Non-coding RNA in fly dosage compensation.
نویسندگان
چکیده
Dosage compensation modulates global expression of an X chromosome and is necessary to restore the balance between X-chromosome and autosome expression in both sexes. A central question in the field is how this regulation is directed. Large non-coding RNAs, such as Xist in mammals and roX in flies, have pivotal roles in targeting chromosome-wide modification for dosage compensation. Several recent studies in Drosophila provide new insight into the principles of X-chromosome recognition and the function of non-coding RNA in this process.

The influence of non-coding RNAs on allele-specific gene expression in mammals.
Current research has revealed that the influence of RNA molecules on gene expression reaches beyond the realm of protein synthesis back into the nucleus, where it not only dictates the transcriptional activity of genes, but also shapes the chromatin architecture of extensive regions of DNA. Non-coding RNA, in the context of this review, refers to transcripts expressed and processed in the nucle...
متن کاملRole of long non-coding RNA in cells: Example of the H19/IGF2 locus
In the past decade, studies of non-coding RNAs increase. Non-coding RNAs are divided in two classes: small and long non-coding RNA. It was shown that long non-coding RNAs regulate expression of 70% of genes. Long non-coding RNAs are involved in several cellular processes like epigenetic regulation, dosage compensation, alternative splicing and stem cells maintenance for example. Misregulations ...
متن کاملStructure-function analysis of the RNA helicase maleless
Loss of function of the RNA helicase maleless (MLE) in Drosophila melanogaster leads to male-specific lethality due to a failure of X chromosome dosage compensation. MLE is presumably involved in incorporating the non-coding roX RNA into the dosage compensation complex (DCC), which is an essential but poorly understood requirement for faithful targeting of the complex to the X chromosome. Seque...
متن کاملThe evolution of dosage-compensation mechanisms.
Dosage compensation is the process by which the expression levels of sex-linked genes are altered in one sex to offset a difference in sex-chromosome number between females and males of a heterogametic species. Degeneration of a sex-limited chromosome to produce heterogamety is a common, perhaps unavoidable, feature of sex-chromosome evolution. Selective pressure to equalize sex-linked gene exp...
متن کاملStructural and Functional Differences in the Long Non-Coding RNA Hotair in Mouse and Human
Long non-coding RNAs regulate various biological processes such as dosage compensation, imprinting, and chromatin organization. HOTAIR, a paradigm of this new class of RNAs, is localized within the human HOXC gene cluster and was shown, in human cells, to regulate HOXD genes in trans via the recruitment of Polycomb Repressive Complex 2 (PRC2), followed by the trimethylation of lysine 27 of hist...
