Interestingly, the risk of developing post-traumatic stress disorder only increased in individuals who are carriers of specific genetic variant  called the FKBP5 gene. Psychiatrists hope that by studying this genetic variant they can improve treatment of PTSD in children.

Hyenas are devoted mothers and they have a strong social hierarchy and they typically give birth to one or two cubs at a time. Soon after birth, the Hyena cubs move into a communal den, but they still nurse and are taken care of by their mothers. Stress hormones can be raised in a situation for instance being chased by a lion or a higher-ranking hyena. Hyenas, like other vertebrates, shut down non-essential functions, like digestion or reproduction, when escaping a dangerous situation. ]]> 2022-08-31 19:21:39 UTC https://padlet.com/ajroming/gene02/wish/2278225749 https://padlet.com/ajroming/gene02/wish/2278225851 In September of 2021, a research team from Ohio State University found that highly processed foods can harm memory in aging brains. There were 3 and 24-month-old mice and three groups of diets. A normal diet, a processed diet, and a processed diet + DHA. When the younger mice had different diets, they showed no significant difference. When the older mice had the processed diet, they expressed memory loss traits and weight gain. But, with the DHA diet, they had no memory loss and highly regulated the inflammation response gene (CRP) but they still gained weight.

They conducted this project by giving a group of mice a normal diet and another group a diet high in fat. They observed the hair follicles in the mice with a high fat diet acted differently than that of those who were on a normal diet. After a few weeks of the experiment they observed hair thinning and loss in the mice with a high fat diet.]]> 2022-08-31 19:22:03 UTC https://padlet.com/ajroming/gene02/wish/2278226087 https://padlet.com/ajroming/gene02/wish/2278226145 2022-08-31 19:22:07 UTC https://padlet.com/ajroming/gene02/wish/2278226145 https://padlet.com/ajroming/gene02/wish/2278226186 Scientists have proven that an excess of light exposure during the nighttime can lead to changing the patterns in gene expression and can lead to breast cancer. In their experiment, they found that those who were exposed to more light during their sleep hours showed a significant slowed cycling of the Per2 clock gene, which is thought to be a tumor suppressor.]]> 2022-08-31 19:22:09 UTC https://padlet.com/ajroming/gene02/wish/2278226186 https://padlet.com/ajroming/gene02/wish/2278226415 Biologists at UCLA have traced individual cells during brain trauma and have discovered that some genes play a factor in severity. The research discovered that mice with low levels of cells of a gene called Ttr had worse trauma than those with. In response they injected a hormone called T4 which function the same as Ttr, thus reducing the injury. With that being said, biologists found several genes that have been impacted by brain injury, which has recently been associated with neurotic behavior in humans. In the words of Mr. Yang, "Knowing which genes in which cells are changing in a particular person can lead to the right treatment for that person."

Harmful poisons damage the DNA, this weakens the immune system making it vulnerable to cancer. Smoking then allows a cancerous tumor to begin to grow. People who smoke nowadays have more of a risk of lung cancer than people who smokes in the 1960's even if they smoke less due to the types of chemicals and poisons in the cigarettes. Smoking basically weakens your DNA allowing there to be cancerous DNA and for it to grow/reproduce.]]> 2022-08-31 19:22:35 UTC https://padlet.com/ajroming/gene02/wish/2278226577 https://padlet.com/ajroming/gene02/wish/2278226779 In a recent study, scientists sought out to find a way to regulate your body and keep gene expression to a minimum. These scientists conducted an experiment to prove this involving meditation. In this experiment, they tracked two groups of people, one doing random activities for eight hours, and one group meditation for those eight hours. The experiment immediately proved the scientist’s hypothesis, as the meditation group showed results including drastic changes  in genetic and molecular statistics. These changes led to quicker recovery from mental illness, stress, and fatigue.]]> 2022-08-31 19:22:47 UTC https://padlet.com/ajroming/gene02/wish/2278226779 https://padlet.com/ajroming/gene02/wish/2278227173 A study on Himalayan rabbits showed how temperature can have an effect on gene expression. Himalayan rabbits carry the C gene, which is responsible for the pigments in the fur, skin, and eyes. The C gene is turned off when the temperature is above 35°C, but is fully turned on between 15°C and 25°C. In the warm parts of the rabbit the gene is turned off, causing these parts of the rabbit to be white, but in the colder area of the rabbits the gene is turned on, so the fur is black.

University of Illinois professor Gene Robinson conducted a study on gene expression, which involved using microarrays to study the brains of honey bees. He knew that honey bees developed from nurses into foragers within the hive, but he theorized that a special gene called "for" (for foraging) helped the transition. This was correct, and manipulating it to express for "caused bees to forage precociously." Scientists found that bees socializing, in the form of exchanging pheromones, also increased gene expression of for, when foragers told young bees there weren't enough foragers.]]> 2022-09-02 01:56:14 UTC https://padlet.com/ajroming/gene02/wish/2280106130 https://padlet.com/ajroming/gene02/wish/2280669016    According to Science Daily differnt oils can have many differnt affects on a person. the studies show that oils high in fat have more affect. Soybean oil and coconut oil are both high in fat and have the wors eaffects on the human brain. the worst affect are  Alzheimer's disease, anxiety, and deppression.
