ORGANISM

LITERATURE
downregulated specifically in tumours
long-term exposure (24 h) of INS 832/13 cells or rat islets to high glucose (30 mM) increases the expression of the enzyme. Such increases in enzyme expression are also seen in islets derived from the Zucker diabetic fatty rat compared with islets from the lean control animals
-
PHP14 expression is upregulated in fibrotic liver and mainly in hepatic stellate cells. TGF-beta1 can induce PHP14 expression in hepatic stellate cells accompanied with the activation of hepatic stellate cells
