Grainyhead-like transcription factor 2 (GRHL2)

Grainyhead-like transcription factor 2 (GRHL2) is a highly conserved transcription factor vital for epithelial morphogenesis, differentiation, and maintenance of epithelial integrity[1][3][5][6]. It acts as a master regulator of epithelial phenotype by directly activating genes encoding adhesion molecules (such as E-cadherin and claudins) and is essential for proper neural tube closure, epithelial barrier formation in multiple organs, and regulation of gene expression at the chromatin level[5][6]. GRHL2 suppresses the epithelial–mesenchymal transition (EMT), thereby preventing processes involved in cancer metastasis and tumor progression; however, GRHL2 can also function as a tumor enhancer in certain contexts. Loss or dysregulation of GRHL2 is associated with neural tube defects, hearing loss, epithelial cancers, and impaired wound healing[3][5][6]. GRHL2 does not have known direct pharmacological inhibitors or therapies but remains an active area of research for cancer biology and developmental disorders.

Not applicable; no drugs directly target this factor. Indirect targeting (e.g., modulation of downstream pathways such as EMT, chromatin modification, or via hormone receptor signaling) has been discussed in research[3][5].
