- Ischemic stroke remains a leading cause of death and disability, yet effective pharmacological neuroprotection remains elusive. ROS-induced PARthanatos-driven by PARP1 hyperactivation and the mitochondrial-apoptosis-inducing factor (AIF) death axis-is a principal executor of ischemic neuronal death. However, direct PARP1 inhibition inevitably compromises essential DNA repair. Here, we identify a downstream intervention node that uncouples lethal signaling from genomic maintenance. Through phenotype-to-target deconvolution combining reverse pharmacophore mapping, bioinformatic intersection with programmed cell death genes, and integrated biophysical validation (docking, 100-ns molecular dynamics, cellular thermal shift assay, and surface plasmon resonance), we demonstrate that wogonoside (WS), a flavonoid glycoside from Scutellaria baicalensis, directly binds death-associated protein kinase 1 (DAPK1; KD = 6.07 μM) and acts as a ligand-induced degrader that triggers proteasome-dependent DAPK1 clearance. CRISPR/Cas9-mediated DAPK1 knockout fully phenocopied WS-mediated protection, whereas ectopic DAPK1 overexpression abolished it. WS-induced degradation intercepted the JNK-mitochondrial depolarization-AIF nuclear translocation cascade while leaving PARP1 catalytic activity, PAR polymer formation, and γH2AX resolution fully intact-in stark contrast to the clinical PARP1 inhibitor olaparib. In a mouse permanent distal middle cerebral artery occlusion model, a single dose of WS reduced cortical infarct volume by ∼50%, preserved neurons, suppressed microglial activation, and maintained microvascular integrity, accompanied by significant sensorimotor recovery. Single-nucleus RNA sequencing revealed Dapk1 enrichment in activated microglia and co-variation with neuronal MAPK pro-death signaling, suggesting a dual-compartment mechanism. These findings define proteasome-dependent DAPK1 degradation as a mechanistically distinct antioxidant strategy for acute ischemic stroke. - Source: PubMed

Zhai Chun-ZeCao YinShen Yu-XinWang Yi-ZheLiu Zhi-PengLiu FangYu Jin-LiuWang Xiu-XiuZhang Zhao-HuanXu Xiao-Hui - Metastasis and associated therapy resistance remain the principal drivers of cancer related death, and there is a pressing need for a deeper mechanistic understanding and anti-metastatic therapies. For patients that suffer from hepatocellular carcinomas (HCCs), which are the most common primary liver cancers, frequent systemic metastasis results in bleak 5-year survival prognoses of only 4%. To metastasize, carcinoma cells must acquire an invasive phenotype, which typically requires switching from an epithelial-like apical-basal polarity to the front-rear polarity of mesenchymal-like cells. Signaling cues that originate in the tumor microenvironment can activate cellular morphogenic programs that drive polarity switching, like the epithelial-mesenchymal transition (EMT). Protein kinases control most cell signaling pathways and are highly actionable drug targets; however, systematic studies determining the kinases that underly the epithelial-mesenchymal polarity switch (EMPS) are lacking. We developed an assay platform that integrates mass spectrometry (MS)-based kinome profiling, broadly capturing kinase network activity, with chemical genetic screening using selective kinase inhibitors and quantitative phase imaging (QPI), serving as the phenotypic readout. Applying this approach that we dubbed morphokin-MS, to epithelial-like HCC cell lines that we induced to undergo EMPS identified a conserved network of 12 kinases that contributed to HCC cell polarity switching and directed cell migration; MS-based kinome profiling of 17 HCC patient tumors showed that these kinase are frequently upregulated in human tumors. morphokin-MS also revealed that death-associated protein kinase 3 (DAPK3) is one of the principal drivers of the EMPS and directed HCC cell migration. Thus, our mechanistic studies revealed that DAPK3 forms a complex with DAPK1 and filamin-A inter-acting protein 1-like (FILIP1L), which act as scaffold proteins that recruit DAPK3 to the centrosome. Pharmaco-logical and genetic inhibition of the DAPK1-DAPK3-FILIP1L complex blocked centrosome repositioning and microtubule polarization toward the leading edge of mesenchymal-like HCC cells, directed cell migration, and invasion. Our morphokin-MS method and comprehensive kinome profiling data will serve as a valuable resource for the cancer research community; our discovery of an inducible mesenchymal-like DAPK1-DAPK3-FILIP1L polarity complex that controls centrosome positioning in motile HCC cells may lead to the development of novel therapeutics for combatting cancer metastasis. - Source: PubMed

Rantso Thankhoe AWoods KathrynJensen PaigeWalker Katie AChan Alexandria MMaguire Kathleen MZitnay Rebecca GLovely Lotfa HYang JingshuTakyi AugustineStewart PaulEvason KimberleyJudson-Torres Robert LGolkowski Martin - We previously demonstrated that apolipoprotein E (apoE4) accelerates neurodegeneration in a transgenic mouse model, but the mechanism is still unclear. A previous study reported that death-associated protein kinase 1 (DAPK1) interacts with the NR2B subunit of the N-methyl-D-aspartate (NMDA) receptor, this DAPK1-NR2B interaction increases calcium intake in cells, leading to cell damage. As apoE4 is the strongest genetic risk factor for sporadic Alzheimer's disease (sAD) and calcium dyshomeostasis is a key driver of sAD-related neurotoxicity, the unclear mechanism linking apoE4 to calcium imbalance remains a critical gap in developing targeted therapies for sAD. Addressing this gap is urgent to advance our understanding of sAD pathogenesis and identify new therapeutic targets. Our study aimed to determine whether the neurotoxic effects of apoE4 are mediated by the interaction between DAPK-1 and the NMDA receptor NR2B subunit. - Source: PubMed
