a Searching for experiments in which SFTPA2 is expressed or differentially expressed. b Viewing expression of SFTPA2 in different tissues and across all baseline experiments. SFTPA2 shows consistently high expression in the lung. c Looking for the same gene in the PCAWG study using Expression Atlas. Expression is low in lung cancers (adenocarcinoma and squamous cell) but high in the corresponding adjacent normal tissue samples. Expression in normal lung is also high in GTEx. d Finally, the downregulation of SFTPA2 is confirmed in further differential assay studies of lung cancer presented in Expression Atlas.
