MSN-LEP-PIO treatment beginning at the asymptomatic
state of disease
significantly enhances motor performance in TDP-43A315T mice. (A) Time monitoring of body weight was carried out in WT controls
and TDP-43A315T mice IP treated with MSN-LEP-PIO or PBS.
Starting weight in week 7. No significant differences were observed
between MSN-LEP-PIO- or PBS-treated TDP-43A315T mice. (B)
Average disease onset and disease duration (C) was determined in WT
controls and TDP-43A315T mice IP treated with MSN-LEP-PIO
or PBS using body weight as a physiological parameter. The average
disease duration of the animal was calculated as the time between
the onset of the disease (defined as the last day of individual peak
body weight before a gradual loss occurs) and the day of death. Comparatively,
the disease duration was higher in TDP-43A315T mice in
response to MSN-LEP-PIO treatment. (D) Behavioral assessment of the
motor function was performed in WT controls and TDP-43A315T mice IP treated with MSN-LEP-PIO or PBS over time. Significant differences
between MSN-LEP-PIO- and PBS-treated mice were seen. Values are expressed
as mean ± SEM. A comparison between groups was performed by two-way
ANOVA, where *p < 0.05 vs PBS-treated WT control
mice; $p < 0.05 vs MSN-LEP-PIO-treated
WT control mice; and #p < 0.05 vs MSN-LEP-PIO-treated
TDP-43A315T mice. Corresponding graphs as per (A), i.e.,
control–PBS (n = 3, white square and solid
line), control–MSN-LEP-PIO (n = 3, blue square
and dashed line), TDP-43A315T–PBS (n = 3, white circles and solid line), and TDP-43A315T–MSN-LEP-PIO
(n = 6, orange circles and dashed line).
