Similarly, LOXL2 is found to promote colorectal cancer [19], gastric cancer [20,21], esophageal squamous cell carcinoma [22], cholangiocarcinoma [23], hepatocellular carcinoma [24], lung squamous cell carcinoma [25], non-small cell lung cancer [26,27], and renal cell carcinoma [28], to name some examples out of the many types of cancer in which tumor progression is enhanced by LOXL2. Here, LOXL2 is linked to esophageal squamous cell carcinoma.
