Renal interstitial fibrosis is the most common process by which chronic kidney diseases progress to end-stage renal failure. Epithelial-to-mesenchymal transitions (EMTs) play a crucial role in the progression of renal interstitial fibrosis. A newly identified cytokine, interleukin-like EMT inducer (ILEI), has been linked to EMT in some diseases. However, the effects of ILEI on renal tubular EMT have not yet been well established. Here, we characterize the expression of ILEI in tubular EMT and describe the role and mechanism of ILEI in transforming growth factor beta 1 (TGF-β1)-induced renal tubular EMT...

Recent evidence suggested a positive correlation between environmental estrogens (EEs) and high incidence of abnormalities in male urogenital system, but the mechanism remains unclear. Diethylstilbestrol (DES) is a nonsteroidal synthetic estrogen that disrupts the morphology and proliferation of gubernaculum testis cells, but the underlying mechanism is unclear. In this study, mouse gubernaculum testis cells were pretreated with phospholipase C (PLC) inhibitor U-73122 and then treated with DES. The results demonstrated that U-73122 impaired DES-evoked intracellular Ca2+ mobilization in gubernaculum testis cells and inhibited DES-induced proliferation of gubernaculum testis cells...

Nuclear factor (erythroid-derived 2)-like 2 (NRF2) regulates antioxidant enzymes and phase II detoxifying enzymes, such as NAD(P)H: quinone oxidoreductase 1 (NQO1). Modified Xiaoyao powder (MXP) is most frequently used in the prevention and treatment of breast cancer in China. This study aimed to screen active components of MXP for antioxidant stress and chemoprevention, which depend on NRF2-NQO1 signalling pathway. A total of 25 monomeric compounds contained in MXP were screened using an antioxidant response element-luciferase reporter...

Despite a capacity for proliferation and an ability to differentiate into multiple cell types, in long-term culture and with ageing, stem cells show a reduction in growth, display a decrease in differentiation potential, and enter senescence without evidence of transformation. The Lin28a gene encodes an RNA-binding protein that plays a role in regulating stem cell activity, including self-renewal and differentiation propensity. However, the effect of the Lin28a gene on cultured human osteoprecursor cells is poorly understood...

Cervical cancer is one of the most common malignancies of the female reproductive system. Therefore, it is critical to investigate the molecular mechanisms involved in the development and progression of cervical cancer. In this study, we stimulated cervical cancer cells with 5-aza-2'-deoxycytidine (5-Aza-dC) and found that this treatment inhibited cell proliferation and induced apoptosis; additionally, methylation of p16 and O-6-methylguanine-DNA methyltransferase (MGMT) was reversed, although their expression was suppressed...

Coronary slow flow phenomenon (CSFP) is a coronary microvascular disorder with an increasing morbidity, and currently, available therapies are of limited clinical value for its cure. Hence, it is urgent to find a novel approach to CSFP treatment. Several studies show that endothelial dysfunction plays a critical role in the aetiology of CSFP. Telmisartan (TMST) is a clinically available anti-hypertensive medicine and has shown its potential properties for improving vascular endothelial function. Thus, we aimed to investigate the effect of TMST on endothelial dysfunction in CSFP, Endothelial-dependent flow-mediated vasodilation, serum levels of nitric oxide, adiponectin, and endothelin-1 were surveyed before and after 3 months of TMST treatment...

Oesophageal cancer (OC) is one of the most fatal malignancies in the world, and chemoresistance restricts the therapeutic outcome of OC. Long noncoding RNA (lncRNA) was reported to play roles in multiple cancer types. Yet, the function of lncRNA in chemoresistance of OC has not been reported. A lncRNA gene, PCAT-1, showed higher expression in OC tissues, especially higher in secondary OC compared with normal mucosa tissues. Overexpression of PCAT-1 increased the proliferation rate and growth of OC cells. Inhibition of PCAT-1 decreased proliferation and growth of OC cells, and increased cisplatin chemosensitivity...

The purpose of this study was to determine if Shc proteins influence the metabolic response to acute (7 days) feeding of a high-fat diet (HFD). To this end, whole animal energy expenditure (EE) and substrate oxidation were measured in the Shc knockout (ShcKO) and wild-type (WT) mice fed a control or HFD. The activities of enzymes of glycolysis, the citric acid cycle, electron transport chain (ETC), and β-oxidation were also investigated in liver and skeletal muscle of ShcKO and WT animals. The study showed that ShcKO increases (P < ...

Peroxisome proliferator-activated receptors (PPARs) play a major role in metabolism and inflammatory control. Exercise can modulate PPAR expression in skeletal muscle, adipose tissue, and macrophages. Little is known about the effects of PPAR-α in metabolic profile and cytokine secretion after acute exercise in macrophages. In this context, the aim of this study was to understand the influence of PPAR-α on exercise-mediated immune metabolic parameters in peritoneal macrophages. Mice C57BL/6 (WT) and PPAR-α knockout (KO) were examined in non-exercising control (n = 4) or 24 hours after acute moderate exercise (n = 8)...

