| 1 | The Msi1-mTOR pathway drives the pathogenesis of mammary and extramammary Paget’s disease显示文摘Mammary and extramammary Paget’s Diseases(PD)are a malignant skin cancer characterized by the appearance of Paget cells.Although easily diagnosed,its pathogenesis remains unknown.Here,single-cell RNA-sequencing identified distinct cellular states,novel biomarkers,and signaling pathways—including mTOR,associated with extramammary PD.Interestingly,we identified MSI1 ectopic overexpression in basal epithelial cells of human PD skin,and show that Msi1 overexpression in the epidermal basal layer of mice phenocopies human PD at histopathological,single-cell and molecular levels.Using this mouse model,we identified novel biomarkers of Paget-like cells that translated to human Paget cells.Furthermore,single-cell trajectory,RNA velocity and lineage-tracing analyses revealed a putative keratinocyte-to-Paget-like cell conversion,supporting the in situ transformation theory of disease pathogenesis.Mechanistically,the Msi1-mTOR pathway drives keratinocyte-Paget-like cell conversion,and suppression of mTOR signaling with Rapamycin significantly rescued the Paget-like phenotype in Msi1-overexpressing transgenic mice.Topical Rapamycin treatment improved extramammary PD-associated symptoms in humans,suggesting mTOR inhibition as a novel therapeutic treatment in PD. | Yongli Song Christian F.Guerrero-Juarez Zhongjian Chen Yichen Tang Xianghui Ma Cong Lv Xueyun Bi Min Deng Lina Bu Yuhua Tian Ruiqi Liu Ran Zhao Jiuzhi Xu Xiaole Sheng Sujuan Du Yeqiang Liu Yunlu Zhu Shi-jun Shan Hong-duo Chen Yiqiang Zhao Guangbiao Zhou Jianwei Shuai Fazheng Ren Lixiang Xue Zhaoxia Ying Xing Dai Christopher J.Lengner Bogi Andersen Maksim V.Plikus Qing Nie Zhengquan Yu-Show | 2020 | Cell Research2020，30，10： | 2 |

| 5 | An effective pharmacological hydrogel induces optic nerve repair and improves visual function显示文摘Irreversible eye lesions, such as glaucoma and traumatic optic neuropathy, can cause blindness;however, no effective treatments exist. The optic nerve, in particular, lacks the capacity to spontaneously regenerate, requiring the development of an effective approach for optic nerve repair, which has proven challenging. Here, we demonstrate that a combination of the small molecules 3BDO and trichostatin A(TSA)—which regulate mTOR and HDAC, respectively—packaged in thermosensitive hydrogel for 4-week-sustained release after intravitreal injection, effectively induced optic nerve regeneration in a mouse model of optic nerve crush injury. Moreover, this combination of 3BDO and TSA also protected axon projections and improved visual responses in an old mouse model(11 months old) of glaucoma. Taken together, our data provide a new, local small molecule-based treatment for the effective induction of optic nerve repair, which may represent a foundation for the development of pharmacological methods to treat irreversible eye diseases. | Lipeng Wang Shan Zhang Yawen Han Shuo Tang Jiarui Li Lina Bu Dongyu Zhao Hongkui Deng | 2024 | Science China(Life Sciences)2024，67，3： | 0 |
| 6 | miR-195-5p exerts tumor-suppressive functions in human lung cancer cells through targeting TrxR2显示文摘miR-195-5p has been widely explored in various cancers and is considered as a tumor-suppressive microRNA.However,its roles in human lung cancer pathogenesis are not fully elucidated.In this study,we aimed to explore how miR-195-5p is involved in malignant behaviors of lung adenocarcinoma(LUAD)cells.miR-195-5p expression was examined in the tumor tissues of patients with LUAD and human LUAD cell lines including A549 and PC-9.Thioredoxin reductase 2(TrxR2)was predicted to be an mRNA target of miR-195-5p using online tools and validated by the Dual-Luciferase Reporter Assay.Lentivirus infection was used for gene overexpression,while gene knockdown was achieved by RNA interference.Cell proliferation was determined by Cell Counting Kit-8 and 5-ethynyl-2′-deoxyuridine methods,and cell migration and invasion were assayed with transwell experiments.Cell apoptosis was determined by annexin V staining-based flow cytometry.The antitumor effects of miR-195-5p were also evaluated in nude mice xenografted with A549 cells.We found that miR-195-5p was lowly expressed in human LUAD cells,and its overexpression markedly suppressed cell proliferation,migration,and invasion and increased the apoptosis of LUAD cells in vitro.TrxR2 knockdown phenocopied the tumor-suppressive effects of miR-195-5p overexpression,while simultaneous TrxR2 overexpression remarkably reversed the effects of miR-195-5p overexpression on malignant behaviors of A549 and PC-9 cells.Additionally,miR-195-5p overexpression inhibited the growth of xenografted A549 tumor in nude mice.Our work verified that miR-195-5p exerts tumor-suppressive functions in LUAD cells through targeting TrxR2 and suggested that the miR-195-5p/TrxR2 axis is a potential biomarker for LUAD therapy. | Lina Bu Yingxuan Tian Hongqing Wen Weihong Jia Shuanying Yang | 2021 | Acta Biochimica et Biophysica Sinica2021，53，2： | 0 |
