Therapeutic potential of ASK1 activators in cancer treatment: Current insights and future directions

Apoptosis signal-regulated kinase 1 (ASK1) is a member of the mitogen-activated protein kinase kinase (MAP3K) family, whose activation and regulation are intricately associated with apoptosis. ASK1 is activated in response to oxidative stress, among other stimuli, subsequently triggering downstream JNK, p38 MAPK, and mitochondria-dependent apoptotic signaling, which participate in the initiation of tumor cell apoptosis induced by various stimuli. Research has shown that ASK1 plays a crucial role in the apoptosis of lung cancer, breast cancer, and liver cancer cells. Currently, the investigation of effective ASK1 activators is a hot topic in research on tumor cell apoptosis. Synthetic compounds such as human β-defensin, triazolothiazide derivatives and heat shock protein 27 inhibitors; natural compounds such as quercetin, Laminarina japonica polysaccharide-1 peptide and theabrownin; and nanomedicines such as cerium oxide nanoparticles, magnetite FeO nanoparticles and silver nanoparticles can activate ASK1 and induce apoptosis in various tumor cells. This review extensively investigates the roles and activation mechanisms of ASK1, explores its impact on a variety of apoptotic signaling pathways, and discusses the potential therapeutic applications of various ASK1 activators in cancer treatment. In addition, this paper provides an in-depth discussion of the future development of this field and proposes a promising method for further research and clinical progress.

Importance of Certain Varieties of Cucurbits in Enhancing Health: A Review

The Cucurbitaceae family is an extensive group of fruits and vegetables that exhibit common characteristics; for example, they are farmed on a global scale and exhibit a wide range of applications, including fresh consumption and use in various food and beverage products. As is frequent, many species or genera share a common name, and this can lead to some confusion when looking for information about a specific variety. In this review, we describe the findings about the biological activity, like antibacterial, antiviral, antidiabetic, and anticancer properties, of two genera of this family, Cucumis and Momordica, which have been characterized and evaluated in several research studies and regarding which information is readily accessible. Those activities rely on the various physicochemical qualities and nutritional content of each variety, including factors like β-carotene and polyphenols, among others. The goal of this review is to provide a rapid search for each activity examined in the literature, enabling future research on their potential uses in functional foods and nutraceutical supplements.
