Cancer Cells’ DNA Repair Disrupted to Increase Radiation Sensitivity
Shortening end caps on chromosomes in human cervical cancer cells disrupts DNA repair signaling, increases the cells’ sensitivity to radiation treatment, and destroys them more rapidly, according to new findings. More..
Tumor Suppressor Gene Blocks Formation of Diffuse Large B-Cell Lymphomas
A molecular pathway helps to explain how the oncogene BCL6 acts to generate diffuse large B-cell lymphoma, which may present opportunities for the development of specific chemotherapeutic agents. More..
Lichen-Derived Dye May Prevent Alzheimer’s by Neutralizing Toxic Peptides
A dye derived from lichens is among the candidate compounds being tested for their ability to convert toxic prefibrillar assemblies of amyloid-beta polypeptides into mature, end-stage amyloid fibrils that are thought to be largely nontoxic. More..
New Incubators Incorporate Hydrogen Peroxide Vapor Decontamination Package
A novel decontamination system for CO2 incubators prevents growth of microorganisms and safeguards precious cell cultures. More..
Newly Characterized Toxin-Antitoxin Module May Lead to Improved Antibiotics
An international team of molecular microbiologists has detailed the molecular pathway responsible for a toxin-antitoxin system in Escherichia coli that becomes activated when the bacteria are put under stress. More..
Adult Stem Cells Use Specific Pathways to Repair Damaged Muscle
When a muscle is injured, dormant adult stem cells called satellite cells are signaled to activate and help in repairing the muscle. More..
