Insights

Gene fusions are rare but promising targets for colorectal cancer (CRC) treatment, offering new therapeutic avenues beyond conventional chemotherapy. This review explores their role in CRC pathogenesis, detection, and clinical application.

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • Colorectal cancer (CRC) is a major global health concern, ranking as the third leading cause of cancer death.
  • Current CRC treatments rely on chemotherapy, which faces challenges due to acquired resistance and significant toxicity.
  • Identifying novel, actionable therapeutic targets is crucial for improving CRC patient outcomes.

Purpose of the Study:

  • To review the emerging role of gene fusions as potential therapeutic targets in colorectal cancer.
  • To explore the involvement of gene fusions in CRC pathogenesis and their clinical implications.
  • To discuss current and future strategies for screening and identifying gene fusions in CRC.

Main Methods:

  • Comprehensive literature review focusing on gene fusions in colorectal cancer.
  • Analysis of studies investigating the molecular mechanisms and clinical significance of gene fusions.
  • Evaluation of diagnostic and screening methodologies for gene fusion detection in CRC.

Main Results:

  • Gene fusions, though rare, are increasingly recognized as recurrent markers across various tumor types, including CRC.
  • These genetic alterations hold potential for targeted therapies due to their specific actionability.
  • Advances in screening technologies are improving the detection rates and clinical utility of gene fusions in CRC.

Conclusions:

  • Gene fusions represent a promising area for novel therapeutic strategies in colorectal cancer.
  • Further research into their pathogenesis and clinical utility is warranted to fully exploit their potential.
  • Integrating gene fusion analysis into routine CRC diagnostics may facilitate personalized treatment approaches.

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

Combination Therapies and Personalized Medicine

Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

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...

Reporter Genes02:11

Reporter Genes

Reporter genes are a type of protein-coding gene that are often tagged to a gene of interest. Once inside a target cell, reporter genes usually produce visually identifiable characteristics like fluorescence and luminescence when expressed along with the gene of interest. Thus, reporter genes “report” the presence or absence of genes of interest in an organism, determine the gene expression pattern, or track the physical location of a DNA segment or protein in the cell.

Cancer-Critical Genes I: Proto-oncogenes

Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...

Gene Therapy00:59

Gene Therapy

Gene therapy is a technique where a gene is inserted into a person’s cells to prevent or treat a serious disease. The added gene may be a healthy version of the gene that is mutated in the patient, or it could be a different gene that inactivates or compensates for the patient’s disease-causing gene. For example, in patients with severe combined immunodeficiency (SCID) due to a mutation in the gene for the enzyme adenosine deaminase, a functioning version of the gene can be...
