Team identifies a nutrient that cancer cells crave
by Rockefeller University Arginine codons and residues are frequently lost and are associated with an increase in ASS1 expression. (A) Heatmap depicting codons gained (red) and lost (blue) across the TCGA. Gains and losses are normalized to the total number of missense and silent mutation events per sample for each cancer type. (B) Qualitative chord diagram...
How cancer cells die: Scientists explore new pathways of pyroptosis, killer kin of apoptosis
by Delthia Ricks, Medical Xpress Lymphoid BLaER1 cells undergo PANX1-dominant lysis. (A to C) BLaER1 cells were treated with topoisomerase poisons doxorubicin (2 μM) or etoposide (50 μM) for 24 hours. Concurrent treatment with PANX1 inhibitor trovafloxacin (20 μM) or NLRP3 inflammasome inhibitor MCC950 (10 μM) were as indicated. In (A and C), quantification of...
Researchers design ‘prodrug’ that targets cancer cells’ big appetite for glutamine, leaving healthy cells unharmed

Fairman, CMI, FAMI, Department of Art as Applied to Medicine Johns Hopkins Medicine researchers have revamped an anti-cancer drug to better target cancer cells and leave healthy tissues...
“Electrical language” of cancer cells may spill secrets of tumor growth
By Nick Lavars November 14, 2022 Scientists have discovered a new type of electrical activity in cancer cells Depositphotos By using machine learning and cutting-edge microscopes, scientists have uncovered what they believe to be a new form of communication between cancer cells. Described as a “type of electrical language,” the discovery may be key to...
Cancer cells adopt hitherto unknown state to facilitate metastasis
by Susann Huster, Leipzig University Credit: Pixabay/CC0 Public Domain The ancient Egyptians, as described in the Ebers Papyrus, already knew that palpation—feeling for hardened lumps—can help diagnose breast cancer. Palpation is still an important element in early screening for breast cancer. On the other hand, measurements on individual cancer cells show that they are softer...
New genetically engineered herpes virus kills cancer cells
A genetically modified version of the herpes virus has shown great potential in treating advanced cancers, according to a report by the Institute of Cancer Research in London published on Thursday. A promising therapy Although the treatment is still in early trials, researchers have found that RP2, a modified version of the herpes simplex virus,...
Keeping aggressive cancer cells in check by blocking a protein responsible for repairs
by Catarina Pietschmann, Max Delbrück Center for Molecular Medicine Three-dimensional culture of human breast cancer cells, with DNA stained blue and a protein in the cell surface membrane stained green.

Researchers turn cancer cells into less harmful cell types
by University of Basel High-throughput drug screen reveals estrogen receptor α (ERα) induction in triple-negative breast cancer (TNBC) upon polo-like kinase 1 (PLK1) inhibition. A Schematic of the high-throughput drug screen to identify inhibitors that induce ERα signaling in TNBC. Cells without active ERα signaling do not express GFP, whereas cells with active ERα signaling...
Breaking down proteins: How starving cancer cells switch food sources
by German Cancer Research Center Human cancer cells (cell nucleus in blue) feeding on protein (Albumin, labeled in green). The proteins are digested and broken down into amino acids in the lysosomes (magenta). Credit: W. Palm / DKFZ Cancer cells often grow in environments that are low in nutrients, and they cope with this challenge...
