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...

Ribosome Profiling

Ribosome Profiling

Ribosome profiling or ribo-sequencing is a deep sequencing technique that produces a snapshot of active translation in a cell. It selectively sequences the mRNAs protected by ribosomes to get an insight into a cell’s translation landscape at any given point in time.
Applications of ribosome profiling
Ribosome profiling has many applications, including in vivo monitoring of translation inside a particular organ or tissue type and quantifying new protein synthesis levels.
The technique...

Area of Science:

Computational Biology
Genomics
Bioinformatics

Background:

High-dimensional data from new technologies presents challenges and opportunities for cancer research.
Complex diseases like cancer arise from patient-specific network dysfunctions, not single component failures.
Understanding individual molecular mechanisms requires patient-specific biological networks.

Purpose of the Study:

To develop a method for constructing patient-specific networks to analyze cancer's molecular mechanisms.
To identify patient-specific regulatory modules and driver genes for personalized drug design.
To characterize patient-specific disease subtypes and gene interactions.

Main Methods:

Constructing patient-specific networks using sample-specific network theory.
Integrating cancer-specific differentially expressed genes and elite genes.
Applying the methodology in R language.

Main Results:

Successfully identified regulatory modules, driver genes, and personalized disease networks.
Provided insights into gene associations and patient-specific disease subtypes.
Demonstrated effectiveness over existing methods for three cancer types (STAD, PAAD, LUAD) through literature, enrichment, and survival analysis.

Conclusions:

The developed method effectively detects patient-specific differential modules and gene interactions.
This approach is beneficial for personalized therapeutics and drug design in cancer.
The R implementation is publicly available for broader application.
