Scientists found that luteolin (20 μM) + lycopene (10 μM) was the best therapeutic combination in sodium palmitate (PA)-induced HepG2 cells, and significantly improved cell viability and lipid accumulation in PA-induced HepG2 cells and primary hepatocytes.
Researchers explored the relationship between the relevant regulatory factors and the epithelial-mesenchymal transition signaling pathways in the various intrahepatic cells.

The roles of calcium silicate (CS)-activated H9 cells in liver injury repair were tested by cell tracking and immunohistochemical staining. Results indicated that high concentrations of CS extracts initially enhanced definitive endodermal (DE) lineage, followed by gradual DE differentiation at low CS concentrations.

On 24 June, the US National Institutes of Health (NIH) described the actions it will take when alerted to reports of unsafe behavior, including restricting scientists from peer-review panels, holding back pending grants and refusing university requests to transfer funding to other institutions in cases where a harasser changes jobs.
A series of recent studies has demonstrated a significant drop in the productivity of female scientists, especially those early in their careers, relative to their male peers—and the gender gap is particularly pronounced for COVID-19 researchers.
