Glykosylace povrchové membrány EL-4 buněk: vliv volného nebo N-(2-hydroxypropyl)methacrylamide (HPMA) vázaného doxorubicinu
Kovář, Lubomír ; Etrych, Tomáš ; Šubr, Vladimír ; Strohalm, Jiří ; Sklenář, Jan ; Chytil, Petr ; Ulbrich, Karel ; Říhová, Blanka
In those experimenst we studied the possible impace of CD43 as highly glycosylated molecule in cells exposed to free doxorubicin (Dox) or to conjugates consisting of HPMA copolymer backbone to which the drug is conjugated via enzymatically (PK1 conjugate) or pH sensitive, hydrolytically cleavable bond (hydrazone conjugate, HYD).
Imunostimulační a imunoprotektivní vlastnosti makromolekulárních protinádorových léčiv

Polymeric conjugates of doxorubicin, non-targeted or antibody targeted cure mice from experimental EL4 T cell lymphoma and induce specific, systemic long-lasting anti/tumor resistance
Vliv N-(2-hydroxypropyl)methacrylamidového kopolymeru obsahujícího doxorubicin na mitogenem aktivované protein kinázové signalizační dráhy
Kovář, Lubomír ; Strohalm, Jiří ; Chytil, Petr ; Plocová, Daniela ; Mrkvan, Tomáš ; Ulbrich, Karel ; Říhová, Blanka
We demonstrated that the mitogen-activated protein kinases (MAPKs) play a crucial role in cancer cell death and survival, however their role seems to be indirect. We confirmed the previously published results showing that different intracellular processes are underway in cancer cells treated with Dox.HCl compared to those incubated with HPMA conjugates
Mechanismus cytotoxicity polymerních léčiv založených na HPMA je závislý na jejich intracelulárním osudu
Hovorka, Ondřej ; Strohalm, Jiří ; Etrych, Tomáš ; Ulbrich, Karel ; Říhová, Blanka
Intracellular cleavage of doxorubicin is not a necessary prerequisite for the pharmacological activity of HPMA-based conjugates. Composition of the spacer bearing drug, and the way of doxorubicin binding strongly influences intracellular distribution of polymeric drugs and in that way the mechanism of cell death
Kopolymery na bázi HPMA s pH-řízeným uvolňováním doxorubicinu v protinádorové terapii umožňují imunitnímu systému rozpoznat nádor
Mrkvan, Tomáš ; Šírová, Milada ; Etrych, Tomáš ; Chytil, Petr ; Strohalm, Jiří ; Plocová, Daniela ; Ulbrich, Karel ; Říhová, Blanka
Therapy with HPMA-based conjugates triggers effective anti-tumour immunity early during the course of the treatment. Activated immune system, in addition to direct cytotoxic effect the drug, is responsible for the eradication of established tumour
Protinádorová účinnost konjugátu na bázi N-(2-hydroxypropyl)metakrylamidu, obsahujícího doxorubicin a normální lidský imunoglobulin
Šírová, Milada ; Strohalm, Jiří ; Rossmann, Pavel ; Mrkvan, Tomáš ; Šubr, Vladimír ; Plocová, Daniela ; Ulbrich, Karel ; Říhová, Blanka
Polymeric conjugate based on HPMA containing cytotoxic drug (doxorubicin) and human “non-specific” immunoglobulin has a significant anti-tumour effect and does not impair immune functions of the host. C57BL/6 mice with EL-4 lymphoma, when completely cured with the conjugate, were protected against the same tumour due to a specific anti-tumour immune reaction
