| 4 | Novel cyclophosphamide of natural products osalmide and pterostilbene induces cytotoxicity and cell cycle arrest in diffuse large B-cell lymphoma cells显示文摘Diffuse large B-cell lymphoma(DLBCL)is the most common category and disease entity of non-Hodgkin lymphoma.Osalmide and pterostilbene are natural products with anticancer activities via different mechanism.In this study,using a new synthetic strategy for the two natural products,we obtained the compound DCZ0801,which was previously found to have anti-multiple myeloma activity.We performed both in vitro and in vivo assays to investigate its bioactivity and explore its underlying mechanism against DLBCL cells.The results showed that DCZ0801 treatment gave rise to a dose-and time-dependent inhibition of cell viability as determined by CCK-8 assay and flow cytometry assay.Western blot analysis results showed that the expression of caspase-3,caspase-8,caspase-9 and Bax was increased,while BCL-2 and BCL-XL levels were decreased,which suggested that DCZ0801 inhibited cell proliferation and promoted intrinsic apoptosis.In addition,DCZ0801 induced G0/G1 phase arrest by downregulating the protein expression levels of CDK4,CDK6 and cyclin D1.Furthermore,DCZ0801 exerted an anti-tumor effect by down-regulating the expressions of p-PI3K and p-AKT.There also existed a trend that the expression of p-JNK and p-P38 was restrained.Intraperitoneal injection of DCZ0801 suppressed tum or development in xenograft mouse models.The preliminary metabolic study showed that DCZ0801 displayed a rapid metabolism within 30 min.These results demonstrated that DCZ0801 may be a new potential anti-DLBCL agent in DLBCL therapy. | Mengyu Xi Wan He Bo Li Jinfeng Zhou Zhijian Xu Huiqun Wu Yong Zhang Dongliang Song Liangning Hu Ye Lu Wenxuan Bu Yuanyuan Kong Gege Chen Shuaikang Chang Jumei Shi Weiliang Zhu | 2020 | Acta Biochimica et Biophysica Sinica2020，52，4： | 0 |
| 5 | Acute salinity and temperature challenges during early development of zebrafish:Differential gene expression of PTHs,PTHrPs and their receptors显示文摘Parathyroid hormone(pth),parathyroid hormone-related peptide(pthrp)and their receptors are involved in the regulation of calcium homeostasis in all vertebrates.To further understand the role of these genes in teleosts during development,we investigated the expression pattern of pth1,pth2,pthrp1,pthrp2,and their receptors pth1r,pth2r,pth3r,and their response to acute salinity and temperature challenge during early development of zebrafish,Danio rerio.The results revealed that pth1,pth2,pthrp1,pthrp2,pth1r,pth2r,pth3r were differentially expressed during early development,and pth1,pthrp1,pth1r,pth2r mRNA were detected from 0 hpf.pth2 and pth3r mRNA were detected after fertilization.Exposure of zebrafish embryos and larvae to acute osmotic(30)stress for 15 min failed to modify the expression levels of pthrp2 mRNA from levels in control fish.However,salinity challenge significantly(P<0.01)modified pth1,pth2,pth3r at 3 dpf,pthrp1(P<0.01)and pth1r(P<0.05)were both significantly modified at 5 dpf,and pth2r was significantly(P<0.01)modified at 4 dpf and 5 dpf.Exposure of embryos and larvae to a cold(18℃)stress generally up-regulated mRNA levels of pth1,pth2,pthrp1,pthrp2 and pth3r from 2 dpf to 5 dpf,while a hot(38℃)stress generally down-regulated mRNA levels of these genes.After acute temperature challenge,expression levels of pth receptors were greatly influenced except pth2r.The results indicate that the contribution of pth1,pth2,pthrp1,pthrp2,pth1r,pth2r and pth3r genes to the stress response in zebrafish may be stressor-specific during early development.Overall,the results from this study provide a basis for further research into the developmental and stressor-specific role of pth1,pth2,pthrp1,pthrp2,pth1r,pth2r and pth3r in zebrafish. | Yingying Jin Zhaohui Lan Gege Zhu Weiqun Lu | 2017 | Aquaculture and Fisheries2017，2，2： | 0 |
| 6 | antitumor activity in bortezomib-resistant multiple myeloma cells through inhibition of JAK2/STAT3 pathway显示文摘Multiple myeloma(MM),the second most common haematological malignancy,is currently incurable because patients often develop multiple drug resistance and experience subsequent relapse of the disease.This study aims to identify a potential therapeutic agent that can counter bortezomib(BTZ)resistance in MM.DCZ0358,a novel alkaloid compound,is found to exert potent cytotoxic effects against BTZ-resistant MM cells in vivo and in vitro.The antimyeloma activity of DCZ0358 is associated with inhibition of cell proliferation,promotion of cell apoptosis via caspase-mediated apoptotic pathways,and induction of G0/G1 phase arrest via downregulation of cyclin D1,CDK4,and CDK6.Further investigation of the molecular mechanism shows that DCZ0358 suppresses the JAK2/STAT3 signaling pathway.In conclusion,DCZ0358 can successfully counter BTZ resistance in MM cells.This study provides evidence that warrants future preclinical assessments of DCZ0358 as a therapeutic agent against BTZ resistance in MM. | Bibo Zhang Bo Li Yongsheng Xie Shuaikang Chang Zhijian Xu Huifang Hu Gege Chen Ting Zhang Jun He Xiaosong Wu Huabin Zhu Weiming Lai Dongliang Song Ying Lu Xinyan Jia Weiliang Zhu Jumei Shi | 2023 | Acta Biochimica et Biophysica Sinica2023，55，2： | 0 |
