Epigallocatechin-3-gallate inhibits osteopontin expression and prevents experimentally induced hepatic fibrosis.

Biomed Pharmacother 2022 May 17;151:113111. Epub 2022 May 17.

Department of Hepatology, Kanazawa Medical University, Uchinada, Ishikawa 920-0293, Japan; Center for Regenerative Medicine, Kanazawa Medical University Hospital, Uchinada, Ishikawa 920-0293, Japan.

Osteopontin (OPN) is a matricellular cytokine and a stress-induced profibrogenic molecule that promotes activation of stellate cells during the pathogenesis of hepatic fibrosis. We studied the protective effects of epigallocatechin-3-gallate (EGCG) to suppress oxidative stress, inhibit OPN expression, and prevent experimentally induced hepatic fibrosis. Liver injury was induced with intraperitoneal injections of N-nitrosodimethylamine (NDMA) in a dose of 1 mg/100 g body weight on 3 consecutive days of a week for 28 days. Read More

Low-dose X-ray irradiation combined with FAK inhibitors improves the immune microenvironment and confers sensitivity to radiotherapy in pancreatic cancer.

Biomed Pharmacother 2022 May 17;151:113114. Epub 2022 May 17.

Department of Radiation Oncology, Shanghai General Hospital, Shanghai Jiao Tong University School of Medicine, Shanghai 201620, China. Electronic address:

Radiation therapy offers limited clinical benefits for patients with pancreatic cancer, partly as a result of the predominantly immunosuppressive microenvironment characteristic of this specific type of cancer. A large number of abnormal blood vessels and high-density fibrous matrices in pancreatic cancer will lead to hypoxia within tumor tissue and hinder immune cell infiltration. We used low-dose X-ray irradiation, also known as low-dose radiation therapy (LDRT), to normalize the blood vessels in pancreatic cancer, while simultaneously administering an inhibitor of focal adhesion kinase (FAK) to reduce pancreatic cancer fibrosis.

Collagen 3D matrices as a model for the study of cell behavior in pulmonary fibrosis.

Exp Lung Res 2022 May 20:1-11. Epub 2022 May 20.

National Consortium of Research in Respiratory Diseases, CIBERES Instituto de Salud Carlos III, Madrid, Spain.

Idiopathic pulmonary fibrosis (IPF) is a complex progressive chronic lung disease where epithelial to mesenchymal interaction, extracellular matrix (ECM) contact, and pro-fibrotic cytokines dynamics take part in the development of the disease. The study of IPF in the widespread two-dimensional (2 D) culture fails to explain the interaction of cells with the changing environment that occurs in fibrotic lung tissue. A three-dimensional (3 D) co-culture model might shed light on the pathogenesis of IPF by mimicking the fibrotic environment. Read More

Adipose Tissue in Lymphedema: A Central Feature of Pathology and Target for Pharmacologic Therapy.

Lymphat Res Biol 2022 May 20. Epub 2022 May 20.

Division of Plastic and Reconstructive Surgery, Department of Surgery, Washington University School of Medicine, St. Louis, Missouri, USA.

Lymphedema is a chronic condition of impaired lymphatic flow that results in limb swelling and debilitation. The pathophysiology of lymphedema is characterized by lymphatic stasis that triggers inflammation, fibrosis, and adipose tissue deposition in the extremities. Most often, this condition occurs in cancer survivors in the years after treatment with combinations of surgery, radiation, or chemotherapy, with the major risk factor being lymph node dissection.

Effect of airway clearance therapies on mucociliary clearance in adults with cystic fibrosis: A randomized controlled trial.

PLoS One 2022 20;17(5):e0268622. Epub 2022 May 20.

Department of Medicine, University of North Carolina (UNC), Chapel Hill, North Carolina, United States of America.

Background: Cystic fibrosis (CF) is an inherited disorder causing impaired mucociliary clearance within the respiratory tract, and is associated with bronchiectasis, chronic respiratory infections, and early death. Airway clearance therapies have long been a cornerstone of management of individuals with CF, although evidence supporting their use is lacking. We designed a randomized controlled trial to quantitatively compare the effects of different forms of airway clearance on mucociliary clearance. Read More

Eur Radiol 2022 May 20. Epub 2022 May 20.

Departments of Digestive Surgery Nihon University School of Medicine, Tokyo, Japan.

Objectives: To compare the predictive ability of liver fibrosis (LF) by CT-volumetry (CTV) for liver and spleen and extracellular volume fraction (ECV) for liver in patients undergoing liver resection.

Dysregulation of the Scribble/YAP/β-catenin axis sustains the fibroinflammatory response in a PKHD1 mouse model of congenital hepatic fibrosis.

FASEB J 2022 Jun;36(6):e22364

Department of Molecular Medicine (DMM), University of Padova, Padova, Italy.

Congenital hepatic fibrosis (CHF), a genetic cholangiopathy characterized by fibropolycystic changes in the biliary tree, is caused by mutations in the PKHD1 gene, leading to defective fibrocystin (FPC), changes in planar cell polarity (PCP) and increased β-catenin-dependent chemokine secretion. In this study, we aimed at understanding the role of Scribble (a protein involved in PCP), Yes-associated protein (YAP), and β-catenin in the regulation of the fibroinflammatory phenotype of FPC-defective cholangiocytes. Immunohistochemistry showed that compared with wild type (WT) mice, in FPC-defective (Pkhd1 ) mice nuclear expression of YAP/TAZ in cystic cholangiocytes, significantly increased and correlated with connective tissue growth factor (CTGF) expression and pericystic fibrosis, while Scribble expression on biliary cyst cells was markedly decreased.

An update on the functional roles of long non‑coding RNAs in ischemic injury (Review).

Int J Mol Med 2022 Jul 20;50(1). Epub 2022 May 20.

Affiliated Eye Hospital of Nanchang University, Jiangxi Research Institute of Ophthalmology and Visual Science, Jiangxi Clinical Research Center for Ophthalmic Disease, Nanchang, Jiangxi 330006, P.R. China.

Ischemic injuries result from ischemia and hypoxia in cells. Tissues and organs receive an insufficient supply of nutrients and accumulate metabolic waste, which leads to the development of inflammation, fibrosis and a series of other issues. Ischemic injuries in the brain, heart, kidneys, lungs and other organs can cause severe adverse effects. Read More

Towards a more precise classification of esophageal motility disorders in patients with systemic sclerosis.

Neurogastroenterol Motil 2022 May 20:e14416. Epub 2022 May 20.

Department of Surgery, Oncology and Gastroenterology, University of Padua, Padua, Italy.

Systemic sclerosis (SSc) is a chronic and generalized disease affecting the connective tissue of the skin and many internal organs, in particular the gastrointestinal tract. The esophagus is involved in up to 80% of the cases and represents a major cause of serious morbidities that deeply impact on the quality of life and survival of patients. Indeed, the presence of esophageal dysfunction is a good prognostic indicator in SSc, primarily due to its impact on pulmonary disease. Read More
