Multiple molecular biology studies demonstrate that the overexpression of single genes consistently drives broad downstream transcriptomic and phenotypic shifts in cellular response pathways.
The retrieved literature contains several experimental studies showing that overexpressing specific genes (e.g., MsCKX5, CTGF, A20, PobZIP8) leads to significant downstream alterations in cellular response pathways, transcriptional profiles, and phenotypes. There are no papers refuting this claim.
