This activation undermines the body's natural defense mechanism against cancer. The study suggests reconsidering the risk-benefit ratio of nicotine-based quitting aids.
A study by Emory University scientists identified the MAP kinase signaling pathway as a key player in early melanoma development. The researchers found that this pathway is abnormally activated in early melanomas, but not in precancerous moles. This finding has implications for diagnosis and treatment of melanoma.
A study published in the Journal of the National Cancer Institute found that higher levels of the molecule HDM2 are associated with a better prognosis in patients with melanoma. Patients with high levels of HDM2 lived significantly longer after treatment than those with low levels, even ten years after diagnosis.
Researchers at Cedars-Sinai Medical Center found that pituitary tumor cells express abundant PPAR-gamma, a protein receptor linked to growth and metabolism. Treatment with common diabetes drug rosiglitazone effectively shrunk tumors and reduced hormone production in mice with Cushing's syndrome.
Researchers have found that topical retinoids, such as tazarotene, may be a safer alternative for preventing skin cancer in individuals at risk. The study used mice with basal cell nevus syndrome, a genetic disorder that predisposes them to developing large numbers of basal cell carcinomas.
Researchers at CWRU have developed a new cancer treatment using dual-release kinetics, which could potentially allow for more effective and safest local drug therapy. The device is designed to work in synergy with image-guided thermal ablation and aims to reduce exposure of normal tissues to drugs while increasing the dosage to the tum...
Researchers have developed a new breast cancer therapy that combines heat therapy, chemotherapy, and fat liposomes to deliver drugs directly to tumors. The treatment has shown promising results, destroying tumors and saving patients' breasts from surgical removal.
Researchers have discovered a genetic environment behind nerve-tissue tumors that lead to cancer, specifically NF-1. The study found that tumors grow in a permissive environment but are nonexistent when the environment is restrictive, offering new hope for treatment approaches.
A University of Illinois study found that sunlight and PCB exposure enhance the development of non-melanoma skin cancer on parts of the body not directly exposed to the sun. Mice exposed to both sunlight and PCBs developed tumors, while those with only PCB exposure did not.
Researchers discovered that Nox1 enzyme generates reactive oxygen molecules that trigger angiogenesis and tumor growth. Inhibiting Nox1 activity or reducing hydrogen peroxide levels may decrease cancer cell growth and increase sensitivity to chemotherapy.
Researchers at UT Southwestern Medical Center have developed a new procedure for delivering vaccines by manipulating dendritic cells in the skin, reducing production time from 10 days to just 24 hours. This breakthrough could lead to more effective cancer treatments and broader clinical applications.
Researchers have successfully treated kidney tumors using radio frequency energy, achieving a 91% tumor ablation rate and no cancer recurrences in 9 of 11 patients. The minimally invasive procedure is less expensive, safer, and easier than surgery.
A study by UC Berkeley researchers found that a specific type of soy protein called lunasin can prevent the development of skin tumors in mice. The high dose group showed a 70% lower incidence of tumors compared to the control group, with fewer tumors per mouse and a two-week delay in appearance.
Researchers at the University of Florida have developed a new radiation-targeting system that uses advanced imaging and optic guidance techniques to precisely target tumors. The system, now commercially available, aims to minimize damage to surrounding healthy tissues and potentially improve cure rates.

A heat-sensitive liposome has been shown to triple the amount of an anti-cancer drug delivered to tumors in mice compared to other liposome-based methods. The liposome releases its cargo rapidly and effectively, increasing the functional concentration of the drug in the tumor.
Researchers found that blocking the interaction between two naturally occurring molecules restricts tumor growth and spread in mice. Inhibition of RAGE-amphoterin interaction decreased tumor cell growth, migration, and invasion without affecting angiogenesis.
Researchers at UCSF Comprehensive Cancer Center identified genetic regions that confer susceptibility and resistance to a human-like skin cancer in mice. The findings suggest that mouse studies may reveal genetic markers of susceptibility and resistance to cancer in humans, which could impact patient-specific treatment modalities.
