Uncovering how injury to the pancreas impacts cancer formation

LA JOLLA—Scientists at the Salk Institute and Vanderbilt University School of Medicine Basic Sciences have found that cells in the pancreas form new cell types to mitigate injury, but are then susceptible to cancerous mutations. The research, led by Salk Professor Geoffrey Wahl and Vanderbilt Assistant Professor Kathy DelGiorno, former staff scientist in the Wahl lab, was published in the journal Gastroenterology on October 22, 2021.

Location, location, location: the cell membrane facilitates RAS protein interactions

LA JOLLA—Many cancer medications fail to effectively target the most commonly mutated cancer genes in humans, called RAS. Now, Salk Professor Geoffrey Wahl and a team of scientists have uncovered details of how normal RAS interacts with mutated RAS and other proteins in living cells for the first time. The findings, published in The Proceedings of the National Academy of Sciences on May 18, 2020, could aid in the development of better RAS-targeted cancer therapeutics.

Mysterious tuft cells found to play role in pancreatitis

LA JOLLA—Persistent inflammation of the pancreas (chronic pancreatitis) is a known risk factor for developing pancreatic cancer, the third-deadliest cancer in the United States. Tuft cells—cells sensitive to chemical (chemosensory) changes typically found in the intestines and respiratory tract—had previously been discovered in the pancreas, but their function has largely remained a mystery. Now, a team of Salk scientists led by Professor Geoffrey Wahl and Staff Scientist Kathleen DelGiorno has uncovered the formation of tuft cells during pancreatitis and the surprising role of tuft cells in immunity, using mouse models of pancreatitis. The findings, published in Frontiers in Physiology on February 14, 2020, could lead to the development of new biomarkers to test for pancreatitis and pancreatic cancer.

Mapping normal breast development to better understand cancer

LA JOLLA—Breast cancer is one of the most prevalent cancers, and some forms rank among the most difficult to treat. Its various types and involvement of many different cells makes targeting such tumors difficult. Now, Salk Institute researchers 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.

A master switch controls aggressive breast cancer

LA JOLLA—A team at the Salk Institute has identified a master switch that appears to control the dynamic behavior of tumor cells that makes some aggressive cancers so difficult to treat. The gene Sox10 directly controls the growth and invasion of a significant fraction of hard-to-treat triple-negative breast cancers.

Errant gene turns cells into mobile cancer factories

LA JOLLA–A single stem cell has the potential to generate an animal made of millions of different types of cells. Some cancers contain stem-like but abnormal cells that can act like mini factories to rapidly churn out not only more copies of themselves, but also variants that are able to better survive in the challenging and changing environments to which cancers are exposed. Worse still, these stem cell-like cancers can spread to other tissues in the body, causing metastasis.

Ability to isolate and grow breast tissue stem cells could speed cancer research

LA JOLLA—By carefully controlling the levels of two proteins, researchers at the Salk Institute have discovered how to keep mammary stem cells—those that can form breast tissue—alive and functioning in the lab. The new ability to propagate mammary stem cells is allowing them to study both breast development and the formation of breast cancers.

Salk scientists use an old theory to discover new targets in the fight against breast cancer

LA JOLLA, CA—Reviving a theory first proposed in the late 1800s that the development of organs in the normal embryo and the development of cancers are related, scientists at the Salk Institute for Biological Studies have studied organ development in mice to unravel how breast cancers, and perhaps other cancers, develop in people. Their findings provide new ways to predict and personalize the diagnosis and treatment of cancer.

The genome guardian’s dimmer switch: regulating p53 is a matter of life or death

LA JOLLA, CA—Scientists at the Salk Institute for Biological Studies have found clues to the functioning of an important damage response protein in cells. The protein, p53, can cause cells to stop dividing or even to commit suicide when they show signs of DNA damage, and it is responsible for much of the tissue destruction that follows exposure to ionizing radiation or DNA-damaging drugs such as the ones commonly used for cancer therapy. The new finding shows that a short segment on p53 is needed to fine-tune the protein’s activity in blood-forming stem cells and their progeny after they incur DNA damage.

The stemness of cancer cells

LA JOLLA, CA—A close collaboration between researchers at the Salk Institute for Biological Studies and the Institute for Advanced Study found that the tumor suppressor p53, long thought of as the “Guardian of the Genome,” may do more than thwart cancer-causing mutations. It may also prevent established cancer cells from sliding toward a more aggressive, stem-like state by serving as a “Guardian against Genome Reprogramming.”

Tumor suppressor pulls double shift as reprogramming watchdog

LA JOLLA, CA—A collaborative study by researchers at the Salk Institute for Biological Studies uncovered that the tumor suppressor p53, which made its name as “guardian of the genome,” not only stops cells that could become cancerous in their tracks but also controls somatic cell reprogramming.

The two faces of Mdmx: Why some tumors don’t respond to radiation and chemotherapy

LA JOLLA, CA—A tightly controlled system of checks and balances ensures that a powerful tumor suppressor called p53 keeps a tight lid on unchecked cell growth but doesn’t wreak havoc in healthy cells. In their latest study, scientists at the Salk Institute for Biological Studies suggest just how finely tuned the system is and how little it takes to tip the balance.

New model of p53 regulation proposed that suggests novel anticancer strategy

La Jolla, CA – Genetically engineered mice convinced scientists at the Salk Institute for Biological Studies that it was time to overhaul widely held beliefs about how a powerful tumor suppressor called p53 is controlled in cells. Their new model of p53 regulation has important implications for the development of anticancer drugs.

Cancer related gene p53 not regulated as indicated by previous tissue culture research; results may be relevant to drug development

La Jolla, CA – The cellular cascade of molecular signals that instructs cells with fatally damaged DNA to self-destruct pivots on the p53 tumor suppressor gene. If p53 is inactivated, as it is in over half of all human cancers, checks and balances on cell growth fail to operate, and body cells start to accumulate mutations, which ultimately may lead to cancer. Not surprisingly, the regulation of this vital safeguard has been studied in great detail for many years but mainly in tissue culture, or in vitro, models.

Elusive chromosomal “ignition” identified by Salk scientists

La Jolla, CA – Before the engine that drives cell division goes into gear, it must receive a biological spark from its genetic machinery to set the process in motion. In the current issue of the journal Science, researchers from The Salk Institute for Biological Studies say they have identified that “ignition” point on a human chromosome. Their findings should further understanding of how cell division is normally controlled and how it might be brought back under control in cancer cells.
