Epigenetic Echoes Reveal Non-Mendelian Inheritance in Mammals

A federally funded mouse study finds that about 7% of inherited epigenetic patterns do not follow Mendel’s laws, uncovering additional imprinting events, emergent inheritance patterns that can’t be traced to either parent, and a rare mammalian paramutation in Capn11. The findings suggest epigenetic marks can be transmitted and even arise across generations, potentially influencing disease risk, and were mapped using long-read sequencing across three mouse generations.

Epigenetic drift linked to brain aging in mice

A mouse study maps epigenetic changes in the aging brain, finding widespread loss of DNA methylation, activation of transposons, and chromatin remodeling that disrupts gene regulation, suggesting brain aging arises from a breakdown of epigenetic control.

Methylation Process Fully Defined by Scientists

Researchers from UNSW Sydney have fully delineated the process of methylation, a key cellular procedure involving the addition of a ‘tagging’ methyl group to proteins, DNA, and other molecules, influencing cellular behavior and protein synthesis. This landmark study proposes a nearly complete picture of the methylation system, paving the way for new inquiries into the overall system function and potential applications in areas like baking, brewing, biofuel production, and disease treatment.

Scientists Define Methylation Process in Groundbreaking Study

Researchers from UNSW Sydney have completely defined the essential cellular process known as methylation, which is a chemical reaction where a small molecule gets added to DNA, proteins, or other molecules. The study emphasizes the essential role methylation plays in the creation of proteins and how it affects how a cell behaves. The researchers have proposed a near-complete picture of this system, implying that there's very little left to be discovered. The study opens up new avenues for how we may be able to control aspects of cell growth and behavior.
