The neonicotinoid imidacloprid impairs the predatory performance and functional response of the jumping spider Helpis minitabunda (Araneae, Salticidae)

  The neonicotinoid imidacloprid impairs the predatory performance and functional response of the jumping spider Helpis minitabunda (Araneae, Salticidae) Abstract The neonicotinoid imidacloprid can cause lethal and sublethal effects in non-target organisms, including impaired behavior, reduced fertility, disrupted locomotion, and reduced predatory performance in arthropods. Spiders are among the most abundant arthropod predators in terrestrial ecosystems, including agricultural ecosystems, yet the effects of neonicotinoids on the predatory function of jumping spiders remain poorly understood. The functional response of a predator describes how predation rates change with prey density and is key to understanding predator–prey dynamics. We tested whether acute exposure to a commercial formulation of imidacloprid at field-recommended concentrations alters the functional response of the Aussie bronze jumping spider, Helpis minitabunda (L. Koch, 1880). We compared the predation of treat...

Could venom-derived therapeutics resolve treatment resistance in refractory EAC?

Abstract

The incidence of esophageal adenocarcinoma is rising in Western countries. Despite advances in chemotherapy and immunotherapy, the prognosis remains poor, with an overall 5-year survival rate below 15%. A major challenge is the cancer’s poor and often unpredictable response to current treatments. Animal venoms represent a promising yet underexplored source of therapeutic agents, offering millions of structurally diverse and highly potent bioactive peptides that can modulate a wide array of molecular targets. However, only a small fraction of these peptides has been pharmacologically characterized. This review presents the therapeutic potential of venom-derived peptides in cancer treatment, summarizes the role of ion channels in esophageal adenocarcinoma (EAC), and discusses peptides targeting ion channels that may offer new opportunities for future EAC treatment.
