ADGRG1 enriches for functional human hematopoietic stem cells following ex vivo expansion-induced mitochondrial oxidative stress.

The heterogeneity of human hematopoietic stem cells (HSCs) and hematopoietic progenitor cells (HPCs) under stress conditions such as ex vivo expansion is poorly understood. Here, we report that the frequencies of SCID-repopulating cells were greatly decreased in cord blood (CB) CD34+ HSCs and HPCs upon ex vivo culturing. Transcriptomic analysis and metabolic profiling demonstrated that mitochondrial oxidative stress of human CB HSCs and HPCs notably increased, along with loss of stemness.

Effect of extruded starches on the structure, farinograph characteristics and baking behavior of wheat dough.

Extruded wheat starch (ES) was obtained by a single-screw extruder to determine its effect on the farinograph, structural properties and baking behaviors of wheat dough. XRD analysis showed that increasing extrusion temperature made the crystalline peaks less pronounced due to the partial gelatinization. In terms of FTIR results, the molecular order of extruded starch was lower than that of native starch.

RXR Negatively Regulates Ex Vivo Expansion of Human Cord Blood Hematopoietic Stem and Progenitor Cells.

Ex vivo expansion of human cord blood (CB) hematopoietic stem cells (HSCs) is one approach to overcome limited numbers of HSCs in single CB units. However, there is still no worldwide acceptable HSC ex vivo expansion system. A main reason is that we still have very limited knowldege regarding mechanisms underlying maintenance and expansion of CB HSCs.

Preeclampsia serum increases CAV1 expression and cell permeability of human renal glomerular endothelial cells via down-regulating miR-199a-5p, miR-199b-5p, miR-204.

Introduction: To gain insight into mechanisms of preeclampsia (PE)-dependent proteinuria, this study focused on whether preeclampsia serum (PES) could induce hyperpermeability in human renal glomerular endothelial cells (HRGECs) via the miRNAs-Caveolin-1 (CAV-1)-dependent pathway.

Methods: Bioinformatics approach was used to identify miRNAs targeting CAV1. Normal pregnancy serum (NPS) and severe PES were used to treat HRGECs monolayer to demonstrate if PES could induce the expression of identified miRNAs.

MELK promotes Endometrial carcinoma progression via activating mTOR signaling pathway.

Background: Endometrial carcinoma (EC) is one of the most common gynecological malignancies among women. Maternal embryonic leucine Zipper Kinase (MELK) is upregulated in a variety of human tumors, where it contributes to malignant phenotype and correlates with a poor prognosis. However, the biological function of MELK in EC progression remains largely unknown.

A long noncoding RNAs signature to improve survival prediction in endometrioid endometrial cancer.

Purpose: The dysregulation of long noncoding RNAs (lncRNAs) has been reported to be correlated to carcinogenesis and cancer progression. Endometrial cancer (EC), arising from the endometrium or the inner lining of the uterus, is one of the most common gynecological malignancies. We aim to explore the prognostic value of the lncRNAs in patients with endometrioid endometrial cancer (EEC) and to identify the potential lncRNA signature for predicting survival of patients with EEC.

Preeclampsia serum induces human glomerular vascular endothelial cell hyperpermeability via the HMGB1-Caveolin-1 pathway.

To explore new ideas about the pathogeny of preeclampsia (PE) proteinuria, this study focused on whether severe PE serum (PES) could induce high-molecular-weight protein (HMWP) hyperpermeability in glomerular endothelial cells (GEC) via the HMGB1-Caveolin-1 (CAV-1) pathway. Normal pregnancy serum (NPS) and severe PES were used to treat primary human GEC monolayer for 24 h. The CAV-1 inhibitor methyl-beta-cyclodextrin (MBCD), the HMGB1 inhibitor glycyrrhizicacid (GA), recombinant HMGB1 (rHMGB1) were also used to treat GEC monolayer that were stimulated by NPS or severe PES.

RelB/NF-κB links cell cycle transition and apoptosis to endometrioid adenocarcinoma tumorigenesis.

Dysfunction of nuclear factor-κB (NF-κB) signaling has been causally associated with numerous human malignancies. Although the NF-κB family of genes has been implicated in endometrial carcinogenesis, information regarding the involvement of central regulators of NF-κB signaling in human endometrial cancer (EC) is limited. Here, we investigated the specific roles of canonical and noncanonical NF-κB signaling in endometrial tumorigenesis.

Hypoxic trophoblast HMGB1 induces endothelial cell hyperpermeability via the TRL-4/caveolin-1 pathway.

High mobility group box 1 (HMGB1) plays an important role in the pathologic processes of endothelial permeability under oxidative stress. Trophoblast oxidative stress has been implicated in the pathophysiology of preeclampsia (PE). HMGB1 serum levels are increased in PE.

Preeclampsia serum-induced collagen I expression and intracellular calcium levels in arterial smooth muscle cells are mediated by the PLC-γ1 pathway.

In women with preeclampsia (PE), endothelial cell (EC) dysfunction can lead to altered secretion of paracrine factors that induce peripheral vasoconstriction and proteinuria. This study examined the hypothesis that PE sera may directly or indirectly, through human umbilical vein ECs (HUVECs), stimulate phospholipase C-γ1-1,4,5-trisphosphate (PLC-γ1-IP3) signaling, thereby increasing protein kinase C-α (PKC-α) activity, collagen I expression and intracellular Ca(2+) concentrations ([Ca(2+)]i) in human umbilical artery smooth muscle cells (HUASMCs). HUASMCs and HUVECs were cocultured with normal or PE sera before PLC-γ1 silencing.

Syncytiotrophoblast-derived microparticle shedding in early-onset and late-onset severe pre-eclampsia.

Objective: To determine the concentration of syncytiotrophoblast-derived microparticles (STBMs) in the maternal circulation and the rate of syncytiotrophoblast apoptosis in the placenta of patients with early-onset and late-onset severe pre-eclampsia.

Methods: A prospective case-control study was conducted that enrolled 15 women with early-onset severe pre-eclampsia, 15 women with late-onset severe pre-eclampsia, and 10 women with normal pregnancies. Plasma STBM levels were measured by enzyme-linked immunosorbent assay, while placental levels of active caspase-3 were determined by western blotting.

A case of a naturally conceived pregnancy associated with multiple ovarian cysts in a patient with severe untreated primary hypothyroidism.

There are few reports of multiple ovarian cysts secondary to hypothyroidism, and multiple ovarian cysts associated with pregnancy most commonly occur in association with assisted reproductive technologies. Herein, we report a case of a naturally conceived pregnancy occurring 2 years after stopping treatment for primary hypothyroidism. The patient developed multiple ovarian cysts in the first trimester, and laboratory studies and ultrasonography were consistent with hypothyroidism.
