Alterations of antitumor and metabolic responses in L5178Y-R lymphoma-bearing mice after only 30-minute daily chronic stress exposure [Text] / D. Caballero-Hernandez [та ін.] // Экспериментальная онкология. - 2017. - Т. 39, № 4. - С. 276-280. - Bibliogr. at the end of the art.

Annotation: In stress research, reducing times of stress induction may contribute to improving the well-being of experimental animals, especially in cancer models, already under physiological distress. To support this idea, we evaluated the effects of a short-timed stress protocol on endocrine, metabolic and immune indicators in mice bearing the L5178Y-R lymphoma. Materials and Methods: A 30-minute daily stress protocol was applied for 28 days to healthy and lymphoma-bearing BALB/c mice; body weight, plasma levels of corticosterone, norepinephrine, Th1/Th2 cytokines, insulin, and leptin, were measured. Results: We found a 12% significant decrease in body weight in non-tumor bearing mice under stress (p 0.007). The disruption of weight evolution was accompanied by a stress induced 85% decrease in plasmatic leptin (p 0.01) and total reduction of insulin. Tumor burden alone was associated to an increase in more than two-fold of plasmatic levels of norepinephrine (p 0.008). Neither stress nor tumor or their combination, resulted in an elevation of systemic IL-6. IFN-γ levels were 20 times higher in lymphoma-bearing animals when compared with non-tumor bearing mice (p 0.01); however, under stress, this response was reduced by half, indicating a suppressing effect of chronic stress on the antitumor immune response. Conclusion: A short-timed stress induction is enough to cause significant alterations in the metabolism and immunity of healthy and tumor-bearing mice, supporting the use of short-timed protocols as an efficient way to induce chronic stress that also considers concerns regarding the well-being of experimental animals in biomedical research

Assessment of the effect of wave device application on morphological changes in organs and cells of irradiated animals [Text] / V. Bebeshko, I. Homolyako, V. Grynchyshyn // Экспериментальная онкология. - 2017. - Т. 39, № 4. - С. 281-285. - Bibliogr. at the end of the art.

Annotation: To study the effect of the Device for wave influence on biological objects on the prevention of the development of acute radiation sickness and chronic radiation syndrome in vivo. Materials and Methods: The studies were performed on white rats irradiated at a dose of 8 Gy. The experimental group of irradiated rats was treated with a wave Device (Patent of Ukraine No. 53568) once, for 2.5 min, 1.5 h after irradiation. Their organs were processed by standard histologic methods. Results: In the demagnetized rats, dystrophic changes in cells and tissues of liver, lungs, kidneys, brain, bone marrow and spleen were insignificant in 60 days compared to the control non-demagnetized group of animals. Conclusion: The Device reduced the magnetic charge of magneto-containing elements and their compounds in the organism of the irradiated animals, and decreased the formation of reactive oxygen species, which play a key role in the development of radiation-induced diseases

The TGF-beta — SMAD pathway is inactivated in cronic lymphocytic leukemia cells [Text] / A. Matveeva [та ін.] // Экспериментальная онкология. - 2017. - Т. 39, № 4. - С. 286-290. - Bibliogr. at the end of the art.

Annotation: To study the status of the tumor growth factor beta (TGFB) pathway in chronic lymphocytic leukemia (CLL) cells and to uncover molecular details underlying CLL cell genesis. Objects and Methods: The study was conducted on peripheral blood samples of patients with CLL using the following methods: RNA isolation, analysis of expression of transcription factors using RT2 profiler assay, bioinformatics analysis of publicly available data bases on expression. Results: We have shown that the TGFB — SMAD canonical pathway is not active in CLL cells. SMAD-responsive genes, such as BCL2L1 (BCL-XL), CCND2 (Cyclin D2), and MYC, are down-regulated in CLL cells compared with peripheral blood B cells of healthy donors. Conclusions: The TGFB-mediated signaling is not active in CLL cells due to low (or absent) expression of SMAD1, -4, -5, -9, and ATF-3. Expression and phosphorylation status of SMAD2 and -3 should be further elucidated in the future studies

Stress during puberty facilitates precancerous prostate lesions in adult rats [Text] / D. Herrera-Covarrubias [та ін.] // Экспериментальная онкология. - 2017. - Т. 39, № 4. - С. 269-275. - Bibliogr. at the end of the art.

