DNA News and Research

DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

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.

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.

Researchers uncover mechanism that explains link between autoimmunity and atherosclerosis

Patients with autoimmune diseases often show a predisposition to develop "hardening of the arteries" or atherosclerosis. LMU researchers have now uncovered a mechanism that establishes a causal link between the two disorders.

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.

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.

First study to evaluate treatment based on molecular profiling of advanced pancreatic cancer

The feasibility of selecting treatment based on individual molecular characteristics was demonstrated in a first-of-its kind pancreatic cancer clinical trial reported today by the Translational Genomics Research Institute (TGen) and the Virginia G. Piper Cancer Center at Scottsdale Healthcare.

Multimarker molecular stool test for colon cancer unaffected by medication, lifestyle factors

Research on an investigational DNA methylation test for colorectal cancer demonstrated that the only clinical variable that influenced test results was age, according to results presented at the AACR Annual Meeting 2012, held here March 31 - April 4.

SFU receives NIH grant to develop effective HIV/AIDS vaccine

Jamie Scott, a Simon Fraser University professor and Canada Research Chair in molecular immunity, and three international collaborators are getting a hefty financial boost in their efforts to develop an effective HIV/AIDS vaccine.

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.

Combination of carboplatin, paclitaxel and RT3D shows promise against head and neck cancer

A naturally-occurring harmless human virus may be able to boost the effects of two standard chemotherapy drugs in some cancer patients, according to early stage trial data published in Clinical Cancer Research.

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.

Hepatitis B-infected patients with longer telomeres more likely to develop HCC

Hepatitis B-infected patients with significantly longer telomeres—the caps on the end of chromosomes that protect our genetic data— were found to have an increased risk of getting liver cancer compared to those with shorter ones, according to findings presented by researchers at Jefferson's Kimmel Cancer Center at the American Association for Cancer Research (AACR) Annual Meeting 2012.

InstantLabs receives PTM certification for Salmonella Species Food Safety Kit

InstantLabs Medical Diagnostics Corporation, developer of the portable Hunter Accelerated Real-Time PCR system, today announced that its Salmonella Species Food Safety Kit has been certified as Performance-Tested Methods (PTM) No. 031202 by the AOAC Research Institute.

NutraGene introduces first ever commercial type 2 diabetes genetic test

With the launch of the country's first ever commercial genetic test for type 2 diabetes, Indians will now have access to clinically relevant and cost effective genetic risk assessment services. NutraGene, a Delhi based genomics company that launched the tests believes that its type 2 diabetes genetic test will provide physicians an effective tool in assessing the risk of diabetes in the Indian population and will help in implementing personalized prevention and management strategies.

MMRF announces unique oncology research partnership

The Multiple Myeloma Research Foundation (MMRF) today announced a unique oncology research partnership. This multi-year agreement involves several partners including the Translational Genomics Research Institute (TGen), Spectrum Health, and the Van Andel Research Institute.

Melanoma on the rise especially amongst the young

Women under 40 are hit hardest by the escalating incidence of melanoma, according to a Mayo Clinic study published in the April issue of Mayo Clinic Proceedings, out today. Researchers examined records from a decades-long database of all patient care in Olmsted County, Minn., and looked for first-time diagnoses of melanoma in patients 18-39 from 1970 to 2009. Melanoma cases increased eightfold among women in that time and fourfold for men, the authors say. However, death rates from melanoma fell during the same period, suggesting that early interventions may be helping to save some lives, said the researchers.

CYP1B1 protein may be a potential target for intervention in head and neck cancer

Squamous cell carcinoma of the head and neck-which typically arises from thin, flat cells that line moist surfaces inside the mouth, nose and throat-is the sixth most common type of cancer worldwide, and it has a relatively low five-year survival rate and a high recurrence rate.
