Abstract:
The aim was to evaluate the relationship between SDF-1G801A polymorphism and its immunohistochemical expression in colorectal cancer tissues in the Tunisian cohort. The molecular and immunohistochemical analysis showed that SDF-1G801A polymorphic variant was higher in CRC patients with TNM stage II and III, the SDF-1 expression was significantly increased from normal mucosa to primary tumor (p < 0.05). CRC patients have higher frequency of A allele (52.01%) than controls (26.8%) (P = 0.0001). Thus, SDF-1 polymorphism is a risk factor of colorectal cancer susceptibility in our population, the polymorph genotype of SDF-1 maybe associated with clinical manifestations in CRC patients in Tunisia.

Translation
Translation is the process of synthesizing proteins from the genetic information carried by messenger RNA (mRNA). Following transcription, it constitutes the final step in the expression of genes. This process is carried out by ribosomes, complexes of protein and specialized RNA molecules. Ribosomes, transfer RNA (tRNA), and other proteins produce a chain of amino acids—the polypeptide—as the end product of translation.
