Consistent expression of guanylyl cyclase-C in primary and metastatic gastrointestinal cancers

BACKGROUND The transmembrane receptor guanylate cyclase-C (GCC) has been found to be expressed in colorectal cancers. However, limited data are available on GCC protein expression in non-colorectal gastrointestinal tumors and few studies have reported whether GCC protein expression was consistently preserved in synchronous primary and metastatic cancer tissues. METHODS GCC protein status was ...

Comparison of c-Kit expression between primary and metastatic melanoma of skin and mucosa

  Background: Melanoma causes the greatest morbidity and mortality of all skin cancers. Mucosal melanoma is a rare but highly aggressive neoplasm. According to previous studies the prevalence of KIT mutations in acrallentiginous and mucosal melanomas is relatively low (less than 15–20%), but it can have profound therapeutic implications for localized high risk or metastatic diseases. Our goal w...

Glycosylation of human receptor guanylyl cyclase C

Background Post translational modifications regulate several signalling pathways and glycosylation is emerging as a key player in this regulatory process. Glycosylation of cell surface receptors modulate the downstream signalling pathway and when altered causes a change in the normal physiology of the cell [1]. Guanylyl cyclase C (GC-C) belongs to a group of membrane bound receptors that produc...

Ectopic expression of guanylyl cyclase C in adenocarcinomas of the esophagus and stomach.

Guanylyl cyclase C (GC-C), a receptor specifically expressed in cells originating from differentiated intestinal epithelium, is a marker and therapeutic target for colorectal cancer metastases. Intestinal metaplasia, in which epithelial cells assume histological and molecular characteristics of differentiated intestinal enterocytes, is a common precursor to adenocarcinomas of the esophagus and ...

Expression of the intestinal biomarkers Guanylyl cyclase C and CDX2 in poorly differentiated colorectal carcinomas.

Guanylyl cyclase C, a receptor for bacterial diarrheagenic enterotoxins, is expressed selectively by intestinal epithelium and is an endogenous downstream target of CDX2. The expression of Guanylyl cyclase C is preserved throughout the adenoma/carcinoma sequence in the colorectum. Detection of Guanylyl cyclase C expression by reverse transcriptase-polymerase chain reaction is currently being va...
