  2. 1. Regulation of Human Papillomavirus Type 16 Late L1 mRNA Splicing

    Author : Xiaoze Li; Avdelningen för medicinsk mikrobiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; HPV-16; cervical cancer; RNA processing; alternative splicing; splicing enhancer; splicing silencer; viral persistance; SR proteins; hnRNP proteins;

    Abstract : Human papillomaviruses (HPVs) cause almost half of the human cancers that are attributable to viruses. HPV type 16 is the most carcinogenic type among the HPVs and is detected in 50% of all cervical cancers. HPV-16 infects epithelial cells and HPV-16 gene expression is tightly linked to the differentiation stage of the infected cells. READ MORE

  4. 2. Activity of tumor-antigens in polyomavirus replication

    Author : Hongyun Li; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Tumor-Antigens; DNA Replication; Cell-cycle; Phosphorylation; J-domain; Biokemi; Biochemistry; Biokemi; Medical Virology; medicinsk virologi;

    Abstract : Polyomavirus replication needs an active cell environment, and the viral DNA replication is cell cycle regulated. Tumor antigens (T-antigens) of mouse polyomavirus, especially large T-antigen, are necessary for the replication. READ MORE

  5. 3. Polycyclic aromatic compounds (PAC) in diesel fuels and exhaust emissions : aspects of sampling techniques, chemical determination, multivariate data interpretation and PAC emissions reduction

    Author : Hang Li; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The rapid growth in the number of motor vehicles has raised serious environmental health hazard problems in urban areas associated with vehicle exhaust emissions. Exhaust emissions from heavy duty diesel vehicles are very complex mixtures containing thousands of chemical components distributed between the particulate, semivolatile and gaseous phases.

  6. 4. Studies of VEGF-B and novel PDGFs in tumorigenesis and angiogenesis

    Author : Hong Li; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The family of VEGF/PDGF growth factors and their receptors are important regulators of tumorigenesis and angiogenesis. VEGFs have been shown to play important roles in development of both blood and lymphatic vessels by effect on endothelia cells. READ MORE

  7. 5. Diverse cyclic dinucleotide signals regulate Escherichia coli lifestyle transition

    Author : Fengyang Li; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Bacteria have the ability to change their lifestyle to adapt to various environmental conditions. Cyclic dinucleotides (cDNs) are ubiquitous second messengers that can regulate fundamental lifestyle switches, such as motility versus sessility and acute versus chronic virulence, in bacteria.
