Greater rates of mitochondrial mutations discovered in children born to older mothers
The discovery of a 'maternal age effect' could be used to predict the accumulation of mitochondrial DNA mutations in maternal egg cells -- and the transmission of these mutations to children. These mutations cause more than 200 diseases and contribute to others such as diabetes, cancer, Parkinson's disease, and Alzheimer's disease.

Cushing's syndrome: LCSB researchers characterize a new tumor syndrome
Scientists at the Luxembourg Centre for Systems Biomedicine of the University of Luxembourg have published their findings that mutations in a gene known as 'ARMC5' promote the growth of benign tumors in the adrenal glands and on the meninges: ARMC5 appears to belong to the group of so-called tumor suppressor genes. It is the first time in years that scientists have characterized such a gene.

Bio-inspired 'nano-cocoons' offer targeted drug delivery against cancer cells
Biomedical engineering researchers have developed a drug delivery system consisting of nanoscale 'cocoons' made of DNA that target cancer cells and trick the cells into absorbing the cocoon before unleashing anticancer drugs.

How metastases develop in the liver
Most tumors are only fatal if the cancer cells spread in the body and form secondary tumors, known as metastases, in other organs, such as the liver. Scientists at Klinikum rechts der Isar of Technische Universität München have now shown that increased amounts of a particular protein in the liver create favorable conditions for the implantation of cancer cells and thus for the formation of metastases. The researchers have already succeeded in preventing these processes in an animal model.

New technique enables increasingly accurate PET scan to detect cancer and heart conditions
A novel technique which reduces image degradation caused by respiratory motion during a PET scan was developed in a recent study at the University of Eastern Finland. The new technique is based on bioimpedance measurement and it allows for image reconstruction at a specific phase of the patient's breathing pattern. This, in turn, makes it possible to reduce image degradation caused by motion.

An unexpected bonus
The STAT transcription factors are involved in the development of many forms of cancer. STAT3 is frequently activated in tumor cells, so drugs targeting STAT3 could be used in cancer therapy. However, STAT3 is also important in the development of the immune system. Dagmar Gotthardt and colleagues at the Vetmeduni Vienna now show that blocking STAT3 in cells of the immune system actually leads to increased anti-tumor immunity. Anti-STAT3 therapy may thus be highly promising.

LSU Health tumor registry data find Acadiana colon cancer rates among nation's highest
A special study using data from LSU Health New Orleans School of Public Health's Louisiana Tumor Registry has found that colorectal cancer incidence rates in the Louisiana Acadian parishes are among the highest in the United States. This study appears to be the first to identify a high rate of cancer in a large, regional, US founder population, raising the possibility of a genetic predisposition. Alternatively, an unidentified, robust environmental risk factor may be present.

CNIO researchers associate 2 oncogenes with the aggressiveness and incidence of leukemia in mice
Fighting oncogenes Cdk4 and Cdk6 with inhibitors that target both molecules is more effective than inhibiting them individually. These findings could have relevance in the further development of this group of drugs, which are already being tested successfully in breast cancer clinical trials.

Bowel cancer risk reduced by adopting multiple healthy behaviors
Adoption of a combination of five key healthy behaviors is associated with a reduction in the risk of developing bowel cancer. Researchers from the German Institute of Human Nutrition Potsdam-Rehbruecke quantified the impact of combined multiple healthy lifestyle behaviors on the risk of developing bowel cancer, and found that this impact is stronger in men than in women.

New computational approach finds gene that drives aggressive brain cancer

Special chromosomal structures control key genes
Scientists have long theorized that the way in which the roughly three meters of DNA in a human cell is packaged to fit within a nuclear space just six microns wide, affects gene expression. Now, Whitehead Institute researchers present the first evidence that DNA structure does indeed have such effects -- in this case finding a link between chromosome structure and the expression and repression of key genes.

Researchers find RNA molecules in urine and tissue that detect prostate cancer
Researchers at Sanford-Burnham Medical Research Institute have identified a set of RNA molecules that are detectable in tissue samples and urine of prostate cancer patients but not in normal healthy individuals. The study sets the stage for the development of more sensitive and specific noninvasive tests for prostate cancer than those currently available, which could result in fewer unnecessary prostate biopsies with less treatment-related morbidity, according to a new study in The Journal of Molecular Diagnostics.
