Results of p90RSK gene silencing in cancer cell lines and various Raf/Ras/ERK pathway activation in human breast cancer. p90RSK inhibition was done in MCF7 and ZR-75-1 cells by using siRNA against p90RSK. Student t-test showed no significant difference in cell proliferation in cells treated with siRNA against p90RSK and cells treated with scramble siRNA (a). The expression levels of total and phosphorylated various Raf/Ras/ERK pathway molecules were measured in primary breast cancer tissues from 20 breast cancer patients.
