Salk scientists develop new tools to better understand development and regeneration
|
|
In a pair of studies, the lab of Professor
Juan Carlos Izpisua Belmonte
has advanced technologies to study critical stages of embryonic development.
In the first paper, in the journal
Cell
, his team reported developing
early-stage
structures termed “blastoids,” from a single cultured mouse cell, circumventing the need for natural embryos in research. These structures could help advance discoveries in development, pregnancy, infertility or health problems later in the offspring’s life.
|
|
In a second advance published in
Science
, the team, along with collaborators in China, created a
method to allow primate embryos to grow in the laboratory longer than ever before, enabling the researchers to observe key processes of development for the first time. This technique could help inform approaches for regenerative medicine for humans.

Breast cancer is one of the most prevalent cancers, and some forms rank among the most difficult to treat. Professor
Geoffrey Wahl and colleagues have used a state-of-the-art technology to profile each cell during normal breast development in order to understand what goes wrong in cancer. The team’s findings, published in
Cell Reports, and shared in a free online resource, lay the groundwork for understanding normal breast development.

Salk scientists find way to quantify how well cutting-edge microscopy technique works

In 2017, the lab of Assistant Professor
Dmitry Lyumkis reported that tilting a frozen protein sample as it sat under an electron microscope was an effective approach to acquiring better information about its structure and helping researchers understand a host of diseases ranging from HIV to cancer. Now, they have developed a mathematical framework that underlies some of those initial observations.
Their new study, published in
Progress in Biophysics and Molecular Biology, provides a foundation for determining how differences in viewing angles affect the resulting 3D structures of proteins, and could help other researchers determine the best setup for experiments to improve the imaging technique called cryo-EM.

Novel technique helps explain why bright light keeps us awake
|
|
|
In recent decades, scientists have learned a great deal about how different neurons connect and send signals to each other. But it’s been difficult to trace the activity of individual nerve fibers known as axons, some of which can extend from the tip of the toe to the head. Professor
Satchidananda Panda and researchers from UC San Diego report a novel technique for tracing these connections and determining how neurons communicate. The team used this technique to uncover details about how the brain responds to light signals received by the retina in mice, as detailed in
Cell Reports.

Machine learning helps plant science turn over a new leaf

Gregor Mendel
, often called the “father of modern genetics”
spent years tediously observing and measuring pea plant traits by hand in the 1800s to uncover the basics of genetic inheritance. Associate Professor
Saket Navlakha and colleagues have helped speed up plant phenotyping with machine-learning algorithms that teach a computer system to analyze three-dimensional shapes of the branches and leaves of a plant. The study, published in
Plant Physiology, may help scientists better quantify how plants respond to climate change, genetic mutations or other factors.

As the tools to study biology improve, researchers are beginning to uncover details into microproteins, small components that appear to be key to some cellular processes. Professor
Alan Saghatelian, Staff Scientist
Uri Manor, director of the
Waitt Advanced Biophotonics Core Facility, and others recently showed that the 54-amino acid microprotein PIGBOS contributes to mitigating cell stress. The work, published in the journal
Nature Communications, indicates that PIGBOS could be a target for human disease.

A team of Salk scientists led by Professor
Martyn Goulding and including Professor
Samuel Pfaff, Professor
Tatyana Sharpee, Associate Professor
Axel Nimmerjahn, and Assistant Professor
Eiman Azim has been awarded $14.3 million over five years by the National Institutes of Health (NIH) to create a high-resolution atlas of how the mouse brain generates and controls skilled forelimb movements, such as reaching and grasping.

Associate Professor
Nicola Allen, Assistant Professor
Eiman Azim, Research Professor
Margarita Behrens, and Professor
Joseph Ecker have been awarded grants totaling $12.9 million by the National Institutes of Health (NIH)
BRAIN Initiative as part of its mission “to deepen understanding of the inner workings of the human mind and to improve how we treat, prevent, and cure disorders of the brain.”

Martyn Goulding receives National Institute of Neurological Disorders and Stroke
Outstanding Investigator Award
|
|
Professor
Martyn Goulding
will receive $9.5 million dollars over the next eight years to further his pioneering studies on sensorimotor circuits in the spinal cord that are important for touch, itch and pain as part of a National Institute of Neurological Disorders and Stroke Outstanding Investigator Award. Goulding, who holds the Frederick W. and Joanna J. Mitchell Chair, has shown that these circuits are important for locomotion and balance.

Tony Hunter receives National Cancer Institute Outstanding Investigator Award
|
|
Professor
Tony Hunter
has received a National Cancer Institute Outstanding Investigator Award, which supports accomplished leaders in cancer research. Hunter, who is an American Cancer Society Professor and the Renato Dulbecco Chair, will receive more than $7.5 million over the next seven years to further his work. Hunter is known for discovering tyrosine phosphorylation,
a finding that led to a new class of cancer drugs.

Salk Institute hits play on new podcast series
|
|
Salk has launched a new podcast series called
Where Cures Begin
, which explores the lives of scientists and discoveries at the Institute. Season 1 of
Where Cures Begin
features one-on-one conversations with Salk researchers working at the forefront of cutting-edge science, from cancer and neuroscience to plant biology, circadian science and more. The eight episodes of season 1 are released weekly. The first episode is available and features Assistant Professor
Eiman Azim
, who speaks about neuroscience, his life as a new dad, and the importance of training the next generation of scientists.
