Researchers in Hong Kong, People's Republic of China, have uncovered the chemoprotective mechanism by which lycopene prevents polycyclic aromatic hydrocarbons (PAH)-induced carcinogenesis in the breast. Lycopene, a carotenoid widely distributed in fruit and vegetables, has been shown to inhibit phase 1 enzymes and induce phase 2 enzymes,

Tumor cells in a state of hypoxia, characterized by a lack of oxygen, release soluble factors like vascular endothelial growth factor (VEGF) that induce angiogenesis - the formation of new blood vessels - to enhance tumor growth and facilitate metastasis. Researchers in Seoul, Korea, have discovered that thymosin beta-4 (TB4)

Scientists in Hsinchu, Taiwan, have investigated the role of securin and gamma-H2AX in baicalein-induced cancer cell death. Baicalein, a natural flavonoid, reduced cell viability in various human cancer cell lines, including bladder, cervical, colon, and lung cancer cells. The study found that baicalein treatment significantly inhibited securin expression while elevating
