Molecular cloning, gene organization, and expression of mouse Mpi encoding phosphomannose isomerase.
Phosphomannose isomerase (PMI) interconverts fructose-6-P (Fru-6-P) and mannose-6-P (Man-6-P), linking energy metabolism to protein glycosylation. We have cloned the mouse Mpi cDNA, analyzed its genomic organization, and studied the expression in different tissues. The Mpi gene has eight exons covering 7.2 kb. The structure and intron-exon boundaries are essentially the same as its human orthol...
Natural antisense transcripts (NATs) are important regulators of gene expression. Recently, a link between antisense transcription and the formation of endo-siRNAs has emerged. We investigated the bi-directionally transcribed Na/phosphate cotransporter gene (Slc34a1) under the aspect of endo-siRNA processing. Mouse Slc34a1 produces an antisense transcript that represents an alternative splice p...
TGF-beta superfamily members including bone morphogenetic proteins (BMPs) and their receptors (BMPR-1A, -1B and -2) have been shown to be important for reproductive function in both males and females, while information on the role of BMPs in males is limited. Functional studies on select BMPs and BMP receptors have demonstrated vital roles for these proteins in somatic and germ cell proliferati...
The bactericidal/permeability-increasing protein (BPI), stored in human neutrophil granulocytes, is cytotoxic against Gram-negative bacteria. Several genes related to BPI cluster on human chromosome 20 and on mouse chromosome 2, but expression and characterization of a BPI ortholog in the mouse have not been reported. We asked whether BPI is structurally and functionally conserved between human...
Background: Formaldehyde (FA, H2CO), a member of the aldehyde family and one of the simplest organic molecules, is a flammable, pungent, irritating and colorless gas. This study aimed to investigate the effect of formaldehyde (FA) vapor on sperm parameters and testicular tissue concern about the duration of analysis and the amount of the formaldehyde vapor concentrations. Materials and Methods:...
A determination of the absolute amounts of high-mobility-group proteins 1 and 2 (HMG1 and HMG2) in rat tissues demonstrated that amounts of HMG2 were low in non-proliferating tissues, somewhat higher in proliferating and lymphoid tissues, but were extremely elevated in the testis. This increase was due to a germ-cell-specific form of HMG2 with increased mobility relative to somatic HMG2 on acid...
