| 1 | ESCRT-Ⅲ component OsSNF7.2 modulates leaf rolling by trafficking and endosomal degradation of auxin biosynthetic enzyme OsYUC8 in rice显示文摘The endosomal sorting complex required for transport(ESCRT)is highly conserved in eukaryotic cells and plays an essential role in the biogenesis of multivesicular bodies and cargo degradation to the plant vacuole or lysosomes.Although ESCRT components affect a variety of plant growth and development processes,their impact on leaf development is rarely reported.Here,we found that OsSNF7.2,an ESCRT-Ⅲ component,controls leaf rolling in rice(Oryza sativa).The Ossnf7.2 mutant rolled leaf 17(rl17)has adaxially rolled leaves due to the decreased number and size of the bulliform cells.OsSNF7.2is expressed ubiquitously in all tissues,and its protein is localized in the endosomal compartments.OsSNF7.2 homologs,including OsSNF7,OsSNF7.3,and OsSNF7.4,can physically interact with OsSNF7.2,but their single mutation did not result in leaf rolling.Other ESCRT complex subunits,namely OsVPS20,OsVPS24,and OsBRO1,also interact with OsSNF7.2.Further assays revealed that OsSNF7.2 interacts with OsYUC8 and aids its vacuolar degradation.Both Osyuc8and rl17 Osyuc8 showed rolled leaves,indicating that OsYUC8 and OsSNF7.2 function in the same pathway,conferring leaf development.This study reveals a new biological function for the ESCRT-Ⅲcomponents,and provides new insights into the molecular mechanisms underlying leaf rolling. | Liang Zhou Saihua Chen Maohong Cai Song Cui Yulong Ren Xinyue Zhang Tianzhen Liu Chunlei Zhou Xin Jin Limin Zhang Minxi Wu Shuyi Zhang Zhijun Cheng Xin Zhang Cailin Lei Qibing Lin Xiuping Guo Jie Wang Zhichao Zhao Ling Jiang Shanshan Zhu Jianmin Wan | 2023 | Journal of Integrative Plant Biology2023，65，6： | 1 |

| 3 | Enhancing the HSV-1-mediated antitumor immune response by suppressing Bach1显示文摘Background In 2015,herpes simplex virus 1(HSV-1)-derived talimogene laherparepvec(T-VEC)was the first oncolytic virus approved by the US Food and Drug Administration as a therapeutic agent for cancer treatment.However,its antitumor application is limited to local treatment of melanoma,and there is a lack of understanding of the mechanisms underlying the regulation of HSV-1 replication in cancer cells and the associated antitumor immunity.We hypothesized that increasing the replication capacity of HSV-1 in tumor cells would enhance the antitumor effect of this virus.Methods We systematically identified IFN-stimulated genes induced by HSV-1 by performing functional screens and clarified the mechanism by which BACH1 acts against HSV-1.Then,we tested the effect of BACH1 deficiency on immunogenic cell death induced by HSV-1.Furthermore,we investigated the antitumor effect of BACH1 deficiency on HSV-1 in MCA205 and B16 murine tumor models.Results We identified eight IFN-stimulated genes(ISGs)controlling HSV-1 replication,among which BTB and CNC homology 1(BACH1)suppressed HSV-1 replication by inhibiting the transcription of ICP4,ICP27,and UL39.Loss of Bach1 function not only increased HSV-1 proliferation but also promoted HSV-1-induced cell apoptosis,HMGB1 secretion,and calreticulin exposure in tumor cells.More importantly,hemin,an FDA-approved drug known to downregulate BACH1,significantly enhanced HSV-1-mediated antitumor activity with increased T lymphocyte infiltration at the tumor site.Conclusions Our studies uncovered a novel antiviral activity of BACH1 and provided a new strategy for improving the clinical efficiency of the oncolytic virus HSV-1. | Chaohu Pan Qiaomei Cai Xiaorong Li Lili Li Liping Yang Yu Chen Junxiao Liu Wancheng Liu Meiling Gao Tianqi Sui Xiaoyang Wang Huiming Fan Jiayin Ruan Yueyue Shi Saihua Chen Lucy S.Cheng Jiayong Liu Heng Yang Genhong Cheng | 2022 | Cellular & Molecular Immunology2022，19，4： | 0 |

