Cell Biology Graduate Program

Introduction:

 Many of the photos  taken from texts used by our students. These are used as supplemental handouts and guides for the discussions in our lectures.  Most of these topics focus on structure/function correlations. They are not intended to be comprehensive. Some topics, like those focusing on mitochondria, will correlate with biochemistry and physiology lectures that expand students' understanding of that organelle system. 

Cell Biology topics:

• transport and sorting
  • routes through the Golgi complex
  • production of lysosomes
  • gatekeepers for cell compartments:
    • rough endoplasmic reticulum
    • nucleus
    • mitochondria
    • peroxisomes
• receptor mediated endocytosis
  • internalization
  • types of ligands
  • events during process
    • patching and capping
    • role of clathrin
    • role of adaptin
  • effect of temperature
  • how many types of receptors/coated pit?
  • entry of cholesterol
• microtubule dynamics
• cell powerhouses
  • powerhouse organization
  • inner membrane substructure
  • life cycle

• translation of mRNA
• membrane architecture
  • role of phospholipids
  • role of cholesterol
  • role of glycolipids
  • insertion of proteins
  • how cell biologists study:
    • membrane cytochemistry
    • membrane fluidity
    • transmembrane structure: freeze-fracture
  • junctional specializations
  • microvilli
  • adhesion_molecules
  • membranes: lecture slides
    
    
• Cilia structure and dynamics
• Cytoskeletal microfilament structure
• Nuclear organization
• organization of chromosomes
• nucleolar structure and function
• movement through nuclear pores
• Epithelial polarity
• Adhesion_molecules

We hope that this information is useful as you study these concepts throughout your basic science and systems courses. We will keep the pages updated and appreciate any comments or questions you might have.
