| 1 | Substance P-modified human serum albumin nanoparticles loaded with paclitaxel for targeted therapy of glioma显示文摘The blood–brain barrier(BBB) and the poor ability of many drugs to cross that barrier greatly limits the efficacy of chemotherapies for glioblastoma multiforme(GBM). The present study exploits albumin as drug delivery vehicle to promote the chemotherapeutic efficacy of paclitaxel(PTX) by improving the stability and targeting efficiency of PTX/albumin nanoparticles(NPs). Here we characterize PTX-loaded human serum albumin(HSA) NPs stabilized with intramolecular disulfide bonds and modified with substance P(SP) peptide as the targeting ligand. The fabricated SP-HSA-PTX NPs exhibited satisfactory drug-loading content(7.89%) and entrapment efficiency(85.7%) with a spherical structure(about 150 nm) and zeta potential of -12.0 mV. The in vitro drug release from SP-HSA-PTX NPs occurred in a redox-responsive manner. Due to the targeting effect of the SP peptide, cellular uptake of SP-HSA-PTX NPs into brain capillary endothelial cells(BCECs) and U87 cells was greatly improved.The low IC_(50), prolonged survival period and the obvious pro-apoptotic effect shown by TUNEL analysis all demonstrated that the fabricated SP-HSA-PTX NPs showed a satisfactory anti-tumor effect and could serve as a novel strategy for GBM treatment. | Chunhui Ruan Lisha Liu Yifei Lu Yu Zhang Xi He Xinli Chen Yujie Zhang Qinjun Chen Qin Guo Tao Sun Chen Jiang | 2018 | Acta Pharmaceutica Sinica B2018，8，1： | 19 |
| 2 | Jianpijiedu Fang improves survival of hepatocarcinoma mice by affecting phosphatase and tensin homolog, phosphoinositide 3-kinase, and focal adhesion kinase显示文摘OBJECTIVE: To investigate the effect of Jianpijiedu Fang (JPJDF) on phosphatase and tensin homolog (PTEN), phosphoinositide 3-kinase (PI3K), and focal adhesion kinase (FAK), and on the survival of hepatocellular carcinoma (HCC) nude mice. METHODS: Forty male nude mice were randomly divided into 4 groups. Human HCC tissue was implanted in the livers of three groups. After 24 h, the three groups were treated respectively with JPJDF (37.5 g/kg), saline (20 mL/kg) and Tegafur (FT-207, 160 mg/kg) once a day for 10 weeks. The control group without implanting the tissue was concurrently treated with saline (20 mL/kg). The survival data and body weight of all mice were recorded, and expression levels of PTEN, PI3K and FAK in normal tissue and cancer tissue of the livers were eval-uated with immunohistochemical method. RESULTS: The cumulative survival rate of the mice in the JPJDF group was higher than those of the other groups. The rate of weight loss was the lowest in JPJDF group. The survivability and weight loss rate in FT-207 group were the poorest in all groups. The expression intensity of PTEN was higher in normal tissues than in cancer tissues, and lower in the normal tissues of HCC models than in that of mice without HCC. The PTEN expression intensity in normal tissue and cancer tissue from mice treated with FT-207 were lower than that from the mice treated with JPJDF or saline.The expression intensity of PI3K was higher in cancer tissue than in normal tissue. The PI3K expression intensity was the lowest in normal tissue and cancer tissue from mice treated with JPJDF, and the intensity from mice treated with FT-207 was the highest. In mice treated with JPJDF, the expression intensity of FAK was higher in the normal tissue and lower in the cancer tissue than those of the other treatment groups. CONCLUSION: The mechanism accounting for the prolonged survival of HCC-bearing mice treated with JPJDF might be related to the reduction in weight loss and the benign regulation of PTEN, PI3K, and FAK. | Baoguo Sun Jun Meng Ting Xiang Zexiong Chen Yulong Li Lisha Lu Shijun Zhang Xiaolin Chen | 2013 | Journal of Traditional Chinese Medicine2013，33，4： | 12 |
