Conversely, an nCounter analysis of the mRNA expression levels of all TAS2Rs in the metastatic breast cancer cell line (MDA-MB-231) and normal breast cell line (MCF-10A) revealed a higher relative expression of the two predominantly expressed TAS2Rs, namely TAS2R14 and TAS2R20, in the cancer cell line, whereas no differences were detected for other TAS2Rs [25]. This evidence concerns the gene TAS2R20 and breast carcinoma.
