CUL4A has been proposed as oncogene in several types of human cancer, but its clinical significance and functional role in human non-small cell lung cancer (NSCLC) remain unclear. Expression level of CUL4A was examined by RT-PCR and Western blot. Forced expression of CUL4A was mediated by retroviruses, and CUL4A silencing by shRNAs expressing lentiviruses.(More)
CUL4A encodes a core component of a cullin-based E3 ubiquitin ligase complex that regulates many critical processes such as cell cycle progression, DNA replication, DNA repair and chromatin remodeling by targeting a variety of proteins for ubiquitination and degradation. In the research described in this report we aimed to clarify whether CUL4A participates(More)
This paper presents the position control of a DC servo motor using PID Control algorithms. PID controllers are designed based on labview program, and the real - time position control of the DC servo motor was realized by using DAQ device. All codes are developed on The LabVIEW Real-Time Development System and then download applications to run on PXI-8196(More)
Car License Plate Recognition (CLPR) is the key technology of the achievement of intelligent transport system, and vehicle license plate location plays a very important part in the whole Recognition system. The article presents an effective method based on wavelet transform to locate the vehicle license plate. Firstly, the general profile of Car License(More)
BACKGROUND NKX3.1 and PCAN1 are both prostate-specific genes related to prostate development and prostate cancer. So far, little is known about the regulatory mechanisms of the expression of these two genes. In the present study, we found that NKX3.1 upregulated PCAN1 gene transcription in LNCaP prostate cancer cells. To understand the regulatory(More)
BACKGROUND Bovine viral diarrhea virus (BVDV) infections continue to cause significantly losses in the deer population. Better isolation and identification of BVDV from sika deer may contribute significantly to the development of prophylactic therapeutic, and diagnostic reagents as well as help in prevention and control of BVDV. However, isolation and(More)
Amplification of chromosome 20q is frequently found in various types of human cancers, including breast cancer. The list of candidate oncogenes in 20q has expanded over the past decade. Here, we investigate whether FAM83D (family with sequence similarity 83, member D) on chromosome 20q plays any role in breast cancer development. The expression level of(More)
Ubiquitin specific protease 35 (USP35) is a member of deubiquitylases (DUBs). It remains largely unknown about the biological role and the regulation mechanism of USP35. Here, we first identified miR let-7a as a positive regulator of USP35 expression and showed that USP35 expression positively correlates with miR let-7a expression in different cancer cell(More)
AIMS We aim to investigate the relationship between 1,25-(OH)2VD3 and hsa-let-7a in lung cancer A549 cells. METHODS Real-time PCR and luciferase reporter assays were used to detect the influence of 1,25-(OH)2VD3 on the expression of hsa-let-7a-2 after A549 cells were treated with 1,25-(OH)2VD3 (10(-8)~10(-6)mol/L). Analysis of the 5.0Kb upstream sequence(More)
CyclinD1 over-expression is the key pathogenetic event underlying airway smooth muscle (ASM) proliferation. Human antigen R (HuR) is a ubiquitously expressed RNA-binding protein, and is known to regulate the expression of multiple cell cycle regulators. The aim of the study is to investigate whether HuR might also be involved in ASM proliferation. In(More)
