The transcribed pseudogene RPSAP52 enhances the oncofetal HMGA2-IGF2BP2-RAS axis through LIN28B-dependent and independent let-7 inhibition

RPSAP52 is an antisense-transcribed pseudogene of HMGA2 that positively regulates HMGA2 expression. Here, the authors show that reexpression of RPSAP52 promotes tumorigenicity by facilitating IGF2BP2 binding to its mRNA targets and consequently regulates the balance of LIN28B and let-7 levels.
