Summary
Non-protein-coding RNAs (ncRNAs) are crucial for nervous system development. This review highlights their roles in vertebrate retinal cell development, including miRNAs, OSTs, Tug1, and RNCR2.
Area of Science:
- Neuroscience
- Molecular Biology
- Genetics
Background:
- Non-protein-coding RNAs (ncRNAs) are increasingly recognized for their diverse cellular functions.
- ncRNAs play significant roles in regulating gene transcription and translation.
- Their involvement in the nervous system, particularly retinal development, is an emerging area of research.
Purpose of the Study:
- To review recent advances in understanding the role of ncRNAs in vertebrate retinal development.
- To identify specific ncRNAs involved in retinal cell subtype specification and maturation.
- To highlight the potential significance of ncRNAs in retinal cell fate determination.
Main Methods:
- Literature review of recent studies on ncRNAs in vertebrate retinal development.
- Identification and categorization of known and suspected functional ncRNAs.
- Discussion of proposed mechanisms of action for these ncRNAs.
Main Results:
- Several types of ncRNAs, including microRNAs (miRNAs), long noncoding opposite-strand transcripts (OSTs), Tug1, and RNCR2, are implicated in retinal development.
- These ncRNAs are involved in the specification and maturation of various retinal cell subtypes.
- The precise mechanisms by which most ncRNAs function in retinal development remain largely unclear.
Conclusions:
- ncRNAs are essential regulators of vertebrate retinal development.
- Specific ncRNAs like miRNAs, OSTs, Tug1, and RNCR2 are key players in retinal cell fate specification.
- Further research is needed to elucidate the functional mechanisms of ncRNAs in retinal neurogenesis.

02:39lncRNA - Long Non-coding RNAs
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA (lncRNA)...
01:20Types 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 regulating 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.

02:15Experimental RNAi
RNA interference (RNAi) is a cellular mechanism that inhibits gene expression by suppressing its transcription or activating the RNA degradation process. The mechanism was discovered by Andrew Fire and Craig Mello in 1998 in plants. Today, it is observed in almost all eukaryotes, including protozoa, flies, nematodes, insects, parasites, and mammals. This precise cellular mechanism of gene silencing has been developed into a technique that provides an efficient way to identify and determine the...
01:23RNA Interference
RNA interference (RNAi) is a process in which a small non-coding RNA molecule blocks the post-transcriptional expression of a gene by binding to its messenger RNA (mRNA) and preventing the protein from being translated.
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...

02:23RNA Editing
RNA editing is a post-transcriptional modification where a precursor mRNA (pre-mRNA) nucleotide sequence is changed by base insertion, deletion, or modification. The extent of RNA editing varies from a few hundred bases, in mitochondrial DNA of trypanosomes, to a just single base, in nuclear genes of mammals. Even a single base change in the pre-mRNA can convert a codon for one amino acid into the codon for another amino acid or a stop codon. This type of re-coding can significantly affect the...
