Background: Placenta-specific 1 (PLAC1) is one of the cancer-testis-placenta antigens that has no expression in normal tissue except placenta trophoblast and testicular germ cells, but is overexpressed in a variety of solid tumors. There is a lack of studies on the expression of PLAC1 in leukemia. We investigated expression of in Acute Myeloid Leukemia (AML) and Acute Lymphoblastic Leukemia (ALL).
Methods: In this study, we investigated expression pattern of gene in peripheral blood and bone marrow mononuclear cells of newly-diagnosed patients with AML (n=31) and ALL (n=31) using quantitative real-time PCR. Normal subjects (n=17) were considered as control. The PLAC1 protein expression in the samples were also detected using western blotting.
Results: Our data demonstrated that transcripts had 2.7 and 2.9 fold-change increase in AML and ALL, respectively, compared to normal samples. transcript expression was totally negative in all studied normal subjects. Level of mRNA expression in ALL statistically increased compared to normal samples (p=0.038). However, relative mRNA expression of in AML was not significant in comparison to normal subjects (p=0.848). Furthermore, relative mRNA expression of in AML subtypes was not statistically significant (p=0.756). gene expression showed no difference in demographical clinical and para-clinical parameters. Western blotting confirmed expression of PLAC1 in the ALL and AML samples.
Conclusion: Considering expression profile in acute leukemia, PLAC1 could be a potential marker in leukemia which needs complementary studies in the future.
