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

Funding Amount
$808,447.00
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.
Is Lactic Acid Concentration In Amniotic Fluid A New Predictor Of Labour Dystocia?

Funding Amount
$682,538.00
Summary
This study will establish whether higher concentrations of lactate in the amniotic fluid of labouring women can be used as a surrogate marker to improve diagnoses of presence or absence of dystocia. Labour dystocia is a serious problem experienced during childbirth, and is one of the main indications for emergency caesarean section or forceps or vacuum delivery. Although dystocia is a common clinical problem, the current lack of a precise definition leads to considerable variation in practice.
