Abstract: CD24 (cluster of differentiation 24) is a small heavy glycosylated protein, which is overexpressed
in many cancer and some cancer stem cells and is associated with the development, invasion,
and metastasis of cancer cells. The exact role of CD24 in these processes is not fully understood,
however, in this article, it has been tried to present a collection of cancer-related mechanisms
attributed to CD24. Based on the literature, CD24 dis-regulates different signaling pathways in various
cancer cells, including; Src kinases, STAT3, EGFR, Wnt/β-catenin and MAPK. Src kinases play
an important role in the signaling pathways which activate p38 MAPK and STAT3 pathways. Akt
and ERK are downstream effectors of CD24-activated EGFR, which promote cell proliferation, invasion
and metastasis. CD24 increases the expression of HER2 by the activation of NF-κB transcription
factor. Moreover, CD24 up-regulates the expression of miR-21 oncomir through the activation
of Src kinases. Identification of the details of these pathways and also new pathways will help researchers
to explore new CD24 targeted therapies.
