UC San Diego biologists have uncovered a quality control timing mechanism tied to cell division. The “stopwatch” function keeps track of mitosis and acts as a protective measure when the process takes too long, preventing the formation of cancerous cells.

Biologists have unraveled the mystery of how chromosomes are inherited correctly every time a cell divides. They discovered how a “matchmaker” molecule stops cell division until components are ready to be split. Alterations in the process can result in birth defects and certain cancers.

Researchers at the University of California, San Diego School of Medicine have identified a protein critical to hematopoietic stem cell function and blood formation. The finding has potential as a new target for treating leukemia because cancer stem cells rely upon the same protein to regulate and sustain their growth.

When a rapidly-growing cell divides into two smaller cells, what triggers the split? Is it the size the growing cell eventually reaches? Or is the real trigger the time period over which the cell keeps growing ever larger? A novel study published online today in the journal Current Biology has…

…has discovered a new cellular mechanism that explains how cells can adapt to pressure changes during tissue growth by packing themselves into a unique shape. Researchers at UC San Diego’s Scripps Institution of Oceanography, Stanford University’s Hopkins Marine Station, and the Institute of Biomedicine in Seville (IBiS) in Spain led…

Pancreatic beta cells help maintain normal blood glucose levels by producing the hormone insulin — the master regulator of energy (glucose). Impairment and the loss of beta cells interrupts insulin production, leading to type 1 and 2 diabetes. Using single-cell RNA sequencing, researchers at University of California San Diego School…

…in the Section of Cell and Developmental Biology have “got mail”—of the cellular sort. They know that cells have elaborate “addressing” functions that “send” proteins to the correct compartment, but they are now learning how cells “’write” the addresses and then “read” them. This is important because cellular function depends…

UC San Diego scientists discover shattered chromosomal fragments are tethered together during cell division before being rearranged; destroying the tether may help prevent cancerous mutations
