Abstract

Insights

MicroRNA-330-3p (miR-330-3p) suppresses glioma cell growth and migration. This study found miR-330-3p targets and downregulates CELF1, offering a potential therapeutic target for glioma.

Area of Science:

  • Neuro-oncology
  • Molecular biology
  • Cancer research

Background:

  • Glioma is a prevalent central nervous system neoplasm.
  • MicroRNAs (miRNAs) are key regulators in cancer development.
  • The specific role of miR-330-3p in glioma was previously undetermined.

Purpose of the Study:

  • To investigate the function of miR-330-3p in glioma cell proliferation and migration.
  • To elucidate the molecular mechanism of miR-330-3p in glioma.

Main Methods:

  • Quantitative real-time PCR (qRT-PCR) and Western blot to assess expression levels.
  • Dual-luciferase reporter assay to confirm direct targeting.
  • MTT, colony formation, and wound healing assays to evaluate cellular effects.

Main Results:

  • miR-330-3p expression was significantly lower in glioma tissues and cells compared to normal tissues.
  • CELF1 expression was inversely correlated with miR-330-3p levels.
  • miR-330-3p directly targets CELF1 and suppresses glioma cell proliferation and migration.

Conclusions:

  • miR-330-3p acts as a tumor suppressor in glioma.
  • Inhibition of glioma cell propagation and migration by miR-330-3p is mediated through CELF1 repression.

Abnormal Proliferation02:23

Abnormal Proliferation

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 Retinoblastoma Gene01:20

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,...

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...

Mitogens and the Cell Cycle02:38

Mitogens and the Cell Cycle

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...

Negative Regulator Molecules01:23

Negative Regulator Molecules

Positive regulators allow a cell to advance through cell cycle checkpoints. Negative regulators have an equally important role as they terminate a cell’s progression through the cell cycle—or pause it—until the cell meets specific criteria.
