Women of reproductive ages are varies in their responses to exogenous FSH stimulations. The difference of FSHR genotype due to the polymorphisms in exon 10 is one of its significant factors. To know further whether the core promoter of FSHR is also polymorphic and to know whether those polymorphisms influence the promoter activity, we did polymorphism screening of FSHR promoter to 262 women undergoing IVF/ICSI, followed by functional study to know the impact of polymorphisms to the promoter activity. This study indicated that the core promoter of human FSHR is polymorphic. We found five SNPs at positions â29, â37, â114, â123 and â138 in addition to the variety number of adenines. Polymorphism at position â123 significantly decreased the promoter activity, in contrast, polymorphism at position â37 and â138 significantly increased the promoter activity, whereas polymorphism at position â29, â114 and short adenines stretch did not significantly influence the promoter activity. The differences of the promoter activities due to polymorphisms might change the ovarian sensitivity to FSH.

Aim This study explored the expression of HIF-1Î± in hypoxic cardiac muscle in mice, and observed the evidence of apoptosis in hypoxia induced cardiomyocyte.Methods Male Sprague-Dawley rats, were randomized into 7 groups (n = 4 per group): control normoxia group that was exposed to atmospheric oxygen and hypoxia groups that were housed in hypoxic chambers (O2 level 8%) for 1, 3, 7, 14, 21, and 28 days respectively. Animals were sacrificed, hearts were rapidly excised, total RNA was extracted with an mRNA isolation kit and the expression of HIF-1Î± mRNA was then detected by real-time RT-PCR. Apoptosis was assessed by TUNEL method.Results For rat in hypoxia group, the expression of HIF-1Î± mRNA in cardiac myocytes was clearly up-regulated compared to the control normoxia group. Further, HIF-1Î± expression level elevated gradually and reached a peak at 21 days of hypoxia. No cell labeled by the TUNEL method was detected in the control group. Compared with the control group, the apoptotic index was significantly increased in the hypoxia group (P < 0.05). There was no significant correlation between the elevation of HIF-1Î± mRNA and the elevation of apoptotic index.Conclusion Systemic chronic hypoxia caused the elevation of HIF-1Î± mRNA and apoptosis in cardiac myocytes.

The study was an experimental study with pre- and post-test design, to evaluate the effects of tomato juices (Lycopersicum esculentum Mill) consumption on plasma lycopene level. Blood sample of 27 subjects with average age of 34.70 Â± 5.74 years old, moderate education level (85.2%), experienced direct contact with working environmental pollutant (40.74%) and smoked kretek cigarettes (77.78%) were given treatment with 350 gram/day of tomato juices (Lycopersicum esculentum Mill) which had been properly prepared for 4 consecutive days. The lycopene plasma level was examined before and after treatment. The findings showed that after treatment, the lycopene plasma level significantly increased. This showed that consumption of properly prepared of tomato juices will increase the lycopene plasma level. (Med J Indones 2004; 13: 146-50) Keywords: light smoker, tomato juices, lycopene plasma

Aldehyde dehydrogenase (ALDH) plays a pivotal role in the alcohol metabolism. Decreased activity of ALDH enzyme has more influence on the hypersensitivity to alcohol than of alcohol dehydrogenase. ALDH enzyme exists in several isozymes. Among these isozymes, ALDH2 is a major isozyme that has a very high affinity for acetaldehyde. Recent studies suggested that the deficiency of ALDH2 may be inherited. Functional polymorphism of ALDH2 gene has been observed in a nucleotide of the 487th codon. In the atypical gene, this codon consists of AAA nucleotides for lysine, instead of GAA for glutamic acid in the wild type gene. In this study, we have analyzed the genetic polymorphism of ALDH2 gene among 100 Indonesian students using genomic DNA extracted from hair roots. Polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) methods were performed for this purpose. Three oligonucleotide primers were designed for two steps PCR. The reverse primer R was intentionally constructed not to be 100% complementary to the template strand, to generate a restriction site for Eco RI within the variable nucleotide in the PCR product of ALDH2 gene. This study indicates that 70 subjects (70%) have wild type, 29 (29%) atypical heterozygote and only 1 (1%) atypical homozygote ALDH2 alleles. Conclusively, the atypical ALDH2 allele frequency in Indonesians (31/200) is higher than in Caucasoids (only about 5-10%), but less than in Mongoloids (40-50%). This may be due to the diverse ethnics of Indonesian population. (Med J Indones 2002; 11: 135-42) Keywords: alcohol hypersensitivity, genetic polymorphism, aldehyde dehydrogenase-2 (ALDH2) gene

Malaria poses a major public health problem in Papua. The rapid spread of drug-resistant parasites and deterioration of the malaria control program following the monetary crisis and civil strife in the late 90âes have worsened the malaria situation in many areas of Papua. To re-assess the current magnitude of malaria problem, a malariometric survey was conducted in three sub-districts of Jayapura District, as well as antimalarial drug sensitivity test using sulfadoxine-pyrimethamine (SP) at the outpatient clinics of Abepura General Hospital (RSU), Hamadi Primary Health Center and Panti Asuhan Katolik Clinics, Sentani, Jayapura District, Papua Province. Screening of 543 subjects in three sub-districts revealed 185 malaria positive subjects, either with P. falciparum, P. vivax or mixed of the two species. All of the malaria cases were asymptomatic. In the SP drug sensitivity test, of the 56 subjects involved, 32 were classified as early treatment failure and two subjects were classified as late treatment failure. The remaining 22 subjects were classified as adequate clinical and parasitological response (ACPR). These results indicated that the surveyed area has a high malaria prevalence and treatment failure to SP and therefore alert to the need of deploying new antimalarial regiment that suit the remote setting.

