Research is exploring the role of O-GlcNAcylation in regulating various forms of programmed cell death, including ferroptosis, pyroptosis, and necroptosis. This area of study is examining the molecular crosstalk between different cell death mechanisms and their potential therapeutic applications in diseases. The investigation is also delving into the relationship between cell death pathways and their impact on homeostasis, infection, inflammation, and tumorigenesis, including in specific types of cancer such as hepatocellular carcinoma.