Annotation: Puberty can be a critical period for the long-term development of diseases, especially for stress-related disorders that depend on neuroendocrine and immune responses. Some organs like the prostate are prone to diseases that result from neuroendocrine or immune challenges, such as cancer. Aim: In the present study, we assessed the long-term effects of an acute pubertal stressor (immune-challenge) on the development of precancerous lesions in adult rats, and compared them with testosterone-induced prostatic lesions. Materials and Methods: Pubertal male rats received a single injection of lipopolysaccharide (LPS) or saline during puberty (5 weeks old). At adulthood (8 weeks old) males were subcutaneously implanted with either an empty capsule or filled with testosterone propionate (100 mg/kg). This resulted in a total of five groups: 1) intact untreated, 2) saline-treated and implanted with a blank capsule, 3) saline-treated and implanted with a testosterone capsule, 4) LPS-treated and implanted with a blank capsule, 5) LPS-treated and implanted with a testosterone capsule. Four weeks later, the rats were sacrified and their prostates processed for histology (hematoxylin and eosin stain) and blood serum processed for hormone analysis (testosterone and corticosterone). Results: Males treated with LPS (stressed during puberty via immune challenge) expressed epithelium dysplasia (specially in the ventral prostate), anisocytosis, presence of mononuclear cells, anisokariosis, non-basal polarity, abnormal nucleus-cytoplasm ratio, proplastic myoepithelium, and granular content in the lumen. These histological alterations were similar, but less severe than those observed in males implanted with testosterone during adulthood. Conclusion: These results indicate that pubertal exposure to an immune challenge (stress) facilitates the long-term development of prostatic lesions in adult male rats

TGF-β1 expression by glioma C6 cells in vitro [Text] / L. D. Liubich [та ін.] // Экспериментальная онкология. - 2017. - Т. 39, № 4. - С. 258-263. - Bibliogr. at the end of the art.

Annotation: The aim of the work was to study the impact of fetal rat brain cell supernatant (FRBCS) on the expression of transforming growth factor β1 (TGF-β1) and p53 in C6 cells of rat glioma in vitro. Materials and Methods: FRBCS was obtained from suspensions of fetal rat brain cells on the 14th (E14) day of gestation. C6 glioma cells were cultured for 48 h in the presence of FRBCS or FRBCS + anti-TGF-β1 monoclonal antibody. Immunocytochemical staining for TGF-β1 and p53 was performed. Results: The proportion of TGF-β1-immunopositive tumor cells in C6 glioma cultures was statistically significantly higher than in the control cell cultures of normal fetal rat brain. FRBCS reduced the proportion of TGF-β1-immunopositive tumor cells and increased the proportion of p53-immunopositive cells in C6 glioma cultures. In cells cultured with FRBCS + anti-TGF-β1 monoclonal antibody, the above effects of FRBCS were abrogated. Conclusion: The obtained results suggest that TGF-β1 seems to be responsible for decrease in TGF-β1 expression and increase in p53 expression in C6 glioma cells treated with FRBCS

Cytotoxic activity of metformin in vitro does not correlate with its antitumor action in vivo [Text] / O. N. Pyaskovskaya [та ін.] // Экспериментальная онкология. - 2017. - Т. 39, № 4. - С. 264-268. - Bibliogr. at the end of the art.

