DNA Repair: Keeping It Together
A protein scaffold has been identified that holds a chromosome together in the event of a DNA double-strand break. This scaffold is dependent on Rad52 and the Rad50-Mre11-Xrs2 complex and withstands the pulling forces of the mitotic spindle during DNA damage checkpoint arrest.
متن کاملKeeping it together: work-life balance.
It’s typical that new dentists have put the rest of their lives on “hold” for what feels like a long time. It’s called deferred gratification, and it gets old. Friends from college have been making real money while you’ve been in school. They’re buying their second houses when you’re still paying rent; maybe they have puppies or babies. Their college loans are nothing like your dental school de...
متن کاملKeeping it all together: auxin-actin crosstalk in plant development.
Polar auxin transport and the action of the actin cytoskeleton are tightly interconnected, which is documented by the finding that auxin transporters reach their final destination by active movement of secretory vesicles along F-actin tracks. Moreover, auxin transporter polarity and flexibility is thought to depend on transporter cycling that requires endocytosis and exocytosis of vesicles. In ...
متن کاملKeeping it together: mechanisms of intersegmental coordination for a flexible locomotor behavior.
The coordination of multiple neural oscillators is key for the generation of productive locomotor movements. In the medicinal leech, we determined that activation and coordination of the segmental crawl oscillators, or unit burst generators, are dependent on signals descending from the cephalic ganglion. In nearly intact animals, removing descending input (reversibly with a sucrose block) preve...
متن کاملAbsorption from the Pulmonary Alveoli
Experiments upon dogs anesthetized with nembutal and lasting 4 hours, in which the right lymphatic duct and thoracic duct have been cannulated and collection of lung lymph and blood specimens was accomplished after intratracheal instillation of dog plasma, purified bovine serum albumin, crystallized egg albumin, and hemoglobin, have shown that the absorption of such molecules is slight. Experim...
