SOAT1 and cancer: Although it is difficult to establish a frontier, the study of the mode of action of multiple human viruses revealed that proteostasis, signaling (e.g., JAK-STAT pathway, which acts downstream of IFN-α/β), transport, and RNA metabolism are host functions preferentially targeted by RNA viruses, while transcription, proteostasis, macromolecular assembly, DNA and RNA metabolism, and cell cycle (e.g., cancer pathways) are the affected by DNA viruses14.
