BACKGROUND Cervical carcinomas are second most frequent type of women cancer. Success in diagnostics of this disease is due to the use of Pap-test (cytological smear analysis). However Pap-test gives significant portion of both false-positive and false-negative conclusions. Amendments of the diagnostic procedure are desirable. Aetiological role of(More)
BACKGROUND High risk type human papilloma viruses (HR-HPV) induce carcinomas of the uterine cervix by expressing viral oncogenes E6 and E7. Oncogene E7 of HR-HPV disrupts the pRb/E2F interaction, which negatively regulates the S phase entry. Expression of tumor suppressor p16ink4a drastically increases in majority of HR-HPV associated carcinomas due to(More)
BACKGROUND The presence of human cytomegalovirus (HCMV) in male genital tract suggests its vertical transmission with spermatozoa and the development of a potentially dangerous fetal infection. The objective of the present study was to evaluate the possibility of intracellular HCMV localization in male germ cells and to examine the effect of the virus on(More)
Medical histories of 101 urothelial bladder cancer patients were compared with the results of morphological analysis and biomolecular detection of human papilloma viruses (HPV) in the tumor specimens. DNA of HPV16 (the major type of virus responsible for appearance of cervical carcinoma) was detected in 38 specimens, while mRNA of E6 and E7 oncogenes and E7(More)
Destruction of the connective tissue matrix (CTM) and angiogenesis are the two processes playing a key role in tumor progression. Matrix metalloproteinases (MMPs) play a leading role in processes of tissue destruction. Tissue collagenases MMP-1 and MT1-MMP hydrolyze fibrillar collagens constituting the base of CTM and enable tumor invasion. Gelatinases A(More)
Tumor-associated protein survivin is a bifunctional protein that can participate either in the regulation of cell division or in the inhibition of apoptosis depending on its location in the cell and its structural state. The aim of the present work was to obtain monospecific antibodies to survivin targeting various sites in the protein and suitable for the(More)
