Administration of LGG improved serum bone turnover markers and
biomechanical properties at 8 weeks.
Serum levels of P1NP (marker of bone formation) (a), CTX-1 (marker of
bone resorption) (b), and the TDF concentration (serum TDF concentration
was undetectable because no TDF was administered in the Sham group) (c).
(d) The biomechanical parameters of maximum load, energy to ultimate
load, Young’s modulus, stiffness, and breaking energy were evaluated
using a 3-point flexural test. n = 8–10 mice per group
in all panels. Data are expressed as mean ± SD. All data were normally
distributed according to the Shapiro–Wilk normality test and analyzed
using two-way ANOVA and post hoc tests applying the LSD
correction for multiple comparisons.
*p < 0.05 compared with the Sham
group.
#p < 0.05 compared with the LGG+TDF
group.
%p < 0.05 compared with the E.
coli+TDF group.
$p < 0.05 compared with the TDF group.
ANOVA, analysis of variance; CTX-1, cross-linked carboxy-terminal
telopeptide of type 1 collagen; LGG, Lactobacillus
rhamnosus GG; LSD, least significant difference; P1NP,
procollagen 1 N-terminal peptide; SD, standard deviation; TDF, tenofovir
disoproxil fumarate; ZOL, zoledronic acid.
