Material Safety Data Sheets or Safety Data Sheets (MSDS/SDS) – The Worker’s Right to Know Law grants employees the right to know the hazards of all chemicals in their work place. These hazards can be found in the MSDS or SDS forms that employers are required to maintain for all hazardous chemicals used at the facility. MSDS and SDS are very similar, but the latter is an updated version designed to increase consistency.

MSDS/SDS: (10pts) (need word file) and post the sources where to find that information

1. The extracellular matrix (ECM) was regarded decades ago as an uninteresting set of proteins and unusual carbohydrates that were required for cell adhesion and tissue integrity. Now, however, there is much more of an interest in the ECM given its importance in cancer and metastasis - a concept that is embodied in the phrase, "tumor microenvironment".

a. What is the importance of E-cadherin?

b. Collagen synthesis is unique given its final assembly stage. Explain this statement.

c. Challenge: You are working with a neuronal cell line isolated from a human brain tumor. It appears to have a neuronal phenotype when grown in culture on laminin coated dishes but appears to have more of a typical round, small (3 to 5mm) phenotype when grown on a standard, collagen-only coated dish or a poly-lysine coated (positive charge only - no ECM component) dish. Under all 3 cases the cells attach to the substrate. You suspect that the reason the neuronal phenotype is supported by the laminin coating is due to the ability of laminin, but not collagen or poly-lysine, to bind to the integrin receptors RGD binding domain thus triggering a molecular cascade that leads to the expression of the neuronal phenotype. How might you test this hypothesis?

d. Why are glycosaminoglycans important to cell differentiation, tissue generation and embryogenesis?

Discussion :

The "Online Mendelian Inheritance in Man" website (www.omim.org) is a great source for information about human genes and genetic traits. Each entry has a unique six-digit number. Autosomal dominant traits have entries that start with a 1, autosomal recessive traits a 2, X-linked a 3, mitochondrial a 5, and specific genes have a number that starts with a 6. I would like you to research one genetic disorder and write a brief paragraph describing the disorder as well as the gene involved and the function of the gene product (if known). To make this first topic easy, I am including a list of choices with a link to the Genetics Home Reference page which describes the gene and the function of the gene product and the entry number to search for on www.omim.org. If you choose a topic from my list then you do not need to post the reference. However, if you would prefer to choose a disorder that is not on the list then you will need to list your reputable source (.org/.gov/.edu).

Here is the list: please write about number 11. Holoprosencephaly, link http://ghr.nlm.nih.gov/gene/SHH
