DNA methylation is a type of chemical modification of DNA that can be inherited and subsequently removed without changing the original DNA sequence. As such, it is part of the epigenetic code and is also the most well characterized epigenetic mechanism.
Medulloblastoma is a rare but devastating childhood brain cancer. This cancer can spread through the spinal fluid and be deposited elsewhere in the brain or spine.
Although all cells in an organism share the same DNA sequence, their shapes, roles, and even lifespans differ drastically.
Oncotarget published "Global DNA hypermethylation pattern and unique gene expression signature in liver cancer from patients with Indigenous American ancestry" which reported that contrasting with this pattern, the age structure of HCC in Andean people displays a bimodal distribution with half of the patients developing HCC in adolescence and early adulthood.
Bisphenol F chemical (found in plastics) may cause changes in a gene that is crucial for neurological development. Researchers from the Swedish universities of Uppsala and Karlstad made this discovery.
A research team from Brazil and Portugal has identified a link between a microRNA (miRNA) and the presence of lead in an organism.
Using a widely known field of mathematics designed mainly to study how digital and other forms of information are measured, stored and shared, scientists at Johns Hopkins Medicine and Johns Hopkins Kimmel Cancer Center say they have uncovered a likely key genetic culprit in the development of acute lymphoblastic leukemia (ALL).
Scientists have figured out how to modify CRISPR's basic architecture to extend its reach beyond the genome and into what's known as the epigenome -- proteins and small molecules that latch onto DNA and control when and where genes are switched on or off.
According to a recent study, sufficient rest during vacation time restored functions linked to DNA regulation in shift workers deprived of sleep.
Deep Longevity, a firm that specializes in designing artificial intelligence (AI) to monitor human aging and prolong productive longevity, has launched the first AI-powered psychological aging clocks to inspect and decode the psychosocial factors with respect to aging.
It's a fact of life that things break down. And when they do, whether it's your car, the roof, or a blocked artery, there are people who we can call to help with the repairs.
Many environmental and lifestyle factors have been implicated in the decline of sperm quality, with diet being one of the most plausible factors identified in recent years.
According to a new study, obese, pregnant women could decrease the health risks of their infants via better diet and increased physical activity.
A new mobile app has made it possible to analyse the genome of the SARS-CoV-2 virus on a smartphone in less than half an hour.
Some of the genetic differences that have arisen between domesticated chickens and their wild ancestors, the red junglefowl, are linked to epigenetic changes, according to a new study published in Nature Ecology & Evolution.
A study has demonstrated that epigenetic defects in the human genome are common and occur in an unlimited number of genes that lead to genetic disorders.
Scientists can detect changes in the islets of Langerhans of the pancreas in patients several years before these individuals are diagnosed with type 2 diabetes.
According to a study, headed by a psychologist at the University of California, genetic background may influence how people adapt to aging in late life.
Researchers performed a study in which they created a total of 168 new maps of chemical marks on DNA strands, known as methylation, in developing mice.
UMass Medical School researchers Zhiping Weng, PhD, and Jill Moore, PhD, and MD/PhD students Michael Purcaro and Henry Pratt are lead authors on the latest publication of data from the ambitious ENCODE project.
All life depends on a genome, which acts as an instruction manual for building all the products essential for development and survival. But knowing which of these individual instructions - or genes - need to be read, and when, is key for a properly functioning organism: so how does life get this right?
