CIN85 is a multidomain adaptor protein involved in Cbl-mediated down-regulation of epidermal growth factor (EGF) receptors. CIN85 src homology 3 domains specifically bind to a proline-arginine (PxxxPR) motif in Cbl, and this association seems to be important for EGF receptor endocytosis. Here, we report identification of novel CIN85 effectors, all(More)
PURPOSE Many biochemical processes are closely related to ion exchange, adsorption, and catalysis. Zeolites reversibly bind small molecules such as oxygen or nitric oxide; they possess size and shape selectivity, the possibility of metalloenzyme mimicry, and immunomodulatory activity. These properties make them interesting for pharmaceutical industry and(More)
Natural silicate materials, including zeolite clinoptilolite, have been shown to exhibit diverse biological activities and have been used successfully as a vaccine adjuvant and for the treatment of diarrhea. We report a novel use of finely ground clinoptilolite as a potential adjuvant in anticancer therapy. Clinoptilolite treatment of mice and dogs(More)
The aims of this study were to assess the expression of protein products of c-myc, erbB-2, p53 and nm23-H1 gene in benign and malignant breast lesions, to estimate their possible coexpression and to correlate the results of immunohistochemical analysis with various clinicopathologic parameters. The method used was the immunohistochemical detection of the(More)
This study presents the first molecular data on the basis and the origin of Huntington disease in Croatia and is the first such analysis performed among a Slavic population. We analyzed three trinucleotide polymorphisms in the HD gene: CAG, CCG and GAG Delta2642 (E2642del) triplets. Analysis of the CAG repeat size among 44 Huntington patients (39-66 CAGs)(More)
BACKGROUND AND AIMS Colon cancer tumorigenesis is a multistep process of mutation accumulation in a number of oncogenes and tumour suppressor genes. NF1 gene protein, neurofibromin, acts as a tumour suppressor by turning the active form of Ras into an inactive form. This molecular switch has an important role in the control of the cell cycle and(More)
The synthetic route for introduction of a fluoroalkyl (7-12, 14), fluoroalkenyl (15 and 16), fluorophenylalkyl (17, 19, 20, and 22), and fluorophenylalkenyl (18, 21) side chain at C-6 of the pyrimidine involved the lithiation of the pyrimidine derivatives 3 and 3a and subsequent nucleophilic addition or substitution reactions of the organolithium(More)
The novel C-5 alkynyl substituted pyrimidine (1-11) and furo[2,3-d]pyrimidine derivatives (12-22) of l-ascorbic acid were synthesized by coupling of 5-iodouracil-4',5'-didehydro-5',6'-dideoxy-l-ascorbic acid with terminal alkynes by using Sonogashira cross-coupling reaction conditions. The new compounds were evaluated for their cytostatic and antiviral(More)
We report a rare and, to our knowledge, as yet undescribed type of collision tumour - rectal leiomyosarcoma and prostate adenocarcinoma. Our study also provides the first data on molecular alterations [polymerase chain reaction/loss of heterozygosity (LOH) analysis] of the APC, NF-1, DCC, p53, nm23-H1 and BRCA-1 genes in the two components of the collision(More)
Many hypotheses have been postulated to explain the intricate nature of the metastatic process, but none of them completely accounted for the actual biological and clinical observations. Consequently, metastasis still remains an open issue with only few metastasis-inducing proteins experimentally validated so far. Recently proposed novel metastatic model,(More)
