Short interfering RNA induced generation and translation of stable 5′ mRNA cleavage intermediates

Abstract: Sequence-specific degradation of homologous mRNA is the main mechanism by which short-interfering RNAs (siRNAs) suppress gene expression. Generally, it is assumed that the mRNA fragments resulting from Ago2 cleavage are rapidly degraded, thus making the transcript translation-incompetent. However, the molecular mechanisms involved in the post-cleavage mRNA decay are not completely understood and the fate of cleavage intermediates has been poorly studied. Using specific siRNAs and short-hairpin RNAs (shRNAs) we… Show more

“…HeLa (HPV-18 positive), CasKi (HPV-16 positive), HEK293T, Jurkat cell lines (from American Type Culture Collection), and HeLa-FLAG16E7MYC 44 were cultured in DMEM (Invitrogen) supplemented with 10% heat-inactivated fetal bovine serum (Sigma), and 1% antibiotic mixture of penicillin G, streptomycin sulfate, and L-Glutamine (GIBCO-Invitrogen). The cells were transfected at 70% confluency.…”

“…Приклад карти плазміди, яку застосовують як носій генетичної інформації, зокрема для інтерферуючої РНК у формі «шпильки» [19] Фармакологія та лікарська токсикологія, Том Так само основними недоліками РНК-нтерференції, зумовленої олігонуклеотидами, є як висока вартість, так і неспецифічна токсичність під час трансфекції та короткотривале пригнічення експресії гена-мішені. Подоланням цієї проблеми стали альтернативні для експресування міРНК у клітинах ссавців -ДНК вектори [19]. Загалом ДНК вектори використовують промотор РНК полімерази ІІІ (Pol III) для експресії, короткі дволанцюгові РНК у вигляді інвертованих повторів послідовностей, що містять, так звану, «шпильку» (рис.…”

“…These concerns are justified, given our limited understanding of how Cas9 endonucleases are actually editing the genome, the high frequency of random edits generated, and the possibility of accumulation of mutations. This dilemma is not unique to CRISPR/Cas9 systems; one study investigated the fate of HPV-16 E7 protein after silencing with siRNA and reported that the truncated 5′ end of the targeted protein is still actively expressed after treatment 89 . This observation raises a critical question about the events that follow the editing and whether the generated knockouts (or knock ins) would be associated with any unexpected outcome.…”
