Effect of Lifei Xiaoji Pill (理肺消积丸) on the Warburg Effect and USP47/BACH1 Pathway in Tumor Tissues of Lung Cancer Model Mice
(理肺消积丸, LXP) in the treatment of non small cell lung cancer based on the Warburg effect and the USP47/BACH1 pathway.
Methods
2
Fifty C57BL/6 mice were randomly divided into five groups, model group, LXP group, inhibitor group, LXP + inhibitor group, and cisplatin group, with 10 mice in each group. A lung cancer mouse model was established by subcutaneously injecting Lewis cells. On the next day, the model group mice were given 0.2 ml of saline by gavage daily, the LXP group given 240 mg/(kg·d) of LXP solution once a day by gavage, the inhibitor group intraperitoneally injected with P22077 at a dose of 10 mg/(kg·d) every day, the LXP + inhibitor group given both LXP by gavage and P22077 by intraperitoneal injection once a day, and the cisplatin group received 0.5 mg/(kg·d) cisplatin intraperitoneally every other day. All treatments lasted for 14 days. On the day after the last dose, tumor weight and volume were measured, tumor histopathology was examined by HE staining, apoptosis in tumor tissues was detected by TUNEL staining, and proliferation cell nuclear antigen (PCNA) protein levels were detected by immunohistochemistry. Warburg effect indicators, including glucose concentration, lactate content, and adenosine triphosphate (ATP) production in tumor tissues, were measured. Western Blot and qRT-PCR were used to detect the protein and mRNA expression levels of USP47, BACH1, hexokinase 2 (HK2), and glyceraldehyde 3-phosphate dehydrogenase (GAPDH).
Results
2
Compared with the model group, all drug intervention groups showed reduced tumor weight and volume, improved tumor pathology, decreased PCNA positive rate, increased apoptosis rate, and reduced expression levels of USP47, BACH1, and HK2 proteins and mRNA (
P
<0.05 or
P
<0.01). Except for lactate content in the cisplatin group, the glucose concentration in tumor tissues of other drug intervention groups increased, while lactate content and ATP production decreased (
P
<0.05 or
P
<0.01). Compared with the LXP group, the LXP + inhibitor group showed more significant improvements in these indicators (
P
<0.05 or
P
<0.01). Compared with the cisplatin group, the LXP + inhibitor group had lower mRNA expression of HK2 and GAPDH, and lower protein levels of USP47 and HK2 (
P
<0.05 or
P
<0.01). Co
mpared with the inhibitor group, the cisplatin group had higher HK2 protein levels, while the LXP + inhibitor group showed lower mRNA expression of BACH1, HK2, and GAPDH (
P
<0.05 or
P
<0.01).
Conclusion
2
LXP significantly inhibits tumor growth in lung cancer mice, and its mechanism of action may be related to inhibiting the Warburg effect via the USP47/BACH1 pathway.
