Taking advantage of this, researchers can insert
therapeutic genes into a virus, then use the viruses to shuttle the genes to the appropriate cells or tissues inside a human body.
Finding a safe way to get
therapeutic genes into the cells has been a major challenge, however.
The virus inserts
the therapeutic gene into the cell's DNA and uses its instructions to produce a receptor protein — a modified version of a common glutamate receptor ion channel - that they display on their surface.
Not exact matches
This fact is rooted in a packaging problem: the
gene encoding FIX is much smaller than the
gene for FVIII, and better fits
into a vector, usually a harmless virus, designed to deliver
therapeutic genes to a patient.
For
gene therapies, scientists remove most of the AAV genome, replace it with
therapeutic genetic cargo, and inject trillions of copies
into the patient.
The vector then unloads its genetic material containing the
therapeutic human
gene into the target cell.
Like mRNA,
gene therapy can induce cells to make
therapeutic proteins, but it typically introduces DNA that can integrate unpredictably
into the genome.
Crucially, only the
therapeutic gene is incorporated
into the hybrid virus, so it can not replicate.
In the study published in the journal Science Signaling, the team led by LLuís Espinosa, investigator of IMIM's research group
into stem cells and cancer, have shown that inhibition of endosomal activity is a potential
therapeutic strategy for the treatment of cancers with the BRAF mutated
gene.
Carrying the
therapeutic genes, AdV made it
into the patients» livers.
Here, the researchers delivered a
therapeutic gene along with a short hairpin RNA (shRNA)
into liver cells in mice.
Their work could overcome a stumbling block for
gene therapy by ensuring that a
gene is actually inserted
into a target cell's chromosome, where it will order the production of
therapeutic proteins.
Gene therapy offers the possibility of replacing the function of the defective or missing gene with that of a therapeutic gene inserted into the c
Gene therapy offers the possibility of replacing the function of the defective or missing
gene with that of a therapeutic gene inserted into the c
gene with that of a

Since then he has continued to investigate new strategies to overcome the major hurdles to safe and effective
gene transfer, translate then
into new
therapeutic strategies for genetic disease and cancer, and allowed new insights
into hematopoietic stem cell function, induction of immunological tolerance and tumor angiogenesis.
The discovery of new
genes involved in these repair mechanisms is very important in order to understand the development of these tumours and delve more deeply
into their
therapeutic vulnerabilities.
A DNA - covered submicroscopic bead used to deliver
genes or drugs directly
into cells to treat disease appears to have
therapeutic...
The condition is more common than muscular dystrophy and cystic fibrosis, but the development of new
therapeutic concepts is hindered by the fact that unlike muscular dystrophy and cystic fibrosis, where a single mutated
gene causing the disease is known, the entire human chromosome 21 (containing around 300
genes) still has to be dissected
into individual
gene - dose contributions to the DS symptoms.
SOX2 is one of two key
genes researchers use to generate induced pluripotent stem cells (iPSCs), which are capable of differentiating
into all cell types for research and potential
therapeutic applications.

The first step in both direct and cell - based
gene therapy is packaging a
therapeutic transgene
into a delivery vehicle (e.g., a viral vector), followed by expansion of its host cell lines to produce high - enough vector concentrations.
This overview describes how newly identified
genes implicated in human neurodegenerative diseases are making their way
into the easy - to - manipulate fruit fly and providing new insights
into disease pathology and
therapeutic avenues.