| 3 | Diagnostic value of 5 serum biomarkers for hepatocellular carcinoma with different epidemiological backgrounds:A large-scale,retrospective study显示文摘Objective:Hepatocellular carcinoma(HCC)is a lethal global disease that requires an accurate diagnosis.We assessed the potential of 5 serum biomarkers(AFP,AFU,GGT-II,GPC3,and HGF)in the diagnosis of HCC.Methods:In this retrospective study,we measured the serum levels of each biomarker using ELISAs in 921 participants,including 298 patients with HCC,154 patients with chronic hepatitis(CH),122 patients with liver cirrhosis(LC),and 347 healthy controls from 3 hospitals.Patients negative for hepatitis B surface antigen and hepatitis C antibody(called'NBNC-HCC')and patients positive for the above indices(called'HBV-HCC and HCV-HCC')were enrolled.The selected diagnostic model was constructed using a training cohort(n=468),and a validation cohort(n=453)was used to validate our results.Receiver operating characteristic analysis was used to evaluate the diagnostic accuracy.Results:Theα-L-fucosidase(AFU)/α-fetoprotein(AFP)combination was best able to distinguish NBNC-HCC[area under the curve:0.986(95%confidence interval:0.958–0.997),sensitivity:92.6%,specificity:98.9%]from healthy controls in the test cohort.For screening populations at risk of developing HCC(CH and LC),the AFP/AFU combination improved the diagnostic specificity for early-stage HCC[area under the curve:0.776(0.712–0.831),sensitivity:52.5%,specificity:91.6%in the test group].In all-stage HBV-HCC and HCV-HCC,AFU was also the best candidate biomarker combined with AFP[area under the curve:0.835(0.784–0.877),sensitivity 69.1%,specificity:87.4%in the test group].All results were verified in the validation group.Conclusions:The AFP/AFU combination could be used to identify NBNC-HCC from healthy controls and hepatitis-related HCC from at-risk patients. | Dongming Liu Yi Luo Lu Chen Liwei Chen Duo Zuo Yueguo Li Xiaofang Zhang Jing Wu Qing Xi Guangtao Li Lisha Qi Xiaofen Yue Xiehua Zhang Zhuoyu Sun Ning Zhang Tianqiang Song Wei Lu Hua Guo | 2021 | Cancer Biology & Medicine2021，18，1： | 10 |
| 4 | Neuroprotective effects of total saponins from Rubus parvifolius L. on cerebral ischemia/reperfusion injury in rats显示文摘This study examines the neuroprotective effects and mechanisms of action of total saponins from Rubus parvifolius L. (TSRP) on focal cerebral ischemia and reperfusion injury in rats. Focal cerebral ischemia and reperfusion injury was performed in rats using the suture method. The results indicate that intragastric injection of TSRP, at 5, 10 and 20 mg/kg, could decrease neurological impairment, reduce cerebral infarct volume, diminish pathological changes, and significantly inhibit the apoptosis of neurons surrounding the ischemic area. In addition, TSRP upregulated the expression of the anti-apoptotic factor Bcl-2, at the protein and mRNA levels, and it downregulated the expression of the pro-apoptotic factor Bax, at the protein and mRNA levels. These findings indicate that TSRP protects against cerebral ischemia/reperfusion injury, and that it may do so by regulating the expression of Bcl-2 and Bax. | Jisheng Wang Fang Zhang Li Tang Liqiong Sun Xiaolin Song] Lisha Cao Zongyin Qiu Chenglin Zhou | 2012 | Neural Regeneration Research2012，7，3： | 5 |
| 5 | CPI-17-mediated contraction of vascular smooth muscle is essential for the development of hypertension in obese mice显示文摘Several factors have been implicated in obesity-related hypertension, but the genesis of the hypertension is largely unknown. In this study, we found a significantly upregulated expression of CPI-17(C-kinasepotentiated protein phosphatase 1 inhibitor of 17 kDa) and protein kinase C(PKC) isoforms in the vascular smooth muscles of high-fat diet(HFD)-fed obese mice. The obese wild-type mice showed a significant elevation of blood pressure and enhanced calcium-sensitized contraction of vascular smooth muscles. However, the obese CPI-17-deficient mice showed a normotensive blood pressure, and the calcium-sensitized contraction was consistently reduced. In addition, the mutant muscle displayed an abolished responsive force to a PKC activator and a 30%-50% reduction in both the initial peak force and sustained force in response to various G protein-coupled receptor(GPCR) agonists. Our observations showed that CPI-17-mediated calcium sensitization is mediated through a GPCR/PKC/CPI-17/MLCP/RLC signaling pathway. We therefore propose that the upregulation of CPI-17-mediated calcium-sensitized vasocontraction by obesity contributes to the development of obesity-related hypertension. | Jie Sun Tao Tao Wei Zhao Lisha Wei Fan She Pei Wang Yeqiong Li Yanyan Zheng Xin Chen Wei Wang Yanning Qiao Xue-Na Zhang Min-Sheng Zhu | 2019 | Journal of Genetics and Genomics2019，46，3： | 4 |
