mRNA expression of XAGE-1 transcript variants in NSCLC

TumorXAGE-1aXAGE-1b*XAGE-1cXAGE-1d
Adenocarcinoma0/3114/31 (45%)0/316/31 (19%)
Squamous cell carcinoma0/151/15 (7%)0/150/15
Large cell carcinoma0/20/20/20/2
Carcinoid0/10/10/10/1
  • * Because the primer pair, X-1 and X-2, detects XAGE-1a and XAGE-1b cDNA; XAGE-1b mRNA expression was defined by negative expression of XAGE-1a mRNA and nucleotide sequencing.
