Oxytocin

October 6, 2011 in Peptide

Friday, February 16th, 2007, Halifax, NS, 2nd graders shook hands and shared the love of learning about Oxytocin thanks to the team of Emilie Crewe (BFA NSCADU) and Amy Holland (BSc SMU) in our first MLP in the New Year, hurray!!

Expanding and contracting rubber bands, relating stories of the comfort of a hug and the times that their pets had babies, looking at pictures of kittens and puppies suckling as well as watching parts of the classic film “101 Dalmatians” , the students were immersed in thought about how oxytocin performs three key functions: 1) to cause feelings of love from touching, 2) to cause contractions for babies to be born and 3) to cause lactation of milk from the mother.  Considering that oxytocin is shaped like a lasso, formed by a string of amino acid building blocks, the students made oxytocin inspired lasso-shaped bracelets.  Different colored beads represented the different amino acids, as each student constructed their own oxytocin bracelet to illustrate the loop of six amino acids, formed by a disulfide bond (the same kind of bond found in hair and in insulin), off of which three other amino acids dangle.  All raised their oxytocin bracelets with glee loving peptide chemistry on a MLP Friday after Valentine’s day.

Finishing our first MLP presentation in 2007, (8th total!!), team oxytocin was thanked for sharing MLP love in 2nd grade in Halifax.

MSH

Wednesday, May 30th, 2007, Halifax, NS, 2nd graders blocked the sun and shouted MSH (mush), MSH, MSH … as the team of Jeff Farrell (BSc, SMU) and Valerie Walker (MFA graduate ’07, NSCADU) illuminated them about Melanocyte Stimulating Hormone, the peptide responsible for suntans and freckles.   Provided pictures about pigmentation, peptides and prevention of sunburn, the students discussed the advantages of animals that change their color, sunscreen and melanin, as they constructed a collage about MSH.  Pouring bicarbonate into cherry juice to turn it black, and returning the juice to red with the action of lemon juice, Jeff showed that just as light can change our skin color by stimulating the production of MSH in the brain, other changes in environment, such as the effects of pH, can also cause color changes.  Exposing all to some sunshine fun, Valerie enlightened us with the art of sun printing fabric paint as we made MSH-inspired bandanas.  As MSH causes skin cells to use pigments called melanin for sun protection, the students cut shapes of things that block the sun (trees, umbrellas, hats, etc.), painted landscapes with the fabric paint on cloth, applied the shapes as stencils to the cloth to block the suns effects, and awaited the photochemical changes, while sharing in the fun of cleaning up.  Looking forward to using their bandanas to block the sun this summer, all cherished exposure to some peptides and sunshine, learning about the body’s painter of pigmentation, Melanocyte Stimulating Hormone.

Insulin

MLP tastes as sweet as gingerbread cookies presenting Insulin.

Monday, the 23rd of October in Mrs Grant’s second grade class at Oxford Elementary School, thanks to Britta Fluevog (BA Sculpture, NSCAD) and Laura Foster (BSc DAL), we were guided into that tadpole-shaped yellow body behind the stomach called the “pancreas” where insulin is made.  The importance of insulin in the disease diabetes was illustrated by Laura as the students guessed the symptoms portrayed by different cartoon characters indicative of high and low blood sugar.  Using the power of cookie dough, Britta showed how nature turns a snake-shaped linear peptide into the ladder shape of Insulin.  Everyone made and tasted yummy insulin-inspired ladder cookies as we chatted about Frederick Grant Banting, the Canadian who discovered insulin and was later awarded the Nobel Prize for this discovery. With nine more peptides to go, MLP thanked team Insulin for a sweet taste of MLP creativity at Oxford.
