Divergent outcomes of SAK3, a T-type calcium channel enhancer, in two luminal-A type breast cancer cell lines: T-47D and MCF7

Abstract

AbstractVoltage-gated calcium channels have emerged as promising targets in breast cancer. Breast cancer cell lines are widely used as experimental models. In our pursuit to explore the potential of augmenting T-type voltage-gated calcium channels as a therapeutic approach for breast cancer, we made an unexpected discovery: similar breast cancer subtype cell lines exhibited varying responses to SAK3, a T-type voltage-gated calcium channel enhancer, in terms of proliferation and intracellular calcium levels. In presenting these contrasting findings here, we aim to underscore the importance of exercising caution and validating results obtained from cell lines by cross-referencing them with other cell lines or models.
