Figure Lengend Snippet: Altered protein expression and EGFR signaling in Sorcin-deficient lung development A ) Confocal microscopy of 3-week-old lung tissue from WT and Sri⁻ / ⁻ mice. Sri⁻ / ⁻ lung tissue shows reduced SP-B (red) expression compared to WT. Scale bars, 20 μm B ) Western blot analysis of lung lysates from 3-week-old WT and Sri⁻ / ⁻ mice. Sri⁻ / ⁻ mice exhibit decreased EGFR, PANRAS and RAB5C protein levels compared to WT. Densitometry quantification is shown (mean ± SEM). ** p < 0.01 (Student’s t-test), *** p < 0.001 (determined by Student’s t-test) C-E ) Confocal microscopy of 3-week-old lung sections: WT mice show epithelial localization of EGFR (green) (C), RAB5C (green) (D) and PANRAS (red) protein (E). In Sri⁻ / ⁻ mice, these proteins are significantly reduced. Scale bars, 20 μm
