Number of steps taken matters more for better health in older women than the frequency

A large prospective study found that achieving at least 4000 steps per day on 1-2 days per week is associated with a significantly lower risk of death and lower risk of cardiovascular disease. This study suggests that frequency of meeting daily step thresholds is not critical, but rather the volume of steps taken.

Lactate–acetate interaction between tumor-associated macrophages and cancer cells drives hepatocellular carcinoma metastasis

Researchers found that tumor-associated macrophages produce acetate through a metabolic interaction involving lactate and the lipid peroxidation–ALDH2 pathway. This acetate promotes histone H3 acetylation and epithelial-mesenchymal transition in hepatocellular carcinoma cells, enhancing metastasis.
