lncRNA - Long Non-coding RNAs

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...

Protein Networks

Protein Networks

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,...

Non-LTR Retrotransposons

Non-LTR Retrotransposons

As the name suggests, non-LTR retrotransposons lack the long terminal repeats characteristic of the LTR retrotransposons. Additionally, both LTR and non-LTR retrotransposons use distinct mechanisms of mobilization. Non-LTR retrotransposons are further divided into two classes - Long interspersed nuclear elements (LINEs) and short interspersed nuclear elements (SINEs), both of which occur abundantly in most mammals, including humans. Some of the active non-LTR retrotransposons in humans are L1...

Background:

Genetic and environmental factors significantly influence disease development.
Long non-coding RNAs (lncRNAs) are key regulators of biological processes.
Accurate prediction of lncRNA-environmental factor (EF) associations is vital for disease research.

Purpose of the Study:

To develop an improved method for predicting associations between lncRNAs and EFs.
To address limitations in existing methods that neglect network topology and semantic path meanings.

Main Methods:

Proposed the Gradient Boosting Decision Tree for lncRNA-EF association prediction (GBDTL2E).
Integrated structural information from heterogeneous biological networks.
Combined Hetesim and diffusion features using multi-feature fusion.
Employed the Gradient Boosting Decision Tree (GBDT) machine learning algorithm.

Main Results:

The GBDTL2E method demonstrated high predictive performance.
The approach effectively leverages topological information in heterogeneous networks.
Multi-feature fusion enhanced the accuracy of lncRNA-EF association predictions.

Conclusions:

GBDTL2E offers a powerful new approach for predicting lncRNA-EF associations.
The method's integration of network topology and feature fusion advances the field.
This work has significant implications for understanding gene-environment interactions in disease.
