Overexpression of CXCL8 gene in Saudi colon cancer patients
Colorectal cancer (CRC) is one of the leading causes of death in Saudi Arabia. CRC mostly affects older age groups, but now a days it also appears frequently at a young age. However, the complete genetic etiology of CRC remains unknown. To identify the genetic factors responsible for this cancer typ...

description | Colorectal cancer (CRC) is one of the leading causes of death in Saudi Arabia. CRC mostly affects older age groups, but now a days it also appears frequently at a young age. However, the complete genetic etiology of CRC remains unknown. To identify the genetic factors responsible for this cancer type and to search for biomarkers for early diagnosis and prevention, we collected sixteen CRC tumor tissue samples and six normal colon tissues and extracted mRNA and synthesized cDNA. We then performed microarray transcriptomic profiling of Saudi patients with colon cancer. Gene expression was analyzed using Partek Genomics Suite, and principal component analysis (PCA) was performed to separate the different clusters of colon cancer and healthy tissues. Distinct differences in gene expression profiles were observed between colon cancer and normal tissue samples. Subsequently, we validated gene expression using real-time PCR. We found that the C-X-C motif chemokine ligand 8 (CXCL8) gene was expressed most in CRC samples. CXCL8 expressed 25.6 folds more in CRC tissues than in healthy tissues. In conclusion, we found that CXCL8 is the chief biomarker gene that is expressed most in CRC and plays an important role in tumor progression and metastasis. |
