SNAI1 and prostate cancer: MiR-128, which is regulated by snail family zinc finger 1 (SNAIL) transcriptionally, in turn modulates the expression of ribosomal protein S6 kinase, polypeptide 1 (RPS6KB1), also known as p70S6K, and afterwards disrupts downstream HIF-1α at the translational level and consequently suppresses pyruvate kinase 2 (PKM2) expression to inhibit the growth and metabolism of prostate cancer cells [137], which expands the interplay between HIF-1α and miRNA at the translational level.
