The G protein-coupled receptor APJ and its cognate ligand, apelin, are widely expressed throughout human body. They are implicated in different key physiological processes such as angiogenesis, cardiovascular functions, fluid homeostasis and energy metabolism regulation. Recently, a new endogenous peptidic ligand of APJ, named Elabela, has been identified and shown to play a crucial role in embryonic development. In addition, increasing evidences show that Elabela is also intimate associated with a large number of physiological processes in adulthood...

Intrauterine adhesion (IUA) is characterized by endometrial fibrosis, which ultimately leads to menstrual abnormalities, infertility and recurrent miscarriages. The Shh/Gli2 pathway plays a critical role in tissue fibrogenesis and regeneration; Gli2 activation induces profibrogenic effects in various tissues, such as the liver and kidney. However, the role of Gli2 in endometrial fibrosis remains unknown. The purpose of this study was to test the hypothesis that activated Gli2 promotes endometrial fibrosis. Endometrial samples from moderate and severe IUA patients exhibited significantly enhanced expression of Gli2 compared with normal endometrial samples and mild IUA samples...

The tissue kallikrein‑kinin system (KKS) is an endogenous multiprotein metabolic cascade which is implicated in the homeostasis of the cardiovascular, renal and central nervous system. Human tissue kallikrein (KLK1) is a serine protease, component of the KKS that has been demonstrated to exert pleiotropic beneficial effects in protection from tissue injury through its anti‑inflammatory, anti‑apoptotic, anti‑fibrotic and anti‑oxidative actions. Mesenchymal stem cells (MSCs) or endothelial progenitor cells (EPCs) constitute populations of well‑characterized, readily obtainable multipotent cells with special immunomodulatory, migratory and paracrine properties rendering them appealing potential therapeutics in experimental animal models of various diseases...

Investigations of anti-HIV-1 human hematopoietic stem/progenitor cell (HSPC)-based gene therapy have been performed by HIV-1 challenge after the engraftment of gene-modified HSPCs in humanized mouse models. However, the clinical application of gene therapy is to treat HIV-1-infected patients. Here, we developed a new method to investigate an anti-HIV-1 HSPC-based gene therapy in humanized mice previously infected with HIV-1. First, humanized mice were infected with HIV-1. When plasma viremia reached >107 copies/mL 3 weeks after HIV-1 infection, the mice were myeloablated with busulfan and transplanted with anti-HIV-1 gene-modified CD34+ HSPCs transduced with a lentiviral vector expressing two short hairpin RNAs (shRNAs) against CCR5 and HIV-1 long terminal repeat (LTR), along with human thymus tissue under the kidney capsule...

Hematopoietic stem cell transplantation (SCT) recipients are exposed to a large amount of anti-cancer drugs, immunosuppressors, and irradiation during the peri-SCT period. Thus, they have to overcome serious adverse events related to unavoidable but toxic procedures, including organ disorders. In particular, acute kidney injury (AKI) is one of the most critical complications, because it influences the mortality of patients. A few patients who survive AKI may develop nephrotic syndrome, and precedent AKI is also closely associated with chronic and progressive loss of the renal function in post-SCT patients...

Slit guidance ligand 2 (SLIT2) is a large, secreted protein which binds roundabout (ROBO) receptors on multiple cell types including neurons and kidney podocytes. SLIT2-ROBO2 mediated signaling regulates neuronal migration and ureteric bud (UB) outgrowth during kidney development as well as glomerular filtration in adult kidneys. Additionally, SLIT2 binds Gremlin, an antagonist of bone morphogenetic proteins (BMPs), and BMP-Gremlin signaling also regulates UB formation. However, direct crosstalk between the ROBO2-SLIT2 and BMP-Gremlin signaling pathways has not been established...

In a previous study, we found that DNAJB8, a heat shock protein (HSP) 40 family member is expressed in kidney cancer stem-like cells (CSCs)/cancer-initiating cells (CICs) and that it has a role in the maintenance of kidney CSCs/CICs. Heat shock factor (HSF) 1 is a key transcription factor for responses to stress including heat shock, and it induces HSP family expression through activation by phosphorylation. In this study, we therefore examined whether heat shock (HS) induces CSCs/CICs. We treated the human kidney cancer cell line ACHN with HS, and found that HS increased side population (SP) cells...

