Protein carbonylation as a mechanism of regulation of MCF-7 breast cancer cell proliferation
Tumor progression is accompanied by dysregulation of cell proliferation and apoptosis, which plays an essential role in breast cancer pathogenesis and cell resistance to chemotherapy. The role of protein carbonylation in molecular mechanisms of regulating MCF-7 breast cancer cell proliferation under the effect of roscovitine, a selective inhibitor of cyclin-dependent kinases, was evaluated. The cells were grown in adherent cell culture with or without roscovitine. The levels of reduced/oxidized glutathione and the concentration of protein carbonyl derivatives were determined by spectrophotometry. The cell cycle was evaluated by the flow cytometry; the same technique was used to measure the reactive oxygen species (ROS) concentration. Cell culture with roscovitine resulted in a decrease in the redox potential of the glutathione system and a rise in the ROS and protein carbonyl derivative concentrations. Roscovitine contributed to the G0/G1 and G2/Π phase arrest due to its interaction with ATP-binding sites of cyclin-dependent kinases. Roscovitine could also promote enzyme carbonylation. The obtained results can be further used for development of personalized approaches to breast cancer therapy

Introduction. High rates of cancer incidence and mortality worldwide dictate the necessity of developing new methodological approaches in understanding the molecular mechanisms of cancer progression associated with intracellular redox regulation imbalance.The objective of the study was to evaluate the role of protein carbonylation in regulating breast cancer cell proliferation under redox status modulation.Materials and Methods. In the intact breast cancer cells and in the cells cultured under redox status modulation using 5mM N-ethylmaleimide (an - SH group blocker) and 5 Mm 1,4-dithioerythritol (a thiol group protector), the concentration of thioredoxin and its carbonylated form was measured using Western blot analysis. The activity of thioredoxin reductase and the level of protein carbonyl derivatives were determined using spectrophotometry. Cell cycle phase distribution was evaluated by flow cytometry.Results and Discussion. Under the effect of N-ethylmaleimide, cell cycle arrest in the S-phase was confirmed by oxidative modification of proteins, including thioredoxin carbonylation. When culturing MCF-7 cells in the presence of 1,4-dithioerythritol, cell cycle arrest in the G0/G1 phases was associated with a rise in the concentrations of reduced thioredoxin and glutathione forms.Conclusion. The thioredoxin system and oxidative modification of proteins are involved in redox-dependent modulation of breast cancer cell proliferation. Studies in the area of redox proteomics offer great potential to seek molecular targets of malignant transformation of breast cells.ΠΠ²Π΅Π΄Π΅Π½ΠΈΠ΅.

Relevance. Impairment of apoptosis regulation in P19 cells is correlated with generation of oxidative stress. UnderΒ hypoxia, changes in mitochondrial functions occur, which may exacerbate oxidative stress in the tumor cell.Β The aim of the study was to evaluate the effects of N-ethylmaleimide and 1,4-dithioerythritol on implementationΒ and regulation of apoptosis in P19 cells under hypoxia in vitro.Materials and methods. P19 cells (mouse teratocarcinoma) cultured under hypoxia served as the material for theΒ study. For redox status modulation, 5mM N-ethylmaleimide and 1,4-dithioerythritol in the final concentrations ofΒ 5 mM were used. The intracellular concentration of calcium ions, the transmembrane potential and the number ofΒ Annexin V, CD95 and CD120 positive cells were determined by flow cytometry. The levels of reduced, oxidizedΒ and protein-bound glutathione, protein SH groups, hydroxyl radical and protein carbonyl derivatives were measuredΒ by spectrophotometry.Results. The alteration in the redox status of the glutathione system under hypoxia, accompanied by oxidativeΒ modification of proteins (glutathionylation and carbonylation), influences the metabolism in the tumor cell onΒ the whole. Under the effects of 1,4-dithioerythritol, an SH group protector, this alteration promotes formation ofΒ additional mechanisms to escape apoptosis, whereas under the effects of N-ethylmaleimide, an SH group blocker,Β it, on the contrary, promotes apoptosis activation.Conclusions. The changes in the redox homeostasis of the tumor cell and modulation of oxidative modificationΒ of proteins (glutathionylation and carbonylation) under hypoxia are one of the promising approaches to targetedΒ regulation of cell death.ΠΠΊΡΡΠ°Π»ΡΠ½ΠΎΡΡΡ.

