Latest Cellular processes Stories
Using yeast genetics and a novel scheme to selectively remove a single protein from the cell division process called meiosis, a cell biologist at The Florida State University found that when a key molecular player known as Pds5 goes missing, chromosomes fail to segregate and pair up properly, and birth defects such as Down syndrome can result.
As part of the intricate ballet of synaptic transmission from one neuron to the next, tiny vesicles â€“ bubbles containing the chemical neurotransmitters that make information exchange possibleâ€”travel to the tip of neurons (synapses), where they fuse with the cell's membrane (a process called exocytosis).
A process that limits the number of times a cell divides works much differently than had been thought, opening the door to potential new anticancer therapies, researchers at UT Southwestern Medical Center report in the Aug. 7 issue of the journal Cell.
Cell cycle checkpoints act like molecular tripwires for damaged cells. Leave the tripwire in place for too long, however, and cancer cells will press on regardless, making them resistant to certain types of chemotherapy, according to researchers at the Salk Institute for Biological Studies.
Success in soccer sometimes comes with "bending it like Beckham." Success in cellular fusion â€” as occurs at the moment of conception and when nerve cells exchange neurotransmitters â€” requires that a membrane be bent before the merging process can begin, University of Wisconsin-Madison researchers have shown.
The ability to specifically target and modify genes in the mouse allows researchers to use this small rodent to study how certain genes contribute to human disease. A common method used to make genetic changes in mice and cells is called site-specific recombination, where two DNA strands are exchanged.
â€œA biologist, a physicist, and a nanotechnologist walk into a ...â€ sounds like the start of a joke. Instead, it was the start of a collaboration that has helped to decipher a critical, but so far largely unstudied, phase of how cells divide.
Scientists at Dana-Farber Cancer Institute have uncovered the mechanism behind a promising new approach to cancer treatment: damaging cancer cells' DNA with potent drugs while simultaneously preventing the cells from repairing themselves.
Scientists from the Department of Biological Sciences and the Virginia Bioinformatics Institute (VBI) at Virginia Tech have developed a quantitative, mathematical model of DNA replication and cell division for the bacterium Caulobacter crescentus.
The promise of stem cell therapy may lie in uncovering how adult cells revert back into a primordial, stem cell state, whose fate is yet to be determined.
