Differential gene expression in GBS6 cells after EWS-POU5F1 knockdown


ABSTRACT: Our objective is to clarify the function of EWS-POU5F1 chimera. Specifially, GBS6 cells were established from an undifferentiated bone sarcoma carrying translocation t(6;22)(p21;q12). The translocation resulted in a gene fusion between EWS and POU5F1. Gene expression analysis of t(6;22) undifferentiated sarcoma cell line GBS6 transfected with POU5F1 specific siRNA to investigate the function of EWS-POU5F1. Knockdown of EWS-POU5F1 using POU5F1 specific siRNAs. 3 control and 6 experimental replicates representing the same experiment repeated 3 times (1st, 2nd, 3rd).

POU5F1 is a transcription factor essential for the self-renewal activity and pluripotency of embryonic stem cells and germ cells. We have previously reported that POU5F1 is fused to EWSR1 in a case of undifferentiated sarcoma with chromosomal translocation t(6;22)(p21;q12). In addition, the EWS-POU5F1 chimeras have been recently identified in human neoplasms of the skin and salivary glands. To clarify the roles of the EWS-POU5F1 chimera in tumorigenesis and tumor cell maintenance, we used small-  ...[more]
