Studies of polymorphisms in CYP1A1, CYP2E1, CYP2D6, and GSTM1 and their relationship to lung cancer susceptibility and chemotherapy response have been reported, but the results are not consistent. In this study we selected four polymorphisms in these genes, several of which have previously been researched, and investigated their association with lung cancer(More)
This paper presents a microfluidic system enabling cell type classification based on continuous characterization of size-independent electrical properties (e.g., specific membrane capacitance (C(specific membrane)) and cytoplasm conductivity (σ(cytoplasm)). In this study, cells were aspirated continuously through a constriction channel, while cell(More)
Single-cell electrical phenotyping (e.g., specific membrane capacitance (Cm) and cytoplasm conductivity (σp)) has long been regarded as potential label-free biophysical markers in tumor status evaluation. However, previous studies only reported the differentiation of tumor cell lines without classifying real tumor samples using cellular electrical(More)
Cyclophilin A (CypA) is a cytosolic protein possessing peptidyl-prolyl isomerase activity that was recently reported to be overexpressed in several cancers. Here, we explored the biology and molecular mechanism of CypA in non-small cell lung cancer (NSCLC). The expression of CypA in human NSCLC cell lines was detected by real-time reverse transcription PCR.(More)
Zinc finger protein, X-linked (ZFX) is a transcription factor encoded by its gene on the mammalian X chromosome, and functions to control survival and activity of stem cells and lymphocytes. However, little is known about the role of ZFX in tumorigenesis. The function of ZFX in cell proliferation was investigated by the lentivirus-mediated short hairpin RNA(More)
BACKGROUND The transcription factor PAX6 is primarily expressed in embryos. PAX6 is also expressed in several tumors and plays an oncogenic role. However, little is known about the role of PAX6 in lung cancer. METHODS The function of PAX6 in lung cancer cells was evaluated by small interfering RNA-mediated depletion of the protein followed by analyses of(More)
PURPOSE PIK3CA gene mutations have been detected in many malignancies, but the frequency of different mutations and their role in the carcinogenesis of lung adenocarcinoma are still unclear. The purpose of this study was to explore the clinical pathological impact and prognostic implications of PIK3CA mutations in lung adenocarcinoma. METHODS Five common(More)
OBJECTIVES Fascin, a conserved actin bundling protein family member, is frequently up-regulated in various cancer types, including non-small-cell lung cancer (NSCLC), and it plays increasingly important roles in the progression of tumor invasion and metastasis. However, variations in the serum fascin level in tumor patients are usually neglected. (More)
BACKGROUND Multidrug resistance protein 4 (MRP4), also known as ATP-cassette binding protein 4 (ABCC4), is a member of the MRP/ABCC subfamily of ATP-binding cassette transporters, which are capable of pumping a wide variety of drugs out of the cell. However, little is known about the function of ABCC4 in the proliferation of lung cancer cells. METHODS(More)
To detect the expression of mammalian target of rapamycin (mTOR) and PTEN in non-small cell lung cancer (NSCLC), and explore their role in the prognosis of patients with NSCLC. Samples of cancer tissues and normal lung tissues from 78 patients with NSCLC were examined for expression of mTOR and PTEN by real-time polymerase chain reaction and(More)
