| 1 | miR-125a-3p targets MTA1 to suppress NSCLC cell proliferation, migration, and invasion显示文摘联系转移的基因(MTA1 ) 1 在 non-small-cell 肺癌症(NSCLC ) 与房间生长,转移,和幸存被联系。几份以前的报告证明了 microRNAs 通过在他们的种子区域和目标 mRNA 的 3-untranslated 区域之间的相互作用影响基因表示,导致 post-transcriptional 规定。这研究的目的是识别 miRNAs 由指向 MTA1 在 NSCLC 房间压制恶意。在有 MTA1 的 transfection 模仿以后,二根人的 NSCLC 房间线被量的 RT-PCR 并且西方的弄污为 MTA1 的表示分析。酶记者试金被建立测试在 MTA1 和它的在上游的 miRNAs 之间的直接连接。房间增长被 3-(4,5-dimethylthiazol-2-yl ) 估计 -2,5-diphenyltetrazolium 溴化物试金, 5-ethynyl-2-deoxyuridine 分析,和殖民地形成试金。房间移植和侵略能力被愈合创伤的试金和 transwell 试金评估。miRNA/MTA1 轴被量的 RT-PCR 并且从八个 NSCLC 病人的在样品的西方的弄污也探查。在候选人 miRNAs 之中, miR-125a-3p 被显示 post-transcriptionally 在 NSCLC 房间调整 MTA1。这些数据被酶记者试金增强,除了 MTA1 相反地与在 NSCLC 纸巾的 miR-125a-3p 被相关的示范。而且, miR-125a-3p 被发现禁止 NSCLC 房间增长,移植,和侵略,通过下面调整的 MTA1 的一样的机制。我们的报告证明 miR-125a-3p 通过 MTA1 的下面规定禁止 NSCLC 房间的增长,迁居,和侵略,显示在 NSCLC 的 miR-125a-3p/MTA1 轴的角色,并且可以提供新奇卓见进分子的机制 underpinning 疾病和潜在的治疗学的目标。 | Hong Zhang Xiaoxia Zhu Na Li Dianhe Li Zhou Sha Xiaokang Zheng Haofei Wang | 2015 | Acta Biochimica et Biophysica Sinica2015，47，7： | 9 |
| 2 | Supramolecular complex glycoconjugate vaccine generates self-enhancement effects for carbohydrate antigen delivery显示文摘Targeting delivery of tumor-associated carbohydrate antigen(TACA)-based vaccine to antigen-presenting cells(APCs)mediated by endogenous antibodies can improve the immunogenicity of TACA.However,an essential requirement of this approach is to generate high titers of endogenous antibodies in vivo through pre-immunization,which complicates the immunization procedure and may cause side effects.Herein,we report a new generation of APC-targeting TACA-based supramolecular complex vaccine,assembled by sialyl Thomsen-nouveau-bovine serum albumin-adamantine(sTn-BSA-Ada)and heptavalent rhamnose(Rha)-modifiedβ-cyclodextrin(β-CD)via host-guest interaction.The complex vaccine retained anti-Rha antibodies recruiting capability and facilitated the APCs uptake of the vaccine via the interaction of the Fc-domain with the Fc receptors on APCs.We demonstrate that direct immunization of complex vaccine elicited anti-Rha and anti-sTn specific immune response synchronously,generating a novel self-enhancement effect that can improve the antigen delivery to APCs in high efficacy.The structure-activity relationship(SAR)study proved that complex vaccine 4 with polyethylene glycol 6(PEG 6)linker in host molecule provoked a robust and specific sTn immune response comparable to the pre-immunization approach.The antisera induced by complex vaccine,either through direct immunization or pre-immunization,exhibited equal potency of cytotoxicity against the sTn expression cancer cells.This study provides a general platform for TACA-based vaccines with self-enhancement effects without the need for pre-immunization. | Han Lin Yanchun Li Kun Zhou Dan Li Hangyan Yu Jie Zhao Haofei Hong Zhifang Zhou Zhimeng Wu | 2024 | Chinese Chemical Letters2024，35，2： | 0 |
| 3 | Synthesis of DNP-modified GM3-based anticancer vaccine and evaluation of its immunological activities for cancer immunotherapy显示文摘Tumor-associated carbohydrate antigens(TACAs) are attractive targets for vaccine development. In this context, we described a strategy combining artificial TACA and glycoengineering for cancer vaccine development. A 2,4-ditrophenyl(DNP)-modified GM3 intermediate was synthesized chemoenzymatically and conjugated to keyhole limpet hemocyanin(KLH), and the resulting bioconjugate was tested for its potential as a vaccine candidate. Mice immunological studies revealed that the DNP-modified GM3(GM3-NHDNP) analog elicited strong and rapid immune responses by recruiting anti-DNP antibodies to facilitate the targeted delivery of the vaccine construct to antigen processing cells(APCs). Moreover, the endogenously produced anti-DNP antibodies, together with the elicited antibodies against GM3-NHDNP, may synergistically promote tumor binding and cancer cell death when the cancer cell surfaces are glycoengineered to express the GM3-NHDNP antigen. | Han Lin Haofei Hong Lipeng Feng Jie Shi Zhifang Zhou Zhimeng Wu | 2021 | Chinese Chemical Letters2021，32，12： | 0 |
| 4 | Synthesis and immunological study of a glycosylated wall teichoic acid-based vaccine against Staphylococcus aureus显示文摘Staphylococcus aureus wall teichoic acids(WTAs) are attractive targets for antibacterial vaccine development. In this study, three core glycosylated WTA structure, including α-1,4-Glc NAc, β-1,4-Glc NAc andβ-1,3-Glc NAc modified ribitol phosphates containing a linker are chemically synthesized and conjugated with tetanus toxin(TT) carrier protein as vaccine candidates. In vivo immunological studies demonstrate that the synthesized glycosylated WTAs display high immunogenicity and all conjugates provoke strong immune responses and elicit high levels of specific IgG antibodies against the Glc NAc-modified WTA. Furthermore, antibodies elicited by the vaccine candidates remain the capability to recognize S. aureus cells and display significant opsonophagocytic activity to clear S. aureus. This study demonstrates that the core structure of glycosylated WTAs are effective antigens for constructing anti-S. aureus vaccines to prevent and control S. aureus infections. | Peng Shen Han Lin Yikai Bao Haofei Hong Zhimeng Wu | 2023 | Chinese Chemical Letters2023，34，4： | 0 |
| 5 | MUC1 vaccines usingβ-cyclodextrin grafted chitosan(CS-g-CD)as carrier via host-guest interaction elicit robust immune responses显示文摘We construct MUC1 vaccines usingβ-cyclodextrin grafted chitosan(CS-g-CD)as carrier via host-guest interaction.These vaccines based on non-covalent assembling can provoke robust immune responses,including high level of specific antibodies and cytokines.The induced antibodies can specifically recognize tumor cells and mediate cytotoxicity against tumor cells.These results indicate that CS-g-CD with strong immunostimulatory activities can be a straightforward platform for peptide-based vaccine construction. | Hangyan Yu Han Lin Yuntian Xie Mengyuan Qu Min Jiang Jie Shi Haofei Hong Hongrui Xu Ling Li Guochao Liao Zhimeng Wu Zhifang Zhou | 2022 | Chinese Chemical Letters2022，33，11： | 0 |
