The role of TF-1 cell apoptosis-related gene 19 in systemic lupus erythematosus / 中国病理生理杂志

AIM: To clarify the role of new apoptosis-related gene, TF-1 cell apoptosis-related gene 19(TFAR19), in the pathogenesis of systemic lupus erythematosis (SLE) and the relationship between TFAR19 and SLE. METHODS: DNA Ladder detection, Western blotting, immunological fluorescence method, ELISA and so on were used to test if ultraviolet B(UVB) could induce HaCaT cell apoptosis and TFAR19 expression. RESULTS: HaCaT cell apoptosis could be detected after 24 hours of 30 mj/cm 2 UVB irradiation. Also, we found that in active SLE patients, the TFAR19 antibody was increased, but not significant compared to the normal control. CONCLUSION: TFAR 19 is involved in the process of UVB induced ketatinocyte line HaCaT apoptosis and SLE pathogenesis.
