Decrease in expression of mRNAs for ALDH1, LGR5, NANOG and OCT4 suggest reduction in populations of ALDH1, LGR5, NANOG and OCT4 positive cancer stem cells by VJ, suggesting that VJ not only decreases the ALDH1 positive cancer stem cells population but other cancer stem cells population also, translating that VJ not only targets ovarian cancer cells, but also different populations of CSC, suggesting that VJ may reduce/eliminate drug-resistance and hence recurrence of ovarian cancer. The gene discussed is LGR5; the disease is ovarian carcinoma.
