Sugarcane (Saccharum spp.) is an important sugar crop. Biotic and abiotic stresses such as diseases, cold, and drought are major factors limiting sugarcane production. β-1,3-glucanase (EC 3.2.1.39), a member of the pathogenesis-related protein family, plays an essential role not only in the plant defenses against pathogens but also in plant growth, development, and abiotic stress responses. To systematically investigate the sugarcane β-1,3-glucanase gene family, 132 glycoside hydrolase (GH) 17 family members were identified in the genomes of the sugarcane wild species Saccharum spontaneum 'Np-X', the tropical species S. officinarum 'LA-Purple', and the Saccharum spp. hybrid cultivar 'R570'. The results of the phylogenetic analysis categorized them into four subfamilies, of which subfamily Ⅳ had the largest proportion of members (102). The members of the sugarcane GH17 gene family contained five conserved motifs and 0-16 introns. The majority of the GH17 genes exhibited a genome-wide replication pattern, with 89.50% originating from S. spontaneum 'Np-X' and S. officinarum 'LA-Purple', while 58.10% of them in the Saccharum spp. hybrid cultivar 'R570' belonged to the discrete replication type. Four major classes of cis-acting elements were identified in the promoters, including the elements related to plant growth, development, and tissue-specific expression (14.21%), light-responsive elements (38.24%), biotic or abiotic stress-responsive elements (9.18%), and hormone-responsive elements (38.37%), which suggested that this gene family was involved in plant growth, development, hormone responses, and stress responses. Transcriptome and quantitative real-time PCR (RT-qPCR) analyses showed that the sugarcane GH17 genes exhibited tissue-specific expression and were differentially expressed under low temperature, drought, and hormone treatments, as well as during the interactions between different sugarcane genotypes and Sporisorium scitamineum, suggesting their potential roles in plant defenses. In addition, some SsGlu genes (SsGlu5, SsGlu20, SsGlu21, SsGlu25, SsGlu28, and SsGlu39) were expected to serve as candidate stress-related genes. This study lays a foundation for further revealing the molecular mechanisms of the stress resistance of sugarcane via β-1,3-glucanase genes.

Craniosynostosis is a prevalent congenital craniofacial anomaly characterized by premature fusion of cranial sutures. It is of great social significance for the study and prevention of the genetic mechanism of craniosynostosis. Mutant genes such as FGFR1, FGFR2, FGFR3, TWIST1, MSX2, RAB, ERF related to craniosynostosis has been identified in humans, leading to the generation of a large number of recombinant animal models with similar functional acquisition or loss mutations to simulate various manifestations of craniosynostosis. The similarity of craniofacial development and molecular pathways between mice and humans makes them a good animal model for studying craniosynostosis. This article reviews the research progress of mouse models related to syndromic, non-syndromic craniosynostosis and craniosynostosis with non-human gene mutations, in order to provide a more comprehensive and systematic understanding of the genetic pathogenesis and treatment of this disease.

Gynecological cancers present significant treatment challenges due to drug resistance and adverse side effects. This review explores advancements in lysosomal escape mechanisms, essential for enhancing nano-therapeutic efficacy. Strategies such as pH-sensitive linkers and membrane fusion are examined, showcasing their potential to improve therapeutic outcomes in ovarian, cervical, and uterine cancers. We delve into novel materials and strategies developed to bypass the lysosomal barrier, including pH-sensitive linkers, fusogenic lipids, and nanoparticles (NPs) engineered for endosomal disruption. Mechanisms such as the proton sponge effect, where NPs induce osmotic swelling and rupture of the lysosomal membrane, and membrane fusion, which facilitates the release of therapeutic agents directly into the cytoplasm, are explored in detail. These innovations not only promise to improve therapeutic outcomes but also minimize side effects, marking a significant step forward in the treatment of ovarian, cervical, and uterine cancers. By providing a comprehensive analysis of current advancements and their implications for clinical applications, this review sheds light on the potential of lysosomal escape strategies to revolutionize gynecological cancer treatment, setting the stage for future research and development in this vital area.
