| 2 | Tumor-microenvironment activated duplex genome-editing nanoprodrug for sensitized near-infrared titania phototherapy显示文摘Near-infrared(NIR)-light-triggered nanomedicine, including photodynamic therapy(PDT)and photothermal therapy(PTT), is growing an attractive approach for cancer therapy due to its high spatiotemporal controllability and minimal invasion, but the tumor eradication is limited by the intrinsic anti-stress response of tumor cells. Herein, we fabricate a tumor-microenvironment responsive CRISPR nanoplatform based on oxygen-deficient titania(TiO_(2-x)) for mild NIR-phototherapy. In tumor microenvironment, the overexpressed hyaluronidase(HAase) and glutathione(GSH) can readily destroy hyaluronic acid(HA) and disulfide bond and releases the Cas9/sgRNA from TiO_(2-x) to target the stress alleviating regulators, i.e., nuclear factor E2-related factor 2(NRF2) and heat shock protein 90a(HSP90a), thereby reducing the stress tolerance of tumor cells. Under subsequent NIR light illumination, the TiO_(2-x) demonstrates a higher anticancer effect both in vitro and in vivo. This strategy not only provides a promising modality to kills cancer cells in a minimal side-effects manner by interrupting anti-stress pathways but also proposes a general approach to achieve controllable gene editing in tumor region without unwanted genetic mutation in normal environments. | Zekun Li Yongchun Pan Shiyu Du Yayao Li Chao Chen Hongxiu Song Yueyao Wu Xiaowei Luan Qin Xu Xiaoxiang Guan Yujun Song Xin Han | 2022 | Acta Pharmaceutica Sinica B2022，12，11： | 0 |
| 3 | Author correction to “Tumor-microenvironment activated duplex genome-editing nanoprodrug for sensitized near-infrared titania phototherapy” [Acta Pharm Sin B (2022) 4224-4234]显示文摘The authors regret that there is an error in the article Fig.5E due to the mistake of copying and pasting in the process of assembling figures and negligence in the proofreading.Although it does not affect the conclusion,it is an obvious error.The authors have now modified as below.The authors apologize for any inconvenience caused to the journal and readers. | Zekun Li Yongchun Pan Shiyu Du Yayao Li Chao Chen Hongxiu Song Yueyao Wu Xiaowei Luan Qin Xu Xiaoxiang Guan Yujun Song Xin Han | 2024 | Acta Pharmaceutica Sinica B2024，14，2： | 0 |
| 4 | Activation of the 5-hydroxytryptamine 4 receptor ameliorates tight junction barrier dysfunction in the colon of type 1 diabetic mice显示文摘Hyperglycemia drives dysfunction of the intestinal barrier.5-Hydroxytryptaine 4 receptor(5-HT4R)agonists have been considered therapeutics for constipation in clnic.However,the roles of 5-HT4R activation in mucosa should be fully realized.Here,we investigate the effects of 5-HT4R activation on diabetes-induced disruption of the tight junction(TJ)barrier in the colon.Not surprisingly,the TJ barrier in diabetic mice with or without 5-HT4R is tremendously destroyed,as indicated by increased serum fluorescein isothiocyanate(FITC)-dextran and decreased transepithelial electrical resistance(TER).Simultaneously,decreased expressions of TJ proteins are shown in both wild-type(WT)and 5-HT4R knockout(KO)mice with diabetes.Notably,chronic treatment with intraperitoneal injection of a 5-HT4R agonist in WT mice with diabetes repairs the TJ barrier and promotes TJ protein expressions,including occludin,claudin-1 and ZO-1,in the colon,whereas a 5-HT4R agonist does not improve TJ barrier function or TJ protein expressions in 5-HT4R KO mice with diabetes.Furthermore,stimulation of 5-HT4R inhibits diabetesinduced upregulation of myosin light chain kinase(MLCK),Rho-associated coiled coil protein kinase 1(ROCK1),and phosphorylated myosin light chain(p-MLC),which are key molecules that regulate TJ integrity,in the colonic mucosa of WT mice.However,such action induced by a 5-HT4R agonist is not observed in 5-HT4R KO mice with diabetes.These findings indicate that 5-HT4R activation may restore TJ integrity by inhibiting the expressions of MLCK,ROCK1 and p-MLC,improving epithelial barrier function in diabetes. | Shasha Hu Yueting Kou Xiaochen Liu Weifang Rong Hongxiu Han Guohua Zhang | 2023 | Acta Biochimica et Biophysica Sinica2023，55，12： | 0 |
