Abstract
- Breast cancer is the second most cancer worldwide in females. The primary factor responsible for tumor recurrence is the presence of breast cancer stem cells (BCSCs), which escape the chemo-radiotherapy. In this study, we have investigated the role of Secretory phospholipase-A2 Group 2A (sPLA 2 -IIA) that is overexpressed in BCSCs of MCF7 and MDA-MB-231 breast cancer cell lines. Further, overexpression of sPLA 2 -IIA revealed an increased EGFR/JNK/c-JUN/c-FOS signaling in BCSCs, while sPLA 2 -IIA knockdown significantly reduced the percentage of BCSCs and decreased signaling in both the cell lines. Importantly, sPLA 2 -IIA knockdown showed differentiation of BCSCs. Strikingly, PET imaging showed a decreased metastatic potential of BCSCs. Our study revealed a novel role of sPLA 2 -IIA in regulating BCSCs, which play a crucial role in regulating the differentiation and metastatic potential of BCSCs. [Display omitted] • SPLA2-IIA knockdown reduces the number of BCSCs. • Loss of sPLA2-IIA decreases the tumorigenic potential of BCSCs in NOD/SCID mice. • SPLA2-IIA knockdown enhances the differentiation potential of BCSCs. • SPLA2-IIA knockdown leads to a decrease in the metastatic potential of BCSCs. • SPLA2-IIA knockdown reduces the EGFR/JNK/c-JUN-c-FOS signaling in BCSCs.
