ITALY – Role of Stem Cells in Thyroid Tumors Discovered

Stem cells could be responsible for some forms of aggressive thyroid tumors (ATC, anaplastic thyroid carcinoma). The discovery was made by a young group of biotechnologists, biologists, and doctors from the Endocrinology department of the General Hospital of the University of Palermo. In the study, published in Plos One, the researchers described a subset of tumor stem cells that were able to proliferate continuously and may be responsible for uncontrolled tumor growth. These cells are resistant to chemotherapy and explain why ATC is so highly fatal in such a short period of time. The

Professor donates stem cells to help brother fight cancer

Many of us remain close to our siblings in adulthood, seeing each other through life’s ups and downs. But for Dr. Don Hicks, director of The Center for Church Relations and Church Health at Liberty Baptist Theological Seminary, and his brother Billy, the relationship couldn’t be closer – they share the same blood and the same immune system. That’s because Don donated his stem cells to his brother last year after discovering he was Billy’s only chance at surviving leukemia.

Billy, who lives in Nashville, Tenn., with his wife and three children (two in high school and one in college),

ITALY – Here’s Why Cancer Stem Cells Are Immortal

Scientists at the FIRC (Italian Foundation for Cancer Research) Institute of Molecular Oncology of the European Institute of Oncology in Milan have revealed how to eliminate cancer stem cells, the true reason for cancer’s incurability. Researchers led by Pier Giuseppe Pelicci, Director of the Department of Experimental Oncology of the European Institute of Oncology, and Professor of general pathology at the University of Milan, have discovered how cancer stem cells become immortal.

The same oncogenes that are responsible for triggering the process of tumor formation, also impede stem cells from growing old, and allow them to maintain their

Stem Cell–Associated Proteins Can Identify Origins of Pediatric Tumors

Research has indicated that certain sarcomas come from the mesenchymal stem cells. However, expression of neural stem cells has been noted in others. Identifying and isolating mesenchymal stem cells and neural stem cells relies on finding specific proteins expressed by both types.

In this study, eight different markers representing proteins associated with these two types of stem cells were applied to the 81 tumors. Through cluster analysis, the researchers organized the data into groups showing similar patterns. Two major subgroups of pediatric sarcomas emerged

New drug combo can destroy root of breast cancer cells

Making a breakthrough in the battle against breast cancer, scientists have used a combination of drugs to target cancer stem cells that cause the disease to spread.

Current treatments kill only the surface cells in a breast tumour, but scientists now say they can destroy the root, the Mirror reported.

They hope that the findings, revealed ahead of World Cancer Day, can be used to help women with advanced and aggressive cancers. Targeting cancer stem cells takes us a step closer to better clinical options for those with the disease, said Dr Rob Clarke, of Manchester University.
