Systems approaches to understanding GnRH signalling

Perrett Rebecca , Voliotis Margaritis , Armstrong Stephen , Pope George , Tsaneva-Atanasova Krasimira , McArdle Craig

GnRH acts via Gq/11-coupled GPCRs on gonadotropes to control synthesis and secretion of LH and FSH. We use mathematical and statistical approaches as well as automated cell imaging to explore this system. In cells expressing ERK2–GFP and GnRH receptors, GnRH pulses cause rapid and transient nuclear translocation of ERK2–GFP, providing a live-cell readout for ERK activation1. A mathematical model trained against this data predicted greater sensitivity to re...

GnRH and inflammatory signalling in the ageing hypothalamus

Cai Dongsheng

In this talk, I will discuss the integrated role of hypothalamic inflammation and GnRH dysfunction in the development of systemic aging. First, I will provide an overview on aging-related profiles of hypothalamic pro-inflammatory NF-kB pathway as well as GnRH change. Second, I will describe how these changes can employ a neurodegenerative mechanism, in particular through targeting hypothalamic neural stem cells, to mediate the pathogenesis of aging and many aging-related disor...
