Figure 8. A hypothetical model explaining disregulation of maspin in tumor progression.

Figure 8

(A) Benign tumor or better differentiated cancer with better prognosis is associated with nuclear maspin. Nuclear maspin has a stronger affinity towards HDAC1 as compared to hypothetical HDAC1-associated nuclear factor X. (B) High grade carcinoma exhibiting a less differentiated phenotype and worse prognosis is associated with cytosolic maspin or loss of maspin. In cancer, hypothetical HDAC1- associated nuclear factor X is X′ and it has a stronger affinity towards HDAC1 as compared to maspin. (C) Therapeutic potential of bioengineered maspin mutant or its derivative in treating advanced disease. Maspin mutant restores maspin nuclear localization and HDAC1 inhibition in advanced disease.
