One of the most basic and intensively studied processes in biology—one which has been detailed in biology textbooks for decades—has gained a new level of understanding, thanks to the application of simple math to a problem that scientists never before thought could benefit from mathematics.
The scientists who made the discovery, published in this week's advance online publication of Nature, found that the process bacteria use to quickly adapt to metabolize preferred energy sources such as glucose—a process called “catabolite repression”—is controlled not just by glucose, as had long been known and taught, but just as much by other essential nutrients, such as nitrogen and sulfur, available to bacteria in their growth medium.
“This is one of the most studied processes in molecular biology; it’s in every textbook,” says Terence Hwa, a professor of physics and biology at UC San Diego, who headed the team of scientists. “We showed that this process doesn’t work the way most people thought it did for the past several decades, and its purpose is different from what had generally been assumed.”
A biology and physics professor at UC San Diego has received a $1.15 million grant from the National Science Foundation to establish a series of annual “boot camps” that will educate San Diego-area high school and college students about an emerging field at the intersection of physics and biology called “quantitative biology.”
"Quantitative biology is more than adding numbers to what biologists already know,” says Suckjoon Jun, an assistant professor of physics and molecular biology, who received the five-year Faculty Early Career Development (CAREER) grant, awarded by the foundation to promising young scholar-researchers, and will work with a biology professor at San Diego State University to start the first of the boot camps next summer. “The power of the approach is to bring quantitative rigor from physical sciences to identify and solve important and interesting problems in biology.”
Two early-career scientists at UC San Diego are among 22 of the nation’s most enterprising researchers named Pew Scholars in the Biomedical Sciences by The Pew Charitable Trusts.
These scholars will each receive $240,000 over the next four years to pursue research projects without restriction that are focused on solving some of the nation’s most perplexing health problems—including diabetes, autism, Parkinson’s disease and cancer.
Andrew Huberman, an assistant professor of neurosciences, neurobiology and ophthalmology, and Suckjoon Jun, an assistant professor of physics and molecular biology, join a prestigious community of Nobel laureates, MacArthur Fellows, Albert Lasker Basic Medical Research Award winners and hundreds of other pioneers who earned Pew grants at the start of their careers.
The National Science Foundation has awarded Graduate Research Fellowships to Ph.D. students Gabriel Pratt and Kunal Bhutani in the Bioinformatics Graduate Program.
One of the newest faculty members at UC San Diego—Suckjoon Jun, an assistant professor of physics and molecular biology—has won a $1.6 million award from the Paul G. Allen Family Foundation. This is the first award given to a UC San Diego recipient from the foundation, which was established by the co-founder of Microsoft to support high-risk, high-reward ideas in science. Jun’s effort is one of five awards announced by the foundation last week to projects “that aim to unlock key questions in the areas of cellular decision making and modeling dynamic biological systems.”
The Program and everyone who knew him was saddened today by the news of the passing of Professor Virgil Woods, an innovator of mass spectrometry and structural bioinformatics, and an engaging colleague, advisor and committee member to several of the Program students.
Bioengineers at the University of California, San Diego have developed a method of modeling, simultaneously, an organism’s metabolism and its underlying gene expression. In the emerging field of systems biology, scientists model cellular behavior in order to understand how processes such as metabolism and gene expression relate to one another and bring about certain characteristics in the larger organism.
In addition to serving as a platform for investigating fundamental biological questions, this technology enables far more detailed calculations of the total cost of synthesizing many different chemicals, including biofuels. Their method accounts, in molecular detail, for the material and energy required to keep a cell growing, the research team reported in the journal Nature Communications.
“With this new method, it is now possible to perform computer simulations of systems-level molecular biology to formulate questions about fundamental life processes, the cellular impacts of genetic manipulation or to quantitatively analyze gene expression data,” said Joshua Lerman, a Ph.D. candidate in Bernhard Palsson’s Systems Biology Research Group.
Using a new assay method to study tumor cells, researchers at the University of California, San Diego School of Medicine and UC San Diego Moores Cancer Center have found evidence of clonal evolution in chronic lymphocytic leukemia (CLL). The assay method distinguishes features of leukemia cells that indicate whether the disease will be aggressive or slow-moving, a key factor in when and how patients are treated.
The findings are published in the July 26, 2012 First Edition online issue of Blood.
Coauthors include two members of the Bioinformatics program: alumnus Han-Yu Chuang, Ph.D. (lead author) and Prof. Trey Ideker.
Biologists at UC San Diego have discovered a chemical that offers a completely new and promising direction for the development of drugs to treat metabolic disorders such as type 2 diabetes—a major public health concern in the United States due to the current obesity epidemic.
Their discovery, detailed in a paper published July 13 in an advance online issue of the journal Science, initially came as a surprise because the chemical they isolated does not directly control glucose production in the liver, but instead affects the activity of a key protein that regulates the internal mechanisms of our daily night and day activities, which scientists call our circadian rhythm or biological clock.
