Abstract

Insights

Long non-coding RNAs (lncRNAs) and microRNAs (miRNAs) interact with messenger RNAs (mRNAs) to regulate endometrial cancer (EC). Dysregulated lncRNA-miRNA-mRNA networks offer new diagnostic and therapeutic targets for EC.

Area of Science:

  • Molecular Biology
  • Genetics
  • Oncology

Background:

  • Endometrial cancer (EC) is a common gynecological malignancy with unclear etiology and prognostic factors.
  • Non-coding RNAs, including long non-coding RNAs (lncRNAs) and microRNAs (miRNAs), play crucial roles in tumorigenesis and disease progression.
  • Dysregulation of lncRNA-miRNA-mRNA interactions is increasingly recognized in the pathophysiology of EC.

Purpose of the Study:

  • To review the role of lncRNA-miRNA-mRNA axes in endometrial cancer.
  • To elucidate the molecular mechanisms underlying endometrial carcinogenesis.
  • To identify potential diagnostic biomarkers and therapeutic targets for EC.

Main Methods:

  • A comprehensive literature review was performed.
  • Focused on studies investigating lncRNA-miRNA-mRNA interactions in EC.
  • Synthesized findings on the regulatory roles of these interactions.

Main Results:

  • lncRNAs function as molecular sponges, sequestering tumor suppressor miRNAs.
  • This sequestration disrupts miRNA function, leading to dysregulation of target mRNAs.
  • These molecular events contribute to the regulation and progression of EC.

Conclusions:

  • lncRNA-miRNA-mRNA networks are integral to endometrial carcinogenesis.
  • Understanding these pathways enhances conceptualization of EC's molecular basis.
  • These interactions present promising avenues for novel diagnostic biomarkers and therapeutic interventions in EC.

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...

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...

Metastasis02:30

Metastasis

Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

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...
