KRAS and colorectal carcinoma: To make full use of all the nine samples with transcriptome sequencing for further bioinformatics analysis, we performed DEGs analysis on four CRC samples with both KRAS phenotype and transcriptome sequencing data to obtain KRAS mutation-related DEGs and utilized the CC approach to predict the KRAS mutation status in another five CRC patients on the basis of the KRAS mutation-related DEGs expression matrix of these nine samples.
