This study aimed to investigate the effect of miR-122-5p on the differentiation of human induced pluripotent stem cells (hiPSCs) into hepatocyte-like cells and its impact on the EMT process in liver cancer cells.

Clinical Peptidomics: Advances in Instrumentation, Analyses, and Applications.

Extensive effort has been devoted to the discovery, development, and validation of biomarkers for early disease diagnosis and prognosis as well as rapid evaluation of the response to therapeutic interventions. Genomic and transcriptomic profiling are well-established means to identify disease-associated biomarkers. However, analysis of disease-associated peptidomes can also identify novel peptide biomarkers or signatures that provide sensitive and specific diagnostic and prognostic information for specific malignant, chronic, and infectious diseases.
