Abstract:
Objective To study the in vitro cytotoxicity of HRZ (isoniazid + rifampin + pyrazinamide) / transforming growth factor (TGF) β1 siRNA nanoliposomes on human macrophages and the underlying mechanism. Methods Self-made nanoliposomes were used to study with the cultured human macrophages in vitro. MTT assay was used to detect cell proliferation. Flow cytometry was used to analyze apoptosis and cell cycle. Electron microscopy was used to observe autophagy. RT-PCR and Western blot were employed to analyze the silenced expression of target gene TGF-β1. Results HRZ/TGF-β1 siRNA nanoliposomes (triple liposome) inhibited macrophage proliferation within certain range of concentration, and cell cycle was captured in G2 phase. The HRZ / TGF-β1 SiRNA nanoliposomes could significantly inhibit the expression of target gene TGF-β1 in human macrophages. Conclusions The self-made triple liposome has evident effect in silencing the target gene. It is a promising biomaterial, which meets the required specifications in terms of cytotoxicity.
