WebJan 21, 2005 · Both intronic miRNA and mRNA are co-expressed in a gene transcript (pre-mRNA) by Pol-II promoters. In the nucleus, the pri-miRNA is excised by Drosha RNase to form a hairpin-like pre-miRNA template and then exported to cytoplasm for further processing by single-stranded RNA-specific Dicer* to form mature miRNAs. WebIn CLL, the inactivation of tumour-suppressor genes by aberrant mRNA processing is substantially more prevalent than the functional loss of such genes through genetic …

To more precisely define the positions from which certain intronic regulatory sequences increase mRNA accumulation, the effect of a UBIQUITIN intron on gene expression was tested from six different positions surrounding the transcription start site (TSS) of a reporter gene fusion in Arabidopsis thaliana.The intron increased …
WebAug 27, 2024 · Researchers at the Sloan Kettering Institute have found that changes in an information-carrying molecule called messenger RNA (mRNA) can inactivate the functions of tumor suppressor genes and thereby promote cancer. The findings pinpoint previously unknown drivers of the disease, indicating that cancer diagnostics need to go beyond the … WebRNA-seq experiments generate reads derived not only from mature RNA transcripts but also from pre-mRNA. Here we present a computational approach called exon-intron split …
