Brief summary: Lymphomas are hematological malignancies, which are divided into non-Hodgkin lymphoma and Hodgkin lymphoma. Non hodgkin lymphoma is a lymphoma-derived malignancy that makes up about 90% of all malignant lymphoma. According to its origin, non hodgkin lymphoma is classified into B-cell non hodgkin lymphoma and T-cell non hodgkin lymphoma. The most common types are follicular lymphoma, and diffuse large B-cell lymphoma. Lymphomas are types of cancer that develops from lymphocytes, a type of white blood cell. Diagnosis is by examination of a bone marrow or lymph node biopsy. Non hodgkin lymphoma mortality has increased in recent years and has become the seventh most frequently occurring cancer.

Detailed description: Biomarkers are defined as objective indicators of biological processes, pathogenic processes, or pharmacological response to a therapeutic intervention. Diagnostic biomarkers which are type of biomarkers, identify the presence of disease, differentiate normal from malignant, distinguish different diagnoses or progression stages.

Micro ribosomal nucleic acids have been demonstrated to possess biomarker potentiality in multiple diseases, both individually and when combined in signature profiles. Micro ribosomal nucleic acids are short single-stranded noncoding ribosomal nucleic acids of 20-22 nucleotides that function to regulate gene expression at the posttranscriptional level. They play fundamental roles in the regulation of cellular proliferation, differentiation, and apoptosis. Dysregulation of micro ribosomal nucleic acid is a unique feature of cancers including lymphomas . Information about the functional role of micro ribosomal nucleic acid dysregulation in lymphomas is increasing day by day.

The present study focuses on the micro ribosomal nucleic acid 155 since this molecule represents a typical multifunctional micro ribosomal nucleic acid. To date, increased evidence points out that micro ribosomal nucleic acid 155 is involved in numerous biological processes including haematopoiesis, inflammation and immunity. Deregulation of micro ribosomal nucleic acid 155 has been found to be associated with different kinds of cancer, cardiovascular diseases and viral infections. Since investigation on the functional activity of micro ribosomal nucleic acid 155 started a few years ago, it is reasonable to predict that many other functions will be uncovered in the near future.

Micro ribosomal nucleic acid 155 maps within and is processed from an exon of a noncoding ribosomal nucleic acid transcribed from the B-cell Integration Cluster located on chromosome 21.

Micro ribosomal nucleic acid 155 is an oncological micro ribosomal nucleic acid with a crucial role in tumor initiation and development of several B-cell malignancies. Micro ribosomal nucleic acid 155 was upregulated in several malignancies compared to nonmalignant controls and overexpression of micro ribosomal nucleic acid 155 was further associated with poor prognosis. Elevated expression of micro ribosomal nucleic acid 155 shows potentiality as a diagnostic and prognostic biomarker in diffuse large B-cell lymphoma and chronic lymphocytic leukemia. Additionally, in vitro and in vivo studies suggest micro ribosomal nucleic acid 155 as an efficient therapeutic target, supporting its oncogenic function. The use of inhibiting anti-micro ribosomal nucleic acid structures indicates promising potential as novel anticancer therapeutics.

The search for non-invasive tools for the diagnosis and management of cancer has long been a goal of cancer research that has led to great interest in the field of circulating nucleic acids in plasma and serum.
