A study has shown that silencing RNA targeting PARK7 significantly increased the PTEN expression, which resulted in an increase in cell death and decreased cell proliferation and invasion in the laryngeal cancer cells (32), and increase of PARK7 triggers the surviving expression, resulting in the inhibition of apoptosis and cell proliferation of laryngeal carcinoma cells (15). This evidence concerns the gene PARK7 and laryngeal carcinoma.
