(h) Kaplan‒Meier survival analysis showing that genistein significantly prolonged the lifespan of N171-82Q mice ( n = 10 mice per group: N171-82Q and N171-82Q + genistein). (i) Genistein treatment improved body weight maintenance in N171-82Q mice starting at 20 weeks of age. (j) Proposed model illustrating therapeutic modulation of the WNT5B-NFATc2-MMP14 signaling axis. Upregulation of WNT5B by mHTT activates noncanonical WNT signaling via NFATc2, inducing MMP14 transcription in reactive astrocytes. Elevated MMP14 leads to ECM disruption, mHTT aggregation, and MSN damage. Genistein antagonizes NFATc2 activity and suppresses MMP14 expression, thereby mitigating ECM degradation and neurodegeneration in HD. Schematic created with BioRender.com

    Figure Lengend Snippet: Genistein ameliorates motor deficits and extends lifespan in HD mice. ( a ) Experimental design for the behavioral assessment of N171-82Q mice treated with genistein or saline via I.P. injection from postnatal days 30 to 90. (b) Forelimb and hindlimb clasping behavior was quantified in the tail suspension test (WT, N = 7; N171-82Q, N = 4; N171-82Q + genistein, N = 6). One-way ANOVA (*, p < 0.05; **, p < 0.01; ***, p < 0.001). (c) Representative still images from the accelerated wheel test (left) and computer-assisted footprint analysis (right) in the wheel running paradigm across three experimental groups. (d) Genistein treatment improved stride length and stride width in N171-82Q (WT, N = 7; N171-82Q, N = 4; N171-82Q + genistein, N = 7). One-way ANOVA (***, p < 0.001). The data are presented as the means ± SEMs. (e) Experimental design for behavioral tests in AAV-mHTT (103Q)-induced HD mice following one month of i.p. administration of genistein or saline. (f) Rotarod performance showing that genistein significantly restored the latency to fall in 103Q mice relative to that in 103Q vehicle control mice (25Q, N = 10; 103Q, N = 9; 103Q + genistein, N = 10). One-way ANOVA (*, p < 0.05). (g) Tail suspension test showing that genistein alleviated forelimb and hindlimb clasping in 103Q mice compared with 103Q vehicle controls (25Q, N = 10; 103Q, N = 9; 103Q + genistein, N = 10). *, p < 0.05; **, p < 0.01; ***, p < 0.001.
