Abstract
BACKGROUND
The present study aimed to explore the impact of sulforaphane on the growth of sSCC cells, and the activation of miR-199a-5p/Sirt1 and CD44ICD signaling pathways.
METHODS
Cell viability, count, apoptosis, and invasion assays were performed in the sSCC cell line (SCC-13) in which miR-199a-5p was over-expressed or under-expressed. The expression levels of miR-199a-5p, Sirt1 and CD44ICD mRNA were measured by quantitative real-time polymerase chain reaction (qRT-PCR).
RESULTS
Sulforaphane significantly inhibited the cell growth and invasion of SCC-13 cells, and dramatically induced cell apoptosis. Additionally, sulforaphane also greatly increased miR-199a-5p expression and suppressed Sirt1 and CD44ICD mRNA levels. Moreover, miR-199a-5p overexpression considerably down-regulated the expressions of Sirt1 and CD44ICD mRNA, and promoted the ability of sulforaphane to represses cell growth and invasion, and to induce cell apoptosis. However, miR-199a-5p underexpression has the opposite effects.
CONCLUSIONS
Sulforaphane appears to inhibit sCC progression by impacting its growth and invasion ability, and regulates miR-199a-5p/Sirt1 and CD44ICD signaling pathways, and may be utilized to develop a curative approach for sSCC.
