Cells constantly interact with each other and with the surrounding extracellular matrix through physical forces such as tension, pressure, torque, and shear stress. Over the past 50 years, biologists have increasingly come to recognize the important role biomechanics plays in the function of cellular activities such as gene expression and signaling.
Here, The Scientist reports on recently developed methods—from upgraded versions of conventional tools to newer micro- and nanotechnologies—in the proliferating tool chest of cellular mechanobiology research. Read more

A single gene is bringing researchers closer to understanding two devastating neurodegenerative diseases. Amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration (FTLD) are both neurodegenerative diseases that ravage the body and brain. ALS attacks nerve cells, which in turn weaken muscles until they waste away, and FTLD damages the brain’s temporal and frontal lobes, leading to a loss in brain function and, ultimately, personality and behavior deterioration. While the causes of ALS and FTLD are still a mystery, both diseases share a common linkage in the gene C9orf72.
Peter Sullivan, a fifth-year doctoral student in the field of biochemistry, molecular, and cell biology, is working to better understand C9orf72 and how it functions to unravel the mystery of ALS and FTLD. Read more
What is the process that allows plant and animal organs to produce different specialized cells from an original set of identical cells? In the case of small and giant cells found in the sepals – the leaf-like covering of petals in a bud – of flowering Arabidopsis plants, the answer is randomness. Read more

Sudeep Banjade, now a postdoctoral associate at Cornell University, won the ASCB Kaluza Prizes for Excellence in Graduate Research for his graduate work in Michael Rosen’s lab at the University of Texas Southwestern Medical Center where he studied the molecular mechanisms behind phase-separation of multivalent signaling proteins. He discovered that assembly of the adhesion receptor Nephrin and its cytoplasmic partners Nck and N-WASP leads to phase-separation in solution and on model membranes, which can activate this signaling system in a switch-like fashion.

An essential molecule in cells, called phosphatidic acid (PA), is at the center of a cellular biology mystery.
This lipid, or fatty molecule, is a jack-of-all-trades – based on context, it can cause cells to move, divide or commit suicide. Elevated levels of PA have also been observed in many types of cancer as well as autoimmune and neurodegenerative diseases. Read more
Between the cracks in the sidewalk sprouts a thin, green stem with fragile white flowers. It is overlooked by the masses of people who walk past it each day. Unknown to these individuals, however, is the significance of the Arabidopsisplant within the scientific community. In her lab, Prof. Adrienne Roeder, a Nancy M. and Samuel C. Fleming Term Assistant Professor at the Weill Institute for Cell and Molecular Biology, uses the Arabidopsis sepal as a model system to study the spatial and temporal development of cells. Read more
What makes flowers on a plant almost identical, or internal organs remarkably reproducible? A study of sepals in Arabidopsis plants published in the July 11 issue of the journal Developmental Cell has revealed the mystery of how such uniformity occurs. Though the research was done on sepals – the bud that holds a plant’s reproductive organs – the researchers suspect similar mechanisms apply to organ development in all organisms. The study was conducted by an interdisciplinary team led by Cornell researchers. Read more
Graduate students and postdoctoral scholars [including Aaron Joiner, Fromme Lab] gathered in Stocking Hall recently to learn about a topic that’s strikingly absent at most universities: how to become a professor. Read more

Because they have narrow bodies and no collarbones, mice are able to squeeze through holes as small as a quarter-inch in diameter. Cancer cells similarly are able to migrate through extremely tight quarters but with a major difference: The journey often comes at a price – the deformation and, in some cases, rupture of the outer lining of a cell’s nucleus.
A research group headed by Jan Lammerding, associate professor of biomedical engineering, has been studying this phenomenon in hope of using it to develop both treatment and diagnostic solutions for the millions of people who deal with cancer every day. Read more
Cells perform some moves you definitely shouldn’t try in yoga class. As immune cells hunt down invading microbes, for example, they contort themselves to fit into the narrow gaps between other cells. Read more
As the first person in her family to pursue a doctoral degree and a research career, Katherine Herleman did not know what to expect. During her first year at Cornell as an M.S./Ph.D. student in the field of geological sciences, she found herself “doing a lot of trailblazing” and relying on informal mentorship from her peers to find her way.
Aaron Joiner, a doctoral student in the field of biochemistry, molecular and cell biology, also found himself in need of peer guidance during his first year as he “struggled a lot with ‘impostor syndrome.’” Read more
Science Magazine asked young scientists to imagine that they could obtain unlimited funding for one currently unexplored scientific endeavor. What would they propose, and how would it revolutionize their field? Tommy Vo's answer was featured. Read more

There is a growing awareness among biologists that the mechanical context of a cell determines some of its function. As a result of this awareness, many biologists are now looking outside of traditional biology and starting to focus on the mechanics and physics of cells. To do this, they are forging fruitful research relationships with engineers. Nowhere is this boundary-breaking collaboration more apparent than at Cornell’s Department of Biomedical Engineering. This trend in the field of biological research has made Cornell’s Jan Lammerding a very happy man. Read more
Each cell needs to constantly remodel the landscape of its surface because the thin membrane that surrounds all cells is fragile and must be renewed to protect the cell from lysis and death. And that’s where the trouble begins.
To remove aged and damaged cell-surface proteins, the membrane-sculpting macromolecular machine creates vesicles. These vesicles function as “molecular trash bags,” which carry old and misfolded membrane proteins from the surface into internal recycling plants, where the waste is degraded and components are reused.
That’s why Shaogeng Tang – a fourth-year doctoral student in the field of biochemistry, molecular and cell biology and recent recipient of the Harry and Samuel Mann Outstanding Graduate Student Award – is studying the ways these machines assemble and function to learn how to switch them on and off.

From Yuxin Mao's lab: Phosphoinositide (PI) lipids regulate a wide variety of cellular processes, from cell signaling to cytoskeletal dynamics, by controlling the identity and properties of cellular membranes. A large number of PI kinases and phosphatases restrict the distribution of PI species and give each cellular compartment its own, distinct PI signature. When vesicles are transported from one compartment to another, therefore, their PI composition must be modified accordingly. Two papers by Hsu et al. and Nakatsu et al. reveal that the phosphatase Sac2 promotes endocytic trafficking by dephosphorylating PI(4)P (1, 2). Read more
Cornell researchers, led by Weill Institute Associate Professor Marcus Smolka, have developed a new technique to understand the actions of key proteins required for cancer cells to proliferate. The technique will help guide the development of drugs currently in clinical trials for anti-cancer treatments that inhibit this class of proteins, called kinases. Read more

Although all cells in an organism have the same DNA, cells function differently based on the genes they express. While most studies of gene expression focus on activities in the cell's nucleus, a new Cornell study finds that processes outside the nucleus -- along the membrane -- also play important roles in gene expression.
