HMGA2 and ovarian neoplasm: This seems to be the case also for ovarian tumors where the pathway leading to HMGA2 deregulation is relying on overexpression of LIN28A, downregulating let-7a and leading to overexpression of HMGA2. We found that LIN28A showed an average normalized expression of 2 in almost all groups, while let-7a showed a normalized expression close to zero.
