The herbal medicine Melissa officinalis extract effects on gene expression of p53, Bcl-2, Her2, VEGF-A and hTERT in human lung, breast and prostate cancer cell lines

Altogether, it is suggested that the potent antiproliferative activity of the hydroalcoholic extract of Melissa officinalis is somehow explainable by its high potency to inhibit expression of the prominent oncogenes Bcl2, Her2, VEGF-A and hTERT in prostate cancer. In tumors with functional p53, including MCF-7 and A549 cancer cells, the role of p53, Bcl2 and Her2 is less significant. It appears that MOE exerts its antiproliferative effects in these cancer cells partly via concurrent downregulation of VEGF-A and hTERT. Additional studies are needed to clarify the role of other active molecules in cancer cells harboring functional p53.
