SRY-related HMG-box gene 2 (SOX2) is one of the key regulatory genes that maintain the pluripotency and self-renewal properties in embryonic stem cells. Here we used immunohistochemistry to analyze the expression of SOX2 in human prostate tissues and found it contributed to tumorigenesis and correlated with histologic grade and Gleason score. We further(More)
SOX2 was reported to promote metastasis in various tumor tissues; however the underlying mechanisms remain elusive. Here, we disclosed that SOX2 improves metastasis of breast and prostate cancer cells by promoting epithelial-to-mesenchymal transition (EMT) through WNT/β-catenin, but not TGF-β or Snail1 signaling. Dual luciferase assay and chromatin(More)
Previous studies have implicated cancer stem cells in tumor recurrence and revealed that the stem cell gene SOX2 plays an important role in the tumor cell resistance to apoptosis. Nonetheless, the mechanism by which SOX2 regulates apoptosis signals remained undefined. Here, we demonstrated the surprising finding that silencing of the SOX2 gene effectively(More)
Recent studies demonstrated that cancer stem cells (CSCs) have higher tumorigenesis properties than those of differentiated cancer cells and that transcriptional factor-SOX2 plays a vital role in maintaining the unique properties of CSCs; however, the function and underlying mechanism of SOX2 in carcinogenesis of lung cancer are still elusive. This study(More)
Oncogene-induced senescence (OIS) is a tumor-suppressing response that must be disrupted for cancer to develop. Mechanistic insights into OIS have begun to emerge. Activation of the p53/p21(WAF1) and/or p16(INK4A) tumor-suppressor pathways is essential for OIS. Moreover, the DNA damage response, chromatin remodeling, and senescence-associated secretory(More)
The importance of store-operated Ca(2+) entry (SOCE) and the role of its key molecular regulators, STIM1 and ORAI1, in the development of cancer are emerging. Here, we report an unexpected dual function of SOCE in prostate cancer progression by revealing a decrease in the expression of STIM1 in human hyperplasia and tumor tissues of high histological grade(More)
BACKGROUND Recent study demonstrated the important contribution of SOX2 to tumorigenesis and metastasis properties of various types of cancers and strongly supported the concept that SOX2 can be used as an effective marker for diagnosis and predicting prognosis of cancer patients. However, our previous RNA-Seq results from human lung cancer cell line A549(More)
Transcriptional factor Sox2 promotes tumor metastasis; however its regulatory effect on tumor-associated macrophages (TAMs, M2 phenotype) has not been defined. This study disclosed concomitant expression of TAMs marker-CD163 with SOX2 in human breast cancer and showed that Sox2 in breast cancer cells promotes recruitment of TAMs with altered expression of(More)
Tip60 is a multifunctional acetyltransferase involved in multiple cellular functions. Acetylation of p53 at K120 by Tip60 promotes p53-mediated apoptosis after DNA damage. We previous showed that Tip60 activity is induced by phosphorylation at T158 by p38. In this study, we investigated the role of p38-mediated Tip60 phosphorylation in p53-mediated, DNA(More)
A sort of intelligent protection system for conveyor belt was designed, which mainly aimed at the phenomenon of belt slipped, belt broken, overloaded and coupling broken etc. It was designed by using intelligent instrument, monitoring software and fault detection technology, furthermore, the software and hardware were described. The protection system can(More)
