Figure 1

Recognition of MKRN1 by serum antibodies in patients with esophageal SCC. Escherichia coli containing MKRN1 cDNA expression plasmid (MKRN1) or control empty plasmid (Control) was treated with (+) or without (-) IPTG for 2.5 h, and cell lysates were subsequently subjected to Western blot analysis using the sera from healthy donor #1 and esophageal SCC patients #15 as indicated. An arrow indicates the IPTG-induced polypeptide that represents the encoded MKRN1 cDNA product.
