Abnormal Proliferation

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the daughter...

The MN1-BEND2 fusion is a key molecular marker in astroblastoma, a rare brain tumor.

Extracranial occurrences of the MN1-BEND2 fusion are exceptionally rare, with only one prior report in soft-tissue sarcoma.

Soft-tissue sarcomas represent a heterogeneous group of malignancies requiring precise molecular classification.
