Additionally, MDM2-ALT3 was detected in liposarcoma tumor samples by Okoro and colleagues in 2013 [14], and while the expression of MDM2-ALT2 correlated with the MDM2 overexpression in SJSA and MANCA cell lines, this correlation was not tested in liposarcoma or breast cancer patient samples used in the study [14]. This evidence concerns the gene MDM2 and liposarcoma.
