Summary:

Restoration and regeneration of tissues are complex processes involving a large number of signaling mechanisms. In this study possible mechanisms of angiogenesis during tissue regeneration are presented. One of these mechanisms is the creation of a new capillary layer by angiogenesis. Previously it was believed that high and rapid levels of capillary growth are necessary for optimal healing of tissues. But several studies have demonstrated that a period of vascular regression occurs after the growth of blood vessels in a wound, and the number of the newly formed vessels decreases until the number of the blood vessels is equal to the density of the vascular network in the intact tissue. Reduced inflammation and angiogenesis are features of optimal healing.

The prospects for application of biomarker "vascular endothelial growth factor" in predicting the treatment outcomes of bladder cancer

Year: 2018, volume 14 Issue: №2 Pages: 268-272
Heading: Urology Article type: Original article
Authors: Zakharova N.B., Ponukalin A.N., Skriptsova S.A.
Organization: Saratov State Medical University
Summary:

Purpose: assessment of the diagnostic value of Vascular Endothelial Growth Factor (VEGF) in predicting the outcome treatment of patients with muscle-invasive bladder cancer. Material and Methods. The study involved 264 people: 204 patients with RMP; 60 people aged 21 to 60 years were the comparison group. Patients with RMP are divided into stages of the disease. With non-muscle-invasive ВС (NIRMP) under TA-1NxMo there were 75 patients. Out of 129 patients with muscle-invasive ВС (MIRE) within the body (pT2aN0M0-T2bN0M0) was diagnosed in 69 of people. In 60 patients, the tumor sprouted paravesical tissue and surrounding organs (rt3a-bn0m0-41; pT36N1M0-11; pT4N1M0-5; T4N1M1-3); 19 patients had metastases to the iliac lymph nodes are installed only after the operation. Metastases were found in three patients out of 19 in addition to the lymphonoduses in the lungs. Tumors had the following gradations: G1-97; G2-37; G3-58. All patients NMIN (n=75) completed a TUR of the bladder wall with the tumor. MERE patients underwent radical cystectomy (n=117), open resection of the bladder (n=12), palliative surgery (n=3). The period of follow-up after surgical treatment was 3.5±0.5years. Quantitative determination of VEGF in blood serum was performed by solid-phase ELISA. Results. Despite the fact that the increase in VEGF level of blood serum in groups of patients with NIMRE and MIRE has significant differences both before and in the postoperative period, it is associated with the aggressiveness of tumor growth, development of metastases and recurrences of the disease. Conclusion. The increase in the content of VEGF serum suitable for use as an indicator: the risk of relapse within the first year after TUR in patients NMIN; development of relapses and metastases in pre and postoperative periods in MERE patients.

Immunopathogenetic mechanisms of skin toxic response of antitumor therapy with mul-tikinase of angiogenesis inhibitors

Year: 2017, volume 13 Issue: №3 Pages: 605-611
Heading: Dermatovenerology Article type: Review
Authors: Shatokhina Е.А., Kruglova L.S.

Summary:

The violation of the angiogenesis is associated with pathogenesis of many diseases, but especially pronounced pathological angiogenesis underlies the growth of tumors and metastasis. The physiological control of the angiogenesis is carried out by many growth factors, one main factor — the vascular endothelial growth factor (VEGF), realizing their effects by receptors — proteinkinases. The target therapy of various neoplastic diseases, based on the suppression of angiogenesis, aimed at blockade of receptors for VEGF and other pro-angiogenic growth factors. However, the medicine blockade of receptors for growth factors and suppression of tumor angiogenesis leads to inappropriate exposure are the main cells of the dermis — fibroblasts. As a result of changing the regulatory mechanisms of inhibition of the physiological renewal of epidermis, suppression of angiogenesis and repair when damaged skin there are various skin toxic reactions that are dependent on receptor targets of angiogenesis inhibitors. The study of the mechanisms of adverse events of targeted therapy is an important way of oncoimmunology and dermatology, which will further help to determine the optimal scheme of correction of dermal toxicity and maximize the effectiveness of the antitumor therapy.

The diagnostic importance of biomarkers of angio-genesis and inflammation at patients with prostate diseases

Year: 2016, volume 12 Issue: №4 Pages: 593-598
Heading: Urology Article type: Original article

Organization: Saratov State Medical University
Summary:

Purpose: to establish the nature of change of the maintenance of PSA and markers of angiogenesis and inflammation in blood serum at patients with prostate diseases. Material and Methods. 72 patients with the level of the general PSA more than 4 ju/ml were examined. The first group of patients with benign prostatic hyperplasia with histology conclusion and with benign prostatic hyperplasia and prostatic intraepithelial neoplasia of low degree included 29 patients, the second group consisted of 9 patients with prostatic intraepithelial neoplasia of high degree, the third group included 5 patients with the localized prostate cancer, the fourth group consisted of 25 patients with locally advanced prostate cancer, and the fifth group with 6 metastatic prostate cancer patients. Results. At patients with prostate diseases the rise of VEGF level in blood serum occurs with increase of the maintenance of PSA and develops at the precancer stage (the prostatic intraepithelial neoplasia of high degree) and against high concentration of biomarkers of inflammation. Determination of VEGF concentration in blood serum at patients with "a gray zone" of PSA may have clinical value at the personified maintaining of patients with prostate cancer at the stage of pre-biopsy diagnostics. Conclusion. The simultaneous increase of the VEGF content in blood serum and the general PSA at prostate cancer patients is one of characteristics of a progression of tumoral growth.

Organization: Saratov State Medical University
Summary:

Aims. The study was aimed to identify relationships of immune disorders and angiogenesis in patients at different stages of rosacea. Materials and methods. We examined 110 patients with rosacea. The diagnosis was based on diagnostic criteria. We summarized the role of predictors in the development of rosacea. We investigated pro- and anti-infammatory cytokines, vascular endothelial growth actor (VEGF), fbroblast growth factor (FGF) for the detection of immune disorders and angiogenesis. Results. The immune response in patients with rosacea was of mixed Th-1 and Th-2 type which can be markers of chronic autoimmune infammation. Simultaneously with the change in cytokine profle we revealed activation of angiogenesis (high levels of VEGF, FGF).

Vascular endothelial growth factor as a marker of development of relapses in the postoperative period in kidney and bladder tumors

Year: 2011, volume 7 Issue: №3 Pages: 711-714
Heading: Urology Article type: Original article
Authors: Durnov D.A., Mikhailov V. Yu., Zakharova N.B., Ponukalin A.N.
Organization: Saratov State Medical University
Summary:

Aim: The article considers the results of research of the vascular endothelial growth factor (VEGF) in blood serum in patients with kidney and bladder tumors after surgical intervention. Materials and methods: The total of investigated patients consisted of 75 primary patients with kidney cancer (stages pT1-pT3N0M0), 75 patients with non-muscle-invasive bladder cancer (NMIBC), stages pTa-1NxMoG1-3, 25 patients with cysts of kidneys and 30 healthy patients. Results of research of content of VEGF in patients with kidney cancer and NMIBC in the postoperative period confirmed the role of angiogenesis processes both in the development of tumoral tissue and relapses of disease. Conclusion: Investigations of VEGF in blood serum may be additional method of revealing kidney cancer and NMIBC after surgical treatment of relapses of disease and may influence on the duration of recurrence-free period
