Summary
The H19 gene
Area of Science:
- Molecular biology
- Cancer research
- Genetics
Background:
- The H19 gene's product is an untranslated RNA with an undetermined function.
- The H19 gene is implicated in oncofetal development.
Purpose of the Study:
- To investigate the function of H19 RNA.
- To identify genes modulated by H19 RNA.
- To explore the role of H19 RNA in cancer progression.
Main Methods:
- Human cDNA Atlas microarray analysis to detect gene expression changes.
- Cell culture experiments under varying serum conditions.
- Analysis of cell growth advantages and stress responses.
Main Results:
- H19 RNA upregulates genes associated with cell invasion, migration, and angiogenesis.
- H19 RNA confers a growth advantage in serum-poor conditions, but not in rich medium.
- H19-expressing cells show impaired induction of p57(kip2) under serum stress.
Conclusions:
- H19 RNA may promote cancer progression, angiogenesis, and metastasis.
- The H19 gene's role in cellular behavior is context-dependent, particularly concerning serum availability.
- Dysregulation of p57(kip2) induction might be a mechanism through which H19 influences cell survival.

piRNA - Piwi-interacting RNAs
PIWI-interacting RNAs, or piRNAs, are the most abundant short non-coding RNAs. More than 20,000 genes have been found in humans that code for piRNAs while only 2000 genes have been found for miRNAs. piRNAs can act at the transcriptional and post-transcriptional levels and have a vital role in silencing transposable elements present in germ cells. They are also involved in epigenetic silencing and activation. Previously, they were thought to function only in germ cells but new evidence suggests...
lncRNA - 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)...
Exon Recombination
The evolution of new genes is critical for speciation. Exon recombination, also known as exon shuffling or domain shuffling, is an important means of new gene formation. It is observed across vertebrates, invertebrates, and in some plants such as potatoes and sunflowers. During exon recombination, exons from the same or different genes recombine and produce new exon-intron combinations, which might evolve into new genes.

Experimental 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...
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 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.
