An "In Schizo" Evaluation System to Screen for Human Kinesin-5 Inhibitors.

Kinesin-5 motor proteins are essential for mitotic spindle formation and maintenance, ensuring accurate chromosome segregation. Human kinesin-5 is highly expressed in various cancer cells but not in nonproliferative tissues; therefore, it is expected to be an attractive target for cancer chemotherapy, with fewer adverse side effects. Many inhibitors have been developed and subjected to clinical trials; however, they have not yet been commercially distributed because of their poor efficacy and frequent drug resistance.

D-aspartate stimulates growth hormone secretion in wethers.

Growth hormone (GH) is an essential factor in enhancing the productivity of animals. In ruminants, L-aspartate (L-Asp) stimulates the secretion of GH; however, the effect of D-Asp on GH remains unknown. Here, we examined the effect of D-Asp on GH secretion in wethers.

Exploratory functional and quality of life outcomes with daily consumption of the ketone ester bis-octanoyl (R)-1,3-butanediol in healthy older adults: a randomized, parallel arm, double-blind, placebo-controlled study.

Background: Ketone bodies are metabolites produced during fasting or on a ketogenic diet that have pleiotropic effects on the inflammatory and metabolic aging pathways underpinning frailty in models. Ketone esters (KEs) are compounds that induce hyperketonemia without dietary changes and that may impact physical and cognitive function in young adults. The functional effects of KEs have not been studied in older adults.

Daily consumption of ketone ester, bis-octanoyl (R)-1,3-butanediol, is safe and tolerable in healthy older adults in a randomized, parallel arm, double-blind, placebo-controlled, pilot study.

Objectives: Ketone bodies are endogenous metabolites produced during fasting or a ketogenic diet that have pleiotropic effects on aging pathways. Ketone esters (KEs) are compounds that induce ketosis without dietary changes, but KEs have not been studied in an older adult population. The primary objective of this trial was to assess the tolerability and safety of KE ingestion in a cohort of older adults.
