oil emulsion improves the effect of radiotherapy on esophageal cancer cells by inhibiting cyclin D1-CDK4/6 axis.

Background: Esophageal cancer is one of the most common cancers around the world, and it has high incidence and mortality rates. The conventional therapy for esophageal cancer is radiotherapy, although its effect is highly limited by the resistance of esophageal cancer cells. Thus, strong radiosensitizers can be very crucial during radiotherapy against esophageal cancer.

Investigations on in vitro anti-carcinogenic potential of L-carnosine in liver cancer cells.

This study was carried out to investigate the anti-carcinogenic effect of L-carnosine in human carcinoma cells (SNU-423). The SNU-423 cancer cells were cultured at a density of 2 × 10 cells/well in Dulbecco modified Eagle medium. After 24 h of adherence, the cells were treated with L-carnosine (0.
