Certain types of biochemical processes can impair the immune system’s ability to recognize and kill cancer cells. Purdue University’s W. Andy Tao and his associates have developed a new way to study these processes. They demonstrated the validity of their method in experiments involving leukemia and rare liver cancer cell lines.
Tao and 10 co-authors published the details of their new method Aug. 1 in the Journal of the American Chemical Society. Their work provides a system for tracking and identifying the various types of proteins and an unheralded but widely secreted class of bioparticles called extracellular vesicles (EVs) that can compromise immunotherapy.
Researchers from the University of Maryland School of Medicine (UMSOM), Brigham and Women’s Hospital in Boston, and other North American institutions, have provided the first technical description for using focused ultrasound to reliably open the blood-brain barrier. The findings, recently published in Device, pave the way for expanding the use of this experimental device to open the blood-brain barrier to improve treatments and diagnostics for patients with brain tumors and other neurological disorders.
A research team at Kyoto University has discovered STAG3-cohesin, a new mitotic cohesin complex that helps establish the unique DNA architecture of spermaotogonial stem cells (SSCs), the stem cells that give rise to sperm. This "DNA organizer" is crucial for sperm production in mice: without STAG3, SSCs cannot differentiate properly, leading to a fertility problem. In humans, the researchers found that STAG3 is highly expressed in immune B cells and in B-cell lymphomas (a type of blood cancer), and blocking it slowed the growth of these cells. This discovery might open the door to new strategies for treating infertility and certain cancers.
