Caffeine induces sustained apoptosis of human gastric cancer cells by activating the caspase-9/caspase-3 signalling pathway

Caffeine is one of the most widely consumed substances found in beverages, and has demonstrated anticancer effects in several types of cancer. The present study aimed to examine the anticancer effects of caffeine on gastric cancer (GC) cells (MGC‑803 and SGC‑7901) in vitro, and to determine whether the apoptosis‑related caspase‑9/-3 pathway is associated with these effects. The sustained antiproliferative effects of caffeine on gastric cancer...
