Cisplatin and doxorubicin are widely used anticancer drugs that cause DNA damage, which activates the ATM-Chk2-p53 pathway in cancer cells. This activation leads to cell cycle block or apoptosis, depending on the nature of the DNA damage. In an attempt to enhance the effects of these agents, we inhibited ATM/ATR and Chk2, which are known upstream regulators(More)
If diagnosed at early stages, patients with hepatocellular carcinoma (HCC) can receive curative therapies, whereas therapeutic options at later stages are very limited. Here, we addressed the potential of soluble Axl (sAxl) as a biomarker of early HCC by analyzing levels of sAxl in 311 HCC and 237 control serum samples from centers in Europe and China.(More)
With the recent addition of anti-angiogenic agents to cancer treatment, the angiogenesis regulators in platelets are gaining importance. Platelet factor 4 (PF-4/CXCL4) and Connective tissue activating peptide III (CTAP-III) are two platelet-associated chemokines that modulate tumor angiogenesis, inflammation within the tumor microenvironment, and in turn(More)
Vitamin D deficiency has been implicated in the epidemiology of common malignancies including colorectal cancer. We studied consecutive blood levels of 25-hydroxycholecalciferol (25-OHD) in relation to other clinical and laboratory variables in metastatic colorectal cancer patients to ascertain whether their variations may be prognostic or predictive(More)
Vitamin D is an endogenous product of mammalian organisms from which an active agent of a steroid hormone nature is synthesized. These hormones participate in a variety of key metabolic processes in every nuclear cell, whether on endocrine, paracrine and autocrine or subcellular level. Vitamin D represents a very interesting molecule which participates in a(More)
With the development and subsequent clinical applications of anticancer immuno-and angiomodulatory therapies and expanded knowledge on significance of tumor microenvironment for disease prognosis and treatment outcome, a classical blood analyte, lactate dehydrogenase (LDH), gains in importance as a tumor marker reflecting to some extent immunosupressive and(More)
Cancer cells trigger platelet aggregation. Reciprocally, platelet aggregation promotes tumor growth and metastasis. Within the tumor microenvironment, platelet regulates tumor growth via several mechanisms involving stimulation of angiogenesis, inflammation, coagulation, and stabilizing of vessel wall. In circulation, cancer cells coated by platelets can(More)
We introduce the national research biobanking infrastructure, BBMRI_CZ. The infrastructure has been founded by the Ministry of Education and became a partner of the European biobanking infrastructure BBMRI.eu. It is designed as a network of individual biobanks where each biobank stores samples obtained from associated healthcare providers. The biobanks(More)
Vitamin D is the third steroid hormone playing important bio-logical roles in the development of breast cancer. Decreased plasma levels of its 25- hydroxyderivative, 25OHD, display robust associations with higher incidence of breast cancer and shorter overall survival. Although no consensus exists, most authors agree that optimal plasma levels shall be(More)
BACKGROUNDS Recently, research at genetic and molecular levels has extensively accelerated due to advances in new technologies. Since the mid-90s, a relatively new discipline--clinical proteomics, has evolved, which focuses on studying gene products--proteins. The evaluation of protein profiles may contribute to the more accurate stratification of patients(More)
