Williams et al, (13) found upregulation of P-cadherin
expression in severe dysplasia and reduced expression of the E-cadherin and/or catenins in carcinoma in situ and infiltrating tumors.
is a protein that is over-expressed in many common types of cancer, including lung, pancreatic and colon cancers, and is implicated in tumor growth and cancer disease progression.
FF-21101 uses antibodies that target P-cadherin
, which is over-expressed on the surface of solid cancer cells, and accumulated in lung cancer cells, pancreatic cancer cells, etc.
Other MEC markers, such as SMA, p-cadherin
, Wilms tumor 1 (WT1), S100, and high-molecular-weight cytokeratin (HMWCK) or basal-type cytokeratin (CK) (CK5/6, CK14, CK17, CK903) are less commonly used because of marked cross-reactivity with myofibroblasts and vascular SMA, (4-9,19,20) frequent reactivity in tumor cells (HMWCK or basal-type CK, S100, p-cadherin
), (4-8,19,32-34) or low sensitivity (WT1 and S100).
The expression of P-cadherin
is restricted only to basal or lower layers of epithelia, including prostate and skin and also to breast myoepithelial cells (MECs).
Cell adhesion molecules P-cadherin
and CD24 are markers for carcinoma and dysplasia in the biliary tract.
and alpha 6 beta 4 intergrin is altered in pre-malignant skin tumors of p53-deficient mice.
Expression and role E-and P-cadherin
adhesion molecules in embryonic histogenesis.
We demonstrated that while bi-layered organization in mammary epithelium is driven mainly by the lineage-specific differential expression of the E-cadherin adhesion protein, the expression of the P-cadherin
adhesion protein makes additional contributions that are specific to the organization of the myoepithelial layer," LaBarge says.
