A Cell-Penetrant Peptide Disrupting the Transcription Factor CP2c Complexes Induces Cancer-Specific Synthetic Lethality.

Despite advances in precision oncology, cancer remains a global public health issue. In this report, proof-of-principle evidence is presented that a cell-penetrable peptide (ACP52C) dissociates transcription factor CP2c complexes and induces apoptosis in most CP2c oncogene-addicted cancer cells through transcription activity-independent mechanisms. CP2cs dissociated from complexes directly interact with and degrade YY1, leading to apoptosis via the MDM2-p53 pathway.

Hormone autocrination by vascularized hydrogel delivery of ovary spheroids to rescue ovarian dysfunctions.

The regeneration potential of implantable organ model hydrogels is applied to treat a loss of ovarian endocrine function in women experiencing menopause and/or cancer therapy. A rat ovariectomy model is used to harvest autologous ovary cells while subsequently producing a layer-by-layer form of follicle spheroids. Implantation of a microchannel network hydrogel with cell spheroids [vascularized hydrogel with ovarian spheroids (VHOS)] into an ischemic hindlimb of ovariectomized rats significantly aids the recovery of endocrine function with hormone release, leading to full endometrium regeneration.

Identification of Serum Biomarkers for Diagnosis of Endometriosis Using Multiplex Immunoassays.

Endometriosis is a common gynecologic disorder characterized by chronic pelvic pain, dysmenorrhea, and infertility. Although this condition places significant financial burden on the healthcare system and negatively affects patient's quality of life, the pathophysiology of the disease remains unclear, and noninvasive diagnostic methods are insufficient. The object of this study was to identify potential biomarkers for endometriosis from peripheral blood.

Operative hysteroscopy-assisted pregnancy termination after failed surgical abortion in missed abortion of woman with complete septate uterus.

First trimester surgical abortion is an effective and safe procedure. Although its failure is uncommon, congenital uterine anomaly may be considered as one of the etiologic factors in such cases. Here, we report a rare case of surgical abortion failure that was successfully managed by operative hysteroscopy-assisted dilatation and evacuation (D&E) under ultrasound guidance in a woman with complete uterine septum.

Polycystic ovarian morphology is associated with primary dysmenorrhea in young Korean women.

Objective: This study was aimed at identifying a correlation between polycystic ovarian morphology (PCOM) and the severity of primary dysmenorrhea in young Korean women.

Methods: A total of 592 patients who visited a tertiary hospital from March 2008 to March 2015 for dysmenorrhea were examined. After excluding those with secondary causes of menstrual pain (for example, myoma, adenomyosis, endometriosis, and pelvic inflammatory disease), 361 women were recruited and retrospectively analyzed.

Clinical factors and ultrasound parameters to predict successful vaginal delivery following labour induction.

Morbidity and complications are higher with caesarean delivery after labour induction. We aimed to evaluate which maternal/neonatal pregnancy characteristics and ultrasound parameters are useful in predicting successful vaginal delivery following labour induction. In this retrospective observational study, several maternal and foetal characteristics were studied in 197 primigravidae women at 38 or more gestational weeks before induction.

MiR-150-5p May Contribute to Pathogenesis of Human Leiomyoma via Regulation of the Akt/p27 Pathway In Vitro.

Uterine leiomyoma is found in ~50-80% of women of a reproductive age and is the most common reason for hysterectomy. Recently, posttranscriptional gene silencing by microRNAs (miRs) has been reported as a mechanism for regulating gene expression stability in the pathogenesis of uterine leiomyomas. In this study, miR microarray analysis of leiomyomas and paired myometrial tissue revealed numerous aberrantly expressed miRs, including miR-150.

Comparison of congenital malformations among babies born after administration of letrozole or clomiphene citrate for infertility treatment in a Korean cohort.

This retrospective study investigated and compared the incidence of congenital foetal anomalies after letrozole versus clomiphene citrate (CC) administration for infertility treatment. Data from 142 newborns were included: letrozole group, n = 83; CC group, n = 61. Congenital anomalies were found in 7.

