Understanding gene expression variations between species is pivotal for deciphering the evolutionary diversity in phenotypes. Rhesus macaques(Macaca mulatta, MMU)and crab-eating macaques(M. fascicularis, MFA) serve as crucial nonhuman primate biomedical models with different phenotypes. To date, however, large-scale comparative transcriptome research between these two species has not yet been fully explored. Here, we conducted systematic comparisons utilizing newly sequenced RNA-seq data from84 samples(41 MFA samples and 43 MMU samples)encompassing 14 common tissues. Our findings revealed a small fraction of genes(3.7%) with differential expression between the two species, as well as 36.5% of genes with tissue-specific expression in both macaques. Comparison of gene expression between macaques and humans indicated that 22.6% of orthologous genes displayed differential expression in at least two tissues. Moreover,19.41% of genes that overlapped with macaque-specific structural variants showed differential expression between humans and macaques. Of these, the FAM220A gene exhibited elevated expression in humans compared to macaques due to lineage-specific duplication. In summary,this study presents a large-scale transcriptomic comparison between MMU and MFA and between macaques and humans. The discovery of gene expression variations not only enhances the biomedical utility of macaque models but also contributes to the wider field of primate genomics.

Since the emergence of graphene, transition metal dichalcogenides, and black phosphorus, two-dimensional materials have attracted significant attention and have driven the development of fundamental physics and optoelectronic devices. Metal phosphorus trichalcogenides(MPX3), due to their large bandgap of 1.3–3.5 eV, enable the extension of optoelectronic applications to visible and ultraviolet(UV) wavelengths.

立足于金融供给的地理结构视角,本文利用2005—2012年工业企业数据库、中国商业银行分支机构数据与工业企业污染排放数据库的匹配数据,根据企业地理位置和中国商业银行分支机构的地理位置信息,计算得出银企间的距离数据,分析了银企距离对企业污染排放的影响,并进一步运用绿色信贷政策与绿色银行网点数量,分析了绿色金融政策对银企距离的减排作用的调节效应。研究发现:银企距离的缩短会显著降低企业排污水平,且该减排效应通过倒逼企业研发绩效增加和缓解企业融资约束来实现。绿色金融的发展与绿色银行网点数量的增加,会增强银企距离缩短对企业的减排效应。本文进一步丰富了银企距离的相关理论,同时对于金融发展助力“碳中和”实现提供了新的研究视角。

金融科技如何更好地提升传统金融服务实体企业的效率,降低系统性金融风险,是各方关注的焦点。文章使用2010—2021年中国商业银行实用新型与发明专利申请数据,并与上市公司财务与银行贷款明细数据进行匹配,构造出银行金融科技指标,分析其对企业债务违约风险的影响。研究结论表明:首先,银行金融科技发展水平的提升能够显著降低企业债务违约风险;其次,从影响机制上看,在资金需求侧,银行金融科技发展能够提升企业财务质量;在资金供给侧,会通过信息共享机制增强银行信息甄别能力。异质性分析显示:对于规模较小的银行以及非国有六大银行,金融科技对企业债务违约的降低效应更为显著;对于成长型企业,上述效应相对较弱。进一步分析表明:银行金融科技发展能够显著改善企业营业利润率,降低经营风险,提升企业投融资效率,有效解决银行无序竞争产生的负面影响。文章研究结论拓展了信息不对称、金融错配以及企业债务违约相关理论的经验证据,对促进新业态下金融更好地服务实体企业、降低信贷违约风险具有重要的现实意义。