The team was headed by Prof. Steve Kay, dean of the Division of Biological Sciences and a faculty member of the Bioinformatics and Systems Biology program.
Hemimegalencephaly is a rare but dramatic condition in which the brain grows asymmetrically, with one hemisphere becoming massively enlarged. Though frequently diagnosed in children with severe epilepsy, the cause of hemimegalencephaly is unknown and current treatment is radical: surgical removal of some or all of the diseased half of the brain.
In a paper published in the June 24, 2012 online issue of Nature Genetics, a team of doctors and scientists, led by researchers at the University of California, San Diego School of Medicine and the Howard Hughes Medical Institute, say de novo somatic mutations in a trio of genes that help regulate cell size and proliferation are likely culprits for causing hemimegalencephaly, though perhaps not the only ones.
Coauthors include two Bioinformatics and Systems Biology program members: Joseph G. Gleeson, M.D., and Vineet Bafna, Ph.D.
Strains of bacteria able to resist multiple antibiotics pose a growing threat to public health, yet the means by which resistance quickly emerges aren’t well understood. Scientists led by physics professor Terence Hwa at the University of California, San Diego, thought that the variety of environments in which bacteria encounter antibiotic drugs could play an important role. They have developed a mathematical model, published in the June 18 early online edition of the Proceedings of the National Academy of Sciences, that demonstrates how that would work.
In the June 13 issue of Science Translational Medicine, an international team led by researchers from the University of California, San Diego School of Medicine reports that the new technology of exome sequencing is not only a promising method for identifying disease-causing genes, but may also improve diagnoses and guide individual patient care.
In exome sequencing, researchers selectively and simultaneously target and map all of the portions of the genome where exons reside. Exons are short, critical sequences of DNA in genes that are translated into proteins – the biological workhorses involved in virtually every cellular function, plus various structural or mechanical duties.
The researchers, headed by principal investigator Joseph G. Gleeson, MD, professor of neurosciences and pediatrics at UC San Diego and Rady Children’s Hospital-San Diego, sequenced the exomes of 118 patients who had been diagnosed with specific neurodevelopmental diseases. In each of the cases, all known genetic causes of their disease had been previously excluded.
Five scientists from the University of California, San Diego and its School of Medicine have been awarded almost $12 million in new grants from the California Institute for Regenerative Medicine (CIRM) to conduct stem cell-based research into regenerating spinal cord injuries, repairing gene mutations that cause amyotrophic lateral sclerosis and finding new drugs to treat heart failure and Alzheimer’s disease. Awardees include two faculty members in the Bioinformatics and Systems Biology Program: Lawrence Goldstein, who is studying Alzheimer's Disease, and Gene Yeo, who is studying Lou Gehrig's disease.
The National Academy of Sciences today elected three professors at the University of California, San Diego to membership in the prestigious National Academy of Sciences, one of the highest honors bestowed on U.S. scientists and engineers. Roberto Malinow, Ruth Williams and William Young were among the 84 new members and 21 foreign associates elected to the academy today “in recognition of their distinguished and continuing achievements in original research.” Ruth Williams, a professor in the Department of Mathematics, is a member of the Graduate Program in Bioinformatics and Systems Biology.
Researchers at the University of California, San Diego, the Medical University of South Carolina, the University of Cincinnati, and American Life Science Pharmaceuticals of San Diego have validated the protease cathepsin B (CatB) as a target for improving memory deficits and reducing the pathology of Alzheimer’s disease (AD) in an animal model representative of most AD patients. The study has been published in the online edition of the Journal of Alzheimer’s Disease.
According to investigator Vivian Y. H. Hook, PhD, professor of the UCSD Skaggs School of Pharmacy and Pharmaceutical Sciences and professor of neurosciences, pharmacology and medicine at the UCSD School of Medicine, and professor in the Bioinformatics and Systems Biology Graduate Program, the study is important because it could lead to new therapeutics that improve the memory deficits of AD.
Writing in the February 17, 2012 issue of the journal Cell, researchers at the Ludwig Institute for Cancer Research, the University of California, San Diego School of Medicine and the Toronto Western Research Institute peel away some of the enduring mystery of how zygotes or fertilized eggs determine which copies of parental genes will be used or ignored.
In the Cell paper, a team of scientists, led by Bing Ren, PhD, head of the Laboratory of Gene Regulation at the Ludwig Institute for Cancer Research at UC San Diego, describe in greater detail how differential DNA methylation in the two parental genomes set the stage for selective expression of imprinted genes in the mouse. Differential DNA methylation is essential to normal development in humans and other higher organisms. It involves the addition of hydrocarbon compounds called methyls to cytosine, one of the four bases or building blocks of DNA. Such addition alters the expression of different genes, boosting or suppressing them to help direct embryonic growth and development.
