Amyotrophic lateral sclerosis(ALS)is a progressive neurodegenerative disorder characterized by the degeneration of motor neurons in the brain and spinal cord,leading to muscle weakness,paralysis,and ultimately death(Cleveland and Rothstein,2001).Frontotemporal lobar degeneration(FTLD)is a neurodegenerative disease affecting the frontal and temporal lobes of the brain,leading to changes in behavior,personality,and language(van Langenhove et al.,2012).Both ALS and FTLD are classified as proteinopathies in which abnormal protein aggregation and accumulation in neurons contribute to the disease *** in sarcoma(FUS)is a DNA/RNA-binding protein involved in various cellular processes,including transcriptional regulation,RNA splicing,and DNA *** in the FUS gene have been linked to familial ALS,highlighting the importance of FUS in the disease pathogenesis(vance et al.,2009).In ALS and FTLD,aberrant post-translational modifications(PTMs)of FUS,such as phosphorylation,acetylation,and methylation,have been implicated in the promotion of FUS aggregation and neurotoxicity(Choi et al.,2023).Therefore,understanding the regulatory mechanisms of FUS PTMs is crucial for developing targeted therapies against these diseases.

This study aims to evaluate the effect of serum concentration, synchronization time, and confluence degree on the synchronisation efficiency of goat fibroblast cycle. The results indicated that there was no difference in the percentage of nucleated fibroblasts in the G0/G1 stage between serum concentrations of 0.3% and 0.4% (83.89% and 82.69%, respectively, P > 0.05) as well as between serum concentrations of 0.2% and 0.5% (76.95% and 75.46%, respectively, P > 0.05). The percentage of nucleated fibroblasts in the G0/G1 stage was highest at the concentration of 0.3% and lowest in the control group (83.89% vs. 62.67%, P 0.05). The beneficial effect of high confluence was confirmed by the large percentage of nucleated fibroblasts at the G0/G1 stage. The 60% confluency was significantly lower than the 80% and 100% confluency (73.44%, 86.63%, and 87.17%, respectively, P < 0.05). The results indicate that the goat fibroblast cycle synchronization is the most effective at the serum concentration of 0.3%, 72 hours of synchronization and 100% confluency.

协同创新共同体建设遇到的最大困难是跨区域协同治理问题,可以说治理机制是否有效直接决定跨区域协同创新效果。建设欧洲研究区是欧盟促进其成员国间跨区域协同创新的重要举措,目标是整合成员国创新资源和力量以提升欧盟整体创新竞争力。欧盟成员国创新能力不平衡,为实现各国有效跨区域协同治理,欧盟搭建了欧盟及其成员国和地区多层治理下的共同治理框架,通过设立欧洲研究区咨询建议机构、注重决策的民主化形成政策咨询建议机制,通过编制《欧洲研究区发展报告》《欧洲研究区发展路线图》和纳入“欧洲学期”构建监督机制,并开发基金工具、项目工具和各种对话机制等治理工具,在成员国间建立创新伙伴关系,推进各国创新资源、项目和政策的协同,提升欧盟治理能力、改善欧盟创新系统失灵问题。欧洲研究区加强创新能力发展不平衡地区间协同创新治理方面的经验对中国跨区域协同创新共同体建设,在加强不同层级主体共同治理、形成有效咨询建议机制、设计多种互补治理工具等方面带来有益启示。
