16. Molecular mechanisms of human mitochondrial dynamics : inspiration and challenge
Abstract : Mitochondria are highly dynamic organelles in cells. They frequently change the morphology via continuous fission and fusion events, referred to as mitochondrial dynamics, which includes the shape, size and number of mitochondria in the cell, as well as mitochondrial subcellular distribution and mitochondrial quality control.

17. Oxidative damage and the DNA glycosylase MutYH
Abstract : The DNA glycosylase MutYH is highly conserved throughout evolution, and homologs are found in most eukaryotes and prokaryotes examined. MutYH functions as a base excision repair DNA glycosylase that excises adenines misincorporated opposite 8-oxo-7,8-dihydro-2′-deoxyguanosine (8-oxodG), one of the most stable products of oxidative DNA damage.

18. Chromatin remodeling and dna topology in transcription and genome stability
Abstract : Eukaryotic DNA is wrapped around histone proteins to form nucleosomes, the fundamental repeating unit of chromatin. DNA packaging into chromatin both solves and creates problems. It allows the centimeters, or even meters, of DNA that constitute a eukaryotic genome to fit inside a micrometer-scale cell nucleus. READ MORE

19. Interplay of chromatin remodeling, transcriptional regulation, and nuclear organization
Abstract : Transcription is regulated on different levels to ensure that genes are expressed at the correct time and in the amounts required. At the chromatin level, DNA is wound onto histone proteins, forming nucleosomes that influence accessibility of DNA elements. READ MORE

20. Studies of histone modification systems in Schizosaccharomyces pombe
Abstract : 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. READ MORE
