lncRNA-p21

lncRNA-p21 is a type of long non-coding RNA, a molecule that does not produce proteins but helps regulate gene activity. It plays a key role in controlling cell responses to stress, such as DNA damage, by influencing which genes are turned on or off. Specifically, lncRNA-p21 can promote cell death (apoptosis), helping prevent the development of tumors. It interacts with other molecules to ensure cells respond appropriately to damage, maintaining proper cellular health and preventing disease. Its function highlights the complex ways our cells use non-coding RNAs to regulate vital biological processes.
