Hypothesis

The expression of RARRES3 protein is correlated with tumor differentiation in colorectal adenocarcinoma.

Conclusion

RARRES3 expression is positively correlated with tumor differentiation in colorectal cancer, but it is not a prognostic marker.

Supporting Evidence

  • RARRES3 protein is expressed at high levels in normal colorectal mucosa and adenoma tissues.
  • Moderately and poorly differentiated colorectal tumors showed a progressive loss of RARRES3 expression.
  • The study found no significant association between RARRES3 expression and Dukes' stages.

Takeaway

RARRES3 is a protein that helps keep cells healthy, and in cancer, its levels can show how well the cancer cells are behaving.

Methodology

The study analyzed RARRES3 protein expression in colorectal tissues using immunohistochemistry.

Limitations

The study did not find RARRES3 to be a prognostic marker for colorectal adenocarcinoma.

Participant Demographics

The study included 120 patients with colorectal adenocarcinoma and 20 patients with adenomas, with a mean age of 63.3 years.
