Research pinpoints new therapeutic opportunity for ovarian clear cell carcinomas

Mutations in the ARID1A gene are present in more than 50% of ovarian clear cell carcinomas (OCCC), for which effective treatments are lacking. Scientists at The Wistar Institute discovered that loss of ARID1A function enhances a cellular stress response pathway that promotes survival of cancer cells, which become sensitive to pharmacological inhibition of this pathway. These findings were published online in Cancer Research, a journal of the American Association for Cancer Research, and point to a new therapeutic opportunity for this type of ovarian cancer for which new solutions are urgently needed.

Thiol-based mucolytics show potent allosteric inhibition of SARS-CoV-2-ACE2 binding via disulfide reduction

A compelling report, recently released on the bioRxiv* preprint server, describes unexpectedly powerful inhibition of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) by thiol-based mucolytic compounds P2119 and P2165, by preventing the virus spike from binding to its host cell receptor, the angiotensin-converting enzyme 2 (ACE2).

SARS-CoV-2 causes ER-stress-activated unfolded protein response leading to cell death

A new study describes the varying ways in which the virus co-opts the machinery of the host cell following infection to evade or modulate the host immune response, alter the pattern of translation of viral proteins, and the release of new viral particles.

Study examines SARS-CoV-2 replication in cells using super-resolution microscopy

Despite tremendous efforts by the global scientific community to curb the spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), by developing more efficient testing protocols, therapies, and vaccines at a rapid pace, relatively little is known about the dynamics of SARS-CoV-2 replication within cells.

Researchers develop new imaging technique for studying nanoscale coronavirus-host interactions

Lei S. Qi of Stanford University, California, and colleagues published research showing a potential framework to better characterize coronaviruses' biology. While most high-resolution imaging techniques show the life cycle of coronaviruses, identifying viral or host proteins and genomes remains poorly understood. Their results use multi-color super-resolution imaging allows them to study nanoscopic parts of the coronavirus, including RNA.
