Nicolaus Copernicus in the 16th century, the Sun was believed to be the center of the universe.
SCA is a common monogenic blood disorder with potentially devastating consequences due to chronic and episodic disease; it has a massive impact on the health-care system and is linked to a significant reduction in life span.
We show that gene therapy with a lentivirus vector expressing γ-globin has the potential for a one-time cure and define the parameters required to cure the disease. We also show a preclinical in vivo method for determining the minimal amount of genetically corrected hematopoietic stem cells needed to correct disease, which is important in the design of clinical gene therapy trials.
The expression of the γ-globin gene in hematopoietic stem cells (HSCs) results in enough postnatal fetal hemoglobin (HbF) to correct sickle cell anemia (SCA) in the Berkeley "humanized" sickle mouse. We assessed critical parameters for correction after de-escalating the number of transduced HSCs in transplant recipients using reduced-intensity conditioning and varying gene transfer efficiency and vector copy number.
The minimal amount of HbF, F cells, HbF/F-cell, and gene-modified HSCs required for correcting the sickle phenotype was determined using a systematic quantification of functional and hematologic red blood cell (RBC) indices, organ pathology, and life span.

Every cell in our body has chromosomes.If it has xx combination of chromosomes then it has female characteristics and if it has xy chromosomes then it has male characteristics.....
HOPE IT HELPS YOU '_'
We can start by not releasing animals in the wild and by reporting sitings of these invasive species
The correct answer is Solid.
