Deficient DNA Repair Capacity Associated With Increased Risk Of Breast Cancer

...in vitro biomarker to identify high-risk subjects, especially in familial breast cancer families," the authors write. "It is unclear at this time whether there are any interventions that could alter DNA repair capacity and what effect such interventions might have on risk." In an editorial, Marianne Berwick, P...

Columbia research lifts major hurdle to gene therapy for cancer

...eeliminated by surgery or radiation. Gene therapy, especially forcancer, is really starting to make a comeback."The virus's selectivity for cancer cells is based on two moleculescalled PEA-3 and AP-1 that, the researchers found, are usually abundantinside cancer cells. Both of the molecules flip a switch (calle...

Genome of deadly amoeba shows surprising complexity, evidence of lateral gene transfer

...diarrhea associated with the disease can be fatal, especially in children. One field study in Bangladesh found that E. histolytica infection occurred at least once in 80 percent of 300 children. Over a period of four years, about a third of the children suffered from amebic colitis, an ulceration of the stomach...

Study Demonstrates Gene Expression Microarrays are Comparable and Reproducible

...out microarray-based experiments,reproductibility, especially inter-lab, is the #1 concern. Can I trustthese results? If I redo the same experiment in one month, will I beable to compare both? The NIH recently demonstrated that microarrays experiments performed in different labs "have a high degree of repro...

HIV Patients May Be at Risk of Heart Problems When Taking Protease Inhibitor Drugs

Weill Cornell Research Reveals Secrets Of Trafficking Within Cells

... trying to figure out what those speed limits are, especially with regard to varying amounts of clathrin," Dr. Ryan explained. However, they faced one methodological roadblock. As Dr. Ryan explained, scientists have long known how to gauge the importance of particular proteins, using a kind of Òon/offÓ compar...

First-ever Compounds To Target Only Metastatic Cells Are Highly Effective Against Breast, Prostate, And Colon Cancers

...ing right now to get a company interested in this, especially because the mice used in our trial seemed to experience minimal toxicity -- a good sign that patients might tolerate these compounds, too," Dr. Huang said. "It's all very exciting," he said. "Metastatic disease is such a tough problem, and these com...

Nano-Probes Allow an Inside Look at Cell Nuclei

... through these tiny slits, Chen and Gerion used an especially compact cadmium selenide/zinc sulfide quantum dot coated with silica. Next, they stole a trick from a virus's playbook to smuggle this nanocrystal past the highly selective membrane that guards the entrance into the nucleus. In nature, a virus called...

"One would think that if a cell became nonfunctional, it would become disorgan...

Simple drug has the potential to save many lives threatened by malaria

...The majority of fatalities occur outside hospital, especially in rural areas. For those who do make it to hospital, half of deaths occur within 24 hours of admission. Conventional treatment, given by injection, is not possible to administer outside hospital, so buying time by starting treatment which is easy t...

TEL2 gene cooperates with MYC gene to provoke B-cell lymphomas

...TEL2 should be considered a new diagnostic marker, especially in patients who don't have the classic genetic mutations that physicians normally use to diagnose the disease. It will also be very interesting to study the effect of drugs that block TEL2 activity, since such an approach might one day represent an e...
