Researchers identify cancer-associated mutations

Two new mutations that collectively occur in 71 percent of malignant melanoma tumors have been discovered in what scientists call the "dark matter" of the cancer genome, where cancer-related mutations haven't been previously found.

Intermittent therapy may be answer to treating drug-resistant melanoma

Findings from a study carried out in mice suggest that an intermittent dosing strategy may be the answer to combating lethal tumor resistance to the BRAF inhibitor vemurafenib, in patients with late-stage BRAF-mutated melanoma.

Melanomas that develop resistance to vemurafenib also become addicted to the drug

Researchers in California and Switzerland have discovered that melanomas that develop resistance to the anti-cancer drug vemurafenib (marketed as Zelboraf), also develop addiction to the drug, an observation that may have important implications for the lives of patients with late-stage disease.

Melanoma patients may benefit from microRNA-26a replacement therapy

A University of Colorado Cancer Center study in this month's edition of the Journal of Investigative Dermatology describes a new target and potential treatment for melanoma, the most dangerous form of skin cancer. MicroRNA can decide which genes in a cell's DNA are expressed and which stay silent. Melanoma tends to lack microRNA-26a, which makes the gene SODD go silent.

MITF protein may help develop effective drug treatments for melanoma

Scientists at The University of Manchester have identified a protein that appears to hold the key to creating more effective drug treatments for melanoma, one of the deadliest cancers.

Pairing statins with cyclin-dependent kinase inhibitors might effectively treat melanomas

A novel approach to identifying potential anticancer drug combinations revealed that pairing cholesterol-reducing drugs called statins with cyclin-dependent kinase inhibitors might provide an effective approach to treating intractable melanomas driven by mutations in the NRAS and KRAS gene.

Scientists eliminate metastasis in laboratory experiments

In laboratory experiments, scientists have eliminated metastasis, the spread of cancer from the original tumor to other parts of the body, in melanoma by inhibiting a protein known as melanoma differentiation associated gene-9 (mda-9)/syntenin. More than 1 million cases of skin cancer are diagnosed each year in the U.S., and melanoma is the deadliest form.

New UTSW model can predict progression of skin cancer in patients

UT Southwestern Medical Center scientists led by Dr. Sean Morrison, director of the Children's Medical Center Research Institute at UT Southwestern, have developed an innovative model for predicting the progression of skin cancer in patients.

Nonclinical data on Provectus PV-10 oncology drug presented at 27th SITC

Provectus Pharmaceuticals, Inc., a development-stage oncology and dermatology biopharmaceutical company, presented nonclinical data on PV-10 at the Society for Immunotherapy of Cancer (SITC) 27th Annual Meeting on October 26 and 27, 2012 in North Bethesda, MD.

Tel Aviv University researcher discovers homing device that draws cancer

The process of metastasis, by which cancer cells travel from a tumor site and proliferate at other sites in the body, is a serious threat to cancer patients. According to the National Cancer Institute, most recurrences of cancer are metastases rather than "new" cancers.

Study finds major reason why melanoma is largely resistant to chemotherapy

Researchers with UC Irvine's Chao Family Comprehensive Cancer Center have identified a major reason why melanoma is largely resistant to chemotherapy.

ALDH enzyme marks melanoma stem cells

Cancer stem cells are defined by three abilities: differentiation, self-renewal and their ability to seed a tumor. These stem cells resist chemotherapy and many researchers posit their role in relapse. A University of Colorado Cancer Center study recently published in the journal Stem Cells, shows that melanoma cells with these abilities are marked by the enzyme ALDH, and imagines new therapies to target high-ALDH cells, potentially weeding the body of these most dangerous cancer creators.

Study demonstrates how Elesclomol blocks oxidative phosphorylation in melanoma

A laboratory study led by UNC medical oncologist Stergios Moschos, MD, demonstrates how a new targeted drug, Elesclomol, blocks oxidative phosphorylation, which appears to play essential role in melanoma that has not been well-understood. Elesclomol (Synta Pharmaceuticals, Lexington, MA) was previously shown to have clinical benefit only in patients with normal serum lactate dehydrogenase (LDH), a laboratory test routinely used to assess activity of disease.

Combination of Zelboraf and immunotherapy increases tumor responses and survival in MM

Combining the recently approved BRAF inhibitor, Zelboraf with an engineered T cell immunotherapy to treat metastatic melanoma significantly increased tumor responses and survival in an animal model, researchers at UCLA's Jonsson Comprehensive Cancer Center have shown.

MASL protein from plant's seeds may halt spread of melanoma

An international team of scientists led by Gary Goldberg, PhD, of the University of Medicine and Dentistry of New Jersey-School of Osteopathic Medicine (UMDNJ-SOM), has found that a protein from the seeds of a plant used for centuries in traditional medicines may be able to halt the spread of melanoma, a lethal form of skin cancer.

New large animal model for human cancer studies

A naturally occurring line of immunodeficient pigs can support the growth of human tumors injected under their skin, offering a promising new large animal model for studying human cancers and testing new drugs and treatment strategies.

Study identifies MDM4 protein as promising target for treatment of melanoma

A melanoma is a malignant form of skin cancer and is one of the most aggressive types of tumors there is. Treatment is particularly difficult, because melanomas are usually resistant against conventional chemotherapy treatments.

Sox10 gene plays a central role in melanoma

Black skin cancer, also known as melanoma, is particularly aggressive and becoming increasingly common in Switzerland. Despite intensive research, however, there is still no treatment. Researchers from the University of Zurich have now discovered a gene that plays a central role in black skin cancer. Suppressing this gene in mice inhibits the development of melanoma and its proliferation - a discovery that could pave the way for new forms of therapy.

Secreted vesicles play role in spread of cancer

Cancer researchers have known for well over a century that different tumor types spread only to specific, preferred organs. But no one has been able to determine the mechanisms of organ specific metastasis, the so-called "soil and seed" theory of 1889. New details that could help shed light on this hypothesis have been provided by a team of researchers from Weill Cornell Medical College, Memorial Sloan-Kettering Cancer Center, and their collaborators, proposing a new mechanism controlling cancer metastasis that offers fresh diagnostic and treatment potential.

Eye color linked to high-risk for skin conditions

Eye color may be an indicator of whether a person is high-risk for certain serious skin conditions. A study, led by the University of Colorado School of Medicine, shows people with blue eyes are less likely to have vitiligo.
