Insights

Researchers identified ETV4 and MYEOV as novel colorectal cancer genes. Knocking down these genes significantly reduced cancer cell proliferation and invasion, suggesting potential new therapies for colon cancer.

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • Colorectal cancer (CRC) remains a significant health burden globally.
  • Identifying novel genes driving CRC pathogenesis is crucial for developing targeted therapies.

Purpose of the Study:

  • To identify novel genes associated with colorectal cancer using bioinformatics and molecular techniques.
  • To investigate the functional roles of identified genes, ETV4 and MYEOV, in CRC cell behavior.

Main Methods:

  • Utilized NCBI's UNIGENE cDNA libraries and Digital Differential Display (DDD) to screen for disease-associated genes.
  • Quantified gene expression of ETV4 and MYEOV in matched normal and neoplastic human colon tissues using real-time PCR.
  • Assessed the impact of siRNA-mediated knockdown of ETV4 and MYEOV on colorectal cancer cell proliferation and invasion.

Main Results:

  • ETV4 and MYEOV were identified as novel colorectal cancer-associated genes.
  • Gene expression of ETV4 and MYEOV was significantly elevated in colon neoplasia compared to normal tissue (p<0.05).
  • Knockdown of ETV4 decreased cell proliferation by 90% and invasion by 67%. Knockdown of MYEOV decreased proliferation by 48% and invasion by 36% (p<0.05).

Conclusions:

  • ETV4 and MYEOV play significant roles in promoting colorectal cancer cell proliferation and invasion.
  • These findings highlight ETV4 and MYEOV as promising novel therapeutic targets for colorectal cancer intervention.

Cancer Cell Migration through Invadopodia01:35

Cancer Cell Migration through Invadopodia

Invadosome is a broad category of cell surface structures with proteolytic activity that  degrades the extracellular matrix (ECM). Invadosomes are present in normal cell types, including macrophages, endothelial cells, and neurons, as well as tumor cells. Although the macrophage podosomes and tumor cell invadopodia are classified as invadosomes, they have different structures, molecular pathways, and functions. Podosomes are short structures that last for a few minutes. However, invadopodia can...

In-vitro Mutagenesis

To learn more about the function of a gene, researchers can observe what happens when the gene is inactivated or “knocked out,” by creating genetically engineered knockout animals. Knockout mice have been particularly useful as models for human diseases such as cancer, Parkinson’s disease, and diabetes.
Tumor Progression02:07

Tumor Progression

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...

Metastasis02:30

Metastasis

Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
Loss of Tumor Suppressor Gene Functions01:12

Loss of Tumor Suppressor Gene Functions

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...
