Preliminary proteomic analysis of mouse lung tissue treated with cyclophosphamide and Venetin-1.

Cyclophosphamide (CPAm) is a widely used chemotherapeutic agent that exhibits potent anti-cancer properties but is often associated with debilitating side effects. Despite its efficacy, the management of CPAm-induced toxicities remains a significant clinical challenge. There has been growing interest in exploring complementary and alternative therapies to mitigate these adverse effects in recent years, and this may be a chance for the earthworm-derived preparation, Venetin-1.

Prospects of earthworm coelomic fluid as a potential therapeutic agent to treat cancer.

Cancer is a major public health concern because it is one of the main causes of morbidity and mortality worldwide. As a result, numerous studies have reported the development of new therapeutic compounds with the aim of selectively treating cancer while having little negative influence on healthy cells. In this context, earthworm coelomic fluid has been acknowledged as a rich source of several bioactive substances that may exhibit promising anticancer activity.

Resistance of Dickeya solani strain IPO 2222 to lytic bacteriophage ΦD5 results in fitness tradeoffs for the bacterium during infection.

Resistance to bacteriophage infections protects bacteria in phage-replete environments, enabling them to survive and multiply in the presence of their viral predators. However, such resistance may confer costs for strains, reducing their ecological fitness as expressed as competitiveness for resources or virulence or both. There is limited knowledge about such costs paid by phage-resistant plant pathogenic bacteria in their natural habitats.

Polysaccharide-protein complex from coelomic fluid of Dendrobaena veneta earthworm exerts a multi-pathway antiplatelet effect without coagulopathy and cytotoxicity.

There is a pressing need to identify novel antiplatelet agents, an alternative to acetylsalicylic acid and thienopyridines, to broaden the prevention of cardiovascular events, the leading cause of global morbidity and mortality. Invertebrate coelomocytes structurally and functionally resemble the thrombocyte-like cells of vertebrates; therefore, the coelomic fluid in which they are suspended may contain agents controlling their clumping abilities. However, whether coelomocytes-free coelomic fluid may also affect human platelet activities was not a subject of any study.
