YY1 and non-small cell lung carcinoma: In this study, we received specimen from the University Minnesota VA Hospital (UM) to study the survival of LOH for hDMP1, ARF/INK4a, p53; the impacts for overexpression of cyclin D1 and YY1 have also been studied on NSCLC survival, both progression-free survival (PFS) and total survival (TS).
