PEBP1 and cancer: We observed that the molecules found altered in RKIP KO cells belong to several enriched pathways (KEEG pathways), which are not fully concordant among genes and proteins: at the mRNA level there is an enrichment in cancer and MAPK associated pathways (Fig. 4A), while considering the MS results, the proteins found were associated with spliceosomes and microRNAs in cancer, being the last one also found among the enriched pathways at mRNA level (Fig. 4B).
