Newfound roadblock to interferon effectiveness against malignant melanoma
Researchers have uncovered a significant contributing factor to interferon resistance of malignant melanoma cells. The finding represents a step forward in understanding the molecular events that govern the growth of this type of cancer and the changes in gene expression and cellular signaling that underlie resistance to established therapies. Malignant melanoma is the deadliest form of sk...Researchers discover why melanoma is so malignant
About 60,000 Americans will be diagnosed with melanoma this year, says the American Cancer Society, and 10,000 of those cases will be fatal. If not caught in the early stages, melanoma can be a particularly virulent form of cancer, spreading through the body with an efficiency that few tumors possess. Now, researchers at Whitehead Institute for Biomedical Research have discovered one of the reaso...Stem cell microenvironment reverses malignant melanoma
Northwestern University researchers have demonstrated how the microenvironments of two human embryonic stem cell (hESC) lines (federally approved) induced metastatic melanoma cells to revert to a normal, skin cell-like type with the ability to form colonies similar to hESCs. The researchers also showed that these melanoma cells were less invasive following culture on the microenvironments of hESC...Malignant melanoma cells secrete protein required for embryo formation
A Northwestern University research group has discovered that aggressive melanoma cells secrete Nodal, a protein that is critical to proper embryo formation. An article describing this research was published today in the advanced online issue of the journal Nature Medicine. The researchers identified the potent and highly unstable embryonic growth factor by injecting aggressive melanoma c...Possible birthplace of malignant brain tumors identified
Researchers have found that abnormal stimulation of a cellular trigger that normally regulates replenishment of brain cells in adults causes invasive tumor-like growths in mice. Removing the abnormal stimulation causes the growths to regress--a finding the researchers said suggests a possible treatment for the lethal, aggressive brain tumors called malignant gliomas. Arturo Alvarez-Buylla...Blood test developed for malignant hyperthermia
Experts have developed a blood test to determine the genetical predisposition for a rare condition// called malignant hyperthermia. Malignant hyperthermia is an inherited disorder that can affect the patient during or after general anesthesia. This condition may be triggered by volatile anesthetics or depolarizing muscle relaxants that have to work together with a genetical predisposit...Malignant Mesothelioma – A New Genetic Revelatio
Malignant mesothelioma is a very aggressive tumor which is found resistant to most of the treatment, which is increasing in frequency throughout the world. The main causative agents for the development of Malignant mesothelioma is exposure to asbestos, recently a virus, simian virus 40 (SV40) is also found to be a causative agent for development of this tumor. Many people with malignan...Malignant Mesothelioma – A New Genetic Revelation

Researchers have found traces of a monkey virus that contaminated the polio vaccine in the early 50's in a common form of highly malignant human cancer that has mystically doubled in incidence over the past 30 years. Two studies, found a link between the virus, called SV40, and non-Hodgkin lymphomas, a disorder ranked fourth or fifth among cancer deaths in the United States among women and men,...Experimental Therapy Effective Against Malignant Melanoma in Horses
Dr. John L. Robertson, a professor in the Virginia-Maryland Regional College of Veterinary Medicine at Virginia Tech and director of the college's Center for Comparative // Oncology (CECO) has been studying the similarities of malignant melanoma in horses and humans and has devised an experimental treatment for it. At a presentation before the American Cancer Society in Roanoke, Va., he...SciClone and Sigma-Tau Report Thymalfasin Meets Primary Endpoint in Phase 2 Malignant Melanoma Trial
