Two full-length cDNAs (TCH1 and TCH2) were obtained from a cDNA library of Taxus chinensis mainly by the single specific-primer PCR (SSP-PCR) method. Compared with other reported enzymes from Taxus species, the deduced amino acid sequences of TCH1 and TCH2 exhibit significant homologies to hydroxylases that are involved in taxol biosynthesis. These findings imply that the two new genes are clos...

Background and Aim: Major Histocompatibility Complex (MHC) is the most polymorphic system in the genome of different species. In human beings, it named human leukocyte antigen (HLA). The association between genetics, particularly the genes of the MHC and many Infection diseases especially viral infection has been known. The aim of this study is survey of association of HLA-B*51 and -B*52 allele...

Thesis Abstract Several cytokines are known to be involved in the pathogenesis of non-Hodgkin Lymphomas (NHL). Given importance understanding genetic predisposition NHL, this work was designed study impact IL-10 (-1082 G/A; rs1800896 and -819 C/T; rs1800871), IL-6 (-174 G/C; rs1800795) CD38 (184C/G; rs6449182) gene polymorphisms on susceptibility Egyptians NHL. Both loci IL10 were genotyped usi...

BACKGROUND Molecular testing is more precise compared to serology and has been widely used in genotyping blood group antigens. Single nucleotide polymorphisms (SNPs) of blood group antigens can be determined by the polymerase chain reaction with sequence specific priming (PCR-SSP) assay. Commercial high-throughput platforms can be expensive and are not approved in China. The genotype frequencie...

BACKGROUND The SMIM1 protein carries the Vel blood group antigen, and homozygosity for a 17 bp deletion in the coding region of the SMIM1 gene represents the molecular basis of the Vel- blood group phenotype. We developed PCR-based methods for typing the SMIM1 17 bp (64-80del) gene deletion and performed a molecular screening for the Vel- blood type in German blood donors. METHODS For SMIM1 g...

Background. Microlymphocytotoxicity (MLCT) and flowcytometry (FC) are the conventional serological methods to detect HLA-B* 27. Due to some disadvantages in these methods, most of the HLA laboratories have now switched over to molecular methods. Molecular techniques based on commercial kits are expensive; as such many laboratories with limited funds in developing countries cannot afford these t...

OBJECTIVE To analyse the mutational spectrum, the associated haplotypes and the genotype-phenotype correlation, and to design a reliable and rational approach for CYP21 mutation detection in Slovenian congenital adrenal hyperplasia (CAH) patients. DESIGN Molecular analysis of the CYP21 gene was performed in 36 CAH patients and 79 family members. METHODS Southern blotting, sequence-specific ...
