Ganoderma mushrooms have a variety of pharmacological activities and may have antitumor effects. Therefore, the antitumor activity of the methanolic fruiting body extracts of three Ganoderma spp. will be evaluated by estimating cell viability, cell cycle parameters and the mode of cellular death.

Ferroptosis is a unique cell death mode that relies on iron and lipid peroxidation (LPO) and is extensively utilized to treat drug-resistant tumor. However, like the other antitumor model, requirement of oxygen limited its application in treating the malignant tumors in anaerobic environments, just as photodynamic therapy, a very promising anticancer therapy. Here, we show that an iridium(III) complex (Ir-dF), which was often used in proton-coupled electron transport (PCET) process, can induce efficient cell death upon photo irradiation, which can be effectively protected by the typical ferroptosis inhibitor Fer-1 but not by the classic iron chelating agents and ROS scavengers.

Background: Melanoma is a highly lethal form of skin cancer, and effective treatment remains a significant challenge. SPP86 is a novel potential therapeutic drug. Nonetheless, the specific influence of SPP86 on autophagy, particularly its mechanisms in the context of DNA damage and apoptosis in human melanoma cells, remains inadequately understood.

Betulinic acid and other herbal pentacyclic triterpenes have attracted interest in cancer research as these natural products induce apoptosis and suppress tumor progression. However, the molecular basis of the antitumor effect is still unknown. Here we show that monophthalates of betulinic acid and related triterpenes inhibit GDP/GTP exchange in oncogenic K-RAS4B proteins the PI3K/AKT downstream cascade.
