Expression Profile of lncRNA NONHSAT040475 in Peripheral Blood Leukocytes of Healthy Persons / 中国实验血液学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the expression profile of lncRNA NONHSAT040475 in peripheral blood leukocytes of healthy persons.</p><p><b>METHODS</b>The peripheral blood mononuclear cells were collected from 10 healthy volunteers, the CD3(+) T cells,CD19(+) B cells,CD56(+) NK cells and granulocytes were purified and sorted by flow cytometry. Then, the expression of lncRNA NONHSAT040475 in peripheral blood leukocyte subsets was detected by real-time quantitative PCR.</p><p><b>RESULTS</b>the expression levels of lncRNA NONHSAT040475 were various in lymphocyte subsets, its expression in B lymphocytes was significantly higher, as compared with T lymphocytes, while the expressions of lncRNA NONHSAT040475 in NK cells and granulocytes were relative low（P<0.01）.</p><p><b>CONCLUSION</b>lncRNA NONHSAT040475 is widely expressed in human peripheral blood leukocytes, and mainly expressed in B lymphocytes, therefore, laying the foundation for further study of B lymphocyte-related diseases. This study has brought a new opportunity for diagnosing and illustrating the molecular mechanism of hematologic disorder or autoimmune disease.</p>
