Antitumor triazoloacridinone C-1305 as a potent FLT3 tyrosine kinase inhibitor in human acute myeloid leukemia (AML) cells.
PublicationJednym z defektów molekularnych u pacjentów z ostrą białaczką szpikową (AML) jest konstytutywna aktywacja receptoroweej kinazy tyrozynowj FLT3.Najczęstszą mutacją genu kodującego FLT3 jest wewnętrzna tandemowa duplikacja ITD we fragmencie okołobłonowym receptora. W pracy zbadano, czy przeciwnowotworowy triazoloakrydon C-1305 może być inhibitorem kinazy tyrozynowej FLT3. Badania przeprowadzono na dwóch liniach komórkowych białaczek...

The effect of cabbage juice and it's active components on the protein level and expression of CYP19 in MCF-7 breast cancer cells
PublicationWiadomo, że bioaktywne skladniki kapusty mają chemoprewencyjne działanie w przypadku nowotworów piersi, między innymi ze względu na hamowanie aktywności enzymu aromatazy uczestniczącego w biosyntezie estrogenów. Badania prowadzono przy użyciu komórek raka piersi i stwierdzono, że soki z kapusty, zarówno pochodzącej z uprawy ekologicznej jak i przemysłowej, znacząco hamowały ekspresję genu CYP19 kodującego wspomniany enzym. Sugeruje...

Structure modification of acridine antitumor agents results in changes of enzymatic activity and gene expression of CYP3A4 isoenzyme in HepG2 cells.
PublicationEkspresja izoenzymu CYP3A4, który zaangażowany jest w metabolizm ok. 60% leków stosowanych klinicznie, może być modulowana przez takie czynniki jak: polimorfizm, czynniki transkrypcyjne oraz obecność ksenobiotyków. Przykładem induktorów genów kodujących izoenzym CYP3A4 jest fenobarbital i rifampicyna, których obecność w organizmie przyspiesza metabolizm innych leków stosowanych jednocześnie, które są substratami dla CYP3A4. Dlatego...

Low temperature deposition of dense MnCo 2 O 4 protective coatings for steel interconnects of solid oxide cells
PublicationIn this work manganese cobalt spinel (MnCo2O4) coatings were deposited on steel substrates by spray pyrolysis at 390 °C. This is at much lower temperatures than previously reported (typically in excess of 900 °C). It was possible to produce coatings with well controlled thickness (2-5-10 μm). The as-deposited coatings were evaluated for their microstructural changes and electrical conductivity up to 800 °C. Results confirm the...

Influence of titanium layer on counter electrode on electrical parameters of DSSC
PublicationIn this paper the influence of the Ti layer thickness at counter-electrode on electrical parameters of DSSCs was examined. The transparent conductive oxide – less (TCO-less) counter electrodes (CE) with titanium layers and platinum as catalyst on Bk7 glass were prepared. Thin metallic films were deposited by means of magnetron sputtering (titanium) and Pulsed Laser Deposition (platinum). The counter electrode with Pt layer on Fluorine...

The influence of the thickness, recombination and space charge on the loss of photocurrent in organic semiconductors: an analytical model
PublicationWe propose an analytical model of the photocurrent efficiency dependence on the light intensity in organic semiconductors. The influence of the thickness of sample, space charge effects and recombination of charge on the loss of photocurrent has been considered. We demonstrate that the presented model is the enhancement of an analytical model reported recently by Rappaport et al (2005 J. Appl. Phys. 98 033714). The method to identify...

Antitumor 1-nitroacridine derivative C-1748, induces apoptosis, necrosis or senescence in human colon carcinoma HCT8 and HT29 cells.
PublicationC-1748 jest związkiem oddziaływującym z DNA i potencjalnym związkiem przeciwnowotworowym szczególnie wobec nowotworów prostaty i jelita grubego przeszczepialnych na myszach.W pracy badano odpowiedź komórek nowotworowych HCT8 i HT29 na działanie pochodnej C-1748, w stężeniach biologicznie istotnych (EC90). Analiza cyklu komórkowego linii HCT8 pokazała, że związek powoduje wzrost frakcji sub-G1, świadczący o apoptozie tych komórek...

C421 allele-specific ABCG2 gene amplification confers resistance to the antitumor triazoloacridone C-1305 in human lung cancer cells
PublicationGen ABCG2 charakteryzuje polimorficzność pozycji C341, która jest związana ze znacznym obniżeniem ekspresji tego genu i zdolności do transportu przez błonę komórkową. W pracy wykazaliśmy, że komórki raka płuc, które nabyły oporności na związek C-1305, zmieniły fenotyp z heterozygotycznego w odniesieniu do genu ABCG2 i wykazują amplifikację jedynie allelu C341 genu oraz zwiększoną zawartość mRNA i zmutowanego białka pompy ABCG2...

Oxidative stress induced by 4-methyl-1-nitroacridine derivative C-1748 (Capridine B) in human colon cancer cells
PublicationZbadano wpływ pochodnej C-1748 (Capridine B) na indukcję stresu oksydacyjnego w komórkach ludzkich raków jelita grubego HCT-8 i HT29. W tym celu wykorzystano technikę cytometrii przepływowej z zastosowaniem barwników fluorescencyjnych H2DCFDA i DHR 123. W komórkach traktowanych pochodną C-1748 dochodziło do generowania reaktywnych form tlenu. Ponadto, pochodna C-1748 nie indukowała znaczącego spadku zawartości zredukowanej formy...
