High-density cell culture is pivotal for the chondrogenic differentiation of human mesenchymal stem cells (hMSCs). Two high-density cell culture systems, micromass and pellet culture, have been used to induce chondrogenic differentiation of hMSCs. In micromass culture, the induced-cartilage tissues were larger, more homogenous and enriched in(More)
Adipogenesis and osteogenesis, a reciprocal relationship in bone marrow, are complex processes including proliferation of precursor cells, commitment to the specific lineage, and terminal differentiation. Accumulating evidence from in vitro and in vivo studies suggests that melatonin affects terminal differentiation of osteoblasts and adipocytes, but little(More)
The genetic variations in NBS1 gene have been reported to be associated with cancer risk. The polymorphisms in 3'-untranslated region (3'-UTR) of NBS1 might affect gene's function and thus contribute to cancer susceptibility. We hypothesized that these polymorphisms of NBS1 are associated with the lung cancer risk. In two independent case-control studies(More)
Aberrant tumor cell B7-H1 expression, a member of B7 family that can predominantly stimulate interleukin 10 (IL-10) products, contributed to the tumor immune evasion and tumor progression. This study was designed to investigate the expression of B7-H1 and IL-10 in normal pancreas tissues and pancreatic carcinoma samples, and to evaluate clinical(More)
BACKGROUND Adolescent idiopathic scoliosis (AIS) is one of the most common spinal deformities found in adolescent populations. Recently, a genome-wide association study (GWAS) in a Japanese population indicated that three single nucleotide polymorphisms (SNPs), rs11190870, rs625039 and rs11598564, all located near the LBX1 gene, may be associated with AIS(More)
Signal-induced proliferation associated gene 1 (Sipa1) is a signal transducer to activate the Ras-related proteins and modulate cell progression, differentiation, adhesion and cancer metastasis. In this study, we tested the hypothesis that single nucleotide polymorphisms (SNPs) in Sipa1 are associated with lung cancer risk and metastasis. Three common SNPs(More)
Accumulating evidences indicate that microRNAs play a vital role in regulating tumor progression. However, the roles of miR-148b in hepatocellular carcinoma (HCC) are still largely unknown. In this study, our data showed that miR-148b was significantly downregulated in 40 pairs of human HCC tissues. Further, the deregulated miR-148b was significantly(More)
PURPOSE The clinical significance of MYCN expression in children with neuroblastoma (NB) remains controversial. To determine the prognostic significance of MYCN expression in the absence of MYCN amplification, we analyzed MYCN mRNA and protein expression in tumors from 69 patients. PATIENTS AND METHODS Sixty-nine NB tumor samples with nonamplified MYCN(More)
Neuroblastomas are biologically heterogeneous tumors that consist of two main cell populations: neuroblastic/ganglionic cells and Schwann cells. The amount of Schwannian stroma strongly impacts prognosis, and favorable outcome is associated with tumors that are Schwannian stroma rich/stroma dominant. At the present time, there is controversy regarding the(More)
OBJECTIVE To identify the genetic abnormality responsible for osteoarthritis (OA), avascular necrosis (AVN) of the femoral head, and Legg-Calvé-Perthes disease in a single family, and to determine factors responsible for the distinct phenotypes manifested by different family members. METHODS Forty-two members of a 5-generation family were recruited and(More)
