Next Generation Sequencing Quantitative Analysis of the transcriptomes of Wild Type and Mki67-/- 4T1 tumors in mice
Purpose: The goals of this study were to compare gene expression profiles of mouse xenografted 4T1 tumors with intact or disrupted Mki67 gene. Methods: mRNA profiles of wild-type (WT) and Ki-67 knockout (Mki67-/-) mouse xenografted 4T1 tumors, in triplicate, were generated by deep sequencing using Illumina Hiseq2500 in paired-end read mode, 50bp. The sequence reads that passed quality filters were aligned to the mouse genome, quantified, and differential gene expression (DGE) analysis was performed using DEseq2. Results: Using an optimized data analysis workflow, we mapped about 30 million sequence reads per sample to the mouse genome (GRCm38.p6) and identified differentially expressed genes.  This revealed widespread changes in gene expression Conclusions: Ki-67 knockout causes genome-scale transcriptome alterations Overall design: mRNA profiles of wild-type (WT) and Ki-67 knockout (Mki67-/-) mouse xenografted 4T1 tumors, in triplicate, were generated by deep sequencing using Illumina Hiseq2500 in paired-end read mode, 50bp.