| 6 | Improvement in the risk assessment of oral leukoplakia through morphology-related copy number analysis显示文摘Oral leukoplakia is the most common type of oral potentially malignant disorders and considered a precursor lesion to oral squamous cell carcinoma.However,a predictor of oral leukoplakia prognosis has not yet been identified.We investigated whether copy number alteration patterns may effectively predict the prognostic outcomes of oral leukoplakia using routinely processed paraffin sections.Comparison of copy number alteration patterns between oral leukoplakia with hyperplasia(HOL,n=22)and dysplasia(DOL,n=21)showed that oral leukoplakia with dysplasia had a higher copy number alteration rate(86%)than oral leukoplakia with hyperplasia(46%).Oral leukoplakia with dysplasia exhibited a wider range of genomic variations across all chromosomes compared with oral leukoplakia with hyperplasia.We also examined a retrospective cohort of 477 patients with oral leukoplakia with hyperplasia with detailed follow-up information.The malignant transformation(MT,n=19)and leukoplakia recurrence(LR,n=253)groups had higher frequencies of aneuploidy events and copy number loss rate than the free of disease(FD,n=205)group.Together,our results revealed the association between the degree of copy number alterations and the histological grade of oral leukoplakia and demonstrated that copy number alteration may be effective for prognosis prediction in oral leukoplakia patients with hyperplasia. | Xiaotian Li Lu Liu Jianyun Zhang Ming Ma Lisha Sun Xuefen Li Heyu Zhang Jianbin Wang Yanyi Huang Tiejun Li | 2021 | Science China(Life Sciences)2021，64，9： | 2 |
| 7 | The Inhibitory Effect of Endostatin and Doxycycline Administration on B16 Melanoma Angiogenesis and Cellular Proliferation显示文摘OBJECTIVE To investigate the effect of endostatin and doxycycline on melanoma cellular proliferation and tumor angiogenesis.METHODS The effects of endostatin and doxycycline were studied in mice transplanted with B16 melanoma cells.The mice were divided into 4 groups that were treated as follows:endostatin treatment(E group),doxycycline treatment(D group),endostatin plus doxycycline trearment(DE group),controls(C group) received no treatment.Following 9 days of treatment the tumor tissue was removed to compare the differences in the tumor necrotic rate and micro-vessel density(MVD) among the different groups.Immunohistochemical staining was conducted to detect the expression of proliferating cell nuclear antigen(PCNA)in the di?erent groups. RESULTS The MVD of the 3 experimental groups was significantly less than the control group,(F=10.888,P<0.05),indicating that doxycycline and endostatin can inhibit tumor angiogenesis by decreasing the tumor blood supply.This effect results in inhibition of tumor cellular proliferation and promotion of tumor cell necrosis.The tumor cell necrotic rate of the 3 experimental groups were all significantly higher than the C group(F=7.229,P<0.05) and the difference between the DE and C groups also was statistically significant.PCNA expression in all 3 experimental groups was statistically less than the C group(F=17.729,P<0.05). CONCLUSION The combined use of endostatin and doxycycline in vivo can influence PCNA expression and angiogenesis in melanoma,and significantly inhibit melanoma cellular proliferation. | Lisha Qi Shiwu Zhang Dan fang Zhang Xiaojin Yin Sen Wang Baochun Sun | 2008 | Chinese Journal of Clinical Oncology2008，5，3： | 1 |

| 13 | FSIP1 enhances the therapeutic sensitivity to CDK4/6 inhibitors in triple-negative breast cancer patients by activating the Nanog pathway显示文摘CDK4/6 inhibitors are routinely recommended agents for the treatment of advanced HR+HER2-breast cancer.However,their therapeutic effectiveness in triple-negative breast cancer(TNBC)remains controversial.Here,we observed that the expression level of fibrous sheath interacting protein 1(FSIP1)could predict the treatment response of TNBC to CDK4/6 inhibitors.High FSIP1 expression level was related to a poor prognosis in TNBC,which was associated with the ability of FSIP1 to promote tumor cell proliferation.FSIP1 downregulation