Transcriptomic Analysis of CAD Cell Differentiation

TL;DR

The study used RNA sequencing to analyze how CAD cells differentiate into neuron-like cells, identifying thousands of genes and pathways involved in this process.

Contribution

The study provides a transcriptomic dataset of CAD cell differentiation, revealing neuron-related gene expression changes and pathways.

Findings

Serum-starved CAD cells undergo morphological changes resembling neurons.

RNAseq identified ~1900 transcripts with altered expression during differentiation.

Pathview analysis revealed ~80 KEGG pathways, including 13 neuron-related pathways, that are differentially expressed.

Abstract

CAD cells were derived from Cath.a cells, a mouse central nervous system catecholaminergic cell line. Serum-starved CAD cells undergo morphological changes and resemble isolated neurons when observed by microscopy. We carried out an RNAseq transcriptomic analysis to examine differentiated CAD cells for expression signatures related to neuronal functions, identifying ~1900 transcripts whose expression changed with differentiation. Pathview analysis identified ~80 KEGG pathway gene sets that were differentially expressed, including upregulation of at least 13 neuron-related pathways. This dataset can be explored more deeply, allowing further investigation into expression changes relevant to studying neuronal functions in this easy-to-culture model system.