We tested the hypothesis that allogenic adipose-derived mesenchymal stem cells (ADMSCs) alleviated brain death (BD)-induced remote organ damage and events of post heart-transplant acute rejection. To determine the impact of BD on remote organ damage, adult-male F344 rats (n=24) were categorized sham-control (SC), BD and BDMSC (allogenic ADMSC/1.2 × 106 cells/derived from F344 by intravenous transfusion 3 h after BD procedure). To determine the protective effect of allogenic ADMSCs, animals (n=8/each group in F344/Lewis) were categorized into groups BD-T(F344 heart transplanted into Lewis by 6h after BD), BD-TMSC(D1/3) (BD induction for 6h then heart transplantation, and allogenic ADMSCs transfusion at days 1 and 5 after heart transplantation), BD-TMSC(3h) (BD + ADMSC/1...

BACKGROUND: Studies on living donors from the donors' perspective show that the donation process involves both positive and negative feelings involving vulnerability. Qualitative studies of living kidney, liver, and allogeneic hematopoietic stem cell donors have not previously been merged in the same analysis. Therefore, our aim was to synthesize current knowledge of these donors' experiences in order to deepen understanding of the meaning of being a living donor for the purpose of saving or extending someone's life...

BACKGROUND: Cisplatin is a highly effective antitumor agent whose clinical application is limited by its nephrotoxicity, which is associated with high mortality and morbidity rates. We aimed to study the protective role of silymarin and mesenchymal stem cells as a therapeutic tool of cisplatin nephrotoxicity. MATERIALS AND METHODS: We injected rats with cisplatin in a dose of 5mg/kg body weight for 5 days to induce acute renal failure (ARF). Silymarin was administrated 6 hours before cisplatin injection and mesenchymal stem cells were injected 24 hours after cisplatin-induced ARF...

Multi-functional nanoshuttles for remotely targeted and on-demand delivery of therapeutic molecules and imaging to defined tissues and organs hold great potentials in personalized medicine, including precise early diagnosis, efficient prevention and therapy without toxicity. Yet, in spite of 25 years of research, there are still no such shuttles available. To this end, we have designed magnetic and gold nanoparticles (NP)-embedded silica nanoshuttles (MGNSs) with nanopores on their surface. Fluorescently labeled Doxorubicin (DOX), a cancer drug, was loaded in the MGNSs as a payload...

Ficus burtt-davyi (Moraceae) is a medicinal plant species indigenous to Southern Africa. In this study, a phytochemical and cytotoxic investigation on F. burtt-davyi was conducted to evaluate its ethno-medicinal use. The phytochemical study of the fruits yielded triterpenoids (lupeol and α-amyrin). The cytotoxic evaluation was done on the methanolic extracts and selected compounds, lupeol, α-amyrin, lupeol acetate and (+)-catechin isolated from F. burtt-davyi stem bark and fruits. The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) cell viability assay was carried out against two human cancer cell lines, breast adenocarcinoma (MCF-7) and colorectal adenocarcinoma (Caco-2), and normal human embryonic kidney cells (HEK293)...

Successful isolation of human endometrial stem cells from menstrual blood, namely menstrual blood-derived endometrial stem cells (MenSCs), has provided enticing alternative seed cells for stem cell-based therapy. MenSCs are enriched in the self-regenerative tissue, endometrium, which shed along the periodic menstrual blood and thus their acquisition involves no physical invasiveness. However, the impact of the storage duration of menstrual blood prior to stem cell isolation, the age of the donor, the number of passages on the self-renewing of MenSCs, the paracrine production of biological factors in MenSCs and expression of adhesion molecules on MenSCs remain elusive...

Dengue virus (DENV) infection is a worldwide public health problem, which can cause severe dengue hemorrhagic fever (DHF) and life-threatening dengue shock syndrome (DSS). There are currently no anti-DENV drugs available, and there has been an intensive search for effective anti-DENV agents that can inhibit all four DENV serotypes. In this study, we tested whether vivo-morpholino oligomers (vivo-MOs), whose effect on DENV infection has not previously been studied, can inhibit DENV infection. Vivo-MOs were designed to target the top of 3' stem-loop (3' SL) in the 3' UTR of the DENV genome and tested for inhibition of DENV infection in monkey kidney epithelial (Vero) cells and human lung epithelial carcinoma (A549) cells...

Nephrotic syndrome (NS) is a rare complication of hematopoietic cell transplantation (HCT) and is thought to represent a renal manifestation of chronic graft-versus-host disease (cGVHD). Glomerulopathies occur less often in recipients of autologous as compared to allogeneic HCT and, in this setting, renal pathology is less well characterized. This case report describes a 54-year-old man admitted for the evaluation of a nephrotic-range proteinuria. His past medical history included a ? light-chain secreting multiple myeloma (MM) for which he underwent autologous HCT...
