Effects of Huashi Runzao Prescription on apoptosis and function of the submandibular gland in Sjögren′s syndrome model mice by regulating Hippo-YAP/TAZ expression
To explore the effects of modulating the Hippo-YAP/TAZ pathway using
Huashi Runzao
Prescription (HRP) on the apoptosis and salivary secretion function of submandibular gland cells in a naive non-obese diabetic (NOD/Ltj) mouse model of Sjögren′s syndrome (SS).
Methods
2
Eight-week-old female BALB/c mice were selected as the blank group. Eight-week-old female NOD/Ltj were randomly divided into the model
HRP-L
HRP-M
HRP-H
and hydroxychloroquine sulphate (HCQ) groups. After eight weeks of drug administration
the water consumption and salivary flow rate of each group were recorded. The histopathological damage of the submandibular gland in each group was determined using hematoxylin and eosin staining
the apoptosis rate of the submandibular gland was determined using TUNEL staining
and AQP5
Bax
Bcl-2
beclin-1
YAP
p-YAP
and TAZ expressions in submandibular gland tissues were determined using immunohistochemistry and Western blotting.
Results
2
Compared with the blank group
the Hippo-YAP/TAZ pathway was inhibited in the submandibular gland tissues of the model group
lymphocyte infiltration increased
water consumption increased
salivary flow rate decreased
AQP5 expression decreased
and submandibular gland cells apoptosis rate increased (
P
<
0.05). Compared with all other administered groups
in the HRP-M group
the Hippo-YAZ/TAZ pathway was significantly activated
lymphocyte infiltration in submandibular gland tissues was reduced
water consumption was reduced
the salivary flow rate and AQP5 expression were increased
and the apoptosis rate of submandibular gland cells was reduced (
P
<
0.05).
Conclusion
2
HRP reduced the pathological damage and apoptosis of submandibular gland cells in SS model mice. It improved the overall secretory function of submandibular gland tissues
which may be related to Hippo pathway activation and downregulating YAP/TAZ expression.
