Idiopathic pulmonary fibrosis is a fatal disease characterized by the TGF-β-dependent activation of lung fibroblasts, leading to excessive deposition of collagen proteins and progressive replacement of healthy lung with scar tissue. We and others have shown that TGF-β-mediated activation of the Mechanistic Target of Rapamycin Complex 1 (mTORC1) and downstream upregulation of Activating Transcription Factor 4 (ATF4) promote metabolic reprogramming in lung fibroblasts characterized by upregulation of the de synthesis of glycine, the most abundant amino acid found in collagen protein. Whether mTOR and ATF4 regulate other metabolic pathways in lung fibroblasts has not been explored.

Although with current treatment, acute mortality from MI is low, the damage and remodeling associated with MI are responsible for subsequent heart failure. Reducing cell death associated with acute MI would decrease the mortality associated with heart failure.

This study investigates the role of Fundc1 in cardiac protection under high-altitude hypoxic conditions and elucidates its underlying molecular mechanisms. Using cardiomyocyte-specific knockout ( ) mice, we demonstrated that deficiency exacerbates cardiac dysfunction under simulated high-altitude hypoxia, manifesting as impaired systolic and diastolic function. Mechanistically, we identified that Fundc1 regulates cardiac function through the mitochondrial unfolded protein response (mito-UPR) pathway.

BACKGROUND The incidence of drug-induced infectious endocarditis is rapidly rising in the United States. Healthcare providers face different challenges in the management of infectious endocarditis in persons who inject drugs, including addiction relapse, non-compliance with treatment, and the associated social stigma. These factors collectively complicate the management of drug-induced endocarditis, requiring comprehensive strategies that address both the medical condition and the underlying substance use disorder, as well as socio-behavioral aspects of patient care.
