Cell migration plays a critical role during the development of most organisms and the process of malignant tumor metastasis. In the present study, we investigated the role of PTPIP51 (protein tyrosine phosphatase interacting protein 51) in cell motility. Overexpression of PTPIP51 induced cell elongation, increased cell migration, adhesion, and spreading,(More)
In diabetic patients complicated with colorectal cancer (CRC), metformin treatment was reported to have diverse correlation with CRC-specific mortality. In laboratory studies, metformin was reported to affect the survival of cancer stem cells (CSCs) in breast and pancreatic cancers and glioblastoma. Although cscs play a critical role in the resistance to(More)
Previous investigations have found that ebselen is able to treat neurodegenerative diseases caused by radical and acute total cerebral ischaemia. The aim of the present study was to investigate the neuroprotective effects of ebselen in a traumatic brain injury (TBI) model. Ninety Sprague-Dawley rats were randomly divided into five groups (n = 18 in each):(More)
Generating B cell-deficient mutant is the first step to produce human antibody repertoires in large animal models. In this study, we applied the clustered regularly interspaced short palindromic repeat (CRISPR)/CRISPR-associated (Cas) system to target the JH region of the pig IgM heavy chain gene which is crucial for B cell development and differentiation.(More)
Tiam1 (T lymphoma invasion and metastasis 1), a guanine nucleotide exchange factor that activates Rac, was recently identified as a novel colorectal cancer metastasis-related gene. To better understand the mechanism underlying Tiam1-mediated metastasis, we applied two-dimensional polyacrylamide gel electrophoresis (2-DE) and matrix-assisted laser desorption(More)
T lymphoma invasion and metastasis 1 (Tiam1) is a metastasis-related gene of T lymphoma that is also involved in the metastasis of a variety of other cancers. In this study, we tested the hypothesis that Tiam1 is a determinant of proliferation and metastasis in colorectal cancer, and we examined the effect of the inhibition of Tiam1 expression on(More)
An effective and versatile method for microorganism lysis and direct extraction of DNA from bioleaching bacteria was developed using pure cultures and an acid mine drainage (AMD) sediment sample. In the described method, microorganisms are treated at three different incubation temperatures: boiling water incubation for 6–10min, followed by 60 ± 5°C for(More)
Chemokine-like factor 1 (CKLF1) was the first member of the CKLF-like MARVEL transmembrane domain containing member (CMTM) family to be discovered. Its expression level is increased clearly in peripheral blood lymphocytes upon phytohemagglutinin stimulation, but little is known about the expression and function of CKLF1 in dendritic cells (DCs), which are(More)
Iron–sulfur clusters are one of the most common types of redox center in nature. Three proteins of IscS (a cysteine desulfurase), IscU (a scaffold protein) and IscA (an iron chaperon) encoded by the operon iscSUA are involved in the iron–sulfur cluster assembly in Acidithiobacillus ferrooxidans. In this study the gene of IscS from A. ferrooxidans ATCC 23270(More)
Adenosine 5′-phosphosulfate (APS) reductase is a key enzyme involved in the pathways of sulfate reduction and sulfide oxidation in the biological sulfur cycle. In this study, the gene of APS reductase from Acidithiobacillus ferrooxidans was cloned and expressed in Escherichia coli, the soluble protein was purified by one-step affinity chromatography to(More)
