(Chan and Moris, 2006) . As reported by (Shah et al., 2014) classifications for BC have been created in an effort to treat patients more successfully. Triple-negative breast cancer (TNBC), is an extremely truculent subtype of BC (Zhu et al., 2023) . It is more common in young women compared to other BC subtypes, and it is linked to higher cancer risk and death (Dent et al., 2007) . On the surface of TNBC, there is no expression of the progesterone, estrogen, or HER2 receptors (Borri and Granaglia, 2021) . Considering this fact, TNBC represents a unique and challenging entity within BC due to its aggressive behavior, limited treatment options, and poorer prognosis compared to other subtypes (Wein and Loi, 2017) . Although chemotherapy is the main form of treatment for patients with TNBC, the effectiveness of chemotherapy for TNBC is still limited (Yi et al., 2021) .\u003Cbr>Animal poisons and venoms from a variety of species, including snakes, scorpions, cone snails, bees, and wasps, have been extensively researched overtime due to their potential as a significant source of bioactive chemicals (Harvey, 2014). A wealth of active | pharmacological proteins and peptides have been reported to be found in animal venoms (Mohamed et al., 2019) . For many years numerous studies have demonstrated the significant effect of cobra venom in providing relief from various types of pain, including that associated with cancer, neuralgia, and joint-related disorders (Liang et al., 2015) . Predominately snake venom comprises various polypeptide toxins and enzymes manifesting diverse pharmacological and biological activities contra virus, bacteria, and tumor (Salama et al., 2018; Roy and Bharadvaja, 2021) . Venom enzymes extracted from different snake species have recently been shown in a number of studies to have potential therapeutic benefits, and this has led to a growing interest in their application in the biomedical area (Cedro et al., 2018) .\u003Cbr>Furthermore, snake venom has been utilized in varied communities based on its ab","cbCaiabw2dxtec0t","https://ap.wps.com/l/cbCaiabw2dxtec0t","pdf",736392,11,"English","# Abstract\n## Background, Aim\n## Methods\n## Results, Conclusion\n# Introduction\n## Triple-negative breast cancer challenges\n## Snake venom bioactive mechanisms\n## Nanoparticle delivery for cancer therapy","[{\"question\":\"What is the study aiming to test?\",\"answer\":\"The study evaluates the anticancer effect of Naja haje venom, administered alone or loaded onto silica nanoparticles, against triple-negative breast cancer in vivo.\"},{\"question\":\"How were the experimental animals treated and analyzed?\",\"answer\":\"Rats were divided into five groups with different venom dose levels.
