CYP24A1 is an independent prognostic marker of survival in patients with lung adenocarcinoma.

ABSTRACT:

Purpose

The active form of vitamin D, 1α,25-dihydroxyvitamin D(3) (1,25-D(3)), exerts antiproliferative effects in cancers, including lung adenocarcinoma (AC). CYP24A1 is overexpressed in many cancers and encodes the enzyme that catabolizes 1,25-D(3). The purpose of our study was to assess CYP24A1 as a prognostic marker and to study its relevance to antiproliferative activity of 1,25-D(3) in lung AC cells.

Experimental design

Tumors and corresponding normal specimens from 86 patients with lung AC (stages I-III) were available. Affymetrix array data and subsequent confirmation by quantitative real time-PCR were used to determine CYP24A1 mRNA expression. A subsequent validation set of 101 lung AC was used to confirm CYP24A1 mRNA expression and its associations with clinical va
