Summary
Long non-coding RNA RHPN1-AS1 promotes ovarian cancer (OC) progression by sponging miR-1299. Targeting RHPN1-AS1 offers a potential therapeutic strategy for OC patients.
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- Ovarian cancer (OC) poses a significant public health challenge.
- The molecular mechanisms driving OC development and progression require further elucidation.
- The role of long non-coding RNAs (lncRNAs) in OC pathogenesis is not fully understood.
Purpose of the Study:
- To investigate the role of lncRNA RHPN1-AS1 in ovarian cancer.
- To explore the molecular mechanism by which RHPN1-AS1 influences OC progression.
- To identify potential therapeutic targets for OC treatment.
Main Methods:
- Quantitative real-time PCR (qRT-PCR) for gene expression analysis.
- Cell proliferation assays (CCK8, colony formation) and cell migration/invasion assays (Transwell).
- Luciferase reporter and pulldown assays to confirm RNA interactions.
Main Results:
- lncRNA RHPN1-AS1 was found to be highly expressed in OC tissues and correlated with poor prognosis.
- Silencing RHPN1-AS1 inhibited OC cell proliferation, migration, and invasion.
- RHPN1-AS1 was identified to sponge miR-1299, and miR-1299 inhibition reversed the effects of RHPN1-AS1 knockdown.
Conclusions:
- RHPN1-AS1 promotes ovarian cancer progression by sponging miR-1299.
- RHPN1-AS1 represents a potential novel therapeutic target for ovarian cancer.

9.6K
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...

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...

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...

7.4K
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...
