Emerging trends of phytochemicals as ferroptosis modulators in cancer therapy

Ferroptosis, a novel form of regulated cell death characterized by dependence on iron and lipid peroxidation, has been implicated in a wide range of clinical conditions including neurological diseases, cardiovascular disorders, acute kidney failure, and various types of cancer. Therefore, it is critical to suppress cancer progression and proliferation. Ferroptosis can be triggered in cancer cells and some normal cells by synthetic substances, such as erastin, Ras-selective lethal small molecule-3, or clinical pharmaceuticals. Natural bioactive compounds are traditional drug discovery tools, and some have been therapeutically used as dietary additives or pharmaceutical agents against various malignancies. The fact that natural products have multiple targets and minimal side effects has led to notable advances in anticancer research. Research has indicated that ferroptosis can also be induced by natural compounds during cancer treatment. In this review, we focused on the most recent developments in emerging molecular processes and the significance of ferroptosis in cancer. To provide new perspectives on the future development of ferroptosis-related anticancer medications, we also provide a summary of the implications of natural phytochemicals in triggering ferroptosis through ROS production and ferritinophagy induction in a variety of malignancies.

Anticancer Effect of Ruscogenin in B(a)P-Induced Lung Cancer in Mice via Modulation of Proinflammatory Cytokines and Mitochondrial Enzymes

Lung cancer, one of the most often diagnosed malignancies, is the top cause of death in both men and women globally. In both developed and emerging countries, high incidences of cancer are becoming a huge health burden. Natural resources, including plants, have always been a possible source of lead compounds in the identification of optimal medications for cancer treatment, with natural resources accounting for around half of all anticancer drugs. Ruscogenin, a natural saponin, is a major component of Radix Ophiopogon japonicus with a well-established anticancer activity. In this study, the anticancer potential of ruscogenin against a B(a)P-challenged lung cancer model in mice was assessed. The mice were categorized into four groups: group I was as the control group, group II mice were challenged with B(a)P, group III rodents were treated with ruscogenin prior to challenge with B(a)P, and group IV rodents were treated with ruscogenin after B(a)P administration. Tumor incidence was calculated, and the following parameters were analyzed: body weight, lung weight, immunoglobulin (Ig) levels (IgG, IgA, and IgM), key marker enzymes, and proinflammatory cytokines in both treated and control mice. Lung tissues were analyzed via histopathological analysis. According to our results, all the markers that favor the growth of cancer were increased in the lung cancer group. After administration of ruscogenin, all the markers returned to their original levels, revealing the anticancer potential of ruscogenin.
