Summary
Discoidin Domain Receptor 1 (DDR1) is highly expressed in most colon cancers, correlating with poorer event-free survival. This suggests DDR1
Area of Science:
- Oncology
- Molecular Biology
- Cancer Research
Background:
- Extracellular matrix components, like collagens, are crucial in the tumor microenvironment, influencing tumor progression and metastasis.
- Discoidin Domain Receptor 1 (DDR1) is a receptor tyrosine kinase implicated in cell-matrix interactions and cancer development.
Purpose of the Study:
- To investigate the clinical and prognostic significance of Discoidin Domain Receptor 1 (DDR1) expression in colon cancer.
- To explore the association of DDR1 expression with specific molecular and morphological profiles in colon adenocarcinomas.
- To assess DDR1's potential as a prognostic biomarker in colon cancer.
Main Methods:
- Immunohistochemistry was used to evaluate DDR1 expression in 292 colonic adenocarcinoma samples.
- Laser capture microdissection analyzed DDR1 mRNA expression in tumor and stromal cells.
- Modified Boyden chamber assays assessed the impact of DDR1 on colon adenocarcinoma cell invasion.
Main Results:
- High DDR1 expression was observed in 82.2% of colon adenocarcinomas.
- High DDR1 immunostaining correlated with male sex, left-sided tumors, BRAF wild-type, KRAS mutated status, and Annexin A10 negativity.
- High DDR1 expression was significantly associated with shorter event-free survival.
- DDR1 mRNA expression was predominantly found in adenocarcinoma cells, not stromal cells.
- DDR1 expression was shown to support the invasive capacity of colon adenocarcinoma cells.
Conclusions:
- Discoidin Domain Receptor 1 (DDR1) is frequently overexpressed in colon adenocarcinomas.
- High DDR1 expression serves as an indicator of worse event-free survival in colon cancer patients.
- DDR1 plays a role in supporting colon adenocarcinoma cell invasion.

Role Of Notch Signalling In Intestinal Stem Cell Renewal
2.2K
Notch signaling was first discovered in Drosophila melanogaster, where it is involved in cell lineage differentiation. Notch signaling regulates the maintenance and differentiation of intestinal stem cells or ISCs by controlling the expression of atonal homolog 1 or Atoh1. Atoh1 directs cells to differentiate into secretory cells.
Direct cell-to-cell contact is needed for the activation of Notch signaling. The signal is initiated when a notch ligand binds to a receptor on an adjacent cell, also...

Inflammatory Bowel Disease II: Crohn's Disease

Introduction
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.

Tumor Progression
6.5K
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
