Medicated Serum of Bupleuri Radix Regulates HFL1 Apoptosis and Fibroblast-myofibroblast Transition via Smad3/Rheb Axis
) was used to stimulate human fetal lung fibroblast 1 (HFL1) for simulating the pathological process of idiopathic pulmonary fibrosis (IPF) and thereby the effects and mechanism of medicated serum of Bupleuri Radix against IPF were investigated.
Method
2
TGF-
β
1
(10 μg·L
-1
) was employed to stimulate HFL1, and cells were treated with medicated serum of Bupleuri Radix (5%, 10%, 15%, 20%) for 24 h. Then cell proliferation rate was determined with cell counting kit-8 (CCK-8). Subsequently, cells were classified into the control group (20% blank serum), TGF-
β
1
group (20% blank serum and 10 μg·L
-1
TGF-
β
1
), TGF-
β
1
+ medicated serum of Bupleuri Radix group (5% blank serum, 15% medicated serum, and 10 μg·L
-1
TGF-
β
1
), and TGF-
β
1
+ SIS3 group (3 μmol·L
-1
SIS3, 20% blank serum, 10 μg·L
-1
TGF-
β
1
). Based on in situ end labeling (TUNEL) staining, the apoptosis rate was examined, and mRNA expression of apoptosis-related proteins B-cell lymphoma 2 (Bcl-2), Bcl-2 associated X protein (Bax) and myofibroblast marker
α
-smooth muscle actin (
α
-SMA) was detected by Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR). The protein expression of
α
-SMA, Ras homolog enriched in brain (Rheb), and phosphorylated (p)-Smad3 was determined by immunofluorescence. Expression of Rheb, p-Smad3, and Smad3 was examined by Western blot.
Result
2
The cell proliferation rate of TGF-
β
1
group increased compared with that of the control group (
P
<
0.05). The cell proliferation rate of TGF+15% medicated serum of Bupleuri Radix group and TGF+20% medicated serum of Bupleuri Radix group decreased compared with that of the TGF-
β
1
group (
P
<
0.01). Compared with the control group, TGF-
β
1
group showed decrease in apoptosis rate, increase in mRNA expression of Bcl-2 and
α
-SMA, reduction in Bax mRNA expression, and rise of
α
-SMA and Rheb protein expression and p-Smad3 level (
P
<
0.05). Compared with TGF-
β
1
group, TGF-
β
1
+ medicated serum of Bupleuri Radix group and TGF-
β
1
+ SIS3 group demonstrated high apoptosis rate, low Bcl-2 and
α
-SMA mRNA expression, high Bax mRNA expression, and low
α
-SMA and Rheb protein expression and p-Smad3 level (
P
<
0.05).
Conclusion
2
Medicated serum of Bupleuri Radix can inhibit TGF-
β
1
-induced HFL1 proliferation and fibroblast-myofibroblast transition and promote fibroblast apoptosis by regulating the Smad3/Rheb axis.
