Gene Expression 11 HL2 by Andrew https://padlet.com/ajroming/epigenetics2 Made with good vibes en-us 2017-04-25 01:32:41 UTC 2017-04-25 01:43:35 UTC hello@padlet.com Michael https://padlet.com/ajroming/epigenetics2/wish/167993630 Himalayan rabbits have pigmentation around their ears, foot, nose, and tail in temperatures lower than 20 C because those are the areas that lose the most heat. Above 30 C they do not have pigmentation. This is a positive gene expression as it allows the rabbits to keep heat in cold areas.]]> 2017-04-25 01:34:43 UTC https://padlet.com/ajroming/epigenetics2/wish/167993630 Netha https://padlet.com/ajroming/epigenetics2/wish/167993647
Supplemental oxygen administration used by doctors in the 1940s for premature infants.
- Causes blindnes in premature infants
- Causal relationship between oxygen administration and retinopathy of prematurity (ROP)
-Too little oxygen results in a higher rate of brain damage and mortality in premature infants.]]> 2017-04-25 01:34:58 UTC https://padlet.com/ajroming/epigenetics2/wish/167993647 Aganetha https://padlet.com/ajroming/epigenetics2/wish/167993651 [Light]
The first group of caterpillars was exposed to red, green, or blue light, while the other group was kept in the dark. It was discovered that after their development into butterflies, red light resulted in brighter wing colors, while green light resulted in darker wing colors. Blue light and the dark produced pale-winged butterflies. Caterpillars kept in the dark became larger butterflies as well.]]> 2017-04-25 01:35:04 UTC https://padlet.com/ajroming/epigenetics2/wish/167993651 Richella https://padlet.com/ajroming/epigenetics2/wish/167993800 Drosophila flies
- higher temperature leads to increase in development of wings whereas when exposed to the temperature of 25 degree Celsius, the flies showed less penetrance. ]]> 2017-04-25 01:36:32 UTC https://padlet.com/ajroming/epigenetics2/wish/167993800 Cherine https://padlet.com/ajroming/epigenetics2/wish/167994019
  • Diet consumed by male mice can affect gene expression in offspring
    • Offspring of male mice that were fed with a low-protein diet and exhibited altered cytosine methylation patterns, increased expression of cholesterol genes and decrease in cholesterol esters relative to the offspring of males fed a control diet.

    Summary = Parental diet can affect cholesterol and lipid metabolism in offspring and can act as a model to study environmental reprogramming of the heritable epigenome.

Stockard created cyclopean fish embryos by placing fertilized Fundulus heteroclitus eggs in 100 ml of seawater mixed with approximately 6 g of magnesium chloride. Normally, F. heteroclitus embryos feature two eyes; however, in this experiment, half of the eggs placed in the magnesium chloride mixture gave rise to one-eyed embryos (Stockard, 1907).]]> 2017-04-25 01:41:14 UTC https://padlet.com/ajroming/epigenetics2/wish/167994177 Anisa https://padlet.com/ajroming/epigenetics2/wish/167994240 smoking causes changes in genes that control mitotic spindle formation]]> 2017-04-25 01:41:42 UTC https://padlet.com/ajroming/epigenetics2/wish/167994240
