Detection of guanylyl cyclase C mRNA in lymph nodes of resected stage II colorectal cancer is highly correlated with the risk of tumor recurrence. If validated, these results could have significant implications for the selection of patients for adjuvant therapy in this disease.

Cyclic nucleotide-gated (CNG) channels are a family of ion channels activated by the binding of cyclic nucleotides. Endogenous channels have been used to measure cyclic nucleotide signals in photoreceptor outer segments and olfactory cilia for decades. Here we have investigated the subcellular localization of cGMP signals by monitoring CNG channel activity in response to agonists that activate ...

Introduction: Following a proximal small bowel resection (SBR), the intestine adapts by increased crypt depth and villus height compared to sham operated mice (transection and reanastomosis only). The epidermal growth factor receptor (EGFR) is a known mediator of intestinal adaptation and results in activation of the GTPase Rac. This activates PAK (p21-activated protein kinase) which may activa...

Colorectal cancer (CRC) is a major cause of cancer-related mortality and morbidity worldwide. While improved treatments have enhanced overall patient outcome, disease burden encompassing quality of life, cost of care, and patient survival has seen little benefit. Consequently, additional advances in CRC treatments remain important, with an emphasis on preventative measures. Guanylyl cyclase C (...
