Cancer metastasis is a major cause of cancer-related mortality. Strategies to reduce metastases are needed especially in lung cancer, the most common cause of cancer mortality. We previously reported increased ubiquitin-specific peptidase 18 (USP18) expression in lung and other cancers. Engineered reduction of USP18 expression repressed lung cancer growth and promoted apoptosis. This deubiquitinase (DUB) stabilized targeted proteins by removing the complex interferon-stimulated gene 15 (ISG15). This study explores if the loss of USP18 reduced lung cancer metastasis. USP18 knock-down in lung cancer cells was independently achieved using small hairpin RNAs (shRNAs) and small interfering RNAs (siRNAs). USP18 knock-down reduced …

Effects Of Beaver Dams On Stream And Riparian Conditions On Public Lands In The United States’ Inland Northwest, Brett B. Roper

Western North American Naturalist

A before-after control-impact (BACI) design was used to simultaneously evaluate how stream habitat, macroinvertebrate communities, stream temperatures, and riparian conditions responded to beavers building dams within a stream reach. Summarized conditions describing beaver-dammed and undammed stream reaches suggested that 13 of the 18 evaluated metrics differed. After accounting for beavers’ selection of lower-gradient stream reaches with less forested cover, the number of stream and riparian metrics that differed significantly dropped to 5. Beaver dams increased pool area and depth, despite failing to increase the frequency of wood >10 cm in diameter. This suggests that beavers build dams utilizing pieces of …
