For example, in the process of cell cycle, METTL3 can enhance the translation of FOXD2-AS1 (lncRNA FOXD2 adjacent opposite strand RNA 1) mRNA, recruit the key transcription silencing factor LSD1 (lysine-specific demethylase 1) to the promoter of p21 to silence the transcription of cell cycle inhibitor p21, thus promoting the proliferation and migration of cervical cancer and inhibiting the apoptosis of cancer cells (20); In addition, CDC25B (cell division cyclin 25B) is an important factor affecting the activation of cyclin-dependent kinases (21). The gene discussed is CDC25B; the disease is cervical cancer.
