MIR503HG negatively regulated its target miR-107. MiR-107 overexpression reversed the anti-tumor effects of MIR503HG overexpression on colon cancer cells. Par4 was a target of miR-107, which was positively regulated by MIR503HG. The promoting effects of MIR503HG silencing on colon cancer cells were eliminated by Par4 overexpression.

The nanocomplexes formed by metallodendrimers and different siRNA were examined for their zeta potential and size, and by transmission electron microscopy, fluorescence polarisation, circular dichroism, and electrophoresis. The internalisation of dendriplexes was estimated by flow cytometry and confocal microscopy in a human breast cancer cell line, following the ability of these metallodendrimers to deliver the siRNA into the cell. In vitro cell viability experiments have indicated effective interactions between Cu (II) dendrimers and pro-apoptotic siRNAs: Mcl-1 and Bcl-2 in breast cancer cells.

Activated signaling pathways and cytokine production were evaluated in a panel of human biliary tract cancer (BTC) cell lines. Human peripheral blood mononuclear cells were cultured with BTC supernatants, with and without cytokine neutralising antibodies, and analysed by flow cytometry or immunoblot.
