Special Issue Information

Dear Colleagues,

Metals play a crucial role in cancer biology, influencing both tumorigenesis and cancer progression through various biochemical pathways. Essential trace elements such as zinc, copper, and iron are involved in key cellular processes, including DNA synthesis, cell division, and oxidative stress regulation. However, an imbalance in metal homeostasis can contribute to cancer development. Elevated levels of copper, for instance, have been linked to increased angiogenesis and metastasis, while iron dysregulation can exacerbate the formation of reactive oxygen species (ROS), leading to DNA damage, genomic instability and ferroptosis.

Metals also participate in the metabolism of cancer cells, often enhancing their growth and survival during hypoxia and nutrient deprivation. Cancer cells often exhibit altered metal uptake and efflux mechanisms, which support their rapid proliferation and resistance to therapeutic agents. Moreover, certain metals, such as manganese, can activate oncogenic signaling pathways, promoting tumor growth and resistance to apoptosis.

Understanding the complex interactions between metals and cancer metabolism provides potential avenues for novel therapeutic strategies, including metal chelation therapies and metal-targeting drugs, for disrupting the metal-dependent pathways that sustain tumor growth and progression.

Background: The paired-box gene 6 (PAX6) is an important transcription factor in the central nervous system, mainly regulating the development and differentiation of embryonic eyes and the nervous system. PAX6 expression is significantly decreased in glioma, and the expression levels are closely related to glioma development and prognosis. Therefore, it is important to study and elucidate the biological function of PAX6 in glioma to further our understanding of the occurrence and development of glioma. Methods: This study focused on the expression and regulation of PAX6 and hypoxia-inducing factor (HIF-1α) and investigated the molecular mechanism of ferroptosis regulated by PAX6 and HIF-1α. Firstly, immunohistochemistry, qPCR, Western blot, and other methods were used to detect PAX6 and HIF-1α expression in glioma tissues and cells, as well as the specific way in which PAX6 regulates HIF-1α. Then, some relative indicators of ferroptosis regulated by PAX6 in glioma were studied. Results: The results showed that PAX6 inhibited HIF-1α expression by regulating the levels of reactive oxygen species (ROS); overexpression of PAX6 promoted the expression of ROS and lipid peroxides (LPOs) in glioma cells and decreased the expression of intracellular antioxidant systems glutathione peroxidase 4 (GPX4) and glutathione (GSH). Conclusions: Downregulation of PAX6 plays an important role in regulating ferroptosis in glioma cells. Our research provides a reference basis for a deeper understanding of the role of PAX6 in ferroptosis of glioma. Full article
