The role of steroidogenic factor-1 (SF-1) in gonadotropin-releasing hormone (GnRH) receptor gene regulation by Pheiffer, Carmen P

“…DNasel footprinting reveals that the major DNA-binding activity in αT3-1 cells on the GnRHR promoter occurs at the SF-1-like site. The SF-1-like sequence specificity of the interaction is demonstrated by gel redardation and DNasel footprinting assays using specific and mutated oligonucleotides as competitors. …”

In vitro modelling of cellular haemozoin and inhibition by β-haematin inhibitors and their derivatives by Openshaw, Roxanne

“…Further investigations into the exchangeable haem amounts as a function of intracellular test compound amounts at the IC50 values of these β-haematin inhibitors highlighted that there was an apparent 1:1 relationship with the amount of intracellular exchangeable haem, indicative of complex formation. …”

Investigating the effects of enhanced catecholamine stimulation in stem cell-derived cardiomyocytes by Samodien, Kauthar

“…A model of sympathetic overdrive was induced by treating the EBs with a synthetic catecholamine, isoprenaline (10μM isoprenaline for 72 hours) as was determined by the results of a preliminary dose-response test. The EB growth patterns were monitored using light microscopy and the images were analysed with ImageJ software. …”
