Stopping the cancer cells that thrive on chemotherapy – research into how pancreatic tumors adapt to stress could lead to a new treatment approach

Some cancers are notoriously resistant to chemotherapy and not curable with surgery. Stopping tumors from adapting to the harsh microenvironments of the body could be a potential treatment avenue.

Anti-cancer CAR-T therapy reengineers T cells to kill tumors – and researchers are expanding the limited types of cancer it can target

Immunotherapy has the potential to eliminate tumors, but works best for select patients. Engineering T cells to bypass cancer’s defenses could help expand treatment eligibility to more patients.

How cancer cells can become immortal – new research finds a mutated gene that helps melanoma defeat the normal limits on repeated replication

One enzyme plays a key role in how tumor cells replicate and divide indefinitely. Identifying the genes that give these cells their immortality could provide new drug targets to treat cancer.

How gene-edited white blood cells are helping fight cancer

In a new study, a team of US scientists have used gene editing to change the genetic code of white blood cells and transform them into more efficient tumor fighting cells. How did they do it?

Discovery of how cells sense oxygen levels earns Nobel Prize

Oxygen is vital for life, so much so that cells can sense when there isn’t enough and adapt almost instantly. So how do they do it? The winners of the 2019 Nobel Prize for Physiology figured it out.

Potential treatment for eye cancer using tumor-killing virus

When you think of viruses, you might think of the horrible illnesses they cause, like flu or Ebola. But now researchers are learning how to use the unique traits of viruses to treat disease.

Glioblastoma, a formidable foe, faces a ‘reservoir of resilience’ in McCain

A diagnosis of glioblastoma did not keep John McCain from the Capitol to cast a crucial vote that could end Obamacare. His actions are a reminder that stats are one thing but human beings, another.
