Epithelial-mesenchymal transition (EMT), a key step in the early stages of cancer metastasis, is orchestrated by several signaling pathways, including IL-6/JAK/STAT3 and TGF-β/Smad signaling. However, an association between the two signaling pathways during the EMT process is largely unknown. Here, we focused on lung cancer and demonstrated that TGF-β1(More)
Hashimoto's thyroiditis (HT) has long been epidemiologically associated with excess iodine levels. However, the underlying immunological mechanisms still remain largely unexplored. Th17 cells are commonly recognized as playing vital roles in various autoimmune diseases. Here we show that intra-thyroid infiltrating Th17 cells and serum IL-17 levels were(More)
OBJECTIVE To evaluate the risk factors of central lymph node metastasis of papillary thyroid microcarcinoma. METHOD Published articles about papillary thyroid microcarcinoma were searched in PubMed, MEDLINE and EMBASE until October 2013 to examine the risky factors of central lymph node metastasis. Software RevMan 5.0 was used for meta-analysis. RESULTS(More)
BACKGROUND Genome-wide association studies have reported that a polymorphism near the estrogen receptor gene (ESR1) (rs2046210) is associated with a risk of breast cancer, with the A allele conferring an increased risk. However, considering the controversial results from more recent replicated studies, we conducted a case-control study in an independent(More)
TGFβR1 plays an important role in TGF-β signaling transduction and serves as a tumor suppressor. Our previous studies show that reduced expression of TGFβR1 is common in non-small cell lung cancer (NSCLC) and TGFβR1 variants confer risk of NSCLC. However, the epigenetic mechanisms underlying the role of TGFβR1 in NSCLC carcinogenesis are still elusive. We(More)
OBJECTIVES Epithelial-mesenchymal transition (EMT) is a key process in early stage of cancer metastasis. TGF-β-mediated EMT is characterized by repression of E-cadherin and induction of N-cadherin (CDH2) in various cancers. Although many investigations have focused on the regulation of E-cadherin expression, the transcription-mediated events that directly(More)
In human cancers, dysregulated expression of LIM-homeobox gene 2 (LHX2) and downregulation of miR-1238 has been reported separately. However, the relationship between them remains unclear. We investigated the functional contribution of miR-1238 to the regulation of LHX2 in non-small cell lung cancer (NSCLC). Here, computational algorithms predicted that the(More)
BACKGROUND AND OBJECTIVE TIF1γ (transcription intermediary factor 1 gamma), which belongs to transcription intermediary factor 1 family, is an inhibitor of the TGF-β/Smad signaling pathway and could inhibit the signal transduction mediated by TGF-β. The deficiency of TIF1γ expression in a variety of tumor cells suggests that TIF1γ may play as a tumor(More)
Epithelial-mesenchymal transition (EMT) is a key event in cancer metastasis, which confers cancer cells with increased motility and invasiveness, and EMT is characterized by loss of epithelial marker E-cadherin and gain of mesenchymal marker N-cadherin. Transforming growth factor-β (TGF-β) signaling is a crucial inducer of EMT in various types of cancer.(More)
Anatase TiO(2) nanobelts with 13 nm in thickness have been successfully synthesized via an epitaxial growth chemical transformation, in which the primary H(2)Ti(3)O(7) nanobelt frameworks can be preserved. The phases, crystal structures, morphologies, and growth behavior of both the precursory (Na(2)Ti(3)O(7) and H(2)Ti(3)O(7)) and resultant products(More)
