Low expression of LPA1 inhibits tumorigenic ability of ovarian cancer in nude mice. a Volume of mice tumor. b Weight of mice tumor. c RT-qPCR detection results of mRNA levels of related factors in tumor tissues. d Western blot analysis of the protein levels of related factors in tumor tissues. e Statistical graph of protein levels of related factors. f Immunohistochemistry for detecting CD34 expression (200×). Measurement data were expressed as mean ± standard deviation. Data in compliance with normal distribution and homogeneity between two groups were compared using t test. Comparisons among multiple groups were conducted by one-way ANOVA followed by Tukey’s post hoc test. Statistics of tumor volume at different time points was analyzed using repeated measures ANOVA. *p < 0.05 vs. normal tissues or cells. The experiment was repeated three times independently
