Chromatin regulator HELLS mediates SSB repair and responses to DNA alkylation damage.

The SNF2 family chromatin remodeler HELLS has emerged as an important regulator of cell proliferation, genome stability, and several cancer pathways. Significant upregulation of HELLS has been reported in 33 human cancer types. While HELLS has been implicated in DNA damage response, its function in DNA repair is poorly understood.

Young men who have sex with men and digital technologies for HIV prevention and care: qualitative findings from the conectad@s study.

Young men who have sex with men in Brazil face vulnerability to HIV and display lower PrEP uptake and adherence. Understanding their engagement with digital technologies can better inform mobile health (mHealth) strategies for HIV prevention and care. As part of the Conectad@s study, a HIV status-neutral prevention and care intervention for young men who have sex with men, we conducted semi-structured interviews and focus group discussions with 38 participants between January-February 2021.

Modulation of diabetes-related retinal pathophysiology by PTX3.

Diabetic retinopathy (DR) is a common complication of diabetes characterized by vascular pathology and neuroinflammation. Pentraxin 3 (PTX3) is a soluble pattern recognition molecule that functions at the crossroads between innate immunity, inflammation, and tissue remodeling. DR is known to involve inflammatory pathways, although the potential relevance of PTX3 has not been explored.

Cholangiocyte ciliary defects induce sustained epidermal growth factor receptor signaling.

Background And Aims: The primary cilium, an organelle that protrudes from cell surfaces, is essential for sensing extracellular signals. With disturbed cellular communication and chronic liver pathologies, this organelle's dysfunctions have been linked to disorders, including polycystic liver disease and cholangiocarcinoma. The goal of this study was to elucidate the relationship between primary cilia and the crucial regulator of cellular proliferation, the epidermal growth factor receptor (EGFR) signaling pathway, which has been associated with various clinical conditions.
