TNFRSF10A and breast cancer: In accordance with these in silico data, overexpression of miR-519a-3p consistently reduced the expression of TNFRSF10B (TRAIL-R2) but not of TNFRSF10A (TRAIL-R1) or FAS mRNA in the immortalized but nontransformed MCF10A epithelial cell line as well as in several breast cancer cell lines, MDA-MB-231, HCC1143, T47D and MDA-MB-468 (Figure 1a).
