Abstract
Diabetes is a chronic metabolic disease affecting an increasing number of people. Although diabetes has negative health outcomes for diagnosed individuals, a population at particular risk are pregnant women, as diabetes impacts not only a pregnant woman's health but that of her child. In this review, we cover the current knowledge and unanswered questions on diabetes affecting an expectant mother, focusing on maternal and fetal outcomes.

Abstract
Polycystic ovary syndrome (PCOS) is characterized by an oligo-anovulation, hyperandrogenism and polycystic ovarian morphology combined with major metabolic disturbances. However, despite the high prevalence and the human and economic consequences of this syndrome, its etiology remains unknown. In this study, we show that female Goto-Kakizaki (GK) rats, a type 2 diabetes mellitus model, encapsulate naturally all the reproductive and metabolic hallmarks of lean women with PCOS at puberty and in adulthood. The analysis of their gestation and of their fetuses demonstrates that this PCOS-like phenotype is developmentally programmed. GK rats also develop features of ovarian hyperstimulation syndrome. Lastly, a comparison between GK rats and a cohort of women with PCOS reveals a similar reproductive signature. Thus, this spontaneous rodent model of PCOS represents an original tool for the identification of the mechanisms involved in its pathogenesis and for the development of novel strategies for its treatment.

Abstract
Kisspeptin (KP) plays a major role in the regulation of reproduction governed by the hypothalamic-pituitary-gonadal (HPG) axis. However, recent findings suggest that the KP system is present not only centrally (at the level of the hypothalamus), but also in the peripheral organs crucial for the control of metabolism. The KP system is sexually differentiated in the hypothalamus, and it is of particular interest to study whether sex-specific responses to type 2 diabetes (DM2) exist centrally and peripherally. As collection of data is limited in humans, animal models of DM2 are useful to understand crosstalk between metabolism and reproduction. Sex-specific variations in the KP system reported in animals suggest a need for the development of gender specific therapeutic strategies to treat DM2.

High-fat diet and type 2 diabetes induced disruption of the oestrous cycle and alteration of hormonal profiles, but did not affect subpopulations of KNDy neurones in female rats. J Neuroendocrinol 2018; 30:e12651. [PMID: 30311288 DOI: 10.1111/jne.12651] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/28/2018] [Revised: 10/01/2018] [Accepted: 10/08/2018] [Indexed: 11/30/2022]
Abstract
Apart from the primary metabolic symptoms of obesity and/or diabetes, there are numerous secondary problems, including disruptions of the reproductive system. The KNDy neurones, which express kisspeptin, neurokinin B and dynorphin A and are located in the arcuate nucleus of the hypothalamus (ARC), are important regulators of reproduction. Their functions are highly influenced by metabolic and hormonal status. We have previously shown that, in male rats with experimentally-induced diabetes type 2 (but not with high-fat diet-induced obesity), there are alterations in the number of these cells. In the present study, we hypothesised that a high-fat diet (HFD) and/or diabetes type 2 (DM2) in female rats affect the oestrous cycle, hormonal profiles and the number of kisspeptin-immunoreactive, neurokinin B-immunoreactive and/or dynorphin A-immunoreactive neurones in the ARC. Rats were assigned to one of three groups: a control group fed a regular chow diet, a high-fat diet group (HFD) and a diabetic group (DM2), with both of the latter two groups receiving a high calorie diet (50% of energy from lard). The third group was additionally treated with streptozotocin to induce DM2. Their oestrous cycles was monitored and their metabolic and hormonal status were assessed. We found that HFD and DM2 female rats, despite having significant alterations in their metabolic and hormonal profiles, as well as disruptions of the oestrous cycle, showed no changes in the number of the kisspeptin-immunoreactive, neurokinin B-immunoreactive and/or dynorphin A-immunoreactive neurones in the ARC. However, slight differences in the rostrocaudal distribution of these neurones among groups were reported. In conclusion, the data from the present study, together with our previously published results in males, indicate sex differences in the response of KNDy neurones to DM2 but not to HFD conditions.
