Insights

Non-coding RNAs (ncRNAs), including microRNAs (miRNAs), lncRNAs, and circRNAs, interact with the Wnt/β-catenin pathway. This interaction influences cancer progression, offering potential biomarkers for diagnosis and prognosis.

Area of Science:

  • Molecular Biology
  • Epigenetics
  • Cancer Research

Background:

  • Non-coding RNAs (ncRNAs) regulate gene expression and are implicated in disease pathogenesis, particularly cancer.
  • Abnormal ncRNA expression contributes to cancer progression by affecting cellular processes.
  • The Wnt/β-catenin signaling pathway is a key oncogenic pathway involved in tumor growth, invasion, and therapy resistance.

Purpose of the Study:

  • To explore the intricate interactions between different types of ncRNAs (miRNAs, lncRNAs, circRNAs) and the Wnt/β-catenin signaling pathway in cancer.
  • To elucidate the role of these ncRNA-Wnt interactions in tumorigenesis and cancer progression.
  • To assess the potential of the ncRNA/Wnt/β-catenin axis as a diagnostic and prognostic biomarker in cancer patients.

Main Methods:

  • Review and synthesis of existing literature on ncRNA function and Wnt/β-catenin signaling in cancer.
  • Analysis of molecular mechanisms by which miRNAs, lncRNAs, and circRNAs regulate Wnt/β-catenin activity.
  • Examination of experimental evidence linking ncRNA-Wnt interactions to cancer hallmarks like proliferation, migration, and therapy resistance.

Main Results:

  • miRNAs can suppress Wnt signaling by binding to the 3'-UTR of Wnt mRNA.
  • LncRNAs exhibit diverse regulatory roles, including direct modulation of Wnt and indirect sponging of miRNAs.
  • CircRNAs emerge as potent stimulators of Wnt signaling, promoting tumor progression, often through circRNA/miRNA interactions.

Conclusions:

  • The ncRNA/Wnt/β-catenin axis plays a critical role in regulating cancer cell proliferation, migration, and response to therapy.
  • Dysregulation of this axis is a significant driver of cancer development and progression.
  • Targeting the ncRNA/Wnt/β-catenin pathway or utilizing it as a biomarker holds promise for cancer diagnostics and therapeutics.

Canonical Wnt Signaling Pathway02:54

Canonical Wnt Signaling Pathway

The gene encoding the main signaling molecules of the Wnt signaling pathways (the Wnt proteins) was discovered almost four decades ago by Nüsslein-Volhard and Wieschaus. They identified and originally named the gene "wingless" (wg) after a phenotype discovered during their landmark genetic screen in Drosophila for body pattern defects. At around the same time, another researcher named Harold Varmus found that a murine tumor virus activates the mammalian wg homolog, Int-1, which...

Non-Canonical Wnt Signaling Pathways

Wnt is a zygotic effect gene that is expressed during very early embryonic development. It regulates various processes in animals starting from early development through the adult stage, such as organogenesis in the embryo and maintenance of neuronal and blood stem cells. Wnt proteins can induce a wide variety of intracellular pathways depending upon the specific abilities of different Wnt ligands to form a complex with shared and cognate receptors in the presence of different co-receptors. The...

Catenins01:23

Catenins

Catenins are characterized by multiple binding domains and dynamic structures that allow them to function as linker proteins in cell junction complexes. All catenins, except α-catenin, contain a characteristic protein sequence called the armadillo repeat and are therefore also called armadillo proteins.
Catenins in Cell Junctions
Catenins bind to cell adhesion molecules such as cadherins and link them to different cytoskeletal proteins depending on the type of cell junction. At the...

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

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...

Experimental RNAi02:15

Experimental RNAi

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...
