a) Levels of STRA6 mRNA in samples of normal human breast and invasive breast carcinoma (36). Data were obtained from Oncomine™ (Compedia Bioscience, Ann Arbor, Michigan). *p<0.05. b) STRA6 expression in a TissueScan™ tissue qPCR array consisting of cDNA derived from samples of normal breast and denoted stages of breast tumors (OriGene). *p<0.05. c) Relative STRA6 mRNA levels in denoted cell lines and in normal human mammary epithelial cells (HuMEC) measured by Q-PCR. #p<0.05 vs. HuMEC. d) Levels of STRA6 mRNA in samples of normal human colon and colon carcinoma (36). *p<0.05 vs. normal colon. e) Analysis of TissueScan™ tissue qPCR array consisting of cDNA derived from samples of normal colon and denoted stages of colon tumors (OriGene). *p<0.05 vs. normal colon. f) Levels of STRA6 mRNA in normal colon tissue and in colon polyps in 60 day old APCmin mice, measured by Q-PCR. Mean±S.E.M. (n=3), ‡p<0.0001 vs. normal mouse colon. g) Relative STRA6 mRNA levels in denoted human colon carcinoma cell lines and in normal human colon cells (normal), measured by Q-PCR. Data are mean±S.E.M (n=3). #p<0.05 vs. normal epithelium cells. h) Relative RBP mRNA levels in denoted cell lines and in normal human mammary epithelial cells (HuMEC) measured by Q-PCR.*p<0.05 vs. HuMEC. i) Levels of STRA6 mRNA in samples of normal human colon cells and colon carcinoma (36)). *p<0.05 vs. normal colon. j) RBP expression in a TissueScan™ tissue qPCR array consisting of cDNA derived from samples of normal colon and denoted stages of colon tumors (OriGene).*p<0.05 vs. normal colon. k) Relative RBP mRNA levels in denoted colon carcinoma cell lines and in normal human colon cells (normal), measured by Q-PCR. Data are mean±S.E.M (n=3). #p<0.05 vs. normal epithelium cells. All data are mean±S.E.M. (n=3).
