Major surface glycoprotein (Msg), the most abundant cell surface protein of Pneumocystis, plays an important role in the interaction of this opportunistic pathogen with host cells, and its potential for antigenic variation may facilitate evasion of host immune responses. In the present study, we have identified and characterized the promoter region of msg in 3 species of Pneumocystis: P. carini...
A region of the rat growth hormone gene and 5' flanking DNA has been identified which promotes accurate, thyroid hormone-regulated transcriptional initiation. GC rat pituitary tumor cells were transfected with chimaeric plasmids containing various lengths of rat growth hormone gene and 5' flanking DNA fused to the coding region of the dominant selectable marker gene neo. Thyroid hormone inducti...
Citrinin, a secondary fungal metabolite of polyketide origin, is moderately nephrotoxic to vertebrates, including humans. From the red-pigment producer Monascus purpureus, a 21-kbp region flanking pksCT, which encodes citrinin polyketide synthase, was cloned. Four open reading frames (ORFs) (orf1, orf2, orf3, and orf4) in the 5'-flanking region and one ORF (orf5) in the 3'-flanking region were ...
Bovine embryonic stem cells have potential for use in research, such as transgenic cattle generation and the study of developmental gene regulation. The Nanog may play a critical role in maintenance of the undifferentiated state of embryonic stem cells in the bovine, as in murine and human. Nevertheless, efforts to study the bovine Nanog for pluripotency-maintaining factors have been insufficie...
Although microsatellites are ubiquitous in eukaryota, the number of available markers varies strongly among taxa. This meta-analysis was conducted on 32 insect species. Sequences were obtained from two assembled whole genomes, whole genome shotgun (WGS) sequences from 10 species and screening partial genomic libraries for microsatellites from 23 species. We have demonstrated: (1) strong differe...
Examination of polymorphisms in the Plasmodium falciparum gene for falcipain 2 revealed that this gene is one of two paralogs separated by 10.8 kb in chromosome 11. We designate the annotated gene denoted chr11.gen_424 as encoding falcipain 2A and the annotated gene denoted chr11.gen_427 as encoding falcipain 2B. The paralogs are 96% identical at the nucleotide level and 93% identical at the am...
In this study, we intended to genotype 2 single nucleotide polymorphisms (SNPs) of tumor necrosis factor α-induced protein 3 (TNFAIP3) genes and explore an association of TNFAIP3 genetic polymorphism with the patients of myasthenia gravis (MG) at clinical level. In brief, 215 of adult MG patients were divided into subgroups according to their clinical features, age of onset, thymic pathology, a...
The renin-angiotensin system plays a major role in regulating blood pressure and maintaining electrolyte and volume homeostasis. Previously, the angiotensinogen gene, which encodes the key substrate for renin within this system, has been reported linked to and associated with essential hypertension in White Europeans, African-Caribbeans, and Japanese. Therefore, we investigated whether the angi...
The Sca-1 antibody recognizes antigens encoded by members of the Ly-6 multigene family. These antigens are expressed on fetal and adult hematopoietic stem cells, progenitor cells, mature activated T cells, and some nonhematopoietic cells and are most likely encoded by the Ly-6E.1 and Ly-6A.2 genes. Characterization and isolation of regulatory elements of Ly-6E.1 and A.2 genes that govern tissue...
The complete sequence of the CD72 gene from the C57L mouse, including the 5' and 3' flanking sequences, is reported. The gene spans 6830 base pairs and includes nine exons surrounding eight introns. It does not have an obvious TATAA box, so it belongs to a group of genes with TATA-less promoters that are regulated during mammalian immunodifferentiation. cDNA sequence comparisons among CD72a, CD...
