ABSTRACT

Objective:

To investigate the effect of miR-125b targeting Sema4C on STAT3 signaling pathway on invasion and metastasis of non-Hodgkin′s lymphoma.

Methods:

Expression of miR-125b in non-Hodgkin′s lymphoma tissues and cell lines was detected by QT-PCR.Expression of Sema4C in normal lymphocyte tissues and non-Hodgkin′s lymphoma tissues was detected by immunohistochemistry.Dual luciferase effect of miR-125b on the transcriptional activity of Sema4C was examined by the reporter gene system.Transwell invasion assay was used to detect the expression of miR-125b in the non-Hodgkin′s lymphoma cell line NK-92.Scratch test Western blot was used to detect the expression of Sema4C.Western blot was used to detect the protein expression of STAT3 signal pathway after silencing Sema4C.The protein expression of Sema4C was detected by Western blot.

Results:

Expression of miR-125b was significantly lower in non-Hodgkin′s lymphoma tissues than that in normal tissues[(0.48±0.05)% vs (1.59±0.38)%,P<0.05].Sema4C was highly expressed in non-Hodgkin′s lymphoma[(326.25±7.75)% vs (58.75±5.76)%].After overexpression of miR-125b,non-Hodgkin′s lymphoma cells expression level of Sema4C was down-regulated after silencing Sema4C[(326.25±7.75)% vs (58.75±5.76)%],and the expression of JAK and STAT3 protein were down-regulated after miR-125b overexpression[(85.26±6.94)% vs (12.61±4.32)%,P<0.05].The dual luciferase reporter gene system showed that miR-125b could directly regulate the transcriptional activity of Sema4C.

Conclusion:

miR-125b can regulate the invasion and migration of non-Hodgkin′s lymphoma cells by targets the expression of Sema4C.
