A study in mice demonstrates that exposure to contaminating mixtures of metals and drug residue increases damage to health, and evaluates the positive effects of a diet enriched in selenium to reduce this harm. A study in mice conducted by the University of Cordoba proves that exposure to contaminating mixtures of metals and drug residue increases damage to health, and evaluates the positive effects of a diet enriched in selenium to reduce this harm People are exposed daily, through the environment and their diets, to external substances that can be harmful to their health. Metals and the residue of pharmaceuticals, for example, in high doses, contaminate water and food, creating mixtures where they can interact, with this increasing their individual toxicity. Analyzing the effects of environmental pollution on organisms is essential to develop regulations establishing maximum doses of these pollutants for people. But, what about mixtures of pollutants? What happens when, even when faced with accepted doses, the different compounds interact with each other? To understand the health effects of exposure to these "cocktails of contaminants," a team from the Biochemistry and Molecular Biology Department at the University of Cordoba, comprised of Nieves Abril, Paula Huertas, María José Prieto and Juan Jurado, evaluated, in mice, the toxicity of a mixture of contaminants that is very common in the environment and that accumulates along the food chain: a combination of metals (arsenic, cadmium, mercury) and drugs (diclofenac, flumequine). In order to determine how these compounds interacted with each other, "we studied the controlled exposure of mice to this mixture and analyzed how it affects the proteins in the liver; that is, how their liver proteostasis changes when ingesting these mixtures of contaminants for two weeks," explained Professor Nieves Abril. Their conclusion is negative: the cocktail effect creates synergy between these compounds, doing increased damage to health increase when the compounds act together. "We used a massive protein detection technique (shotgun proteomic), which allowed us to compare how the proteins of the group exposed to the mixture of contaminants were altered compared to the control group," April explained. Of the proteins affected, they selected 275 as sentinels to verify what was changing and, after computer analysis, they were able to determine the metabolic pathways that were altered and their consequences for health. These analyses revealed a disproportionate defense response having a contrary and harmful effect on the system. The researcher stressed that "although these pollutants generated oxidation in the cells separately too, when they acted together we found that the oxidation was so intense that all the antioxidant defense responses were activated continuously, without deactivating them, which ends up doing damage and causing many proteins to stop working." The analyses showed a sustained expression of the response mediated by NRF2, which is the regulator that sets in motion a good part of the antioxidant defenses, which caused a reducing stress. Selenium as hope The study also provides hope, as selenium could be a way to reduce the damage caused by exposure to these pollutants. A third group of mice were given doses of selenium, a mineral often found in vitamin supplements found in pharmacies, and proteomic analyses showed relief from the molecular damage done by the pollutants. Selenium itself is an oxidant, but in low doses it activates responses in a controlled manner, predisposing the body to better defense. With the results of this experiment, which was made possible thanks to Research Support (SCAI) and Experimental Animals (SAEX) services, knowledge of the effects of the pollutants to which society is exposed on a daily basis has been expanded, and a way has been glimpsed to reduce the damage they producethrough the use of selenium.

Company looks forward to anticipated 2023 milestones, including first commercial sale of XACIATO™, enrollment in Ovaprene® pivotal Phase 3 study, and topline data from DARE-PDM1 Phase 1 studySAN DIEGO, Sept. 05, 2023 (GLOBE NEWSWIRE) -- Daré Bioscience, Inc. (NASDAQ: DARE), a leader in women’s health innovation, today announced the completion of its registered direct offering of common stock and warrants to purchase common stock priced at-the-market under Nasdaq rules with an institutional investor and an investor affiliated with the licensor of one of the company’s early stage product candidates. The aggregate gross proceeds to Daré, before deducting offering expenses payable by Daré, were $7.0 million. The closing occurred on September 1, 2023. “This financing strengthened our balance sheet, providing cash to help us deliver on important portfolio milestones this year,” said Sabrina Martucci Johnson, President and CEO of Daré Bioscience. “In addition to the commercial launch of XACIATO in the U.S. by Organon, we are looking forward to the commencement of patient enrollment in our pivotal Phase 3 clinical study of Ovaprene, our investigational, hormone-free, monthly intravaginal contraceptive, and topline data from our Phase 1 clinical study of DARE-PDM1, an investigational proprietary hydrogel formulation of diclofenac we are developing as a vaginally administered treatment for primary dysmenorrhea, more commonly referred to as menstrual cramps and pain,” continued Ms. Johnson. “We also look forward to an end-of-Phase-2 meeting, targeted for 2023, with the FDA for our Sildenafil Cream, 3.6% program, to support Phase 3 commencement in early 2024; our investigational formulation of sildenafil is designed to treat female sexual arousal disorder and/or female sexual interest/arousal disorder utilizing the active ingredient in Viagra®. In addition, we are pleased to announce that we previously entered into a license agreement with Douglas Pharmaceuticals, a New Zealand based pharmaceutical company, under which we acquired exclusive rights to develop and commercialize in the United States an investigational, novel proprietary lopinavir and ritonavir combination soft gel vaginal insert for the treatment of cervical intraepithelial neoplasia, also known as cervical dysplasia. There is no FDA-approved pharmaceutical treatment for cervical dysplasia, a precancerous condition in women strongly linked to HPV infection, the most common sexually transmitted infection in the U.S. Current surgical procedures to treat cervical dysplasia are invasive and can adversely impact future pregnancies. A pharmaceutical approach could provide women with an important alternative to surgery to treat this condition.” Daré’s completed equity financing included minority participation by an investor affiliated with Douglas.
