3. Researchers have been successful in genetically engineering mice by inserting a hyperactive form of a mouse gene (PGC-1B) into growing embryos. They observed that a muscle fiber called IIX became more abundant in PGC-1B hyperactive mice. They also observed that PGC-1B hyperactive mice were capable of running for longer stretches of time (average 33 minutes) than control mice that were not altered (26 minutes). 3a. Based on your knowledge of muscle fiber composition (i.e. slow-twitch, fast-twitch), propose an explanation...

For some diseases, you might not have to infect the cell responsible for the disease. For example, the inability to produce insulin causes diabetes. If you could get the cold virus to convince your lung cells to secrete insulin, you might be able to treat diabetes without having to infect pancreatic cells (the site of normal cell insulin production). Would muscular dystrophy or obesity be treated via this indirect approach? Why?

While at the dermatologist’s office you notice a brochure for a product that promises to erase “crow’s feet” and “frown lines.” You are curious about what this product is and how it works. As you read the brochure you notice it is called Botox and is injected into the facial muscles. BOTOX® Cosmetic, or onabotulinumtoxin A, is only available by prescription. You know that this cosmetic is botulinum toxin, and you remember from your human anatomy & physiology course that...

State rational for your answer: 6) In unstimulated muscle cells, the glucose transporter Glut4 is present in the membrane of endosomes. Upon stimulation of these cells with insulin, the endosomes fuse with the plasma membrane, thereby depositing Glut4 in the plasma membrane, where it serves to transport glucose into the cells. In order for insulin to elicit this change in Glut4 localization, insulin...

1. You are studying an integral plasma membrane protein named LINKER that can interact with the cytoskeletal molecule spectrin to form complex matrices across the surface of membranes. To begin to understand how the LINKER protein population responds to spectrin availability, you perform some fluorescence recovery after photobleaching (FRAP) experiments using a LINKER-GFP fusion protein. The results of a FRAP experiment with the wildtype version of LINKER in which 50% of the protein population is bound to spectrin is shown...
