A Golgi-Targeted Platinum Complex Plays a Dual Role in Autophagy Regulation for Highly Efficient Cancer Therapy.

Regulating autophagy to control the homeostatic recycling process of cancer cells is a promising anticancer strategy. Golgi apparatus is a substrate of autophagy but the Golgi-autophagy (Golgiphagy) mediated antitumor pathway is rarely reported. Herein, we have developed a novel Golgi-targeted platinum (II) complex Pt3, which is ca.

Mesenchymal stem cell-derived extracellular vesicles in skin wound healing: roles, opportunities and challenges.

Skin wounds are characterized by injury to the skin due to trauma, tearing, cuts, or contusions. As such injuries are common to all human groups, they may at times represent a serious socioeconomic burden. Currently, increasing numbers of studies have focused on the role of mesenchymal stem cell (MSC)-derived extracellular vesicles (EVs) in skin wound repair.

Tertiary lymphoid structures and cytokines interconnections: The implication in cancer immunotherapy.

Tertiary lymphoid structures (TLSs) are organized aggregates of lymphocytes and antigen-presenting cells that develop in non-lymphoid tissues during chronic inflammation, resembling the structure and features of secondary lymphoid organs. Numerous studies have shown that TLSs may be an important source of antitumor immunity within solid tumors, facilitating T cell and B cell differentiation and the subsequent production of antitumor antibodies, which are beneficial for cancer prognosis and responses to immunotherapy. The formation of TLSs relies on the cytokine signaling network between heterogeneous cell populations, such as stromal cells, lymphocytes and cancer cells.

Serum antiphospholipid antibody status may not be associated with the pregnancy outcomes of patients undergoing in vitro fertilization.

Background: Antiphospholipid syndrome (APS) is an autoimmune disease that is associated with recurrent pregnancy loss. It is still controversial whether the presence of antiphospholipid antibodies (aPL) in the serum of patients with in vitro fertilization-embryo transfer (IVF-ET) has a negative effect on the outcomes. In view of the discrepancies, a meta-analysis of the published data was performed to explore the relationship of aPL and IVF-ET outcomes.

CNOT6/6L-mediated mRNA degradation in ovarian granulosa cells is a key mechanism of gonadotropin-triggered follicle development.

CCR4-NOT deadenylase is a major regulator of mRNA turnover. It contains two heterogeneous catalytic subunits CNOT7/8 and CNOT6/6L in vertebrates. The physiological function of each catalytic subunit is unclear due to the gene redundancy.

A positive COX-2/IL-1β loop promotes decidualization by upregulating CD82.

A successful pregnancy requires sufficient decidualization of endometrial stromal cells (ESCs). CD82, a metastasis suppressor, is a critical regulator for trophoblast invasion but the effect in decidualization was largely unknown. Here we reported that there was a high level of CD82 in DSC by the immunohistochemistry staining and flow cytometer analysis.

Objective: To analyze the functions of the two extracellular loops of occludin in the tight junction of TM4 cells in mice.

Methods: Using genetic engineering, we separately or simultaneously deleted two extracellular loops of occludin, cloned the three occludin genes without extracellular loops into the pcDNA3.1 expression vector, and transfected them into TM4 cells.

Effect of interventional embolization treatment for hydrosalpinx on the outcome of in vitro fertilization and embryo transfer.

To explore the effect of interventional embolization treatment for hydrosalpinx on the outcome of in vitro fertilization and embryo transfer (IVF-ET).During the period from January 2013 to January 2015, a total of 129 patients with unilateral or bilateral hydrosalpinx were treated with IVF-ET and selected for retrospective analysis. Seventy-three patients (intervention group) with unilateral or bilateral hydrosalpinx were treated with fallopian tube embolization, which was followed by IVF-ET.

Objective: To study the inhibitory effect of small interference RNA (siRNA) targeting cyclin A2 gene on the growth of osteosarcoma MG-63 and human normal skin fibroblast HSF cells and to explore whether cyclin A2 siRNAs could become a useful tool in the treatment of osteosarcoma.

Methods: Three pairs of siRNAs targeting cyclin A2 mRNA and a pair of nonsense siRNA were designed according to the current criteria. SiRNAs were chemically synthesized and purified.

[Deletion of the env region in HERV-H-X gene and its expression in colon cancer].

Background & Objective: We have identified a novel gene HERV-H-X from colon cancer tissue recently. This research was to analyze the deletion of the env region of HERV-H-X, to compare its expression with that of the env open reading frames (ORFs) in other HERV-H proviruses, and to study its differential expression in colon cancer and normal colon tissues.

Methods: Multiple alignments were performed for HERV-H-X and 3 other HERV-H proviruses (HERV-H/env62, HERV-H/env60, and HERV-H/env59) containing intact env ORF.
