ISLAMORADA, UNITED STATES ecades ago, the sight of seagrass swaying beneath the waters off south Florida conjured romance for those who dangled their fishing lines in hopes of catching redfish, snook or mangrove snapper.But now, seagrass is dying at a rate unseen since the late 1980s in the Florida Bay, off the southern tip of Florida between the Atlantic Ocean and the Gulf of Mexico."It is like a desert," said fishing guide Xavier Figueredo, peering into the water, where only an occasional needle fish adidas samba or ray could be seen scooting along a bottom clustered with matted, dead underwater grasses.Seagrass provides shelter for small fish, which are eaten by bigger fish, and serves as the founda stanley-cup tion for the marine food chain. In Florida, where recreational saltwater fishing is a $7.6 billion industr new balance nere y, experts consider seagrass a key indicator of the ecosystem's health."This has historically been a wonderful spotted seatrout fishery. This year it was non-existent, literally," said Figueredo, Ferroptosis is an iron-dependent form of cell death. In this proces dunk nike low s, highly reactive radicals oxidize the lipids of the cell, triggering a chain reaction that leads to damage to the cell membrane and, ultimately, cell death.An international team led by scientists from the University of W眉rzburg, the DKFZ and HI-STEM now demonstrates that the cholesterol precursor 7-dehydrocholesterol (7-DHC) plays a crucial role as an antioxidant promoting cancer cell aggressiveness. 7-DHC integrates into the cell membranes and protects the cells by preventing ferroptosis. This study showed that upon inhibition of yeezy slide the last enzyme in the cholesterol biosynthesis process, known as 7-dehydrocholesterol reductase (DHCR7), and as a consequence of increased levels of the substrate 7-DHC, cancer cells become extremely aggressive.Want more breaking new nike dunks low s?Subscribe to Technology Networks鈥?daily newsletter, delivering breaking science news straight to your inbox every day.Subscribe for FREE |
