Insights

Long non-coding RNA ADAMTS9-AS1 inhibits ferroptosis in epithelial ovarian cancer (EOC) by targeting the microRNA-587/solute carrier family 7 member 11 axis, offering a potential therapeutic target for EOC treatment.

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • Epithelial ovarian cancer (EOC) is the leading cause of gynecological cancer mortality.
  • Understanding EOC molecular mechanisms is crucial for improved diagnostics and treatments.

Purpose of the Study:

  • To investigate the role of long non-coding RNA ADAMTS9-AS1 (ADAMTS9-AS1) in regulating solute carrier family 7 member 11 (SLC7A11) expression and ferroptosis in EOC.
  • To elucidate the mechanism involving microRNA-587 (miR-587) sponging by ADAMTS9-AS1.

Main Methods:

  • Quantitative real-time polymerase chain reaction (qRT-PCR) and western blotting to assess gene expression.
  • Cell function assays and ferroptosis marker detection.
  • Dual-luciferase reporter gene and RNA immunoprecipitation assays to confirm molecular interactions.

Main Results:

  • ADAMTS9-AS1 expression was elevated in EOC cells.
  • Knocking down ADAMTS9-AS1 increased miR-587 and decreased SLC7A11 expression, inhibiting proliferation and migration by promoting ferroptosis.
  • ADAMTS9-AS1 directly sponged miR-587, which in turn targeted SLC7A11.

Conclusions:

  • ADAMTS9-AS1 attenuates ferroptosis in EOC by targeting the miR-587/SLC7A11 axis.
  • ADAMTS9-AS1 represents a potential therapeutic target for epithelial ovarian cancer.

MicroRNAs

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...

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...

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...

siRNA - Small Interfering RNAs

Small interfering RNAs, or siRNAs, are short regulatory RNA molecules that can silence genes post-transcriptionally, as well as the transcriptional level in some cases. siRNAs are important for protecting cells against viral infections and silencing transposable genetic elements.
In the cytoplasm, siRNA is processed from a double-stranded RNA, which comes from either endogenous DNA transcription or exogenous sources like a virus. This double-stranded RNA is then cleaved by the...
