Production of lactate is one of the main features of tumours, promoting acidification of tumour microenvironment and consequently increases tumoral growth. In this way, several studies of our group have reported the inhibition of lactate transporters (MCTs) which promotes the inhibition of lactate transport to cell outside, inducing cell death. Thus, in this study MCT1 and MCT4 gene was silenced in human breast cancer cells, which induced a decrease in cell proliferation, migration and invasion.
