    • 摘要: Axon regeneration of central neurons is a complex process that is tightly regulated by multiple extrinsic and intrinsic factors.The expression levels of distinct genes are changed after central neural system(CNS)injury and affect axon regeneration.A previous study identified dusp2 as an upregulated gene in zebrafish with spinal cord injury.Here,we found that dual specificity phosphatase 2(DUSP2)is a negative regulator of axon regeneration of the Mauthner cell(M-cell).DUSP2 is a phosphatase that mediates the dephosphorylation of JNK.In this study,we knocked out dusp2 by CRISPR/Cas9 and found that M-cell axons of dusp2(-/-)zebrafish had a better regeneration at the early stage after birth(within 8 days after birth),while those of dusp2^(+/-)zebrafish did not.Overexpression of DUSP2 in Tg(Tol 056)zebrafish by single-cell electroporation retarded the regeneration of M-cell axons.Western blotting results showed that DUSP2 knockout slightly increased the levels of phosphorylated JNK.These findings suggest that knocking out DUSP2 promoted the regeneration of zebrafish M-cell axons,possibly through enhancing JNK phosphorylation.

    • 摘要: Objective:Protein convertase subtilisin/Kexin type 9(PCSK9)has been found to be closely associated with the occurrence and development of numerous tumors.However,the precise role of PCSK9 and its relationship to the development of hepatocellular carcinoma(HCC)remain largely unknown.This study aimed to clarify these issues.Methods:The expression levels of PCSK9 in HCC tissues and HCC cell lines were determined by the quantitative reverse transcription polymerase chain reaction,Western blot,and immunohistochemical analyses,and the effects of PCSK9 expression on HCC cell biological traits were investigated by overexpressing and downregulating PCSK9 expression in vivo and in vitro.Additionally,the mechanism by which PCSK9 mediated dissociation of glutathione S-transferase Pi 1(GSTP1)dimers and phosphorylation of the Jun N-terminal kinase(JNK)pathway components were investigated.Results:PCSK9 expression levels were significantly lower in HCC tissues than in adjacent non-tumor samples.In vivo and in vitro experiments suggested that PCSK9 inhibited HCC cell proliferation and metastasis.Further analysis showed that PCSK9 interacted with GSTP1 and promoted GSTP1 dimer dissociation and JNK signaling pathway inactivation in HCC cells.Moreover,the relationships between PCSK9 protein expressions and clinical outcomes were investigated.The PCSK9-lo group displayed a significantly shorter overall survival(OS;median OS:64.2 months vs.83.2 months;log-rank statistic:4.237;P=0.04)and recurrencefree survival(RFS;median RFS:26.5 months vs.46.6 months;log-rank statistic:10.498;P=0.001)time than the PCSK9-hi group.Conclusions:PCSK9 inhibited HCC cell proliferation,cell cycle progression,and apoptosis by interacting with GSTP1 and suppressing JNK signaling,suggesting that PCSK9 might act as a tumor suppressor and be a therapeutic target in HCC patients.

    • 摘要: Objective:To demonstrate the effect of dieckol from Eisenia bicyclis on osteoclastogenesis using RAW 264.7 cells.Methods:Murine macrophage RAW 264.7 cells were subjected to dieckol treatment,followed by treatment with receptor activator of nuclear factor kappa-B ligand(RANKL)to induce osteoclastogenesis.Tartrate-resistant acid phosphatase(TRAP)activity was examined using a TRAP activity kit.Western blotting analysis was conducted to examine the level of osteoclast-related factors,including TRAP and calcitonin receptor(CTR),transcriptional factors,including c-Fos,c-Jun,and nuclear factor of activated T cells cytoplasmic 1(NFATc1),nuclear factor kappa-B(NF-κB),extracellular signal-regulated kinase(ERK),and c-Jun N-terminal kinase(JNK).Immunofluorescence staining was conducted to examine the expression of c-Fos,c-Jun,and NFATc1.Results:Among the four phlorotannin compounds present in Eisenia bicyclis,dieckol significantly hindered osteoclast differentiation and expression of RANKL-induced TRAP and CTR.In addition,dieckol downregulated the expression levels of c-Fos,c-Jun,NFATc1,ERK,and JNK,and suppressed NF-κB signaling.Conclusions:Dieckol can suppress RANKL-induced osteoclastogenesis.Therefore,it has therapeutic potential in treating osteoclastogenesis-associated diseases.

    • 摘要: 背景:骨稳态的维持主要依赖于破骨细胞与成骨细胞之间的协同作用,丝裂原活化蛋白激酶介导的自噬对破骨细胞增殖、分化、功能的影响很有可能会破坏骨稳态平衡,从而影响组织工程的骨重建工作。目的:通过目前已有的实验研究和临床资料分析丝裂原活化蛋白激酶介导的自噬对破骨细胞的影响。方法:计算机检索中国知网、万方医学网、PubMed数据库中的相关文献,检索时间从建库截止至2020-06-31,中文检索词为“丝裂原活化蛋白激酶,破骨细胞,自噬”,英文检索词为“mitogen-activated protein kinase,ERK,p38,JNK,osteoclast,autophagy”。结果与结论:①丝裂原活化蛋白激酶既可以单独介导自噬对破骨细胞产生影响,也可以同时激活其他信号通路共同介导自噬;②细胞外信号调节激酶(ERK)通路介导的自噬常伴随着Ca^(2+)的参与,主要影响破骨细胞的分化和功能;③c-Jun氨基末端激酶(JNK)主要通过与Beclin-1的共同作用影响破骨细胞的成熟和分化;④p38激酶自噬具有促进和抑制的双向作用,从而影响破骨细胞的增殖与分化。
