Glaucoma is a group of diseases characterized by the degeneration of retinal ganglion cells (RGCs) and progressive, irreversible vision loss. High intraocular pressure (IOP) heightens the likelihood of glaucoma and correlates with RGC loss. While the current glaucoma therapy prioritizes lower the IOP; however, RGC, and visual loss may persist even when the IOP is well-controlled. As such, discovering and creating IOP-independent neuroprotective strategies for safeguard RGCs is crucial for glaucoma management. Investigating and clarifying the mechanism behind RGC death to counteract its effects is a promising direction for glaucoma control. Empirical studies of glaucoma reveal the role of multiple regulated cell death (RCD) pathways in RGC death. This review delineates the RCD of RGCs following IOP elevation and optic nerve damage and discusses the substantial benefits of mitigating RCD in RGCs in preserving visual function.

Type II nuclear receptors (T2NRs) require heterodimerization with a common partner, the retinoid X receptor (RXR), to bind cognate DNA recognition sites in chromatin. Based on previous biochemical and overexpression studies, binding of T2NRs to chromatin is proposed to be regulated by competition for a limiting pool of the core RXR subunit. However, this mechanism has not yet been tested for endogenous proteins in live cells.

Mesenchymal stem cells (MSCs) are a class of protocells that can differentiate into various cell types and have robust replication and renewal capabilities. MSCs secrete various nutritional factors to regulate the microenvironment of tumor tissues. The mechanism by which they inhibit or promote tumor growth may be closely related to MSC-derived exosomes (MSC-Exo).

Lung cancer progression is characterized by intricate epigenetic changes that impact critical metabolic processes and cell death pathways. In this study, we investigate the role of histone lactylation at the AIM2 locus and its downstream effects on ferroptosis regulation and lung cancer progression. We utilized a combination of biochemical assays, including chromatin immunoprecipitation (ChIP), quantitative real-time PCR (qRT-PCR), and western blotting to assess histone lactylation levels and gene expression.
