Our data showed that overexpression of PRRX1 induced EMT and facilitated the invasion and migration of SACC cells, and PRRX1 expression was closely associated with high FFAs level and poor prognosis of SACC patients.
Then, we found that overexpression of miR-642b-3p, one of the most significantly downregulated miRNAs in PRRX1-overexpressed cells, significantly reduced the migration and invasion, and increased cell proliferation and apoptosis.
The present study aimed to examine the effect of peroxiredocin 1 (Prx1) on vascular smooth muscle cell (VSMC) proliferation, invasion and migration abilities, and to examine the effect of Toll‑like receptor 4 (TLR4) gene silencing on VSMC proliferation, invasion and migration induced by the overexpression of Prx1.
Our study demonstrated that miR-655 inhibits the acquisition of the EMT phenotype in TNBC by down-regulating Prrx1, thereby inhibiting cell migration and invasion during cancer progression.
