结论
2
消瘰丸可能作用于PI3K/Akt/mTORC1信号通路,发挥其治疗结节性甲状腺肿的作用,且表现为剂量依赖。
Objective
2
By observing the effect of Xiaoluowan on phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt)/mammalian target of rapamycin complex 1 (mTORC1) pathway in experimental goiter rats, this study aims to explore its therapeutic effect on experimental goiter rats.
Method
2
Sixty 5-month-old SD rats of SPF grade were purchased, half males and half females, of which 10 were used as a normal group, and the remaining rats were administrated with propylthiouracil (PTU) solution to induce nodular goiter. After successful modeling, rats were randomly divided into a model group, levothyroxine sodium tablets group, Xiaoluowan low-dose group, medium-dose group, and high-dose group, ten rats each. The levothyroxine sodium tablets group was given 15 μg·kg
-1
levothyroxine sodium tablets by gavage. The Xiaoluowan low-, medium-, and high-dose groups were given (
ig
) Xiaoluowan low-dose (10 g·kg
-1
), medium-dose (20 g·kg
-1
), and high-dose (30 g·kg
-1
) Xiaoluowan, and the normal group and model group were administered (
ig
) with the same volume of 0.9% sodium chloride solution. Four weeks after the intervention, rats were sacrificed by routine intraperitoneal anesthesia using 5% phenobarbital. Subsequently, the histopathology was observed under a microscope, and serum thyroid hormone levels were measured using a Roche electrochemiluminescence immunoassay analyzer. Serum cytokines were detected by enzyme-linked immunosorbent assay (ELISA), and neurotransmitters were measured using a high-performance liquid chromatograph. The protein level of PI3K/Akt/mTORC1 pathway was determined by Western blot.
Result
2
As compared with the normal group, the levels of basic fibroblast growth factor (bFGF), vascular endothelial growth factor (VEGF), insulin-like growth factor (IGF-1), 5-hydroxytryptamine (5-HT), and thyroid stimulating hormone (TSH) were increased, and PI3K, Akt, and mTORC1 protein levels were up-regulated in the model group, while the levels of norepinephrine (NE), triiodothyronine (T
3
), tetraiodothyronine (T
4
), free triiodothyronine (FT
3
), and free thyroid hormone (FT
4
) were decreased (
P
<
0.05). Compared with the model group, the levothyroxine sodium tablets group, and Xiaoluowan low-, medium-, and high-dose groups exhibited reduced levels of bFGF, VEGF, IGF-1, 5-HT, and TSH, and down-regulated PI3K, Akt, and mTORC1 protein levels, and increased NE, T
3
, T
4
, FT
3
, and FT
4
levels (
P
<
0.05).
Conclusion
2
Xiaoluowan may act on the PI3K/Akt/mTORC1 signaling pathway to play its role in the treatment of nodular goiter, and it is dose-dependent.
