Oral antioxidant formulation before medical imaging may minimize cell damage

A unique formulation of antioxidants taken orally before imaging with ionizing radiation minimizes cell damage, noted researchers at the Society of Interventional Radiology's 36th Annual Scientific Meeting in Chicago, Ill.

New discovery provides insight into complex Rad50 molecular motor function

Over the last years, two teams of researchers at The Scripps Research Institute have steadily built a model of how a powerful DNA repair complex works. Now, their latest discovery provides revolutionary insights into the way the molecular motor inside the complex functions - findings they say may have implications for treatment of disorders ranging from cancer to cystic fibrosis.

Scientists identify protein that plays a key role in cancer treatment resistance

Research led by Daitoku Sakamuro, PhD, Assistant Professor of Pathology at LSU Health Sciences Center New Orleans and the LSUHSC Stanley S. Scott Cancer Center, has identified a protein that enables the activation of a DNA-repair enzyme that protects cancer cells from catastrophic damage caused by chemo and radiation therapy.

Sarsia Seed provides follow-up funding for APIM Therapeutics

APIM Therapeutics AS, an early-stage Norwegian therapeutic company, is pursuing a novel drug approach with the ability to potentiate the action of a wide range of chemotherapeutic drugs currently used to treat several types of cancer.

New lozenge clinical trial for dry mouth treatment

A clinical trial using an all-natural lozenge to treat dry mouth, a condition that impacts 40 percent of American adults, is under way at Georgia Health Sciences University College of Dental Medicine.

Human growth, height, size: Reasons to be small

Almost everybody these days thinks that it is best to be tall, meaning much taller than the average traditional height of Asian populations, and even taller than the current average height of populations in high-income countries. It is also often believed – though people might be shy to admit this – that tall people are intrinsically superior to short people. The expressions 'look up to' and 'look down on' are significant.

CRT, ICR sign deal with ZoBio to discover and develop cancer drugs

Cancer Research Technology and The Institute of Cancer Research have signed a deal with Dutch drug discovery company, ZoBio BV, to discover and develop drugs to block a DNA repair target which may play a role in cancer cell survival.

Study supports DNA mismatch repair test for bowel cancer

Bowel cancer patients whose tumors contain defects in specific DNA repair systems are much less likely to experience tumour recurrence post surgery, results from a major clinical study have demonstrated.

Study analyzes role of PARP enzyme in eukaryotes

An Ohio State University molecular biologist leveraged a supercomputer to help better define the family tree of a group of enzymes that have been implicated in a wide range of human diseases and are important targets for anti-cancer therapies.

Article outlines role of transcriptional mutagenesis in tumor development

DNA provides the instruction manual for all life forms. Occasionally, instructions are not carried out properly, and bad messages are sent leading to the creation of mutant proteins and possible tumor development.

Research: Blocking two cell DNA repair routes at once can provide new way to treat bowel cancer

Cancer Research UK-funded scientists have discovered that blocking two cell DNA repair routes at once could provide a completely new way to treat bowel cancer and potentially other cancers, according to research published in Cancer Research, today.

p53 gene blocks EMT essential to cancer metastasis

Like a bounty hunter returning escapees to custody, a cancer-fighting gene converts organ cells that change into highly mobile stem cells back to their original, stationary state, researchers report online at Nature Cell Biology.

Collision of fast and slow protein-trains cause major DNA derailment

Scientists have published results that will forever change the way researchers view the interplay between gene expression, DNA replication and the prevention of DNA damage.

Cancer-causing retrovirus prolongs survival of host cells

A cancer-causing retrovirus exploits key proteins in its host cells to extend the life of those cells, thereby prolonging its own survival and ability to spread, according to a new study by researchers at The Ohio State University Comprehensive Cancer Center - Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC - James) and Ohio State's College of Veterinary Medicine.

Metallic copper surfaces kill bacteria on contact

Metallic copper surfaces kill microbes on contact, decimating their populations, according to a paper in the February 2011 issue of the journal Applied and Environmental Microbiology. They do so literally in minutes, by causing massive membrane damage after about a minute's exposure, says the study's corresponding author, Gregor Grass of the University of Nebraska, Lincoln. This is the first study to demonstrate this mechanism of bacteriocide.

Study: Overexpression of EZH2 protein promotes breast cancer progression

An essential protein for normal stem cell renewal also promotes the growth of breast cancer stem cells when it's overproduced in those cells, researchers at The University of Texas MD Anderson Cancer Center report in the February edition of Cancer Cell.

Study: Active wound healing can lead to increased risk of basal cell carcinoma in skin

Processes that are involved in active wound healing can lead to an increased risk for basal cell carcinoma in the skin. This is the conclusion of a recent study from the Swedish medical university Karolinska Institutet, published in the journal PNAS.

Researcher discovers mechanism how p53 human genome gets inactivated in cancerous cells

One of the most important genes in the human genome is called p53 and its function is to suppress tumours, according to Roger Leng, a researcher in the Faculty of Medicine & Dentistry. Leng has discovered the mechanism by which p53 is inactivated in cancerous cells, allowing tumours to grow.

Scientists develop novel treatment strategy for multiple myeloma

Scientists at Virginia Commonwealth University Massey Cancer Center have developed a novel treatment strategy for multiple myeloma that pairs two targeted agents to kill cancer cells. The study's findings, published in today's edition of the journal "Blood," are the first to demonstrate the synergistic, anti-myeloma effects of this combination regimen both in vitro and in vivo.

Study reveals how MMSET gene enables disease-causing mutations to occur

For several decades, researchers have been linking genetic mutations to diseases ranging from cancer to developmental abnormalities. What hasn't been clear, however, is how the body's genome sustains such destructive glitches in the first place.
