Hepatic Mitochondrial Dysfunction and Risk of Liver Disease in an Ovine Model of “PCOS Males” (2022)
Journal Article
Siemienowicz, K. J., Filis, P., Thomas, J., Fowler, P. A., Duncan, W. C., & Rae, M. T. (2022). Hepatic Mitochondrial Dysfunction and Risk of Liver Disease in an Ovine Model of “PCOS Males”. Biomedicines, 10(6), Article 1291. https://doi.org/10.3390/bi

First-degree male relatives of polycystic ovary syndrome (PCOS) sufferers can develop metabolic abnormalities evidenced by elevated circulating cholesterol and triglycerides, suggestive of a male PCOS equivalent. Similarly, male sheep overexposed to... Read More about Hepatic Mitochondrial Dysfunction and Risk of Liver Disease in an Ovine Model of “PCOS Males”.

Pubertal FGF21 deficit is central in the metabolic pathophysiology of an ovine model of polycystic ovary syndrome (2021)
Journal Article
Siemienowicz, K. J., Furmanska, K., Filis, P., Talia, C., Thomas, J., Fowler, P. A., Rae, M. T., & Colin Duncan, W. (2021). Pubertal FGF21 deficit is central in the metabolic pathophysiology of an ovine model of polycystic ovary syndrome. Molecular and Ce

Polycystic ovary syndrome (PCOS), affecting over 10% of women, is associated with insulin resistance, obesity, dyslipidaemia, fatty liver and adipose tissue dysfunction. Its pathogenesis is poorly understood and consequently treatment remains subopti...

Early pregnancy maternal progesterone administration alters pituitary and testis function and steroid profile in male fetuses (2020)
Journal Article
Siemienowicz, K. J., Wang, Y., Marečková, M., Nio-Kobayashi, J., Fowler, P. A., Rae, M. T., & Duncan, W. C. (2020). Early pregnancy maternal progesterone administration alters pituitary and testis function and steroid profile in male fetuses. Scientific

Maternal exposure to increased steroid hormones, including estrogens, androgens or glucocorticoids during pregnancy results in chronic conditions in offspring that manifest in adulthood. Little is known about effects of progesterone administration in...

Aberrant subcutaneous adipogenesis precedes adult metabolic dysfunction in an ovine model of polycystic ovary syndrome (PCOS) (2020)
Journal Article
Siemienowicz, K. J., Coukan, F., Franks, S., Rae, M. T., & Colin Duncan, W. (2021). Aberrant subcutaneous adipogenesis precedes adult metabolic dysfunction in an ovine model of polycystic ovary syndrome (PCOS). Molecular and Cellular Endocrinology, 519, A

Polycystic ovary syndrome (PCOS) affects over 10% of women. Insulin resistance, elevated free fatty acids (FFAs) and increased adiposity are key factors contributing to metabolic dysfunction in PCOS. We hypothesised that aberrant adipogenesis duri... Read More about Aberrant subcutaneous adipogenesis precedes adult metabolic dysfunction in an ovine model of polycystic ovary syndrome (PCOS).

Insights into manipulating postprandial energy expenditure to manage weight gain in polycystic ovary syndrome (PCOS) (2020)
Journal Article
Siemienowicz, K., Rae, M. T., Howells, F., Anderson, C., Nicol, L. M., Franks, S., & Duncan, W. C. (2020). Insights into manipulating postprandial energy expenditure to manage weight gain in polycystic ovary syndrome (PCOS). iScience, 23(6), Article 10116

Women with polycystic ovary syndrome (PCOS) are more likely to be obese and have difficulty in losing weight. They demonstrate an obesity-independent deficit in adaptive energy expenditure. We used a clinically-realistic preclinical model to investig... Read More about Insights into manipulating postprandial energy expenditure to manage weight gain in polycystic ovary syndrome (PCOS).

Fetal androgen exposure is a determinant of adult male metabolic health (2019)
Journal Article
Siemienowicz, K. J., Filis, P., Shaw, S., Douglas, A., Thomas, J., Mulroy, S., Howie, F., Fowler, P. A., Duncan, W. C., & Rae, M. T. (2019). Fetal androgen exposure is a determinant of adult male metabolic health. Scientific Reports, 9, Article 20195 (201

Androgen signalling is a critical driver of male development. Fetal steroid signalling can be dysregulated by a range of environmental insults and clinical conditions. We hypothesised that poor adult male health was partially attributable to aberrant... Read More about Fetal androgen exposure is a determinant of adult male metabolic health.

Developmental programming of polycystic ovary syndrome (PCOS): prenatal androgens establish pancreatic islet α/β cell ratio and subsequent insulin secretion (2016)
Journal Article
Ramaswamy, S., McNeilly, A. S., Rae, M. T., Ramaswamy, S., Grace, C., Mattei, A. A., Siemienowicz, K., Brownlee, W., MacCallum, J., McNeilly, A. S., Duncan, W. C., & Rae, M. T. (2016). Developmental programming of polycystic ovary syndrome (PCOS): prenata

Exogenous androgenic steroids applied to pregnant sheep programmes a PCOS-like phenotype in female offspring. Via ultrasound guidance we applied steroids directly to ovine fetuses at d62 and d82 of gestation, and examined fetal (day 90 gestation) and...
