Understanding the cellular pathways that regulate angiogenesis during hypoxia is a necessary aspect in the development of novel treatments for cardiovascular disorders. Although the pathways of angiogenesis have been extensively studied, there is limited information on the role of miRNAs in this process. miRNAs or their antagomirs could be used in future therapeutic approaches to regulate hypoxia-induced...
To compare Color Doppler sonography with immunohistochemical microvessel density and Bcl-2 assessement in women with benign and malignant adnexal tumors we examined 112 women with adnexal tumors with the use color Doppler sonography (B&K 2002 ADI and GE Voluson 730 scanners) performed before the surgical procedure. Histological type, grading, FIGO stage and menopausal status were compared with...
Carbon monoxide (CO) is an odorless, tasteless and colorless gas which is generated by heme oxygenase enzymes (HOs). HOs degrade heme releasing equimolar amounts of CO, iron and biliverdin, which is subsequently reduced to bilirubin. CO shares many properties with nitric oxide (NO), an established cellular messenger. Both CO and NO are involved in neural transmission and modulation of blood vessel...
Gene transfer and antisense therapy offer novel approaches to the study and treatment of vascular diseases. The localized nature of vascular diseases like restenosis has made the application of genetic material an attractive therapeutic option. Viral and nonviral vectors have been developed to facilitate the entry of foreign DNA or RNA into cells. Vector improvement and production, demonstration...
