Gene Transfer to the Uterine Endometrium
Title:In vivo gene transfer to the uterine endometrium

Synopsis:Our capacity to modulate uterine function is very basic-
hormone replacement (estrogen and progestins), oral contraceptives, anti-steroids
(Tamoxifen, clomiphene, RU 486), antiprostaglandin agents (ibuprofen, aspirin).
Our understanding of reproductive biology has outweighed our therapeutic
advances. This Cambridge group has directly transferred specific genes to
human endometrium in vitro and mouse endometrium in vivo and offers this
as a new approach to regulation of uterine function. Using marker genes,
DNA is complexed with lipids to form liposomes. These are taken into epithelial
cells avoiding the more common use of viral agents and the possibility of
viral recombination. While a "reporter" gene was used by the
researchers, the technique possibly can be extended to transfer of genes
that could enhance or retard uterine function. There still remains the problems
of the cyclic turnover of the endometrium and the availability of the desired
genes to transfer. However, this represents the first description of this
strategy and a valuable tool for the study of uterine function. It certainly
will have far reaching therapeutic implications for improving or preventing
implantation, and for medical therapy of diseases only surgically correctable
at present.
