Summary
Long noncoding RNA FGD5 antisense RNA 1 (FGD5-AS1) promotes non-small cell lung cancer (NSCLC) progression by regulating the miR-944/MACC1 axis. Silencing FGD5-AS1 inhibits NSCLC cell viability, migration, and invasion, offering a potential therapeutic target.
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- Long noncoding RNAs (lncRNAs) play crucial roles in cancer development.
- The specific role of FGD5 antisense RNA 1 (FGD5-AS1) in non-small cell lung cancer (NSCLC) remains incompletely understood.
- Investigating lncRNAs like FGD5-AS1 is vital for uncovering novel therapeutic strategies in NSCLC.
Purpose of the Study:
- To elucidate the regulatory mechanism of FGD5-AS1 in NSCLC progression.
- To determine the impact of FGD5-AS1 on NSCLC cell viability, migration, and invasion.
- To identify potential therapeutic targets within the FGD5-AS1 regulatory network.
Main Methods:
- Quantitative real-time PCR (QRT-PCR) to assess gene expression levels.
- Cell viability assays (MTT) and migration/invasion assays (Transwell).
- Dual-luciferase reporter assays to confirm molecular interactions; exosome isolation and characterization.
Main Results:
- FGD5-AS1 and MACC1 expression were elevated in NSCLC, while miR-944 was decreased.
- FGD5-AS1 expression correlated significantly with TNM stage and metastasis.
- FGD5-AS1 knockdown reduced NSCLC cell viability, migration, and invasion via the miR-944/MACC1 pathway, also suppressing M2 macrophage polarization.
Conclusions:
- FGD5-AS1 knockdown attenuates NSCLC progression by modulating the miR-944/MACC1 axis.
- The FGD5-AS1/miR-944/MACC1 pathway represents a promising therapeutic target for NSCLC treatment.
- FGD5-AS1 influences the tumor microenvironment, including macrophage polarization, impacting NSCLC progression.

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...

9.4K
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...

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...

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...
