NCI, Genesis Biopharma sign CRADA agreement to develop cancer immunotherapies

Genesis Biopharma, Inc., a biotechnology company developing targeted cancer immunotherapies, today announced it has signed a Cooperative Research and Development Agreement (CRADA) with the National Cancer Institute.

Receptor GPR56 could have a critical role in cancer progression

Melanoma is devastating on many fronts: rates are rising dramatically among young people, it is deadly if not caught early, and from a biological standpoint, the disease tends to adapt to even the most modern therapies, known as VEGF inhibitors.

Study: Early-stage melanomas can help predict tumor metastasis

Wanderlust in a person can be admirable or romantic. In a cancerous tumor, it may be lethal. Most deaths from cancer result from tumor cells that have strayed from their original location to insinuate their way into distant tissues. With few exceptions, however, doctors have little way of determining whether a newly formed tumor is more likely to remain idle or send invader cells to other parts of the body.

Specific miRNAs play a key role in melanoma metastasis

Researchers at the NYU Cancer Institute, an NCI-designated cancer center at NYU Langone Medical Center, identified for the first time the key role specific microRNAs play in melanoma metastasis to simultaneously cause cancer cells to invade and immunosuppress the human body's ability to fight abnormal cells.

Scientists pioneer way to find more chromosomal aberrations in tumors

Washington University Pediatric Cancer Genome Project scientists pioneer way to find more chromosomal aberrations in tumors; results likely to advance understanding of cancer.

NYU Cancer Institute scientists present new research findings at ASCO 2011

Experts from The Cancer Institute, an NCI-designated cancer center, at NYU Langone Medical Center presented new research findings at the 47th American Society of Clinical Oncology (ASCO) 2011 Annual Meeting in Chicago, IL.

Senescent melanoma cells express an inflammatory secretome

Malignant melanoma is a highly aggressive and notoriously chemoresistant form of cancer. In this paper, Ohanna et al. reveal that anti-melanoma drugs may, paradoxically, induce a senescence-associated secretory profile ("secretome") that can ultimately promote metastasis and contribute to melanoma relapse.

Leucine deprivation triggers apoptosis in melanoma cells

Whitehead Institute researchers have found that depriving human melanoma cells of the essential amino acid leucine can be lethal to the cells, suggesting a possible strategy for therapeutic intervention.

Long non-coding RNA promotes melanoma cell survival and invasion

Traditionally, RNA was mostly known as the messenger molecule that carries protein-making instructions from a cell's nucleus to the cytoplasm. But scientists now estimate that approximately 97 percent of human RNA doesn't actually code for proteins at all. A flurry of research in the past decade has revealed that some types of non-coding RNAs switch genes on and off and influence protein function.

ISC-4 topical compound may prevent skin cancer lesion formation

While incidents of melanoma continue to increase despite the use of sunscreen and skin screenings, a topical compound called ISC-4 may prevent melanoma lesion formation, according to Penn State College of Medicine researchers.

Plasmid containing Sindbis replicase genes can destruct lung cancer

Alpha viruses, such as Sindbis virus, carry their genetic information on a single strand of RNA. On infection they use a protein, replicase, to produce double stranded RNA which is used as genetic material to make more viruses. However the body recognizes dsRNA as foreign, and infected cells initiate an immune response.

Zebrafish model of human melanoma reveals new cancer gene

Looking at the dark stripes on the tiny zebrafish you might not expect that they hold a potentially important clue for discovering a treatment for the deadly skin disease melanoma. Yet melanocytes, the same cells that are are responsible for the pigmentation of zebrafish stripes and for human skin color, are also where melanoma originates.

BUSM scientists identify new biomarker and melanoma treatment target

Researchers at Boston University School of Medicine, in collaboration with Johns Hopkins University, have identified a potential new biomarker and therapeutic target for melanoma.

New personalized therapy fools cancer cells into killing themselves

A Wayne State University School of Medicine physician-researcher has developed a personalized therapy to treat a wide range of cancers. The treatment is based on a naturally occurring human enzyme that has been genetically modified to fool cancer cells into killing themselves.

New research: Reovirus infected melanoma cells secrete proteins that can kill cancer

Reoviruses are successfully being used in clinical trials to treat patients with cancer. Not only does the virus cause cancer cells to die, it also forces them to release pro-inflammatory chemokines and cytokines, which in turn causes the patient's immune system to attack the disease.

Photodynamic therapy could be useful in eradicating tumor-associated lymphatic vessels

Tumor cells have several routes that enable them to move from the primary tumor to distant tissues, a process called metastasis. It is metastasis of the primary tumor that kills most cancer patients. One of the least studied routes of metastasis is the lymphatic system. Many tumors produce factors that promote the formation of new lymphatic vessels (lymphangiogenesis).

Scientists discover that skin cancer can spread to lungs through cell blocking activity

CANCER RESEARCH UK-funded scientists have discovered that skin cancer can spread to the lungs when a gene in an important cell communication pathway is blocked. The research is published in Cancer Cell.

Researchers study relationship between MITF, ATF2 in melanoma development

Melanoma is one of the least common types of skin cancer, but it is also the most deadly. Melanocytes (pigment-producing skin cells) lose the genetic regulatory mechanisms that normally limit their number, allowing them to divide and proliferate out of control. One such regulator, called MITF, controls an array of genes that influence melanocyte development, function and survival.

Researchers discover protein that suppresses melanoma progression

In a breakthrough that could lead to new treatments for patients with malignant melanoma, researchers from Mount Sinai School of Medicine have discovered that a particular protein suppresses the progression of melanoma through regulation of an oncogene, or gene responsible for cancer growth. The study is published in the December 23 issue of Nature.

Targeting mutant BRAF can kill cancer cells, but cannot finish off melanoma

This past summer saw a revolution in melanoma therapy. Patients whose melanoma lesions contain a mutation in the BRAF gene were successfully treated with a BRAF-specific inhibitor, PLX4032. Reports of the drug trial described shrinking tumors and improved health. Yet seven months after therapy began the tumors returned and resumed growing. Now, scientists at The Wistar Institute explain why: the tumor learns to signal around the blocked gene by adjusting its molecular wiring.
