Mapping mutation ‘hotspots’ in cancer reveals new drivers and biomarkers
10. Februar 2022
Researchers have identified a previously unrecognized key player in cancer evolution: clusters of mutations occurring at certain regions of the genome. These mutation clusters contribute to the progression of about 10% of human cancers and can be used to predict patient survival.
Gut bacteria linked to immune suppression in pancreatic cancer
9. Februar 2022
Researchers have shown how probiotic bacteria in the gut could undermine immunity in pancreatic cancer, pointing toward more personalized cancer treatments.
Suppressing the spread of tumors
9. Februar 2022
When tumors spread, cancer cells migrate to other parts of the body through the blood or lymphatic vessels. Scientists have now found a new protein that prevents cancer cells from doing so by making them stick more tightly to their surroundings. Their findings could in the future help doctors determine the aggressiveness of a tumor and fine-tune the therapy.
Gene regulation in mammals offers clues connecting pregnancy and cancer metastasis
8. Februar 2022
In many mammals including humans, the placenta invades the wall of the uterus during pregnancy in the same way that cancer cells invade surrounding tissues. Using genomic sequences and gene expression information, researchers were able to predict specific signaling proteins that drive the expression of genes that decrease the susceptibility of invasion in human cells. Using a custom fabricated bio chip, the researchers confirmed that these predicted proteins did in fact decrease the invasion of both cancer and placental cells.
New personalized test for an earlier and more accurate prediction of cancer relapse
8. Februar 2022
Researchers have developed a new protocol for monitoring acute lymphoblastic leukemia (ALL), the most common cancer in children, to inform more effective treatment strategies and detect disease recurrence. The personalized mediator probe PCR (MP PCR) uses multiple genomic cancer cell markers in a single assay and is simpler than current techniques. It improves monitoring clonal tumor evolution to detect a relapse sooner and avoid false negative results.
Advanced prostate cancer antibody drug shows success in pet dogs
8. Februar 2022
Mice are typically used as models in advanced prostate cancer research, but the profound differences between them and humans has long bedeviled the translation of findings from the animal to success in people. Dogs however are the only other animal that suffers from a significant incidence of prostate cancer, and researchers are finding them much more enlightening subjects in identification of drugs that show promise for human patients.
New path to treat advanced triple-negative breast cancer
3. Februar 2022
A new study shows inhibition of the CECR2 gene prevents triple-negative breast cancer from advancing or metastasizing.
Magnetic seeds used to heat and kill cancer
3. Februar 2022
Scientists have developed a novel cancer therapy that uses an MRI scanner to guide a magnetic seed through the brain to heat and destroy tumors.
Simplified antibiotic may set the stage for antitumor treatments
1. Februar 2022
Garden soil houses a variety of bacteria and their natural byproducts — including one that may help halt tumor growth. Lankacidins are molecules that can be isolated from Strepomyces rochei, a common bacterium in soil. In addition to antimicrobial properties, a type of lankacidins, called lankacidin C, can inhibit tumor activity in various cancer cell lines, including leukemia, melanoma, ovarian and breast cancers. Lankacidin C offers a potential foundation on which to design anticancer drugs, but its structure is complicated and difficult to manipulate, according to an international research group. The same group recently identified where antitumor activity is housed on the molecule and has now used that information to simplify lankacidin as a potential starting point to engineer treatments.
New blood test combined with image-based prostate cancer screening reduces harms and costs
29. Januar 2022
The combination of a novel blood test and magnetic resonance imaging (MRI) can reduce overdiagnosis of low-risk cancers as well as societal costs in prostate cancer screening, according to a cost-effectiveness study.

29. Januar 2022
A study has revealed a potential new way to treat secondary breast cancer that has spread to the brain, using existing drugs.
Live cells discovered in human breast milk could aid breast cancer research
29. Januar 2022

Players needed to solve puzzles and help advance cancer research
28. Januar 2022
Scientists have just launched GENIGMA, a videogame that enlists players to solve puzzles while generating real-world scientific data that can detect alterations in genomic sequences and ultimately advance breast cancer research. The game was created to boost worldwide research efforts that depend on cancer cell lines, a critical resource used by scientists to study cancer and test new drugs to treat the disease. One of the limitations of cancer cell lines are a lack of high-resolution genome reference maps, which are necessary to help researchers interpret their scientific results.
