Further, in primary melanoma tumor samples (from http://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE98349 dataset), P4HA2 was expressed at a lower level than P4HA1, and its mRNA expression was not significantly associated with survival (as analyzed by us), in concert with our data. This evidence concerns the gene P4HA2 and neoplasm.
