ABSTRACT A novel circular RNA, circRNA_1193, which originates from the membrane alanyl aminopeptidase-like gene in silkworms, was explored for its potential function and regulatory mechanism. We validated the presence of circRNA_1193 in Bombyx mori cytoplasmic polyhedrosis virus (BmCPV)-infected silkworm ovary cell line (BmN) cells through a combination of reverse transcription polymerase chain reaction, Northern blotting, and in situ hybridization. CircRNA_1193 exhibited tissue-specific expression, being highly e…
