Transcriptomic signature: Myc haploinsufficient mouse liver (Myc(+/-))

Source: R/Myc_reduce_mice_liver_24m.R
Myc_reduce_mice_liver_24m.Rd

This dataset contains a transcriptomic signature derived from liver tissue of Myc haploinsufficient (Myc(+/-)) mice compared to wild-type (WT) controls. The data represent differential gene expression results obtained using an array-based transcriptomic platform.

Usage
