The NADPH oxidase NOX4 regulates redox and metabolic homeostasis preventing HCC progression

Hepatology, EarlyView., 2022
Loss of NOX4 in HCC tumor cells induces metabolic reprogramming in a Nrf2/MYC‐dependent manner to promote HCC progression. Abstract Background and Aims The NADPH oxidase NOX4 plays a tumor‐suppressor function in HCC. Silencing NOX4 confers higher proliferative and migratory capacity to HCC cells and increases their in vivo tumorigenic potential in ...

Characteristics of bile duct carcinoma with superficial extension in the epithelium. [PDF]

, 2009
BACKGROUND: Longitudinal tumor extension from the main tumor involves intramural or superficial spread along the bile duct, which influences surgical curability. Identifying the range of superficial extension is difficult by preoperative imaging.

AIF1+CSF1R+ MSCs, induced by TNF‐α, act to generate an inflammatory microenvironment and promote hepatocarcinogenesis

Hepatology, EarlyView., 2022
Mesenchymal stem cells subset, educated by TNF‐α, are involved to generate inflammatory microenvironment and promote hepatocarcinogenesis Abstract Background and Aims Increasing evidence suggests that mesenchymal stem cells (MSCs) home to injured local tissues and the tumor microenvironment in the liver.

Intraductal papillary neoplasm of the bile duct

HPB
Intraductal papillary neoplasm of the bile duct (IPNB) was formally adopted in the 2010 WHO classification as a distinct clinical and pathological entity. We herein review the concept, clinical and pathologic features, as well as the prognosis of IPNB.A comprehensive review was conducted using MEDLINE/PubMed, Google Scholar, Cochrane Library, and the ...

Extended right hepatectomy for hilar bile duct carcinoma using the modified liver hanging maneuver [PDF]

, 2012
To achieve complete extended right hepatectomy or trisectionectomy for a bismuth type IV hilar bile duct carcinoma, we propose the application of Belghiti's liver hanging maneuver (LHM) using a small nasogastric tube.

Liver organoids: modelling complexity in homeostasis and disease

FEBS Letters, EarlyView.
Studying liver in vitro has been challenging because simple 2D cell cultures fail to capture liver's cellular and architectural complexity. To bridge this gap, scientists increasingly use organoids, 3D liver models which better mimic liver composition and function. This review examines recent advances in liver organoid complexity and realism, discusses

Attacking the public health crisis of hepatocellular carcinoma at its roots

Hepatology, EarlyView., 2022
Abstract As the third most common cause of cancer‐related death worldwide with significant mortality rates in the United States, hepatocellular carcinoma has strong association with cirrhosis and chronic hepatitis B virus (HBV) with a growing at‐risk population from the rise in chronic liver disease from alcohol use and nonalcoholic fatty liver disease.
