Cell Cycle: Regulation of DNA duplication by the mTOR signaling pathway (Houghton)

March 11, 2021

ABSTRACT Accurate and complete DNA replication and separation are essential for genetic information inheritance and organism maintenance. Errors in DNA duplication are the main source of genetic instability. Understanding DNA duplication regulation is the key to elucidate the mechanisms and find treatment strategies for human genetic disorders, especially cancer. The mechanistic target of rapamycin (mTOR) […]
