The estrogen-sensitive MCF-7 breast cancer cell line was used for these studies.

It also inhibited the growth of the breast cancer cell line MCF-7.

The growth inhibition rate of MCF-7 was increased in a concentration-and time-dependent manner.

We aimed to study gene expression profiling circumstances in MCF-7 during MDR development.

However, no significant growth inhibition was found between untreated control and RA-treated MCF-10A cells.
