Antibody blockade of the Cripto CFC domain suppresses tumor cell growth in vivo.
Cripto, a cell surface-associated protein belonging to the EGF-CFC family of growth factor-like molecules, is overexpressed in many human solid tumors, including 70-80% of breast and colon tumors, yet how it promotes cell transformation is unclear. During embryogenesis, Cripto complexes with Alk4 via its unique cysteine-rich CFC domain to facilitate signaling by the TGF-beta ligand Nodal. We re...
متن کاملStructure-function analysis of the EGF-CFC family member Cripto identifies residues essential for nodal signalling.
Cripto is the founding member of the family of EGF-CFC genes, a class of extracellular factors essential for early vertebrate development. In this study we show that injection of Cripto recombinant protein in mid to late zebrafish Maternal-Zygotic one-eyed pinhead (MZoep) blastulae was able to fully rescue the mutant phenotype, thus providing the first direct evidence that Cripto activity can b...
متن کاملBiological and Clinicopathological Significance of Cripto-1 Expression in the Progression of Human ESCC
Background: Human Cripto-1, a member of the EGF-CFC family, is involved in embryonic development, embryonic stem cell maintenance, and tumor progression. It also participates in multiple cell signaling pathways including Wnt, Notch, and TGF-β. Remarkably, it is expressed in cancer stem cell (CSC) compartments, boosting tumor cell migration, invasion, and angiogenesis. Although Cripto-1 is ...
متن کاملAutoregulation and Heterogeneity in Expression of Human Cripto-1
Cripto-1 (CR-1) is involved in various processes in embryonic development and cancer. Multiple pathways regulate CR-1 expression. Our present work demonstrates a possible positive feedback circuit where CR-1 induces its own expression. Using U-87 MG cells treated with exogenous CR-1, we show that such induction involves ALK4/SMAD2/3 pathway. Stochasticity in gene expression gives rise to hetero...
متن کاملThe wall of the chick embryo aorta harbours M-CFC, G-CFC, GM-CFC and BFU-E.
In the 3- to 4-day avian embryo, after the first wave of haemopoiesis which derives in the yolk sac from haemopoietic stem cells formed in situ, haemopoietic cells emerge in an intraembryonic site, the wall of the aorta. In this paper, we demonstrate that this site harbours M-CFC, G-CFC, GM-CFC and late and early BFU-E. In serum-free medium, the growth of M-CFC and GM-CFC was strictly dependent...
