Therapeutic regimens for inhibiting breast cancer with aberrant Akt activity are critical. Here, we evaluated antitumor impact of a marine bacteria derived lipopeptide `Iturin A' on human breast cancer in vitro and in vivo via disrupting Akt pathway. Proliferation of MDAMB231 and MCF7 breast cancer cells were significantly inhibited by Iturin A and it induced apoptosis as confirmed by improved Sub G1 populations, DNA fragmentation, morphological alterations and western blot analysis. Moreover, Iturin A inhibited EGF induced Akt phosphorylation (Ser473 and Thr308) and its downstream targets GSK3 and FoxO3a. Iturin A inactivated MAPK as well as Akt kinase major towards the translocation of FoxO3a for the nucleus. Gene silencing of Akt in MDAMB231 and MCF7 cells decreased the sensitivity of cancer cells to Iturin A. Interestingly, overexpression of Akt with Akt plasmid in cancer cells triggered extremely susceptible to induce apoptosis by Iturin A therapy. Within a xenograft model, Iturin A inhibited tumor growth with decreased expressions of Ki67, CD31, PAkt, PGSK3 , PFoxO3a and PMAPK. Collectively, these findings imply that Iturin A has possible anticancer impact on breast cancer.The menace of chemoresistance on the cancer cells and also a steady decline within the discovery of new lead anticancer molecules has thrown a formidable research challenge towards the concerned scientific community. One of one of the most prevalent cancers is breast cancer that is certainly a popular malignancy affecting females worldwide. It can be created as a consequence of a number of cellular and molecular transformations that bring about breast cancer cell proliferation and inhibition of apoptosis. These events involve disrupting several signaling networks and thereby resulting in altered gene expression. Among these deregulated signaling pathways, Akt/PKB plays as main contributor to the development of several cancers like breast cancer1,2.
