Active ingredient in cannabis protects aging brain cells

LA JOLLA—Decades of research on medical cannabis has focused on the compounds THC and CBD in clinical applications. But less is known about the therapeutic properties of cannabinol (CBN). Now, a new study by Salk scientists shows how CBN can protect nerve cells from oxidative damage, a major pathway to cell death. The findings, published online January 6, 2022, in the journal Free Radical Biology and Medicine, suggest CBN has the potential for treating age-related neurodegenerative diseases, like Alzheimer’s.

Plants rely on the CLASSY gene family to diversify their epigenomes

LA JOLLA—What determines how a cell’s genome is regulated to ensure proper growth and development? Turns out, the parts of the genome that are turned on or off in each cell-type or tissue play a major role in this process. Now, a team at Salk has shown that the CLASSY gene family regulates which parts of the genome are turned off in a tissue-specific manner. The CLASSYs essentially control where the genome is marked by DNA methylation—the addition of methyl chemical groups to the DNA that act like tags saying, “turn off.” Because DNA methylation exists across diverse organisms, including plants and animals, this research has broad implications for both agriculture and medicine. The work, published in Nature Communications on January 11, 2022, identifies the CLSY genes as major factors underlying epigenetic diversity in plant tissues.


Salk Professor Ronald Evans awarded $1.2 million by Larry L. Hillblom Foundation to study a new druggable pathway that could help treat diabetes

LA JOLLA—Professor Ronald Evans will receive $1.2 million over four years as part of a Network Grant from the Larry L. Hillblom Foundation to examine a molecular pathway that regulates blood sugar and fat independent of insulin. The research will advance our understanding of type 2 diabetes and could lead to the development of new therapies for treating the disease. Other members of the team include Professors Jin Zhang and Alan Saltiel from the University of California San Diego.


Salk researchers find a new route for regulating blood sugar levels independent of insulin

LA JOLLA—The discovery of insulin 100 years ago opened a door that would lead to life and hope for millions of people with diabetes. Ever since then, insulin, produced in the pancreas, has been considered the primary means of treating conditions characterized by high blood sugar (glucose), such as diabetes. Now, Salk scientists have discovered a second molecule, produced in fat tissue, that, like insulin, also potently and rapidly regulates blood glucose. Their finding could lead to the development of new therapies for treating diabetes, and also lays the foundation for promising new avenues in metabolism research.

The 23 scientists chosen to lead 2021 ASPIRE projects represent disciplines across the spectrum of cancer research at top academic institutions worldwide.


Pain and anxiety impact breathing on a cellular level

LA JOLLA—You’re startled by a threatening sound, and your breath quickens; you smash your elbow and pant in pain. Why a person’s breathing rate increases dramatically when they’re hurting or anxious was not previously understood. Now, a team of Salk scientists has uncovered a neural network in the brain that coordinates breathing rhythm with feelings of pain and fear. Along with contributions to the fields of pain management, psychological theories of anxiety, and philosophical investigations into the nature of pain, their findings could lead to development of an analgesic that would prevent opioid-induced respiratory depression (OIRD), the disrupted breathing that causes overdose deaths.


Improving drug options for colorectal cancer patients

LA JOLLA—Patients with colorectal cancer were among the first to receive targeted therapies. These drugs aim to block the cancer-causing proteins that trigger out-of-control cell growth while sparing healthy tissues. But some patients are not eligible for these treatments because they have cancer-promoting mutations that are believed to cause resistance to these drugs.


Which side is which?: How the brain perceives borders

LA JOLLA—In the classic “Rubin’s vase” optical illusion, you can see either an elaborate, curvy vase or two faces, noses nearly touching. At any given moment, which scene you perceive depends on whether your brain is viewing the central vase shape to be the foreground or background of the picture.


Reading the mind of a worm

LA JOLLA—It sounds like a party trick: scientists can now look at the brain activity of a tiny worm and tell you which chemical the animal smelled a few seconds before. But the findings of a new study, led by Salk Associate Professor Sreekanth Chalasani, are more than just a novelty; they help the scientists better understand how the brain functions and integrates information.


Six Salk professors named among most highly cited researchers in the world

Long-lived proteins in mitochondria of the brain stabilize protein complexes

LA JOLLA—Mitochondria are known as the powerhouses of the cell, generating the energy that’s needed to fuel the functions that our cells carry out. Now, scientists at the Salk Institute and the University of California San Diego (UCSD) have taken a closer look at how mitochondria are maintained in nondividing cells, such as neurons, with the ultimate goal of developing a better understanding of how to prevent or treat age-related diseases. The researchers found that many of the proteins in mitochondria last much longer than expected, and that this stability likely protects them from damage. The findings were published October 28, 2021, in Developmental Cell.
