A study suggests that the high prevalence of autism in humans may be an evolutionary trade-off linked to genetic changes in brain cells that enhanced cognition but increased vulnerability to neurodevelopmental disorders, highlighting natural selection's role in shaping human brain traits and susceptibility.
Cold Spring Harbor Laboratory researchers have discovered that tomato and Arabidopsis thaliana plants use different regulatory systems to control the same gene, linked to genetic makeovers over 125 million years of evolution. Mutations in the CLV3 gene can dramatically increase fruit size, but the specific areas of the gene that need to be disrupted differ between the two plants, indicating divergent evolution. Understanding these genetic differences could make crop genome engineering more predictable and beneficial for farmers and plant breeders.
New research on the roundworm species C. elegans has revealed that imbalances in RNA communication between cells and from the external environment can lead to a shortened lifespan, shedding light on the genetic regulation of aging. The study, conducted by scientists from the State University of Campinas (UNICAMP) in Brazil, demonstrates that disruptions in the transfer of RNA molecules can impact the organism's lifespan, providing insights into the aging process and associated diseases. The findings contribute to a better understanding of the intertissue signaling mechanism and its role in regulating lifespan.
A recent study published in Nature Chemical Biology explores the mechanisms and importance of RNA degradation in cellular processes. The researchers highlight the role of RNA degradation in regulating gene expression and maintaining cellular homeostasis. Understanding the processes involved in RNA degradation could provide insights into genetic regulation and potential therapeutic targets for various diseases.
