In rodents, CHRNs are involved in bitter taste transduction of nicotine and ethanol. Currently, it is not clear if CHRNs are expressed in human taste cells and if they play a role in transducing the bitter taste of nicotine and ethanol or in the synthesis and release of neurohumoral peptides. Accordingly, we investigated the expression and functional role of CHRNs in HBO cells. Using molecular ...

It has been difficult to separate/identify the roles of ClC-2 and CFTR in Cl(-) transport studies. Using pharmacological agents, we aimed to differentiate functionally between ClC-2 and CFTR Cl(-) channel currents. Effects of CFTR inhibitor 172 (CFTRinh172), N-(4-methylphenylsulfonyl)-N'-(4-trifluoromethylphenyl)urea (DASU-02), and methadone were examined by whole cell patch clamp on Cl(-) curr...

We investigated the in vitro transport characteristics of catalposide in HEK293 cells overexpressing organic anion transporter 1 (OAT1), OAT3, organic anion transporting polypeptide 1B1 (OATP1B1), OATP1B3, organic cation transporter 1 (OCT1), OCT2, P-glycoprotein (P-gp), and breast cancer resistance protein (BCRP). The transport mechanism of catalposide was investigated in HEK293 and LLC-PK1 ce...

objective: biebersteinia (geraniaceae) has a history of use in traditional medicine in some countries including iran. in the present study, cytotoxic and apoptogenic properties of hydro-ethanol extract of b. multifidi was investigated on human prostate cancer cell lines (pc3 and du 145) and human embryonic kidney 293 (hek293) cells. materials and methods: cells were cultured in rpmi-1640 medium...

purification and isolation of cellular target proteins for monoclonal antibody (mab) production is a difficult and time-consuming process. immunization of mice with murine cell lines stably transfected with genes coding for xenogenic target molecules is an alternative method for mouse immunization and mab production. here we present data on transfection efficiency of some commercial reagents us...
