| Abstract | Purpose:It has been shown that circular RNA (circRNA) is a key regulatory factor in development and progression of human tumors. However, the working mechanism and clinical significance of most circRNAs remain unknown in human cancer, including multiple myeloma (MM), a hematologic malignancy. Patients and methods:In the present study, high-throughput circRNA microarray was combined with bioinformatics to identify differentially expressed circRNAs in MM. The hsa_circ_0007841 expressions were shown in MM tissues of 86 patients and drug-resistant cell lines and pathological features were detected. Further, the relationship between hsa_circ_0007841 expressions in the MM tissues and pathological features of MM patients were discussed. The role of hsa_circ_0007841 as a potential biomarker and therapeutic target was analyzed. Results:Our results indicated that in MM tissues collected from patients, MM cell lines and drug-resistant cell lines, the hsa_circ_0007841 expression was significantly upregulated. A close connection with prognosis was observed. That is, hsa_circ_0007841 upregulation was correlated with chromosomal aberrations, such as gain 1q21, t(4:14) and mutations in ATR and IRF4 genes. This finding was further verified in large samples. Finally, bioinformatics analysis indicated interaction that 8 differentially expressed miRNAs and 10 candidate mRNAs interacted with hsa_circ_0007841. These results sheds new light on the basic functional research in the future. Conclusion:It was reported for the first time that hsa_circ_0007841 was significantly upregulated in MM. Our study indicated that hsa_circ_0007841 may be a novel biomarker for MM and involved in the progression of MM. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
