| 2 | Rational integration of defense and repair synergy on PEEK osteoimplants via biomimetic peptide clicking strategy显示文摘Polyetheretherketone(PEEK)has been widely used as orthopedic and dental materials due to excellent mechanical and physicochemical tolerance.However,its biological inertness,poor osteoinduction,and weak antibacterial activity make the clinical applications in a dilemma.Inspired by the mussel adhesion mechanism,here we reported a biomimetic surface strategy for rational integration and optimization of anti-infectivity and osteo-inductivity onto PEEK surfaces using a mussel foot proteins(Mfps)-mimic peptide with clickable azido terminal.The peptide enables mussel-like adhesion on PEEK biomaterial surfaces,leaving azido groups for the further steps of biofunctionalizations.In this study,antimicrobial peptide(AMP)and osteogenic growth peptide(OGP)were bioorthogonally clicked on the azido-modified PEEK biomaterials to obtain a dual-effect of host defense and tissue repair.Since bioorthogonal clicking allows precise collocation between AMP and OGP through changing their feeding molar ratios,an optimal PEEK surface was finally obtained in this research,which could long-term inhibit bacterial growth,stabilize bone homeostasis and facilitate interfacial bone regeneration.In a word,this upgraded mussel surface strategy proposed in this study is promising for the surface bioengineering of inert medical implants,in particular,achieving rational integration of multiple biofunctions to match clinical requirements. | Meng Li Jiaxiang Bai Huaqiang Tao Li Hao Weiling Yin Xiaoxue Ren Ang Gao Ning Li Miao Wang Shiyuan Fang Yaozeng Xu Liang Chen Huilin Yang Huaiyu Wang Guoqing Pan Dechun Geng | 2022 | Bioactive Materials2022，7，2： | 2 |
| 3 | Risk SNP-induced lncRNA-SLCCl drives colorectal cancer through activating glycolysis signaling显示文摘Long non-coding RNAs(lncRNAs)play key roles in colorectal carcinogenesis.Here,we aimed to identify the risk SNP-induced lncRNAs and to investigate their roles in colorectal carcinogenesis.First,we identified rs6695584 as the causative SNP in 1 q41 locus.The A>G mutation of rs6695584 created a protein-binding motif of BATF,altered the enhancer activity,and subsequently activated IncSLCCl expression.Further validation in two independent CRC cohorts confirmed the upregulation of IncSLCCl in CRC tissues,and revealed that increased IncSLCCl expression was associated with poor survival in CRC patients.Mechanistically,lncRNA-SLCCl interacted with AHR and transcriptionally activated HK2 expression,the crucial enzyme in glucose metabolism,thereby driving the glycolysis pathway and accelerating CRC tumor growth.The functional assays revealed that IncSLCCl induced glycolysis activation and tumor growth in CRC mediated by HK2.In addition,HK2 was upregulated in colorectal cancer tissues and positively correlated with IncSLCCl expression and patient survival.Taken together,our findings reveal a risk SNP-mediated oncogene lncRNA-SLCCl promotes CRC through activating the glycolysis pathway. | Tingting Yan Chaoqin Shen Penglei Jiang Chenyang Yu Fangfang Guo Xianglong Tian Xiaoqiang Zhu Shiyuan Lu Bingshe Han Ming Zhong Jinxian Chen Qiang Liu Yingxuan Chen Junfang Zhang Jie Hong Haoyan Chen Jing-Yuan Fang | 2021 | Signal Transduction and Targeted Therapy2021，6，3： | 1 |
| 4 | 3D printed porous titanium filled with mineralized UV-responsive chitosan hydrogel promotes cell proliferation and osteogenesis in vitro显示文摘The modification of 3D printed porous titanium(Ti),especially for the internal pore structure,is critical and has received more attention to promoting its osteogenesis for clinical use.Ultra-violet(UV)responsive chitosan(CSMA),as an injectable filling material,was firstly incorporated into porous Ti,and then CSMA was in-situ mineralized by carbon oxide(CO_(2))diffusion(CSMA/CaCO_(3)).Their physical-chemical and biological properties were investigated in vitro.CaCO_(3) crystals within CSMA hydrogels were successfully deposited into pores of porous Ti,which exhibited favorable biocompatibility.Ti implants filled with CSMA/CaCO_(3) promoted adhesion and proliferation of bone mesenchymal stem cells(BMSCs).Moreover,Ti implant filled CSMA/CaCO_(3) hydrogels could increase alkaline phosphatase(ALP)activities,up-regulate osteopontin(OPN)and osteocalcin(OCN)expression levels,and enhance extracellular mineralization.3D printed porous Ti filled with mineralized UV-responsive chitosan hydrogel could promote proliferation and osteogenesis of BMSCs,and have great potential for the modification of porous Ti implants in bone tissue engineering. | Jiazhao Yang Fan Liu Changshun Zhou Hejie Li Gaolin Yang Shiyuan Fang In-Seop Lee Yi Liu Hao Bai Cen Chen | 2023 | Journal of Materials Science & Technology2023，，11： | 0 |
| 5 | Fetuin-A is an immunomodulator and a potential therapeutic option in BMP4-dependent heterotopic ossification and associated bone mass loss显示文摘Heterotopic ossification(HO)is the abnormal formation of bone in extraskeletal sites.However,the mechanisms linking HO pathogenesis with bone mass dysfunction remain unclear.Here,we showed that mice harboring injury-induced and BMP4-dependent HO exhibit bone mass loss similar to that presented by patients with HO.Moreover,we found that injury-induced hyperinflammatory responses at the injury site triggered HO initiation but did not result in bone mass loss at 1 day post-injury(dpi).In contrast,a suppressive immune response promoted HO propagation and bone mass loss by 7 dpi.Correcting immune dysregulation by PD1/PDL1 blockade dramatically alleviated HO propagation and bone mass loss.We further demonstrated that fetuin-A(FetA),which has been frequently detected in HO lesions but rarely observed in HO-adjacent normal bone,acts as an immunomodulator to promote PD1 expression and M2 macrophage polarization,leading to immunosuppression.Intervention with recombinant FetA inhibited hyperinflammation and prevented HO and associated bone mass loss.Collectively,our findings provide new insights into the osteoimmunological interactions that occur during HO formation and suggest that FetA is an immunosuppressor and a potential therapeutic option for the treatment of HO. | Chen Kan Jiazhao Yang Haitao Fan Yuanjuan Dai Xingxing Wang Rui Chen Jia Liu Xiangyue Meng Wei Wang Guiling Li Jiao Zhou Ya Zhang Wanbo Zhu Shiyuan Fang Haiming Wei Hong Zheng Siying Wang Fang Ni | 2022 | Bone Research2022，10，4： | 0 |
