Long-term exposure to fine air pollutants like PM2.5 can impair metabolic health by disrupting the normal function of brown fat through complex epigenetic changes. The study identified two enzymes, HDAC9 and KDM2B, as key drivers of this process.
A Yale research team has created a computer tool called chronODE that can pinpoint when genes turn on and off during brain development. The tool may offer applications in disease modeling and basic genomic research, and could lead to future therapeutic uses.
Scientists have discovered that MYOD protein can act as a gene silencer, clearing out old 'furniture' to reset the cell's identity. This finding challenges dogma and opens up new avenues for understanding cellular reprogramming and regenerative medicine therapies.
Researchers analyzed centromeres in onion, garlic, and Welsh onion using CENH3-targeted antibody to map centromere regions. They found significant variations in size and position/mobility between species, challenging the static view of centromeres.
A new approach for understanding chromatin's 3D structure and its influence on gene regulation has been developed by scientists at Sanford Burnham Prebys. The method measures a genomic region's proximity to the isolated center of a chromatin clump, revealing that surface regions are more active than core regions.
