Osteoclasts secrete factors that may promote mesenchymal stem cell mineralization in vitro. Fibroblasts are the most common cells in connective tissue and are involved in the process of exotic ossification in many diseases such as ankylosing spondylitis. The purpose of this study was to investigate whether osteoclast-like cells would induce the osteogenic differentiation of fibroblasts in vitro...

BACKGROUND Oral leukoplakia (OLK) is a potentially malignant disorder of the oral cavity. However, the underlying mechanism of OLK is still unclear. In this study, we explore possible miRNAs involved in OLK. METHODOLOGY/PRINCIPAL FINDINGS Using miRNA microarrays, we profiled miRNA expression in OLK and malignantly transformed OLK (mtOLK) tissue samples. The upregulation of miR-31*, miR-142-5p...

BACKGROUND Therapeutic management of Locally Advanced Rectal Cancer (LARC) involves pre-operative chemoradiotherapy (pCRT) followed by surgery. However, after pCRT the complete pathological response is approximately 20%, whereas in 20 to 40% of patients the response is poor or absent. METHODS Cancer biopsy specimens (n= 38) and serum samples (n= 34) obtained before pCRT from 38 LARC patients ...

BACKGROUND Novel therapies tailored to the molecular composition of esophageal squamous cell carcinoma (ESCC) are needed to improve patient survival. We investigated the regulatory network of long intergenic non-protein coding RNA, regulator of reprogramming (linc-ROR) and sex-determining region Y-box 9 (SOX9), and their therapeutic relevance in ESCC. METHODS Linc-ROR and SOX9 expression were...

Aplysia VAP-33 (VAMP-associated protein) has been previously proposed to be involved in the control of neurotransmitter release. Here, we show that a Drosophila homolog of VAP-33, DVAP-33A, is localized to neuromuscular junctions. Loss of DVAP-33A causes a severe decrease in the number of boutons and a corresponding increase in bouton size. Conversely, presynaptic overexpression of DVAP-33A ind...
