Is it rational to identify differentially expressed genes from tissues (in silico) and examine gene expression on the associated cell lines (wet lab)?

I am going to evaluate the gene expression levels in the MKN45 cell line (gastric cancer). Before that, I want to identify critical differentially expressed genes obtained from tissues available...

Is rationality normative? Can rationality be naturalized? Is rationality depended on normative conditions, or is it independent of normativity?

Rationality is itself an elusive term. There are debates on the definition and criteria of rationality. The primary assumption of the naturalized and non-naturalized rationality on normative...
