“ EGCG alone did not cause DNA damage in colorectal cancer cells, but its combination with irinotecan could induce S or G2 phase arrest by inhibiting topoisomerase I to cause more extensive DNA damage.”
“ EGCG also induced apoptosis by promoting autophagy with irinotecan synergistically.”
“The results showed that EGCG combined with irinotecan (0.5 μmol L−) not only had a stronger inhibitory effect on tumour cells than EGCG or irinotecan alone but also prevented tumour cell migration and invasion.”
