Alteration of 3D genome structure can change cell¡¯s gene expression pattern that causes cellular function change and thus could be used as a novel therapy for treating many diseases including COVID-19. Genotoxic drug is the only drug that could be used to alter 3D genome structure. Since at present no purpose-made non-carcinogenic genotoxic drugs for altering genome structure are available and fighting COVID-19 must be done without delay, it is possible to repurpose some old drugs as non-carcinogenic genotoxic drugs that can be used to reduce target cell¡¯s susceptibility to SARS- CoV-2 which causes COVID-19 and to modulate immune cell¡¯s response to SARS-CoV-2 infection through altering 3D genome structures in target cells and immune cells. %K Three-Dimensional Genome Structure %K Non-Carcinogenic Genotoxic Drugs %K Chloroquine %K Hydroxychloroquine %K SARS-CoV-2 %K Coronavirus Disease 2019 (COVID-19) %U http://www.oalib.com/paper/5435973
