The cancer stem cell theory is considered as the spotlight of cancer biology, in which a subpopulation of tumor cells show unlimited proliferative and self renewal capacities. Post-transcriptional regulation is involved in different cellular functions such as cell differentiation and proliferation which results in cellular diversity. Musashi1 (Msi1) is one of the most important RNA-binding proteins (RBPs) which are involved in translational inhibition. Although, Msi1 targets are largely unknown, p21WAF-1, a cell cycle regulator, and Numb, inhibitor of notch signaling pathway, are well-known factors which are suppressed by the Msi1 in normal and cancer stem cells. Msi1 expression in tumor tissues from 53 ESCC patients was compared to normal tissues using real-time polymerase chain reaction (PCR). Msi1 was significantely overexpressed in 41.5 % of tumor samples and we observed a significant correlation between Msi1 expression and sex, in which the males had shown a higher level of Msi1 expression in comparison with the females (2.00 Vs 0.78 fold changes, p = 0.05). In this study, we assessed whether Msi1 is expressed in ESCC samples suggesting this protein as a novel cancer stem cell marker which requires further studies.
