Several other studies identify promising biomarkers for different types of cancer, such as MALAT1 derived fragment detected in plasma as a biomarker for prostate cancer (Ren et al., 2013), AA174084 found in gastric juice as indicator of gastric cancer (Shao et al., 2014), a set of salivary lncRNAs as potential markers for oral squamous cell carcinoma diagnosis (Tang et al., 2013). This evidence concerns the gene MALAT1 and cancer.
