Mashup Score: 0
The impaired endometrial receptivity is a major factor contributing to infertility in patients with endometriosis (EM), but the underlying mechanism remains unclear. Our study aimed to investigate the role of Kruppel-like factor 15 (KLF15) in endometrial receptivity and its regulation in EM. We observed a significant decrease in KLF15 expression in the mid-secretory epithelial endometrial cells of EM patients compared to normal females without EM. To confirm the role of KLF15 in endometrial receptivity, we found a significantly reduced KLF15 expression and a significant decrease in embryo implantation number in the rat model via uterine horn infection with siRNA. This highlights the importance of KLF15 as a regulator receptivity. Furthermore, through ChIP-qPCR, we discovered that the progesterone receptor (PR) directly binds to KLF15 promoter regions, indicating that progesterone resistance may mediate the decrease in KLF15 expression in EM patients. Additionally, we found that the mid

Mashup Score: 2RISING STARS: Bumps and bacteria: influence of the maternal microbiota on pregnancy outcomes - 1 month(s) ago
During pregnancy, all major physiological systems undergo remarkable changes, driven largely by alterations in the maternal hormonal milieu. In healthy pregnancies, maternal cardiovascular and metabolic adaptation to pregnancy occurs to support fetal growth and maternal well-being. Impaired maternal adaptation to pregnancy is associated with a range of pregnancy complications, including gestational diabetes and preeclampsia. There is growing recognition of the importance of different maternal microbiota, including in the gut, vagina and oral cavity, in supporting normal maternal adaptations to pregnancy as well as evidence for microbial disturbances associating with pregnancy pathologies. Here, we aim to summarise emerging evidence demonstrating that differences in maternal microbiota associate with pregnancy outcomes and discuss potential therapeutic approaches under development that might restore an ‘optimal’ microbiome. In particular, we highlight recent work by ourselves and others

Mashup Score: 2Sex differences in the cardiovascular effects of GnRH analogues - 1 month(s) ago
The integral role of the hypothalamic–pituitary–gonadal axis in reproductive processes makes it a prime therapeutic target. By inhibiting sex steroid synthesis, gonadotropin-releasing hormone (GnRH) analogues are used in the management of cancers, benign neoplasms, infertility and gender dysphoria. However, the wide application of these therapeutics raises concerns regarding the unintended effects upon the cardiovascular system. In males with prostate cancer, GnRH analogues when used as an androgen deprivation therapy appear to increase the risk of cardiovascular disease, which is the leading cause of death in this population. Therefore, due to the utilisation of GnRH analogues across the lifespan and gender spectrum, this relationship merits discussion. Existing data suggest an association between GnRH analogues and major adverse cardiovascular events in males. Conversely, females receiving GnRH analogues for breast cancer treatment appear to be at an increased risk of developing hype

Mashup Score: 10Androgen therapy does not prevent bone loss and arterial calcifications in male rats with chronic kidney disease - 2 month(s) ago
Patients suffering from chronic kidney disease (CKD) often experience bone loss and arterial calcifications. It is unclear if hypogonadism contributes to the development of these complications and whether androgen therapy might prevent them. Male adult rats were randomized into four groups. The first group received standard chow (control), while three other groups were fed a 0.25% adenine/low vitamin K diet (CKD). Two CKD groups were treated with testosterone or dihydrotestosterone (DHT), whereas the control group and one CKD group received vehicle (VEH). CKD animals had 10-fold higher serum creatinine and more than 15-fold higher parathyroid hormone levels compared to controls. Serum testosterone levels were more than two-fold lower in the CKDVEH group compared to control + VEH and CKD + testosterone groups. Seminal vesicle weight was reduced by 50% in CKDVEH animals and restored by testosterone and DHT. CKD animals showed a low bone mass phenotype with decreased trabecular bone volum

Mashup Score: 1Hormonal changes in PCOS - 2 month(s) ago
Polycystic ovary syndrome (PCOS) is a common endocrinopathy occurring in reproductive-age women. Hyperandrogenism, polycystic ovaries, chronic anovulation, and metabolic aberrations are the common features in PCOS. Hormonal changes are causing pathological symptoms in women with PCOS. The various hormone alterations in PCOS have been demonstrated. Hormones, such as insulin, growth hormones (GH), ghrelin, LEAP-2, gonadotropin-releasing hormone (GnRH), insulin, the luteinizing hormone/follicle-stimulating hormone (LH/FSH) ratio, androgens, and estrogens, are all abnormal in PCOS women. These hormones are related to metabolic disorders, such as diabetes and insulin resistance, overweight and obesity, infertility, and disturbed menstrual cycle in PCOS patients. The pathological changes of these hormones, such as increased insulin, reduced GH, increased ghrelin, and leptin resistance, result in an increased prevalence of diabetes and obesity in PCOS women. A reduced GH, increased LEAP-2 lev

Mashup Score: 1Pituitary tumours: molecular and genetic aspects - 2 month(s) ago
‘Pituitary tumours’ is an umbrella term for various tumours originating from different regions of the hypothalamic–pituitary system. The vast majority of pituitary tumours are pituitary adenomas, also recently referred to as pituitary neuroendocrine tumours. The prevalence of clinically relevant pituitary adenomas is approximately 1 in 1000; other pituitary tumours such as craniopharyngioma and pituicytoma are comparatively very rare. This review addresses the molecular and genetic aspects of pituitary adenomas. We first discuss the germline genetic variants underlying familial pituitary tumours, which account for approximately 5% of all pituitary adenoma cases. This includes variants in established pituitary adenoma/hyperplasia predisposition genes (MEN1, PRKAR1A, AIP, CDKN1B, GPR101, SDHA, SDHB, SDHC, SDHD, SDHAF2) as well as emerging genetic associations. In addition, we discuss McCune–Albright syndrome which lies between the germline and somatic pituitary tumour genes as the causat

Mashup Score: 7Human gut microbiota and endocrinology: paradigm shift from genome to its regulation - 2 month(s) ago
Over the last two decades, it has become clear that the human gut microbiota, a complex community of bacteria, archaea, fungi and viruses, are a critical determinant of human health and disease. Microbiota-derived metabolites provide the host with energy, protect against pathogens, modulate immune and endocrine systems as well as the level of reactive oxygen species in the gut. It has come with no surprise that the human gut microbiota is also linked to the production, utilisation and regulation of host hormones. This implies that the gut microbiota is capable of influencing human behaviour, appetite regulation and metabolism as well as development and immunity. Many of the advances in the field of crosstalk between the gut microbiota and host health, disease and behaviours are generally based on DNA analyses of microbial populations and transplantation of monocultured commensal species to germ-free animals. Recent reports on the activity of the gut microbiota in gastrointestinal disea

Mashup Score: 13
Metabolic tests are vital to determine in vivo insulin sensitivity and glucose metabolism in preclinical models, usually rodents. Such tests include glucose tolerance tests, insulin tolerance tests, and glucose clamps. Although these tests are not standardized, there are general guidelines for their completion and analysis that are constantly being refined. In this review, we describe metabolic tests in rodents as well as factors to consider when designing and performing these tests.
