Nature ion channels play significant role in the living organisms, which can translocate physiological relevant ions across the cell membranes as demand. To simulate and replace the function of nature channels, researchers are encouraged to develop artificial channels using simple and smart supramolecular structures. Inspired by the complementary hydrogen bonding interactions of DNA/RNA, a team of researchers from East China University of Science and Technology reported a simple synthetic supermolecule system to form stable ion channels in the lipid membranes, and the efficient transport of K+ triggers apoptosis of cancer cells. It represents one of the few examples of using complementary hydrogen bonding interactions to construct effective ion channels and offers new perspectives in the developments of anticancer drugs.
Alcoholic and non-alcoholic fatty liver disease (NAFLD) are well-known risk factors for colorectal cancer (CRC). NAFLD has emerged as a heterogenous disease tightly linked to metabolic dysfunction and has been redefined under the umbrella term ‘steatotic liver disease’ (SLD). However, CRC risk variations across different SLD subgroups remain unknown. Now, researchers from Japan have discovered that the risk of CRC varies significantly among SLD subgroups, with patients with alcoholic liver disease being at higher risk.
New findings from researchers at the Broad Institute of MIT and Harvard and the Dana-Farber Cancer Institute could help make immunotherapies for brain cancer more effective. The team analyzed almost 200,000 individual immune cells in tumor samples taken from patients with glioma, the most common and aggressive type of primary brain cancer. In Nature, the researchers describe four gene expression “programs” — sets of genes with coordinated activity — that either suppress the immune system or make it more active. Defining and understanding what drives these programs could one day help researchers target them with new drugs to dial up or down specific parts of the immune system to improve patient response to immunotherapy.
A study led by the Joe C. Wen School of Population & Public Health at the University of California, Irvine has revealed possible links between exposure to per- and polyfluoroalkyl substances in drinking water and an increased risk of certain childhood cancers.
