Camptothecin UNC1999 Paclitaxel

AIM: To assess the results of dihydromyricetin (DHM)
like a hepatoprotective candidate in lowering hepatic
injury and accelerating hepatocyte proliferation following
carbon tetrachloride (CCl4) treatment.
Solutions: Camptothecin solubility C57 BL/6 mice had been utilised on this examine.
Mice had been orally administered with DHM (150 mg/kg)
for 4 d just after CCl4 treatment method. Serum and liver tissue
samples had been collected on days 1, 2, 3, 5 and 7 immediately after
CCl4 treatment. The anti-inflammatory effect of DHM
was assessed right by hepatic histology detection and
indirectly by serum amounts of aspartate aminotransferase
(AST), alanine aminotransferase (ALT), albumin, and
superoxide dismutase (SOD). Inflammatory cytokines,
such as interleukin (IL)-1��, IL-6 and tumor necrosis
factor-�� (TNF-��), have been detected using ELISA kits.

Proliferating cell nuclear antigen (PCNA) staining
was applied to evaluate the part of DHM in selling
hepatocyte proliferation. Hepatocyte apoptosis wasXie J et al . Dihydromyricetin alleviates CCl4-induced ALI
measured by TUNEL assay. In addition, apoptosis
proteins Caspases-3, 6, 8, and 9 have been detected by
Western blot. SP600125 had been made use of to verify whether
DHM regulated liver regeneration by JNK/TNF-��
Success: DHM showed a strong anti-inflammatory
result on CCl4-induced liver injury in mice. DHM could
substantially lessen serum ALT, AST, IL-1��, IL-6 and
TNF-�� and maximize serum albumin, SOD and liver SOD
when compared to the control group soon after CCl4 remedy
(P < 0.05).

PCNA results indicated that DHM could
significantly boost the variety of PCNA good
cells in comparison with the control (348.9 �� 56.0 vs 107.1
�� 31.4, P < 0.01). TUNEL assay showed that DHM
dramatically reduced the number of apoptotic cells
after CCl4 treatment compared to the control (365.4
�� 99.4 vs 90.5��13.8, P < 0.01). Caspase activity
detection showed that DHM could reduce the activities
of Caspases- 8, 3, 6 and 9 compared to the control (P
< 0.05). The results of Western blot showed that DHM increased the expression of JNK and decreased TNF-��
expression. However, DHM could not affect TNF-��
expression after SP600125 treatment. Furthermore,
DHM could significantly improve the survival rate of
acute liver failure (ALF) mice (73.3% vs 20.0%, P <
0.0001), and SP600125 could inhibit the effect of DHM.

CONCLUSION: These findings show that DHM
alleviates CCl4-induced liver damage, suggesting that DHM
is often a promising UNC1999 Histone Methyltransf candidate for reversing liver damage and

Core tip: Our exploration confirmed that dihydromyricetin
(DHM) plays an anti-inflammatory role while in the carbon
tetrachloride (CCl4) induced acute liver damage mice. It
was proven that DHM could alleviate CCl4-induced acute
liver damage by minimizing apoptosis and accelerating
prol iferation of hepatocytes. Additionally, DHM treatment up-regulated Jun kinase expression in liver
