Phosphorylation of KRT8 (keratin 8) by excessive mechanical load-activated PKN (protein kinase N) impairs autophagosome initiation and contributes to disc degeneration
This study validates a protective role of Krt8 during overloading-induced IDD and demonstrates that targeting overloading activation of PKNs could be a novel and effective approach to mechano stress-induced pathologies with a wider window of therapeutic opportunity.Abbreviations: AAV: adeno-associated virus; AF: anulus fibrosus; ANOVA: analysis of variance; ATG: autophagy related; BSA: bovine serum albumin; cDNA: complementary deoxyribonucleic acid; CEP: cartilaginous endplates; CHX: cycloheximide; cKO: conditional knockout; Cor: coronal plane; CT: computed tomography; Cy: coccygeal vertebra; D: aspartic acid; DEG: differe...

Nrf2/PINK1-mediated mitophagy induction alleviates sodium fluoride-induced hepatic injury by improving mitochondrial function, oxidative stress, and inflammation
Ecotoxicol Environ Saf. 2023 Feb 13;252:114646. doi: 10.1016/j.ecoenv.2023.114646. Online ahead of print.ABSTRACTMitophagy has distinct functions, which can lead to either protection or damage of tissues. Though current evidence indicated that NaF triggers mitophagy, the role and regulation of mitophagy in sodium fluoride (NaF)-induced liver injury still remain unclear. Therefore, we exployed the cell and mouse models and confirmed that NaF treatment activates mitophagy. Knocking down PTEN-induced putative kinase protein 1 (PINK1) expression attenuated mitophagy and increased the degree of mitochondrial impairment, oxidati...

siRNA high throughput screening identifies regulators of chloropicrin and hydrogen fluoride injury in human corneal epithelial cell models
Exp Eye Res. 2022 Jul 9:109169. doi: 10.1016/j.exer.2022.109169. Online ahead of print.ABSTRACTCorneal injuries induced by various toxicants result in similar clinical presentations such as corneal opacity and neovascularization. Many studies suggest that several weeks post-exposure a convergence of the molecular mechanisms drives these progressive pathologies. However, chemical agents vary in toxicological properties, and early molecular responses are anticipated to be somewhat dissimilar for different toxicants. We chose 3120 targets from the Dharmacon Human Druggable genome to screen for chloropicrin (CP) and hydrogen f...

Sodium fluoride activates the extrinsic apoptosis via regulating NOX4/ROS-mediated p53/DR5 signaling pathway in lung cells both in vitro and in vivo
In this study, we report that death receptor 5 (DR5), a major component of the extrinsic apoptotic pathway, is markedly induced upon NaF stimulation. Enhanced DR5 induction was necessary for the apoptotic effects of NaF, inasmuch as transfected BEAS-2B cells with DR5 siRNA attenuated NaF-induced caspase-8 activation in lung cells. Mechanism investigation indicated that the induction of DR5, following NaF exposure, was mediated by tumor protein 53 (p53)-dependent transcriptional activation. Notably, we demonstrated that NaF could induce a significant increase in intracellular reactive oxygen species (ROS) level derived from...

AMPK/p38/Nrf2 activation as a protective feedback to restrain oxidative stress and inflammation in microglia stimulated with sodium fluoride.
In conclusion, these data demonstrated for the first time that Nrf2 activation exerts a neuroprotective effect on NaF-stimulated redox imbalance and inflammation that is dependent on the AMPK/p38 pathway. PMID: 31837563 [PubMed - indexed for MEDLINE]
