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. ...
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...
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. ...
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 ...
Joint destruction in rheumatoid arthritis : experimental, clinical and epidemiological studies
(2007-11-23)
Background: Rheumatoid arthritis (RA) is a common autoimmune disease
characterized by chronic polyarticular synovial inflammation. Erosive
joint destruction represents a major unsolved complication of RA.
Objectives: ...
Swedish moist snuff and the risk of cardiovascular diseases
(2007-10-19)
The snuff consumption in Sweden has increased substantially during recent
decades and today more than every fifth male adult uses snuff daily.
However, the evidence on health effects from long-term use of snuff is
limited, ...
Molecular mechanisms of estrogen action in relation to metabolic disease
(2007-11-16)
Estrogens have multiple effects on the body. Most studied are the
effects on female reproduction. In this thesis, we have focused on the
metabolic effects of estrogens. Estrogen treatment decreases adipose
tissue mass ...
Regulation of insulin-like growth factor-1 receptor expression and signaling
(2007-05-25)
Insulin-like growth factor-1 receptor (IGF-1R), a member of the insulin
receptor tyrosine kinase family is a broadly expressed transmembrane
receptor that plays a key role in malignant cell growth. IGF-1R transmits
information provided...
Alcohol and inflammation : a study of effects of ethanol on endothelial and epithelial cell functions
(2007-10-26)
to become ex-posed to ethanol following ingestion. In this thesis I explored their reactions to ethanol and EtP in the setting of an acute inflammatory reaction, e.g. after challenge with LPS, IL-1, TNFalpha or LTB4 mimicking, for instance, sepsis...
Charcterization of biotransformation systems in human cells
(2007-05-25)
and xenobiotic-induced hepatotoxicity, the expression of biotransformation enzymes was evaluated. The protein expression of glutathione transferases (GSTs) in hepatocyte-like cells was studied and results show high levels of GSTA1-1, whereas GSTP1-1...
