The goal of the present work was to evaluate the correlation of glucose transporter 1 (GLUT1) and carbonic anhydrase IX (CAIX) with the monocarboxylate transporters 1 (MCT1) and 4 (MCT4) and their chaperone, CD147, in breast cancer.
Targeting proteins involved in vesicular transport like Rab GTPases, the neural precursor cell-expressed developmentally downregulated protein 9 (NEDD9), runt-related transcription factor 2 (RUNX2), human rhomboid family-1 (RHBDF1), monocarboxylate transporter 4, etc., would aid in designing improved therapeutics for the treatment of breast cancer.
These results suggest that MCT4 is a potential therapeutic target in defined breast cancer subtypes and reveal novel avenues for combination treatment.
High expression of MCT1 and MCT4 in tumour tissues was associated with poor patient outcome; further the correlation between MCT1 expression and poor prognosis in breast cancer was further strengthened when combined with MCT4 overexpression in the adjacent adipose tissue.
