ΔNp73, a TP73 gene isoform, is found to participate in the development of cancer in different stages.[80] Soldevilla et al. demonstrate that the levels of ΔNp73 mRNA are higher in CRC‐derived exosomes than their parental cells and that exosomal ΔNp73 mRNA promotes oncogenic potential and chemoresistance in the recipient cells.[81] Zhou et al. show that the mRNA levels of glycerol kinase 5 (GK5) are higher in gefitinib‐resistant (GR) cells than GR‐sensitive ones. Here, GK5 is linked to cancer.
