Florida Researcher Identifies Possible Biomarker for Ovarian Cancer Screening 7/08/04
July 8, 2004 6:44 am | Articles | CommentsBy Mark Terry Ovarian cancer is usually diagnosed when the cancer has already progressed to Stage 3 or 4.

Lee Moffitt Cancer Center and Research Institute, Tampa, Fla., "the cure rate is only in the range of 25%. The problem has always been that we have no early detection strategy."

Delivery System for RNAi Gene Therapy Opens Door to the Brain 6/14/04
June 14, 2004 12:02 pm | Articles | CommentsBy Catherine Shaffer The use of gene therapy in the treatment of brain cancer is hindered by drug delivery problems. Large molecules such as monoclonal antibodies and viral vectors cannot cross the blood-brain barrier. A featured article in the June 1 issue of Clinical Cancer Research now describes the successful delivery of a nonviral RNAi gene therapy to brain tumors in mice, resulting in a significant increase in survival times.

Researchers Eye Protein Suspects in Cell Death 06/01/04
June 1, 2004 12:54 pm | Articles | CommentsBy Mark Terry Cells have a finite number of divisions, and at each division, chromosome ends, or telomeres, shorten. When the telomeres diminish to a certain length, a number of complex pathways are triggered that halt cell division. In cancer, though, this signaling pathway is disrupted, resulting in unrestrained cell growth.
Drug Resistance Gene May Be Linked to Alzheimer’s Disease Onset 5/26/04
May 26, 2004 11:58 am | Articles | Commentsby Mark Terry Researchers at the Fox Chase Cancer Center, Philadelphia, linked Alzheimer's disease (AD) to a protein that helps cancer cells resist anti-tumor drugs. The protein, ABCA2, is associated with resistance to the cancer drug estramustine. It has also been linked to myelination and nervous system development. Involved in cellular transport, ABCA2 has also been associated with cholesterol loading. A recent report suggests there may be a connection between the transport molecule and the mechanisms behind AD.