Led by researchers at the University of California, San Diego School of Medicine, scientists have, for the first time, created stem cell-derived, in vitro models of sporadic and hereditary Alzheimer’s disease (AD), using induced pluripotent stem cells from patients with the much-dreaded neurodegenerative disorder.
“Creating highly purified and functional human Alzheimer’s neurons in a dish – this has never been done before,” said senior study author Lawrence Goldstein, PhD, professor in the Department of Cellular and Molecular Medicine, Howard Hughes Medical Institute Investigator and director of the UC San Diego Stem Cell Program. “It’s a first step. These aren’t perfect models. They’re proof of concept. But now we know how to make them. It requires extraordinary care and diligence, really rigorous quality controls to induce consistent behavior, but we can do it.”
The feat, published in the January 25 online edition of the journal Nature, represents a new and much-needed method for studying the causes of AD, a progressive dementia that afflicts approximately 5.4 million Americans. More importantly, the living cells provide an unprecedented tool for developing and testing drugs to treat the disorder. Coauthors include Bioinformatics faculty members Lawrence Goldstein and Kun Zhang.
In eukaryotes – the group of organisms that include humans – a key to survival is the ability of certain proteins to quickly and accurately repair genetic errors that occur when DNA is replicated to make new cells.
In a paper published in the December 23, 2011 issue of the journal Science, researchers at the Ludwig Institute for Cancer Research and the University of California, San Diego School of Medicine have solved part of the mystery of how these proteins do their job, a process called DNA mismatch repair (MMR).
Using Saccharomyces cerevisiae, or baker’s yeast, as their model organism, the researchers, led by Richard D. Kolodner, PhD, Ludwig Institute investigator and UCSD professor of medicine and cellular and molecular medicine, discovered that newly replicated DNA produces a temporary signal for 10 to 15 minutes after replication which helps identify it as new – and thus a potential subject for MMR.
In an example of life imitating art, biologists and bioengineers at UC San Diego have created a living neon sign composed of millions of bacterial cells that periodically fluoresce in unison like blinking light bulbs.
Their achievement, detailed in this week’s advance online issue of the journal Nature, involved attaching a fluorescent protein to the biological clocks of the bacteria, synchronizing the clocks of the thousands of bacteria within a colony, then synchronizing thousands of the blinking bacterial colonies to glow on and off in unison.
Coauthors include two members of the Bioionformatics and Systems Biology program: Ph.D. candidate Phillip Samayoa and Prof. Jeff Hasty.
Cells develop and thrive by turning genes on and off as needed in a precise pattern, a process known as regulated gene transcription. In a paper published in the November 9 issue of the journal Cell, researchers at the University of California, San Diego School of Medicine say this process is even more complex than previously thought, with regulated genes actually relocated to other, more conducive places in the cell nucleus.
Coauthors include Bioinformatics and Systems Biology faculty members Michael G. Rosenfeld, M.D. and Pieter C. Dorrestein, Ph.D.
Researchers have developed a new method to sequence and analyze the dark matter of life—the genomes of thousands of bacteria species previously beyond scientists’ reach, from microorganisms that produce antibiotics and biofuels to microbes living in the human body.
Scientists from UC San Diego, the J. Craig Venter Institute and Illumina Inc., published their findings in the Sept. 18 online issue of the journal Nature Biotechnology. The breakthrough will enable researchers to assemble virtually complete genomes from DNA extracted from a single bacterial cell. By contrast, traditional sequencing methods require at least a billion identical cells, grown in cultures in the lab. The study opens the door to the sequencing of bacteria that cannot be cultured—the lion’s share of bacterial species living on the planet.
The UC San Diego coauthors are computer science postdoctoral researcher Hamidreza Chitsaz; mathematics professor Glenn Tesler; and computer science professor Pavel Pevzner.
Ph.D. candidate Roger Chang and colleagues including Prof. Bernhard Palsson and alumnus Jason Papin, have reconstructed the metabolic network for the algae strain Chalydomonas einhardtii, a potential source of biofuel.

Even the merest of microbes must be able to talk, to be able to interact with its environment and with others to not just survive, but to thrive. This cellular chatter comes in the form of signaling molecules and exchanged metabolites (molecules involved in the process of metabolism or living) that can have effects far larger than the organism itself. Humans, for example, rely upon thousands of products derived from microbially produced molecules, everything from antibiotics and food supplements to ingredients used in toothpaste and paint.
Remarkably, most of what’s known about how microbes communicate with each other is the result of indirect observation and measurements. There has been no general or informative technique for observing the manifold metabolic exchange and signaling interactions between microbes, their hosts and environments. Until now. In a paper published in the May 5 online issue of the journal Angewandte Chemie, researchers at UC San Diego and Scripps Institution of Oceanography report using a new form of imaging mass spectrometry to dramatically visualize multiplex microbial interactions.
