Embryo cryopreservation-transfer procedure entails long-term phenotypic consequences correlated with molecular signatures in the rabbit model. Spectral Library DATA

ABSTRACT: Since the first human conceived through in vitro fertilisation in 1978, over 8 million babies have been born by assisted reproductive technologies (ART). Although most ART babies and children seem healthy, in recent years, several human and animal model studies have evidenced a potential impact of ART on long-term development. However, the long-term follow-up data in this field is still limited. Till now, studies are mainly focused on techniques such as in vitro fertilisation or in vitro culture, being the information from gametes/embryos cryopreservation field practically missing. Herein, we have developed an animal model to determine whether vitrified-thawed embryo transfer procedure has long-term consequences over the offspring. The birth weight, growth performance and adult body weight of the rabbits derived from vitrified-thawed embryos was compared with that of the naturally-conceived animals. In adulthood, the liver, heart, kidneys, spleen, lungs, gonads and adrenal glands of the males were weighed and compared. Moreover, some haematological and biochemical parameters were assessed on peripheral blood. Besides, some liver samples were obtained to perform a comparative proteomic study. The embryo vitrification-transfer process modified the birth weight and the growth pattern of the offspring, reducing the growth performance in a sex-specific manner. In adulthood, animals derived from vitrified embryos showed a significantly lower body, liver and heart weight. Molecular analyses revealed that vitrified-thawed embryo transfer procedure triggers concordant reprogramming of the liver proteome. The most relevant metabolic alteration denoted by the protein profile was that related to the oxidative phosphorylation, suggesting an impaired oxidative metabolism in the mitochondria. Furthermore, hints of dysregulation in the zinc and lipid metabolism were identified. These results evidence long-term consequences in the offspring derived from cryopreserved-transferred embryos and represented an evident example of the phenotypic plasticity exhibited by the mammalian embryo.

Nowadays, assisted reproductive technologies (ARTs) are considered valuable contributors to our past, but a future without their use is inconceivable. However, in recent years, several studies have evidenced a potential impact of ART on long-term development in mammal species. To date, the long-term follow-up data are still limited. So far, studies have mainly focused on in vitro fertilization or in vitro culture, with information from gametes/embryos cryopreservation field being practically mis ...[more]

Project description:Background: Assisted Reproductive Technologies (ART) - treatments to allow parenthood to couples facing fertility issues- have allowed the birth of > 5 million babies worldwide. Notwithstanding most of ART children are healthy at birth, several studies reported that ART may affect early-life experience causing permanent changes in fetal programming and, consequently, leading to increased predisposition to metabolic disorders in adulthood. Currently, the metabolic health status of ART children has been poorly investigated and it will take decades before large-scale population studies will be implemented. Studies on animal models indicated impaired in utero development of ART conceptuses. Relevantly, our preliminary data showed hypomethylation of liver from ART foetuses, which may contribute to the fetal programming of adult diseases. Regarding adult ART offspring, obesity, glucose intolerance and lipid accumulation in the liver have been previously described in mouse model, indicative of increased risk to develop metabolic disorders. However, little is known on the pathophysiological mechanism behind the metabolic abnormalities in ART offspring. In this context, this study investigated the influence of ART on the function of the liver, a major organ involved in the maintenance of metabolic homeostasis. Methods: To assess the influence of ART on liver functions, proteomic analysis was carried out on adult liver from 4 months old offspring developed following Embryo Transfer (ET), in vitro culture (IVC) and blastomere biopsy (BB). Control (CTR) consisted of naturally conceived offspring. Then, to verify whether and how changes in liver proteome were associated with perturbation of the metabolic status of adult offspring, general growth and physiological parameters (e.g. glucose tolerance, insulin resistance, plasmatic levels of interleukin 6, triglycerides and total cholesterol) were assessed. Results: Proteomic analysis of adult liver showed deregulated expression of proteins involved in lipid, carbohydrate and energy metabolism as well as cellular processes in adult offspring developed following BB, IVC and ET. Characterization of metabolic phenotype of adult offspring revealed increased body weight in ART offspring, glucose intolerance in BB, IVC, ET males and BB females, insulin resistance on BB offspring, low plasmatic level of Interleukin-6 in BB, IVC, ET males and high level of triglycerides and total cholesterol in BB females vs CTR which are phenotypic manifestation of liver disfunctions and core symptoms of metabolic syndrome. Conclusion: Our study showed DE of proteins involved in metabolic and cellular processes, indicative of impaired hepatic functions which may contribute to the onset and progression of various diseases (e.g. NASH, NAFLD, hepatocarcinoma) in mouse offspring developed following ART. Moreover, impaired hepatic metabolism was associated with obesity, glucose intolerance, insulin resistance and dyslipidaemia which are core symptoms of metabolic syndrome and risk factor for diabetes and cardiovascular diseases in adult ART offspring. Thus, we provide evidence of Assisted Reproductive Technologies is a risk factor for perturbation of hepatic proteome, associated with the increased predisposition to liver diseases and metabolic syndrome in adulthood.
