Summary
This study identified abnormal circular RNA (circRNA) expression in osteosarcoma, revealing potential core genes involved in its development. These findings offer new insights into osteosarcoma pathogenesis.
Area of Science:
- Oncology
- Molecular Biology
- Genomics
Background:
- Osteosarcoma is a primary bone malignancy with complex genetic underpinnings.
- Circular RNAs (circRNAs) are emerging as critical regulators in various cancers, including osteosarcoma.
- Understanding circRNA expression profiles is crucial for identifying novel therapeutic targets.
Purpose of the Study:
- To investigate the expression profile of circRNAs in osteosarcoma tissues.
- To identify potential core genes involved in osteosarcoma pathogenesis.
- To explore the functional roles of differentially expressed circRNAs.
Main Methods:
- High-throughput sequencing (Illumina HiSeq) to screen differentially expressed circRNAs.
- Bioinformatics analysis to predict potential functions and pathways.
- Real-time PCR to validate the expression of selected circRNAs in a larger patient cohort.
Main Results:
- Identified 259 differentially expressed circRNAs in osteosarcoma tissues (132 up-regulated, 127 down-regulated).
- Confirmed significant differential expression of specific circRNAs (e.g., circ_32279, circ_24831, circ_2137, circ_20403).
- Associated circRNA dysregulation with the 'phosphatidylinositol signalling system' and 'inositol phosphate metabolism' pathways.
Conclusions:
- A distinct circRNA expression profile is associated with osteosarcoma.
- Deregulated circRNAs may play a significant role in osteosarcoma occurrence and development.
- Further research into these circRNAs could uncover novel diagnostic and therapeutic strategies.

16.3K
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...

195.2K
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...

02:24Regulation of Expression Occurs at Multiple Steps
25.8K
Gene expression can be regulated at almost every step from gene to protein. Transcription is the step that is most commonly regulated. This involves the binding of proteins to short regulatory sequences on the DNA. This association can either promote or inhibit the transcription of a gene associated with the respective sequence.
Transcription results in the generation of precursor (pre-mRNA) that consists of both exons and introns, which needs further processing before being translated to a...

5.2K
How does a complex organism such as a human develop from a single cell? It all starts from a single fertilized egg which gives rise to a vast array of cell types, such as nerve cells, muscle cells, and epithelial cells that characterize the adult? Throughout development and adulthood, cellular differentiation leads cells to assume their final morphology and physiology. Differentiation is the process by which unspecialized cells become specialized to carry out distinct functions.

677
Differential leveling is a precise method in surveying used to determine the elevation difference between two points. Its primary goal is to establish accurate vertical measurements to create level surfaces or grade lines critical for designing and constructing infrastructures such as roads, bridges, and buildings.The procedure for differential leveling begins with setting up and leveling the instrument at a point where the benchmark can be seen. The level rod is held on the benchmark (BM), and...

01:25Implicit Differentiation

In classical mechanics, motion is often described through relationships between spatial coordinates and time. A car moving along a straight highway with constant acceleration serves as a simple case where velocity is an explicit function of time. This scenario results in a linear equation, enabling straightforward analysis using basic differentiation techniques.In contrast, a satellite in circular orbit follows a path defined by an implicit function. The position of the satellite is constrained...
