Cancers Originate from Somatic Mutations in a Single Cell

Cancers Originate from Somatic Mutations in a Single Cell

Cancer arises from mutations in the critical genes that allow healthy cells to escape cell cycle regulation and acquire the ability to proliferate indefinitely. Though originating from a single mutation event in one of the originator cells, cancer progresses when the mutant cell lines continue to gain more and more mutations, and finally, become malignant. For example, chronic myelogenous leukemia (CML) develops initially as a non-lethal increase in white blood cells, which progressively...

Combination Therapies and Personalized Medicine

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...

Mouse Models of Cancer Study

Mouse Models of Cancer Study

Mice have long served as models for studying human biology and pathology because of their phylogenetic and physiological similarity with humans. They are also easy to maintain and breed in the laboratory, and hence, many inbred strains are now available for research. Studies on mice have contributed immeasurably to our understanding of cancer biology.
The development of transgenic, knockout, and knock-in mice has led to an exponential increase in their use as model organisms in research,...

Cancer-Critical Genes II: Tumor Suppressor Genes

Cancer-Critical Genes II: Tumor Suppressor Genes

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...

Background:

Identifying cancer type-specific driver mutations is essential for understanding tumor pathology and developing personalized treatments.
Existing computational methods for predicting driver mutations require improvement in accuracy and specificity.

Purpose of the Study:

To develop a novel machine learning model for identifying cancer type-specific driver mutations.
To improve the accuracy of driver mutation detection using a new sequence co-evolution feature.

Main Methods:

Developed a machine learning framework incorporating a novel feature based on sequence co-evolution analysis.
Trained and validated the model on a large dataset of 28,000 tumor samples across 66 cancer types.

Main Results:

The developed machine learning framework demonstrated state-of-the-art performance, outperforming current leading methods.
Mutations identified via sequence co-evolution were frequently located at interfaces of tissue-specific protein-protein interactions involved in oncogenesis.

Conclusions:

The novel sequence co-evolution feature significantly enhances the identification of cancer type-specific driver mutations.
The findings facilitate the identification of driver mutations in newly sequenced tumor samples, aiding in patient-specific treatment strategies.