| 7 | A novel silicone derivative of natural osalmid(DCZ0858)induces apoptosis and cell cycle arrest in diffuse large B-cell lymphoma via the JAK2/STAT3 pathway显示文摘Diffuse large B-cell lymphoma(DLBCL)is a highly heterogeneous malignant tumor characterized by diffuse growth.DCZ0858 is a novel small molecule with excellent antitumor effects in DLBCL.This study explored in depth the inhibitory effect of DCZ0858 on DLBCL cell lines.Cell Counting Kit-8(CCK-8)and plate colony formation assays were used to evaluate cell proliferation levels.Flow cytometry was employed to analyze apoptosis and the cell cycle,and western blotting was used to quantify the expression of cell cycle regulators.The results indicated that DCZ0858 inhibited cell growth in a concentration-dependent and time-dependent manner while inducing no significant toxicity in normal cells.Moreover,DCZ0858 initiated cell apoptosis via both internal and external apoptotic pathways.DCZ0858 also induced cell cycle arrest in the G0/G1 phase,thereby controlling cell proliferation.Further investigation of the molecular mechanism showed that the JAK2/STAT3 pathway was involved in the DCZ0858-mediated antitumor effects and that JAK2 was the key target for DCZ0858 treatment.Knockdown of JAK2 partly weakened the DCZ0858-mediated antitumor effect in DLBCL cells,while JAK2 overexpression strengthened the effect of DCZ0858 in DLBCL cells.Moreover,a similar antitumor effect was observed for DCZ0858 and the JAK2 inhibitor ruxolitinib,and combining the two could significantly enhance cancer-suppressive signaling.Tumor xenograft models showed that DCZ0858 inhibited tumor growth in vivo and had low toxicity in important organs,findings that were consistent with the in vitro data.In summary,DCZ0858 is a promising drug for the treatment of DLBCL. | Kang Lu Bo Li Hui Zhang Zhijian Xu Dongliang Song Lu Gao Haiguo Sun Liping Li Yingcong Wang Qilin Feng Gege Chen Liangning Hu Rong Wei Yongsheng Xie Dandan Yu Xiaosong Wu Weiliang Zhu Jumei Shi | 2020 | Signal Transduction and Targeted Therapy2020，5，1： | 0 |
| 8 | Dihydrocelastrol induces antitumor activity and enhances the sensitivity of bortezomib in resistant multiple myeloma by inhibiting STAT3-dependent PSMB5 regulation显示文摘Multiple myeloma(MM)is characterized by excessive aggregation of B-cell-derived malignant plasma cells in the hematopoietic system of bone marrow.Previously,we synthesized an innovative molecule named dihydrocelastrol(DHCE)from celastrol,a triterpene purified from medicinal plant Tripterygium wilfordii.Herein,we explore the therapeutic properties and latent signal transduction mechanism of DHCE action in bortezomib(BTZ)-resistant(BTZ-R)MM cells.In this study,we first report that DHCE shows antitumor activities in vitro and in vivo and exerts stronger inhibitory effects than celastrol on BTZ-R cells.We find that DHCE inhibits BTZ-R cell viability by promoting apoptosis via extrinsic and intrinsic pathways and suppresses BTZ-R MM cell proliferation by inducing G0/G1 phase cell cycle arrest.In addition,inactivation of JAK2/STAT3 and PI3K/Akt pathways are involved in the DHCE-mediated antitumor effect.Simultaneously,DHCE acts synergistically with BTZ on BTZ-R cells.PSMB5,a molecular target of BTZ,is overexpressed in BTZ-R MM cells compared with BTZ-S MM cells and is demonstrated to be a target of STAT3.Moreover,DHCE downregulates PSMB5 overexpression in BTZ-R MM cells,which illustrates that DHCE overcomes BTZ resistance through increasing the sensitivity of BTZ in resistant MM via inhibiting STAT3-dependent PSMB5 regulation.Overall,our findings imply that DHCE may become a potential therapeutic option that warrants clinical evaluation for BTZ-R MM. | Shuhan Jin Bo Li Bibo Zhang Xuejie Gao Xinyan Jia Li Xu Shuaikang Chang Ke Hu Guanli Wang Zhijian Xu Ting Zhang Dongliang Song Guang Yang Xiaosong Wu Huabin Zhu Cheng Huang Yumeng Lu Jumei Shi Weiliang Zhu Gege Chen | 2023 | Acta Biochimica et Biophysica Sinica2023，55，12： | 0 |
| 9 | Attitudes of hospitalized patients toward wearing patient clothing in Tianjin,China:A cross-sectional survey显示文摘Objective:To assess the attitudes of hospitalized patients toward wearing patient clothing and identify the factors those influence their negative attitudes.Methods:A cross-sectional design was employed and a questionnaire survey was conducted.The data were collected from 251 hospitalized patients between July 2015 and August 2015.Results:Around 57.8%of the participants reported that they were unwilling to wear patient clothing.Among them,60.7%knew little to nothing about the function of patient clothing.Some of these patients were unwilling to wear patient clothing because these uniforms had poor comfort(26.2%),fit(34.5%),hygiene(66.2%),and appearance(31.1%),and wearing them was psychologically uncomfortable(43.5%).Conclusions:More than half of the hospitalized patients dislike wearing patient clothing because they were unaware of its functions and were skeptical about its hygiene,comfortability,fit,and appearance.Therefore,these patients must be provided with comfortable,well fitting,hygienic,and aesthetically pleasing clothing. | Lu Liu Haofeng Zhao Gege Lu Yulu Ling Lingjie Jiang Huilan Cai Weijie Gao | 2016 | International Journal of Nursing Sciences2016，3，4： | 0 |
