Changes in gene methylation patterns in neonatal murine hearts: Implications for the regenerative potential
PublikacjaBackground The neonatal murine heart is able to regenerate after severe injury; this capacity however, quickly diminishes and it is lost within the first week of life. DNA methylation is an epigenetic mechanism which plays a crucial role in development and gene expression regulation. Under investigation here are the changes in DNA methylation and gene expression patterns which accompany the loss of regenerative potential. Results The...

Homocitrate synthase gene as a new molecular target in diagnostics of Candida spp. infections
PublikacjaNew potential molecular target which will be investigated during this research (homocitrate synthase gen) is the innovative target other than ribosomal DNA. This gene encodes enzyme present only in fungi and some Archaea what significantly increases specificity. It also reduces risk of contamination or influence of other factors (reaction with other DNA present in sample derived from bacteria or host cells) what excludes false...

Justification of quasi-stationary approximation in models of gene expression of a self-regulating protein
PublikacjaWe analyse a model of Hes1 gene transcription and protein synthesis with a negative feedback loop. The effect of multiple binding sites in the Hes1 promoter as well as the dimer formation process are taken into account. We consider three, possibly different, time scales connected with: (i) the process of binding to/dissolving from a binding site, (ii) formation and dissociation of dimers, (iii) production and degradation of Hes1...

Cloning of the thermostable alpha-amylase gene from Pyrococcus woesei in Escherichia coli.
PublikacjaGen kodujący alfa-amylazę z Pyrococcus woesei klonowano do plazmidów pET21d(+)lub pYTB2, którymi transformowano komórki Escherichia coli. Otrzymana rekombinantowa alfa amylaza wykazuje maksymalną aktywność przy pH 5.6 w temperaturze 95 stC i przejawia około 24 % początkowej aktywności nawet po 2 godz. inkubacji w 120 stC. Duża termostabilność otrzymanego preparatu świadczy o jego przydatności do enzymatycznego upłynniania skrobi.

Wykorzystanie komórek Escherichia coli transformowanych genem termostabilnej beta-galaktozydazy z Pyrococcus woesei do wytwarzania galaktozylofruktozy
PublikacjaKomórki rekombinantowej Escherichia coli transformowane genem beta-galaktozydazy z Pyrococcus woesei wykorzystano jako biokatalizator syntezy galaktozylofruktozy. Największą aktywność syntezy wymienionego prebiotyku (7,6 g/L x godz)uzyskano w 80C przy pH 5,4, stosując jako substrat roztwór zawierający 10% laktozy i 20% fruktozy. Aktywność transgalaktozylacji nie ulegała istotnym zmianom podczas sześciu kolejnych szarż produkcyjnych.

Expression of Deinococcus geothermalis Trehalose Synthase Gene in Escherichia coli and Its Enzymatic Properties
PublikacjaA novel trehalose synthase gene from Deinococcus geothermalis (DSMZ 11300) containing 1,692 bp reading-frame encoding 564 amino acids was amplified using PCR. The gene was ligated into pET30Ek/LIC vector and expressed after isopropyl alfa-D-thiogalactopyranoside induction in Escherichia coli BL21(DE3)pLysS. The recombinant trehalose synthase (DgeoTreS) containing a His6 tag at the C-terminus was purified by metal affinity chromatography...

New, fast and cheap prediction tests for BRCA1 gene mutations identification in clinical samples.
PublikacjaDespite significant progress in cancer therapy, cancer is still the second cause of mortality in the world. The necessity to make quick therapeutic decisions forces the development of procedures allowing to obtain a reliable result in a quick and unambiguous manner. Currently, detecting predictive mutations, including BRCA1, is the basis for effectively treating advanced breast cancer. Here, we present new insight on gene mutation...

A novel method of Mycobacterium tuberculosis complex strain differentiation using polymorphic GC-rich gene sequences.
PublikacjaTuberculosis is one of the leading infectious diseases. In this work, a new genotyping method of Mycobacterium tuberculosis (Mtb) complex strain is presented. 27 Mtb genomes were analyzed for the presence of length polymorphism within polymorphic GC-rich gene sequences. Four genes, Rv3345c, Rv3507, Rv0747 and Rv3511, showing variation in length depending on the Mtb strain were selected for designing primer sequences flanking variable...

DDLMS PCR double digestion Ligation Mediated Suppression PCR - a new technique for bacterial specific differentiation
PublikacjaA new diagnostic kit for K. oxytoca specific differentiation based on ddLMS PCR (ang. double digest ligation Mediated PCR) technique is shown. As a species-specific DNA fragment pehX gene, encoding the enzyme polygalactouronase, was chosen. The genome sequence of K. oxytoca is digested with two endonucleases: AclI and BclI which cut DNA before and after pehX gene. The polymorphic DNA fragments are ligated with AclI-end-specific...

Virulence gene profiles in Staphylococcus aureus isolated from cows with subclinical mastitis in eastern Poland
PublikacjaStaphylococcus aureus is arguably the most important pathogen involved in bovine mastitis. The aim of this study was to determine the virulence gene profiles of 124 Staph. aureus isolates from subclinical mastitis in cows in eastern Poland. The presence of 30 virulence genes encoding adhesins, proteases and superantigenic toxins was investigated by PCR. The 17 different combinations of adhesin genes were identified. Occurrence...

The Relationship between Gene Activity and Nitrous Oxide Production during Nitrification in Activated Sludge Systems
PublikacjaNitrite is an important factor which inhibits the first stage of the nitrification, the effect is stronger with the decrease of the DO concentrations. NO2- presence at concentration above 15 mg N – NO2 in the aeration tanks stimulates N2O production regardless of the DO concentration. The significant nirS gene induction, observed especially during the experiments with the nitrite addition indicates that N2O production is basically...

NADPH Oxidase Gene Polymorphism is Associated with Mortality and Cardiovascular Events in 7-Year Follow-Up
PublikacjaThe CYBA gene encodes the regulatory subunit of NADPH oxidase, which maintains the redox state within cells and in the blood vessels. That led us to investigate the course of coronary artery disease (CAD) with regards to CYBA polymorphisms. Thus, we recruited 1197 subjects with coronary atherosclerosis and observed them during 7-year follow-up. Three CYBA polymorphisms: c.214C>T (rs4673), c.-932G>A (rs9932581), and c.*24G>A (1049255)...

Molecular Strategy for Survival at a Critical High Temperature in Eschierichia coli
PublikacjaThe molecular mechanism supporting survival at a critical high temperature (CHT) in Escherichia coli was investigated. Genome-wide screening with a single-gene knockout library provided a list of genes indispensable for growth at 47°C, called thermotolerant genes. Genes for which expression was affected by exposure to CHT were identified by DNA chip analysis. Unexpectedly, the former contents did not overlap with the latter except...

CHANGES TAKING PLACE IN THE KINETIC ARCHITECTURE OVER THE 20TH AND 21ST CENTURIES
PublikacjaKinematics has accompanied architecture from its beginning and is strongly associated with its evolution. Over the centuries, it has changed form and function. However, its rank grew at the beginning of the 20th century. Along with the widespread change of the design method in the early 90s of the twentieth century, its forms have become more complex. The study showed that with the development of design techniques, this time should be...
