Researchers identify signaling mechanisms in pancreatic cancer cells that could provide treatment targets

Scientists have provided new insights into molecular ‚crosstalk‘ in pancreas cancer cells, identifying vulnerabilities that could provide a target for therapeutic drugs already being studied in several cancers.

The subtle difference: Pancreatic tumor organoids pave the way for single-cell diagnostics

The prognosis for pancreatic cancer is usually grim: The tumors are often detected too late and are then difficult to treat. Yet a small percentage of patients survive many years after diagnosis. Scientists from the Berlin Institute of Health at Charité (BIH) have now grown organoids from various pancreatic tumors in the laboratory, which they used to identify individual cell types and test the effects of various drugs. This enables patient-specific diagnostics and opens up the possibility of targeted therapy. The researchers have now published their findings in the journal Nature Communications.

Experimental drug boosts immunotherapy effectiveness in pancreatic cancer in mice

An experimental drug enhanced the benefit of an immunotherapy to fight pancreatic cancer in mice by increasing the number of immune cells in the immediate vicinity of the tumor, leading to a reduction in tumor growth, and in some mice, eliminating their cancer.

Scientists reverse pancreatic cancer progression in ‘time machine’ made of human cells

What makes pancreatic cancer so deadly is its covert and quick spread. Now, a ‚time machine‘ has shown a way to reverse the course of cancer before it spreads throughout the pancreas.

Lab grown tumor models could improve treatment for pancreatic cancer

An international team of scientists have created a three-dimensional (3D) pancreatic cancer tumour model in the laboratory, combining a bioengineered matrix and patient-derived cells that could be used to develop and test targeted treatments.

Link between inflammation and pancreatic cancer development uncovered

A new study finds that pancreatic cells display an adaptive response to repeated inflammation that initially protects against tissue damage but can promote tumor formation in the presence of mutant KRAS.

New drug combo shows early potential for treating pancreatic cancer

A team of researchers has developed an immunotherapy strategy that can eliminate pancreatic tumors in mice. The new therapy, a combination of three drugs that boost the body’s immune defenses against tumors, is expected to enter clinical trials later this year.

How pancreatic cancer cells dodge drug treatments

Pancreatic cancer cells typically rely on a mutant version of the KRAS protein to proliferate. These cancer cells can also survive losing KRAS by activating alternative growth pathways. Scientists discovered a new interaction between mutant KRAS and a protein complex called RSK1/NF1 that may be the source of this adaptive resistance.

PARP inhibitor shrinks tumors in pancreatic cancer patients with mutations

More than two-thirds of pancreatic cancer patients harboring genetic mutations saw their tumor stop growing or shrink substantially after being switched from intensive chemotherapy to the PARP inhibitor rucaparib as a maintenance therapy.

Immune-stimulating drug before surgery shows promise in early-stage pancreatic cancer

Giving early-stage pancreatic cancer patients a CD40 immune-stimulating drug helped jumpstart a T cell attack to the notoriously stubborn tumor microenvironment before surgery and other treatments, according to a new study.

Pancreatic cancer tumors use multiple mechanisms to avoid starvation: new target for treatment?

Researchers describe how pancreatic cancer cells use an alternative method to find necessary nutrients, defying current therapies, to help them grow and spread.

Scientists shrink pancreatic tumors by starving their cellular ’neighbors‘

Scientists have demonstrated that blocking ‚cell drinking,‘ or macropinocytosis, in the thick tissue surrounding a pancreatic tumor slowed tumor growth–providing more evidence that macropinocytosis is a driver of pancreatic cancer growth and is an important therapeutic target.

Investment needed to bring down pancreatic cancer death rates in Europe

Researchers have called on European policymakers to make adequate resources available to tackle pancreatic cancer, a disease that is almost invariably fatal and where little progress has been made over the past 40 years. The latest predictions for cancer deaths in the EU and UK for 2021 show that pancreatic death rates are predicted to remain approximately stable for men, but continue to rise in women in most EU countries.

Drug is promising against pancreatic and breast cancers

The drug is effective at treating pancreatic cancer and prolonging survival in mice, according to a new study. A second study shows the drug is also effective against triple-negative breast cancer, a fast-growing and hard-to-treat type of breast cancer that carries a poor prognosis. Clinical trials are set to begin in 2021.

Brain protein could be starting point for new treatments for pancreatic cancer

Researchers have discovered that a protein thought to only be involved in the development of neurons in the brain also plays a major role in the development and growth of pancreatic cancer. Their findings demonstrate for the first time how the protein, called Netrin-G1, helps pancreatic cancer cells survive by protecting them from the immune system and supplying them with nutrients.

Preventing pancreatic cancer metastasis by keeping cells ’sheltered in place‘

Scientists have shown that pancreatic cancer metastasis — when tumor cells gain the deadly ability to migrate to new parts of the body — can be suppressed by inhibiting a protein called Slug that regulates cell movement. The study also revealed two druggable targets that interact with Slug and hold promise as treatments that may stop the spread of pancreatic cancer.
