In vitro effects of heparin-binding epidermal growth factor on adhesion stage of implantation.

A member of the epidermal growth factor (EGF) family, the heparin-binding EGF (HB-EGF) is expressed in the uteri of both humans and mice during the implantation process. To study the effects of HB-EGF on adhesion stage, we developed an in vitro implantation model employing Ishikawa cell line and JAR cell line, which may attach to Ishikawa cells. For 1, 6, 12, and 24 hours, co-cultures of JAR spheroids grown on Ishikawa monolayers were treated with 1, 10, and 100 ng∕mL doses of HB-EGF.

Antitumor activity of irinotecan with ellagic acid in C6 glioma cells.

Objective: Irinotecan-based combination chemotherapies in malignant gliomas need to be examined. The aim of this study was to investigate the synergetic effect of ellagic acid, a natural polyphenolic antioxidant compound, with irinotecan, an inhibitor of topoisomerase I enzyme, on the growth, cadherin switch, and angiogenic processes of a glioma cell line.

Methods: A combination of 100 μM ellagic acid and 100 μM irinotecan was applied to rat C6 glioma cells for 24th, 48th, and 72nd h.

Cordycepin prevents the esophageal stricture formation in the alkali-burn rat model by exerting anti-inflammatory and antifibrotic effects.

Purpose: To investigate the efficacy of cordycepin, an adenosine analogue, on prevention of esophageal damage and stricture formation due to esophageal caustic burns in rat model comparing with prednisolone.

Methods: Caustic esophageal burn was introduced by 37.5% of NaOH to distal esophagus.

Ellagic Acid Enhances the Antitumor Efficacy of Bevacizumab in an In Vitro Glioblastoma Model.

Background: The anticarcinogenic effect of ellagic acid (EA), a natural phenol of fruits and vegetables, has been investigated in several types of tumors. The combined effect of EA with bevacizumab (BEV), a common drug used in treatment of recurrent glioma, on glioblastoma has not been reported. This study observed the combined effect of EA with BEV on the expression profile of the C6 glioma cell line.

Combining Ellagic Acid with Temozolomide Mediates the Cadherin Switch and Angiogenesis in a Glioblastoma Model.

Objective: We aimed to evaluate the combined effect of ellagic acid (EA) and temozolomide (TEM) on the cadherin switch and angiogenesis in the C6 glioma cell line.

Methods: A total of 100 μM EA and 100 μM TEM were applied to rat C6 glioma cells for 24, 48, and 72 hours. Cell proliferation was detected by 5-bromo-2'-deoxyuridine immunohistochemistry.
