The compound thymoquinone (TQ) selectively kills prostate cancer cells at advanced stages, according to a new study published in Oncogene. Led by researchers at Kanazawa University, the study reports that prostate cancer cells with a deletion of the SUCLA2 gene can be therapeutically targeted. SUCLA2-deficient prostate cancers represent a significant fraction of those resistant to hormone therapy or metastatic, and a new therapeutic option for this disease would have immense benefits for patients.
Hormone therapy is often chosen for the treatment of metastatic prostate cancer but nearly half of patients develop resistance to the treatment in as little as 2 years. A mutation in RB1, a tumor suppressor gene that keeps cell growth under control, has been pegged as a particularly strong driver of treatment resistance and predicts poor outcome in patients.
“Mutations in tumor suppressor genes are enough to induce initiation and malignant progression of prostate cancer, but
The death of neurons, whether in the brain or the eye, can result in a number of human neurodegenerative disorders, from blindness to Parkinson’s disease. Current treatments for these disorders can only slow the progression of the illness, because once a neuron dies, it cannot be replaced.
Now, a team of researchers from the University of Notre Dame, Johns Hopkins University, Ohio State University and the University of Florida has identified networks of genes that regulate the process responsible for determining whether neurons will regenerate in certain animals, such as zebrafish.
“This study is proof of principle, showing that it is possible to regenerate retinal neurons. We now believe the process for regenerating neurons in the brain will be similar,” said David Hyde, professor in the Department of Biological Sciences at Notre Dame and co-author on the study.
For the study, published in Science, the researchers mapped the genes
Stanford University scientists have identified a new class of solid materials that could replace flammable liquid electrolytes in lithium-ion batteries.
The low-cost materials — made of lithium, boron and sulfur — could improve the safety and performance of electric cars, laptops and other battery-powered devices, according to the scientists. Their findings are published in a study in the journal ACS Applied Materials & Interfaces.
“A typical lithium-ion battery has two solid electrodes with a highly flammable liquid electrolyte in between,” said study lead author Austin Sendek, a visiting scholar in Stanford’s Department of Materials Science & Engineering. “Our goal is to design stable, low-cost solid electrolytes that also increase the power and energy output of the battery.”
Battery electrolytes shuttle lithium ions between the positive and negative electrode during charging and discharging. Most lithium-ion batteries use a liquid electrolyte that can combust if the battery is punctured
Meteorologists track hurricanes over the oceans, forecasting where and when landfall might occur so residents can prepare for disaster before it strikes. What if they could do the same thing for droughts?
Stanford scientists have now shown that may be possible in some instances — the researchers have identified a new kind of “landfalling drought” that can potentially be predicted before it impacts people and ecosystems on land. They found that these droughts, which form over the ocean and then migrate landward, can cause larger and drier conditions than droughts that occur solely over the land. Of all the droughts affecting land areas worldwide from 1981 to 2018, roughly one in six were landfalling droughts, according to the study published Sept. 21 in Water Resources Research.
“We normally don’t think about droughts over the ocean — it may even sound counterintuitive. But just as over land, there can be times
