COMPARITIVE STUDY OF DENDRITIC CELL VACCINE PREPARATION WITH PRESENCE AND ABSENCE OF MALPIGHIA EMARGINATA FRUIT EXTRACT USING TUMOR RNA TRANSFECTION METHOD: A PROMISING APPROACH FOR PROSTATE CANCER

Abstract

Acerola (Malpighia emarginata DC) is the richest natural source of ascorbic acid and also contains a plethora of phytonutrients such as flavonoids, anthocyanins, carotenoids, and phenolics. By using the fruits of Malpighia emarginata, are used for the treatment of cancer by inducing effective anti-tumor immunity through dendritic cells. Dendritic cells (DC) are the heterogeneous population of antigen-presenting cells that invade tumors. They play an important role in the priming and maintenance of local immunity, and their major function is diminished by some factors encountered in the local environment. For the success of cancer immunotherapy, adequate tumor-specific antigens play a very important role in inducing a tumor-specific immune response by effective delivery of these antigens. In this proposal, by using these strategies, mature and immature dendritic cells were obtained in-vitro by adding specific cytokines to monocyte cell culture containing Malpighia emarginata fruit extract in the presence of prostate-specific antigen (PSA), and their results were compared to those obtained without the presence of Malpighia emarginata fruit extract. In the prostate tumor lineage, the RNA is extracted into the cell by electroporation, and the transfection success was measured by immunocytochemistry of the PSA expression level in dendritic cells. For the comparative study of in-vitro RNA transcription, this method allows small tumors to be used for dendritic cell vaccine preparation through the activation of DC by in the presence and absence of Malpighia emarginata fruit extract and it is a promising approach for the treatment of metastatic prostate cancer.
