871. Imunohistokemična analiza izražanja glukokortikoidnih receptorjev pri zgodnjem raku dojk in njihov vpliv na odgovor na zdravljenje z neoadjuvantno sistemsko terapijoMarjetka Sraka, Barbara Gazić, Primož Drev, Cvetka Grašič-Kuhar, 2024, original scientific article Abstract: Glukokortikoidni receptor (GR) je različno izražen na tumorskih in imunskih celicah raka dojk, njegova izraženost pa je morda odvisna od molekularnega podtipa raka dojk, prav tako njegova izraženost morda vpliva na odgovor na neoad-juvantno sistemsko terapijo. Naš namen je vpeljati zanesljivo imunohistokemično barvanje s protitelesi proti GR, drugi namen pa je oceniti izraženost GR na vzorcih raka dojk in preučiti, ali se ta izraža različno pri različnih podtipih in ali njegova izraženost vpliva na odgovor na neoadjuvantno sistemsko terapijo.

878. Citiranje strokovne literature v medicini : vancouvrski način citiranjaDavid Ožura, 2024, professional article Abstract: Strokovno besedilo, ki temelji na znanstvenoraziskovalnem delu, se od drugih besedil loči z doslednim sklicevanjem na ustrezne vire. V pričujočem prispevku si bomo podrobneje ogledali vancouvrski način citiranja, saj se ta slog sklicevanja najpogo-steje uporablja v medicini in zdravstvenih vedah. Predstavljeni so najpogostejši primeri navajanja osnovnih bibliografskih podatkov prispevkov v strokovnih revijah, posamičnih pri-spevkov v zbornikih, navajanja monografij ter informacijskih virov na internetu. Podani so osnovni napotki za označevanje, reproduciranje in citiranje tabel in slik s primeri. Na kratko so predstavljena tudi sodobna orodja za urejanje referenc in citiranja z njihovimi funkcionalnostmi.
Keywords: citiranje literature, znanstvene revije, medicina, vancouvrski način citiranja, orodja za organizacijo referenc in citranja, navajanje in označevanje tabel in slik, onkologija

880. Addition of 2-(ethylamino)acetonitrile group to nitroxoline results in significantly improved anti-tumor activity in vitro and in vivoAna Mitrović, Izidor Sosič, Špela Kos, Urša Lampreht Tratar, Barbara Breznik, Simona Kranjc Brezar, Bojana Mirković, Stanislav Gobec, Tamara Lah Turnšek, Maja Čemažar, Gregor Serša, Janko Kos, 2017, original scientific article Abstract: Lysosomal cysteine peptidase cathepsin B, involved in multiple processes associated with tumor progression, is validated as a target for anti-cancer therapy. Nitroxoline, a known antimicrobial agent, is a potent and selective inhibitor of cathepsin B, hence reducing tumor progression in vitro and in vivo. In order to further improve its anti-cancer properties we developed a number of derivatives using structure-based chemical synthesis. Of these, the 7-aminomethylated derivative (compound 17) exhibited significantly improved kinetic properties over nitroxoline, inhibiting cathepsin B endopeptidase activity selectively. In the present study, we have evaluated its anti-cancer properties. It was more effective than nitroxoline in reducing tumor cell invasion and migration, as determined in vitro on two-dimensional cell models and tumor spheroids, under either endpoint or real time conditions. Moreover, it exhibited improved action over nitroxoline in impairing tumor growth in vivo in LPB mouse fibrosarcoma tumors in C57Bl/6 mice. Taken together, the addition of a 2-(ethylamino)acetonitrile group to nitroxoline at position 7 significantly improves its pharmacological characteristics and its potential for use as an anti-cancer drug.
Keywords: nitroxoline derivative, cathepsin B, inhibition, tumor invasion, cell migration
