摘要:
The present invention provides a vector system in which a MuLV-Gag gene, a MuLV-Pol gene, and a GaLV-Env gene are expressed in two separate vectors. The vector system is capable of inserting a therapeutic gene to these two separate vectors, and in this raged, the size of an inserted gene is not limited and a variety of foreign therapeutic genes may be inserted to the vectors. Accordingly, the foreign therapeutic gene may be delivered in a safe and efficient manner to desired tissue of cells of aberrant proliferation. Therefore, the vector system is applicable in a composition for delivering a gene targeting the aberrantly dividing cells of aberrant proliferation, wherein the composition includes a retrovirus produced by cell line transfection. The vector system is also applicable in a composition for preventing or treating a disease caused by cells of aberrant proliferation of, such as cancer cells.
摘要:
The present invention relates to compositions and methods for creation of vector nucleic acid sequences (e.g., retroviral nucleic acid sequences) that comprise two or more exogenous nucleic acid sequences that encode highly homologous (e.g., identical) polypeptide sequences, yet wherein at least one of the exogenous nucleic acid sequences has been mutated using degenerate codons for purpose of reducing homology between the two or more exogenous nucleic acid sequences while maintaining the encoded polypeptide sequence. Preferred nucleic acid sequences include those encoding multi-chimeric immune receptor (CIR) genes. Specific nucleic acid sequences of such CIR genes are also disclosed.

Embodiment herein provide specially designed synthetic BCL11A-targeting microRNAs for RNA polymerase II expression, and methods o use to treat hemoglobinopathies such as sickle cell disease or thalassemia by increasing the expression levels of fetal hemoglobin levels. In particular illustrative embodiment, the present invention provides, in part, improved compositions and methods for achieving gene therapy in hematopoietic cells and hematopoietic precursor cells, including erythrocytes, erythroid progenitors, and embryonic stem cells. The invention further provides improved gene therapy methods for treating hematopoietic-related disorders.
