Whole genome microarray of T lymphoma invasion and metastasis (Tiam1) silenced retinoblastoma Y79 cells

We hypothesized that Tiam1 is involved in invassiveness of retinoblastoma. The fuctional role of Tiam1 in cell progression and metastasis was tested by siRNA mediated knockdown of Tiam1 in retinoblastoma Y79 cells. The genes de-regulated in response to Tiam1 knockdown was analysed by cDNA microarray in which most of the actin cytoskeleton regulation proteins and apoptotic proteins were de-regulated. our results prove that Tiam1 modulates actin cytoskeleton and cell invasion in retinoblastoma.
