根据文献报道并通过circBase数据库查找,发现小鼠生长激素受体基因(growth hormone receptor,GHR)存在8个环状转录本。为确定GHR基因环状转录本(circGHR)的真实存在,探究其表达规律,本研究以昆明小鼠(Mus musculus)为研究对象,通过PCR扩增和测序检测circGHR的真实存在,并筛选出一个circGHR作为目标分子,通过RNase R处理和反转录证实了circGHR的环形结构,利用qRT-PCR分析circGHR和GHR mRNA的时空表达规律。结果表明:小鼠circGHR全长为820 nt,由GHR基因外显子2~8环化形成。RNase R耐受性分析表明,小鼠circGHR具备环形分子的一般特征,不易被RNase R降解。与oligo-d(T)18引物相比,随机引物对circGHR具有较高的反转录效率,进一步说明circGHR是一个不含poly(A)的环状结构分子。组织表达谱结果表明,circGHR在1周龄和7周龄小鼠肝脏和肾脏高表达,在胸肌和腿肌中低表达;circGHR在肝脏和胸肌组织的时序表达谱结果表明circGHR表达无显著差异;circGHR在腿肌组织的时序表达谱结果表明,circGHR在小鼠5周龄之前为低表达,在7周龄以后表现为高表达。本研究结果证实了小鼠GHR基因存在一个环状转录本circGHR,并初步揭示了circGHR的表达规律,为后期深入开展小鼠circGHR的生物学功能及其在小鼠生长发育过程中的作用机制奠定基础。

矮小鸡(Gallus domesticus)由于其体型小,节约养殖空间等优点常被用于鸡配套系生产。本研究为明确矮小体型芦花鸡的生长激素受体(growth hormone receptor, GHR)基因突变类型,探究正常体型芦花鸡和矮小体型芦花鸡间的生长发育差异,针对矮小体型芦花鸡GHR基因常见的4种突变位点设计引物,以矮小体型芦花鸡的基因组DNA为模板进行PCR扩增,分析其遗传变异类型。同时比较分析了正常体型芦花鸡与矮小体型芦花鸡体重和胫长的发育特点,使用Logistic、Gompertz和Von Bertalanffy 3种数学模型拟合分析了其最适模型和拟合参数。结果显示,与正常体型芦花鸡相比,矮小体型芦花鸡GHR基因缺失了1 781 bp的碱基序列。正常体型芦花鸡与矮小体型芦花鸡在1～13周龄期间发育差异明显,尤其在体重和胫长2个性状对比明显。Logistic是正常体型芦花鸡与矮小体型芦花鸡体重的最优拟合模型(R2>0.990)。对于胫长而言,在雄性芦花鸡中,正常体型芦花鸡的最佳拟合模型为Logistic,矮小体型芦花鸡的最适拟合模型为Von Bertalanffy。在雌性芦花鸡中,正常体型芦花鸡和矮小体型芦花鸡的最佳拟合模型均为Von Bertalanffy。本研究为芦花鸡精细饲养管理和矮小芦花鸡的分子标记辅助育种提供了参考依据。

The use of privacy-enhanced facial recognition has increased in response to growing concerns about data securityand privacy in the digital age. This trend is spurred by rising demand for face recognition technology in a varietyof industries, including access control, law enforcement, surveillance, and internet communication. However,the growing usage of face recognition technology has created serious concerns about data monitoring and userprivacy preferences, especially in context-aware systems. In response to these problems, this study provides a novelframework that integrates sophisticated approaches such as Generative Adversarial Networks (GANs), Blockchain,and distributed computing to solve privacy concerns while maintaining exact face recognition. The framework’spainstaking design and execution strive to strike a compromise between precise face recognition and protectingpersonal data integrity in an increasingly interconnected environment. Using cutting-edge tools like Dlib for faceanalysis,Ray Cluster for distributed computing, and Blockchain for decentralized identity verification, the proposedsystem provides scalable and secure facial analysis while protecting user privacy. The study’s contributions includethe creation of a sustainable and scalable solution for privacy-aware face recognition, the implementation of flexibleprivacy computing approaches based on Blockchain networks, and the demonstration of higher performanceover previous methods. Specifically, the proposed StyleGAN model has an outstanding accuracy rate of 93.84%while processing high-resolution images from the CelebA-HQ dataset, beating other evaluated models such asProgressive GAN 90.27%, CycleGAN 89.80%, and MGAN 80.80%. With improvements in accuracy, speed, andprivacy protection, the framework has great promise for practical use in a variety of fields that need face recognitiontechnology. This study paves the way for future research in privacy-enhanced face recognition systems, emphasizingt
