Summary
Gene microarray technology enables the measurement of gene expression for nearly all human genes. This approach is revealing novel tumor subclasses and identifying genes for predicting cancer behavior.
Area of Science:
- Genomics
- Molecular Biology
- Oncology
Background:
- The Human Genome Project identified thousands of genes, many with unknown functions.
- Many genes with potential diagnostic or prognostic value for malignancies remain undiscovered.
- Understanding gene function is crucial for advancing cancer diagnosis and treatment.
Purpose of the Study:
- To review recent findings using gene microarray technology in cancer research.
- To discuss the potential of gene microarrays for discovering novel molecular classifications of human malignancies.
- To highlight the role of gene expression profiling in identifying new biomarkers for cancer.
Main Methods:
- Utilizing cDNA microarray technology for large-scale gene expression measurement.
- Analyzing gene expression patterns across various human tumors, including breast carcinoma, colon carcinoma, lymphoma, leukemia, and melanoma.
- Genomic-scale analysis to identify differentially expressed genes.
Main Results:
- Gene microarray analysis has revealed novel molecular-based subclasses of tumors.
- Specific genes have been identified as potentially useful for predicting clinical behavior in cancers.
- The technology allows for efficient measurement of expression for almost every gene in the human genome.
Conclusions:
- Gene microarray technology is a powerful tool for dissecting tumor heterogeneity.
- This technology is expected to drive the development of new molecular classifications for human malignancies.
- Future applications include improved diagnostics, prognostics, and targeted therapies for cancer.

02:18Cancer
Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.
02:07Tumor 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...

01:33Cancer-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.

02:43Mouse 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,...

02:50Combination 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...
