Etiology of DNA mutations?

Etiology of DNA mutations?

Replication error: Most changes in dna come from errors in the duplication of the dna. But changes can occur in the structure from radiation and some chemicals especially those used in chemotherapy. Most mutations are harmless, some are tracked down by your normal reparative mechanism but a few can cause trouble including cancer. ...Read more

Describe microrna gene expression deregulation in human breast cancer?

Describe microrna gene expression deregulation in human breast cancer?

Can't do in 400: The study of micro-rnas is cutting-edge and extremely arcane and you need to go directly to pubmed or one of the other big ways to access the scientific data. If someone is offering a breast cancer treatment to re-regulate your micro-rna's, call your district attorney. Glad you have an inquiring mind and i wish you luck with your project. ...Read more

What type of personality traits are associated with ABO blood groups?

What type of personality traits are associated with ABO blood groups?

There are none: Blood groups have no relationship to personality, any more than one's zodiac sign actually does. During the 1990's, a single crook wrote a series of books claiming that blood group impacted general health, personality, best diet and so forth. It was totally made up. I'm sorry this came up. ...Read more

What type of genetic mutation causes breast cancer?

What type of genetic mutation causes breast cancer?

Many: If you inherit mutated brca1 or brca2 from a parent, your odds are greatly increased. All cancers arise from accumulated mutations and natural selection over your own lifetime, but these can actually be passed from parent to child. ...Read more

Gene expression profiling predicts clinical outcome of breast cancer?

Gene expression profiling predicts clinical outcome of breast cancer?

We're Getting There: In the past, we used anatomic staging alone (tumor size, lymph node involvement) to guide rx. Gene profiling allows us a completely separate measure of prognosis, and, more importantly, can predict who may or may not benefit from different chemotherapy agents. In the future, we will hopefully be able to tailor our rx to the specific cancer being treated: the elusive personalized medicine. ...Read more

What chromosomes cause the genetic disorder achondroplasia?

What chromosomes cause the genetic disorder achondroplasia?

FGFR3 gene: Achondroplasia is a mutation in the fibroblast growth factor receptor 3, which is an inhibitor that regulates bone growth. In cases of achondroplasia, the fgfr3 gene is too aggressive, negatively impacting bone growth. ...Read more

What does genetic inheritance of hemochromatosis mean?

What does genetic inheritance of hemochromatosis mean?

Inherited: Most primary hemochromatosis is passed parent-to-child, especially if each parent supplies one defective gene, though people with a single dose may be affected. If you're not familiar with basic genetics, you need to become familiar with the terminology as it's basic to life and understanding health and disease in the 21st century. ...Read more

What is the function of protein kinases in gene expression?

What is the function of protein kinases in gene expression?

Signal transduction: Signal transduction is a way for a cell to convert an extracellular signal into a response. Some protein kinases are part of signal transduction pathways. They are cellular enzymes that modify other cellular components by adding phosphate groups to them. This causes a biochemical chain of events that may result in altered levels of gene expression. ...Read more

What type of mutation causes thalassemia?

What type of mutation causes thalassemia?

Hemoglobin: formation is affected in thalassemia. Mutation in one or both of the genes responsible for the production of hemoglobin proteins (alpha and beta globin) lead to decreased production of these proteins, decreased hemoglobin formation and resulting anemia. ...Read more

What type of genetic disorder is sickle cell anemia or trait?

What type of genetic disorder is sickle cell anemia or trait?

Hemoglobinopathy: Patients with sickle cell anemia make an abnormal hemoglobin (hgb.). Normal HGB consists of paired protein chains (globin) and an iron containing part (heme). Patients with ssa inherit an abnormal beta-globin gene from each parent. Carriers have one normal beta-globin gene and one sickle beta globin gene. The carriers (trait) have no symptoms. ...Read more

Which environment factors influence the evolution of asperger's, parallel to the genetic factor?

Social interaction: Genetic issues are not really understood. Autism spectrum disorders are complex and evolve over time. We are seeing more children in whom autism symptoms resolve as they mature. Applied behavioral analysis and social interaction contribute much. ...Read more

Is this trisomy 22 caused from one of the parents havinga genetic disorder?

Is this trisomy 22 caused from one of the parents havinga genetic disorder?

22 or 21 whatever ?: Trisomy's are causes by an abnormality at conception. The egg & sperm are both expected to bring one chromosome from each of the parents 23 pairs.If an extra comes along in the egg or sperm (usually egg), the joining produces 22 pairs & one triplet or trisomy.Chromosomes carry the genes. Too many genes confuse the cell. Some lump this with gene disorders because gene docs follow the patients ...Read more
