Chemotherapy is regarded as a widely used and effective treatment strategy for lung cancer, although most conventional chemotherapeutics cause severe toxic side-effects due to their indiscriminate attacks on both cancerous and normal cells. Although nucleic acid nanomaterials are emerging as a promising drug delivery strategy, their clinical applications are limited by rapid degradation by nucleases and difficulties in targeting cancer cells. In this study, we have developed a Rhein-loaded aptamer-based DNA nanotube(DNT-S6@Rhein) for the targeted and efficient therapy of non-small cell lung cancer. Through the palindrome segments, two specified oligonucleotides were hybridized and folded into the well-defined nanotubes(DNT-S6), with the S6 aptamer distributed outside. The obtained nanotubes exhibited excellent serum stability and targeting ability towards A549 cells due to the firm structure and decoration of the S6 aptamer. Rhein, as an antitumor drug and DNA intercalator, can be effectively inserted into the DNT-S6. The drug-loaded nanotubes rapidly disassembled in intracellular environment and then the released Rhein was found to activate cellular apoptotic process and significantly suppress proliferation, migration and invasion of A549 cells. Moreover, DNT-S6@Rhein could efficiently accumulate in tumor regions, offering compelling therapeutic efficacy and biocompatibility under both in vitro and in vivo settings. These findings of this study provide a promising strategy for mitigating the inevitable systemic side-effects of chemotherapy and expand the potential application of DNA nanostructure on targeted drug delivery.

Zinc finger transcription factors BnaSTOP2s regulate sulfur metabolism and confer Sclerotinia sclerotiorum resistance in Brassica napus

引用

Journal of Integrative Plant biology 2025年第1期67卷 101-116页

作者： Lihong Dai Zhaoqi Xie Tianxu Ai Yushun Jiao Xiaoyi Lian Angchen Long Jinyun Zhang Guangsheng Yang Dengfeng Hong National Key laboratory of Crop Genetic Improvement College of Plant Science and Technology Huazhong Agricultural University Lushan Botanical Garden Chinese Academy of Sciences Hubei Hongshan laboratory Yazhouwan National laboratory

Rapeseed(Brassica napus L.) exhibits high-sulfur requirements to achieve optimal growth, development, and pathogen resistance. Despite the importance of sulfur, the mechanisms regulating its metabolism and disease resistance are not fully understood. In this study, we found that the zinc finger transcription factors BnaSTOP2s play a pivotal role in sulfur metabolism and Sclerotinia sclerotiorum resistance. Our findings indicate that BnaSTOP2s are involved in sulfur metabolism, as evidenced by extensive protein interaction screening. BnaSTOP2s knockout reduced the content of essential sulfurcontaining metabolites, including glucosinolate and glutathione, which is consistent with the significantly lowered transcriptional levels of BnaMYB28s and BnaGTR2s, key factors involved in glucosinolate synthesis and transportation, respectively. Comprehensive RNA-seq analysis revealed the substantial effect of BnaSTOP2s on sulfur metabolism from roots to siliques, which serve as pivotal sources and sinks for sulfur metabolism, respectively. Furthermore, we found that leaf lesion size significantly decreased and increased in the BnaSTOP2-OE and Bnastop2 mutants, respectively, compared with the wild-type during S. sclerotiorum infection, suggesting a vital role of BnaSTOP2s in plant defense *** conclusion, BnaSTOP2s act as global regulators of sulfur metabolism and confer resistance to S. sclerotiorum infection in B. napus. Thus, they have potential implications for improving crop resilience.
