Abstract:
Transcriptome analyses have revealed the existence of a large variety of non-coding RNAs (ncRNAs) that, although specifically expressed, are largely unknown in function. The best-studied role of ncRNAs is the regulation of gene expression, mostly participating in transcription. We report here the role of an antisense ncRNA that represses transcription of LEF1 by recruiting Polycomb repressive complex 2 (PRC2), which trimethylates H3K27. This antisense LEF1 transcript undergoes splicing losing its inhibitory function. We also discuss the possible general relevance of this finding.

Types of RNA
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in the regulation of gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.

siRNA - Small Interfering RNAs
In the cytoplasm, siRNA is processed from a double-stranded RNA, which comes from either endogenous DNA transcription or exogenous sources like a virus. This double-stranded RNA is then cleaved by the...
RNA Interference
This process occurs naturally in cells, often through the activity of genomically-encoded microRNAs. Researchers can take advantage of this mechanism by introducing synthetic RNAs to deactivate specific genes for research or therapeutic purposes. For example, RNAi could be used...
