Discovering the Link to Mesothelioma Growth

Discovering the Link to Mesothelioma Growth

Italian researchers have found that a molecule called cycle adenosine monophosphate (cAMP) is involved in the growth of mesothelioma.

cAMP acts as a messenger in our cells and affects different processes in the body. When the cAMP pathway is too active, it can contribute to the growth and spread of tumors.

In this study, researchers looked at the levels of cAMP in mesothelioma tumors caused by toxic fibers like asbestos.

Mesothelioma is an aggressive cancer that grows on the lining of internal organs like the lungs and abdomen. It is caused by exposure to asbestos. Asbestos is a naturally occurring mineral that is toxic to humans.

Mesothelioma is a rare disease, so we do not know very much about how it develops or the best ways to treat it. Doctors also have a hard time figuring out how well a patient will respond to treatment. Because of this uncertainty, patients with mesothelioma usually have a poor outlook.

How cAMP Influences Tumor Growth

To better understand the role of cAMP in mesothelioma, the researchers looked at 10 mesothelioma patients who live in Biancavilla in Italy. The patients were between 50 and 93 years old.

The researchers found that five out of ten tumors had high levels of cAMP, while the other five had low levels. They also found that patients with high cAMP levels had shorter survival times compared to those with low levels. Patients with high cAMP levels survived for 7.5 months on average, while patients with low cAMP levels survived for 18 months.

This study shows that high levels of cAMP in mesothelioma tumors caused by toxic fibers are related to worse outcomes for patients. This research helps us understand the disease better and may lead to new ways to treat and improve the prognosis of mesothelioma in the future.

    Mesothelioma Blood Test May Be Possible

    ByAlex Strauss

    An international team of researchers is studying the proteins found on the surface of cancer cells in an effort to improve mesothelioma diagnosis. The team, made up of scientists from the US, Switzerland, Italy and Chile, has just published their findings on a new kind of test to identify protein-derived mesothelioma biomarkers in blood serum. Mesothelioma is an aggressive cancer of the membranes around organs. Because the most common mesothelioma biomarker, mesothelin, is also overproduced by other kinds of cancer cells, it has only limited diagnostic value. A test to identify a set of proteins produced specifically by mesothelioma cells could greatly improve diagnostic accuracy. Led by Ferdinando Cerciello and Bernd Wollscheid of the Institute of Molecular Systems Biology in…

    Needle Biopsy “Simple, Safe & Accurate” for Mesothelioma

    ByAlex Strauss

    Mesothelioma researchers in China say a biopsy method that involves a single skin puncture can produce good diagnostic results for mesothelioma patients with little pain or risk. The study focused on percutaneous (through the skin) biopsy in patients who had unexplained fluid buildup or swelling in their abdomens. Abdominal distension and fluid buildup (called ascites) can be signs of peritoneal mesothelioma, a rare but aggressive cancer of the abdominal lining caused by exposure to asbestos. Peritoneal mesothelioma accounts for less than 30% of all mesothelioma cases. Because the symptoms may be vague and often develop many decades after asbestos exposure, peritoneal mesothelioma can be especially challenging to diagnose.  Misdiagnosis and under-diagnosis are not uncommon. In the newest study on percutaneous…

    Inflammation Both “Friend and Foe” in Mesothelioma

    ByAlex Strauss

    An immune system response that causes mesothelioma symptoms such as fever, fatigue, and weight loss may also be helpful to clinicians as a way to find and treat the disease. Scientists with The Asbestos Diseases Research Institute in Sydney, Australia make that case that both systemic inflammation (throughout the body) and at the site of a tumor – has long been associated with mesothelioma and other cancers. Inflammation results when the body attempts to address the imbalances of cancer by producing more of certain immune system cells. Some inflammatory markers, such as CD+8 T-cells and C-reactive protein, have been linked to better prognosis in mesothelioma. Other inflammatory markers, such as certain macrophages and a high neutrophil-to-lymphocyte ratio, can signal the…

    Could Statin Drugs Help Fight Mesothelioma?

    ByAlex Strauss

    A new study suggests that some of the most popular drugs used to treat high cholesterol may also help combat deadly malignant mesothelioma. That finding comes from Japanese research, published recently in the medical journal, Cancer Letters. The study found a “synergistic effect” in mesothelioma cells between two statin drugs, atorvastatin (Lipitor) and simvastatin (Zocor) and gamma tocotrienol (y-T3), a form of Vitamin E. “Statin+y-T3 combinations induced greater cell growth inhibition more than each single treatment,” write the authors in the summary of their findings. The combination of statin drugs and gamma-tocotrienol appears to work by inhibiting an important metabolic pathway inside the mesothelioma cells, making it impossible for them to synthesize or utilize certain critical molecules. When the researchers…

    Scientists Test New Skin Delivery for Mesothelioma Drug

    ByAlex Strauss

    Researchers at Griffith University are working on a new kind of mesothelioma treatment – one that could be delivered through the skin. The report in the Courier Mail makes reference to animal research on “certain small molecules” that reportedly have the potential to penetrate the skin and target the mitochondria of mesothelioma cells. Mitochondria are one of the most important power sources for cells, producing adenosine triphosphate, a source of chemical energy. The Griffith University project, under the leadership of Medical Professor Jiri Neuzil, is focusing on a drug that would be applied to the skin as a patch or cream. The drug would enter the blood stream through the skin and would target only mesothelioma cells. Studies of the…

    New Prognostic Factor in Peritoneal Mesothelioma

    ByAlex Strauss

    Malignant peritoneal mesothelioma is a rare form of mesothelioma that attacks the membrane that lines the abdomen and surrounds internal organs. The outlook for this rare malignancy, which affects fewer than 500 Americans annually, has been improved by the treatment combination of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). The combination has produced 5-year overall survival rates ranging from 29% to 63%. But not all peritoneal mesothelioma patients are good candidates for CRS/HIPEC. The challenge, for clinicians, is identifying which patients are likely to benefit from the procedure (or even be cured) and which are not. In an effort to help answer that question, French researchers recently tested the prognostic value of the glucose transporter protein GLUT1 as well as…
