Sox17 and Erg synergistically activate endothelial cell fate in reprogramming fibroblasts.

Sox17-Erg direct reprogramming is a potent tool for the in vitro and in vivo generation of arterial-like induced-endothelial cells from fibroblasts. In this study, we illustrate the pioneering roles of both Sox17 and Erg in the endothelial cell reprogramming process and demonstrate that emergent gene expression only occurs when both factors are co-expressed. Bioinformatic analyses and molecular validation reveal both Bach2 and Etv4 as integral mediators of Sox17-Erg reprogramming with different roles in lung and heart fibroblast reprogramming.

Targeting Endogenous Tau in Seeded Tauopathy Models Inhibits Tau Spread.

The transmission of tau pathology has been proposed as one of the major mechanisms for the spatiotemporal spreading of tau pathology in neurodegenerative diseases. Over the last decade, studies have demonstrated that targeting total or pathological tau using tau antibodies can mitigate the development of tau pathology in tauopathy or Alzheimer's disease (AD) mouse models, and multiple tau immunotherapy agents have progressed to clinical trials. Tau antibodies are believed to inhibit the internalization of pathologic seeds and/or block seed elongation after seed internalization.

Pre-implementation planning to enhance integration of HIV and behavioral health care services at two Ryan White-funded HIV care centers.

Behavioral health conditions are disproportionately experienced by people living with Human immunodeficiency virus (HIV), including young Black gay, bisexual, and other men who have sex with men (GBMSM). Left unaddressed, these symptoms can adversely impact HIV care outcomes. Improving the integration of behavioral health and HIV care services has been proposed as a strategy to address this challenge.

Multi-omic analysis reveals VEGFR2, PI3K, and JNK mediate the small molecule induction of human iPSC-derived cardiomyocyte proliferation.

Mammalian hearts lose their regenerative potential shortly after birth. Stimulating the proliferation of preexisting cardiomyocytes is a potential therapeutic strategy for cardiac damage. In a previous study, we identified 30 compounds that induced the bona-fide proliferation of human iPSC-derived cardiomyocytes (hiPSC-CM).

Successful treatment of forelimb osteochondroma in a ferret (Mustela putorius furo).

A 1-year-old male neutered ferret (Mustela putorius furo) was evaluated for an abnormal left cubital joint. Radiographs demonstrated a proliferative osseous lesion of the left proximal antebrachium. Computed tomography confirmed a large thin-walled expansile osseous lesion of the left proximal radius and identified multifocal proliferative lesions of the axial spine, two of which caused spinal cord compression.
