PTGDR and colorectal carcinoma: These transcripts belong to the GCG (glucagon), NMES-1 (normal mucosa of esophagus-specific 1, also called C15orf48), LRMP (lymphoid-restricted membrane protein), FAM161B (family with sequence similarity 161, member B), and PTGDR (prostaglandin D2 receptor) genes, which also showed differential expression in our previous pilot study [35], but have not been linked to CRC before, and to CDKN2B, a known tumor suppressor gene.
