Relationships among mutation status, expression of RAS pathway signaling molecules, and clinicopathological features and prognosis of patients with colorectal cancer.

Background: The RAS/RAF/MEK/ERK and PI3K/AKT/mTOR signaling pathways all belong to mitogen-activated protein kinase (MAPK) signaling pathways, Mutations in any one of the upstream genes (such as the gene or the gene) may be transmitted to the protein through transcription or translation, resulting in abnormal activation of the signaling pathway. This study investigated the relationship between the gene mutation and the clinicopathological features and prognosis of colorectal cancer (CRC), and the effect of mutations on its associated proteins in CRC, with an aim to clarify the cause of tumor progression and drug resistance caused by mutation of the gene.

Aim: To investigate the gene and RAS pathway signaling molecules in CRC and to analyze their relationship with clinicopathological features and prognosis.
