Insights

Non-coding RNAs (ncRNAs) significantly impact cancer progression by regulating epithelial-mesenchymal transition (EMT). These ncRNAs influence metastasis, drug sensitivity, and offer potential for cancer diagnosis and prognosis.

Area of Science:

  • Molecular Biology
  • Oncology
  • Genetics

Background:

  • Non-coding RNAs (ncRNAs) are crucial regulators of cellular processes like growth and differentiation.
  • Aberrant ncRNA expression is linked to various diseases, particularly cancer.
  • Epithelial-mesenchymal transition (EMT) is a key mechanism in cancer invasion and metastasis.

Purpose of the Study:

  • To investigate the role of ncRNAs in regulating EMT.
  • To understand the impact of ncRNA-EMT interactions on cancer progression, metastasis, and drug sensitivity.
  • To explore the potential of ncRNAs in cancer diagnosis and prognosis.

Main Methods:

  • Review and analysis of existing literature on ncRNAs and EMT in cancer.
  • Examination of how different types of ncRNAs (miRNAs, lncRNAs, circRNAs) modulate EMT pathways.
  • Investigation of exosome-mediated transfer of ncRNAs and their effect on cancer.

Main Results:

  • MicroRNAs (miRNAs) regulate EMT via pathways like PI3K/Akt and PTEN, affecting metastasis and drug sensitivity.
  • Long non-coding RNAs (lncRNAs) and circular RNAs (circRNAs) target key EMT regulators (ZEB1/2, Twist, Snail) and influence therapy response.
  • ncRNAs, including those transferred via exosomes, play a significant role in modulating EMT, impacting cancer metastasis and drug sensitivity.

Conclusions:

  • ncRNAs are critical regulators of EMT in cancer, influencing key processes like metastasis and drug resistance.
  • The interplay between different ncRNAs (miRNAs, lncRNAs, circRNAs) and EMT pathways offers therapeutic targets.
  • ncRNAs hold promise as diagnostic and prognostic biomarkers for cancer, particularly in relation to EMT.

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...

Regulation of Expression at Multiple Steps01:23

Regulation of Expression at Multiple Steps

The gene expression in cells is regulated at different stages: (i) transcription, (ii) RNA processing, (iii) RNA localization, and (iv) translation. Transcriptional regulation is mediated by regulatory proteins such as transcription factors, activators, or repressors—these control gene expression by initiating or inhibiting the transcription of genes. Once a precursor or pre-mRNA is produced, it undergoes post-transcriptional modification, including 5' capping, splicing, and the...

Types of RNA01:20

Types of RNA

Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in regulating gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.

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...

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...

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...
