Analysis on the Clinical Research Progress of Menin Inhibitor

Menin is an expression product of the tumorigenic gene MEN1 in multiple endocrine neoplasia. Multiple endocrine neoplasia syndrome is a familial autosomal dominant disease characterized by endocrine organ tumors such as thyroid, pancreatic islets, and anterior pituitary tumors. The occurrence of facial vascular fibroma, glioma, and lipomas are also related to MEN1. 

Studies show that abnormal Menin expression is associated with the occurrence of diseases such as leukemia and diabetes. The mechanism by which mutations promote tumor formation is mainly through the loss of function of the two alleles, causing minor mutations such as missense mutations, or larger mutations such as heterozygous loss. More than 400 types of MEN1 mutations have been found in mammals and microorganisms, most of which are nonsense mutations and frameshift mutations. These two types of mutations lead to shortened gene encoding or inactivation of Menin, thereby changing the key function of Menin in inhibiting tumor activity. In pancreatic islet cells, Menin mutations will lead to excessive proliferation of β cells and result in islet β-cell tumors. Excessive Menin expression levels can obstruct the proliferation process of β cells, leading to relatively insufficient insulin secretion.

Menin is a protein encoded by the MEN1 gene and plays a crucial role in the human body. It acts as a tumor suppressor and is primarily found in the nucleus of cells. Menin is involved in regulating gene expression, cell division, and DNA repair processes. It interacts with various proteins and transcription factors to control cell growth and differentiation. Mutations in the MEN1 gene can lead to the development of multiple endocrine neoplasia type 1 (MEN1) syndrome, a hereditary disorder characterized by the formation of tumors in various endocrine organs. Understanding the role of menin is essential for developing targeted therapies for MEN1 syndrome and other related conditions.
