Figure Lengend Snippet: Hearing phenotype of C57BL6/J-129Sv Slc7a8 knockout mice. ( A ) Representative image of western bloting of total membranes from kidney, brain and intestine of wild-type (+/+) and Slc7a8 knock out (-/-) mice in the absence (-) or presence (+) of 100 mM dithiothreitol reducing agent (DTT) of three independent biological samples for both sexes (male and female). Protein (50 μg) were loaded in 7% acrylamide SDS-PAGE gel. Molecular mass standard (KDa) are indicated. Red arrows point SLC7A8/CD98hc heterodimer band as well as the light subunit SLC7A8. Upper panel: Rabbit anti-SLC7A8. Bottom panel: Mouse anti-βactin. ( B ) Pre-Pulse Inhibition of the acoustic startle response (PPI). Mean and SEM are represented. Pulse: 120 dB single pulse. Pre-pulse inhibition test: six different pre-pulse intensities (70 to 90 dB) in pseudo random order with 15 s inter-trial intervals. Wild type (white circles, n = 19) and Slc7a8 −/− (blue circles, n = 15) from 4- to 7-month-old are represented. Significant differences were determined using paired Student’s t-test, ***p
