Circular RNA Expression Profile in Laryngeal Squamous Cell Carcinoma Revealed by Microarray
Summary
Circular RNAs (circRNAs) are dysregulated in laryngeal squamous cell carcinoma (LSCC). Two specific circRNAs, hsa_circ_0044520 and hsa_circ_0044529, were found to be upregulated and involved in collagen synthesis, offering new insights into LSCC tumorigenesis.
Area of Science:
- Molecular Biology
- Genomics
- Cancer Research
Background:
- Circular RNAs (circRNAs) regulate gene expression and are implicated in various cancers.
- The specific roles of circRNAs in laryngeal squamous cell carcinoma (LSCC) are not well understood.
Purpose of the Study:
- To investigate global circRNA expression patterns in LSCC.
- To identify differentially expressed circRNAs and their potential roles in LSCC pathogenesis.
Main Methods:
- Microarray analysis of circRNA expression in LSCC and normal tissues.
- Quantitative real-time PCR for candidate circRNAs and microRNAs (miRNAs).
- Bioinformatics analysis for pathway enrichment and circRNA-miRNA interactions.
Main Results:
- Identified 506 differentially expressed circRNAs in LSCC.
- Confirmed significant upregulation of hsa_circ_0044520 and hsa_circ_0044529 in LSCC tissues.
- Associated these circRNAs with collagen synthesis and predicted interactions with hsa-miR-4726-5p and hsa-miR-4640-5p.
Conclusions:
- hsa_circ_0044520 and hsa_circ_0044529 play regulatory roles in LSCC tumorigenesis.
- These circRNAs may function as competing endogenous RNAs (ceRNAs) by sponging specific miRNAs.
- Findings provide novel insights into the molecular mechanisms underlying LSCC development.

01:58Cell Specific Gene Expression
16.6K
Multicellular organisms contain a variety of structurally and functionally distinct cell types, but the DNA in all the cells originated from the same parent cells. The differences in the cells can be attributed to the differential gene expression. Liver cells, whose functions include detoxification of blood, production of bile to metabolize fats, and synthesis of proteins essential for metabolism, must express a specific set of genes to perform their functions. Gene expression also varies with...

02:35Chromatin Position Affects Gene Expression
24.9K
Chromatin is the massive complex of DNA and proteins packaged inside the nucleus. The complexity of chromatin folding and how it is packaged inside the nucleus greatly influences access to genetic information. Generally, the nucleus' periphery is considered transcriptionally repressive, while the cell's interior is considered a transcriptionally active area.

196.8K
Overview
Gene expression is the process in which DNA directs the synthesis of functional products, that is, proteins. Cells can regulate gene expression at various stages. It allows organisms to generate different cell types and enables cells to adapt to internal and external factors.
Genetic Information Flows from DNA to RNA to Protein
A gene is a stretch of DNA that serves as the blueprint for functional RNAs and proteins. Since DNA is made up of nucleotides and proteins consist of amino...

01:10Deformation in a Circular Shaft
924
One of the distinctive characteristics of circular shafts is their ability to maintain their cross-sectional integrity under torsion. In other words, each cross-section continues to exist as a flat, unaltered entity, simply rotating like a solid, rigid slab. To understand the distribution of shearing stress within such a shaft, consider a cylindrical section inside this circular shaft. This section has a length of L and a radius of R, with one end fixed. The radius of the cylindrical section is...

21.2K
Microarrays are high-throughput and relatively inexpensive assays that can be automated to analyze large quantities of data at a time. They are used in genome-wide studies to compare gene or protein expression under two varied conditions, such as healthy and diseased states. Microarrays consist of glass or silica slides on which probe molecules are covalently attached through surface functionalization. Most commonly, the slides are prepared through the chemisorption of silanes to silica...

01:23RNA Interference
28.1K
RNA interference (RNAi) is a process in which a small non-coding RNA molecule blocks the post-transcriptional expression of a gene by binding to its messenger RNA (mRNA) and preventing the protein from being translated.
This process occurs naturally in cells, often through the activity of genomically-encoded microRNAs. Researchers can take advantage of this mechanism by introducing synthetic RNAs to deactivate specific genes for research or therapeutic purposes. For example, RNAi could be used...
