RB1 and cervical cancer: The therapeutic potential of siRNA in cervical cancer treatments stems from its ability to selectively bind and degrade complementary mRNA sequences, resulting in the inhibition of oncoprotein synthesis.62 In cervical cancer treatment, siRNA silences E6 and E7 oncogenes, which further restores p53 tumor suppression protein and pRb protein, thus leading to arrest of the cell cycle, cell death, and proliferation of tumor cells.63
