CD14 and cancer: These proteins are involved in different pathways; however, it was interesting to observe that groups of two proteins were classified by KEGG inside the same pathway, namely, HSPA2 and CD14, both cancer related proteins, inside the MAPK signaling pathway and HSPA2 with RRBP1 inside the protein processing in the endoplasmic reticulum pathway, which could be interesting to further investigate in future studies.
