BACKGROUND/AIM One reason of poor survival rate of patients with pancreatic cancer is the development of chemoresistance. The aim of the present study was to investigate the effects of eribulin mesylate in gemcitabine-refractory advanced pancreatic cancer cell lines. MATERIALS AND METHODS Three human pancreatic cancer cell lines (AsPC-1, Panc-1, and SUIT-2) and human pancreatic endoderm (hPE)...

A gemcitabine (GEM)-resistant human pancreatic cancer cell line (PANC-1RG7) was established in vitro by gradually increasing GEM concentrations and cloning cell cultures to develop a cellular model of acquired drug resistance studies. We found that PANC-1RG7 cells exhibited significantly different morphological characteristics from parental cells. PANC-1RG7 cells grew slowly (p<0.05), yet the c...

BACKGROUND Pomegranate extract (PE) is a standardized whole-fruit extract of pomegranate, a fruit with known anticancer properties. MATERIALS AND METHODS PANC-1 and AsPC-1 human pancreatic cancer cells were used as in vitro models to test the effects of PE. RESULTS PE treatment induced cell cycle arrest and inhibited cell proliferation in PANC-1 cells. PE treatment increased the proportion ...

Baicalein, a flavone ingredient of Scutellaria baicalensis Georgi, is a promising anti-cancer agent. However, its potential anti-pancreatic cancer effects and the underlying mechanisms are still unclear. In this study, we showed that Baicalein not only induced apoptosis, but also suppressed proliferation, migration and invasion of two pancreatic cancer cell lines BxPC-3 and PANC-1 in a dose- an...

Curcumin, a phenolic compound extracted from Zingiberaceae turmeric, has strong anti-inflammatory, antioxidant and antitumor properties. However, the anticarcinogenic mechanism of curcumin has yet to be fully elucidated. Epithelial-mesenchymal transition (EMT) induced by transforming growth factor-β1 (TGF-β1) is involved in the promotion of tumor invasion and metastasis, and is closely related ...

Intrinsic drug resistance of pancreatic ductal adenocarcinoma (PDAC) warrants studies using models that are more clinically relevant for identifying novel resistance mechanisms as well as for drug development. Tumor spheroids (TS) mimic in vivo tumor conditions associated with multicellular resistance and represent a promising model for efficient drug screening, however, pancreatic cancer cells...

PURPOSE Pancreatic cancer is an aggressive human malignancy that is generally refractory to chemotherapy. Histone deacetylase inhibitors are novel agents that modulate cell growth and survival. In this study, we sought to determine whether a relatively new histone deacetylase inhibitor, suberoylanilide hydroxamic acid (SAHA), inhibits pancreatic cancer cell growth. EXPERIMENTAL DESIGN The eff...

Chlorotoxin (CTX) is a 36-amino acid peptide derived from Leiurus quinquestriatus (scorpion) venom, which inhibits low-conductance chloride channels in colonic epithelial cells. It has been reported that CTX also binds to matrix metalloproteinase-2 (MMP-2), membrane type-1 MMP, and tissue inhibitor of metalloproteinase-2, as well as CLC-3 chloride ion channels and other proteins. Pancreatic can...
