"WebThe TGF-β-smad4 axis regulates the expression of the Gli1 factor, but our results revealed that smad4 did not affect the expression of Gli1 factor induced by TGF-β in VICs, while smad 2/3 factor was the regulator of Gli1 expression [36, 37]. This is another interesting point that needs to be further explored. Supplementary Material " - Phenotypic expression definition

An example of a phenotypic trait is a specific hair color or eye colour. Underlying genes, which make up the genotype, determine the hair color, but the hair color observed is the phenotype. The phenotype is dependent on the genetic make-up of the organism, and also influenced by the environmental conditions to which the organism is subject…