The objective is to compare clinical symptoms, lipid peroxidation indicators, the state of the antioxidant system and assess their impact on the severity and progression of pseudotuberculosis in children.Materials and methods. We examined 125 children with pseudotuberculosis divided into 4 groups according to the severity and nature of the disease progression and 45 healthy children. The material for the study was red blood cells and blood plasma of patients received in the dynamics β the acute period (during hospitalization); 3-4 weeks later β the phase of early convalescence with a non-smooth progression and moderate and heavy severity; the recovery period with a smooth progression and mild and moderate severity; 5-6 weeks later β the recovery period with a non-smooth progression and moderate and heavy severity. The spectrophotometric method was used to study lipid peroxidation (the concentration of diene conjugates, TBA-reactive substances) in the blood plasma and components of the antioxidant support system (the content of reduced glutathione; the activity of glutathione reductase, glutathione peroxidase, and catalase) in red blood cells.Results. It was determined that moderate and heavy pseudotuberculosis forms prevail in hospitalized children, the disease progression in 35.2% of them was non-smooth; lipid peroxidation products accumulate in the blood plasma and the concentration of reduced glutathione decreases in red blood cells during the acute period of pseudotuberculosis in all children relative to the parameters in the control group. In the period of early convalescence an imbalance in the functioning of antioxidant enzymes of red blood cells, as well as the accumulation of TBA-reactive substances and a decrease in the content of reduced glutathione were observed in patients with moderate and heavy pseudotuberculosis.Conclusion. The impact of the imbalance of pro-/antioxidants on the formation of predominantly moderate and heavy pseudotuberculosis in children is shown. Prognostic criteria for the development of a non-smooth progression of pseudotuberculosis are a high level of lipid peroxidation products in the blood plasma, no normalization in values of glutathioneΒ system components and the activity of erythrocyte catalase during early convalescence.Β Π¦Π΅Π»Ρ: ΡΠΎΠΏΠΎΡΡΠ°Π²ΠΈΡΡ ΠΊΠ»ΠΈΠ½ΠΈΡΠ΅ΡΠΊΠΈΠ΅ ΡΠΈΠΌΠΏΡΠΎΠΌΡ, ΠΏΠΎΠΊΠ°Π·Π°ΡΠ΅Π»ΠΈ ΠΏΠ΅ΡΠ΅ΠΊΠΈΡΠ½ΠΎΠ³ΠΎ ΠΎΠΊΠΈΡΠ»Π΅Π½ΠΈΡ Π»ΠΈΠΏΠΈΠ΄ΠΎΠ², ΡΠΎΡΡΠΎΡΠ½ΠΈΡ Π°Π½ΡΠΈΠΎΠΊΡΠΈΠ΄Π°Π½ΡΠ½ΠΎΠΉ ΡΠΈΡΡΠ΅ΠΌΡ ΠΈ ΠΎΡΠ΅Π½ΠΈΡΡ ΠΈΡ

Introduction. One of the crucial tasks in medicine is studying the molecular mechanisms of selective management of tumor cell apoptosis following conformational changes in protein molecules (ubiquitination).The purpose of the study. The aim of the project is to establish the role of ubiquitin and ubiquitinligase in dexamethasone-induced apoptosis in Jurkat cells.Materials and methods. The study was carried out on the Jurkat tumor cell line (intact cells and cells cultured in the presence of an apoptosis inducer dexamethasone in the final concentration of 10 Β΅mol. In intact and dexamethasone-affected Jurkat cells, implementation of apoptosis and the amount of FAS-, TNF Receptor 1 and cells with reduced mitochondrial membrane potential were assessed by flow cytometry using FITC-conjugated Annexin V and Propidium Iodide. The levels of NF-ΞΊB, Apaf-1, ubiquitin and ubiquitin ligase were determined by Western blot analysis. The activity of caspase-3 was measured by spectrofluorometry.Results. When adding the apoptosis inducer dexamethasone to the Jurkat cell culture, we registered a fall in the concentration of ubiquitin and a rise in the level of ubiquitinligase against the backdrop of activated receptor(an increase in the amount of Annexin V positive cells, FASand TNF Receptor 1) and mitochondrialmediated (an increase in the number of cells with reduced mitochondrial membrane potential and elevation of Apaf-1 level) pathways of apoptosis, as opposed to the intact cell culture. We estimated the completion of apoptosis by determining the activity of caspase-3 in the investigated tumor cells.Conclusion. The obtained findings allow the conclusion that ubiquitination of regulatory and effector proteins in programmed cell death is one of the molecular mechanisms that regulates and selectively controls apoptosis in Jurkat cells.ΠΠΊΡΡΠ°Π»ΡΠ½ΠΎΡΡΡ.

Introduction. Changes in the redox status of tumor cells can be used as one of the molecular mechanisms of apoptosis aimed at increasing the susceptibility of tumor cells to chemotherapeutic agents. Purpose: to study the mechanisms of dysregulation of apoptosis in P19 tumor cells under the conditions of redox status modulation. Material and methods. Apoptosis in P19 tumor cells was assessed by flow cytometry analysis. The number of annexin-positive cells, the expression of CD95 and CD120, as well as the intracellular calcium ion concentration and the percentage of cells with reduced mitochondrial transmembrane potential were measured. The protein-glutathione mixed-disulfide level and the GSH/GSSG ratio were determined by spectrophotometry. To modulate redox status of cells, the protector and blocker of SH-groups, or N-acetylcysteine were used. Results. Incubation of cultures in the presence of SH-group blocker resulted in the imbalance in the glutathione system with increased concentration of glutathionylated proteins. A decreased redox status led to an increased CD95 and CD120 expression levels on the membrane of P19 tumor cells, as well as to decreased mitochondrial potential and increased intracellular calcium ion concentration, thus contributing to the launch of a P19 tumor cells. The presence of SH-group blocker and N-acetylcysteine resulted in an increased number of annexinpositive cells. Conclusion. Along with the development of oxidative stress, the molecular redox-dependent mechanisms of apoptosis dysregulation through the mitochondrial and receptor-mediated pathways were identified in the P19 tumor cells.ΠΠ²Π΅Π΄Π΅Π½ΠΈΠ΅.
