The results showed that NSUN2 mRNA expression levels were upregulated in the invasive breast cancer tissues, compared with the normal tissues (Figure 1A), and this is especially true for invasive lobularl breast carcinomas, compared with ductal breast carcinomas (Figure 1B and 1D), as well as invasive ductal breast carcinoma vs ductal breast carcinoma in situ (Figure 1C). This evidence concerns the gene NSUN2 and ductal breast carcinoma in situ.
