Periostin activates multiple signaling pathways, including TGF-β, PI3K/Akt, Wnt, NF-κB, MAPK, and JAK, to promote the occurrence and development of various diseases, especially cancer and inflammation.
Matricellular proteins are responsible for regulating the microenvironment, the behaviors of surrounding cells, and the homeostasis of tissues. Periostin (POSTN), a non-structural matricellular protein, can bind to many extracellular matrix proteins through its different domains. POSTN usually presents at low levels in most adult tissues but is highly expressed in pathological sites such as in tumors and inflamed organs. POSTN can bind to diverse integrins to interact with multiple signaling pathways within cells, which is one of its core biological functions. Increasing evidence shows that POSTN can activate the TGF-β, the PI3K/Akt, the Wnt, the RhoA/ROCK, the NF-κB, the MAPK and the JAK pathways to promote the occurrence and development of many diseases, especially cancer and inflammatory diseases. Furthermore, POSTN can interact with some pathways in an upstream and downstream relationship, forming complicated crosstalk. This article focuses on the interactions between POSTN and different signaling pathways in diverse diseases, attempting to explain the mechanisms of interaction and provide novel guidelines for the development of targeted therapies.
Wang et al. (Tue,) conducted a review in Cancer and inflammatory diseases. Periostin (POSTN) was evaluated. Periostin activates multiple signaling pathways, including TGF-β, PI3K/Akt, Wnt, NF-κB, MAPK, and JAK, to promote the occurrence and development of various diseases, especially cancer and inflammation.
