... the suprachoroidal injection approach delivers the gene therapy payload via the potential space between the sclera and the choroid(suprachoroidal space, or SCS). This is a potentially favored injection site for gene therapy because it may reduce the likelihood of eliciting an immunologic response due to its unique location with respect to the blood-retina barrier while simultaneously permitting adequate gene expression to control the nAMD [neovascular age-related macular degeneration] disease process. Surgical access to the SCS can be facilitated by creation of a sclerotomy, followed by introduction of a catheter or cannula. Separately, and potentially of greater interest, is for suprachoroidal gene therapy to be delivered in the clinic setting by utilizing hypodermic needles or hollow microneedles.

CONT

gene therapy: The treatment of certain medical disorders, especially those caused by genetic anomalies or deficiencies, by introducing specific engineered genes into a patient’s cells.

TALENs are a chimera of transcription activator-like effectors (TALEs) and restriction enzymes, predominantly Fok1 nuclease. The TALE proteins act as programmable DNA search engines while the Fok1 are the molecular scissors cutting the DNA target site.

CONT

Transcription activator-like effector nucleases(TALENs) are restriction enzymes that bind to DNA based on its specificity and can be tailored to cut sequences of DNA. They are made by combining TAL [transcription activator-like] binding domains, which allows entry into a cell, and a DNA cleavage domain, which is helpful in gene editing. These can be tailored to bind to any targeted area in the genome to cut any desired specific location.

Subject field(s)
  • Genetics
CONT

Since alleles derived from different parental origins that are identical in nucleotide sequence may exhibit imprinting, the differences between the paternal and maternal genetic material are due to differential programming during spermatogenesis or oogenesis. The different packaging constraints of the sperm cell compared with the ovum also may be important. The regulatory mechanisms superimpose on the nucleotide sequence of a gene to determine the location, timing and degree of expression, and are termed epigenetic effects. Epigenetic modification(rather than genetic divergence of the gametes) of the DNA is likely to be the signal that marks the sperm and egg alleles as different. Imprinting is a special type of epigenetic inheritance that is passed through the gene line into somatic tissues of the progeny and is parent-specific.

OBS

epigenetic: The absence of factors in the genotype that exerts an effect upon the phenotype.

French

Domaine(s)
  • Génétique
DEF

Altération chromosomique pouvant être héritée et réversible, qui se surimpose à la séquence nucléotidique.

OBS

Le niveau supplémentaire d'information ainsi créé permettrait, par exemple, de distinguer l'origine parentale des chromosomes.

English

Subject field(s)
  • Biotechnology
DEF

Individual primary recombinant clones(hosted in phage, cosmid, YAC, or other vector) that are placed in two-dimensional arrays in microtiter dishes. Each primary clone can be identified by the identity of the plate and the clone location(row and column) on that plate. Arrayed libraries of clones can be used for many applications, including screening for a specific gene or genomic region of interest as well as for physical.

The existence of a breast cancer susceptibility gene known as BRCA1 and its approximate location on human chromosome 17 have been known for about four years, based on family studies, but only now have scientists actually isolated, or "cloned, "the gene--pinpointed its exact location and made copies of it in the laboratory. In some families, the gene is inherited in a mutated(altered) form. Women who inherit a mutated form are highly susceptible to breast and ovarian cancers.

French

Domaine(s)
  • Génétique
CONT

Deux gènes de prédisposition au cancer du sein, BRCA1 et BRCA2 ont été découverts en 1994 et 1995 et semblent être la cause dans 5% à 10% des cancers du sein. Il faut noter que des gènes de prédisposition au cancer en général peuvent être responsables de cancers familiaux mais leur rôle direct dans cette affection est faible [...]
