    The research aim was to study the dynamics of biogenic amines in the brain, tumor and intact skin of urokinase (uPA) gene knockout mice on day 21 of the B16/F10 melanoma growth.Material and methods. The study included male and female uPA gene knockout (-uPA, n = 38) and wild type mice (+uPA, n = 61). Melanoma was transplanted subcutaneously. Levels of biogenic amines were studied by ELISA in tissues obtained on day 21 of carcinogenesis.Results and discussion. Intact (-uPA) mice showed an increased total content of biogenic amines: in the skin - due to noradrenaline increase by 4.8 times in males and by 4.9 times in females, histamine - by 3.6 times in males and by 1.6 times (p < 0.05) in females, serotonin - by 3.4 times in males and by 8.3 times in females; in the brain - due to noradrenaline increase by 3.5 times in males and by 3.2 times in females, dopamine by 2.1 times in males and by 2.9 times in females, while histamine content decreased. Melanoma development in (-uPA) mice was characterized by: lower levels of adrenaline with high NA concentrations and an increase in the serotonin metabolism in the brain; higher histamine concentrations in the tumor and higher serotonin levels in the skin; similar to (+uPA) mice levels of adrenaline (males) and noradrenaline in the tumor and higher levels of adrenaline in the tumor and histamine in the skin in (-uPA) females.Conclusions. The uPA gene knockout limits the development of stress at the central regulatory level due to lower levels of A together with increasing serotoninergic mediation in the brain, as well as modulates the immune antitumor response due to higher levels of histamine in the tumor and 5 serotonin in the skin, as a result of lower monoamine oxidase activity, in mice with B16/F10 melanoma

    Aim. To study the levels of reduced and oxidized glutathione (GSH and GSSG, respectively), as well as the thiolΒ status in gastric cancer (GC) tumors of various histological types and grades.Materials and methods. The indicators were determined by ELISA methods in tumor, peritumoral and visuallyΒ intact tissues obtained during surgery from 52 patients with GC: 18 patients had a G1-2 adenocarcinoma (AC), 8Β with G3 AC, 6 with signet ring cell cancer (SRCC), 14 with combined gastric lesions (CGL) – AC with signet ringΒ cell fragments, 6 with patients with a component of undifferentiated cancer, G4.Results. In the groups of patients with low-differentiated and undifferentiated tumors, the GSH content in the tumorΒ tissue and the peritumoral zone was higher than in the group of patients with well- and moderately-differentiatedΒ tumors. Tumor GSH levels in G3 AC and SRCC exceeded the values in visually intact tissues. Moreover, in theΒ visually intact tissue of patients with SRCC, GSH level was reduced relative to G1-2 AC and CGL. GSH in allΒ tissues of patients with CGL was higher than in patients with G1-2 AC. The lowest level of GSSG in the tumorΒ tissue was registered in SRCC: 27.5% lower than in G1-2 AC and 30.3% lower than in G3 AC. Patients withΒ undifferentiated tumors (G4 AC) had the highest GSH content in all studied tissues: by 29.9% in tumor; by 40.7%Β in peritumoral zone; and in visually intact tissue not only GSH, but also GSSG was increased by 22.5–25.5% inΒ comparison with AC G1-2. G4 AC was also characterized by a sharp increase in the thiol status in tumor tissuesΒ by 80.2 and 89.9% higher than in visually intact and peritumoral tissues, and it was statistically higher than in ACΒ G1-2, AC G3, SRCC and CGL. The ratio of GSH and GSSG was the most informative.Conclusion. Poor AC differentiation (in the row G1-2, G3, G4) and a change of histological tumor type (AC, SPLΒ and SRCC), i.e. an increase in tumor aggressiveness, were accompanied by the enhancement of reductive processesΒ in tumor tissue, as evidenced by the statistically significant increase in the GSH/GSSG coefficient and a sharpΒ increase in the thiol status in G4 AC.ЦСль.

