A team of Indian researchers has produced the first comprehensive molecular and functional profile of the venom gland of Stegodyphus sarasinorum<\/i>, a colonial spider species found across the Indian subcontinent, to identify numerous\u00a0proteins and small molecules that could serve as promising leads for future drug discovery.<\/p>\n

Published in Springer Nature\u2019s peer-reviewed, open-access journal Scientific Reports<\/i>, the study identifies bioactive compounds associated with anti-cancer, antimicrobial and immune-related functions, while also demonstrating that venom gland extracts can kill cancer cells under laboratory conditions.<\/p>\n

The researchers caution, however, that the findings represent an early stage of biomedical research and require extensive validation before any clinical application becomes possible.<\/p>\n

Lead researcher A.P. Ajay Kumar of the Department of Zoology at Sree Neelakanta Government Sanskrit College, Pattambi, led the multidisciplinary study.<\/p>\n

Unlike most spiders, which are solitary hunters, S.\u00a0sarasinorum<\/i> lives in permanent colonies, constructs communal silk nests and captures\u00a0prey cooperatively. It is among only a small number of permanently social spider species known worldwide, thereby making it an important model for studying both spider behaviour and venom biology.<\/p>\n

Although spider venom has long attracted scientific interest for their diverse biological activities, this is the first study to comprehensively analyse the molecular composition of the venom gland of this species using an integrated multi-omics approach, the researchers emphasise.<\/p>\n

The research team combined transcriptomics, proteomics, metabolomics and Confocal Raman Spectroscopy to examine the spider\u2019s venom gland in great\u00a0detail. Their analysis identified 31 protein components through transcriptomic profiling and 32 proteins through proteomic analysis. In addition, Ultra High-Performance Liquid Chromatography-Mass Spectrometry (UHPLC-MS) detected 81 metabolites, including amino acids, biogenic amines and organic acids\u00a0to provide a detailed molecular inventory of the venom gland.<\/p>\n

To investigate the biological activity of these molecules, the researchers tested venom gland extracts against Dalton\u2019s Lymphoma Ascites (DLA) cancer cells in laboratory experiments. The extracts exhibited dose-dependent cytotoxicity, meaning that higher concentrations destroyed a greater proportion of cancer cells.<\/p>\n

The findings suggest that the venom gland contains molecules with anti-cancer potential, the experiments were conducted only in cultured cells. Nonetheless,\u00a0further studies involving additional cancer models, healthy cells, animals and eventually clinical trials will be required before any therapeutic use can be considered.<\/p>\n

Among the most significant discoveries was the identification of several protein families that are already known\u00a0for their biomedical relevance. These include hemocyanin proteins, which are known to stimulate immune responses and have attracted considerable interest in cancer immunotherapy research. The study also detected U12 and U20 lycotoxins, peptide molecules that can disrupt the membranes of bacteria and cancer cells, making them promising templates for the future development of antimicrobial peptides and targeted anti-cancer compounds.<\/p>\n

The experimental work was carried out by research scholar Veena Venugopal, with contributions from collaborators from Calicut University, S.N. College, Nattika, St. Joseph\u2019s College, Devagiri, PSG Institute of Advanced Studies, Coimbatore; GITAM University, Andhra Pradesh; and\u00a0Ajman University, UAE.<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
