MicroRNA 4521

MicroRNA 4521 (miR-4521) is a small non-coding RNA molecule that regulates gene expression. It is part of the larger family of microRNAs, which play a crucial role in many biological processes, including cell differentiation, proliferation, and apoptosis.

Function[edit | edit source]

miR-4521 is involved in the regulation of gene expression by binding to the 3' untranslated regions (3' UTRs) of target mRNAs. This binding can lead to mRNA degradation or inhibition of translation, thereby reducing the expression of the target gene. The specific genes targeted by miR-4521 are not fully understood, but it is known to be involved in several cellular processes, including cell cycle regulation, apoptosis, and immune response.

Role in Disease[edit | edit source]

miR-4521 has been implicated in several diseases, particularly cancer. Abnormal expression of miR-4521 has been observed in various types of cancer, including breast cancer, lung cancer, and colorectal cancer. In these cancers, miR-4521 often acts as a tumor suppressor, meaning that decreased expression of miR-4521 can contribute to cancer development and progression.

In addition to cancer, miR-4521 has also been associated with other diseases. For example, it has been implicated in neurodegenerative diseases, such as Alzheimer's disease, where it may play a role in the regulation of neuronal function and survival.

Research[edit | edit source]

Research into miR-4521 is ongoing, with scientists seeking to better understand its functions and potential roles in disease. This research could lead to the development of new diagnostic tools or treatments for diseases in which miR-4521 is implicated.
