  1. 6. Actin and myosin in transcription and chromatin regulation

    Författare :Bader Almuzzaini; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : In mammalian cells, actin and myosin have emerged as regulators of nuclear structure and function, involved in chromatin remodeling and histone modifications, and in different phases of gene transcription. Actin and myosin have also been shown to be incorporated into nascent ribonucleoprotein complexes. LÄS MER

  3. 7. Transcriptional regulation of ribosome biogenesis in skeletal muscle growth

    Författare :Chang Liu; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Resistance exercise induces skeletal muscle hypertrophy via repeated exercise bouts. The increased muscle protein synthesis together with altered muscle protein degradation contribute to the adaptation of muscle mass. The number of ribosomes dictates the protein synthetic capacity of muscle. LÄS MER

    Sammanfattning : Large-scale patterns of genetic variation in chloroplast (cp) and nuclear DNA in the widespread European herb species Silene latifolia and S. dioica were investigated using cpPCR-RFLPs, non-coding cpDNA sequences, AFLPs and sequences of the internal transcribed spacers (ITS) of nuclear ribosomal DNA (rDNA).

  5. 9. Development of molecular techniques for fungal diagnostic research

    Författare :Qing-Yin Zeng; Åsa Rasmuson-Lestander; Xiao-Ru Wang; Aino Nevalainen; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; Fungi; DNA markers; Aerosols; Detection and quantification; Environmental monitoring; Molekylärbiologi; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : Fungi are present everywhere in indoor and outdoor environments. Many fungi are toxigenic or pathogenic that may cause various public health concerns. Rapid detection, quantification and characterization of fungi in living and working environments are essential for exposure risk assessment to safe guard public health. LÄS MER

  7. 10. Studies of histone modification systems in Schizosaccharomyces pombe

    Författare :Carolina Bonilla; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The genetic information in every cell is carried in the DNA. In eukaryotes the DNA is wrapped twice around proteins called histones forming a repeating unit called the nucleosome, in fibers known as chromatin. Nucleosomes are folded into higher order structures forming the chromosomes. LÄS MER
