  Antitumor activity of scorpion venom-derived peptides: A meta-analysis of preclinical studies Abstract Despite advances in cancer therapeutics, there are still challenges in improving drug toxicity and selectivity. Peptides from various venous species have recently garnered attention for their biopharmaceutical potential, particularly in cancer. The present study aimed to conduct a meta-analysis of the antitumor activity of scorpion venom-derived peptides (SVDPs) previously reported in preclinical models. The bibliographic research included original and review articles written in English published from 2015 to 2026. Studies within the scope were retrieved from the EBSCO Discovery Service, PubMed, and WIPO databases. A total of 27 articles that met the inclusion and exclusion criteria were included in this research, and the collected data were synthesized through a meta-analysis. In the included in vitro and in vivo studies, the effect of SVDPs on breast/mammary gland, cervical,...

Transcriptomics-Informed Proteomics of Venom Glands and Crude Venom from Tityus cf. Asthenes from Panama: Enzymes, Proteins, Toxins, and Antimicrobial Peptides

Abstract

The venom gland and the crude venom of Tityus cf. asthenes were analyzed by transcriptomic and proteomic methods. High-throughput RNA sequencing (RNA-seq) and mass spectrometry (MS/MS) allowed for the identification of a wide range of venom proteins. Notably, transcriptomic and proteomic venom approaches identified a hyaluronidase, toxins that affect the voltage-gated Na+ channels, LVPs, cysteine-rich secretory proteins, metalloproteinases, serine proteases, alpha-amylases, toxins that affect the voltage-gated K+ channel, scorpion calcin-like, single insulin-like growth factor-binding domain proteins, nondisulfide-bridged peptides, lectins, chitinases, Kunitz-type serine protease inhibitors, cyclotide trypsin inhibitors, and uncharacterized proteins. These newly identified components enhance the understanding of the venomous nature of Tityus cf. asthenes.
