adults from the National Health and Aging Trends Study of 2015-2018, and applied generalized estimating equation regression with propensity score weighting. Approximately 70% and 50% of the participants reported walking and vigorous activities respectively at baseline.

E3 ligase substrate adaptor SPOP fine-tunes the UPR of pancreatic β cells.

Genes Dev

December 2024

Institute for Diabetes, Obesity, and Metabolism, Department of Medicine, Perelman School of Medicine, University of Pennsylvania, Philadelphia, Pennsylvania 19146, USA;

The Cullin-3 E3 ligase adaptor protein SPOP targets proteins for ubiquitination and proteasomal degradation. We previously established the β-cell transcription factor (TF) and human diabetes gene PDX1 as an SPOP substrate, suggesting a functional role for SPOP in the β cell. Here, we generated a β-cell-specific deletion mouse strain ( ) and found that is necessary to prevent aberrant basal insulin secretion and for maintaining glucose-stimulated insulin secretion through impacts on glycolysis and glucose-stimulated calcium flux.

Synthetic rational design of live-attenuated Zika viruses based on a computational model.

Nucleic Acids Res

January 2025

SynVaccine Ltd, Ramat Hachayal, 3 Golda Meir Street, Science Park, Nes Ziona 7403648, Israel.

Many viruses of the Flaviviridae family, including the Zika virus (ZIKV), are human pathogens of significant public health concerns. Despite extensive research, there are currently no approved vaccines available for ZIKV and specifically no live-attenuated Zika vaccine. In this current study, we suggest a novel computational algorithm for generating live-attenuated vaccines via the introduction of silent mutation into regions that undergo selection for strong or weak local RNA folding or into regions that exhibit medium levels of sequence conservation.
