Opis:
Nervous system is characterized by its uniqueness in cells origin, their variability, electrical properties of the nervous cell membrane, response to external signals, neuronal network and changes in synapses activity that are the basis of higher brain functions, such as learning and memory. Brain is a superior organ of human body with an extremely efficient regulation system. Apart from protein and small-molecule regulators, ribonucleic acids (RNAs), especially noncoding proteins (ncRNAs), play a crucial controlling role in the brain. They are present in every cell, from bacteria to primates and have regulatory, catalytic as well as structural function. Many specific ncRNAs have been identified in human brain, responsible for development and functioning. Disturbances in ncRNA synthesis and mechanism of action are connected to diseases such as autism, schizophrenia, Alzheimer disease, Prader-Willi syndrome and others.

Opis:
Long non-coding RNAs (lncRNAs) are a class of intensely studied, yet enigmatic molecules that make up a substantial portion of the human transcriptome. In this work, we link the origins and functions of some lncRNAs to retroposition, a process resulting in the creation of intronless copies (retrocopies) of the so-called parental genes. We found 35 human retrocopies transcribed in antisense and giving rise to 58 lncRNA transcripts. These lncRNAs share sequence similarity with the corresponding parental genes but in the sense/antisense orientation, meaning they have the potential to interact with each other and to form RNA:RNA duplexes. We took a closer look at these duplexes and found that 10 of the lncRNAs might regulate parental gene expression and processing at the pre-mRNA and mRNA levels. Further analysis of the co-expression and expression correlation provided support for the existence of functional coupling between lncRNAs and their mate parental gene transcripts.

Opis:
The biogenesis of plant mitochondria and plastids is a multistep process that depends on the expression of both, organellar and nuclear genes. A growing body of evidence suggests that the indispensable coordination of different steps in this process may be gained by participation of the non-coding RNAs. A plethora of non-coding RNAs of diverse length, both intraorganellar ones, as well as encoded by the nuclear genome (including microRNAs and short interfering RNAs), were also suggested to play a role in the stress response by regulating the expression levels of targeted genes important for organelle biogenesis. Selected points of current interest regarding the regulation of plant mitochondrial and plastid gene expression by diverse non-coding RNAs, also discussed in the aspect of abiotic stress conditions, are highlighted here.
