Beyond immunostaining for cellular survivin protein expression in primary liposarcoma subtypes, the expression of survivin was quantified in three LPS cell lines by qPCR on mRNA levels as well as by western blotting on protein levels: while the DDLPS cell line Lipo-DUE1 was characterized by high RNA-levels of survivin and low protein-levels—presumably due to post translational modifications—the two other cell lines Lipo246A (DDLPS) and PLS-1 (PLS) exhibiting only low to moderate survivin RNA levels impressed with substantially higher amounts of survivin protein expression. The gene discussed is BIRC5; the disease is liposarcoma.
