Relaying on the Oncomine database, we found that LPAR6, compared to normal tissues, was highly expressed in the tumor tissue of brain and CNS, kidney, gastric cancer, leukemia, lymphoma, liver and pancreatic cancer while some data sets showed that LPAR6 has a lower mRNA expression level in bladder, breast, cervical, colorectal, esophageal, lung and prostate cancer (Figure 1A). Here, LPAR6 is linked to prostate carcinoma.
