Background
- Non-small cell lung cancer (NSCLC) is a leading cause of cancer mortality.
- MiR-489-3p, a microRNA, is downregulated in NSCLC and acts as a tumor suppressor.
- Understanding miR-489-3p's role is key for NSCLC diagnostics and therapeutics.
Purpose Of The Study
- To investigate the molecular mechanisms of miR-489-3p in NSCLC.
- To determine the effect of miR-489-3p on NSCLC cell proliferation and migration.
- To explore the involvement of the PI3K/AKT pathway in miR-489-3p's function.
Main Methods
- Utilized A549 NSCLC cell line for experiments.
- Transfected cells with miR-489-3p mimics/inhibitors and wortmannin.
- Analyzed protein and gene expression via Western blotting and qRT-PCR.
- Assessed cell proliferation and migration using colony formation and wound healing assays.
Main Results
- Overexpression of miR-489-3p significantly inhibited NSCLC cell proliferation and migration.
- Co-transfection with wortmannin enhanced the inhibitory effects of miR-489-3p.
- Elevated HER2, PI3K, and AKT expression observed in lung adenocarcinoma tissues.
Conclusions
- MiR-489-3p overexpression inhibits NSCLC progression by suppressing the HER2/PI3K/AKT/Snail pathway.
- This study provides a basis for developing miR-489-3p-based diagnostic markers and therapeutic strategies for NSCLC.

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...
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...
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...
Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...
Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...
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...
