BACKGROUND Metastasis is the most common cause of disease failure and mortality for non-small cell lung cancer after surgical resection. Twist has been recently identified as a putative oncogene and a key regulator of carcinoma metastasis. N-cadherin is associated with a more aggressive behavior of cell lines and tumors. The aim of this study was to(More)
Hypoxia, a common phenomenon in human solid tumors, is associated with invasion and metastasis in various tumors. Hypoxia inducible factors (HIFs) are key molecules in the hypoxic response, and regulate the activation of specific genes, which mediate many of the adaptations to hypoxia. CC chemokine receptor 7 (CCR7) has been shown to play a critical role in(More)
This study aimed to investigate the neural differentiation of human umbilical cord mesenchymal stem cells (hUCMSCs) under the induction of injured neural cells. After in vitro isolation and culture, passage 5 hUCMSCs were used for experimentation. hUCMSCs were co-cultured with normal or Aβ1-40-injured PC12 cells, PC12 cell supernatant or PC12 cell lysate in(More)
BACKGROUND Two mature microRNAs (miRNAs), hsa-miR-125a-3p and hsa-miR-125a-5p (collectively referred to as hsa-miR-125a-3p/5p), are derived from 3' and 5' ends of pre-miR-125a, respectively. Although impaired regulation of hsa-miR-125a-5p has been observed in some tumors, the role of this miRNA in invasion and metastasis remains unclear, and few studies(More)
OBJECTIVE To review published data on the biological characteristics, differentiation and applications of adipose-derived stem cells in ischemic diseases. DATA RETRIEVAL A computer-based online search of reports published from January 2005 to June 2012 related to the development of adipose-derived stem cells and their transplantation for treatment of(More)
BACKGROUND Aberrant activations of Wnt and Notch signaling pathways are individually reported to be associated with the pathogenesis of non-small-cell lung cancer (NSCLC). However, the data about the cross talk between the two signaling pathways are still limited. To elucidate potential Wnt/Notch cross talk within NSCLC, we examined the impact of Notch3(More)
BACKGROUND Aberrant regulation in the invasion of cancer cells is closely associated with their metastatic potentials. TrkB functions as a receptor tyrosine kinase and is considered to facilitate tumor metastasis. Pyk2 is a non-receptor tyrosine kinase and integrates signals in cell invasion. However, little is known about the expression of TrkB in NSCLC(More)
Studies have confirmed that TrkB plays important roles in facilitating metastasis in various types of malignant tumors. In the present study, 30 cases of colon cancer and matched non-tumors were examined for the expression of TrkB by Western blot. The expression of TrkB was also examined in 90 colon tumor sections by immunohistochemical methods, and D2-40(More)
BACKGROUND AND OBJECTIVE The positive regulatory domain proteins (PRDM) are family of transcriptional regulation related to the formation of human tumor factor and play key roles in the cell differentiation and malignant transformation. PRDM14 is a member of the PRDM family. The aim of this study is to detect the expression of PRDM14 in non-small cell lung(More)
