Prostate cancer regulator plays role in COVID-19, providing a promising treatment lead
By taking a lesson from prostate cancer, researchers now have a promising lead on a treatment for COVID-19. They found that, just like in prostate cancer, TMPRSS2 is regulated by the androgen receptor in the lungs. And notably, blocking the androgen receptor led to lower expression of TMPRSS2, which led to decreased coronavirus infection in mice and cellular models.

In order to improve their understanding of how CTCL develops in hopes of developing new therapies, a team of Moffitt immunologists and hematologists conducted a series of studies. In an article published in The Journal of Clinical Investigation, they demonstrate that decreased expression of the protein SATB1 contributes to CTCL development and that drugs that cause SATB1 to become re-expressed may be potential treatment options for this disease.
Discovery: How Colorado Potato Beetles Beat Pesticides
New research shows that pesticide alter how Colorado potato beetles manage their DNA. These changes were passed down two generations suggesting that rapid resistance to pesticides may not require beetles to evolve their genetic code. Instead they may simply use existing genes to tolerate toxins already found in potatoes. The scientists were surprised that these epigenetic changes, triggered by a single tiny dose of pesticide, were maintained through multiple rounds of sexual reproduction.

Scientists from the MIPT Research Center for Molecular Mechanisms of Aging and Age-Related Diseases have joined forces with their colleagues from Jülich Research Center, Germany, and uncovered how sodium ions drive glutamate transport in the central nervous system. Glutamate is the most important excitatory neurotransmitter and is actively removed from the synaptic cleft between neurons by specialized transport proteins called excitatory amino acid transporters (EAATs)
Big step with small whirls
Skyrmions are small magnetic objects that could revolutionize the data storage industry and also enable new computer architectures. However, before they can be utilized in such applications, there are still a number of challenges that need to be overcome. A team of Empa researchers has now succeeded for the first time in producing a tunable multilayer system in which two different types of skyrmions – the future bits for “0” and “1” – can exist at room temperature, as they recently reported in the renowned journal Nature Communications.

Statewide Retail Alcohol Compliance Checks Cut Drink-Driving Crashes Among Drivers Under-21 Years Old
Regular statewide retail checks for compliance with the legal drinking age are associated with a sustained reduction in alcohol-related crashes for drivers aged under 21, according to an analysis of 11 years’ data from South Carolina. Previous research has shown that reductions in underage drinking lead to a decrease in drink-driving and alcohol-related crashes. However, few studies have assessed the impact of purposeful alcohol compliance checks – in which authorities use an underage informant to attempt to buy alcohol – on drink-related road accidents. The new study, reported in Alcoholism: Clinical and Experimental Research, evaluated the impact of the South Carolina Alcohol Enforcement Team (AET) program for reducing retail alcohol access to underage youth on drinking and driving crashes among drivers under 21 years old.
