Secreted rotein acidicand rich in cysteine and cancer research / 国际肿瘤学杂志

ABSTRACT

Secreted rotein acidicand rich in cysteine (SPARC), belonging to a family of matricellular proteins, is a multifunctional calcium-binding glycoprotein. In tumors, it functions as de-adhesion, antiproliferation, and regulation of extracellular matrix (ECM) interactions. But in different tumors,SPARC performances different biological effects, as in melanoma, breast cancer, esophageal cancer, etc, SPARC is associated with a highly aggressive tumor phenotype, while in ovarian cancer, cervical cancer, non-small cell lung cancer,SPARC may function as a tumor suppressor.
