Heme oxygenase-1 (HO-1) transgenic mice (Tg) were created using a rat HO-1 genomic transgene. Transgene expression was detected by RT-PCR and Western blots in the left ventricle (LV), right ventricle (RV) and septum (S) in mouse hearts, and its function was demonstrated by the elevated HO enzyme activity. Tg and non-transgenic (NTg) mouse hearts were isolated and subjected to ischemia/reperfusi...

The ultimate product of yeast mating-type interconversion is a stable a/alpha diploid cell. A haploid cell carrying the HO gene gives rise to a diploid cell in a two-step process: first, the cell switches mating type as a result of genetic rearrangement (cassette substitution) catalyzed by HO; then, cells of opposite type mate to form a/alpha diploids. Mating-type interconversion does not occur...

PURPOSE To understand how adults living in a low-income, public housing community characterize meaningful activity (activity that gives life purpose) and if through short-term intervention, could overcome identified individual and environmental barriers to activity engagement. METHODS We used a mixed methods design where Phase 1 (qualitative) informed the development of Phase 2 (quantitative)...

Dividend relevance has been a subject of significant recent interest for academicians and researchers in the area of hospitality finance. The subject has attracted noticeable controversy, given the stringent or no-dividend payout policies observed in many hospitality firms. This study builds on existent dividend literature in hospitality finance by examining the relevance of cash dividends for ...

The communication which I venture to bring before you this evening has three objectives in view. First, to examine the statement frequently made and supported by statistics, that puerperal mortality is as high to-day as it was seventy years ago; second, to question the opinion, also widely held, that the bulk of this mortality is the result of instrumental and other interference with the course...

Heme is an essential requirement for cell survival. Heme oxygenase (HO) is the rate-limiting enzyme in heme catabolism and consists of two isozymes, HO-1 and HO-2. To identify the protein that regulates the expression or function of HO-1 or HO-2, we searched for proteins that interact with both isozymes, using protein microarrays. We thus identified 6-phosphofructo-2-kinase/fructose-2,6-bisp...

Heme oxygenase (HO), by catabolizing heme to bile pigments, down-regulates cellular hemoprotein, hemoglobin, and heme; the latter generates pro-oxidant products, including free radicals. Two HO isozymes, the products of distinct genes, have been described; HO-1 is the inducible isoform, whereas HO-2 is suggested to be constitutively expressed. We studied the inducing effect of several metal com...

Heme oxygenase (HO) catalyzes the first and rate-controlling step of heme catabolism into biliverdin, iron and carbon monoxide. Three isoforms of HO have been identified so far: the inducible HO-1 and the constitutive HO-2 and HO-3. Both HO-1 and HO-2 were expressed in zona fasciculata (ZF) adrenal cells and in a mouse adrenocortical cell line (Y1). HO-1 but not HO-2 expression was upregulated ...
