RNA-seq

11.1K
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...

The first human genome sequencing project cost $2.7 billion and was declared complete in 2003, after 15 years of international cooperation and collaboration between several research teams and funding agencies. Today, with the advent of next-generation sequencing technologies, the cost and time of sequencing a human genome have dropped over 100 fold.
Next-Generation Sequencing Methods

Sanger Sequencing

DNA sequencing is a fundamental technique that is routinely used in the biological sciences. This method can be applied to a range of questions at different scales - from the sequencing of a cloned DNA fragment or the study of a mutation in a gene up to whole-genome sequencing. However, despite the widespread use of sequencing today, it was not until 1977 that Fredrick Sanger and his collaborators developed the chain-termination method to decode DNA sequences. It relies on the separation of a...

Maxam-Gilbert Sequencing

11.9K
In the same year as the discovery of the Sanger sequencing method, another group of scientists, Allan Maxam and Walter Gilbert, demonstrated their chemical-cleavage method for DNA sequencing. The Maxam-Gilbert method relies on using different chemicals that can cleave the DNA sequence at specific sites, the separation of resulting DNA fragments of variable size using electrophoresis, and deciphering the DNA sequence from the resulting gel bands.

Area of Science:

  • Genomics
  • Computational Biology
  • Epigenetics

Background:

  • N4-methylcytosine (4mC) is a crucial DNA modification influencing gene expression and cellular development.
  • Accurate identification of 4mC sites is vital for understanding its biological roles.

Purpose of the Study:

  • To develop a deep learning model for predicting 4mC and non-4mC sites in the C.elegans genome.
  • To evaluate the performance of the proposed model against existing state-of-the-art predictors.

Main Methods:

  • Utilized a deep learning-based Convolutional Neural Network (CNN) algorithm with a word embedding approach.
  • Employed corpus k-mer and k-fold cross-validation techniques for model training and evaluation.
  • Applied the 4mCNLP-Deep model to the C.elegans genome dataset.

Main Results:

  • The 4mCNLP-Deep model achieved high performance across five evaluation metrics: Accuracy (0.9354), MCC (0.8608), Specificity (0.8996), Sensitivity (0.9563), and AUC (0.9731).
  • The model demonstrated significant improvements over existing methods, with notable increases in AUC (4.89%).
  • An online webserver was developed for easy access by researchers.

Conclusions:

  • The 4mCNLP-Deep model offers a powerful and accurate computational approach for 4mC site prediction.
  • This tool can aid researchers in investigating the functional implications of 4mC modifications in various biological contexts.
