Inzulinu podobné a jiné růstové faktory a nádory Insulin like and other growth factors and tumors Disertační práce Plzeň 2011 Mgr. Radek Kučera Summary The interaction between growth factors and cancer incidence and development has been discussed recently. First works suggesting possible connection between increased production of insulin like growth factors with an increased incidence of tumors came already from early 80s of the last century. The aim of my work was focused on evaluation of possible relation between insulin like growth factors or their binding proteins and tumors from different perspectives, to assess their significance and try to determine what role the IGFs and IGFBPs may play in the current tumor diagnostics. The work itself is divided into two parts, the theoretical and practical ones. In the theoretical part, I summarized the action of IGF in human body and also focused on previous findings on the role of IGF system in cancer diagnoses. In the practical part, divided into three subsections, I focused on investigation of relations in a large set of patients with different cancer diagnoses, in a group of women with breast cancer and, finally, I focused on changes of IGF1 levels during follow-up. Theoretical part Insulin-like growth factors (IGF) are peptides, that participate on growth...

Identification of biomarkers involved in the pathophysiology of gestational diabetes mellitus ABSTRACT Gestational diabetes mellitus is a disorder of glucose metabolism that occurs in pregnancy and resolves after delivery. Increasing production of pregnancy-related hormones leads to insulin resistance which is not adequately compensated by increased insulin secretion. Since obesity is an important risk factor for gestational diabetes and is also associated with adipose tissue dysfunction and increased peripheral insulin resistance, the question arises as to what extent is the adipose tissue involved in the development of gestational diabetes. The first part of the thesis focuses on the identification of changes in plasma concentration and mRNA expression of adipokines fetuin A, fetuin B and FGF21. In our study we did not show that the presence of gestational diabetes significantly influenced the plasma concentration of fetuin A, fetuin B and FGF21 during pregnancy. An important finding was that women who had pregnancy complicated with gestational diabetes had a significantly higher concentration of FGF21 several months after delivery in comparison to healthy pregnant women. We have been able to demonstrate the production of fetuin A in the placenta and fetuin B in perineal and subcutaneous tissue. However,...
