Towards a drug to control cystic fibrosis

Harvard stem cell researchers at Massachusetts General Hospital (MGH) have taken a critical step in making possible the discovery in the relatively near future of a drug to control cystic fibrosis (CF), a fatal lung disease that claims about 500 lives each year, with 1,000 new cases diagnosed annually.

Gene mutations, age of parents and autism

New research shows that several gene mutations sharply increase the chances that a child will develop autism spectrum disorders. The researchers have found further evidence that the risk increases with the age of the parents, particularly in fathers over age 35.

Drug resistance woes hamper anti-malaria fight

Researchers have found that there is increasing resistance to the front-line treatments for malaria. A pair of studies published in The Lancet and the journal Science showed how the disease is moving fast into new territory and identified a region of the parasite's genome that may be responsible for mutating in order to survive.

New hypothesis may be a game changer in the evolution arena

A new hypothesis posed by a University of Tennessee, Knoxville, associate professor and colleagues could be a game changer in the evolution arena. The hypothesis suggests some species are surviving by discarding genes and depending on other species to play their hand.

UV light-activated on-off switch for Morpholinos

University of Oregon scientists collaborating with an Oregon company that synthesizes antisense Morpholinos for genetic research have developed a UV light-activated on-off switch for the vital gene-blocking molecule. Based on initial testing in zebra-fish embryos, the enhanced molecule promises to deliver new insights for developmental biologists and brain researchers.

Study assesses link between antifolate medications, KRAS mutations and amplification

Testing patients with non-small cell lung cancer for both mutations and amplifications of the KRAS gene prior to therapy may help to predict response to treatment with antifolates, according to the updated results of a preclinical study presented at the AACR Annual Meeting 2012, held here March 31 - April 4.

CHD8, SNC2A and KATNAL2 gene mutations lead to ASDs

Mutations in three new genes have been linked to autism, according to new studies including one with investigators at Mount Sinai School of Medicine. All three studies include lead investigators of the Autism Sequencing Consortium.

Piceatannol blocks preadipocytes’ ability to develop and grow

A compound found in red wine, grapes and other fruits, and similar in structure to resveratrol, is able to block cellular processes that allow fat cells to develop, opening a door to a potential method to control obesity, according to a Purdue University study.

Fathers more likely to transmit spontaneous mutations to children with ASDs

Researchers have turned up a new clue to the workings of a possible environmental factor in autism spectrum disorders (ASDs): fathers were four times more likely than mothers to transmit tiny, spontaneous mutations to their children with the disorders. Moreover, the number of such transmitted genetic glitches increased with paternal age. The discovery may help to explain earlier evidence linking autism risk to older fathers.

New SORL1 gene causes early-onset Alzheimer's

A new gene that causes early-onset of Alzheimer's disease has been discovered by the research team of Dominique Campion at the Insert unit 1079 "Genetics of cancer and neuropsychiatric diseases" in Rouen.

Getting pregnant while on a diet may lead to an obese baby: Study

Researchers found in a study on sheep that giving ewes less food at the time of conception caused DNA changes in the brains of their young. The University of Manchester scientists suspect the findings may hold true for humans as well and could explain why twins are more likely to develop Type 2 diabetes in adulthood.

Anti-TAK1 agents may hold hope against highly aggressive KRAS mutant colon cancers

Anurag Singh, PhD, assistant professor in the Department of Pharmacology and Experimental Therapeutics at Boston University School of Medicine has been invited to present his recent work on targeted therapeutics for colon cancer at the American Association of Cancer Research Annual Meeting in Chicago, IL.

Reactivation of p53 may be a highly selective treatment modality for virally-induced lymphoma

Kaposi's sarcoma herpesvirus (KSHV) is a human tumor virus and an etiological agent for Kaposi's sarcoma and primary effusion lymphoma (PEL). PELs are aggressive lymphomas with reported median survival time shorter than six months after diagnosis.

Drugs that target cholesterol pathway may enhance cancer-killing potential of chemotherapy drugs

Johns Hopkins investigators are testing a way to use drugs that target a cholesterol pathway to enhance the cancer-killing potential of standard chemotherapy drugs. Their tests, in mouse models of pancreatic cancer, may yield new and more effective combinations of current and possibly new anti-cancer drugs.

Scientists discover why rapamycin causes diabetic-like symptoms in patients

Scientists at Dana-Farber Cancer Institute have discovered why diabetic-like symptoms develop in some patients given rapamycin, an immune-suppressant drug that also has shown anti-cancer activity and may even slow ageing.

Scientists discover new anti-HCV antibodies

A team led by scientists at The Scripps Research Institute has found antibodies that can prevent infection from widely differing strains of hepatitis C virus (HCV) in cell culture and animal models.

Stress-induced tolerance can prevent glaucoma

Working in mice, scientists at Washington University School of Medicine in St. Louis have devised a treatment that prevents the optic nerve injury that occurs in glaucoma, a neurodegenerative disease that is a leading cause of blindness.

Researchers discover two optimal gene targets for new colorectal cancer test

A study presented today by Mayo Clinic researchers at the American Association for Cancer Research (AACR) Annual Meeting 2012 in Chicago identified two genes that are optimal targets to be analyzed in a new noninvasive test for colorectal cancer developed by Mayo Clinic, in collaboration with Exact Sciences Corporation.

Researchers figure out how rapamycin causes diabetes

The drug known as rapamycin is widely used by cancer and transplant patients, and there are hints that it might even help us put off old age and live longer. But, it also comes with a downside: rapamycin leads to diabetes in as many as 15 percent of the people who take it.

Gbb38 protein helps explain how cells send many long-haul messages

As they work together to form body parts, cells in developing organisms communicate like workers at a construction site. The discovery of a new signaling molecule in flies by Brown University biologists not only helps explain how cells send many long-haul messages, but also provides new clues for researchers who study how human development goes awry, for instance in cases of cleft lip and palate.
