How could a scientist use siRNA to turn off a cancer inducing gene.?

A scientist could use small interfering RNA (siRNA) to target and degrade the messenger RNA (mRNA) of a cancer-inducing gene. By designing siRNA that is complementary to the specific mRNA sequence of the gene, the siRNA can bind to the mRNA and promote its degradation through the RNA-induced silencing complex (RISC). This effectively reduces or eliminates the expression of the cancerous protein, thereby potentially inhibiting tumor growth and progression. Additionally, delivering the siRNA into cancer cells can be achieved through various methods, such as lipid nanoparticles or viral vectors, to enhance its effectiveness.
