The authors have previously described the presence of gammaglutamyl transferase and alkaline phosphatase in the saliva of healthy individuals and of patients with hepatobiliary and pancreatic diseases. The authors show in this work the values of said enzymes in the blood serum and saliva of 23 cases
This study aimed to investigate the role of src-homology protein tyrosine phosphatase-1 (SHP-1)-signal transducer and activator of transcription 3 (STAT3) pathway in liver fibrogenesis and the anti-fibrotic effect of SHP-1 agonist. The antifibrotic activity of SC-43, a sorafenib derivative with an
BACKGROUND
Over-activation of TGFβ signaling pathway and uncontrolled cell proliferation of hepatic stellate cells (HSCs) play pivotal roles in liver fibrogenesis, while the protein serine/threonine phosphatase PP2Cα was reported to negatively regulate TGFβ signaling pathway and cell cycle. Our
Hyperphosphatasemia due to increased intestinal type serum alkaline phosphatase was noted in a 48-year-old male who had asymptomatic liver cirrhosis. The alkaline phosphatase activity in the serum was 828 U/l (our reference range in adults: 57-194 U/l), 94% of which was of the intestinal type as
Phosphatase and tensin homologue deleted on chromosome 10 (PTEN) has been reported to play a role in the suppression of activated hepatic stellate cells (HSCs). Moreover, it has been demonstrated that hypermethylation of the PTEN promoter is responsible for the loss of PTEN expression during HSC
The study of a group of 114 hepatic patients allowed us to demonstrate the presence of an isophosphatase band, called ALP4, which can be of value as an index of evolutive cirrhosis. A certain correlation between the presence of this alkaline phosphatase isoenzyme in serum and histological evidence
OBJECTIVE
To evaluate the effects of phosphatase and tension homologue deleted on chromosome ten (PTEN) gene on collagen metabolism in hepatic fibrosis and the underlying mechanisms.
METHODS
Rat primary hepatic stellate cells (HSCs) and human LX-2 cells were transfected with adenovirus containing
