Prognostic value and immunological role of MMRN1: a rising star in cancer

Abstract

BackgroundMultimerin 1 (MMRN1) is a factor V binding protein, which could support platelet adhesion and thrombus formation. In recent years, the role of MMRN1 in cancer has begun to attract attention. But systematic studies in this area are lacking. Therefore, we used bioinformatics methods to analyze MMRN1 in tumors to reveal the possible role of MMRN1. MethodsUsing the Cancer Genome Atlas (TCGA) and the Genotype-Tissue Expression (GTEx) database, we obtained relevant data for analyzing MMRN1. Using Gene Expression Pro ling Interactive Analysis (GEPIA), Human Protein Atlas (HPA), TCGA, GeneMANIA, and cBioPortal, we explored the potential role of MMRN1 in different types of tumors. Tumor Immune System Interactions and Drug Bank (TISIDB) and Sangerbox were used to analyze the correlation between MMRN1 and tumor immunity. Gene set cancer analysis (GSCA) and UALCAN were used to analyze the methylation of MMRN1. GSCA was also used to analyze the drug sensitivity of MMRN1. ResultsMMRN1 is down-regulated in most cancer types and is closely related to the prognosis of cancer patients. Interestingly, MMRN1 was found to be positively correlated with immune-related genes in most tumors. In addition, we observed different levels of methylation and mutations in different types of tumors. Drug sensitivity analysis found that MMRN1 was negatively correlated with several drugs, including GW-2580 and TL-1-85, suggesting that it can be used to develop potential anticancer therapies. ConclusionOur analysis demonstrated a signi cant relationship between MMRN1 and prognosis, tumor immunity, and drug sensitivity of several tumors. As a rising star in cancer, it needs further research.
