Myriapods play a pivotal position in the arthropod phylogenetic tree. The monophyly of Myriapoda and its internal relationships have been difficult to resolve. This study combined nearly complete 28S and 18S ribosomal RNA gene sequences (3,826 nt in total) to estimate the phylogenetic position of Myriapoda and phylogenetic relationships among four myriapod(More)
The excellent transfection efficiency and viability are essential for successful gene therapy. It suggested that when bound to its glucocorticoid receptor, glucocorticoid steroid can dilate the nuclear pore complexes and facilitated the transport of pDNA into the nucleus. In this research, the two different degrees of substitution of PAMAM-triamcinolone(More)
AIM To clone the gene of staphylococcal enterotoxin C2 and express it in the form of a soluble fusion protein in E. coli. Then the activation of SEC2 on mice lymphocyte and its lethal effects on tumor cells were studied. METHODS Staphylococcus aureus SEC2 gene was cloned into GST gene fusion vector pGEX-4T-1. The resultant plasmid pGEX-4T-SEC2 was used to(More)
OBJECTIVE To obtain recombinant fusion protein HSA (human serum albumin)-PTH(1-34) in Pichia pastoris. METHODS HSA and PTH(1-34) cDNA were obtained with PCR and the DNA segments were cloned into vector pPIC9 with linker. The linearized plasmids were transformed GS115 competent cells treated with LiCl, and mut+ transformants were screened on MD plate. With(More)
BACKGROUND Emerging evidence indicates that the interaction between glucocorticoid receptor α (GRα) and nuclear factor κB (NF-κB) is a key pathogenetic cross talk in the autoimmune and inflammatory disorders. The objective of this study was to determine the GRα expression in patients with oral lichen planus (OLP) and investigate its correlation with NF-κB(More)
The aim of this study was to establish a stable in vitro culture system for keratinocytes obtained from oral lichen planus (OLP) lesions and evaluate cultured keratinocyte characteristics including cell morphology, ultrastructure, and expression of biomarkers. OLP mucosa (histopathologically confirmed) was collected and cells isolated using the cold enzyme(More)
Uridine diphosphate glucuronosyltransferase 1A (UGT1A) is a major phase II drug-metabolism enzyme superfamily involved in the glucuronidation of endobiotics and xenobiotics in humans. Many polymorphisms in UGT1A genes are reported to inhibit or decrease UGT1A activity. In this study, two UGT1A1 allozymes, UGT1A1 wild-type and a splice mutant, as well as(More)
The complete mitochondrial genome (mitogenome) of the millipede Sphaerotheriidae sp. has been studied. The genome is 14,970 bp long and contains the typical complement of 13 protein-coding genes, 22 transfer RNA genes, and 2 ribosomal RNA genes. Gene order in Sphaerotheriidae sp. mitogenome is assumed to represent the myriapod ground pattern, which is(More)
The filtrate of Staphylococcus aureus culture has been used in an ampule form named as staphylococcal enterotoxin C injection for cancer therapy in clinic for ten years in China and proved to be effective. The active constituent of three kinds of injections is claimed to be staphylococcal enterotoxin C2 (SEC2), and the content of SEC2 is used as quality(More)
Human UDP-glucuronosyltransferases (UGTs) play a pivotal role in phase II metabolism by catalyzing the glucuronidation of endobiotics and xenobiotics. The catalytic activities of UGTs are highly impacted by both genetic polymorphisms and oligomerization. The present study aimed to assess the inter-isoform hetero-dimerization of UGT1A1, 1A9, and 2B7,(More)
