Scientists uncover a new approach for treating aggressive cancer

Researchers have uncovered a new role of a chromatin-modulatory enzyme, termed EZH2, during cancer development. They then designed a new small-molecule, MS177, based on the proteolysis-targeting chimera (PROTAC) technology, that targets both EZH2 and cMyc and thus inhibits cancer growth.

MRI may lower breast cancer deaths from variants in 3 genes

Annual MRI screenings starting at ages 30 to 35 may reduce breast-cancer mortality by more than 50% among women who carry certain genetic changes in three genes, according to a comparative modeling analysis. The predictions involve pathogenic variants in ATM, CHEK2 and PALB2 genes — which collectively are as prevalent as the much-reported BRCA1/2 gene mutations.

Pushing past pancreatic tumors’ defenses

Researchers found that some cancer cells weave a deactivating signal into a protective coat of armor, immobilizing and excluding T cells that would otherwise kill them. This immune deactivation pathway offers a promising new therapeutic approach for pancreatic, breast, and colorectal cancers.

Pandemic upends breast cancer diagnoses

Researchers surveyed and compared early- and late-stage breast and colorectal cancer diagnoses in patients in pre-pandemic 2019 and in 2020, the first full year of the COVID-19 pandemic, discovering fewer of the former and more of the latter as patients delayed care.

New drug combination effective for patients with advanced ovarian cancer

A new study shows ixabepilone plus bevacizumab (IXA+BEV) is a well-tolerated, effective combination for treatment of platinum/taxane-resistant ovarian cancer compared to ixabepilone (IXA) alone.

‚Amazing‘ nanoparticles from maize: A potent and economical anti-cancer therapeutic

Nanomaterials have revolutionized the world of cancer therapy, and plant-derived nanoparticles have the added advantage of being cost-effective and easy to mass produce. Researchers have recently developed novel corn-derived bionanoparticles for targeting cancer cells directly, via an immune mechanism. The results are encouraging, and the technique has demonstrated efficacy in treating tumor-bearing laboratory mice. Moreover, no serious adverse effects have been reported in mice so far.

Initiative to map the cholangiocarcinoma (CCA) landscape in Europe will help improve patient outcomes

Bile duct cancer, also known as cholangiocarcinoma (CCA), is a rare cancer often diagnosed only at an advanced stage. A comprehensive analysis of diagnostic, prognostic, and therapeutic aspects of over 2,200 patients in Europe now provides a valuable knowledge base for raising awareness and managing CCA to improve outcomes.

Mapping mutation ‘hotspots’ in cancer reveals new drivers and biomarkers

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.

Suppressing the spread of tumors

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

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

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

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.
