Predictive value of MMP-2, MMP-9, TIMP-1 in surgical treatment of localized renal cell cancer

Purpose of the study. To determine the association of individual biomolecular markers of oncogenesis MMP‑2, MMP‑9 and the inhibitor of metalloproteinases TIMP‑1 with the risk of tumor invasion and metastasis in the early and late postoperative period in various types of surgical treatment of RCC.Materials and methods. The study prospectively included medical data of 60 patients with kidney cancer with T1-3N0 M0 who received surgical treatment at the Urology Clinic of the S.R.Mirotvortsev Design Bureau of the SSMU from 2016 to 2019. The patients were divided into 3 groups: 1st group included 20 patients who underwent kidney resection for elective indications, with tumors of the renal parenchyma; 2nd group – 20 patients who underwent radical nephrectomy by laparoscopic approach; Group 3-20 patients who underwent radical nephrectomy with lumbotomy access. All patients being in the early (7-10th day) and long-term postoperative period (after 1 and 2 years) by solid-phase ELISA, on a StatFax 4200 analyzer using eBiosence and Cloud-Clone Corp reagent kits, a study was made on the basis of the concentration in the blood serum of markers of oncogenesis MMP‑2, MMP‑9 and TIMP‑1 metalloproteinase inhibitor.Results. In all groups of patients with RCC, an initial increase in the concentration of MMP‑9 was revealed compared to the control (p≤0.05). According to the results of the ROC analysis, this indicator has a high specificity and sensitivity in terms of predicting RCC at the preoperative stage. The highest sensitivity and specificity for detecting tumor progression was demonstrated by matrix metalloproteinases: MMP‑2 – sensitivity 96 %, specificity 67 % (cut-off point 357.5 pg/ml) and MMP‑9 – sensitivity 87.5 % and specificity 62 % (cut-off point 958 ng/ml). At the same time, TIMP‑1 showed less significant indicators – sensitivity and specificity (74 % and 60 %, respectively) with a cut-off point of 0.49 ng/ml.Conclusion. Serum MMP‑2 and MMP‑9 are a marker of a poor prognosis for the progression of RCC. Elevated levels of MMP‑9 in the blood serum of RCC patients before and after various types of surgical treatment reflect the individual characteristics of the patient’s body and the tumor process. Dynamic monitoring of the level of markers of oncogenesis in patients with RCC allows a personalized approach to the choice of the scope and method of surgical treatment of RCC.

Scientific search under the pressure of high responsibility: development of the technology of electromagnetic isotope separation in the framework of the USSR Atomic project

One of the ways to obtain nuclear explosives for the manufacture of the first atomic bombs was the separation of uranium isotopes by electromagnetic (mass spectrographic) method. The theoretical justification and experimental separation of uranium isotopes by this method was carried out by L. A. Artsimovich in the Laboratory No. 2 of the USSR Academy of Sciences. By the middle of 1945, L. A. Artsimovich had obtained results at the experimental facility indicating the possibility of stable enrichment of uranium with the U-235 isotope using this method. Having the results of the experiments, the Design Bureau at the “Electrosila” plant (D. V. Efremov), with the participation of the Research Vacuum Institute (S. A. Vekshinsky) and the “A” Institute (M. Ardenne), developed a project of an industrial multi-chamber installation for electromagnetic separation of uranium isotopes SU-20. Such an installation was manufactured and put into operation at the newly created plant in the Urals, which allowed in 1951 to obtain the necessary amount of uranium-235 for the RDS-3 atomic bomb. After 1952, the technology of electromagnetic separation was no more used for the separation of uranium isotopes due to the improvement of more productive equipment for gas-diffusion separation of isotopes. The equipment of the electromagnetic isotope separation plant built in the Urals was used to produce lithium-6, needed to equip the first thermonuclear charge, which was successfully tested in 1953. In the next years, the electromagnetic isotope separation plant was involved in the manufacture of isotope products for scientific, technical and medical applications at wide range of utilization in Russia and abroad.
