Hypothesis
The study aims to determine the levels of cAMP binding proteins in human colorectal cancers and related mucosa and to correlate these levels to known prognostic factors.
Conclusion
Cyclic AMP binding proteins are over-expressed in human colorectal cancers and their levels are related to the stage and grade of the cancer.
Supporting Evidence
- Cyclic AMP binding was significantly higher in tumors than in adjacent or distant mucosa.
- Binding levels in adjacent mucosa were lower than in distant mucosa.
- Binding was higher in Dukes' B than Dukes' C cancers.
Takeaway
This study found that cancer cells in the colon have more cAMP binding proteins than normal cells nearby, which might help doctors understand how advanced the cancer is.
Methodology
The study measured cAMP binding protein levels in the cytosols of colorectal cancer specimens and related mucosa using a competitive binding assay.
Limitations
The study does not address the long-term prognostic implications of cAMP binding protein levels.
