CCND1 and cervical squamous cell carcinoma: One study proved that the expression of miR-424-5p was decreased in cervical squamous cell carcinoma and may target many cell cycle regulatory factors (CCND1, CCNE1, WEE1), indicating that miR-424-5p plays a biological role in cervical squamous cell carcinoma by regulating cell cycle factors and inhibiting cell proliferation and metastasis.
