Chapter 9 Blog: Cell Communication (Pavan)

Page history last edited by Pavan Mahankali 13 years, 6 months ago

In the first section of this page, you will write a daily summary of that day's class.  For example in  your chapter 2 blog, your first entry should be titled 9/3/10.  You should then write a one or two paragraph summary of that day's lecture, outlining the major points.  In the second section, you are required to add two items (link to a website, video, animation, student-created slide show, student-created PowerPoint presentation) and one journal article pertaining to a topic in this chapter.  A one-paragraph summary must accompany each item describing the main idea and how it applies to the lecture topic.  Please see the PBWorks help guide for assistance embedding video and other items directly in the page.  I will also produce a how-to video on using tables to wrap text around items and other useful tips.  Please see the syllabus for organization and grading details.

Fight or Flight Response

A detailed look into the "Fight or Flight" response, a specific cell signalling event triggered by stress. It also delves into how ACTH acts as a signalling molecule through G-protein receptors, detailing the process clearly. The link provides both a video and a pdf explaining the response's individual mechanism through dated events.

 

Apoptosis Signaling Pathways

This page shows graphics of the many pathways of apoptosis, or programmed cellular death, where the cell destroys itself in response to stress, and the proteins involved. A majority of these pathways target the mitochondria or the DNA itself.

 

Analysis of the adenomatous polyposis coli (APC) gene in childhood and adolescent germ cell tumors.

The article details the analysis of the APC gene and its effects on the formation of germ cell tumors in children. Germ cell tumors were analyzed to check for a relation to aberrations in the APC gene, which enables the activation of WNT signal receptor regulators. They concluded that APC abnormalities were responsible for the activation of the WNT signalling pathway, but is probably not the sole cause of childhood germ cell tumors.
