Sonic hedgehog expression in steatohepatitic hepatocellular carcinoma and its clinicopathological significance.

Hedgehog (Hh) signaling pathway dysregulation is involved in the pathogenesis of metabolic dysfunction-associated steatohepatitis, and the sonic Hh (SHh) protein, a pivotal molecule in the Hh pathway, is expressed in ballooned hepatocytes. The present study aimed to investigate the clinicopathological significance of SHh expression in steatohepatitic hepatocellular carcinoma (SH-HCC). Reverse transcription-quantitative polymerase chain reaction and immunohistochemistry were performed to examine gene and SHh protein expression in SH-HCC.

Clinicopathological characteristics and molecular analysis of lymphocyte-rich hepatocellular carcinoma.

Lymphocyte-rich hepatocellular carcinoma (LR-HCC), a newly proposed subtype of HCC, is characterized with abundant lymphocyte infiltration in the tumor. LR-HCC has a relatively good prognosis and is quite rare (<1% of all HCC). We examined LR-HCC clinicopathological and molecular characteristics by analyzing 451 surgically resected HCC cases without any prior treatment history at our hospital between 2012 and 2021.

Prognostic impact of vessels encapsulating tumor clusters and macrotrabecular patterns in hepatocellular carcinoma.

Background: Hepatocellular carcinoma (HCC) shows a high mortality rate. A macrotrabecular (MT) pattern and vessels encapsulating tumor clusters (VETC) pattern have been reported as aggressive histological patterns in HCC. However, their cut-off values have been contentious.

Predictive and Prognostic Value of SUOX Expression in Pancreatic Ductal Adenocarcinoma.

Background/aim: Sulphite oxidase (SUOX) is a metalloenzyme that catalyses ATP synthesis via oxidative phosphorylation in the mitochondria. Although SUOX has been reported to affect the invasiveness and differentiation of cancer cells, its clinicopathological significance in pancreatic adenocarcinoma (PDAC) remains unclear. In this study, we investigated the utility of SUOX expression as a prognostic factor in PDAC.

SUOX and GLUT1 are biomarkers for the prognosis in large duct type intrahepatic cholangiocarcinoma.

Intrahepatic cholangiocarcinoma (iCCA) is the second most common hepatic malignant disease and has a poor prognosis, but few biomarkers have been found. SUOX is an important factor in energy metabolism and a poor prognostic factor in other malignancies. In this study, we aimed to clarify the relationship between SUOX and GLUT expression in large duct type iCCA and the mechanism of mitochondrial energy metabolism in iCCA.

Utility of sonic hedgehog and keratin 8/18 immunohistochemistry for detecting ballooned hepatocytes.

Aims: Ballooned hepatocytes represent liver cell degeneration and are histological hallmarks in the diagnosis of non-alcoholic steatohepatitis, a severe form of non-alcoholic fatty liver disease. However, the identification of ballooned hepatocytes is often difficult, especially in the clinical setting of patients with other chronic liver diseases. In this study, we investigated the utility of immunostaining for positive sonic hedgehog (SHh) protein and negative Keratin 8/18 (K8/18) expression on ballooned hepatocytes.
