Fig. 7. The human ISWI homologs SMARCA1 and SMARCA5 differentially rescue sleep and memory.

(A) Representative sleep traces with ISWI knockdown (red) compared to SMARCA1WT (blue) and SMARCA5WT (green) expression in the setting of ISWI knockdown or overexpression alone (black) with (B) quantification of total sleep and (C) activity index across experimental and control groups (n = 104, 48, 29, 102, and 55 from left to right). (D) Representative images of FasII immunostaining of adult brains with pan-neuronal ISWI knockdown (left), SMARCA1WT rescue (middle), and SMARCA5WT rescue (right; scale bar, 50 μm) and (E) quantification of MB lobe volume across groups (n = 5, 21, 16, and 14 from left to right). (F) Quantification of proboscis extensions in ISWI knockdown (red, n = 30) compared to genetic control (black, n = 37), SMARCA1WT rescue (blue, n = 29), and SMARCA5WT rescue (n = 26) (two-way ANOVA with post hoc multiple comparison test). (G) Representative sleep traces of pan-neuronal ISWI knockdown (red) compared to rescue with SMARCA5WT (green) or SMARCA5del268-319 (purple) and overexpression of WT or mutant constructs alone, with (H) quantification of total sleep duration (left) and night sleep duration (right) (n = 104, 102, 55, 41, and 31 from left to right). For graphs in this figure, letters represent statistically similar groups.
