Title	Novel Venetin-1 nanoparticle from earthworm coelomic fluid as a promising agent for the treatment of non-small cell lung cancer
Description	The present research shows the antitumor activity of a protein-polysaccharide complex Venetin-1 obtained from the fluid of Dendrobaena veneta earthworms against A549 cancer cells. The investigations are a continuation of experiments on the antitumor activity of the coelomic fluid from this species. The Venetin-1 nanoparticle was obtained after thermal treatment of the coelomic fluid, separation from coelomocytes, filtration, and lyophilization. The preparation showed a selective effect on cancer cells while sparing normal cells. Venetin-1 was effective against the lung cancer cells at doses of 31.3 and 62.5 µg/ml, which was imaged using light microscopy and scanning electron microscopy (SEM). The cells died mainly via the apoptosis pathway. Necrotic cells appeared sporadically in the microscopic view. SEM imaging revealed complete destruction of the A549 cells after the incubation with Venetin-1. The atomic force microscopy (AFM) analyses showed changes in the topography, peak force error images, and Young’s modulus (elasticity) of the A549 cells after the incubation with Venetin-1. The transmission electron cryomicroscopy (Cryo-TEM) microscopic analysis indicated a polymeric nature of the analyzed preparation. The samples of Venetin-1 showed a very homogeneous size profile with the microparticle size determined to be around 58.23 nm. A significant decrease in Venetin-1 binding to sphingomyelin was observed. Venetin-1 lost its pore-forming activity or deactivation of the pore-forming activity occurred. This confirms the lack of hemolytic capacity of Venetin-1 towards red blood cells.