led to slowed tumor growth and reduced lung metastasis in TNBC.FSIP1knockout caused cell cycle arrest at the G0/G1 phase and reduced treatment sensitivity to CDK4/6 inhibitors by inactivating the Nanog/CCND1/CDK4/6 pathway.FSIP1 could form a complex with Nanog,protecting it from ubiquitination and degradation,which may facilitate the rapid cell cycle transition from G0/G1 to S phase and exhibit enhanced sensitivity to CDK4/6 inhibitors.Our findings suggest that TNBC patients with high FSIP1 expression levels may be suitable candidates for CDK4/6 inhibitor treatment. | Guanglei Chen Lisha Sun Xi Gu Liping Ai Jie Yang Zhan Zhang Pengjie Hou Yining Wang Xunyan Ou Xiaofan Jiang Xinbo Qiao Qingtian Ma Nan Niu Jinqi Xue Hao Zhang Yongliang Yang Caigang Liu | 2023 | Science China(Life Sciences)2023，66，12： | 1 |
| 14 | Distinct functions of Trio GEF domains in axon outgrowth of cerebellar granule neurons显示文摘As a critical guanine nucleotide exchange factor(GEF) regulating neurite outgrowth, Trio coordinates multiple processes of cytoskeletal dynamics through activating Rac1, Cdc42 and RhoA small GTPases by two GEF domains, but the in vivo roles of these GEF domains and corresponding downstream effectors have not been determined yet. We established multiple lines of knockout mice and assessed the respective roles of Trio GEF domains and Rac1 in axon outgrowth. Knockout of total Trio in cerebellar granule neurons(CGNs) led to an impaired F-actin rearrangement of growth cone and hence a retarded neurite outgrowth. Such a retardation was reproduced by inhibition of GEF1 domain or knockdown of Cdc42 and restored apparently by introduction of active Cdc42. As Rac1 deficiency did not affect the neurite outgrowth of CGNs, we suggested that Trio GEF1-mediated Cdc42 activation was required for neurite outgrowth. We established a GEF2-knockout line with deletion of all Trio isoforms except a cerebella-specific Trio8, a short isoform of Trio without GEF2 domain, and used this line as a GEF2-deficient animal model. The GEF2-deficient CGNs had a normal neurite outgrowth but abolished Netrin-1-promoted growth, without affecting Netrin-1 induced Rac1 activation. We thus suggested that Trio GEF1-mediated Cdc42 activation rather than Rac1 activation drives the F-actin dynamics necessary for neurite outgrowth, while GEF2 functions in Netrin-1-promoted neurite elongation. Our results delineated the distinct roles of Trio GEF domains in neurite outgrowth, which is instructive to understand the pathogenesis of clinical Trio-related neurodevelopmental disorders. | Tao Tao Jie Sun Yajing Peng Pei Wang Xin Chen Wei Zhao Yeqiong Li Lisha Wei Wei Wang Yanyan Zheng Ye Wang Xuena Zhang Min-Sheng Zhu | 2019 | Journal of Genetics and Genomics2019，46，2： | 1 |
| 15 | Nano Fe_(2)O_(3)embedded in montmorillonite with citric acid enhanced photocatalytic activity of nanoparticles towards diethyl phthalate显示文摘Nano-Fe_(2)O_(3)embedded in montmorillonite particles(Fe-Mt)were prepared to degrade diethyl phthalate(DEP)with citric acid(CA)under xenon light irradiation.Compared to pristine montmorillonite(Na-Mt),the embedding process increased 14.5-fold of iron content and 1.8-fold of specific surface area.The synthesized Fe-Mt have more oxygen vacancies than Fe_(2)O_(3)nanoparticles(nFe_(2)O_(3)),which could induce more reactive oxygen species(ROSs)generation in the presence of CA under xenon lamp irradiation.Fe-Mt with CA enhanced photo-assisted degradation of DEP 2.5 times as compared to nFe_(2)O_(3)with CA.Quenching experiments,electron paramagnetic resonance(EPR)spectroscopy and identification of products confirmed that surface-bound·OH was the main radical to degrade DEP.Common anions(i.e.,NO_(3)-,CO_(3)^(2-),Cl^-)and humic acid could compete·OH with DEP and cause slower degradation of DEP.The removal efficiency of DEP was more than 56%with Fe-Mt after three recycles,and the dissolved Fe concentration from Fe-Mt was below 75μmol/L,indicating Fe-Mt had a good stability as a catalyst.Fe-Mt together with CA appeared to be a promising strategy to remove organic pollutants in surface water,or topsoil under solar irradiation. | Zhaoyue Sun Lisha Feng Guodong Fang Longgang Chu Dongmei Zhou Juan Gao | 2021 | Journal of Environmental Sciences2021，33，3： | 1 |
