Correlation between serum miR-375 and CHSY1 expression and helicobacter pylori infection in gastric cancer
To investigate the correlation between serum miR-375 and chondroitin sulfate synthase 1 (CHSY1) expression levels and helicobacter pylori (Hp) infection in gastric cancer.
Methods
2
A total of 96 patients with gastric cancer admitted to our hospital from June 2018 to June 2021 were selected as the gastric cancer group, and 68 patients with chronic superficial gastritis admitted to our hospital during the same period were selected as the control group. The
13
C breath test was performed to detect the Hp infection. According to the Hp infection density, patients were divided into the Hp mild group (25 cases), the Hp moderate group (30 cases), and the Hp severe group (26 cases). The expression levels of miR-375 and CHSY1 mRNA in serum were determined by qPT-PCR.
Spearman
correlation was applied to analyze the correlation between the expression levels of miR-375 and CHSY1 in serum and Hp infection in patients with gastric cancer.
Results
2
Compared with the control group, the positive rate of Hp infection in the gastric cancer group was significantly higher (
P
<
0.05), the expression levels of miR-375 in serum of HP-negative and HP-positive patients were significantly decreased (
P
<
0.05), and the expression levels of CHSY1 mRNA were significantly increased (
P
<
0.05). The expression levels of miR-375 in serum of Hp-positive patients in the gastric cancer group and the control group were lower than that of Hp-negative patients (
P
<
0.05), and the expression levels of CHSY1 mRNA were higher than that of Hp-negative patients (
P
<
0.05). With the increase of the degree of Hp infection, the expression level of miR-375 decreased and the expression level of CHSY1 mRNA increased (
P
<
0.05). The results of
Spearman
correlation analysis showed that the expression level of miR-375 in serum was negatively correlated with Hp infection in patients with gastric cancer (
r
=-0.648,
P
<
0.001), and the expression level of CHSY1 mRNA was positively correlated with Hp infection in patients with gastric cancer (
r
=0.534,
P
<
0.001).
Conclusion
2
The expression level of miR-375 in serum of patients with gastric cancer decreases, and the expression level of CHSY increases, both of which are closely related to Hp infection.
