MicroRNA expression profiling of livers from the conditional doxycyline-regulatable c-Myc-driven liver tumor mouse model during tumor development and regression.

Progressing and regressing liver tumor tissues (depending on the group) were subjected to miRNA profiling to identify the miRNA changes occuring during tumor development and regression. Conditional doxycyline-regulatable c-Myc-driven mice get liver tumors following doxycycline (Dox) withdrawal from their diet. When mice are re-administered Dox through their diet, tumors start to regress. Overall design: In this study, the developing tumor group (ULST) and the regressing tumor group 'treated' (re-administrered through food) with doxycycline (TLST), each group had four mice per group, ie., biological replicates (1-4).
