Effect and Mechanisms of Lycii Fructus on Hepatoma HepG2 Cell Line-induced Cachexia in Mice
To investigate the inhibitory effect and mechanism of the extracts from fresh Lycii Fructus(LBL) on hepatoma HepG2 cell-induced cachexia in mouse.
Method:
2
The human hepatoma cell line HepG2 was injected into BALB/C mice to establish the cachexia model. Then the LBL was fed to the models respectively in low dose (5 mg·kg
-1
) or high dose (25 mg·kg
-1
). After 28 days of continuous feeding
the mice's body weight was detected. The expression levels of creatine kinase (CK)
interleukin-1
β
(IL-1
β
)
interleukin-6 (IL-6) and tumor necrosis factor-
α
(TNF-
α
) were evaluated by enzyme linked immunosorbent assay (ELISA). The muscle degradation and the expression of p38 mitogen-activated protein kinase (p38 MAPK) were detected by immunohistochemistry staining. The expression levels of phospho-p38 mitogen-activated protein kinase (p-p38 MAPK) and nuclear factor-
κ
B (NF-
κ
B) were determined by Western blot.
Result:
2
Compared with cachexia group
the loss of body weight and muscle decomposition were significantly inhibited both in the low dose LBL group and high dose LBL group(
P
<
0.05
P
<
0.01). The level of plasma CK decreased significantly both in the low-dose LBL group and the high-dose LBL group (
P
<
0.01). ELISA tests revealed lower expression levels of IL-1
β
IL-6 and TNF-
α
in both the low-dose LBL group and the high-dose LBL group (
P
<
0.05
P
<
0.01). Immunohistochemistry staining showed that the expression of p38 MAPK was inhibited both in the low-dose LBL group and the high-dose LBL group (
P
<
0.05). Western blot indicated that the expressions of p-p38 MAPK and NF-
κ
B were inhibited both in the low-dose LBL group and the high-dose LBL group (
P
<
0.01). We found that the high-dose LBL group shows a higher inhibitory capability than the low-dose LBL group.
Conclusion:
2
LBL could inhibit the cachexia induced by hepatoma HepG2 cell line in mouse
suggesting LBL could reduce major cytokine and plasma inflammatory factors through p-p38 MAPK pathway.
