Insights

Long non-coding RNAs (lncRNAs) show potential for diagnosing and treating endometrial cancer (EC). Dysregulated lncRNAs impact EC progression and patient survival, offering new therapeutic targets.

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • Long non-coding RNAs (lncRNAs) are increasingly recognized for their roles in cancer development and progression.
  • Dysregulation of lncRNAs is a hallmark of endometrial cancer (EC), correlating with tumor grade, stage, invasion, metastasis, and patient survival.

Purpose of the Study:

  • To provide a comprehensive overview of lncRNA expression, function, and prognostic value in endometrial cancer.
  • To explore the influence of lncRNAs on key signaling pathways involved in EC metastasis.
  • To discuss the potential of lncRNAs as diagnostic biomarkers and therapeutic targets for EC.

Main Methods:

  • Review of recent literature on lncRNAs in endometrial cancer.
  • Analysis of lncRNA expression patterns and their correlation with clinical parameters.
  • Investigation of lncRNA involvement in major oncogenic and tumor-suppressive signaling pathways.

Main Results:

  • Specific tumor-suppressive (e.g., GAS5, MEG3) and oncogenic (e.g., CCAT2, MALAT1) lncRNAs have been identified in EC.
  • lncRNAs modulate critical signaling pathways including PTEN/PI3K/AKT/mTOR, RAS/RAF/MEK/ERK, WNT/β-catenin, p53, VEGF-A, and JAK/STAT3.
  • lncRNA signatures are emerging for EC subtype classification.

Conclusions:

  • lncRNAs play significant roles in EC cell biology, tumor microenvironment, and metastasis.
  • lncRNAs hold promise as valuable biomarkers for EC diagnosis and as potential therapeutic targets for treatment.

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...

The Tumor Microenvironment02:17

The Tumor Microenvironment

Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...

Cancer Stem Cells and Tumor Maintenance02:40

Cancer Stem Cells and Tumor Maintenance

Early diagnosis and treatment can often cure cancer. However, even with treatment, residual cells called cancer stem cells (CSC) might remain, often causing tumor recurrence. These cancer stem cells possess the potential for self-renewal and multi-lineage differentiation and are often responsible for the therapeutic resistance displayed in most cancers.
Cancer stem cells are thought to originate from tissue-specific normal stem cells or progenitor cells. The normal stem cells usually reside in...

Cis-regulatory Sequences02:02

Cis-regulatory Sequences

Cis-regulatory sequences are short fragments of non-coding DNA that are present on the same chromosomes as the genes that they regulate. These fragments serve as binding sites for transcriptional regulators, proteins that are responsible for controlling gene transcription and differential gene expression across cell types in eukaryotes. Cis-regulatory sequences can be close to the gene of interest or thousands of bases away in the DNA sequence; however, those sequences that are further away are...
