Fig 1: Correlation analysis between noise level and PKCε pathway markers: (a) p-PKC and noise level, (b) p-CREB and noise level, and (c) p-STAT1 and noise level. ⚫ indicates data points included in the analysis. p-CREB = phosphorylated cAMP response element binding protein, p-PKC = phosphorylated protein kinase C, p-STAT1 = phosphorylated signal transducer and activator of transcription 1.
