Background: Mobility is a key social determinant of health for female sex workers (FSWs). While extant research has focused on the adverse effects of mobility for FSWs, there are very few studies that have examined the multiple ways in which mobility may impact the lives of these mobile women from their perspective. This qualitative study aims to fill this gap by exploring how mobility impacts the lives, livelihoods, and HIV care and treatment from the perspectives of women living with HIV in two epidemic settings, the Dominican Republic and Tanzania.

Cryo-EM Structure of AAA + ATPase Thorase Reveals Novel Helical Filament Formation.

bioRxiv

November 2024

Neuroregeneration and Stem Cell Programs, Institute for Cell Engineering, The Johns Hopkins University School of Medicine, Baltimore, Maryland, United States of America.

The AAA+ (ATPases associated with a variety of cellular activities) ATPase, Thorase, also known as ATAD1, plays multiple roles in synaptic plasticity, mitochondrial quality control and mTOR signaling through disassembling protein complexes like AMPAR and mTORC1 in an ATP-dependent manner. The Oligomerization of Thorase is crucial for its disassembly and remodeling functions. We show that wild-type Thorase forms long helical filaments , dependent on ATP binding but not hydrolysis.

Senescence suppresses the integrated stress response and activates a stress-remodeled secretory phenotype.

Mol Cell

November 2024

Laboratory of Genetics and Genomics, National Institute on Aging, Intramural Research Program, National Institutes of Health, Baltimore, MD 21224, USA. Electronic address:

Article Synopsis
  • Senescence is when cells stop dividing, linked to aging and diseases like cancer, and is characterized by a weakened ability to respond to stress.
  • Senescent cells show signs of stress response activation, like high eIF2α phosphorylation, but still fail to produce the stress response factor ATF4 due to ineffective regulatory mechanisms.
  • When stressed, these cells not only struggle to respond effectively but also increase inflammation, which seems to be influenced by the levels of ATF4 mRNA that lack specific regulatory elements.

Article Synopsis
  • About 12% of diarrhoeal cases last 7-13 days, termed prolonged diarrhoea, which is linked to the majority of diarrhoeal deaths in young children.
  • The study evaluated young children (2-23 months) with acute (<7 days) and prolonged (≥7-13 days) diarrhoea using data from a large trial conducted across seven countries in Asia and sub-Saharan Africa between 2017 and 2019.
  • Findings showed that prolonged diarrhoea was associated with factors like younger age, larger family size, maternal illiteracy, moderate underweight, and the presence of certain pathogens, with significant implications for children's health outcomes at a 90-day follow-up.

SET and MYND-domain containing protein 3 (SMYD3) mediates epigenetic repression of type I IFN response genes in human papillomavirus (HPV)-negative HNSCC cells, and Smyd3 depletion using anti-sense oligonucleotides (ASOs) increases the sensitivity of syngeneic mouse oral carcinoma (MOC1) models to anti-PD-1 therapy. In this study, we utilized single-cell RNA-seq of MOC1 tumors treated with Smyd3 ASOs and found enrichment of type I IFN response pathways in cancer cells, a shift of CD8 T-cells toward an activated/memory phenotype, and a shift of neutrophils toward an anti-tumorigenic phenotype. Mechanisms of resistance to the Smyd3 ASO and anti-PD-1 combination were derived from cancer cells, macrophages, and CD8 T-cells, including neutrophil enrichment through the upregulation of , repression of and defective antigen presentation.
