An examination of transcriptional and translational regulation of the 70kDa heat shock proteins following amputation of the tail and forelimb in the newt Notophthalmus viridescens

Several stresses to tissues including hyperthermia, ischemia, mechanical trauma and heavy metals have been demonstrated to affect the regulation of a subset of the family of heat shock proteins of70kOa (hsp70). In several organisms following some of these traumas, the levels of hsp70 mRNA and proteins are dramatically upregulated. However, the effects of the stress on limb and tail amputation in the newt Notophthalmus viridescens, involving mechanical tissue damage, have not adequately been examined. In the present study, three techniques were utilized to quantitate the levels of hsp70 mRNA and protein in the tissues of the forelimbs and tails of newts during the early post-traumatic events following surgical resection of these:: appendages. These included quantitative Western blotting of proteins separated by both one and twodimensional SDS-polyacrylamide gel electrophoresis and quantitative Northern blot analysis of total RNA. In tissues of both the limb and tail one hour after amputation, there were no significant differences in the levels of hsp70 protein measured by one-dimensional SOSPAGE followed by Western blotting, when compared to the levels measured in the unamputated limb. A 30 minute heat shock at 35°C failed to elicit an increase in the levels of hsp70 protein in these tissues. Further analysis using the more sensitive 20 PAGE separation of stump tissue proteins revealed that at least some of the five hsp70 isoforms of the newt may be differentially regulated in limbs and tails in response to trauma. It appears also that amputation of the tail and limb tissues leads to slight 3 elevation in the levels of HSP70 mRNA when compared to those of their respective unstressed tissues.

Copy of page 141 of Confederation by Joseph Pope annotated by John A. Macdonald, 1867

Joseph Pope was born in Charlottetown, Prince Edward Island in 1854. He was the private secretary to Sir John A. Macdonald from 1882-1891. He worked as the assistant clerk to the Privy Council and undersecretary of state for Canada from 1896-1909. He was appointed a Companion of the Order of St. Michael and St. George in 1901. He was later knighted as a Knight Commander of the same order. Joseph Pope was the first permanent head of the Department of External Affairs (now Foreign Affairs and Internal Trade) 1909-1925. He was an advisor to Prime Ministers from Macdonald to King. He died in Ottawa, in 1926. As well as Confederation, Pope also penned: Memoirs of Sir John A. Macdonald : A Chronicle of the First Prime Minister of the Dominion; The Day of Sir John Macdonald; Jacques Cartier, his life and voyages; Traditions and Sir John A. MacDonald vindicated : a review of the Right Honourable Sir Richard Cartwright's reminiscences as well as other books Pope’s son, Maurice Arthur Pope wrote a book about Joseph entitled Public Servant: the Memoirs of Sir Joseph Pope”.
