STUDY QUESTION: How does hCG signal in human endometrial stromal cells (ESCs) and what is its role in regulating ESC function? SUMMARY ANSWER: hCG signaling in ESCs activates the extracellular signal-regulated protein kinases 1 and 2 (Erk1…
The control of complement activation within embryo-endometrium environment is critical for embryo survival. Cell evasion from complement attack requires interaction of complement regulatory proteins (CRPs) with cell adhesion αvβ3 integrin. …
OBJECTIVE: To evaluate divalent metal transporter-1 (DMT1) expression in healthy women's and endometriosis patients' endometrium and to analyze DMT1 and ferritin light chain (Fn-L) expression modulation by iron overload and IL-1β in endomet…
OBJECTIVE: To evaluate the effect of iron overload on nuclear factor kappa-B (NF-κB) activation in human endometrial stromal cells (ESCs). DESIGN: Experimental study. SETTING: University hospital research laboratory. PATIENT(S): Ten heal…
The control of complement activation in the embryo-maternal environment has been demonstrated to be critical for embryo survival. Complement proteins are expressed in the human endometrium; however, the modulation of this expression by embr…
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…
OBJECTIVE: To update, analyze, and summarize the literature concerning nuclear factor-kappaB (NF-κB) participation in endometriosis pathophysiology. DESIGN: Review. RESULT(S): Nuclear factor-kappaB is physiologically activated in the huma…
BACKGROUND: The endometrium is a dynamic tissue whose changes are driven by the ovarian steroidal hormones. Its main function is to provide an adequate substrate for embryo implantation. Using microarray technology, several reports have pro…
OBJECTIVE: To evaluate nuclear factor kappaB (NF-κB) activation and NF-κB-p65 subunit activation, immunolocalization, and expression in the endometrium of healthy women and endometriosis patients throughout the menstrual cycle. DESIGN: Pro…
OBJECTIVE: To evaluate the role of nuclear factor-κB (NF-κB) in the pathogenesis of endometriosis. DESIGN: A literature search was conducted in PubMed to identify all relevant citations. RESULT(S): Our findings highlight the important rol…
Introduction: Endometriosis, defined as the growth of endometrial tissue outside \nthe uterine cavity is a common gynaecological disorder affecting 10-15% \nof women in their reproductive years. It is a major clinical problem causing in- \n…
Hydrosalpinx is usually associated with a low intrauterine pregnancy rate following restoration of tubal patency by microsurgery. The biochemical evaluation of pathologic tubes from 11 infertile patients showed the presence of estradiol (E2…
