CD24 and cancer: In the same line, determination of CSNK1G2 effect on CD44/CD24 mRNA expression, which are known cancer stem cell markers, showed that CSNK1G2 silencing in MCF-7 cells significantly accelerated TAM-mediated decrease in the ratio of CD44/CD24 mRNA expression to a greater extent than in NC siRNA-transfected cells (Fig 3G).
