Summary
This summary is machine-generated.Glioblastoma-downregulated RNA (GLIDR) is a key factor in non-small cell lung cancer (NSCLC) drug resistance. Targeting GLIDR and its miR-342-5p/PPARGC1A pathway may improve cisplatin treatment outcomes for NSCLC patients.
Area Of Science
- Oncology
- Molecular Biology
- Genetics
Background
- Non-small cell lung cancer (NSCLC) presents a major challenge in cancer mortality due to drug resistance.
- Long non-coding RNAs (lncRNAs) are critical regulators in NSCLC progression and potential therapeutic targets.
- Understanding lncRNA regulatory mechanisms is vital for developing effective NSCLC treatments.
Purpose Of The Study
- To identify effective lncRNAs for NSCLC treatment.
- To investigate the role of identified lncRNAs in NSCLC and cisplatin resistance.
- To elucidate the regulatory pathways involved in NSCLC progression and drug resistance.
Main Methods
- RNA-sequencing analysis of 149 lung adenocarcinoma (LUAD) patients (130 responders, 19 nonresponders).
- Investigated the effects and regulatory pathways of selected lncRNAs on NSCLC and cisplatin resistance.
- Utilized bioinformatic analysis and luciferase assays to confirm molecular interactions.
Main Results
- Glioblastoma-downregulated RNA (GLIDR) was identified as a highly expressed lncRNA in nonresponsive and cisplatin-resistant NSCLC.
- GLIDR knockdown enhanced cisplatin sensitivity and reduced malignancy in NSCLC cells.
- GLIDR sponges microRNA-342-5p (miR-342-5p), regulating Peroxisome proliferator-activated receptor-gamma coactivator-1alpha (PPARGC1A) expression, a key pathway in cisplatin resistance.
Conclusions
- GLIDR serves as a prognostic marker and therapeutic target for cisplatin-resistant NSCLC.
- The miR-342-5p/PPARGC1A axis, regulated by GLIDR, is crucial for NSCLC progression and cisplatin resistance.
- Targeting GLIDR offers a promising strategy for overcoming drug resistance in NSCLC.

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...
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...
