				        	Objective:To verify that hypoxia induces epithelial mesenchymal transition in HaCaT cells, and to observe the effect of LncRNA HOTAIR on epithelial mesenchymal transition in HaCaT cells.Methods:From Jan. 2018 to Dec. 2018 in Chinese Academy of Medical Science, HaCaT cells were divided into four groups: group A cultured under normoxia, group B cultured under hypoxia, group C transfected with sh-control cultured under hypoxia, and group D transfected with sh-LncRNA HOTAIR cultured under hypoxia. After 36 hours of culturing, the expression of E-cadherin and vimentin were detected using qPCR and Western blot. The migration of HaCaT cells was evaluated by Transwell assay.Results:The relative quantity of E-cadherin mRNA in the four groups were 3.076±0.271, 1.000±0.089, 1.024±0.222, and 2.595±0.085, while vimentin mRNAs were 1.002±0.183, 4.170±0.279, 4.111±0.477, and 2.412±0.134, respectively. In addition, the Transwll invasion assay showed that numbers of cell migration in the four groups were 32.70±3.93, 125.40±6.26, 120.10±6.79, and 58.24±7.06, respectively.Conclusions:The study suggests that hypoxia promotes epithelial mesenchymal transition in keratinocytes. Furthermore, downregulation of HOTAIR is noted to inhibit epithelial mesenchymal transition of keratinocytes under hypoxia condition.
