Transcriptomics

Track 1: Transcriptomics

Transcriptomics is the field of biology that studies RNA transcripts on a large scale. The transcriptome is the set of RNAs transcribed by the genome from a specific tissue or cell type at a stage of development and/or in a certain physiological condition. RNAs are either coding or non-coding, which means that some RNAs code for proteins, while other types of RNAs do not. Specifically, mRNA is translated into proteins, while non-coding RNAs can be classified as housekeepers or as regulators. Housekeeping RNAs react as catalytic and structural elements. Regulatory RNAs can be short or long and act as regulatory elements during gene expression.

There are many ways to uncover the transcriptional response of the genome in different tissues and physiological or environmental conditions. Expressed sequence tag (EST, SAGE) based method, hybridization based gene microarray or gene array technology and NGS based RNA sequencing (RNA-seq) technology have been developed to quickly scan the transcriptome and obtain differentially expressed genes..
