BackgroundTurf: composed of crumb rubber to cushion the
landing when a runner’s foot hits the turf

Background Amy Griffin has found 63 former soccer players
with cancer who played on artificial turf (2015)Majority are goal keepers: spend most time on
groundPlayers were exposed regularly for long periods
of time

PurposeDetermine whether future research is necessary
on the safety of artificial turf See if there is abnormal regulation in the MAPK1
gene homolog after yeast is exposed to the synthetic turf field from Pine Crest School.

Methods Since human and vertebrate animals were not an option, I chose yeast
as my medium. Curious if a chemical was leeched out of the turf after exposure to
realistic field conditions Approximately 8 hours of sunlight a day, so exposed water with turf in it
to sunlight for 8 hours Field known to get to 140 degrees F, so heated water with turf in it at
that temperature for an hour YPD media will be created with the water that was soaked in turf pellets Cell growth in the YPD media for 18 hours RNA extraction and cDNA synthesis PCR

Discussion of first trialMAPK1 homolog is downregulated only in sun
and heat 1, sun and heat 2, and slightly in heat 2
Normal function: inhibit invasive growth, involved in signal transduction pathways, regulating filamentous growth, and phosphorylating TEC1p, a gene that helps inhibit invasive growth
When downregulated, invasive growth could occur.

Second trialPurpose: determine if age of turf makes a difference Used turf from a field (Sand Pine) that was 5 years
old this time in addition to the 1 year old turf from my school
Saw only combination of sun and heat caused the turf to downregulate
Planning on testing more genes this time alsoSame procedure but heat and sun was used for all
experimental groups

Hypothesis on future research:
TEP1 – homolog of human tumor suppressor gene, checks growth of cells, shown to be down regulated in cancers
CDK2- regulates the S phase of mitosis, shown to be up regulated in breast cancer
MAPK1- discussed previously
