观察活细胞的有丝分裂过程

Early microscopic images of cells and subcellular organelles were obtained using fixed cells. In this lecture, Dr. Inoue recalls how, in 1947, he built a polarizing light microscope that allowed him to visualize, for the first time, the dynamic mitotic spindle in live cells.

细胞质处理小(P-小)和mRNA的周期

Roy Parker (U. Colorado Boulder/HHMI) Part 2: P-bodies and the mRNA Cycle

In the second part of this lecture, I will provide an overview of why the regulation of translation and mRNA degradation is an important aspect of the control of gene expression in eukaryotic cells. In addition to the translating pool of mRNAs associated with polysomes, recent experiments have identified P-bodies and stress granules as specific cytoplasmic compartments wherein untranslated mRNAs accumulate. In addition to mRNAs, P-bodies tend to contain translation repressors and mRNA degradative enzymes, while stress granules reflect mRNAs in association with some translation initiation factors and RNA binding proteins. P-bodies and stress granules interact and suggest a dynamic process wherein eukaryotic mRNAs remodel their interacting proteins and enter and exit translation, thereby affecting the control of mRNAs in the cytoplasm. We are interested in defining the mechanisms by which P-bodies and stress granules assemble and how cells regulate the movement of mRNAs between these different biochemical and cell biological compartments. Several approaches will be described including biochemical and genetic analyses of known proteins modulating these events, as well as the identification of new factors affecting P-body and stress granule formation and function.

In 2012, Roy Parker joined the University of Colorado, Boulder after many years at the University of Arizona.

研究寄生虫的质,提供药物开发的新靶点

David Roos (U Penn) Part 2: The apicomplexan plastid

Antibiotics are effective because they kill bacteria without harming humans and other eukaryotes (organisms with cells that contain nuclei). So why are the eukaryotic parasites responsible for malaria and toxoplasmosis killed by drugs like clindamycin? Multidisciplinary studies integrating molecular genetics, cell biology, biochemistry, pharmacology and computational genomics reveal that such drugs target an unusual organelle. The "apicoplast" was acquired when an ancestral organism 'ate' a eukaryotic alga, and retained the algal plastid -- a relative of plant chloroplasts derived from a bacterial ancestor. Although no longer photosynthetic, the apicoplast is essential for parasite survival, providing new targets for drug development. See more at http://www.ibioseminars.org