Annotation: It is known that metformin is a hypoglycemic drug used to treat type II diabetes mellitus. Recently active studies of its antitumor activity in relation to different types of malignant cells are conducted. Aim: To determine the relationship between cytotoxic activity of metformin in vitro and its antitumor activity in vivo. Materials and Methods: The rat C6 glioma cell line and mouse Lewis lung carcinoma cells (LLC) were used in this work. The number of living cells in the cytotoxic test was evaluated using sulforhodamine B. Parameters of tumor cell susceptibility to metformin activity in vitro were calculated using nonlinear and linear regression of experimental data. The antitumor action of metformin in vivo was evaluated routinely by the extension of survival time (ST) (in rats with intracerebral C6 glioma) and its effect on the volume of the primary tumor, the number and volume of metastases (in mice with LLC). Results: In cultured LLC cells in vitro, the proportions of metformin-resistant (A₁, %) and metformin-sensitive (A₂, %) subpopulations were 10.0 ± 2.2% and 92.0 ± 3.5%, respectively, in terms of the total number of living cells. Parameter t, which characterizes the sensitivity of cancer cells to metformin action (the lower is the value of this parameter the higher is sensitivity of cells to metformin cytotoxicity), for metformin-resistant and metformin-sensitive subpopulations was: t1(mM) = ∞ and t2(mM) = 2.9 ± 0.3, correspondingly. For metformin-sensitive subpopulation of LLC cells IC₅₀ (mM) = 2.42 ± 0.34. The volume of the primary tumor, the amount and volume of metastases in mice receiving metformin at a dose of Dmin (0.15 g/kg) and Dmax (0.3 g/kg) values did not significantly differ from those in the control. However, in the case of Dmin, there was a tendency to increased volume of the primary tumor, in the case of Dmax, there was a tendency to increased volume of metastases. The analogical parameters (A₁, A₂, b₁, b₂, IC₅₀ (1), IC₅₀ (2)) characterizing cell sensitivity to the action of metformin in vitro were obtained in relation to C6 glioma cells. In metformin-resistant subpopulation, these parameters were: A₁ (%) = 72.3 ± 1.4; b1 (%/mM) = 0.43 ± 0.005; IC₅₀ (1) (mM) = 84.1 ± 2.4. For metformin-sensitive subpopulation, these parameters were: A₂ (%) = 30.8 ± 2.3; b2 (%/mM) = 2.87 ± 0.4; IC₅₀ (2) (mM) = 5.37 ± 0.45. In vivo, a statistically significant anti-glioma effect of metformin was observed: at a dose of Dmax (5.2 g/kg) administration of this preparation resulted in a prolongation of the mean ST of tumor-bearing rats by 23% (p 0.05) compared with that in the control. Conclusions: We found no correlation between the cytotoxic/cytostatic action of metformin in vitro and its antitumor activity in vivo on the two types of tumor cells; these results indicate a significant contribution of the tumor microenvironment to the implementation of the antitumor activity of the drug

Phenotypic features of endometrial tumors in patients with family history of cancer [Text] / L. G. Buchynska [та ін.] // Экспериментальная онкология. - 2017. - Т. 39, № 4. - С. 312-318. - Bibliogr. at the end of the art.

Annotation: To determine the peculiarities of expression of a number of proteins-regulators of the cell cycle in endometrial cancer (EC) cells in patients with a family history of oncological pathologies. Patients and Methods: 95 EC patients (stage І–ІІ) were included into the study. Clinical-genealogical analysis was performed. 54 patients (group I) had healthy relatives, and in families of 41 patients (group II) an aggregation of malignant tumors of different genesis (mainly tumors of the gastrointestinal tract and the female reproductive system) was recorded. p53, р21WAF1/CIP1, р16INK4a, and Ki-67 were assessed immunohistochemically in the surgical samples. Results: In the majority of patients, both from group I and II, moderately differentiated tumors were observed (in 38.9 and 46.3% of cases, respectively), mainly with deep myometrium invasion (64.8 and 58.5% of cases, respectively). In EC patients from group II, a significantly higher number of р16INK4a-positive cells (17.7 ± 1.7%; p = 0.001) and lower number of p53-positive (30.9 ± 3.2%; p = 0.05) and Ki-67-positive (26.9 ± 2.7%; p = 0.048) cells was observed compared to those in tumors of patients from group I (12.0 ± 1.6; 37.7 ± 2.8 and 36.7 ± 3.4%, respectively). Conclusion: Phenotypic features of the EC in the patients with family history of cancer differ from those in tumors of patients without such aggregation. The biological heterogeneity of EC seems to relate to the oncogenealogical history of patients. Also this biological heterogeneity is linked to the molecular features of EC cells, which affects cancer aggressiveness and the course of the disease

Annotation: A 42-year-old hypothyroid shepherd presented with a progressive abdominal lump accompanied by nausea and abdominal fullness. In addition, he had worsening hypothyroidism, despite supranormal doses of thyroxine. Computed tomography of the abdomen was suggestive of a mass lesion in relation to the stomach. A resection of the mass was done and the histopathology was suggestive of gastrointestinal stromal tumor. After surgery, the patient became euthyroid. We believe the patient had consumptive hypothyroidism due to the tumor
