Hsa-miR-139-5p expression regulates the abundance of proteins related to poor survival cancer in CAL-62 thyroid cancer cell line


ABSTRACT: We studied the impact of hsa-miR-139-5p on the protein output by means of an iTRAQ-based approach. First, we established two CAL-62 isogenic cell lines expressing either the mature hsa-miR-139-5p or a non-targeting control upon a doxycycline inducible promoter (PTRE3G-tGFP, Dharmacon). Total proteins of P-tGFP-hsa-miR139-5p untreated or treated with doxycycline (1ug/ml) for 96 and 120 hours were isolated and labeled with iTRAQ® reagent 8-plex. Two independent experiments were performed.

It is critical to identify biomarkers and functional networks associated with aggressive thyroid cancer to anticipate disease progression and facilitate personalized patient management. We performed miRNome sequencing of 46 thyroid tumors enriched with advanced disease patients with a median follow-up of 96 months. MiRNome profiles correlated with tumor-specific histopathological and molecular features, such as stromal cell infiltration and tumor driver mutation. Differential expression analysis  ...[more]
