MicroRNA are small, non-coding, single-stranded RNAs that are estimated to regulate ~60% of the human genome. MiRNA profiling of monocyte-to-osteoclast differentiation identified miR-142-3p as a miRNA that is significantly, differentially expressed throughout osteoclastogenesis. Enforced expression of miR-142-3p via transient transfection with miR-142-3p mimic inhibited cell-to-cell contact and...

OBJECTIVE The aim of current study was to assess the association between miR-142-3p expression and the prognosis of patients with cervical cancer. PATIENTS AND METHODS Quantitative real-time polymerase chain reaction (qRT-PCR) was performed to assess the expression level of miR-142-3p in cervical cancer tissues and matched normal tissues. Then, statistical analysis was performed to determine ...

Wnt/β-catenin signaling pathway plays essential roles in mammalian development and tissue homeostasis. MicroRNAs (miRNAs) are a class of regulators involved in modulating this pathway. In this study, we screened miRNAs regulating Wnt/β-catenin signaling by using a TopFlash based luciferase reporter. Surprisingly, we found that miR-142 inhibited Wnt/β-catenin signaling, which was inconsistent wi...

MicroRNAs (miRNAs/miRs) serve an important role in the regulation of carcinogenic pathways. RCC is the most prevalent kidney cancer that occurs in adults. miRNAs have gained increasing attention due to their association with RCC tumorigenesis, serving as biomarkers for early detection and progression monitoring, and as potential targets for molecular therapy. Upregulation of miRNA-142-3p has be...

Hematopoietic-specific miR-142 is a critical regulator of various blood cell lineages including CD4 dendritic cells and platelet biogenesis in megakaryocytes. Furthermore, we recently reported that miR-142 is required in order to maintain the biconcave shape of erythrocytes, their structural resilience and lifespan, through a mechanism that involves actin filament homeostasis. Here, we used a m...

Using this approach, they identify that...

Many strategic situations in business, international relations, politics, or war are well approximated by games. A game is a multi-person decision situation, defined by its structure: the players, its “rules” (the order of players’ decisions, their feasible decisions at each point, and the information they have when making them); how players’ decisions determine the outcome; and players’ prefer...

Hematopoietic-specific microRNA-142 is a critical regulator of various blood cell lineages, but its role in erythrocytes is unexplored. Herein, we characterize the impact of microRNA-142 on erythrocyte physiology and molecular cell biology, using a mouse loss-of-function allele. We report that microRNA-142 is required for maintaining the typical erythrocyte biconcave shape and structural resili...
