Much of that progress has come about because of the development of the molecular gene editing tool CRISPR (which stands for Clustered Regularly Interspaced Short Palindromic Repeats) that allows biochemists to literally cut and\/or paste sections of DNA into the chromosomes of living cells. I have talked about CRISPR several times in previous articles, see posts of 2 March 2019, 12 January 2019, 1 December 2018, 1 September 2018 and 5 August 2017, and the full potential of CRISPR is still only being guessed at.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"883\" height=\"912\" src=\"http:\/\/scienceandsf.com\/wp-content\/uploads\/2019\/08\/CRISPR-1.jpg\" alt=\"\" class=\"wp-image-2321\" srcset=\"https:\/\/scienceandsf.com\/wp-content\/uploads\/2019\/08\/CRISPR-1.jpg 883w, https:\/\/scienceandsf.com\/wp-content\/uploads\/2019\/08\/CRISPR-1-290x300.jpg 290w, https:\/\/scienceandsf.com\/wp-content\/uploads\/2019\/08\/CRISPR-1-768x793.jpg 768w\" sizes=\"auto, (max-width: 709px) 85vw, (max-width: 909px) 67vw, (max-width: 1362px) 62vw, 840px\" \/><figcaption>How CRISPR Works (Credit: Cambridge University Press)<\/figcaption><\/figure>\n\n\n\n<p>Now the latest experiment is making a bold and daring attempt to treat fully grown persons who are sufferers of the inherited genetic disorder Sickle Cell Anemia, a condition that affects about 100,000 people living here in the United States and millions of others worldwide.

This is a disorder that affects the bone marrow and leads to the production of red blood cells with a defective protein that causes the cells to be deformed, sickle shaped. These deformed blood cells are thereby unable to carry a normal amount of oxygen leading to a permanent and in some cases crippling weakness in the affected person. Most sufferers of Sickle Cell Anemia are ethnic African or African-American and since the disease is inherited it can devastate a family for generations.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"630\" height=\"586\" src=\"http:\/\/scienceandsf.com\/wp-content\/uploads\/2019\/08\/SickleCellInheritance.jpg\" alt=\"\" class=\"wp-image-2323\" srcset=\"https:\/\/scienceandsf.com\/wp-content\/uploads\/2019\/08\/SickleCellInheritance.jpg 630w, https:\/\/scienceandsf.com\/wp-content\/uploads\/2019\/08\/SickleCellInheritance-300x279.jpg 300w\" sizes=\"auto, (max-width: 709px) 85vw, (max-width: 909px) 67vw, (max-width: 984px) 61vw, (max-width: 1362px) 45vw, 600px\" \/><figcaption>Sickle Cell Anemia is an inherited genetic disorder (Credit: Synthego)<\/figcaption><\/figure>\n\n\n\n<p>The procedure being tested is to take cells from the patient&#8217;s bone marrow and modify the cells DNA using CISPR in order to make them produce a protein that is normally only formed by the human body while in the womb and during early childhood. It is hoped that the production of this protein will correct the deformations of blood cells caused by the defective protein, thereby alleviating the anemia caused by sickle cell.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"700\" height=\"362\" src=\"http:\/\/scienceandsf.com\/wp-content\/uploads\/2019\/08\/SickleCellCRISPR.jpg\" alt=\"\" class=\"wp-image-2324\" srcset=\"https:\/\/scienceandsf.com\/wp-content\/uploads\/2019\/08\/SickleCellCRISPR.jpg 700w, https:\/\/scienceandsf.com\/wp-content\/uploads\/2019\/08\/SickleCellCRISPR-300x155.jpg 300w\" sizes=\"auto, (max-width: 709px) 85vw, (max-width: 909px) 67vw, (max-width: 984px) 61vw, (max-width: 1362px) 45vw, 600px\" \/><figcaption>Possible Techniques for using CRISPR to cure Sickle Cell (Credit: American Chemical Society)<\/figcaption><\/figure>\n\n\n\n<p>The experimental treatment for Sickle Cell Anemia is being conducted at eight hospitals and clinics in North America and Europe and is being overseen by CRISPR Therapeutics of Cambridge Massachusetts in association with Vertex Pharmaceuticals of Boston.