| 5 | Effects and safety of Ding Kun Dan on IVF/ICSI-ET outcomes in patients with predicted poor ovarian response:A multicenter randomized clinical trial显示文摘Objective:To evaluate whether Ding Kun Dan(DKD)can improve the vitro fertilization/intracytoplasmic sperm injection and embryo transfer(IVF/ICSI-ET)outcomes in patients with predicted poor ovarian response(POR)safely and effectively.Methods:Prospective,multicenter,randomized controlled trial;A total of 278 POR patients were randomized in DKD group or immediate treatment group.Both groups received IVF or ICSI as a standard treatment while in the DKD group,DKD was administrated for 3 months before the IVF/ICSI cycle.The primary outcome was the ongoing pregnancy rate.The secondary outcomes include clinical pregnancy rate,biochemical pregnancy rate,total gonadotropin(Gn)dosage and duration,estradiol(E2)and progesterone(P)levels on human chorionic gonadotropin(hCG)trigger day,cycle cancellation rate,number of oocytes retrieved,high-quality embryo rate and any adverse events.Results:Compared to the immediate IVF treatment group,oral administration of DKD for 3 months before IVF led to a significant increase in ongoing pregnancy rate(30.0%v.s.17.6%,P<0.05),biochemical pregnancy rate(39.2%vs.25.2%,P<0.05),clinical pregnancy rate(36.7%vs.22.7%,P<0.05)and high-quality embryo rate(40.8%vs.32.4%,P<0.05),and a significant decrease in Gn duration(P<0.05).However,no significant differences were found in total dosage of Gn,number of retrieved oocytes,cycle cancellation rate,E2 level and P level on hCG trigger days(P>0.05).No serious adverse events occurred during the intervention period in either group.Conclusion:DKD is a safe and effective intervention to improve the IVF/ICSI-ET outcomes in patients with POR. | Saihua Ma Guimin Hao Jiayi Song Zhimei Zhao Baojuan Wang Xueru Song Fengqin Xu Yan Liu Tian Xia | 2021 | TMR Modern Herbal Medicine2021，4，3： | 0 |
| 6 | Responses of Carbonic Anhydrase to Cadmium in the Zinc/Cadmium Hyperaccumulator Picris divaricata Vant.显示文摘A number of higher plants are able to hyperaccumulate cadmium(Cd). However, it is unknown whether cadmium(Cd) plays a biological functional role in the carbonic anhydrase(CA) of hyperaccumulators. A hydroponic experiment was conducted to explore the potentially physiological function of Cd in CA and the accumulation and tolerance of Cd in the Zn/Cd hyperaccumulator Picris divaricata Vant. P. divaricata was exposed to nutrient solutions with six Cd concentrations(0, 5, 10, 25, 50 and 75 μmol L^(-1)). After 12 d, plants were harvested for the analysis of plant biomass, Cd concentration and CA activity. The Cd concentrations in plant increased with the increasing Cd in nutrient solution, reaching 640 and 3 100 mg kg^(-1) in shoot and root, respectively, at the 75 μmol L^(-1) Cd treatment. Meanwhile, plant growth was enhanced by the Cd treatments at 5–25 μmol L^(-1), but it was significantly inhibited when the plants were exposed to solutions with higher Cd concerntrations(50 and 75 μmol L^(-1)). Exposure to Cd significantly increased the CA activity in P. divaricata, which reached a maximum value of 21.27 U mg^(-1) proteins at the 25 μmol L^(-1)Cd treatment, and the CA activity and shoot Cd concentration were positively correlated at solutions Cd of ≤ 25 μmol L^(-1). Moreover, two protein bands appeared on the denatured gel electrophoresis of purified CA, indicating that P. divaricata may have CA isomers with their respective molecular weights at around 60 and 55 k Da, at least one of which is Cd-bound. In addition, trace amounts of Cd in purified CA significantly increased with the supplied Cd concentration in nutrient solution(5–25 μmol L^(-1)). The results suggested that Cd may play a biological role by enhancing the activities and forming the active Cd-specific CA in the hyperaccumulator P. divaricata. | LIU Saihua TANG Yetao QIU Rongliang YING Rongrong GE Ruiguang JI Xionghui | 2016 | Pedosphere2016，26，5： | 0 |
