Why are diseases of the blood simpler targets for treatment by gene therapy than are many other genetic diseases?
Guida verificata passo dopo passo1
Understand that blood diseases often involve a single type of cell, such as red blood cells or white blood cells, which makes targeting them more straightforward.
Recognize that blood cells are derived from hematopoietic stem cells in the bone marrow, which can be accessed and modified outside the body before being reintroduced.
Consider that blood cells can be easily sampled and monitored, allowing for effective tracking of the therapy's progress and success.
Acknowledge that the circulatory system allows for the widespread distribution of modified cells throughout the body, enhancing the effectiveness of the treatment.
Note that many blood diseases are caused by single-gene mutations, making them ideal candidates for correction through gene therapy techniques.

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.
Gene Therapy
Gene therapy is a technique that modifies or replaces faulty genes to treat or prevent diseases. It can involve delivering healthy copies of genes into a patient's cells or repairing defective genes. This approach is particularly promising for genetic disorders, as it addresses the root cause of the disease at the molecular level.

Blood Disorders
Blood disorders, such as hemophilia or sickle cell disease, often involve specific genetic mutations that affect blood cell function. These conditions are generally more accessible for gene therapy because blood cells can be easily extracted, modified, and reintroduced into the body, allowing for targeted treatment of the affected cells.

Targeted Delivery Systems
Targeted delivery systems are methods used to direct therapeutic agents specifically to the cells or tissues that need treatment. In the case of blood disorders, these systems can effectively deliver gene therapy vectors to the bloodstream, ensuring that the therapeutic genes reach the appropriate cells, which enhances the efficacy of the treatment.

Figure E.1 illustrates the results of an electrophoretic analysis of 13 CODIS STR markers on a DNA sample and identifies the alleles for each gene. Table E.2 lists the frequencies for alleles of three of the STRs shown in the figure. Use this information to calculate the frequency of the genotype for STR genes FGA, vWA, and D3S1358 given in Figure E.1.

Injection of double-stranded RNA can lead to gene silencing by degradation of RNA molecules complementary to either strand of the dsRNA. Could RNAi be used in gene therapy for a defect caused by a recessive allele? A dominant allele? If so, what might be the major obstacle to using RNAi as a therapeutic agent?

Chimeric gene-fusion products can be used for medical or industrial purposes. One idea is to produce biological therapeutics for human medical use in animals from which the products can be easily harvested—in the milk of sheep or cattle, for example. Outline how you would produce human insulin in the milk of sheep.

Additional STR allele frequency information can be added to improve the analysis in Problem 8. The frequency of D8S1179₁₂ = 0.12. The frequency of D16S539₁₈ = 0.08 and of D16S539₂₀ = 0.21. Lastly, D18S51₁₉ = 0.13 and D18S51₂₀ = 0.10. Combine the allele frequency information for these three STR genes with the information used in Problem 8 to calculate the frequency of the genotype for six of the STR genes.
