Human Cancer Tumors Replicated In Mice And Then Cured
2013-03-06 09:23:12

April Flowers for redOrbit.com - Your Universe Online A group of scientists led by UT Southwestern Medical Center has reported the first successful blocking of tumor development in a genetic mouse model of an incurable human cancer. "To my knowledge, this is the first time that a mouse model of a genetically defined malignant human cancer has been generated in which the formation of the tumor from beginning to end can be monitored and in which blocking the pathway cures the mouse of the...

UT MD Anderson scientists find common vaccine ingredient diverts T cells from tumors Cancer vaccines that attempt to stimulate an immune system assault fail because the killer T cells aimed at tumors instead find the vaccination site a more inviting target, scientists at The University of Texas MD Anderson Cancer Center report in Nature Medicine. A common substance used in many cancer vaccines to boost immune attack betrays the cause by facilitating a buildup of T cells at the...

ICREA professor Raul Mendez publishes a study in Nature describing how the CPBE1 protein 'takes the brakes off' the production of proteins associated with the cell switch from being healthy to tumorous Cancer is characterized by uncontrolled cell division and growth. In order to identify new therapeutic targets through which to tackle the disease, scientists seek to clarify the mechanisms that control the expression of genes that favor the development of tumors, in processes such as...

Emerging Cancer Drugs May Cause Bone Tumors To Spread
2013-02-13 16:49:20

Washington University in St. Louis Cancer drugs should kill tumors, not encourage their spread. But new evidence suggests that an otherwise promising class of drugs may actually increase the risk of tumors spreading to bone, according to researchers at Washington University School of Medicine in St. Louis. The drugs, IAP antagonists, block survival signals that many cancer cells rely on to stay alive. Working in mice, the investigators found that targeting the same protein that makes...

A lack of the protein endoglin in the blood vessels of tumor-bearing mice enables the spread of daughter tumors, according to researchers at Karolinska Institutet and Lund University in Sweden in a study published in the scientific periodical The Journal of Experimental Medicine. Given that the tumor vasculature constitutes an important barrier to the spread of cancer cells, the team suggests that drugs should be developed to strengthen the blood vessels' protective function. Studies of...

A Traffic Cop For Stopping Cancer Cells?
2013-01-15 05:53:23

Connie K. Ho for redOrbit.com — Your Universe Online Researchers from the Fox Chase Cancer Center recently discovered a novel method of improving cancer drugs, where they could block a specific pathway in the cell and provide an easier way for drugs to eliminate tumors. According to the American Cancer Society, cancer occurs when there is uncontrolled growth and expansion of abnormal cells. It is caused by external factors (such as chemicals, infectious organisms, radiation, and...
