At the same time, integrated processing of aquaculture by-products is an important environmental and industrial problem. Valuable biological components might be found in fish processing wastes left after manufacturing the target products (fillet, offal, etc.). In particular, antimicrobial peptides that exhibit broad-spectrum antimicrobial activity are expressed in fish. A first exploratory analysis of rainbow trout Oncorhynchus mykiss brain proteins was performed to identify the theoretical antimicrobial patterns. More than half of the identified proteins were predicted to have antimicrobial regions. The proteins included histones, vitellogenin, collagen, etc. The results may be of interest for designing drugs based on peptides active against various pathogens. The field is of importance in view of the increasing antibiotic resistance of pathogenic microorganisms.</p>","PeriodicalId":11351,"journal":{"name":"Doklady Biological Sciences","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143078919","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, the substance XMU-MP-1, an inhibitor of key MST1/2 kinases of the Hippo signaling pathway, was shown to enhance the antitumor activity of two genotoxic chemotherapeutics, etoposide and cisplatin, against Namalwa Burkitt's B-cell lymphoma cells.

The electrophysiology and mechanisms regulating the heart rhythm in Acomys are extremely poorly understood. The EEG was recorded in vivo and bioelectrical activity of the supraventricular myocardium was evaluated and mapped in spiny mice. Pacemaker-type action potentials were detected in a significant part of the right atrium, and primary activation involved approximately 41% of the atrium surface in Acomys. Cholinergic stimulation caused pronounced suppression of automaticity and changed the activation pattern of the pacemaker myocardium.
