Lege Artis Medicinae - 2004;14(03)

[In this review we summarise the current results of the genomic investigation of allergic diseases. From the genetic point of view allergy is multifactorial, which means that the susceptibility to the disease is determined by the effect of one or more genes or the interactions between multiple genes and involves important nongenetic factors such as the environment for their expression. Among allergic diseases the genomic background of asthma was studied most thoroughly. Until now, using hundreds of DNA markers, located across all of the human chromosomes, 16 genome-wide screens for susceptibility genes for asthma or asthma related intermediate phenotypes in 12 different populations have been published and 20 chromosomal regions have been highlighted for further analysis. In genetic association studies more than 500 genes were identified as candidate genes for asthma. In this review, we selected those results which were consistently reported by several independent studies or appeared particularly important or interesting. According to the results of the human genome programs and association studies we discuss the possible roles of candidate genes found in these loci in the pathomechanism of allergy and atopy.]

[THE PROBLEM OF SMOKING]

RODÉ Magdolna

[Smoking causes a health catastrophy all over the world. Its importance is increasing in the less developed countries. More and more young people (especially women) have started smoking recently. Its devastating effect on women carries on to the next generations. Prevention should already begin in childhood. In Hungary, there is a wide network to assist for those who want to give up smoking - especially in the national network of lung health care clinics. Peer supporters have a prominent role in helping these patients. The market-strategy and publicity campaign of major tobacco producers also deserves intensive attention.]

[Risk to the fetus in the light of new data]

BODA Domokos

[Extensive research efforts based on principles of evidence-based medicine have helped lately to accumulate large amount of information on the risks to the fetus during pregnancy. As a result, the standpoints concerning risks to the fetus have become more precise in many respects. A number of earlier assumptions have been proven to be exaggerated or unfounded and the range of cases at risk has been narrowed down. This paper presents the most important data on potential risks to the fetus originating from hereditary factors, infections, maternal diseases, drugs, irradiation and special gestational anomalies. The data presented highlight the necessity of identifying the fetal damage during the pregnancy unequivocally, based exclusively on evidence of probative force and with realistic appraisal of the danger of any existent fetal damage.]

[Molecular biology of 70 kD heat shock protein and its role in certain immunological processes]

KOCSIS Judit, FÜST György, PROHÁSZKA Zoltán

[Heat-shock proteins, or stress proteins play important role in cellular survival owning to their protective function. Their highly conserved structure renders them ideal messengers of cellular stress response. One of the best known representative of these proteins is the 70 kDa heat-shock protein (Hsp70), there is increasing amount of data about the intraand extracellular functions of this stress protein. In the present review the regulation of hsp70 gene expression, and hsp70 polimorfisms, the possible impact of polymorphisms to certain diseases, and the multilevel relationship between Hsp70 and the immun response are discussed. The authors review the role of Hsp70 in anti-tumor immunity, and the presence of anti-Hsp70 antibodies and their possible association with certain diseases. Here they present some of their recent observations: they detected the presence of anti-Hsp70 antibodies in all adult sera and found no correlation between these antibody levels and the presence of severe coronary heart disease. Recently we also showed, that human Hsp70 can activate the classical pathway of complement system in vitro, by direct binding of the first complement C1q.]

[Human genome project]

SASVÁRI-SZÉKELY Mária

[The main goal of the Human Genom Project is to reveal the complete structure of the human DNA, involving the sequence determination of the three billion basepairs. The program was launched in 1990, executed in laboratories of the public sector in several countries. Results of this project are made public on the Internet. In 1998 a private sector company, Celera, was founded with the same goal. In 2001 both projects announced the accomplishment of the first draft of the Human Genome. A whole issue of Nature and Science magazine was devoted to present the first results of their findings. According to the results less than one percent of the genetic information is transcribed to proteins. The estimated number of genes was also lower than expected (30-40 thousand, which number recently increased to 40-60 thousand). Based on these findings, human complexity should be ascribed to the variability of the information units (domains) rather than to the number of genes. Once the complete sequence of the humane genome is accomplished, the ’pre-genomic era’ will be over and the ’post-genomic era’ will begin, dealing with understanding the genetic information, annotating the genes and mapping the genetic variability of people.]

FALUS ANDRÁS, BERKE Tamás, ORTUTAY Csaba Péter, SUHAI György

[Bioinformatics is one of the most important element of genomic research revolutionising biomedical science. This review describes the phenomena of genomic variance and comparative genomics. Briefly, the review summarises the identification procedure of new genes and gene expression patterns highly important in diagnostics. Bioinformatic procedures make possible the rapid detection of pathogens and have principal role in molecular drug design technologies.]

[Association between the genetic polymorphism of heat-shock protein 72 and pediatric kidney diseases]

[Recurring urinary tract infections (UTI) in childhood may result in chronic- and end-stage-renal-disease (ESRD), which leads to the initiation of dialysis and renal transplantation (NTx). Heat shock protein (HSP) 72 protects the kidney, whereas it refolds destroyed proteins and cells, and helps regenerating the renal tissue. The HSPA1B (1267)G allele is associated with lower HSP72 expression. This study assesses the role of HSPA1B A(1267)G polymorphism using PCR-RFLP in 103 children treated because of recurrent UTI, 26 children after NTx and 235 healthy controls. Clinical data were also evaluated. HSPA1B (1267)GG genotype and HSPA1B (1267)G allele occurred more frequently in the UTI (p=0.0001; CI: 1.378-2.68) and in the NTx (p=0.014; CI: 2.29-187.7) patient group than in the controls group, and were associated with a higher risk for scarring (p=0.012; CI: 0.33-1.00) and renal malformation (p=0.0072; CI: 1.623- 140.6). Our data indicate a relationship between the carrier status of HSPA1B (1267)G allele and the development of recurrent UTI and ESRD, raising further questions about the clinical and therapeutic relevance of these polymorphism.]
