Nuclear DNA gets cut and activates immune system to attack cancer cells
The enzyme MUS81 cuts DNA in the nucleus of cancer cells, causing the cut DNA to move to the cytoplasm instead of becoming degraded. The out-of-place DNA triggers an immune response against cancer cells. Discovering this new means of enhancing anti-cancer immune responses could lead to more effective cancer therapies using a combination of a MUS81-stimulating drug and an immunotherapy. (2016-05-10)

Starving pancreatic cancer cells: Scientists identify potential pancreatic cancer target
Researchers have found that a protein called SLC6A14 is overexpressed by several fold in pancreatic tumors taken from patients and in cancerous pancreatic cells lines compared with normal pancreatic tissue or normal pancreatic cells. SLC6A14 transports amino acids into cells to help with cellular metabolism. (2016-10-17)

Researchers try to determine why cancer cells don't commit suicide
Researchers at Wake Forest University Baptist Medical Center are using an innovative approach to study one of the fundamental aspects of how cancer develops. Normal cells are pre-programmed to kill themselves by a process called apoptosis if they grow too fast or at the wrong time or place -- cancer cells do not exhibit this same cell suicide response. (2003-09-02)

Blood test provides clues to bladder cancer patients' prognoses
New research indicates that about one-quarter of patients with bladder cancer treated with radical surgery on curative intent have detectable levels of tumour cells circulating in their blood. The presence of circulating tumour cells was also a predictor of cancer recurrence and death. (2017-02-13)

Cancer protein chops cell anchors
Matrix metalloproteinases (MMPs) act like machetes in a forest: they clear a path to allow cell movement. Now researchers have found that they also chop up the proteins that keep cells anchored in place, thus dislodging cancer cells and allowing them to move around the body. (2001-05-27)

New study shows promise for preventing therapy resistance in tumor cells
A new study led by University of Kentucky researchers suggests that activating the tumor suppressor p53 in normal cells causes them to secrete Par-4, another potent tumor suppressor protein that induces cell death in cancer cells. This finding may help researchers decipher how to inhibit the growth of tumors that have become resistant to other treatments. (2014-01-09)

Metabolite that promotes cancer cell transformation and colorectal cancer spread identified
Osaka University researchers revealed that the metabolite D-2-hydroxyglurate (D-2HG) promotes epithelial-mesenchymal transition of colorectal cancer cells, leading them to develop features of lower adherence to neighboring cells, increased invasiveness, and greater likelihood of metastatic spread. The finding highlights the value of targeting D-2HG to establish new therapeutic approaches against colorectal cancer. (2016-12-01)

Discovered a protein that spreads cancer
Aggressive cancer cells spread from a tumor to another part of the body through the blood vessel. To be able get in and out of the blood vessel, the cancer cell needs to penetrate tissue. Researchers from The University of Bergen have discovered a protein that the cancer cell uses like scissors to cut up tissue, so it can spread from a tumor to a new organ. (2016-04-13)

New Zealand researchers makes 'natural born killer' cell discovery
An unexpected role for a white blood cell called the Natural Killer (NK) cell -- a critical cell for ridding the body of infection and cancer, has been discovered by researchers t New Zealand's University of Otago. The NK cell is a 'vigilante' killer -- a white blood cell that destroys invaders and cancer cells through a process of 'identity card' checking. The researchers' new work shows that violent vigilante NK cells act as helper cells to start up the immune response. (2017-08-31)

Why cancer cells just won't die
When cells experience DNA damage, they'll try to repair it. But if that fails, the damaged cells are supposed to self-destruct, a process called apoptosis. A cancer researcher at Robarts Research Institute at the University of Western Ontario has identified a protein that regulates apoptosis, a new discovery which has implications for both the diagnosis and treatment of cancer. Caroline Schild-Poulter's findings are now published online in the journal Molecular Cancer Research. (2009-12-09)

How breast cancer cells sneak past local immune defenses
Breast cancer cells grow locally, then metastasize throughout the body. They succeed in establishing tumors by sabotaging local immune cells embedded in tissues, thus evading detection and destruction by the body's roving immune defenses. (2020-07-15)

Protein could offer therapeutic target for pancreatic cancer
A protein that drives growth of pancreatic cancer, and which could be a target for new treatments, has been identified by researchers at the Crick. (2019-11-12)

Fighting cancer with the help of someone else's immune cells
A new step in cancer immunotherapy: researchers from the Netherlands Cancer Institute and University of Oslo/Oslo University Hospital show that even if one's own immune cells cannot recognize and fight their tumors, someone else's immune cells might. Their proof of principle study is published in the journal Science on May 19. (2016-05-19)

Cancer patient, heal thyself
Anti-cancer immune cells are found in cancer patients, but fail to reject tumors. In the July 1 issue of the Journal of Clinical Investigation, researchers from the German Cancer Research Center, provide a method to make these cells very effective at infiltrating tumor transplants and in reducing tumor size in mice. This is a potential immunotherapy strategy for cancer treatment with appropriately reactivated anti-tumor-specific T cell subsets that already exist in patients' own body. (2004-07-01)
