Androgen receptor (AR) plays a pivotal role in prostate cancer, primarily by regulating different gene expression programs elicited by androgen, which is important for cancer cell proliferation, survival, and differentiation. It is believed that the transcriptional function of AR is mediated largely by distinct nuclear coregulators. We report here the(More)
KCNJ2/Kir2.1, a member of the classical inwardly rectifying potassium channel family, is commonly expressed in a wide range of tissues and cell types. Previous studies indicated that Kir2.1 may be associated with SCLC multidrug resistance (MDR). However, whether Kir2.1 can regulate MDR and its underlying mechanisms remain poorly understood in SCLC.(More)
MicroRNAs (miRNAs) are now known to play important roles in the regulation of gene expression for developmental timing, cell proliferation and apoptosis. Therefore, it is likely that they also modulate sensitivity and resistance to anti-cancer drugs. To better understand the molecular mechanisms of multidrug resistance in SCLC and identify novel molecular(More)
MicroRNAs (miRNAs) represent an abundant group of small non-coding RNAs that regulate gene expression, and have been demonstrated to play roles as tumor suppressor genes (oncogenes), and affect homeostatic processes such as development, cell proliferation, and cell death. Subsequently, epidermal growth factor-like domain 7 (EGFL7), which is confirmed to be(More)
Etk/Bmx is a cytoplasmic tyrosine kinase, which was first identified in human bone marrow cells. It has been found to play an important role in the regulation of differentiation and tumorigenicity in some cancers. The aim of this study was to investigate the significance of Etk/Bmx expression in hepatocellular carcinoma (HCC) and the relationship between(More)
To investigate the role of N-acetylglucosaminyltransferases V (GnT-V) in the malignancy of human hepatocellular carcinoma (HCC), the GnT-V stably suppressed cell line HepG2 GnT-V/1564 was constructed from HepG2. The proliferation, migration, invasion, metastasis of HepG2 GnT-V/1564 was investigated both in vitro and in vivo. The clinical pathological(More)
To study the role of c-Jun N-terminal kinase (JNK) and its relation to transcription factor AP-1 and Jun family proteins in hepatocellular carcinoma (HCC) with or without hepatitis B virus (HBV) infection. Immunohistochemical and in situ hybridization techniques were performed for studying phosphorylated JNK (p-JNK), c-Jun, JunB, JunD and AP-1 in 40 cases(More)
PRO2000/ANCCA may be an important candidate gene which located within a region of chromosome 8q in hepatocellular carcinoma (HCC). However, its significance remains unclear. The aim of this study was to explore the clinical significance of PRO2000/ANCCA expression in HCC. The correlations of PRO2000/ANCCA expression with clinicopathological factors and(More)
Constitutive NF-κB activation by proinflammatory cytokines plays a major role in cancer progression. However, the underlying mechanism is still unclear. We report here that histone methyltransferase NSD2 (also known as MMSET or WHSC1), a target of bromodomain protein ANCCA/ATAD2, acts as a strong coactivator of NF-κB by directly interacting with NF-κB for(More)
MicroRNAs (miRNAs) - short non-coding RNA molecules - post-transcriptionally regulate gene expressions and play crucial roles in diverse biological processes such as development, differentiation, apoptosis and proliferation. In order to investigate the possible role of miRNAs in the development of multi-drug resistance (MDR) in human glioblastoma, we first(More)
