can be taken to detect breast cancer early in its stages. Women who believe they have a higher risk should have the breast cancer gene testing. In order for a woman to consider her case of breast cancer to be hereditary, she must contain either the BRCA1 or BRCA2 gene mutation in her genetic make up. Hundreds of mutations have been found in both genes and almost all of the mutations identified are primitive mutations found in only a single family. Most of the mutations result in a miss-formed protein
C-terminal of a gene called BRCA1 (or “Breast Cancer 1, Early Onset Gene”) tumor suppressor. The BRCA1 gene is located on the long (q) arm of chromosome 17 at region 2 band 1, consists of 24 exons and encodes a multidomain protein of 1863 amino acid residues in human2. The BRCA1 proteins produced from BRCA1 gene help preventing cells from growing and dividing too rapidly or in an uncontrolled way3. The family of BRCA1 genes is called RING-type zinc fingers or RNF. The BRCA1 protein is characterized
The two genes most commonly associated with ovarian cancer are BRCA1 and BRCA2; BRCA1 and BRCA2 are human genes that produce tumor suppressor proteins. The proteins help repair damaged DNA, but when either of these genes are mutated, DNA may not be repaired properly. As a result, cells would be more likely to develop additional

highest percentage of death. It also had the highest number of preventative oophorectomies. BRC2 had half the number of patients and less than a third of the death rate of BRCA1, With the patient number and the number of deaths, a woman has approximately a 1 in 5.5 patients chance of dying from breast cancer if she has the BRCA1
family i.e., it is hereditary and hence can be inherited from our family. Breast cancer can also develop in males, but is very rare. About 1% breast cancer develop in males. The two main genes that are mainly responsible for this catastrophe are “BRCA1 (Breast cancer 1)” and “BRCA2 (Breast cancer 2)”. These genes produce “tumor suppressor” proteins whose normal function is to inhibit cell division and repair the damaged DNA, hence keeping the cell’s genetic material healthy and stable. Hence it can
For example, if someone is of Jewish descent have a higher prevalence of harmful BRCA1 and BRCA2 mutations than people in the general population. Other ethnic and geographic populations around the world, such as the Norwegian, Dutch, and Icelandic peoples, also have higher prevalences of specific harmful BRCA1 and BRCA2 mutations. In addition, limited data indicate that the prevalence of specific harmful BRCA1 and BRCA2 mutations may vary among individual racial and ethnic groups in the United
For the Health Assessment and Health Promotion portion of NURS 255, we were paired with 66 year old G.T., a resident of the senior living community Freedom Village. Over the course of two visits, we were able conduct a health history and physical assessment on our client, who was in outstanding health in comparison to her other individuals her age. She even reported, “this may not be too interesting to you -- I don’t have much wrong with me.” Our health assessment was incredibly average, with normal
predictive genetic screening is only available for a handful of diseases, its effects and ramifications have become hotly debated issues in a wide range of areas, from government to religion. The debate began in the 1993 when researchers isolated the BRCA1 gene, which is associated with increased risk of developing breast and ovarian cancer. The discovery of this gene led to excitement and speculation of developing a predictive genetic test to identify those women at risk for these cancers. In this paper
the spread of diseases and other genetic defects and predispositions to the next generation. For example, the mutated gene responsible for breast cancer, BRCA1, is most often passed down maternally. If a person inherits two copies of the mutated BRCA1 gene, then he or she has a very high chance of developing breast cancer (Regalado). If the BRCA1 gene is corrected, and the mutation is fixed using CRISPR, breast cancer could essentially be avoided. Although it will not be completely eradicated, the

I know that cancer is a deadly disease and you would want to do all you can to prevent it from happening, especially to your two daughters. There is a variety of genetic testing that you can use to your advantage to check for breast cancer, which I would not blame you for using. However, before you go off and have your daughters tested for cancer, please note that these tests may be unnecessary and there is a possibility that you are wasting money. I will tell you about what I have learned from biology

For several decades, patents have been issued for the genes of various life forms including plants, animals, and segments of human DNA. Typically, gene patent holders are researchers in federal organizations, colleges, and companies; they often collect patents as a means for protecting their investment in research. The U.S. Patent and Trademark Office allows for genes to be protected as intellectual property with the intention of encouraging research and innovation, just as with any patent. However
I decided to study this in more depth, reading articles where I found that BRCA1 and BRCA2 genes have been found to be linked to breast cancer and one of the reasons women get it far more than men is due to their lifetime oestrogen exposure. I undertook two work placements; two weeks at the Laurel Lodge Clinic, Hillingdon and one
As many of you know October is National Breast Cancer Awareness month. Breast cancer is a disease that not only affects women in general, but it will have an impact on many of us in some way. It is important for us to get informed of the many disease that can invade our body systems and how we can prevent such disease to interfere with our health. In that in mind, I will be sharing with you what is breast cancer, the stages, and how we can change our lifestyle to prevent this disease. Many assume
CREB-1 (Ca2+/cAMP response element binding protein-1) Ca2+/cAMP response element binding (CREB-1) protein is a transcription factor that regulates cell growth, homeostasis and survival. A TM phosphorylates CREB at Ser111 in response to IR. This, in turn, triggers CK-2 dependent phosphorylation of Ser108 and CK1 dependent phosphorylatio~ ofSer114 and Ser117. The phosphorylation of Ser 114 and Ser 117 by CK1 renders CREB permissive for ATM dependent phosphorylation at Ser121 (Shanware et al., 2007)
Breast Cancer Among Women Breast cancer is a type of cancer that starts in the tissue of the breast and spread to the surrounding area of the breast. This cancer most normally begins from the inner lobules of the breast, which are called the ducts and is better known as the part of the breast that makes milk. After a woman develops cancer, she is tested to determine what type of cancer she has and which treatment is best for her. Some treatments for cancer are surgery, hormonal therapy, immunotherapy
being in order to pinpoint mutations that may lead to disease. This type of screening is performed before the person has developed symptoms (presymptomatic testing). Some notable genes/proteins/mutations that can found during predictive testing are: BRCA1, BRCA2, HLA-B27, and CAG trinucleotide repeat in HTT. Predictive testing may have ethical ramifications as well, which include being denied health insurance based on pre-existing risk factors and discrimination from future employers and society.
