CELL SORTING IN THE PRESENCE OF CYTOCHALASIN B [PDF]

open access: yesThe Journal of Cell Biology, 1972
The ability of cytochalasin B to inhibit ruffled membrane activity and cellular locomotion of vertebrate cells in monolayer culture prompted its use to study the necessity for this kind of active cellular locomotion in cell sorting in heterotypic cell aggregates.

Gelsolin's Protective Role in MASH through F‐Actin Regulation and P53 Degradation

open access: yesAdvanced Science, EarlyView.
Gelsolin (GSN) maintains liver metabolic homeostasis by promoting MDM2‐mediated P53 degradation and inhibiting F‐actin/Yes‐associated protein (YAP) overactivation. Loss of GSN impairs P53 degradation, increases lipid deposition, and enhances YAP‐driven fibrosis and inflammation in metabolic‐associated steatohepatitis.

Annexin A3 Represses Endothelial Permeability and Inflammation During Sepsis via Actin Cytoskeleton Modulation

open access: yesAdvanced Science, EarlyView.
Annexin A3 (ANXA3) plays an endogenous protective role in endothelial dysfunction in sepsis by stabilizing the actin cytoskeleton, modulating cell permeability, and inhibiting pATF2/CD62E inflammatory signaling. Abstract Increased endothelial permeability and a dysregulated inflammatory response play key roles in organ damage in sepsis.

Mycotoxins: Producing Fungi and Mechanisms of Phytotoxicity

open access: yesAgriculture, 2015
Mycotoxins are secondary fungal metabolites, toxic to humans, animals and plants. Among the hundreds of known mycotoxins, aflatoxins, citrinin, patulin, penicillic acid, tenuazonic acid, ochratoxin A, cytochalasins, deoxynivalenol, fumonisins, fusarin C,

Differences in protein mobility between pioneer versus follower growth cones [PDF]

open access: yes, 2007
Navigating growth cones need to integrate, process and respond to guidance signals, requiring dynamic information transfer within and between different compartments.

Inhibition and Rescue of Hyperglycemia‐Induced Cellular Senescence by Mitochondrial Transfer from Enucleated Mesenchymal Stem Cell‐Derived Microvesicles for Chronic Wound Healing

open access: yesAdvanced Science, EarlyView.
This study develops enucleated MSC‐derived microvesicles (Mito@euMVs) to deliver functional mitochondria for optimizing wound repair. By efficiently encapsulating mitochondria, Mito@euMVs rejuvenate hyperglycemia‐induced senescent fibroblasts and HUVECs. Using PVA microneedle patches, the therapeutic efficacy of Mito@euMVs is validated in diabetic rats

UTX Responds to Nanotopography to Suppress Macrophage Inflammatory Response by Remodeling H3K27me3 Modification

open access: yesAdvanced Science, EarlyView.
Compared with those on the pTi surface, macrophages on the TNTs surface present reduced myosin II contractility, which facilitates the nuclear translocation of the UTX. This reduction decreases the enrichment of the repressive H3K27me3 histone modification at the Abca1 gene locus, which promotes the transcription and protein expression of ABCA1 ...

Secretion of soluble-form CD93 from human endothelial progenitor cells [PDF]

open access: yes, 2015
ヒト血管内皮前駆細胞(Human endothelial progenitor cells :HEPCs)から分泌される可溶性CD93(sCD93)分子の動態を自主開発した抗ヒトCD93 抗体(mNI-11)を用いて解析した。HEPCs は低濃度であるが、sCD93 分子を培養液中に自然分泌していることがわかった。HEPCs をPKC 活性剤であるPMAで処理したところ、sCD93 分子の分泌は有意に増強した(P < 0.01)。また、PMA 処理の初期段階からsCD93 分泌の増強は認められた。次に ...

Cortical Actin Turnover during Cytokinesis Requires Myosin II [PDF]

open access: yes, 2005
SummaryThe involvement of myosin II in cytokinesis has been demonstrated with microinjection, genetic, and pharmacological approaches; however, the exact role of myosin II in cell division remains poorly understood.

Construction of Active Sites‐Accessible Au8 Clusters for Intensive Tumor Pyroptosis

open access: yesAggregate, EarlyView.
Ethynylferrocene (EFc) was utilized to engineer molecular‐like gold nanoclusters (NCs) with accessibly catalytic centers, resulting in NCs exhibiting excellent peroxidase‐like activity and the ability to radiosensitize, leading to the production of intracellular oxidative stress and activation of pyroptosis.
