Over the past 10 years, it has emerged that pervasive transcription in mammalian genomes has a tremendous impact on several biological functions. Most of transcribed RNAs are lncRNAs and repetitive elements. In this review, we will detail the discovery of a new functional class of natural and synthetic antisense lncRNAs that stimulate translation of sense mRNAs. These molecules have been named SINEUPs since their function requires the activity of an embedded inverted SINEB2 sequence to UP-regulate translation. Natural SINEUPs suggest that embedded Transposable Elements may represent functional domains in long non-coding RNAs. Synthetic SINEUPs may be designed by targeting the antisense sequence to the mRNA of choice representing the first scalable tool to increase protein synthesis of potentially any gene of interest. We will discuss potential applications of SINEUP technology in the field of molecular biology experiments, in protein manufacturing as well as in therapy of haploinsufficiencies.

Abstract
Over the past 10 years, it has emerged that pervasive transcription in mammalian genomes has a tremendous impact on several biological functions. Most of transcribed RNAs are lncRNAs and repetitive elements. In this review, we will detail the discovery of a new functional class of natural and synthetic antisense lncRNAs that stimulate translation of sense mRNAs. These molecules have been named SINEUPs since their function requires the activity of an embedded inverted SINEB2 sequence to UP-regulate translation. Natural SINEUPs suggest that embedded Transposable Elements may represent functional domains in long non-coding RNAs. Synthetic SINEUPs may be designed by targeting the antisense sequence to the mRNA of choice representing the first scalable tool to increase protein synthesis of potentially any gene of interest. We will discuss potential applications of SINEUP technology in the field of molecular biology experiments, in protein manufacturing as well as in therapy of haploinsufficiencies.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
