A new research paper was published in Aging (Aging-US) on January 3, 2025, in Volume 17, Issue 1, titled "Characterization of DNA methylation clock algorithms applied to diverse tissue types.

“DNA methylation, the process by which methyl groups are added to DNA, plays a central role in gene expression and disease development,” explains Zhang. “Errors in methylation can trigger diseases, ...

They also discovered that another genetic process, called RNA-directed DNA methylation (RdDM), became more active over time. This process appears to influence chemical switches in the DNA that help ...

Children's exposure to tobacco smoke at home can alter their DNA and increase health risks later in life, according to a recent study led by the Barcelona Institute for Global Health (ISGlobal ...

However, it is important to note that genetic variations are not always harmful, they also help us understand how genes function in our bodies and influence traits such as height, metabolism ...

Methylation can, in turn, influence where DNA mutations appear. If a methyl group attaches at a particular part of the C, this can spark a chemical reaction that destabilizes the C, making it more ...

DNA (deoxyribonucleic acid) is the nucleic acid polymer that forms the genetic code for a cell or virus. Most DNA molecules consist of two polymers (double-stranded) of four nucleotides that each ...

If the coordination of DNA and RNA epigenetics gets thrown off, you may end up with too much or too little of a protein, Fuk suggested. "Now, a key protein will be expressed at a too high level ...

It seeks to understand the process of trait inheritance from parents to offspring, including the molecular structure and function of genes, gene behaviour in the context of a cell or organism (e.g ...

Feb. 11, 2025 — Scientists have discovered that some tiny segments of RNA thought to be junk instead have a functional role in suppressing production of certain messenger RNAs and appear to help ...
