Study on single nucleotide polymorphisms of macrophage scavenger receptor 1 gene in xanthelasma palpebrarum patients / 国际眼科杂志(Guoji Yanke Zazhi)

@#AIM: To study the single nucleotide polymorphisms(SNPs)of Macrophage Scavenger Receptor 1(MSR1)gene in xanthelasma palpebrarum patients.<p>METHODS: We drew peripheral venous blood from 20 xanthelasma palpebrarum patients and 20 healthy participants. We detected the SNPs of MSR1 gene with Sanger sequencing, examined serum lipids and α-lipoprotein of the patients, and scanned carotid arteries of the patients with color ultrasound. After that, we kept on observation of the participants.<p>RESULTS: There was no significant difference in the SNPs of MSR1 genotype between xanthelasma palpebrarum patients and healthy participants. However, in some patients with carotid atherosclerosis and hyperlipidemia, there were homozygous mutations at S2-SNP1, S5-SNP2 and S5-SNP4 in the exon region of MSR1 gene, which were related to atherosclerosis.<p>CONCLUSION: Xanthelasma palpebrarum is related to SNPs of MSR1 in atherosclerosis.

Effects of miR-34 on migration and invasion of prostate cancer cells by MSR1 protein / 中国免疫学杂志

Objective:To investigate the effect of miR-34a on the migration and invasion of prostatic cell line through MSR1.Methods:Western blot was used to detect the expression of MSR1 in prostate cancer cell lines.qPCR was used to detect the ex-pression of miR-34a in prostate cancer cell lines.The correlation between miR-34a and MSR1 was examined by double luciferase as-say.Transwell invasion assay was used to detect the effect of miR-34a and MSR1 on the invasion ability of prostate cancer cells.The effects of miR-34a and MSR1 on the fine migration ability of prostate cancer were examined by scratch healing.Results:The expression level of MSR1 in PC3 cells was relatively high by Western blot.The expression level of miR-34a in PC3 cells was relatively low by qPCR.Double luciferase assay showed a direct binding site between miR-34a and MSR1,MiR-34a could regulate the expression level of MSR1,Scaffold Healing Test and Transwell Invasion Test were used to detect the migration and invasion of PC3 cells after overexpressing miR-34a.Overexpression of MSR1 could reverse the inhibitory effect of miR-34a on the migration and invasion of PC3 cells.Conclusion:miR-34a can regulate the migration and invasion of prostate cancer cells through MSR1 protein.
