New nationwide effort seeks to find novel approaches to treat ASD, intellectual disability

Some of the genetic diseases that can cause autism spectrum disorder (ASD) and intellectual disability (ID) are so rare that even physicians who specialize in treating them can't be certain they have seen every possible symptom.

UT Southwestern researchers find new potential target for halting tumor growth

UT Southwestern Medical Center researchers have discovered that brain tumors are capable of burning acetate for fuel, providing a new potential target for halting tumor growth.

Gene variations predispose mestizo Mexican population to develop severe form of COPD

A study by Ramcés Falfán-Valencia, researcher at the National Institute of Respiratory Diseases, found that the mestizo Mexican population has a number of variations in certain genes that predispose them to develop the most severe form of chronic obstructive pulmonary disease (COPD).

Study reveals why older people are at increased risk for developing cancer

Why are older people at higher risk for developing cancer? Prevailing opinion holds that, over time, your body's cells accumulate DNA damage and that eventually this damage catches up with the body in a way that causes cancer.

Endogenous retroviruses also play critical role in the body's immune defense against pathogens

Retroviruses are best known for causing contagious scourges such as AIDS, or more sporadically, cancer.

Scientists develop new system for studying how proteins, other biological molecules unfold and refold

Collaborating scientists from The Scripps Research Institute and the University of California San Diego have developed a powerful new system for studying how proteins and other biological molecules form and lose their natural folded structures.

TUM researchers discover new mechanism for regulating programmed cell death

Programmed cell death is a mechanism that causes defective and potentially harmful cells to destroy themselves. It serves a number of purposes in the body, including the prevention of malignant tumor growth. Now, researchers at Technische Universität München have discovered a previously unknown mechanism for regulating programmed cell death.

Researchers treat myocardial infarction with new telomerase-based gene therapy

The enzyme telomerase repairs cell damage produced by ageing, and has been used successfully in therapies to lengthen the life of mice. Now it has been observed that it could also be used to cure illnesses related to the ageing process.

Even men undergo hormonal changes on way to fatherhood, study finds

Impending fatherhood can lower two hormones--testosterone and estradiol--for men, even before their babies are born, a new University of Michigan study found.

Penn, UGA scientists awarded new contract to develop genome database for microbial pathogens

At the turn of the millennium, the cost to sequence a single human genome exceeded $50 million, and the process took a decade to complete. Microbes have genomes, too, and the first reference genome for a malaria parasite was completed in 2002 at a cost of roughly $15 million. But today researchers can sequence a genome in a single afternoon for just a few thousand dollars. Related technologies make it possible to capture information about all genes in the genome, in all tissues, from multiple individuals.

Brandeis University researchers capture highest resolution images of cilia ever

Cilia, the cell's tails and antennas, are among the most important biological structures. They line our windpipe and sweep away all the junk we inhale; they help us see, smell and reproduce. When a mutation disrupts the function or structure of cilia, the effects on the human body are devastating and sometimes lethal.

U-M researchers devise reliable way to grow tumor cells

In a development that could lead to a deeper understanding of cancer and better early-stage treatment of the disease, University of Michigan researchers have devised a reliable way to grow a certain type of cancer cells from patients outside the body for study.

Researchers find link between ferrets and humans

Research that provides a new understanding as to why ferrets are similar to humans is set to have major implications for the development of novel drugs and treatment strategies.

Trophoblasts respond to inflammatory danger signals, find NTNU researchers

Trophoblasts, cells that form an outer layer around a fertilized egg and develop into the major part of the placenta, have now been shown to respond to inflammatory danger signals, researchers from Norwegian University of Science and Technology found in a recent study published in Journal of Reproductive Immunology December 2014.

Researchers reveal common features responsible for antibiotic resistance

Treating bacterial infections with antibiotics is becoming increasingly difficult as bacteria develop resistance not only to the antibiotics being used against them, but also to ones they have never encountered before. By analyzing genetic and phenotypic changes in antibiotic-resistant strains of E. coli, researchers at the RIKEN Quantitative Biology Center in Japan have revealed a common set of features that appear to be responsible for the development of resistance to several types of antibiotics.

Broccoli can help reduce HGPS-related defects

Children who suffer from Hutchinson-Gilford Progeria syndrome age prematurely due to a defective protein in their cells. Scientists at Technische Universität München have now identified another important pathological factor: the system responsible for removing cellular debris and for breaking down defective proteins operates at lower levels in HGPS cells than in normal cells. The researchers have succeeded in reactivating protein breakdown in HGPS cells and thus reducing disease-related defects by using a substance from broccoli.

Researchers examine why Mexican-Americans at increased risk for Type 2 diabetes

While people of Mexican ancestry are nearly twice as likely to develop Type 2 diabetes as people of European heritage, the majority of research in this area has focused on those of European origin.

Two orphan receptor proteins exert fatal double whammy effect against glioblastoma cells

Two related proteins exert a lethal double whammy effect against glioblastoma cells when activated with a small molecule, say researchers at Georgetown Lombardi Comprehensive Cancer Center.

Eight researchers to receive 2015 Leibniz Prize

The new recipients of Germany's most prestigious research funding prize have been announced. In Bonn today, the Joint Committee of the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) decided to award the 2015 Leibniz Prize to eight researchers.

Study offers insights into mechanisms of bacterial resistance to antimicrobial peptides

Antimicrobial peptides are a distinctive class of potent, broad-spectrum antibiotics produced by the body's innate immune system--the first line of defense against disease-causing microbes.
