Transcription profiling by array of human HhAntag-treated pancreatic xenograft tumors

ABSTRACT: Four vehicle-treated and four HhAntag-treated pancreatic xenograft tumors were profiled for gene expression changes using Affymetrix U133 Plus 2.0 and Affymetrix Mouse Genome 430 2.0 arrays. Keywords: comparative gene expression, hedgehog, hh A primary human pancreatic tumor xenograft (1051178-A) was established by direct implantation of surgical material into female CD1 nu/nu mice of 6-8 weeks of age. Tumors were serially passaged into larger cohorts of mice for efficacy testing and subsequently distributed into tumor volume-matched cohorts upon tumors reaching between 200 to 350 mm3. HhAntag was resuspended in 0.5% methyl-cellulose, 0.2% Tween-80 (MCT) and administered orally twice daily at 75 mg/kg from a 10 mg/ml suspension. MCT alone served as vehicle control.
