Klotho attenuates glucocorticoid-induced osteoblast cytotoxicity via Wnt signaling pathway modulation
Abstract
Background
Glucocorticoids
are
commonly
prescribed
in
clinical
settings;
however,
their
prolonged
use
at
high
doses
can
adversely
affect
human
health.
One
significant
complication
following
glucocorticoid
therapy
is
glucocorticoid-induced
osteoporosis
(GIO),
which
second
incidence
only
to
senile
osteoporosis.
Objective
Based
on
previous
research
indicating
that
Klotho
alleviates
dexamethasone-induced
osteoblast
cytotoxicity
through
the
NF-kB
pathway,
we
aimed
explore
underlying
mechanisms
greater
depth.
Methods
We
assessed
impact
of
Lithium
chloride
(LiCl),
a
Wnt
pathway
activator,
cell
and
viability.
Cytotoxicity
was
specifically
quantified
by
Annexin
V/PI
flow
cytometry.
performed
qRT-PCR
Western
blotting
analyses
scrutinize
expressions
genes
proteins
associated
with
both
canonical
non-canonical
signaling
pathways.
Results
Dexamethasone
treatment
induced
an
upregulation
ligand,
Wnt5a,
downregulation
Wnt3a,
along
its
downstream
marker,
β-catenin.
Transfection
counteracted
these
effects.
Conclusion
has
potential
modulate
pathways,
thereby
counteracting
glucocorticoids.