    The purpose of the study was to reveal special features of the Π’16/F10 melanoma growth in urokinase (uPA) geneΒ knockout mice with and without chronic neurogenic pain (CNP). Material and methods. The study included male andΒ female Π‘57Π’L/6 mice (n = 102) and C57BL/6-Plautm1.1BugThisPlauGFDhu/GFDhu mice with uPA gene knockoutΒ  (n = 48). Mice of the main subgroups underwent subcutaneous transplantation of Π’16/F10 melanoma 2 weeks afterΒ bilateral ligation of sciatic nerves (CNP model); mice of the same strain with standard melanoma transplantation servedΒ as controls. Results and discussion. Survival of uPA gene knockout mice did not differ from that of normal animals – 1.5 times higher in females than in males (p < 0.05), with melanoma onset in gene-deficient mice a week earlier. TheΒ dynamics of tumor growth had pronounced gender differences: in females, the tumor did not grow and its maximalΒ volume prior to death was 1.0 cm3, while tumors in males were characterized by an active growth with two peaks ofΒ volume increase (weeks 2 and 4). Melanoma was weakly metastatic – solitary metastases to the lungs (in females) orΒ no metastases, but pulmonary and heart hemorrhages were noted (in males). CNP decreased the survival of uPA geneΒ knockout females, as well as of normal animals, but did not influence the survival of males; primary tumors in genedeficientΒ mice appeared a few days later than in controls but their growth was more intense, with diminished genderΒ differences. Increased metastasis was manifested by the initiation of metastatic lesions to the lungs and liver in males,Β with maintained pulmonary hemorrhages, and by increased number of metastatic foci in the lungs together with theΒ appearance of pulmonary hemorrhages in females. Conclusions. The influence of uPA gene knockout on the courseΒ of Π’16/F10 melanoma differs in male and female mice. CNP enhances malignant tumor growth, diminishing genderΒ differences, and activates melanoma metastasis

    The purpose was to study the structural and functional parameters of erythrocyte membranes in the blood ofΒ patients with gastric cancer (GC) – adenocarcinoma, depending on its grade, signet ring cell carcinoma (SRCC),Β and combined gastric lesions (CGL).Materials and methods. The membrane fluidity in the area of the lipid bilayer and protein-lipid contacts, theΒ polarity of the lipid bilayer and the immersion of proteins in the lipid matrix of the membrane in red blood cellsΒ were evaluated by fluorimetry using the hydrophobic pyrene-based probe. The study included 86 patients withΒ GC divided into six groups: well- and moderately-differentiated adenocarcinoma (G1-2); poorly-differentiatedΒ adenocarcinoma (G3); SRCC; CGL and two groups of patients with a component of undifferentiated cancer: G4 +Β SRCC and G4 + G2-3. The results of the study were also analyzed in patients with serosal invasion and the spreadΒ to adjacent structures (T4 according to the TNM classification of malignant tumors) and in patients with stage IVΒ disease.Results. In all groups of GC patients, an increase in the membrane fluidity was observed. It was more pronouncedΒ in the zone of protein-lipid contacts, but it was also observed in the lipid bilayer. The membrane fluidity increasedΒ together with the grade of adenocarcinoma and was maximal when there were undifferentiated cells in stomachΒ tumors, reaching 93.8% in the zone of protein-lipid contacts and 54.1% in the lipid bilayer, compared with healthyΒ people (20 donors). An increase in the polarity of the lipid phase was also observed; it was most pronounced (byΒ 7–8%, p = 0.002–0.003) in adenocarcinoma patients with undifferentiated cells and with stage IV disease. A changeΒ in the immersion of proteins in the lipid matrix of erythrocytes was less characteristic of GC, compared with otherΒ cancers (breast, lung tumors, gynecological oncopathology, etc.).Conclusions. Changes in the structural and functional properties of erythrocyte membranes reflect the state of theΒ disease in patients with gastric cancer and may be important for predicting the course of the disease and the successΒ of treatment.ЦСль.

    Introduction. Cytochrome C in mitochondria transfers electrons from complex III to complex IV, and it is a signaling molecule in the apoptosis realization.The objective was to evaluate the level of cytochrome C in cell mitochondria in various organs of female mice with standard and stimulated growth of experimental B16/F10 melanoma.Methods and materials. The experiment was performed on female C57BL/6 mice (n=168). The groups were: intact animals (n=21); controls with a model of chronic neurogenic pain (CNP) (n = 21); group M β€” standard B16/F10 melanoma transplantation (n=63), group CNP + M β€” B16/F10 melanoma transplantation 3 weeks after CNP model creation (n=63). The level of cytochrome C (ng / mg protein) were measured by ELISA (Bioscience, Austria). Statistical analysis of results was performed using the Β«Statistica 10.0Β» program.Results. After 1 week of standard melanoma growth, an increase in the level of cytochrome C by 2.7 and 1.7 times was detected in mitochondria of the brain and liver; by the 3rd week, it decreased in the liver and skin by 1.7 times. In melanoma mitochondria, the level of cytochrome C was lower than in the skin of intact animals: by 2.5 times after week 1, by 4.5 times after week 2, and by 4.6 times after week 3. After 1 week of stimulated melanoma growth, the level of cytochrome C decreased compared control values: by 2.2 times in the brain, by 1.9 times in the liver, by 1.4 times in the skin; by week 3, it decreased by 4.8 times in mitochondria of the brain, by 4.7 times β€” in the liver, by 2.3 times β€” in the heart, by 1.9 times β€” in the skin. In melanoma mitochondria, the level of cytochrome C was lower than in the skin of intact animals: by 15.3 times after week 1, by 10.3 times after week 2, and by 8.8 times after week 3.Conclusion.

