Dysfunctional cells are eliminated from epithelial monolayers by a process known as cell extrusion to maintain tissue homeostasis. Normal epithelial cells are now shown to induce the extrusion of oncogene-transformed cells by inducing metabolic changes in the oncogene-expressing cells through PDK4-mediated inhibition of PDH and mitochondrial metabolism.

Understanding metabolic conditions related to glycolysis dependence is crucial for developing new treatments in cancer and regenerative medicine. This protocol details a method for using the live-cell metabolic analyzer (LiCellMo) to measure continuous changes in glucose consumption and lactate production in cultured human cells. LiCellMo provides real-time data on consecutive metabolic changes, improving measurements of these processes in various contexts, including in cancer and regenerative treatments.

Sterols target sterol-sensing domain (SSD) proteins to lower cholesterol and circulating and hepatic triglyceride levels, but the mechanism remains unclear. In this study, we identify acyl-coenzyme A (CoA) synthetase long-chain family member 1 (ACSL1) as a direct target of ergosterol (ES). The C-terminal domain of ACSL1 undergoes conformational changes from closed to open, and ES may target the drug-binding pocket in the acetyl-CoA synthetase-like domain 1 (ASLD1) of ACSL1 to stabilize the closed conformation and maintain its activity.

Neurodegenerative diseases are significant health concerns that have a profound impact on the quality and duration of life for millions of individuals. These diseases are characterized by pathological changes in various brain regions, specific genetic mutations associated with the disease, deposits of abnormal proteins, and the degeneration of neurological cells. As neurodegenerative disorders vary in their epidemiological characteristics and vulnerability of neurons, treatment of these diseases is usually aimed at slowing disease progression.

The kinetically-derived maximal dose (KMD) is defined as the maximum external dose at which kinetics are unchanged relative to lower doses, e.g., doses at which kinetic processes are not saturated.
