Summary
This summary is machine-generated.SMAD4 gene expression is significantly reduced in colorectal cancer (CRC) tissues compared to normal tissues. Lower SMAD4 levels correlate with advanced TMN stage, suggesting its potential as a diagnostic marker for CRC.
Area Of Science
- Oncology
- Molecular Biology
- Genetics
Background
- Colorectal cancer (CRC) is a leading cause of cancer mortality worldwide.
- The SMAD4 gene is a key mediator in the transforming growth factor-β (TGFβ) signaling pathway, implicated in CRC progression.
- Previous studies indicate a link between SMAD4 and CRC patient survival and disease advancement.
Purpose Of The Study
- To investigate SMAD4 gene expression in colorectal cancer tissues versus adjacent normal tissues.
- To evaluate the diagnostic potential of SMAD4 in colorectal cancer.
- To explore the correlation between SMAD4 expression and clinicopathological features, including TMN staging.
Main Methods
- Quantitative Real-Time PCR (qRT-PCR) was employed to measure SMAD4 expression levels.
- Expression analysis was conducted on 45 colorectal tumor samples and 45 adjacent normal tissue samples.
- Receiver Operating Characteristic (ROC) curve analysis was performed to assess diagnostic accuracy.
Main Results
- SMAD4 expression was found to be significantly downregulated in colorectal tumor tissues compared to adjacent normal tissues.
- A notable correlation was observed between SMAD4 gene expression levels and the TMN stage of colorectal cancer (p<0.0001).
Conclusions
- Reduced SMAD4 expression is a characteristic feature of colorectal cancer.
- SMAD4 levels demonstrate potential as a diagnostic biomarker for identifying colorectal cancer.
- Further research into SMAD4's role could enhance diagnostic strategies for colorectal cancer.

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...
Pleiotropy is the phenomenon in which a single gene impacts multiple, seemingly unrelated phenotypic traits. For example, defects in the SOX10 gene cause Waardenburg Syndrome Type 4, or WS4, which can cause defects in pigmentation, hearing impairments, and an absence of intestinal contractions necessary for elimination. This diversity of phenotypes results from the expression pattern of SOX10 in early embryonic and fetal development. SOX10 is found in neural crest cells that form melanocytes,...
