Ever wondered how quickly lncRNAs can shape gene expression? ⏰ 🧬 Today, a groundbreaking study from John Rinn's laboratory and HAYA's Scientific Advisor sheds light on this question. This study reveals that the long non-coding RNA (lncRNA) Firre influences epigenetic and transcriptional states much more rapidly than previously thought —within 15 minutes of induction, and these effects can persist for days. This discovery paves the way for a deeper understanding of the temporal regulatory roles of lncRNAs in epigenetic and transcriptional states. Congratulations to the team! 🚀 Learn more: https://lnkd.in/ePzn5BFw #lncRNA #time #epigenetics #GeneRegulation

How quickly can lncRNAs influence gene expression? A recent study reveals that the lncRNA Firre can impact epigenetic and transcriptional states within just 30 minutes of induction. The research, tracked Firre-induced regulatory events from 15 minutes to four days. Surprisingly, Firre RNA triggers early regulatory events within 30 minutes, leading to significant transcriptional changes after 12 hours—earlier than seen in previous lncRNA studies. Moreover, these changes are epigenetically remembered for several days, suggesting a lasting influence on gene expression. While these findings are groundbreaking, further research is crucial to unravel the mechanisms driving these swift and enduring alterations. The implications of this study could be profound in shaping new therapeutic approaches targeting lncRNAs.

Really interesting work by scientists at Rejuvenate Bio demonstrating extended #lifespan AND #healthspan in aged male mice administered AAV-directed inducible expression of Yamanaka transcription factors to partially reprogram DNA methylation patterns associated with advanced #aging. The AAV9 system used significantly reversed #epigenetic age in #liver and #heart, but not in #brain. Notably, targeting peripheral tissues could still have measurable #antiaging impact. The comparatively transient/ inducible nature of gene manipulation implemented might have decreased likelihood of cMyc driven teratoma formation, which is a critical concern when enhancing expression of anti-aging (but #oncogenic) factors. Avoiding teratoma formation may also be a question of which tissues are targeted for partial epigenetic clock rejuvenation. It really would be cool to see how this works in aged female mice!

APOE ε4 genetics isn't destiny when it comes to Alzheimer's disease. This recent study highlights a significant finding: certain versions of the fibronectin 1 gene (FN1) may protect people with two copies of the APOE ε4 gene from the increased risk of developing Alzheimer's disease. Consider this in addition to research on the value of proactive lifestyle choices in reducing Alzheimer's risk.

Visualizing Protein Complexes on specific enhancers in Drosophila Larval nuclei - https://scft.link/2CMFI Dr. Samir Merabet and Dr. Solène Vanderperre from the University of Lyon have developed a technique called BiFOR, combining BiFC and ANCHOR DNA-labeling, to visualize protein complexes in Drosophila larval nuclei. Their research, published in Cells, uncovers the dynamics of transcription factor interactions on specific enhancers, providing insights into gene regulation. #Drosophila #GeneRegulation #ProteinComplexes #BiFOR #MolecularBiology #sciencefeatured #sciencenews
