Comparison of the effects of crizotinib as monotherapy and as combination therapy with butyric acid on different breast cancer cells.

In recent years, there have been significant developments using combined therapies in cancer treatment. The present study aimed to determine the effects of using crizotinib alone and in combination with butyric acid on different types of breast cancer cells. A total of three different breast cancer models were used: MDA-MB-231, a triple negative model; MCF-7, a Luminal A model; and SKBR-3 cell line, a human epidermal growth factor receptor 2 positive model.

Effects of combined use of ribociclib with PARP1 inhibitor on cell kinetics in breast cancer.

In the present study, antiproliferative and anticancer effects of Valamor (VLM), which contains the active component ribociclib, and DPQ, a poly(ADP-ribose) polymerase 1 inhibitor, alone and in combination were evaluated in the MCF-7 and MDA-MB-231 breast cancer cell lines . VLM was applied at concentrations of 40, 80 and 160 µg/ml, and DPQ was used at concentrations of 3, 6 and 9 µg/ml. The proliferation rate, cell index obtained from the real-time cell analysis system, mitosis activity, bromodeoxyuridine cell proliferation and caspase activity parameters were determined.
