background: mucinous adenocarcinoma colorectal cancer present at a more colorectal advanced stage of disease and showe a poorer prognosis than those with other types of carcinoma. the purpose of the present study was to clarify the clinicopathological characteristics of mucinous colorectal carcinoma in the iranian population. methods: 110 patients with mucinous adenocarcinoma were selected from...

Background and Objective: Mesenchymal stem cells (MSCs) promote metastasis in colorectal cancer; however, the mechanism underlying this process is not fully understood. Epithelial to mesenchymal transition (EMT) is a key step in tumor acquisition of metastatic phenotype. We aimed to investigate the effect of MSCs on the expression of EMT markers, as well as cancer stem cell markers in HT-29 col...

Background: Activation of the ubiquitin-proteasome pathway in various malignancies, including colorectal cancer, is established. This pathway mediates the degradation of damaged proteins and regulates growth and stress response. The novel human gene, UBE2Q2, with a putative ubiquitin-conjugating enzyme activity, is reported to be overexpressed in some malignancies. We sought to investigate the ...

it is clear that colorectal cancer (crc) develops through multiple genetic and epigenetic pathways. these pathways may be determined on the basis of three molecular features: (i) mutations in dna mismatch repair genes, leading to a dna microsatellite instability (msi) phenotype, (ii) mutations in apc and other genes that activate wnt pathway, characterized by chromosomal instability (cin) pheno...

Background: To determine the expression of cancer stem cell marker Leucine-rich repeat-containing G-protein coupled receptor 5 (Lgr5) in colorectal carcinoma samples compared to normal adjacent tissue and any possible association with clinicopathological findings. Methods: This study was performed on forty samples of cancerous colorectal tissues (case group) and their adjacent normal mucosa (c...

‌Background & objectives: Colorectal cancer (CRC) is the most common gastric cancer and third lethal cancer worldwide. Despite development in diagnostic and treatment methods, due to the lack of typical symptoms in the early stages, most patients are diagnosed in the end stages. Therefore, finding simple, inexpensive, highly sensitive and specific diagnostic methods for early detection and prog...
