Background: Epithelial-mesenchymal transition (EMT) is considered to play a critical role in cancer progression and metastasis. However, the impact of EMT on the prognosis of hepatocellular carcinoma (HCC) is still elusive. In this study, we examined the relationship between the expression of EMT markers and recurrence-free survival (RFS) and overall survival (OS) in HCC patients after hepatic resection.
Summary: The mRNA expression of 15 genes related to EMT was assessed by quantitative real-time polymerase chain reaction in cancerous tissues from 72 patients who underwent hepatic resection of HCC between January 2005 and December 2010 at our hospital. The upregulation of TWIST and the downregulation of tight junction protein ZO-1 (TJP1) were significantly associated with shorter RFS as well as OS. Increased levels of TWIST and decreased levels of TJP1 should be predictive markers for poor prognosis in patients with HCC after hepatectomy; those could serve as potential biomarkers for the treatment of HCC. Key Messages: A low level of TJP1 and high level of TWIST expression were prognostic factors predicting HCC after hepatic resection.

Inflammatory bowel disease (IBD) is a chronic inflammation with a high incidence rate. Many probiotics, including (), have shown promise in IBD treatment. The therapeutic effects of most probiotics are greatly decided by the available live cells in the disease lesion, which is compromised as they pass through the gastric juice and intestinal tract, resulting in a loss of activity.

Technical hurdles in a culture of epithelial cells include dedifferentiation and loss of function. Biomimetic three-dimensional (3D) cell culture methods can enhance cell culture efficiency. This study introduces an advanced two-layered culture system intended to cultivate epithelial cells as tissue-like layers with the culture of fibroblasts within a 3D environment.

Polarized epithelial cells are compartmentalized into apical and basement membranes with asymmetrically distributed proteins. This study aimed to establish a method for culturing epithelial cells at the fluorinated oil (Novec-7500) microdroplet surface for the formation of epithelial polarity, which is desirable for regenerative medicine and drug discovery research. Microdroplet surfaces treated with fibronectin, which regulates a variety of cell behaviors through direct interactions with cell surface integrin receptors, were prepared for culturing epithelial cells.

Purpose: To explore the destructive and protective effects and therapeutic targets of IL-36 cytokines in dry eye disease using a murine dry eye model.
Methods: A dry eye model was established in C57BL/6 mice exposed to desiccating stress (DS) with untreated mice as controls. A topical challenge model was performed in normal mice with exogenous rmIL-36α, rhIL-38 and 2% ectoine, or PBS vehicle.
