Fig 7. Model of suppression of histamine synthesis by polyamines during BMMC differentiation.

Fig 7

The regulation of KLF4 synthesis depends on cellular polyamines at the translational level. Upon polyamine depletion, an upregulation of Hdc expression is caused due to the disappearance of KLF4. Higher levels of histamine is synthesized during differentiation.
