Human apoptosis antibody array-membranes studying the apoptotic effect of marine bacterial exopolysaccharides in HepG2 cells.

Background: Hepatocellular carcinoma (HCC) is considered as the third leading cause of cancer-related deaths, in spite of great advances in its treatment. The carbohydrate polymers, exopolysaccharides (EPSs), showed anticancer activity in diverse cancers.

Objective: The purpose of this study is to investigate a panel of 43 apoptotic proteins to assess the possible apoptotic induction effect of bacterial EPSs showing promising cytotoxic effects in HepG2 cells in our previous study, in an attempt to introduce exopolysaccharides as new source for cancer treatment.

Acidic Exopolysaccharide Produced from Marine 3MS 2017 for the Protection and Treatment of Breast Cancer.

Purpose: This study was planned to investigate the anti-breast-cancer property of acidic exopolysaccharide produced from marine 3MS 2017 (BAEPS) in an animal model, which previously showed in-vitro anti-breast-cancer activity, by studying its potential participation in various targeted mechanisms.

Methods: Mammary carcinoma in female Sprague-Dawley rats, both in prophylactic and in curative designs, was chemically induced using 7,12-dimethylebenz-(a)-anthracene (DMBA). 3MS 2017 anti-breast-cancer property was evaluated by studying its effects on cancer-growth-rate-limiting enzymes (aromatase and Na/K ATPase), sexual hormones (estrogen and progesterone), antioxidant and inflammatory biomarkers (cyclooxygenase-1; COX-1 and cyclooxygenase-2; COX-2).

Study of the chemical structure of exopolysaccharide produced from streptomycete and its effect as an attenuate for antineoplastic drug 5-fluorouracil that induced gastrointestinal toxicity in rats.

Chemotherapeutic medications, including 5 - fluorouracil (5FU), are the same old technique to most cancers and are associated with numerous peripheral toxicities. We investigated exopolysaccharide (EPSST) produced from the isolated streptomycete of the Mediterranean Sea for the capability to lower the severity of mucositis . The streptomycete was isolated from Mediterranean Sea sediment from the beaches of Port Said Governorates, Egypt and identified morphologically, physiologically, and biochemically and confirmed by molecularly 16S rDNA analysis.
