Dysmenorrhoea, painful menstrual cramps, and heavy menstrual bleeding are common debilitating symptoms in women with or without an underlying pelvic pathology. Severity has been associated with high arachidonic acid metabolism and prostaglandin (PG) biosynthesis, which increase uterine tone, high amplitude contractions and ischaemia (Carrarelli et al., 2016). The endocannabinoid anandamide (AEA) is highly expressed in the uterus and is an indirect substrate for PG production. It is thought that shifting AEA hydrolysis in favour of prostamide formation is important for decidual remodelling, embryo implantation (Almada et al., 2016; Cui et al., 2017) and could offer pain relief (Sanchez et al., 2016). However, the complex interplay of AEA-related pathways during menstruation is poorly understood. The aim of this project is to characterise PGs, prostamides and their receptors according to menstrual phase in uterine health and disease.
Assays will be performed using human tissues from consenting women undergoing routine gynaecological surgery and from mouse models in line with Local Ethics and Home Office regulations. Lipidomics will be employed to profile PGs, endocannabinoids and other bioactive lipids, immersion will be performed for tissue contraction studies and histology, ICC and molecular techniques to assess receptor and protein expression. Findings will be correlated with clinical history and patient-reported symptoms. A cell-based modelling approach will also be used to identify the pharmacological effect of prostamides and PGs on cell metabolism and growth and to assess the value of potential therapeutic compounds. This preclinical approach should provide new insights into the paracrine pathways leading to dysmenorrhoea and heavy menstrual bleeding for potential future diagnostic and therapeutic developments.
Candidates are expected to hold (or be about to obtain) a minimum upper second class honours degree (or equivalent) in a related area/subject. Candidates with previous laboratory experience are particularly encouraged to apply.
