Next, we assessed the effect of METTL3 knockdown on PCAT6 stability and found a significantly decreased half‐life of PCAT6 in PCa cells treated with METTL3 siRNA (Figure 7G), indicating that METTL3 regulated PCAT6 expression by modulating PCAT6 stability. The gene discussed is PCAT6; the disease is posterior cortical atrophy.
