Summary
The H19 long non-coding RNA (lncRNA) promotes glioma progression by regulating miR-675. This signaling pathway is crucial for high-grade gliomas, offering new therapeutic targets.
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- The long non-coding RNA (lncRNA) H19 is implicated as an oncogene in breast and colon cancers.
- The specific role of H19 in glioma development is not well understood.
Purpose of the Study:
- To investigate the function and mechanism of H19/miR-675 signaling in glioma progression.
- To determine the relationship between H19, miR-675, and Cadherin 13 in glioma cells.
Main Methods:
- Analysis of glioma gene expression datasets.
- RNA interference (siRNA) to deplete H19 expression.
- Bioinformatics and luciferase reporter assays to confirm target interactions.
- Cell invasion assays.
Main Results:
- H19 expression is elevated in high-grade gliomas.
- H19 depletion inhibits glioma cell invasion and reduces miR-675 levels.
- miR-675 directly targets Cadherin 13 (CDH13) in glioma cells.
- Restoration of miR-675 rescues the anti-invasive effect of H19 knockdown.
Conclusions:
- H19/miR-675 signaling is critical for glioma progression.
- H19 promotes glioma invasion by upregulating miR-675, which targets Cadherin 13.
- This study elucidates a novel lncRNA-miRNA regulatory network in glioma development.

7.5K
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...

3.0K
MicroRNA (miRNA) are short, regulatory RNA transcribed from introns (non-coding regions of a gene) or intergenic regions (stretches of DNA present between genes). Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself, forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After the pre-miRNA...

4.0K
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...
