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).

Silibinin kills skin cells mutated by UVA radiation and protects against cancer

A pair of University of Colorado Cancer Center studies published this month show that the milk thistle extract, silibinin, kills skin cells mutated by UVA radiation and protects against damage by UVB radiation - thus protecting against UV-induced skin cancer and photo-aging.

Clarient adopts QIAGEN’s therascreen KRAS test to diagnose colorectal cancer

QIAGEN N.V. today announced that Clarient - a GE Healthcare Company and leading provider of cancer laboratory testing services in the United States - has adopted the use of the therascreen KRAS RGQ PCR Kit (therascreen KRAS test) as a companion diagnostic to guide the use of Erbitux (cetuximab) as a treatment in patients with metastatic colorectal cancer.

FBH1 gene helps turn up the effect of chemotherapy

Chemotherapy is one of the most common treatments for cancer patients. However, many patients suffer from serious side-effects and a large proportion does not respond to the treatment. Researchers from the Biotech Research and Innovation Centre (BRIC) and Center for Healthy Aging, University of Copenhagen, now show that the gene FBH1 helps turn up the effect of chemotherapy.

Non-coding RNA essential for normal embryonic cardiogenesis

Many different tissues and organs form from pluripotent stem cells during embryonic development. To date it had been known that these processes are controlled by transcription factors for specific tissues. Scientists from the Max Planck Institute for Molecular Genetics in Berlin, in collaboration with colleagues at MIT and the Broad Institute in Boston, have now been able to demonstrate that RNA molecules, which do not act as templates for protein synthesis, participate in these processes as well.

Human Brain Project to link basic research with disease treatment

King's College London is part of an international consortium of scientists who have today been awarded a grant of over one billion euros, over ten years, to simulate 'everything we know about the human brain' in supercomputers.

Genzyme receives FDA approval for Kynamro to treat homozygous familial hypercholesterolemia

The U.S. Food and Drug Administration today approved Kynamro (mipomersen sodium) injection as an addition to lipid-lowering medications and diet to treat patients with a rare type of high cholesterol called homozygous familial hypercholesterolemia (HoFH).

One-step, off-the-shelf tool can help evaluate genetic cause of mitochondrial diseases

More powerful gene-sequencing tools have increasingly been uncovering disease secrets in DNA within the cell nucleus. Now a research team is expanding those rapid next-generation sequencing tests to analyze a separate source of DNA—within the genes inside mitochondria, cellular power plants that, when abnormal, contribute to complex, multisystem diseases.

Scientists identify genetic process in which normal liver cells transform into cancerous ones

A team of scientists from the Cancer Science Institute of Singapore (CSI) at the National University of Singapore (NUS) has identified a genetic process in which normal liver cells transform into cancerous ones. The finding provides new understanding into the pathogenesis of human cancers.

Oncolytics Biotech reports new findings at ASCO’s 2013 Gastrointestinal Cancers Symposium

What did Pope John Paul II, Ronald Reagan and Robin Gibb of the Bee Gees have in common? Each was diagnosed with colorectal cancer, the third most commonly diagnosed cancer in the world and the fourth most common cause of cancer death.

Scientists discover four processes by which gastric cancer is formed

Scientists at A*STAR's Genome Institute of Singapore (GIS) headed a study that discovered four processes by which gastric cancer is formed. This is extremely important since gastric cancer is the second most common cause of cancer deaths worldwide, claiming almost 750,000 lives annually, 60% of which are Asians.

KLF8 protein could be helpful in preventing cancer recurrence

Just as the body can become resistant to antibiotics, certain methods of killing cancer tumors can end up creating resistant tumor cells. But a University of Central Florida professor has found a protein present in several types of cancer, including breast and ovarian cancer, which could be helpful in preventing tumors from coming back.

Mutated Nesprin4 protein prevents hearing

Because half of all instances of hearing loss are linked to genetic mutations, advanced gene research is an invaluable tool for uncovering causes of deafness - and one of the biggest hopes for the development of new therapies. Now Prof. Karen Avraham of the Sackler Faculty of Medicine at Tel Aviv University has discovered a significant mutation in a LINC family protein - part of the cells of the inner ear - that could lead to new treatments for hearing disorders.

New DNA-delivering film holds promise for improving effectiveness of vaccines

Vaccines usually consist of inactivated viruses that prompt the immune system to remember the invader and launch a strong defense if it later encounters the real thing. However, this approach can be too risky with certain viruses, including HIV.
