Gene expression data from bleomycin-instilled lung tissue or control (Sham) of C57BL/6 mice (wild-type mice and transgenic mice expressing dominant-negative form of p38a or constitutive active form of MKK6 in type II alveolar epithelial cells).

Idiopathic pulmonary fibrosis (IPF) is a type of pulmonary fibrosis, a disease that results in scarring and stiffness of lung tissue affecting over 5 million people globally, while the underlying disease mechanisms in IPF are largely unknown. As an animal model of IPF, a single intratracheal injection of bleomycin (BLM) is generally employed, in which cell death of type II alveolar epithelial cells (AEC II) is a trigger of pulmonary fibrosis. One of mitogen-activated protein kinases, p38 is well known as an important regulator of inflammatory responses and cell fate such as apoptosis, differentiation and tumorgenesis. Given that mice with different intrinsic activity of p38 in AEC II were subjected to BLM instillation and investigated, candidate genes in the development of pulmonary fibrosis would be screened. Here, we provide gene expression profiling of lung tissues using the RNA sequencing for identifying changes in gene expression. Overall design: We sought to obtain changes associated with the fibrotic response in sham and BLM injected mice with the different genotypes. Lung samples at 8 days after BLM instillation were selected for RNA extraction and sequencing on NextSeq 500 (Illumina) and used three biological replicates for each condition.
