Next generation sequencing analysis of control and KSR1 knockdown CRC cell line translatomes.


ABSTRACT: KSR1 signaling alters the translational landscape of human CRC cells to support their survival. To determine the effect of KSR1 on translatomes in colon cancer cells, we performed genome-wide polysome profiling. We stably expressed short hairpin RNA (shRNA) constructs targeting KSR1 or a non-targeting control in two K-Ras mutant CRC cell lines, HCT116 and HCT15. We isolated and quantified both total mRNA and efficiently translated mRNAs (associated with ≥ 3 ribosomes) using RNA sequencing. We used Anota2seq to calculate translation efficiency (TE) by comparing the differences in efficiently translated mRNAs to the total transcript of each mRNA.
