New Study: Herpes, the STD, May Lead to Tumors of the Heart; polyDNA Recommends Gene-Eden-VIR against the Herpes Virus

A herpes virus infection may cause primary tumors of the heart in adults. polyDNA recommends killing the herpes virus as early as possible.

Rochester, NY (PRWEB) April 14, 2013

Herpes is usually associated with genital sores, fever blisters, cold sores, sexually transmitted infections and social stigmas. However, a new study links both genital herpes and oral herpes to the development of tumors of the heart.

“This study has shown that HSV DNA is detected significantly more frequently in cardiac myxomas than in their normal counterparts.” In addition, the researchers reported that “…the detection of HSV-2 as the infectious agent in two myxoma cases reflects a novel finding.” [1]

This is important because myxomas, tumors of primitive connective tissue, are the most common type of tumor in the heart. [2]

“Of particular interest is the recognition of HSV-2 as a potential cardiovascular pathogen. The virus has been implicated in coronary artery disease and carotid atherosclerosis.” – (Journal of Biomedicine and Biotechnology)

Common clinical manifestations of myxomas are strokes, peripheral or pulmonary embolization, fever, weight loss, high sedimentation rate, anemia, and leucocytosis. [3]

The public should be aware of the fact that herpes could lead to the development of heart tumors over time. polyDNA recommends that people educate themselves about Gene-Eden-VIR, a natural remedy against the latent herpes virus.

By helping the body’s immune system target the latent herpes virus, people also lower their risk of developing fever blisters, cold sores, genital herpes symptoms, and may also help prevent strokes, fever, anemia, athererosclerosis and the development of heart tumors.

"The key to your health is to reduce the level of the chronic viruses in your body to harmless levels." - Dr. Hanan Polansky

In a post marketing clinical study, Gene-Eden-VIR was shown to be safe and highly effective against the latent herpes virus. Over 70% of Gene-Eden-VIR users reported a reduction in herpes symptoms. (4)

Each capsule of Gene-Eden-VIR contains a patented formula of five all natural ingredients including selenium, camellia sinesis extract, quercetin, cinnamomum extract, and licorice extract. In addition, each bottle is GMP Certified. (5)

Immunogene therapy combined with standard treatment is safe for patients with brain tumors, study suggests

ScienceDaily (Sep. 6, 2011) — A clinical trial has shown that a form of gene therapy is safe for treating a deadly form of brain cancer, even when combined with radiation therapy.

The phase 1b trial was conducted at the Ohio State University Comprehensive Cancer Center -- Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC -- James) and at Methodist at Hospital in Houston, TX.

The novel treatment uses an adenovirus vector called AdV-tk. The vector is taken up by cancer cells where it activates a drug that kills the cells. The vector is applied in the operating room after removing brain tumors such as glioblastoma multiforme, the most common and dangerous form of brain cancer.

The findings, published online in the Journal of Clinical Oncology, suggest that the therapy might also stimulate an immune response against the tumor.

"This is the first time that a gene therapy approach was combined with radiation in patients with newly diagnosed glioblastoma," says first author Dr. E. Antonio Chiocca, professor and chair of neurological surgery and co-director of the Dardinger Center for Neuro-oncology and Neurosciences at Ohio State.

"There had been a concern that combining these two treatments could be too toxic for patients, but this was not the case. We do not know yet if this will improve survival, but these findings are encouraging," he says.

Glioblastomas occur in about 18,500 Americans annually and kill nearly 13,000 of them yearly. Glioblastoma multiforme is the most common and lethal form of the malignancy, with an average survival of 15 months after diagnosis.

The tumors often recur because cancer cells typically migrate into adjacent brain tissue where they can give rise to a recurrent tumor. This study examines an immunogene therapy approach that is designed to kill these undetected cancer cells and prevent recurrence.

This clinical trial involved 10 patients with glioblastoma multiforme and two patients with anaplastic astrocytoma. The procedure works as follows:

After removing the tumor, the neurosurgeon injects the tumor bed with 1 milliliter (1/30th oz) of a solution containing the AdV-tk vector. The vector carries a gene from herpes simplex virus for an enzyme called thymidine kinase (the '-tk' in AdV-tk). Cancer cells infected with the vector begin making the enzyme.Patients then take the anti-herpes virus drug valacyclovir for two weeks.Inside the cancer cells, the herpes thymidine kinase enzyme converts valacyclovir into DNA building blocks that the rapidly growing cancer cells cannot use to make DNA, and this kills them.Radiation therapy begins halfway through the course of valacyclovir. The radiation damages the DNA in the cancer cells, which then try to repair it, using the toxic valacyclovir building blocks.

