FOXF2 expression triggered by endocrine therapy orchestrates therapeutic resistance through reorganization of chromatin architecture in breast cancer.

Patients with estrogen receptor-positive (ER+) breast cancer require long-term endocrine therapy. However, endocrine resistance remains a critical issue to be addressed. Herein, we show that ERα repressed FOXF2 transcription in ER+ breast cancer through H3K27me3 modification, therefore endocrine therapy triggered FOXF2 transcription via loss of H3K27me3.

Manipulating fluorescence by photo-switched spin-state conversions in an iron(ii)-based SCO-MOF.

Manipulating fluorescence by photo-switched spin-state conversions is an attractive prospect for applications in smart magneto-optical materials and devices. The challenge is how to modulate the energy transfer paths of the singlet excited state by light-induced spin-state conversions. In this work, a spin crossover (SCO) Fe-based fluorophore was embedded into a metal-organic framework (MOF) to tune the energy transfer paths.

Anti-inflammatory effect and component analysis of Chaihu Qingwen granules.

Comparison of pregnancy outcomes of letrozole-induced frozen-thawed embryo transfer cycles in PCOS women with two different abnormal ovulation patterns: A retrospective cohort study.

No studies have been conducted on the impact of different types of ovulatory dysfunction on the outcomes of frozen-thawed embryo transfers (FETs) in a letrozole-stimulated cycle in women with polycystic ovarian syndrome (PCOS). This study aimed to compare whether pregnancy outcomes of the letrozole-induced protocol in FET cycles differed between oligo-ovulatory and anovulatory women with PCOS. In a retrospective cohort study, women with PCOS who had undergone letrozole-induced FET at a university-affiliated fertility clinic from February 2014 to October 2020 were identified.

Premature timing of progesterone luteal phase support initiation did not negatively impact live birth rates in modified natural frozen thawed embryo transfer cycles.

Study Question: In a modified natural cycle frozen-thawed embryo transfer (mNC-FET), does the premature timing of progesterone luteal phase support (LPS) initiation 24 h following human chorionic gonadotropin (hCG) trigger impact live birth?

Summary Answer: Premature LPS initiation did not negatively affect the live birth rate (LBR) in mNC-FET cycles compared with conventional LPS initiation 48 h after hCG triggering.

What Is Known Already: During natural cycle FET, human chorionic gonadotropin is routinely used to mimic endogenous luteinizing hormone (LH) surge to induce ovulation, which allows more flexibility in embryo transfer scheduling, thus relieving the burden of multiple visits by patients and laboratory workloads, which is also known as mNC-FET. Moreover, recent data demonstrates that ovulatory women undergoing natural cycle FETs have a lower risk of maternal and fetal complications due to the essential role of the corpus luteum in implantation, placentation and pregnancy maintenance.

Effect of gene polymorphisms on the clinical efficacy of carboplatin therapy in Han patients with ovarian cancer.

Gene polymorphisms have a close relationship with the clinical effects of carboplatin for ovarian cancer. Here, we investigated the relationship between and genotypes and the clinical efficacy of carboplatin in ovarian cancer, thereby clarifying the unidentified genetic factors that influence the efficacy of carboplatin in ovarian cancer. Based on the above purposes, we used Sequenom Mass ARRAY technology to detect and gene polymorphisms in 127 patients with carboplatin-treated ovarian cancer.

Anxiety and depression among pregnant women undergoing IVF-ET and WeChat group peer support during the COVID-19 pandemic: Study protocol for a randomized controlled trial.

Introduction: The psychological well-being of pregnant women following assisted reproductive has increasingly gained attention in recent years. Anxiety and depression may be associated to pregnancy outcomes. This study aims to determine whether peer support and the WeChat group platform will reduce anxiety and depression among in vitro fertilization and embryo transfer (IVF-ET) women.

Impact of progesterone-free luteal phase support following natural cycle frozen embryo transfer: Study protocol for a multicenter, non-inferiority, randomized controlled trial.

Introduction: Nowadays, frozen-thawed embryo transfer (FET) has become one of the standard treatments for infertility in the field of assisted reproductive technology (ART). Natural cycle FET (NC-FET) has many advantages, such as simplicity and economics, no effect on patients' menstrual cycles, estrogen and progesterone levels, as well as no interference in endometrial growth and transformation, which is aligned with the natural physiological state of embryo implantation. Nonetheless, there is a controversy regarding the need for luteal phase support (LPS) during NC-FET cycles.

Short (seven days) versus standard (fourteen days) oestrogen administration in a programmed frozen embryo transfer cycle: a retrospective cohort study.

Research Question: What influence does seven days of oestrogen administration versus fourteen days have on the reproductive outcomes of frozen-thawed embryo transfer (FET) in programmed endometrial preparation cycles?

Design: In a retrospective study, conducted at a university-affiliated tertiary hospital, a total of 2628 infertile patients (4142 FET cycles) were divided into one of two groups between January 2014 and December 2020: group A (n = 1406, seven days of oestrogen before progesterone (P4) supplementation) and group B (n = 2716, fourteen days of oestrogen before P4 supplementation). The primary outcome was cumulative live birth rate (CLBR). Secondary outcomes were other pregnancy-related outcomes, maternal and neonatal complications.

The role of CEMIP in tumors: An update based on cellular and molecular insights.

CEMIP was initially identified as an inner-ear specific protein in which three-point mutations cause folding changes in protein structure associated with non-syndromic hearing loss. CEMIP was also involved in other cellular activities, such as hyaluronan depolymerization independent of CD44 and other hyaluronidases. Growing evidence has demonstrated that CEMIP is involved in the progression of various tumors.
