Summary

This summary is machine-generated.

MicroRNA miR-193b-3p inhibits esophageal cancer (ESCA) progression by targeting RSF1. This miR-193b-3p/RSF1 axis is a critical regulator of ESCA, offering potential therapeutic targets.

Area Of Science

  • Molecular oncology
  • Cancer biology
  • Gene regulation

Background

  • Esophageal cancer (ESCA) is a leading cause of cancer mortality globally.
  • The molecular mechanisms driving ESCA initiation and progression are not fully elucidated.
  • MicroRNAs (miRNAs) are recognized as key regulators in various cancers.

Purpose Of The Study

  • To identify novel molecular regulators of esophageal cancer progression.
  • To investigate the role of microRNA miR-193b-3p and its target gene RSF1 in ESCA.

Main Methods

  • Analysis of TCGA_ESCA dataset and RT-qPCR to assess RSF1 and miR-193b-3p expression.
  • Dual-luciferase reporter assays and miRNA mimic/inhibitor transfections to confirm RSF1 as a direct target of miR-193b-3p.
  • In vitro cell proliferation, migration, and invasion assays, and in vivo xenograft mouse models.

Main Results

  • RSF1 expression is significantly elevated in ESCA and inversely correlated with miR-193b-3p levels.
  • miR-193b-3p directly targets and downregulates RSF1 in ESCA cells.
  • Overexpression of miR-193b-3p suppressed ESCA cell proliferation, migration, and invasion, effects partially reversed by RSF1.
  • AgomiR-193b-3p administration inhibited tumor growth in ESCA xenograft models.

Conclusions

  • The miR-193b-3p/RSF1 axis plays a critical role in the progression of esophageal cancer.
  • miR-193b-3p acts as a tumor suppressor in ESCA by targeting RSF1.
  • This axis represents a potential therapeutic target for esophageal cancer treatment.

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...

Abnormal Proliferation 02:23

4.6K

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...

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...
