The Rbfox proteins regulate alternative pre-mRNA splicing by binding to the RNA element GCAUG. In the nucleus, most of Rbfox is bound to the large assembly of splicing regulators (LASR), a complex of RNA-binding proteins that recognize additional RNA motifs. However, it remains unclear how the different subunits of the Rbfox/LASR complex act together to bind RNA and regulate splicing.

Identification and functional analyses of the CmdsRNase5 and CmdsRNase6 genes in rice leaffolder Cnaphalocrocis medinalis.

RNA interference (RNAi) is a promising method for pest control; however, some studies have showed that the degradation of double-stranded RNA (dsRNA) by dsRNA-degrading nucleases (dsRNases) is one of the factors that may reduce RNAi efficiency in lepidopteran insects. In this study, we cloned two dsRNase genes named CmdsRNase5 and CmdsRNase6 from rice leaffolder Cnaphalocrocis medinalis, a notorious insect pest of rice. Open reading frames (ORFs) of CmdsRNase5 and CmdsRNase6 are 1317 and 1185 bp in length, encoding 438 and 394 amino acids, respectively.

Electronic address:

Aptamers and aptamer-drug conjugates (ApDCs) have shown some success as targeted therapies in cancer theranostics. However, their stability in complex media and their capacity to evade lysosomal breakdown still need improvement. To address these challenges, we herein developed a one-step self-assembly strategy to improve the stability of aptamers or ApDCs, while simultaneously enhancing their delivery performance and therapeutic efficiency through a lysosome-independent pathway.

The association between microRNAs and various diseases, especially cancer, has been established in recent years, indicating that miRNAs can potentially serve as biomarkers for these diseases. Determining miRNA concentrations in biological samples is crucial for disease diagnosis. Nevertheless, the stem-loop reverse transcription quantitative PCR method, the gold standard for detecting miRNA, has great challenges in terms of high costs and enzyme limitations when applied to clinical biological samples.

Advances and applications of genome-edited animal models for severe combined immunodeficiency.

Stomatological Hospital, School of Stomatology, Southern Medical University, Guangzhou, Guangdong 510280, China. E-mail:

Severe combined immunodeficiency disease (SCID), characterized by profound immune system dysfunction, can lead to life-threatening infections and death. Animal models play a pivotal role in elucidating biological processes and advancing therapeutic strategies. Recent advances in gene-editing technologies, including zinc-finger nucleases (ZFNs), transcription activator-like effector nucleases (TALENs), CRISPR/Cas9, and base editing, have significantly enhanced the generation of SCID models.
