nc886 is a medium-sized non-coding RNA transcribed by RNA polymerase III (Pol III) and has diverse roles in tumorigenesis, innate immunity, and other cellular processes. The expression of nc886 is controlled by multiple mechanisms, including promoter CpG DNA methylation and transcription factor activity. Additionally, its RNA instability contributes to its highly variable expression levels. This comprehensive review discusses nc886's variable expression in physiological and pathological conditions and examines the regulatory factors that determine its expression levels.
nc886 is a medium-sized non-coding RNA that is transcribed by RNA polymerase III (Pol III) and plays diverse roles in tumorigenesis, innate immunity, and other cellular processes. Although Pol III-transcribed ncRNAs were previously thought to be expressed constitutively, this concept is evolving, and nc886 is the most notable example. The transcription of nc886 in a cell, as well as in human individuals, is controlled by multiple mechanisms, including its promoter CpG DNA methylation and transcription factor activity. Additionally, the RNA instability of nc886 contributes to its highly variable steady-state expression levels in a given situation. This comprehensive review discusses nc886's variable expression in physiological and pathological conditions and critically examines the regulatory factors that determine its expression levels.
