Ping-pong amplification of a retroviral vector achieves high-level gene expression: human growth hormone production.

abstract：:We previously reported that human cytomegalovirus (HCMV) infection induces endoplasmic reticulum (ER) stress, resulting in activation of the unfolded protein response (UPR). Although some normal consequences of UPR activation (e.g., translation attenuation) are detrimental to viral infection, we have previously shown ...