Postoperative urinary symptoms after transobturator tape in normal-weight compared with overweight and obese woman.

Objectives: To examine the clinical outcome of obesity in women who underwent the transobturator tape procedure for stress urinary incontinence and to compare postoperative urinary symptoms after transobturator tape surgery between normal-weight women and overweight and obese women.

Methods: We performed a retrospective cohort study of the risk of postoperative urinary symptoms, including recurrence after transobturator tape surgery, in normal-weight women compared with overweight and obese women at our institution from January 2009 through October 2011. We compared the body mass index (BMI) among the four groups.

Cleavage of molybdopterin synthase MoaD-MoaE linear fusion by JAMM/MPN domain containing metalloprotease DR0402 from Deinococcus radiodurans.

Molybdenum cofactor (Moco), molybdopterin (MPT) complexed with molybdenum, is an essential cofactor required for the catalytic center of diverse enzymes in all domains of life. Since Moco cannot be taken up as a nutrient unlike many other cofactors, Moco requires de novo biosynthesis. During the synthesis of MPT, the sulfur atom on the C-terminus of MoaD is transferred to cyclic pyranopterin monophosphate (cPMP) which is bound in the substrate pocket of MoaE.

In-bag power morcellation technique in single-port laparoscopic myomectomy.

Objective: This study introduces and evaluates the feasibility, safety, and surgical outcomes of the in-bag power morcellation technique during single-port assisted (SPA) laparoscopic myomectomy in comparison with manual scalpel morcellation.

Methods: This is a retrospective review of a total of 58 patients who underwent SPA laparoscopic myomectomy employing in-bag power morcellation (n=27) or manual scalpel morcellation (n=31), performed between December 2014 and December 2016. Surgical outcomes, including total operation time, estimated blood loss, postoperative hemoglobin changes, postoperative hospital stay, postoperative pain (visual analog scale), perioperative and postoperative complications were evaluated.

The inability of Bacillus licheniformis perR mutant to grow is mainly due to the lack of PerR-mediated fur repression.

PerR, a member of Fur family protein, is a metal-dependent HO sensing transcription factor that regulates genes involved in peroxide stress response. Industrially important bacterium Bacillus licheniformis contains three PerR-like proteins (PerR, PerR2, and PerR3) compared to its close relative Bacillus subtilis. Interestingly, unlike other bacteria including B.

The difference in in vivo sensitivity between Bacillus licheniformis PerR and Bacillus subtilis PerR is due to the different cellular environments.

PerR, a member of Fur family of metal-dependent regulators, is a major peroxide sensor in many Gram positive bacteria, and controls the expression of genes involved in peroxide resistance. Bacillus licheniformis, a close relative to the well-studied model organism Bacillus subtilis, contains three PerR-like proteins (PerR, PerR2 and PerR3) in addition to Fur and Zur. In the present study, we characterized the role of PerR in B.

Bacillus licheniformis Contains Two More PerR-Like Proteins in Addition to PerR, Fur, and Zur Orthologues.

The ferric uptake regulator (Fur) family proteins include sensors of Fe (Fur), Zn (Zur), and peroxide (PerR). Among Fur family proteins, Fur and Zur are ubiquitous in most prokaryotic organisms, whereas PerR exists mainly in Gram positive bacteria as a functional homologue of OxyR. Gram positive bacteria such as Bacillus subtilis, Listeria monocytogenes and Staphylococcus aureus encode three Fur family proteins: Fur, Zur, and PerR.

Staphylococcus aureus PerR Is a Hypersensitive Hydrogen Peroxide Sensor using Iron-mediated Histidine Oxidation.

In many Gram-positive bacteria PerR is a major peroxide sensor whose repressor activity is dependent on a bound metal cofactor. The prototype for PerR sensors, the Bacillus subtilis PerRBS protein, represses target genes when bound to either Mn(2+) or Fe(2+) as corepressor, but only the Fe(2+)-bound form responds to H2O2. The orthologous protein in the human pathogen Staphylococcus aureus, PerRSA, plays important roles in H2O2 resistance and virulence.
