The osteogenic potential of periodontal ligament stem cells (PDLSCs) is significantly decreased in periodontitis microenvironment. However, the mechanism is still unclear. We used Porphyromonas gingivalis lipopolysaccharide (LPS) as a stimulator of PDLSCs to mimic the periodontal inflammatory environment. The mineralization capability was restrained in LPS-stimulated PDLSCs, and the level of miR-148a increased, while the level of Neuropilin 1 (NRP1) decreased. Downregulation of miR-148a could reverse the osteogenesis deficiency of PDLSCs under LPS treatment. In addition, the expression of miR-148a in PDLSCs was negatively correlated with the expression of NRP1. Furthermore, overexpression of NRP1 upregulated the osteogenesis ability of LPS-stimulated PDLSCs, while inhibition of NRP1 eliminated the stimulative effect of miR-148a inhibitor on osteogenic differentiation. These data illustrated that the inflammatory environment mimicked by LPS inhibits osteogenesis by upregulation of miR-148a and subsequent downregulation of NRP1. We also found, compared to healthy periodontal tissues, miR-148a level increased, while NRP1 level decreased in periodontitis tissues. These two phenomena also exist in PDLSCs that come from the upper two types of tissues. To summarize, the decline of osteogenic potential of PDLSCs under inflammatory condition of periodontitis is related to miR-148a\/NRP1 functional axis. This study may provide a novel strategy in the molecular aspect for the therapy of periodontitis.<\/jats:p>","DOI":"10.1089\/cell.2019.0026","type":"journal-article","created":{"date-parts":[[2019,12,6]],"date-time":"2019-12-06T14:44:26Z","timestamp":1575643466000},"page":"314-322","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":20,"title":["Dysfunction of MiR-148a-NRP1 Functional Axis Suppresses Osteogenic Differentiation of Periodontal Ligament Stem Cells Under Inflammatory Microenvironment"],"prefix":"10.1177","volume":"21","author":[{"given":"Liuliu","family":"Bao","sequence":"first","affiliation":[{"name":"Department of Stomatology, Affiliated Hospital of Nantong University, Nantong, China."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiang","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Stomatology, Haian People's Hospital of Jiangsu Province, Nantong, China."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yang","family":"Xu","sequence":"additional","affiliation":[{"name":"Department of Stomatology, Affiliated Hospital of Nantong University, Nantong, China."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Miao","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Stomatology, Affiliated Hospital of Nantong University, Nantong, China."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yihua","family":"Song","sequence":"additional","affiliation":[{"name":"Department of Stomatology, Affiliated Hospital of Nantong University, Nantong, China."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yongchun","family":"Gu","sequence":"additional","affiliation":[{"name":"Department of Stomatology, The First People's Hospital of Wujiang, Affliated Wujiang Hospital of Nantong University, Suzhou, China."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ya","family":"Zheng","sequence":"additional","affiliation":[{"name":"Department of Stomatology, Affiliated Hospital of Nantong University, Nantong, China."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jingwen","family":"Xiao","sequence":"additional","affiliation":[{"name":"Department of Stomatology, Hai Men People's Hospital, Nantong, China."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuzhe","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Stomatology, Affiliated Hospital of Nantong University, Nantong, China."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qiao","family":"Zhou","sequence":"additional","affiliation":[{"name":"Department of Stomatology, Affiliated Hospital of Nantong University, Nantong, China."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jie","family":"Qian","sequence":"additional","affiliation":[{"name":"Department of Stomatology, Affiliated Hospital of Nantong University, Nantong, China."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yi","family":"Liang","sequence":"additional","affiliation":[{"name":"Department of Stomatology, Affiliated Hospital of Nantong University, Nantong, China."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lujun","family":"Ji","sequence":"additional","affiliation":[{"name":"Department of Stomatology, Nantong Tongzhou People's Hospital, Nantong, China."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xingmei","family":"Feng","sequence":"additional","affiliation":[{"name":"Department of Stomatology, Affiliated Hospital of Nantong University, Nantong, China."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2019,12,4]]},"reference":[{"key":"e_1_3_3_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.cell.2009.01.035"},{"key":"e_1_3_3_3_1","doi-asserted-by":"publisher","DOI":"10.1111\/jcmm.12819"},{"key":"e_1_3_3_4_1","doi-asserted-by":"publisher","DOI":"10.14336\/AD.2018.1110"},{"key":"e_1_3_3_5_1","doi-asserted-by":"publisher","DOI":"10.1101\/gr.082701.108"},{"key":"e_1_3_3_6_1","doi-asserted-by":"publisher","DOI":"10.1530\/JME-13-0294"},{"key":"e_1_3_3_7_1","doi-asserted-by":"publisher","DOI":"10.1038\/nrm3838"},{"key":"e_1_3_3_8_1","doi-asserted-by":"publisher","DOI":"10.1111\/prd.12160"},{"key":"e_1_3_3_9_1","first-page":"615486","article-title":"Mechanisms of bone resorption in periodontitis","author":"Hienz S.A.","year":"2015","unstructured":"Hienz S.A., , Paliwal S., , and Ivanovski S.
