Abstract:
Benzene is an established human hematotoxicant and leukemogen. New insights into the pathogenesis of benzene hematotoxicity are urgently needed. Long non-coding RNA (lncRNA) widely participate in various physiological and pathological processes. It has been shown that lncRNA plays an important role in hematologic malignancy tumorigenesis. However, the expression and biological function of lncRNA during benzene hematotoxicity progress remain largely unknown. An integrated analysis of differentially expressed lncRNA and mRNA was performed to identify genes which were likely to be critical for benzene hematotoxicity through Microarray analysis. Dynamic gene network analysis of the differentially expressed lncRNA and mRNA was constructed and two main lncRNA (NR_045623 and NR_028291) were discovered and two key lncRNA subnets were involved in immune responses, hematopoiesis, B cell receptor signaling pathway and chronic myeloid leukemia. These findings suggested that NR_045623 and NR_028291 might be the key genes associated with benzene hematotoxicity.

01:23Types of RNA
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in the regulation of gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.

01:31Translation
Translation is the process of synthesizing proteins from the genetic information carried by messenger RNA (mRNA). Following transcription, it constitutes the final step in the expression of genes. This process is carried out by ribosomes, complexes of protein and specialized RNA molecules. Ribosomes, transfer RNA (tRNA), and other proteins produce a chain of amino acids—the polypeptide—as the end product of translation.
