Summary
Gene expression profiling (GEP) aids melanoma treatment decisions. DecisionDx-Melanoma, a GEP test, shows clinical utility in managing cutaneous melanoma patients.
Area of Science:
- Oncology
- Dermatology
- Genetics
Background:
- Melanoma treatment and staging are evolving rapidly.
- Patient outcomes vary significantly due to unknown factors, complicating management decisions.
- Gene expression profiling (GEP) has shown predictive capabilities in melanoma.
Purpose of the Study:
- To review the clinical evidence for DecisionDx-Melanoma.
- To analyze the utility of this GEP test in cutaneous melanoma management.
Main Methods:
- Review of clinical evidence for DecisionDx-Melanoma.
- Analysis of prospective studies on GEP test utility.
Main Results:
- GEP tests, including DecisionDx-Melanoma, have demonstrated the ability to predict patient outcomes.
- Adoption of GEP has led to changes in clinical practice patterns and patient management.
Conclusions:
- DecisionDx-Melanoma is the only GEP test for cutaneous melanoma with prospective studies.
- Clinical evidence supports the utility of DecisionDx-Melanoma in guiding melanoma patient management.

Overview
Gene expression is the process in which DNA directs the synthesis of functional products, that is, proteins. Cells can regulate gene expression at various stages. It allows organisms to generate different cell types and enables cells to adapt to internal and external factors.
Genetic Information Flows from DNA to RNA to Protein
A gene is a stretch of DNA that serves as the blueprint for functional RNAs and proteins. Since DNA is made up of nucleotides and proteins consist of amino...

11.4K
A gene is a stretch of DNA that serves as the blueprint for functional RNAs and proteins. Since DNA is comprised of nucleotides and proteins are comprised of amino acids, a mediator is required to convert the information encoded in DNA into proteins. This mediator is the messenger RNA (mRNA). mRNA copies the blueprint from DNA by a process called transcription. In eukaryotes, transcription occurs in the nucleus by complementary base-pairing with the DNA template. The mRNA is then...

01:58Cell Specific Gene Expression
16.5K
Multicellular organisms contain a variety of structurally and functionally distinct cell types, but the DNA in all the cells originated from the same parent cells. The differences in the cells can be attributed to the differential gene expression. Liver cells, whose functions include detoxification of blood, production of bile to metabolize fats, and synthesis of proteins essential for metabolism, must express a specific set of genes to perform their functions. Gene expression also varies with...

02:35Chromatin Position Affects Gene Expression
24.8K
Chromatin is the massive complex of DNA and proteins packaged inside the nucleus. The complexity of chromatin folding and how it is packaged inside the nucleus greatly influences access to genetic information. Generally, the nucleus' periphery is considered transcriptionally repressive, while the cell's interior is considered a transcriptionally active area.

02:51mRNA Stability and Gene Expression
6.6K
The structure and stability of mRNA molecules regulates gene expression, as mRNAs are a key step in the pathway from gene to protein. In eukaryotes, the half-life of mRNA varies from a few minutes up to several days. mRNA stability is essential in growth and development. The absence of the proteins regulating its stability, such as tristetraprolin in mice, can cause systemic issues, including bone marrow overgrowth, inflammation, and autoimmunity.
