Two small RNAs conserved in Enterobacteriaceae provide intrinsic resistance to antibiotics targeting the cell wall biosynthesis enzyme glucosamine-6-phosphate synthase
PublikacjaFormation of glucosamine-6-phosphate GlcN6P) by enzyme GlcN6P synthase (GlmS) represents the first step in bacterial cell envelope synthesis. In Escherichia coli, expression of glmS is controlled by small RNAs (sRNAs) GlmY and GlmZ. GlmZ activates the glmS mRNA by base-pairing. When not required, GlmZ is bound by adapter protein RapZ and recruited to cleavage by RNase E inactivating the sRNA. The homologous sRNA GlmY activates...

Novel anticancer strategy aimed at targeting shelterin complexes by the induction of structural changes in telomeric DNA: hitting two birds with one stone.
PublikacjaThe ends of chromosomes in mammals are composed of telomeric DNA containing TTAGGG repeats, which bind specific proteins called shelterins. This telomeric DNA together with shelterins form a cap that protects the ends of chromosomes from being recognized as sites of DNA damage and from chromosomal fusions. Many very successful antitumor drugs used in the treatment of cancer patients bind to DNA, some of them with a prominent sequence...

The influence of microstructure on the corrosion resistance for some titanium-based alloys
Dane BadawczeThis dataset contains scanning electron microscopy (SEM) micrographs revealing the microstructure of some Ti-based alloys, namely: Ti-6Al-4V (file name: TiV), Ti-6Al-7Nb (file name: TiNb) and TC21 (file name: TiAlSnZrMoCrNbSi) alloys and their localized corrosion as a result of passive layer breakdown in a corrosive environment, ie. 0.9% NaCl solution...

How do sterols determine the antufungal activitiy of amphotericin B? Free energy of binding between the drug and its membrane targets.
PublikacjaAmphotericin B (AmB) is a well-known polyene antibiotic used to treat systemic fungal infections. It is commonly accepted that the presence of sterols in the membrane is essential for the AmB biological activity, that is, for the formation of transmembrane ion channels. The selective toxicity of AmB for fungal cells is attributed to the fact that it is more potent against fungal cell membranes containing ergosterol than against...

Non-Gaussian Resistance Fluctuations in Gold-Nanoparticle-Based Gas Sensors: An Appraisal of Different Evaluation Techniques
PublikacjaVolatile organic compounds, such as formaldehyde, can be used as biomarkers in human exhaled breath in order to non-invasively detect various diseases, and the same compounds are of much interest also in the context of environmental monitoring and protection. Here, we report on a recently-developed gas sensor, based on surface-functionalized gold nanoparticles, which is able to generate voltage noise with a distinctly non-Gaussian...

The ability to overcome multidrug resistance of tumor cell lines by novel acridine cytostatics with condensed heterocyclic rings
PublikacjaZbadano aktywność cytotoksyczną, in vitzo dwóch nowych grup cytostatyków akrydynowych zawierających skondensowane pierścienie heterocykliczne w stosunku do komórek nowotworowych linii wrażliwych i opornych. Otrzymane wyniki potwierdziły naszą wcześniejszą hipotezę o istotnej roli pierścieni hetero-cyklicznych w pokonywaniu krzyżowej oporności wielolekowej.

Contribution of UDP-glucuronosyltransferases (UGTs) in metabolism of acridinone antitumor agents, C-1311, C-1305, and their less active structural analogues, C-1330 and C-1299
PublikacjaCelem prowadzonych badań było określenie roli UDP-glukuronylotransferaz, uważanych za najważniejsze enzymy detoksykujące, w metabolizmie pochodnych imidazo- i triazoloakrydonu. Wykazano, że najbardziej aktywne przeciwnowotworowo związki z obu grup, tj. C-1311 i C-1305 są transformowane do O-glukuronidów, w przeciwieństwie do ich metoksylowych analogów, odpowiednio związku C-1330 i C-1299. Analiza składu mieszanin reakcyjnych zawierających...
