The human uterus consists of the inner endometrium, the myometrium, and the outer serosa. Knowledge of the function of the uterus in health and disease is relevant to reproduction, fertility, embryology, gynaecology, endocrinology, and onco…

Chronic pelvic pain (CPP) is one of the most common chronic pain problems experienced by women, with prevalence rates comparable to asthma and back pain. However, it is poorly understood and causative pathology is only seldom found. We aime…

Endometrial cancer is the commonest gynecological cancer, with an incidence predicted to escalate by a further 50-100% before 2025, due to the rapid rise in risk factors such as obesity and increased life expectancy. Endometrial cancer asso…

Telomeres at the termini of human chromosomes are shortened with each round of cell division due to the "end replication problem" as well as oxidative stress. During carcinogenesis, cells acquire or retain mechanisms to maintain telomeres t…

STUDY QUESTION: Is endometriosis associated with abnormally located endometrial basalis-like (SSEA1+/SOX9+) cells in the secretory phase functionalis and could they contribute to ectopic endometriotic lesion formation? SUMMARY ANSWER: Wome…

Table S1. Output from bioinformatics analysis showing differential expression of genes encoding NK cell receptors and ligands in secretory phase endometrium from endometriosis patients when compared with the endometrium of control women wit…

Table S2. The differentially expressed genes in post ovulatory eutopic endometrium of baboons 6 months after induction of endometriosis (n = 4) compared with the same of control animals (n = 4) published in Additional file 3: Table S2, in A…

The human endometrium is a highly regenerative organ undergoing over 400 cycles of shedding and regeneration over a woman's lifetime. Menstrual shedding and the subsequent repair of the functional layer of the endometrium is a process uniqu…

The cyclical process of regeneration of the endometrium suggests that it may contain a cell population that can provide daughter cells with high proliferative potential. These cell lineages are clinically significant as they may represent c…

BACKGROUND: Endometriosis is a common condition associated with growth of endometrial-like tissue beyond the uterine cavity. Previous reports have suggested a role for uNK cells in the pathogenesis of endometriosis postulating that survival…

STUDY QUESTION: Are there any phenotypic and structural/architectural changes in the vessels of endometrium and superficial myometrium during the normal menstrual cycle in healthy women and those with heavy menstrual bleeding (HMB)? SUMMAR…

Heavy menstrual bleeding (HMB) is a common gynecological complaint with multiple etiologies and diverse pathophysiological origins. This review discusses HMB with reference to the recently proposed PALM-COEIN classification system for abnor…

STUDY QUESTION: Can bioinformatics analysis of publically available microarray datasets be utilized in identifying potentially important transcription factors (TF) in the hormonal regulation of the endometrium? SUMMARY ANSWER: Systems inte…

STUDY QUESTION: How does the smooth muscle content and differentiation stage of vascular smooth muscle cells (VSMCs) in endometrial blood vessels change according to the different phases of the menstrual cycle and is this altered in women w…

Endometriosis is a common, chronic inflammatory disease defined by the presence of extrauterine endometrial tissue. The aetiology of endometriosis is complex and multifactorial, where several not fully confirmed theories describe its pathog…

Study question: To compare the pregnancy rate in patients submitted to FET (Frozen Embryos Transfer) of cleavage stage embryos (Group 1), or at the blastocyst stage (Group 2). Summary answer: Our data showed that the transfer of frozen blas…

BACKGROUND: In order to test our hypothesis that endometriosis is associated with abnormal expression of telomerase and telomere lengthening in endometrium, we assessed endometrial expression of the human telomerase enzyme and telomere leng…

By protecting eukaryotic linear chromosomal ends, telomeres are critical in maintaining chromosomal integrity and cellular stability. The expression of telomerase correlates specifically with cellular proliferation, and most endometrial can…

BACKGROUND: To test our hypothesis that eutopic secretory phase endometrium from women with endometriosis is similar to proliferative phase endometrium from fertile women without endometriosis, we explored the expression of regulators of ce…

In women, a single dose of the antiprogestin mifepristone (RU486) in the secretory phase rapidly renders the endometrium unreceptive and is followed by endometrial breakdown and menstruation within 72 h. This model provides a system to iden…
