DNA News and Research

RSS

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).

CTI announces results from PIX301 phase 3 trial of Pixuvri for NHL

DHA prevents age-related vision loss in lab tests

An omega-3 fatty acid found in fish, known as DHA, prevented age-related vision loss in lab tests, demonstrates recently published medical research from the University of Alberta.

Gender link discovered for colorectal cancer

Researchers have identified three new colorectal cancer risk loci, including one on the X-chromosome, bringing the total number of independent loci associated with the disease to 20.

Genetic analysis on Korean mummy reveals unique HBV genotype C2 sequence

The discovery of a mummified Korean child with relatively preserved organs enabled an Israeli-South Korean scientific team to conduct a genetic analysis on a liver biopsy which revealed a unique hepatitis B virus (HBV) genotype C2 sequence common in Southeast Asia.

Researchers uncover insights into rare genetic disorders

Researchers studying rare genetic disorders have uncovered insights into those diseases in biological structures that regulate chromosomes when cells divide. Focusing on the cohesin complex, a group of proteins forming a bracelet that encircles chromosome pairs, scientists have discovered mutations that disrupt cohesin, causing a recently recognized class of diseases called cohesinopathies.

Nature Genetics publishes results from whole genome-wide study of recurrent HBV integration in HCC

The Asian Cancer Research Group (ACRG)—an independent, not-for-profit company established by Eli Lilly and Company, Merck (known as MSD outside the United States and Canada) and Pfizer Inc.—in collaboration with BGI—the world's largest genomics organization—today announced the publication of results from a whole genome-wide study of recurrent hepatitis B virus (HBV) integration in hepatocellular carcinoma (HCC) in Nature Genetics.

QCMG establishes Illumina technology as core sequencing platform

Illumina today announced that the Queensland Centre for Medical Genomics (QCMG), home of Australia's International Cancer Genomics Consortium program, has established Illumina technology as its core sequencing platform in an expanded facility.

Secreted vesicles play role in spread of cancer

Cancer researchers have known for well over a century that different tumor types spread only to specific, preferred organs. But no one has been able to determine the mechanisms of organ specific metastasis, the so-called "soil and seed" theory of 1889. New details that could help shed light on this hypothesis have been provided by a team of researchers from Weill Cornell Medical College, Memorial Sloan-Kettering Cancer Center, and their collaborators, proposing a new mechanism controlling cancer metastasis that offers fresh diagnostic and treatment potential.

Ensemble, Genentech enter macrocyclic drug discovery collaboration

Ensemble Therapeutics, a biotechnology company developing Ensemblins, a novel class of small molecule therapeutics with the power of biologics, today announced the initiation of a drug discovery collaboration with Genentech, a member of the Roche Group, to discover macrocyclic drug candidates against targets specified by Genentech.

Single test developed that detects all known strains of H5N1

The close collaboration between scientists from the Experimental Therapeutics Centre (ETC) under the Agency for Science and Technology Research (A*STAR) and clinicians from Tan Tock Seng Hospital (TTSH) has enabled the successful development of the most comprehensive and rapid H5N1 bird flu test kit available to date.

Researchers develop tentative model for diagnosis of colon cancer

Researchers from the Universidad Politécnica de Madrid's Facultad de Informática, the Universidad del País Vasco, the Gaiker Technology Centre (Biscay) and the Hospital de Cruces in Barakaldo, have developed a tentative model for the diagnosis of colon cancer based on a biomarker panel.

CDKN1C gene mutation contributes to IMAGe syndrome

A gene previously linked to too much growth in patients has now also been linked to growth restriction. Different forms of the gene can lead to very different conditions, according to research published today in the journal Nature Genetics.

UCLA geneticists identify mutation responsible for IMAGe syndrome

UCLA geneticists have identified the mutation responsible for IMAGe syndrome, a rare disorder that stunts infants' growth. The twist? The mutation occurs on the same gene that causes Beckwith-Wiedemann syndrome, which makes cells grow too fast, leading to very large children.

Scientists show how hemizygous deletion can contribute to cancer

Chromosomal deletions in DNA often involve just one of two gene copies inherited from either parent. But scientists haven't known how a deletion in one gene from one parent, called a "hemizygous" deletion, can contribute to cancer.

X-chromosome involved in development of bowel cancer

Scientists have shown for the first time that one of the sex chromosomes is involved in the development of a cancer that can afflict both genders, according to a Cancer Research UK-funded study in Nature Genetics.

Overactive BAALC gene found in people with acute leukemia

A small inherited change in DNA is largely responsible for overactivating a gene linked to poor treatment response in people with acute leukemia.

CDC report finds states spend only a fraction of tobacco funds to fight smoking

The study says states collected $244 billion from tobacco settlement payments between 1998 and 2010, and used about $8 billion of that for anti-smoking campaigns.

Nuclear radiation exposure more serious than previously believed

Recent news reports and scientific reviews warn that nuclear radiation exposure is more serious than we believed. Just recently, the UK Guardian published an article titled, "Fukushima reactor shows radiation levels much higher than thought."

Human olfactory bulb differs from that of other mammals

Research from Karolinska Institutet in Sweden shows that the human olfactory bulb - a structure in the brain that processes sensory input from the nose - differs from that of other mammals in that no new neurons are formed in this area after birth. The discovery, which is published in the scientific journal Neuron, is based on the age-determination of the cells using the carbon-14 method, and might explain why the human sense of smell is normally much worse than that of other animals.
