Insights

microRNAs (miRNAs) are key regulators in head and neck squamous cell carcinoma (HNSCC). Their deregulation impacts cancer risk, progression, and treatment response, offering new therapeutic avenues.

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • Head and neck squamous cell carcinoma (HNSCC) is a significant global health concern.
  • Genetic and epigenetic factors, including microRNA (miRNA) alterations, are crucial in HNSCC development and progression.
  • microRNAs are small noncoding RNAs regulating gene expression, impacting critical cellular processes.

Purpose of the Study:

  • To review the role of microRNA deregulation in head and neck squamous cell carcinoma.
  • To explore the influence of genetic variations in microRNAs and their targets on HNSCC.
  • To highlight the potential of microRNAs as diagnostic markers and therapeutic targets in HNSCC.

Main Methods:

  • Literature review focusing on microRNA expression profiling in HNSCC.
  • Analysis of studies investigating single nucleotide variants in miRNA-related genes and target sites.
  • Synthesis of current knowledge on miRNA involvement in HNSCC risk, development, prognosis, and therapy.

Main Results:

  • microRNA expression is significantly altered (upregulated or downregulated) in HNSCC cells compared to normal cells.
  • Single nucleotide variants in miRNA processing genes and target sites are associated with HNSCC.
  • miRNA deregulation influences HNSCC risk, progression, patient outcomes, and sensitivity to therapy.

Conclusions:

  • microRNA deregulation is a critical factor in head and neck squamous cell carcinoma.
  • microRNAs present promising potential as biomarkers for HNSCC diagnosis and prognosis.
  • Targeting microRNAs may offer novel therapeutic strategies for HNSCC patients, particularly those with limited treatment options.

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...

Abnormal Proliferation02:23

Abnormal Proliferation

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...

Receptor Downregulation in MVBs01:15

Receptor Downregulation in MVBs

Multivesicular bodies (MVBs) are mature endosomes that sort ubiquitinated proteins and then fuse with lysosomes to degrade the sorted proteins. Epidermal growth factor (EGF) and its receptor (EGFR) form a complex that can be internalized through endocytosis, sorted into an MVB, and later degraded.
The EGFR can initiate signaling pathways that  lead to cell proliferation, migration, and differentiation. Overexpression of EGFR  stimulates cells to proliferate. Excessive  EGFR...

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...

Role Of Notch Signalling In Intestinal Stem Cell Renewal01:12

Role Of Notch Signalling In Intestinal Stem Cell Renewal

Notch signaling was first discovered in Drosophila melanogaster, where it is involved in cell lineage differentiation. Notch signaling regulates the maintenance and differentiation of intestinal stem cells or ISCs by controlling the expression of atonal homolog 1 or Atoh1. Atoh1 directs cells to differentiate into secretory cells.
Direct cell-to-cell contact is needed for the activation of Notch signaling. The signal is initiated when a notch ligand binds to a receptor on an adjacent cell, also...