    Light-Induced Thiol Oxidation of Recoverin Affects Rhodopsin Desensitization

    The excessive light illumination of mammalian retina is known to induce oxidative stress and photoreceptor cell death linked to progression of age-related macular degeneration. The photochemical damage of photoreceptors is suggested to occur via two apoptotic pathways that involve either excessive rhodopsin activation or constitutive phototransduction, depending on the light intensity. Both pathways are dramatically activated in the absence of rhodopsin desensitization by GRK1. Previously, we have shown that moderate illumination (halogen lamp, 1,500 lx, 1–5 h) of mammalian eyes provokes disulfide dimerization of recoverin, a calcium-dependent regulator of GRK1. Here, we demonstrate under in vivo conditions that both moderate long-term (metal halide lamp, 2,500 lx, 14 h, rat model) and intense short-term (halogen lamp, 30,000 lx for 3 h, rabbit model) illumination of the mammalian retina are accompanied by accumulation of disulfide dimer of recoverin. Furthermore, in the second case we reveal alternatively oxidized derivatives of the protein, apparently including its monomer with sulfinic group. Histological data indicate that thiol oxidation of recoverin precedes apoptosis of photoreceptors. Both disulfide dimer and oxidized monomer (or oxidation mimicking C39D mutant) of recoverin exhibit lowered Ξ±-helical content and thermal stability of their apo-forms, as well as increased Ca2+ affinity. Meanwhile, the oxidized monomer and C39D mutant of recoverin demonstrate impaired ability to bind photoreceptor membranes and regulate GRK1, whereas disulfide dimer exhibits notably improved membrane binding and GRK1 inhibition in absence of Ca2+. The latter effect is expected to slow down rhodopsin desensitization in the light, thereby favoring support of the light-induced oxidative stress, ultimately leading to photoreceptor apoptosis. Overall, the intensity and duration of illumination of the retina affect thiol oxidation of recoverin likely contributing to propagation of the oxidative stress and photoreceptor damage

    The state of antioxidant system (the activity of catalase and ceruloplasmine), the intensity of chemiluminescence, and oxidative modification of proteins were studied in blood plasma of 61 patients with ovarian cancer (cystadenocarcinoma) III–IV stage in state of remission and ones with a local recurrent tumor. The dynamics of these indices was analyzed in dependence of recurrent tumor vascularization. The statistically significant changes of the activity of some links of antioxidant system were found, as well as chemiluminescence intensity increase in blood plasma. The level of oxidative modificated protein molecules was raised, the most expressed for products of the main character (530 nm). The dynamics of level of carbonyl derivatives of the neutral and main character (370 and 530 nm) was opposite directed during intensification of recurrent tumour vascularization and increase in speed of blood-groove in a recurrent tumorΠ£ 61 больной Ρ€Π°ΠΊΠΎΠΌ яичников (цистадСнокарцинома) III–IV стадий Π² состоянии рСмиссии ΠΈ с Π»ΠΎΠΊΠ°Π»ΡŒΠ½Ρ‹ΠΌ Ρ€Π΅Ρ†ΠΈΠ΄ΠΈΠ²ΠΎΠΌ ис- слСдованы Π² ΠΏΠ»Π°Π·ΠΌΠ΅ ΠΊΡ€ΠΎΠ²ΠΈ ΠΈΠ½Ρ‚Π΅Π½ΡΠΈΠ²Π½ΠΎΡΡ‚ΡŒ Ρ…Π΅ΠΌΠΈΠ»ΡŽΠΌΠΈΠ½Π΅ΡΡ†Π΅Π½Ρ†ΠΈΠΈ, состояниС ряда звСньСв антиоксидантной систСмы (Π°ΠΊΡ‚ΠΈΠ²Π½ΠΎΡΡ‚ΡŒ ΠΊΠ°Ρ‚Π°Π»Π°Π·Ρ‹, Ρ†Π΅Ρ€ΡƒΠ»ΠΎΠΏΠ»Π°Π·ΠΌΠΈΠ½Π°) ΠΈ ΡƒΡ€ΠΎΠ²Π΅Π½ΡŒ ΠΎΠΊΠΈΡΠ»ΠΈΡ‚Π΅Π»ΡŒΠ½ΠΎΠΉ ΠΌΠΎΠ΄ΠΈΡ„ΠΈΠΊΠ°Ρ†ΠΈΠΈ Π±Π΅Π»ΠΊΠΎΠ² общСпринятыми спСктрофотомСтричСскими ΠΌΠ΅Ρ‚ΠΎΠ΄Π°ΠΌΠΈ.
