London, July 26 : In a recent study, researchers have witnessed how an enzyme works at the atomic level to repair sun-damaged DNA.
The discovery may prove to be a stepping-stone in future sunburn remedies and skin cancer prevention.
Dongping Zhong and his colleagues from Ohio State University describe how they were able to observe the enzyme, [...]
London, April 15 : It may soon be possible to prevent mitochondrial diseases, caused by mutations in the DNA of mitochondria, the energy-producing structures of the cell, from being passed on from a mother to the offspring.
British researchers have been successful in transplanting the genetic material in the nucleus of a fertilized human egg into [...]
London, April 12 : DNA damage over our lifetimes is the key reason behind the development of cancer and other age-related diseases. But not everyone gets these diseases, because the body has multiple mechanisms for repairing the damage caused to DNA by aging, the environment and other human behaviors. Now, scientists have found that a [...]
London, February 22 (ANI): Scientists have linked a region of junk DNA, the 98 per cent or so of the genome that does not code for proteins, to the risk of developing at least one form of heart disease.
The research, published online in Nature, drew on previous genome-wide association studies that linked a non-coding stretch [...]
London, Jan 11 (ANI): University of Minnesota researchers have discovered a molecular security system in human cells that deactivates and degrades foreign DNA— a feat that could pave the way to major improvements in genetic engineering and gene therapy technologies.
Led by Dr. Reuben Harris, the researchers showed how APOBEC3A, an enzyme found in human immune [...]
Toronto, Oct 8 (ANI): For the first time, scientists have decoded the entire genome of a patient’’s metastatic breast cancer-a breakthrough towards creating personalized cancer therapies using a patient’’s genetic information.
The achievement could change how people think about the way cancer develops and provides new insights into which drugs could benefit patients the most.
“I”m excited [...]
Washington, Sep 22 (ANI): Researchers at the University of Edinburgh have discovered that a protein enables sections of so-called junk DNA to be cut and pasted within genetic code- a finding which could speed up the development of gene therapies.
The study sheds light on the process, known as DNA transposition, in which shifted genes have [...]
Washington, July 3 (ANI): Scientists from Second Military Medical University in Shanghai have revealed that mutations in the DNA of hepatitis B virus (HBV) might help predict which patients are at increased risk of developing liver cancer,
HBV infection is a known cause of hepatocellular carcinoma (HCC), the most common form of liver cancer.
During the research, [...]
Washington, Feb 12 (ANI): A new study has suggested that the genome of the evolutionary ancestor of humans and present-day apes underwent a burst of activity in duplicating segments of DNA.
“The new study shows big differences in the genomes of humans and great apes within duplicated sequences containing rapidly evolving genes. Most of these differences [...]
