human ... SFRP1(6422)
一般描述
The gene SFRP1 (secreted frizzled related protein 1) is mapped to human chromosome 8p22–p12, a region frequently deleted in breast cancer. It is highly expressed in normal breast tissue.
免疫原
synthetic peptide corresponding to a sequence at the N-terminal region of human SFRP1.
生化/生理作用
Secreted Frizzled-related protein 1 (SFRP1) is a secreted inhibitor of Wnt signaling pathway. DNA damage or oxidative stress causes cellular senescence, which leads to the overexpression of sfrp1. This protein induces senescence phenotypes via the inactivation of Wnt signaling and activation of the retinoblastoma (Rb) pathway. Mutations or aberrant methylation in this gene impair the induction of senescence in several cancers, including breast cancer, bladder cancer, and colorectal tumorigenesis.

Regions of the short arm of chromosome 8 are deleted frequently in a range of solid tumors, indicating that tumor suppressor genes reside at these loci. In this study, we have examined the properties of the Wnt signaling antagonist secreted

Cellular senescence has emerged as a critical tumor suppressive mechanism in recent years, but relatively little is known about how senescence occurs. Here, we report that secreted Frizzled-related protein 1 (SFRP1), a secreted antagonist of Wnt signaling, is oversecreted upon
