The present study was designed to investigate comparative expressions of follicle-stimulating hormone beta subunit (FSHβ) and nuclear receptor coactivator 1 (NCOA1) genes by real-time polymerase chain reaction, using polymerase chain reaction single-strand conformation polymorphism methods to investigate the effects of gene polymorphisms on reproductive traits, including total number of kits born (TNB) and number of born alive (NBA) in pink-eyed white mink. Four single-nucleotide polymorphisms were identified in the FSHβ and NCOA1 genes. The g.1228G>A polymorphism of FSHβ was associated with NBA and TNB (P < 0.01). The g.151536T>C polymorphism of NCOA1 was associated with NBA and TNB (P < 0.01). The NCOA1 mRNA levels in hypothalamus, ovary, and uterus during the first half of gestation were higher than during the middle term and last half of gestation (P < 0.01). The FSHβ mRNA levels in the hypothalamus and uterus were higher during the first half of gestation than during the middle term and last half of gestation (P < 0.05). In conclusion, the g.1866T>C polymorphism of FSHβ and the g.151536T>C polymorphism of NCOA1 could be molecular markers for reproductive traits, and expressions of FSHβ and NCOA1 might be involved in the regulation of embryo attachment mechanisms in pink-eyed white mink breeding.

Abstract We have developed a technique to diagnose the alpha- and beta- thalassemia (thal) syndromes using the polymerase chain reaction to amplify cDNA copies of circulating erythroid cell messenger RNA (mRNA) so as to quantitate the relative amounts of alpha-, beta-, and gamma- globin mRNA contained therein. Quantitation, performed by scintillation counting of 32P-dCTP incorporated into specific globin cDNA bands, showed ratios of alpha/beta-globin mRNA greater than 10-fold and greater than fivefold increased in patients with beta 0- and beta (+)- thal, respectively, as well as a relative increase in gamma-globin mRNA levels. Conversely, patients with alpha-thalassemia showed a decreased ratio of alpha/beta-globin mRNA proportional to the number of alpha- globin genes deleted. This methodology of ascertaining ratios of globin mRNA species provides a new, simplified approach toward the diagnosis of thalassemia syndromes, and may be of value in other studies of globin gene expression at the transcription level.

Abstract The regulation of erythropoietin (Epo) production was investigated by competitive polymerase chain reaction, a highly sensitive and accurate means of measuring Epo mRNA levels. Co-amplification of the test sample with added mutant Epo cDNA template corrects for variability in the efficiency of amplification. Epo mRNA levels were determined in tissues of normal rats and in animals with varying degrees of anemia. Reduction of the hematocrit level from 0.40 to 0.15–0.20 resulted in a 300-fold increase in kidney Epo mRNA, which comprised 80% of the total Epo mRNA versus 20% from the liver. In contrast, very low levels detected in lung and spleen were not significantly increased by anemia. The human hepatoma cell line, Hep3B, secretes high levels of Epo in response to hypoxia. This regulation is, to a large extent, transcriptional. When Hep3B cells were incubated in the presence of decreasing O2 tension from 160 to 7 mm Hg, there was a monotonic increase in Epo mRNA to 50 to 100 times the normoxic level. Hyperoxia did not suppress basal expression. When cells were incubated at a PO2 of 7 mm Hg, induction of Epo mRNA was first noted at 30 minutes and was maximal at 5 to 6 hours. After Epo mRNA was boosted by a 4-hour hypoxic incubation, cells were then exposed to normoxia, which shut off further transcription of the Epo gene. The decay of Epo mRNA levels closely followed first order kinetics with a half-life of 2 hours, an effective measurement of message stability.

BACKGROUND: The proinflammatory chemokine CXCL10, in addition to its chemotactic properties, is also involved in the stimulation of natural killer and T-cell migration inMycobacterium tuberculosisinfection. In this study, our experiments were designed to determine the role of interferon (IFN)-αβ in the production of CXCL10 by human monocytes infected withMycobacterium bovisbacillus Calmette-Guérin (BCG).Methods: The concentrations of CXCL10 in culture supernatants of monocytes infected withM. bovisBCG were determined by enzyme-linked immunosorbent assay. CXCL10 mRNA levels were determined by the reverse transcription-polymerase chain reaction method.Results: We have shown the induction of CXCL10 following infection withM. bovisBCG in a dose-dependent and time-dependent manner. Importantly, the secretion of CXCL10 in response toM. boviswas increased by IFN-α. These results were further confirmed by the fact that the addition of an anti-IFN-αβ neutralizing antibody completely reversed the stimulatory effect, whereas an isotype-matched control antibody had no significant effect on CXCL10 secretion. It is important to note that no significant effect of type I IFN on CXCL8 production inM. bovis-infected monocytes was observed. This was consistent with the finding by the reverse transcription-polymerase chain reaction method that treatment with anti-IFN-α/β antibodies potentially inhibited CXCL10 mRNA levels, whereas no significant effect was observed on CXCL8 mRNA. Moreover, in THP-1 monocytes and THP-1 macrophages, the addition of exogenous IFN-α stimulated CXCL10 secretion.Conclusions: Collectively, these results indicate that the type I IFN may play an important role to modulate the expression of CXCL10 inM. bovisBCG infection. Studies onM. bovis-induced chemokine secretion could provide important insight into the regulation of the immune response against tuberculosis.
