Improving Translational Accuracy

Improving Translational Accuracy

Base complementarity between the three base pairs of mRNA codon and the tRNA anticodon is not a failsafe mechanism. Inaccuracies can range from a single mismatch to no correct base pairing at all. The free energy difference between the correct and nearly correct base pairs can be as small as 3 kcal/ mol. With complementarity being the only proofreading step, the estimated error frequency would be one wrong amino acid in every 100 amino acids incorporated. However, error frequencies observed in...

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...

Ligand Binding and Linkage

Ligand Binding and Linkage

Allosteric proteins have more than one ligand binding site; the binding of a ligand to any of these sites influences the binding of ligands to the other sites. When a protein is allosteric, its binding sites are called coupled or linked. In the case of enzymes, the site that binds to the substrate is known as the active site and the other site is known as the regulatory site. When a ligand binds to the regulatory site, this leads to conformational changes in the protein that can influence...

Background:

Bio-entity coreference resolution is vital for understanding biomedical texts and constructing bio-networks.
Existing deep learning models struggle with integrating complex domain-specific information and context.
Previous methods often introduce noise due to insufficient context and domain knowledge integration.

Purpose of the Study:

To improve bio-entity coreference resolution by effectively leveraging external knowledge bases.
To develop a more flexible and accurate model for biomedical text analysis.

Main Methods:

Introduction of a knowledge-enhanced Long Short Term Memory (LSTM) network.
Development of a knowledge attention module for effective context-based knowledge extraction.
Fine-grained integration of external knowledge into the LSTM architecture.

Main Results:

Achieved state-of-the-art performance on the BioNLP and CRAFT datasets.
Demonstrated significant performance gains: 7.5 F1 on BioNLP and 10.6 F1 on CRAFT.
Showcased superior performance in cross-sentence coreference resolution.

Conclusions:

The proposed knowledge-enhanced LSTM model effectively addresses limitations in current bio-entity coreference resolution.
Leveraging external knowledge bases through fine-grained integration and attention mechanisms enhances model accuracy.
The method offers a promising advancement for biomedical text mining and knowledge discovery.
