Molecular biology has something in common with kite-flying competitions. At the latter, all eyes are on the colorful, elaborate, wildly kinetic constructions darting through the sky. Nobody looks at ...
A new study finds that proteins known as linker histones control the complex coiling process that determines whether DNA will wind into long and thin chromosomes, made up of many small loops, or short ...
Antibiotics have saved millions of lives from infectious diseases and are considered one of the most important discoveries of the 20th century. However, as the use (and abuse) of antibiotics has ...
Histones are a family of basic proteins that associate with DNA in the nucleus and help condense it into chromatin. Nuclear DNA does not appear in free linear strands; it is highly condensed and ...
Injection of activated protein C (APC) is the last resort to rescue a patient with severe sepsis. Research into how APC works reveals that the drug inactivates histones (pages 1318–1321), which are ...
In our cells, 6 feet (1.8 m) of DNA gets crammed into chromosomes that fit inside a 6-µm-wide nucleus. The proteins that help pack up that genetic material are histones, which act as spools around ...
UCLA scientists have identified a new function for histones, the spool-shaped proteins that regulate gene expression and serve as anchors for strands of DNA to wrap around. The researchers discovered ...
The genetic material--DNA-- of plants and animals (within the latter humans) is stored inside the cell, and DNA packing is guaranteed by proteins called histones. Furthermore, histones play a key role ...
In the cell nucleus, histones play a crucial role packaging DNA into chromatin. Histones are however very sticky to both DNA and RNA, so to ensure they are transported to the cell nucleus after ...
Lung fibrosis is a debilitating disease affecting nearly 250,000 people in the U.S. alone with 50,000 new cases reported each year. There is currently no cure and limited available treatment options, ...
The coronavirus disease 2019 (COVID-19) is caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which is a highly virulent virus. Evidence suggests that disruption of host ...
