Chromatin clustering may hold cancer clues Transcriptional regulators can change the way chromatin loops group together
Something like the image above is probably what comes to mind first when you hear ‘chromatin structure’. In reality, DNA spends only a small portion of time in these tightly coiled chromosomes. Most chromatin within cells lies in diffuse strands within nuclei. Mapping the locations of genes on these strands, scientists have found that chromatin containing more actively expressed genes tends to cluster together, as do chromatin strands containing inactive genes. Now, two recent papers show that these specific arrangements of chromatin may hold clues to developing targeted drugs for diseases like cancer. Read more…
