FOS and cancer: To verify that FOS is truly regulated by OCT4A in somatic cancer cells, we compared the FOS mRNA level between WT and OCT4A-KO clones (2-2, 1-1 and A2), between U87/Huh7-NC and U87/Huh7-KO (other somatic cancer cell models with CRISPR-Cas9-mediated non-targeting control (NC) and OCT4A-knockout (KO) in the whole cell population), respectively.
