ABCG2 gene amplification and expression in esophageal cancer cells with acquired adriamycin resistance.

Resistance to chemotherapeutic agents is the main reason for treatment failure in patients with cancer. The primary mechanism of multidrug resistance (MDR) is the overexpression of drug efflux transporters, including ATP‑binding cassette transporter G2 (ABCG2). To the best of our knowledge, the MDR mechanisms of esophageal cancer have not been described.

Reversal of multidrug resistance by the anti-malaria drug artesunate in the esophageal cancer Eca109/ABCG2 cell line.

Broad tissue expression of membrane progesterone receptor Alpha in normal mice.

The broad tissue distribution of membrane progesterone receptor alpha (mPRalpha) in vertebrates suggests multiple physiological functions of the receptor. Current knowledge regarding the receptor distribution, however, is largely obtained via non-histological assays. In this study, the tissue distribution of mPRalpha in mice of both sexes was described using both histological and non-histological methods.

Optimizing the time of Doxil injection to increase the drug retention in transplanted murine mammary tumors.

Sex hormonal milieus during the female fertility cycle modulate the tumor vascular permeability of breast cancer. It has been proposed that the liposomal formulated doxorubicin (ie, Doxil), given at the menstrual/estrous stage with the predicted highest tumor vascular permeability, allows significantly increased drug retention in the breast tumor. In the current study, syngeneic murine 4T1 mammary tumors were established on the backs of female BALB/c mice and Doxil was administered at particular mouse estrous cycle stages.

Identification of two antagonists of the scavenger receptor CD36 using a high-throughput screening model.

CD36, a class B scavenger receptor, is an integral membrane protein that mediates the endocytosis of modified lipoproteins. The functions of CD36 are complex and have been associated with atherosclerosis. In the current study, we developed a high-throughput screening (HTS) assay to identify small molecule antagonists by expressing human CD36 using a Bac-to-Bac baculovirus expression system in Spodoptera frugiperda (Sf9) cells.
