Photo credit: THAVIS 3D via Unsplash. In recent days I have covered a new paper published in BioEssays by Australian molecular biologist John Mattick who cites the need for a “paradigm shift” in biology away from the concept of junk DNA (see here, here, and here). I recounted how this shift is being driven by…

The mysterious role of ancient viruses embedded in human DNA | Health
In the blueprint for life that is the human genome, there are some mysterious, silent particles. They perform no function and have gone unnoticed for thousands and thousands of years. They are species of ancestral viruses, remnants of ancient pandemics, that became embedded in the DNA of germ cells (that…
Researchers reveal key role of ASD-risk factor POGZ in control of 2C program and retrotransposon elements
Graphical abstract. Credit: Cell Reports (2023). DOI: 10.1016/j.celrep.2023.112867 A significant portion of mammalian genomes are composed of retrotransposable elements (REs). Unlike the previous hypothesis that these are “junk DNA,” recent studies have shown that REs such as endogenous retroviruses (ERVs) and long interspersed nuclear element 1 (LINE1) play essential roles…

As expected, wine grapes found to have high deleterious genetic burden
A region containing a Fer-like gene was predicted to have introgressed from the EU and under selection. (A) A cluster of the malectin/receptor-like protein kinase domain was observed around the introgressed region. The malectin domain is represented by blue boxes. The red boxes indicate the CDS of the candidate Fer-like…
SickKids scientists shine light on the complex genetics that underlie blood pressure regulation
Scientists at The Hospital for Sick Children (SickKids) are delving deep into the non-coding genome to unravel the complex genetics that underlie blood pressure regulation and hypertension (high blood pressure) – the leading cause of cardiovascular disease affecting 1.25 billion people worldwide. While the human genome comprises coding and non-coding…
Molecular Explanation For How One Woman Doesn’t Feel Pain And Heals Rapidly
Jo Cameron is a woman who doesn’t feel pain but is also spared the usual consequences, thanks to rare mutations. She also experiences less anxiety or fear than other people. A study of the molecular basis of her condition could yield medical benefits for the rest of us. Not feeling pain…
LincRNA discovery could lead to targeted treatments
Our genetic code includes more than 15,000 specific sections that can be made into molecules called lincRNAs. Some of these sections can occur in coiled-up sections of our genome called topologically associating domains, or TADs. LincRNAs derived from TADs appear to act as markers indicating the specific kind of tissue…
Keyword: ncrna
Once considered unimportant “junk DNA,” scientists have learned that non-coding RNA (ncRNA) — RNA molecules that do not translate into proteins — play a crucial role in cellular function. Mutations in ncRNA are associated with a number of conditions, such as cancer, autism, and Alzheimer’s disease. Now, through the use…
Do We Really Need All This Junk DNA? Israeli Study Says Yes
Why is ‘junk DNA’ not deleted from the original genome over millions of years of evolution? A bold new hypothesis developed by Tel Aviv University scientists offers a possible solution to the question of why neutral sequences, also known as “junk DNA,” continue to exist within the human genome for…
