By contrast, by analyzing seven independent human colorectal cancer tissue gene expression-patient prognosis datasets, RNA sequencing human breast cancer tissue gene expression-patient prognosis TCGA datasets and an Oncomine data-mining platform, Kwok et al. and Kim et al. have very recently found that MALAT1 gene expression is decreased in human colorectal and breast cancer tissues, and that a low level of MALAT1 is associated with decreased patient survival. This evidence concerns the gene MALAT1 and breast cancer.
