With aging, our brains become more susceptible to disease and injury. Different regions of the brain have differing levels of vulnerability to stress and injury, and this brain region-dependent variability to vulnerability could be partly explained by the existence of glycosphingolipids within the cell’s plasma membrane called gangliosides. Gangliosides are expressed predominantly within the brain and play various roles within the central nervous system including neural repair, cell survival, and neurodegeneration. Our laboratory has demonstrated that gangliosides can shift their composition from GM1 back to GM2 and GM3 following stroke in mice and rats indicating a role for simple gangliosides …

Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders affecting reproductively aged women. Women with PCOS and ewes prenatally exposed to testosterone (T) show similar reproductive and metabolic defects, including anovulatory dysfunctions stemming from abnormal gonadotropin releasing hormone (GnRH) secretion and insulin resistance. For this dissertation, I examined the effects of prenatal T treatment on androgen receptor (AR) and insulin receptor (IR) expression with the reproductive and metabolic neurons of the hypothalamus, the ARC KNDy (co-expressing kisspeptin, neurokinin B/dynorphin), AgRP (agouti-related peptide) and proopiomelanocortin (POMC) neurons, and the preoptic area (POA) kisspeptin neurons, and the GnRH neurons. …
