Melanin

surprising to see how each of our gene is closely related. While watching the video, I was surprised by the skin color measurement test, I questioned about the validation of the test, for the reason that our skin tone could easily be affected by the melanin pigment, as a reaction to the ultraviolet light in the

Where Did Blue Eyes in Humans Come From? Humans are one of the few mammals who have the blue eye phenotype. A few species of primates have the blue eye phototype as well, including blue eyed black lemurs. However, humans are the most notable carrying of the blue eyed phenotype. This paper will examine the cause of blue eyes in humans and will explore research done to discover why blue eyes survived from a simple mutation along the evolutionary trail to present day. There are two layers

Did you know redheads are mutants? Yup! The gene that causes red hair is a mutation of the gene MC1R. There is an Ancient Greek superstition that redheads mutate into vampires when they die, and I guess it’s based off fact. In this paper, I will explain the different stereotypes of hair color, where they come from, and where the actual color of hair comes from scientifically. I will mostly be talking about women and girls when I talk about stereotypes, only for the reason that they are stereotyped

Melanoma is a type of skin cancer that develops in the skin’s pigment cells, also referred to as melanocytes. These melanocytes create melanin, which helps protect our skin form UV (ultraviolet) rays that come from the sun. A mole may form when these melanocyte cells cluster together, usually occurring at a young age. Sometimes, the melanocytes in the moles may start to grow and disperse in an uncontrollable way and grow outwards or downwards into the lower layers of the skin. This uncontrollable

pigment that gives a skin, hair, and eye color. When people have vitiligo the skin becomes whiter, and it usually occurs on skin on both sides of the body. The exact trigger is not known, but it relates to the immune system to attack, destroy the melanin-forming cells because of the family history, sunburn, stress, or exposure to chemicals. It can happen at any age, but usually occurs before the age 20. In the article “For Vitiligo Patient, Arthritis Drug Restores Skin Color” from June 24, 2015

for example one of the pink areas is on top of the Anders Mountains in South American. 5. In the film, Dr. Jablonski explains that melanin, located in the top layer of human skin, absorbs UV radiation, protecting cells from the damaging effects of UV. Genetics determines the type of melanin (i.e., brown/black eumelanin or red/brown pheomelanin) and the amount of melanin present in an individual’s cells. Based on this information, write a hypothesis for where in the world you would expect to find human

Vitiligo is a disease in which the melanocytes (the component of the skin that determines the amount of pigment of one’s skin) in the skin become destroyed, leaving patches of light-colored skin. There are several theories about what causes vitiligo. One claim is that it is an auto-immune disorder, meaning that the melanocytes attack themselves and become destroyed in some places. Another explanation is that it is caused by emotional distress. So far, there is not enough substantial evidence to prove

Albinism, also known as Achromasia, is a genetic disease that affects the integumentary system and the visual system. Albinism makes the body unable to distribute or produce melanin in the skin, eyes, nails, and/or hair. Albinism occurs in all racial and ethnic groups around the world. Albinism affects nearly 18,000 to 20,000 in the United States alone, and can is as high as 1 in 3,000 in other parts of the world. [1] A common misconception is that all forms of albinism affect the skin, but there

Prognosis The prognosis for all three forms of Griscelli syndrome is variable as per the type and whether or not treatment was given. As previously noted, HSCT has proven to be successful in the treatment of GS2. Patients receiving HSCT treatment have a considerably high chance (80 percent, according to the study above) of being cured of the disease and living a normal life following treatment. On the other hand, if a patient is diagnosed with GS2 and does not receive treatment, their prognosis

INTRODUCTION: Melanoma is a type of cancer that develops in the melanin cells located in the skin. Melanin can cause the pigment of the skin to appear dark when in abundance. Gray horses are especially susceptible due to the abundance of melanin in their skin cells. On the cellular level of the disease, the melanocortin 1 receptor (MC1R) gene provides instructions for making a protein called the melanocortin 1 receptor. This receptor is what allows for normal skin pigmentation and is located of
