Additionally, 3,4-dihydrozybenzoic acid was also reported to cause apoptosis on human breast cancer MCF-7 cell, lung cancer A-549 cell, HepG2 cell, cervix HeLa cell, prostate cancer LNCaP cell, and A549 human lung cancer [ 21 , 22 , 23 ]. Moreover, methyl ferulate previously showed antiproliferative effect on colorectal cancer cells, MCF-7, PC-3, HL-60, MCF-7, and A-549 cells [ 24 , 25 , 26 ].…”
