Scientific titleIs the tumour suppressor adenomatous polyposis coli (APC) crucial to iron mediated colorectal carcinogenesis? A single centre observational clinical laboratory study
Study objectivesHypothesis and proof of concept:
Our hypothesis is that increase in cellular iron import proteins (TfR1, DMT1) occur early in the adenoma-carcinoma sequence through mutations in APC and lead to cellular iron loading. As demonstrated in our previous work the effects of this iron loading is to mediate increased Wnt signalling resulting in c-myc induction. This in turn serves to increase the expression of iron import proteins (TfR1, DMT1) and decrease the expression of iron export (ferroportin [FPN]) and storage (ferritin) proteins. Such a hypothesis explains how Wnt signalling controls iron metabolism and ensures that there is adequate cellular iron for ATP generation and cellular proliferation.

Experimental design:
To test such a hypothesis we aim to prospectively collect the following colorectal tissue from patients attending for colonoscopy:
1. Normal colonic mucosa in patients with no colorectal pathology (n = 30)
2. Polyps and matched normal colon (n = 30)
3. Colorectal cancers and matched normal colon (n = 30)

We also intend to collect serum and urine from the following patient groups:
4. Normal colonoscopy (n = 30)
5. Colorectal adenomas (n = 30)
6. Colorectal cancers (n = 30)
Ethics approval(s)Black Country Research Ethics Committee, 03/08/2010, ref: 10/H1202/40
Health condition(s) or problem(s) studiedTopic: National Cancer Research Network; Subtopic: Colorectal Cancer; Disease: Colon
InterventionThis will include the collection of tissue from normal colonic tissue, adenomatous polyps and colorectal cancers. Alongside this we will collect serum and urine to measure systemic iron transport proteins. Following collection of tissue we will determine the expression of APC and the cellular iron transport proteins utilising techniques including, mass spectrometry, western blotting, Real-Time PCR and immunohistochemistry. In each group of patients (normal, polyps or colorectal cancer) we will determine the expression of the iron transport proteins and determine if there are significant changes demonstrable.

Follow Up Length: 12 month(s); Study Entry : Registration only
Intervention typeOther
Primary outcome measureMeasured at baseline, using the expression of proteins in the tissue and serum to detect the cellular and systemic iron transport proteins. The techniques used will include mass spectrometry, western blotting, real time PCR and immunohistochemistry.
Secondary outcome measuresNo secondary outcome measures
