RNA-seq

RNA-seq

RNA sequencing, or RNA-Seq, is a high-throughput sequencing technology used to study the transcriptome of a cell. Transcriptomics helps to interpret the functional elements of a genome and identify the molecular constituents of an organism. Additionally, it also helps in understanding the development of an organism and the occurrence of diseases.
Before the discovery of RNA-seq, microarray-based methods and Sanger sequencing were used for transcriptome analysis. However, while...

¹³C NMR: Distortionless Enhancement by Polarization Transfer (DEPT)

When proton-coupled carbon-13 spectra are simplified by a broadband proton decoupling technique, structural information about the coupled protons is lost. Distortionless enhancement by polarization transfer (DEPT) is a technique that provides information on the number of hydrogens attached to each carbon in a molecule. While the DEPT experiment utilizes complex pulse sequences, the pulse delay and flip angle are specifically manipulated. The resulting signals have different phases depending on...

Background:

Gene polymorphism arises from single-nucleotide polymorphisms (SNPs), crucial for biogenetics.
Haplotypes, sequences of SNP loci, contain more genetic information than individual SNPs.
Haplotype assembly is vital for gene function understanding, disease diagnosis, and species gene identification.

Purpose of the Study:

To introduce DeepHapNet, a novel deep learning method for accurate haplotype assembly.
To leverage read pair correlations and clustering for improved haplotype reconstruction.

Main Methods:

Utilized Retentive Network (RetNet) for multiscale feature extraction and learning global read relationships.
Employed SpectralNet for read clustering based on learned features.
Constructed haplotypes from identified read clusters.

Main Results:

DeepHapNet demonstrated strong performance in haplotype assembly for both simulated and real datasets.
The method proved effective for diploid and polyploid organisms.
Successfully handled both long and short sequencing reads.

Conclusions:

DeepHapNet offers a robust and versatile solution for haplotype assembly across various organisms and read types.
The approach advances the field of biogenetics by improving the accuracy and efficiency of genetic information analysis.
