M12-28: MRX34 Biomarker study in animals bearing HuH7 orthotopic liver tumors [Affymetrix]

To identify direct tumor mRNA targets of miR-34a, tumor RNAs isolated from whole tumors from animals treated with negative control and MRX34 HuH7 cells were surgically implanted into the livers of Nod/Scid mice and allow to grow for multiple weeks. Once serum AFP levels reached levels consistent with tumor growth of ~80-100 mg, animals were subjected to a single IV injection of MRX34. Twenty-four hours later animals were sacrificed, tumors resected and RNA isolated for subsequent microarray analysis.
