| 1 | Engineering an enthesis-like graft for rotator cuff repair:An approach to fabricate highly biomimetic scaffold capable of zone-specifically releasing stem cell differentiation inducers显示文摘Rotator cuff(RC)attaches to humerus across a triphasic yet continuous tissue zones(bone-fibrocartilage-tendon),termed“enthesis”.Regrettably,rapid and functional enthesis regeneration is challenging after RC tear.The existing grafts bioengineered for RC repair are insufficient,as they were engineered by a scaffold that did not mimic normal enthesis in morphology,composition,and tensile property,meanwhile cannot simultaneously stimulate the formation of bone-fibrocartilage-tendon tissues.Herein,an optimized decellularization approach based on a vacuum aspiration device(VAD)was developed to fabricate a book-shaped decellularized enthesis matrix(O-BDEM).Then,three recombinant growth factors(CBP-GFs)capable of binding collagen were synthesized by fusing a collagen-binding peptide(CBP)into the N-terminal of BMP-2,TGF-β3,or GDF-7,and zone-specifically tethered to the collagen of O-BDEM to fabricate a novel scaffold(CBP-GFs/O-BDEM)satisfying the above-mentioned requirements.After ensuring the low immunogenicity of CBP-GFs/O-BDEM by a novel single-cell mass cytometry in a mouse model,we interleaved urine-derived stem cell-sheets into this CBP-GFs/O-BDEM to bioengineer an enthesis-like graft.Its high-performance on regenerating enthesis was determined in a canine model.These findings indicate this CBP-GFs/O-BDEM may be an excellent scaffold for constructing enthesis-like graft to patch large/massive RC tears,and provide breakthroughs in fabricating graded interfacial tissue. | Can Chen Qiang Shi Muzhi Li Yang Chen Tao Zhang Yan Xu Yunjie Liao Shulin Ding Zhanwen Wang Xing Li Chunfeng Zhao Lunquan Sun Jianzhong Hu Hongbin Lu | 2022 | Bioactive Materials2022，7，10： | 4 |
| 2 | Use of DNAzymes for cancer research and therapy显示文摘DNAzymes(Dzs) are single-stranded DNA catalysts that specifically cleave the mRNA of targeted genes.Compared with other gene-silencing technologies,such as ribozymes,antisense oligonucleotide and small interference RNA(siRNA),DNAzymes have several advantages,including small molecular weight,diversity,low cost and relative stability in serum.With the evolution of molecular technology,the first DNAzyme was generated in vitro in 1994.From then on,DNAzymes have been studied in order to understand their structures,chemistry and biological applications.Particularly,DNAzymes have been widely applied as a new interference strategy in the treatment of many conditions,including cancer,viral diseases,and cardiovascular diseases.This review mainly summarizes the use of DNAzymes in the areas of cancer research and therapy. | XU ZhiJie YANG LiFang SUN LunQuan CAO Ya | 2012 | Chinese Science Bulletin2012，57，26： | 2 |

| 5 | Role of epidermal growth factor receptor in DNA damage repair显示文摘Many human tumor cells are characterized by overexpression or mutation of epidermal growth factor receptor (EGFR). Emerging evidence indicates that EGFR, as well as some of its downstream components, can translocate to the nucleus and play roles in transcriptional regulation, signaling conduction and repair of DNA double strands breaks (DSBs). EGFR in its nuclear manifestation promotes DSB repair by interacting with proteins including DNA-PK, ATM, Rad51 and BRCA1, involved in DSB repair, via the PI3K-Akt and Ras-Raf-MAPK pathways. DNA damage repair in tumor cells is emerging as an attractive target in radiotherapy and chemotherapy. Interruption of EGFR functions, or those of its downstream components, presents a promising strategy for confounding DNA damage repair in tumor cells. | LU JingChen YANG LiFang TAO YongGuang SUN LunQuan CAO Ya | 2011 | Chinese Science Bulletin2011，56，30： | 1 |

| 9 | CDK11 negatively regulates Wnt/β-catenin signaling in the endosomal compartment by affecting microtubule stability显示文摘Objectives:Improper activation of Wnt/β-catenin signaling has been implicated in human diseases.Beyond the well-studied glycogen synthase kinase 3p(GSK3p)and casein kinase 1(CK1),other kinases affecting Wnt/β-catenin signaling remain to be defined.Methods:To identify the kinases that modulate Wnt/β-catenin signaling,we applied a kinase small interfering RNA(siRNA)library screen approach.Luciferase assays,immunoblotting,and real-time polymerase chain reaction(PCR)were performed to confirm the regulation o f the Wnt/β-catenin signaling pathway by cyclin-dependent kinase 11(CDK11)and to investigate the underlying mechanism.Confocal immunofluorescence,coimmunoprecipitation(co-IP),and scratch wound assays were used to demonstrate colocalization,detect protein interactions,and explore the function of CDK11.Results:CDK11 was found to be a significant candidate kinase participating in the negative control of Wnt/P-catenin signaling.Down-regulation of CDK11 led to the accumulation of Wnt/β-catenin signaling receptor complexes,in a manner dependent on intact adenomatosis polyposis coli(APC)protein.Further analysis showed that CDK11 modulation of Wnt/P-catenin signaling engaged the endolysosomal machinery,and CDK11 knockdown enhanced the colocalization of Wnt/β-catenin signaling receptor complexes with early endosomes and decreased colocalization with lysosomes.Mechanistically,CDK11 was found to function in Wnt/β-catenin signaling by regulating microtubule stability.Depletion of CDK11 down-regulated acetyl-a-tubulin.Moreover,co-IP assays demonstrated that CDK11 interacts with the a-tubulin deacetylase SIRT2,whereas SIRT2 down-regulation in CDK11-depleted cells reversed the accumulation of Wnt/(3-catenin signaling receptor complexes.CDK11 was found to suppress cell migration through altered W nt/β-catenin signaling.Conclusions:CDK11 is a negative modulator of Wnt/β-catenin signaling that stabilizes microtubules,thus resulting in the dysregulation of receptor complex trafficking from early endosomes to lysosomes. | Danmin Ou Lin Chen Jiang He Zhuoxian Rong Jie Gao Liyu Liu Feiyu Tang Jiang Li Yuezhen Deng Lunquan Sun | 2020 | Cancer Biology & Medicine2020，17，2： | 0 |
