Summary: The study found that cytosolic mtDNA regulates odontoblast inflammation through GSDMD-mediated pyroptosis, while STING-dependent inflammation may serve as a compensatory mechanism to control GSDMD-mediated pyroptosis, promoting the immune inflammatory response. These findings provide important clues to understand the role of mtDNA-GSDMD-STING in regulating odontoblast inflammation.

Summary: Ubiquitin phosphorylation by PINK1 is crucial for mitophagy and potential PD treatments. N (6)-substituted adenosines, like kinetin riboside and N (6)-benzyladenosine, activate PINK1 and induce mitophagy in cells. Moreover, these adenosines can inhibit elevated ubiquitin phosphorylation induced by mitochondrial depolarizing agents.

Summary: This study elucidated the mechanism by which M95 affects cell death induced by rabies virus infection. Ni-CE strain induced DNA fragmentation, cell membrane disruption, PS exposure, caspase-3/7 activation, and PARP-1 cleavage, while Nishigahara strain induced PS exposure but not other apoptosis-related features. The data suggest that M95 mutation-related cell death involves both caspase-dependent and -independent pathways.

Summary: The interaction of KRAS with the plasma membrane is primarily determined by electrostatics, but also extends to different phosphatidylserine species and acyl chain compositions. Different prenylated PBD-bilayer interactions exhibit distinct patterns, leading to differential responses to various membrane perturbations, ultimately reflecting the behavior of preferred phosphatidylserine ligands.

Summary: This study aims to clarify the mechanisms underlying HEMA-induced cytotoxicity and apoptosis in macrophages. The results showed that HEMA induced concentration-dependent cell toxicity and mediated genotoxicity and apoptosis through mitochondrial dysfunction, intrinsic caspase pathway activation, and intracellular reactive oxygen species accumulation.

Summary: This study investigated the anti-neoplastic activity of phosphanegold (I) thiolates 1-3 against MCF-7 cells and explored their apoptosis-inducing ability. The compounds exhibited better cytotoxicities than cisplatin and were found to promote ROS generation, cytochrome c release, and activation of caspases on MCF-7 cells.

Summary: This research investigates the anti-proliferation and apoptosis-inducing effects of nine cultivars of lupin seeds on colon cancer cells. The findings demonstrate that lupin cultivars can arrest cell cycles by inducing increased generation of intracellular reactive oxygen species and activation of caspases-3/7.

Summary: Inhibiting CypD activity with novel non-immunosuppressive cyclophilin inhibitors (SMCypIs) can effectively reduce procoagulant platelet formation and provide a promising strategy for limiting thrombosis without affecting normal platelet function.

Summary: The study found that modeled microgravity alters the apoptotic cell death process induced by beneficial microbes, by increasing the activity of caspases. However, this increase can be mitigated by using caspase inhibitors, which may have implications for maintaining animal-microbial homeostasis in spaceflight.

Summary: The new series of EGFR inhibitors showed promising antiproliferative activity against cancer cell lines, with para-substituted phenethyl derivatives displaying superior activity. Some compounds also exhibited potential EGFR inhibitory activity, modulation of apoptosis-related proteins, and cell cycle arrest effects.

Summary: Caspases are important proteases involved in cellular events such as apoptosis and inflammation. They also have non-apoptotic pro-survival functions, which are crucial in processes like cell proliferation, differentiation, and migration, as well as tumor metastasis and chemotherapy resistance. Understanding the mechanisms that regulate caspase activities is important for both mechanistic and clinical purposes. Additionally, the functions of apoptotic caspases are affected by various post-translational modifications.

Summary: Loss of neurons in chronic neurodegenerative diseases occurs over a period of many years. However, it is unclear at which point neuronal cell death becomes irreversible. This study found that the release of Cyto.C is a marker of the point of no return, while other phenotypic changes could still be reversed.

Summary: The study revealed that DEK, regulated by miR-489-3p, is induced in spinal dorsal horn neurons after spinal nerve ligation (SNL). DEK recruits TET1 to promote the transcription of specific genes in the dorsal horn, contributing to neuropathic allodynia. Inhibiting miR-489-3p expression attenuated allodynia behavior, suggesting a potential target for treating neuropathic allodynia.

Summary: The neurohormone melatonin shows promising potential in alleviating neuropathic pain caused by chemotherapy, with its analgesic effects mediated through melatonin receptor 2. Multiple administrations of melatonin during chemotherapy may be more effective in relieving allodynia/hyperalgesia and inhibiting the epigenetic program in neurons compared to a single administration after chemotherapy.
