Plant polyphenols are nutraceutical components with relevant biological effects on human health. They act against development of several diseases including cancer. In this study, the methanolic extracts of four date palm Phoenix dactylifera leaves (Deglet Noor (DN), Barhee (B), Khalas (KS) and Khunezi (KZ)) collected from south Tunisia were preliminary analyzed for their effects against U87 (human glioblastoma) and MDA-MB-231 (human breast cancer) cell line development. Results showed that Barhee extract (30 μg/mL) was the most efficient to reduce the growth of both tumor cells to about 40% (p < 0.05) without inducing cytotoxicity. Significantly, KS, KZ, DN and B extracts (30 μg/mL) decreased MDA-MB-231 and U87 cell adhesion towards fibrinogen and fibronectin. Using integrin blocking antibodies, leaf extracts competitively decreased human glioblastoma cell attachment to immobilized antibodies by interfering to αvβ3 and α5β1 integrin receptors. At the same concentration, extracts decreased MDA-MB-23 and U87 cell migration performed with wound healing assay. Particularly, Barhee and Deglet Noor leaf extracts (30 μg/mL) significantly reduced U87 cell invasion by 52.92% (p < 0.01) and 74.56% (p < 0.01), respectively. Collegially, our findings revealed beneficial proprieties of four varieties of date palm leaf especially those displayed by DN and B extracts that may serve as active candidates against human glioblastoma and breast cancer progression.
