Tumors derived from LIMK1/2 knockdown TICs were substantially smaller and showed delayed growth kinetics and more distinct margins than tumors derived from control TICs.
In this study, we reveal that LIMK1 expression is correlated with tumor differentiation, invasion depth, clinical stage, lymph node metastasis, and poor prognosis.
Therefore, this study indicated that dysregulation of p57(kip2) promoted cell migration and invasion through modulation of LIMK/cofilin signaling and suggested this induction of inappropriate cell motility might contribute to promoting tumor cell for metastasis.
We analyzed here the metastatic behavior and tumor cell-induced neovascularization of pancreatic cancer cells in which both LIMK genes were silenced by siRNAs.
