| خلاصه مقاله | Abstract: Colorectal cancer (CRC) is the third most common cancer and the second cause of cancer-
related death worldwide [1,2]. As early detection is associated with lower mortality, novel biomarkers
are urgently needed for timely diagnosis. This study aimed to identify hub genes as CRC biomarkers
by analyzing differentially expressed genes (DEGs).
Methods: The GSE113513 dataset was obtained from the GEO database, consisting of 14 pairs of CRC
primary lesions and non-cancerous surrounding tissue. Principal Component Analysis (PCA) assessed
the sample consistency. LIMMA package was used for statistical analysis. DEGs were identified using
| 𝑙𝑙𝑙𝑙𝑙𝑙 2 𝐹𝐹𝐹𝐹 |> 3 and adj P-value < 0.05. Gene expression and survival outcomes correlation were
determined by the Kaplan-Meier plotter.
Results: The expression profiles of 28 samples were evaluated using microarray analysis. There were
110 DEGs found in all, with 93 being down-regulated and 17 being up-regulated. Among these DEGs,
two genes, MMP7 and CDH3, have been previously linked to various cancers such as breast, lung,
pancreatic, etc. In this dataset, these genes exhibited a significant increase in their expression. As per
the information available in GeneCards, WikiPathways, and Reactome pathway databases, these genes
regulate crucial pathways, including the Wnt signaling pathway, pluripotency, cell-cell communication,
and ILK signaling. The DEGs identified in this study were found to be correlated with poor prognosis
in colorectal cancer based on the Kaplan-Meier plots.
Conclusion: The findings of our investigation indicate that the genes MMP7 and CDH3 have significant
contributions to colorectal cancer (CRC) and are connected to a poor prognosis in CRC. |