Background: Liver is sensitive against hypoxia and hypoxia will stabilize HIF-1Î±. At the same time, hypoxia will produce reactive oxygen species (ROS) which can be scavenged by Cygb. The purpose of our study is to know, if normobaric hypoxia can induce Cygb expression and its association with HIF-1Î± stabilization.Methods: This is an experimental study using 28 male Sprague-Dawley rats, 150-200 g weight. Rats are divided into 7 groups: control group and treatment groups that are kept in hypoxic chamber (10% O2: 90% N2) for 6 hours, 1, 2, 3, 7 and 14 days. All rats are euthanized after treatment and liver tissue are isolated, homogenized and analyzed for oxidative stress parameter, expression of Cygb and HIF-1Î±.Results: Expression of Cygb mRNA and protein was increased on the day-1 after treatment and reach the maximum expression on the day-2 of hypoxia treatment. But, the expression was decreased after the day-3 and slightly increased at the day-14 of hypoxia. The correlation between expression of Cygb and oxidative stress parameter was strongly correlated. Cygb mRNA, as well as protein, showed the same kinetic as the HIF-1, all increased about day-1 and day-2.Conclusion: Systemic chronic hypoxia and/or oxidative stress up-regulated HIF-1Î± mRNA which is correlated with the Cygb mRNA and protein expression. Cygb mRNA as well as Cygb protein showed the same kinetic as the HIF-1, all increased about day-1 and day-2 suggesting that Cygb could be under the regulation of HIF-1, but could be controlled also by other factor than HIF-1.

Background: Hypoxia results in an increased generation of ROS. Until now, little is known about the role of MnSOD - a major endogenous antioxidant enzyme - on the cell adaptation response against hypoxia. The aim of this study was toÂ determine the MnSOD mRNA expression and levels of specific activity in blood, heart and brain of rats during induced systemic hypoxia.Methods: Twenty-five male Sprague Dawley rats were subjected to systemic hypoxia in an hypoxic chamber (at 8-10% O2) for 0, 1, 7, 14 and 21 days, respectively. The mRNA relative expression of MnSOD was analyzed using Real Time RT-PCR. MnSOD specific activity was determined using xanthine oxidase inhibition assay.Results: The MnSOD mRNA relative expression in rat blood and heart was decreased during early induced systemic hypoxia (day 1) and increased as hypoxia continued, whereas the mRNA expression in brain was increased since day 1 and reached its maximum level at day 7. The result of MnSOD specific activity during early systemic hypoxia was similar to the mRNA expression. Under very late hypoxic condition (day 21), MnSOD specific activity in blood, heart and brain was significantly decreased. We demonstrate a positive correlation between MnSOD mRNA expression and specific activity in these 3 tissues during day 0-14 of induced systemic hypoxia. Furthermore, mRNA expression and specific activity levels in heart strongly correlate with those in blood.Conclusion: The MnSOD expression at early and late phases of induced systemic hypoxia is distinctly regulated. The MnSOD expression in brain differs from that in blood and heart revealing that brain tissue canÂ possibly survive better from induced systemic hypoxia than heart and blood. The determination of MnSOD expression in blood can be used to describe its expression in heart under systemic hypoxic condition.

Background: Cobalt chloride can be used as an agent to stabilize hypoxia inducible factor-1Î± (HIF-1Î±) and to imitate hypoxia without low levels of oxygen inside the body. We intended to investigate if there was any regulation of renin expression by HIF-1Î±. Therefore, we conducted several studies to clarify this possibility starting with the induction of hypoxic mimicry in rats by intra-peritoneal (IP) injection of cobalt chloride (CoCl2) to obtain the levels and pattern of HIF-1Î± and renin mRNA and protein expression.Methods: Twenty-four rats were randomly divided into four groups, control group and incubation groups 2, 8, and 24 hours after intra-peritoneal injection of 30 mg CoCl2 per kg BW. After the rats were sacrificed, kidneys were excised, weighed and kidney weight compared to BW. Tissue parameters were measured such as RNA concentration, HIF-1Î± protein by ELISA, and renin mRNA by RT-PCR.Results: Differences between the groups in the ratios of kidney weight to BW and in the concentrations of HIF-1Î± protein were statistically not significant (p > 0.05). Relative expression of renin mRNA increased markedly starting 8 hours after CoCl2 IP injection (30 times over controls) and further rising until 24 hours (2465 times over controls). Correlation between HIF-1Î± and renin mRNA by Pearson analysis was strongly positive, but not significant (R = 0.91; p = 0.09).Conclusion: Renin gene regulation in renal hypoxic mimicry strongly correlates with HIF-1Î±.

Background: Tumor tissue usually became hypoxic due to disruption of oxygen supply. Adaptation response to hypoxia is mediated by transcription factor, hypoxia- inducible factor-1Î± (HIF-1Î±). HIF-1Î± signaling is known to increase the expression of pro-apoptotic protein cytochrome-c, and anti- apoptotic survivin. In this study we wanted to analyze the role of HIF-1Î± on breast cancer cells survival through pro-apoptosis cytohrome-c and anti-apoptosis survivin regulation.Methods: Breast cancer cell lines T47D were induced by CoCl2 then harvested to analyze the expression of HIF-1Î±, protein cytochrome-c, mRNA survivin and cell viabilities.Results: HIF-1Î± induction by CoCl2 causes the increase of Â protein and mRNA of HIF-1Î±, cytochrome-c protein, and survivin mRNA, but does not cause the changes in cell viability.Conclusion: HIF-1Î± induction have no effects on breast cancer cell line T47D viabilities due to the balance regulation between pro-apoptosis expression cytochrome-c and anti-apoptosis survivin.
