BACKGROUND Polycythemia vera is a clonal hematopoietic stem cell disorder in which the JAK2 V617F mutation is observed in >95% of patients, but an as yet unidentified process appears to initiate the clonal expansion of hematopoiesis. Because microRNA regulate hematopoietic differentiation, we hypothesized that dysregulated expression of microRNA may contribute to the pathophysiology of polycyth...

Glioblastomas (GBM), the most common and aggressive type of malignant glioma, are characterized by increased invasion into the surrounding brain tissues. Despite intensive therapeutic strategies, the median survival of GBM patients has remained dismal over the last decades. In this study we examined the expression of miR-145 in glial tumors and its function in glioma cells. Using TCGA analysis ...

literature regarding the role of mir-143/145 in tumor initiation/progression. Herein, we aim to contribute our experience and observations to this ongoing debate. We will start from the experimental data presented in the outstanding work of the Tyler Jacks lab, by Dimitrova, Gocheva and colleagues [6]. They show, in a kRAS/p53 murine model of lung adenocarcinoma, that the contribution of the mi...

Stomach adenocarcinoma (STAD) is one of the leading causes of cancer morbidity and mortality worldwide. The present study aimed to identify the microRNAs associated with STAD survival time. The clinical information and microarray miRNA and mRNA expression profiles of STAD patients were downloaded from The Cancer Genome Atlas. Differential expression (DE) analysis was performed to identify DEmiR...

microRNAs (miRNAs) play a crucial role in tissue development and the pathology of various diseases. However, the effects and roles of miRNAs in macrophage polarization have yet to be investigated. In this study, we analyzed and compared the miRNA expression profiles of bone marrow-derived macrophages (BMDMs) with two distinct polarizing conditions (classical macrophage activation 'M1' and alter...

Our previous long noncoding RNA (lncRNA) microarray revealed that lncRNA-TCONS_00026907 is aberrantly expressed between cervical cancer tissues and adjacent tissues. This study aims to explore the potential role of TCONS_00026907 in the development of cervical cancer. The expression levels of TCONS_00026907 in cervical cancer tissues and adjacent tissues from 83 patients of cervical cancer were...

Esophageal squamous cell carcinoma (ESCC) in humans is a deadly disease associated with dietary zinc (Zn)-deficiency. In the rat esophagus, Zn-deficiency induces cell proliferation, alters mRNA and microRNA gene expression, and promotes ESCC. We investigated whether Zn-deficiency alters cell metabolism by evaluating metabolomic profiles of esophageal epithelia from Zn-deficient and replenished ...
