Strategies to increase effectiveness of growth factor receptors-targeted therapy in glioblastoma
(2007-11-14)
factor receptor tyrosine kinases
(GFR-TKs). In paper I, we showed that the pharmacologic inhibition (using
small molecule inhibitors) of IGF-1R, PDGFR and their intracellular
signalling via PI3-K and ERK1/2 kinases had only modest or not antitumour...
Studies on natural antisense RNAs and microRNAs
(2007-11-27)
Regulatory RNAs are found in all kingdoms of life and involved in
regulation of gene expression at various steps including RNA splicing,
editing, stability, modification, export, translation and chromatin
remodelling. ...
Human 15-lipoxygenase-1 and telomerase gene expression in cancer and inflammation
(2008-03-07)
Human 15-lipoxygenase type 1 (15-LOX-1) is an enzyme that catalyzes the oxygenation of free or membrane-bond polyunsaturated fatty acids containing at least one bis-allylic methylene moiety. The enzyme has been proposed to be involved in various...
Autocrine and paracrine regulation of Leydig cell survival in the postnatal testis
(2007-09-07)
by immature rats Leydig cells., (ii) possible antiapoptotic effects of IGF-I during testicular development and the role played by IGF-1R in this context; (iii) the influence of IGFBP-3 on apoptosis and steroidogenesis in rat Leydig cells in relation...
Functional genomics studies of PINK1
(2007-10-25)
established a human in vivo model for mitochondrial dysfunction. Microarray analyses of the same sample-set suggested that PINK1, a novel mitochondrial kinase, was down regulated during inactivity. PINK1 is transcribed from a complex locus, alternatively...
Identification of the susceptibility genes in type 1 diabetes and diabetic nephropathy
(2007-11-02)
Genetic susceptibility plays an important role in the pathogenesis of
type 1 diabetes (T1D) and diabetic nephropathy (DN). The present study
aims to investigate the association between single nucleotide
polymorphisms ...
Tonsillar cancer : incidence, prevalence of HPV and survival
(2008-04-04)
Since human papilloma virus (HPV) in the mid 1980ies was first observed
in squamous cell carcinoma of the head and neck, its role and impact,
especially on oral and oropharyngeal cancer, have attracted extensive
interest. ...
Aspects of immune activation in HIV-1 infection
(2007-05-25)
Abnormal immune system activation is central in HIV-1 pathogenesis leading to CD4+ T-cell depletion and inappropriate immune responses. Disease stage and HIV load strongly correlate with the immune activation level which decreases under...
Transcriptional and post-transcriptional regulation of telomerase reverse transcriptase (hTERT) expression : the role of histone modification and alternative splicing
(2008-01-18)
Telomerase, an RNA-dependent DNA polymerase responsible for telomeric DNA
elongation, is silent in most normal differentiated human cells due to
the tight repression of its catalytic unit, telomerase reverse
transcriptase ...
Statistical methodology for testing genetic association in family-based studies
(2008-04-25)
This thesis is concerned with family-based studies of association between genetic markers and binary traits. A special point of interest in family-based association studies is to separate the within family correlation and ...
