A parasitic amoeba that causes severe gut disease in humans protects itself from attack by biting off pieces of host cells and putting their proteins on its own surface, according to a study by microbiologists at the University of California, Davis.
When he enrolled at UC Davis, student Mackenzie Noon gravitated towards genetics. Today, he's an undergraduate researcher studying cancer at the chromosomal level in the lab of Professor Ken Kaplan, Department of Molecular and Cellular Biology.
Microtubule fibers are hollow rods made of much smaller tubulin subunits that spontaneously assemble at one end of the rod, but exactly how they do this inside the crowded environment of living cells has been a mystery. UC Davis researchers have uncovered the mechanism that puts these blocks in place, illustrated in a new animation.
During oocyte quality control, a decision is made whether each oocyte should continue and join the reserve of eggs or undergo cellular death. New research from Neil Hunter’s laboratory at UC Davis reveals the surprising way that this critical oocyte quality control process works.
With a grant from the National Science Foundation, Assistant Professor Celina Juliano will help develop genomic tools that will promote regenerative research and hopefully increase the number of researchers using Hydra as a model system.
After a long day of teaching and research, biochemists Richard McKenney and Kassandra Ori-McKenney usually find themselves on their patio discussing topics like the cytoskeleton and motor proteins. It’s shop talk for the couple, both assistant professors in the Department of Molecular and Cellular Biology.
It’s been widely reported that investigators got a break in the East Area Rapist/Golden State Killer case when they uploaded a DNA profile to a genealogy database, GEDmatch, and identified relatives of the suspect, Joseph DeAngelo. Did they get lucky, or did they have a good chance of finding him? UC Davis population biologists Graham Coop and M. D. “Doc” Edge have written a nice explainer of the science behind this search.
Mark Winey, dean of the College of Biological Sciences at UC Davis, became fascinated by science at an early age. But the draw to biology—specifically, genetics—was prompted by Winey’s younger sister Christine, who as an infant was diagnosed with an inherited metabolic disease called galactosemia.
Software inspired by speech recognition technology could help scientists understand the secret language inside cells. A machine learning algorithm called patteRNA, designed by UC Davis researchers, rapidly mines ribonucleic acid, commonly called RNA, for specific structures, providing a new method to establish links between structure, function and disease.
In a new study appearing in Developmental Cell, Ruensern Tan, a biochemistry, molecular, cellular and developmental biology graduate student, and Assistant Professor Richard McKenney, Department of Molecular and Cellular Biology, provide a new molecular model to describe the role of motor proteins in restructuring the cytoskeleton for cell division.
The Hydra, a small freshwater invertebrate, is an advantageous model organism for regenerative biologists. Named after the serpent from Greek mythology that grew two new heads for each one cut off, this tiny, jellyfish-like creature holds within its genomic code the key to biological immortality.
Melvin M. Green, distinguished professor emeritus of molecular and cellular biology, was a geneticist and member of the National Academy of Sciences. Green co-founded the historic UC Davis Genetics Department (now part of the Department of Molecular and Cellular Biology). He passed away on Tuesday, Oct. 24, 2017, at the age of 101.
UC Davis microbiologists have analyzed swabs taken by astronauts on the International Space Station – and found pretty much the same types of microbes as in a home on Earth, according to an analysis published today (Dec. 5) in the journal PeerJ.
