Summary
This study introduces an integrated platform, RING and O-GlycoVis, for analyzing cell-specific O-glycan synthesis pathways. The tool visualizes glycan distribution and reaction paths, aiding in understanding these crucial cell surface structures.
Area of Science:
- Glycobiology
- Computational Biology
- Bioinformatics
Background:
- Mucin-type O-glycans significantly impact glycoprotein structure, stability, and cell surface interactions.
- The synthesis of O-glycans involves numerous enzymes with cell and tissue-specific expression, leading to pathway diversity.
Purpose of the Study:
- To develop an integrated platform for cell and tissue-specific O-glycan pathway analysis.
- To facilitate the visualization and understanding of complex O-glycosylation networks.
Main Methods:
- Developed an integrated platform combining RING (Rule Input Network Generator) and O-GlycoVis.
- RING uses an English-like language to define enzyme specificity and constraints for glycan synthesis.
- O-GlycoVis visualizes glycan distribution, reaction paths, and relative abundance levels.
Main Results:
- Generated O-glycan profiles for MCF7, T47d, human umbilical vascular endothelium, and Chinese Hamster Ovary cells using transcriptional data.
- Compared computational predictions with experimentally observed O-glycans.
- Demonstrated the platform's ability to add or subtract rules for network generation and visualization.
Conclusions:
- The RING and O-GlycoVis platform enables rule-based network generation and visualization of O-glycosylation pathways.
- Facilitates analysis of O-glycan profiles across different cell types, tissues, and species.
- Provides a valuable tool for studying the functional roles of O-glycans in biological processes.

01:25Protein Glycosylation
9.6K
Glycosylation, the most common post-translational modification for proteins, serves diverse functions. Adding sugars to proteins makes the proteins more resistant to proteolytic digestion. Glycosylated proteins can act as markers and receptors to promote cell-cell adhesion. Additionally, they have many essential quality control functions in the cell, such as correct protein folding and facilitating transport of misfolded proteins to the cytosol, which can be degraded.

02:26Protein Networks
4.5K
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.
To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...

01:26Integration by Parts: Indefinite Integrals
165
Integration by parts is a fundamental technique in calculus for evaluating integrals involving the product of two functions. It is particularly useful when direct integration is not feasible. The method is based on the product rule for differentiation, which states that the derivative of a product equals the derivative of the first function times the second, plus the first function times the derivative of the second. By integrating this identity and rearranging terms, the integration by parts...

01:23Integration by Parts: Definite Integrals

Definite integrals involving the product of two functions over a fixed interval can be evaluated using integration by parts. This method rewrites the integral as the difference of a product evaluated at the endpoints and a remaining definite integral that is often simpler to compute.A representative example is the definite integral of the inverse tangent function. Since there is no direct integration formula for arctan x, the integrand is rewritten as a product of arctan x and the...
