Dysregulation of β-catenin, epithelial-mesenchymal transition (EMT), and adenomatous polyposis coli (APC) are crucial in CRC development. Mutations in the APC gene lead to aberrant β-catenin expression, a key player in CRC pathogenesis. β-catenin not only influences canonical Wnt signaling but also regulates EMT. This study investigated the correlation between APC mutations, β-catenin dysregulation, and EMT induction in CRC.  \nMethodology  \nTissue samples from 96 CRC patients and 40 para-cancerous normal tissues were collected and subjected to immunohistochemistry to assess β-catenin, E-cadherin, ZEB1, Snail, and vimentin expression. Genomic DNA was extracted and analyzed for APC mutations. Next-generation sequencing was employed for data analysis.  \nResults  \nAberrant β-catenin expression was found in 82.3% of CRC cases and correlated with advanced clinicopathological factors. Aberrant β-catenin expression was associated with age (p=0 .01), tumor invasion depth (p=0 .03), nodal/distant metastasis (p=0 .001 and 0 .004), and vascular invasion (p=0 .001) . Aberrant β -catenin was correlated with EMT status. A positive correlation was observed between aberrant β-catenin expression and ZEB1 (p=0 .001), Snail (p=0 .001), vimentin (p=0 .001), and loss of membranous E-cadherin (p=0001) . Coexistence of aberrant β-catenin and EMT markers was associated with advanced CRC progression. Cancerous tissues displayed higher aberrant β-catenin and EMT markers expression than paracancerous tissues. APC mutations were present in 59.3% of cases, with 91 .2% of mutated APC cases showing aberrant β-catenin expression. The coexistence of APC mutation and aberrant β-catenin expression was correlated with the clinical outcomes of CRC patients. Mutated APC cases exhibited significantly increased EMT marker expression.  \nConclusion  \nThis study underscores the importance of aberrant β-catenin expression in CRC progression, linked to APC mutations and EMT induction. Understanding these relationships could aid in developing targeted therapies for CRC.  \nCategories: Gastroenterology, Genetics, Pathology  \nKeywords: mutation, apc, epithelial mesenchymal transition, β-catenin, colorectal cancer  \nIntroduction  \nColorectal cancer (CRC) remains a formidable global health challenge, accounting for a significant number of cancer-related deaths worldwide. Understanding the intricate molecular mechanisms governing CRC development is crucial to advance early diagnosis, treatment, and prevention strategies. Among the key molecular players that drive colorectal tumorigenesis dysregulation of β-catenin signaling, epithelialmesenchymal transition (EMT) and adenomatous polyposis coli (APC), have emerged as focal points of research due to their pivotal roles in this malignancy [1] . β-catenin, a multifunctional protein encoded by the CTNNB1 gene, plays a central role in a multitude of cellular processes. One of its primary functions is its participation in the canonical Wnt signaling pathway, where it acts as a key regulator.
