ATM tumor-suppressor also recognizes damage caused by ROS and orders autophagy

ATM, a protein that reacts to DNA damage by ordering repairs or the suicide of the defective cell, plays a similar, previously unknown role in response to oxidative damage outside of the nucleus, researchers report this week in the online version of the Proceedings of the National Academy of Sciences.

Roche Molecular Systems, Merck Sharp & Dohme announce cancer therapeutics collaboration

Roche Molecular Systems, Inc. announced today a research collaboration with Merck Sharp & Dohme Corp. (a subsidiary of Merck & Co., Inc.) providing Merck access to Roche's developmental microarray-based AmpliChip p53 Test, which is designed to detect mutations in the tumor suppressor gene p53. By identifying cancers that harbor a dysfunctional p53 gene, the companies aim to achieve better treatment outcomes in cancer patients by determining which patients are most likely to respond to certain investigational therapeutic candidates.

Researchers discover new strategy to overcome drug resistance in breast cancer

Combining tamoxifen, the world's most prescribed breast cancer agent, with a compound found in the flowering plant feverfew may prevent initial or future resistance to the drug, say researchers at Georgetown Lombardi Comprehensive Cancer Center.

Researchers adopt new technique to inhibit cancer growth

One of the difficulties of fighting cancer is that drugs often hit other non-cancerous cells, causing patients to get sick. But what if researchers could sneak cancer-fighting particles into just the cancer cells?

Researchers identify potential therapeutic targets for treatment of neuroblastoma

A team of researchers, led by Patrick Mehlen, at Universit- de Lyon, France, has identified the protein NT-3 and the cell-surface molecule to which it binds (TrkC) as potential therapeutic targets for the treatment of neuroblastoma - the most frequent solid tumor in young children- by studying human neuroblastoma cells in vitro and after xenotransplantation into mice and chicks.

Stem cells intentionally cut and then repair their own DNA to develop new tissues

A new study from the Ottawa Hospital Research Institute (OHRI) and the University of Ottawa suggests that stem cells intentionally break their own DNA as a way of regulating tissue development. The study, published in Proceedings of the National Academy of Science (PNAS), could dramatically change how researchers think about tissue development, stem cells and cancer.

Muscle-preserving therapy development may help young men keep muscle shirts a bit longer

Hey guys, remember the muscle shirts we wore in our teens and 20s? After the age of 40 that meager part of our wardrobes usually is obsolete. Yes, at the big 4-0 we begin to lose muscle, and by age 80 up to a third of it may be gone. It's an inevitable process of aging called sarcopenia.

New screening system developed to discover molecules that block HCV life cycle

A newly designed system of identifying molecules for treating hepatitis C should enable scientists to discover novel and effective therapies for the dangerous and difficult-to-cure disease of the liver, says Zhilei Chen, a Texas A&M University assistant professor of chemical engineering who helped develop the screening system.

hESC and iPSC: Long-term stem cell evaluation and comparison study

For the first time, scientists have performed a detailed long-term evaluation and comparison of two different types of pluripotent stem cells: human embryonic stem cells (hESC) and induced pluripotency stem cells (iPSC). Both cell types are believed to share equal characteristics, abilities and potential to differentiate into nearly 220 different cell types. However, hESC are isolated from early human embryos and iPSC are derived from reprogrammed adult somatic cells which makes them less controversial.

Study may pave way for more refined treatments for brain tumors

Researchers at Washington University School of Medicine in St. Louis have shown once again that "ready, fire, aim," nonsensical though it may sound, can be an essential approach to research.

Thymosin β4 exhibits potential as new therapeutic agent for liver failure due to chronic HBV infection

REGENERX BIOPHARMACEUTICALS, INC. announced today that researchers have correlated Tβ4 levels with the clinical course of patients with hepatitis B virus-related liver failure. It was reported that serum thymosin β4 levels were significantly lower in patients with chronic hepatitis B infection and that the magnitude of the reduction of thymosin β4 was closely related to the severity of the hepatic injury and to patient death. Since patients with higher Tβ4 levels survived the disease, changes in Tβ4 values could reflect outcome in some liver failure patients.
