Mesothelioma Gene

One approach to gene therapy uses special viruses that have been modified in the lab. Gene therapy treats the disease through the introduction of new cells to kill cancer cells or enable more effective use of other treatment types.

Suicide gene therapy provides amazing potential for new and effective treatments for all kinds of cancer including mesothelioma and lung cancer.

Mesothelioma gene. Mesothelioma gene therapy uses genes from healthy cells to help kill cancerous genes within mesothelioma cancer cells by turning on the newly introduced genetic materials. The virus is injected into the pleural space and infects the mesothelioma cells. While the gene therapy didnt lead to a complete disease response it did help stop mesotheliomas growth in many cases.

The gene is located on the short arm of chromosome three. This gene is overexpressed in mesothelioma tumors and aids the cancer cells proliferation. Gene therapy is an exciting area of research especially for patients living with diseases like mesothelioma.

A newer type of treatment being tested on mesothelioma is gene therapy which attempts to add new genes to cancer cells to make them easier to kill. Gene manipulation is becoming easier safer and faster as technology improves. Mesothelioma gene therapy is an emerging treatment type that is currently available to patients through participation in clinical trials.

For example if a tumor suppressing gene is damaged this is a sign of a more aggressive disease. In a 2011 study conducted at the university of hawaii cancer center and fox chase cancer center in philadelphia researchers discovered people who carry a mutation in a gene called bap1 are susceptible to developing mesothelioma. Ezh2 is connected to the loss of bap1 which is another gene.

How tazemetostat works for mesothelioma treatment. Bap1 gene and mesothelioma. Doctors can also look for high levels of genes that create immune suppressing proteins like pd l1 and b7.

When introduced to the body the genes cause the mesothelioma cells to produce a protein that prohibits the cancerous cells from replicating. Doctors can predict the aggressiveness of a mesothelioma by studying the cells gene expression.

In recent years a gene called bap1 was discovered that is also known to cause malignant mesothelioma among other cancers.

Mesothelioma genetic. Using genetics to treat mesothelioma. Although rare compared to asbestos exposure a mutation in the bap1 gene could explain a diagnosis of mesothelioma and risk to other family members especially if there was no exposure to asbestos. The genetic components of malignant mesothelioma are not well understood.

Signs and symptoms of mesothelioma may. Asbestos is the only proven cause of mesothelioma but not everyone exposed to asbestos later develops this cancerin fact a large majority of exposed people arent affected by the disease. This fact is why researchers investigate whether mesothelioma is hereditary.

A study published in june 2017 in the journal nature details why a person with bap1 mutations becomes more resistant to chemotherapy a common problem with mesothelioma patients. In addition genetic testing can be used to distinguish mesothelioma. Cancer researchers can biopsy and test tumors for specific genetic patterns using these patterns to diagnose and stage mesotheliomathis information is stored in genomic libraries and as more patients contribute their dna samples to the databases their accuracy in diagnosing mesothelioma improves.

Mesothelioma is a type of cancer that develops from the thin layer of tissue that covers many of the internal organs known as the mesothelium. Asbestos is the most important risk factor and cause of this cancer but individual genetics likely also play a role. Less commonly the lining of the abdomen and rarely the sac surrounding the heart or the sac surrounding the testis may be affected.

The most common area affected is the lining of the lungs and chest wall. Although genes do not directly cause malignant mesothelioma genetic factors influence cancer development after carcinogen.