In addition to improved overall survival, studies revealed a significant rise in the number of T lymphocytes in the tumors. This suggests that the gene therapy stimulated an immune response against the tumor, producing an "immunogene therapy" effect.

Cancer immunogene therapy refers to genetically manipulating cancer cells to stimulate an immune response against a tumor. (Note: This differs from "immunotherapy," which attempts to stimulate the immune system directly against tumor cells.)

"If the results of another recently completed phase 2 efficacy trial are also encouraging, the next step will be to compare this therapy head-to-head with the current standard of care," Chiocca says.

Scientists use genetically altered virus to get tumors to tattle on themselves

ScienceDaily (May 12, 2011) — Scientists have used a genetically re-engineered herpes virus that selectively hunts down and infects cancerous tumors and then delivers genetic material that prompts cancers to secrete a biomarker and reveal their presence.

According to a study appearing May 11 in PLoS ONE, published by the Public Library of Science, the novel technology has the potential to vastly improve cancer diagnosis by allowing the disease to be caught at much earlier stages and to monitor the effectiveness of therapy.

Researchers at Cincinnati Children's Hospital Medical Center who conducted the study say the new technique -- developed in preclinical mouse models -- could also be more cost effective and portable than current scanning technologies. This would make it useful for diagnosing cancers in less developed parts of the world.

"Our study represents a proof-of-principle in mice, and there is certainly room for further refinement. If ultimately validated in human trials, it could have implications for people with known cancer risk or who have a history of cancer and high risk of recurrence,'' said Timothy Cripe, M.D., Ph.D., senior investigator on the study and a physician and researcher in the Division of Oncology at Cincinnati Children's.

"Early cancer detection is vital to improve cure rates because cancer stage predicts prognosis, but biomarkers are known for only a few cancer types. We were able to use a reprogrammed herpes virus administered intravenously to deliver genetic information that induces a known blood biomarker for cancer to be secreted by cancer cells," explained Dr. Cripe, who collaborated on the study with first author, Andrew Browne, Ph.D., a fourth-year medical student at the University of Cincinnati (UC) College of Medicine and a recent graduate from UC's Department of Electrical and Computer Engineering.

The researchers engineered a herpes simplex virus mutant they called rQ-M38G, reprogramming its genetic makeup so it bypasses healthy tissues and instead targets rapidly dividing cancer cells for infection. They also genetically armed the virus so it prompts cancer cells to secrete Gaussia luciferase (GLuc).

GLuc is a luminescent, easily detectable protein the researchers used as a universal blood biomarker for cancer cells infected by rQ-M38G. Because rQ-M38G/GLuc might also help shrink cancer, it is part of a new class of agents dubbed "theragnostics" that can simultaneously be used for diagnosis and therapy, Dr. Cripe said.

Initially the researchers tested rQ-M38G on laboratory cell cultures of healthy dormant human skin cells and on rapidly dividing cancer cells. Virus replication and biomarker production were very low in the dormant normal cells. In contrast, virus replication and biomarker production were much higher in tumor cell lines of malignant peripheral nerve sheath tumors, osteosarcoma (bone cancer), rhabdomyosarcoma (muscle cancer) and Ewing sarcoma.

Researchers then tested the virus's detection capabilities in mouse models of these same cancers by injecting rQ-M38G into their tail veins, and for comparison into the tail veins of healthy control mice. Non-tumor bearing mice showed background signals for the virus without significant replications or biomarker production. More than 90 percent of the tumor bearing mice showed significant virus replication and biomarker production.

The technology even worked in some mice with only microscopic amounts of cancer in their kidneys, researchers report. If it were to work as well in humans, the scientists estimate that hidden tumors less than half-inch in diameter might be detectable. Because of the anticipated immune response against the virus and the GLuc protein in humans, further refinements of the technology will likely be needed to be able to use it more than once.

The study is one more example of the expanding research into using reprogrammed HSV as novel methods to treat or diagnose cancer, especially as medicine reaches the limits of modern chemotherapies. Dr. Cripe said this creates an urgent need for new strategies against stubborn metastatic disease. Less than 30 percent of patients with metastatic cancer survive beyond five years, despite the aggressive use of modern combination therapies that include chemotherapy.

Also collaborating on the current study were Jennifer Leddon, Mark Currier, Jon Williams, Jason Frischer, and Margaret Collins all of Cincinnati Children's.

Funding support for the study came from the CancerFree Kids Pediatric Cancer Research Alliance and the National Institutes of Health.
