Understanding The Regulation Of HERG Potassium Channel In The Myometrium At The Time Of Labour

Funding Amount
$597,661.00
Summary
We have shown that a potassium channel known as hERG falls precipitously at the time of term labour and that blocking this channel causes powerful uterine contractions. This grant will determine how the expression of this channel is regulated in the myometrium and whether changes in hERG channels also occur in premature labour.
Understanding The Myometrial Transition At Term And Preterm Labour To Guide Tocolysis

Summary
This grant seeks to understand how the muscle cells of the uterus transform at the time of labour. We propose that this transformation is organised by enzymes that modify the histones around key genes. We will test if a similar pathway operates in cases of preterm labour. The results will guide the development of new ways of treating premature labour that will use targeted nanoparticles to deliver siRNA directly to the muscle cells of the uterus.

Endometrial Receptivity For Embryo Implantation: Proprotein Convertase 6 And Plasma Membrane Remodeling

Funding Amount

Summary
Implantation of an embryo into the uterus is a key step in establishing pregnancy; it requires a receptive uterus (fertile soil) and a healthy embryo (seed). Implantation failure causes pregnancy loss and infertility, and is also a major limiting factor in IVF. We have established that proprotein convertase 6 (PC6) is a master regulator of uterine receptivity for implantation. We will investigate how PC6 works in a woman’s uterus, and how we can use this knowledge to improve implantation in IVF.
