Abstract

Insights

Long non-coding RNA LINC00210 enhances osteosarcoma radioresistance by regulating the miR-342-3p/GFRA1 axis. Targeting LINC00210 may improve radiotherapy efficacy for osteosarcoma patients.

Area of Science:

  • Oncology
  • Molecular Biology
  • Radiotherapy Research

Background:

  • Radiotherapy is a key strategy against osteosarcoma metastasis.
  • Cancer radioresistance poses a significant challenge to effective radiotherapy.
  • Understanding osteosarcoma radioresistance mechanisms is crucial for improving treatment outcomes.

Purpose of the Study:

  • To investigate the role of LINC00210, miR-342-3p, and GFRA1 in osteosarcoma radioresistance.
  • To elucidate the molecular mechanism underlying osteosarcoma radioresistance.
  • To identify potential therapeutic targets for enhancing radiotherapy in osteosarcoma.

Main Methods:

  • Analysis of LINC00210, miR-342-3p, and GFRA1 expression in osteosarcoma tissues and cells using qRT-PCR.
  • Assessment of cell viability, apoptosis, and radiosensitivity via MTT, flow cytometry, and colony formation assays.
  • Luciferase assays to confirm the interaction between LINC00210, miR-342-3p, and GFRA1.

Main Results:

  • LINC00210 and GFRA1 were upregulated, while miR-342-3p was downregulated in osteosarcoma.
  • LINC00210 directly targeted miR-342-3p, leading to increased GFRA1 expression.
  • LINC00210 knockdown or miR-342-3p overexpression significantly enhanced osteosarcoma cell radiosensitivity.

Conclusions:

  • LINC00210 promotes osteosarcoma radioresistance through the miR-342-3p/GFRA1 pathway.
  • LINC00210 represents a promising therapeutic target for overcoming radioresistance in osteosarcoma.
  • Modulating the LINC00210/miR-342-3p/GFRA1 axis could enhance radiotherapy effectiveness.

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...

MicroRNAs01:22

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...

The Retinoblastoma Gene

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

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...

Loss of Tumor Suppressor Gene Functions

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...
