Optical control of Hippo signaling in NIH 3T3
cells. (A) Schematic
depiction of the optical control of Hippo deactivation induced by
PA. (B) Confocal microscopy images of NIH 3T3 cells treated with BSA
(4 mg/mL) or the indicated lipids (50 μM) for 1 h and immunostained
for YAP. (C) Quantification of nuclear YAP levels in (B). The plots
show mean nuclear YAP intensity in each cell. Black horizontal bars
indicate mean (n = 645), and vertical error bars
indicate standard deviation. (D) Confocal microscopy images of NIH
3T3 cells treated with BSA (4 mg/mL) or indicated lipids (10 μM)
for 1 h with or without 365 nm light (5 ms every 15 s) and immunostained
for YAP. (E,F) Quantification of nuclear YAP levels in (C) and (D).
The plots show mean nuclear YAP intensity in each cell. Black horizontal
bars indicate mean (n = 342 (C) and 465 (D)), and
vertical error bars indicate standard deviation. Statistical significance
was calculated using one-way ANOVA, followed by Tukey’s HSD
test. Green, YAP; blue, DAPI (nuclei). Scale bars: 50 μm.