Temporal lobe epilepsy is a chronic disorder of nerve system, mainly characterized by hippocampal sclerosis with massive neuronal loss and severe gliosis. Aberrant neurogenesis has been shown in the epileptogenesis process of temporal lobe epilepsy. However, the molecular mechanisms underlying aberrant neurogenesis remain unclear. The roles of Wnt signalling cascade have been well established in neurogenesis during multiple aspects. Here, we used kainic acid-induced rat epilepsy model to investigate whether Wnt/β-catenin signalling pathway is involved in the aberrant neurogenesis in temporal lobe epilepsy...

In hepatocytes, ursodeoxycholic acid (UDCA) activates cell signalling pathways such as p53, intracellular calcium ([Ca(2+) ]i ), and sphingosine-1-phosphate (S1P)-receptor via Gαi -coupled-receptor. Recently, UDCA has been shown to protect the heart against hypoxia-reoxygenation injury. However, it is not clear whether UDCA cardioprotection against hypoxia acts through a transcriptional mediator of cells stress, HIF-1α and p53. Therefore, in here, we aimed to investigate whether UDCA could protect cardiomyocytes (CMs) against hypoxia by regulating expression of HIF-1α, p53, [Ca(2+) ]i , and S1P-Gαi -coupled-receptor...

Cervical cancer is one of the most common cancers among women worldwide. It is highly lethal yet can be treated when found in early stage. Thus, early detection is of significant important for early diagnosis of cervical cancer. Exosomes have been used as biomarkers in clinical diagnosis. It is unknown that whether blood exosomes associated with cervical cancer can be detected and if these exosomes can accurately represent the developmental stage of cervical cancer. Mouse models were made out of a relapsed cervical cancer patient's tumour sample for original and recurrent cervical cancer, and gene analysis in both tumours and exosomes in these mouse models were performed...

High Mobility Group AT-hook 1 (HMGA1) was identified as a target of miR-214 in human cervical and colorectal cancers (CaCx and CRC) in a previous study. While the expression of miR-214 remains suppressed, HMGA1 behaves as a potent oncogene and plays crucial roles in several aberrant signalling pathways by interacting with intermediates like RELA, CTNNB1, STAT3, and TP53 in CaCx and CRC. Hypothetically, miR-214 should be able to regulate the stabilization of some of these intermediates through the regulation of HMGA1...

Reversing the function of cancer-associated fibroblasts (CAFs) may improve the efficacy of cancer therapy. Here, we isolated a novel polysaccharide from Dictyophora indusiata (ZSP4) and examined its effects on the function of prostate CAFs. The supernatant of prostate CAFs can stimulate the proliferation of immune cells and inhibit the growth of CD4+/CD8+ T cells. However, after ZSP4 stimulation, the functions of prostate CAFs were inhibited. The mechanism experiment shows that ZSP4 can stimulate prostate CAFs by down-regulating the expression of α-smooth muscle actin...

Mesenchymal stem cells (MSCs) have therapeutic potential for treatment of diabetes. However, in vitro behavior of MSCs in high glucose condition as well as presence of glucose lowering agents is not fully understood. Because MSCs have an important role in tissue repair, we examined the effects of metformin and celecoxib on viability of MSCs in different glucose conditions. MSCs, from umbilical cord blood, were cultured in normoglycemic (glucose 5.5 mM), midglycemic (glucose 10 mM), and hyperglycemic (glucose 25 mM) conditions, and the cell viability was evaluated by MTT assay...

Brain-derived neurotrophic factor (BDNF) is a neurotrophin that can promote the development and proliferation of neurons. BDNF has been found to be involved in male reproduction. Leydig cells in testicular interstitial tissues can secrete testosterone in a luteinizing hormone-dependent manner. We showed that BDNF and its receptor TrkB were expressed in mice TM3 Leydig cells in the present study. Furthermore, BDNF can promote proliferation of mouse TM3 Leydig cells in vitro. Results of microRNA (miRNA) deep sequencing showed that BDNF can alter the expression profile of miRNAs in TM3 Leydig cells...

Although oxygen concentrations affect the growth and function of mesenchymal stem cells (MSCs), the impact of hypoxia on osteoblastic differentiation is not understood. Likewise, the effect of hypoxia-induced epigenetic changes on osteoblastic differentiation of MSCs is unknown. The aim of this study was to examine the in vitro hypoxic response of human periosteum-derived cells (hPDCs). Hypoxia resulted in greater proliferation of hPDCs as compared with those cultured in normoxia. Further, hypoxic conditions yielded decreased expression of apoptosis- and senescence-associated genes by hPDCs...

Progress in the understanding of the molecular mechanism for acute myeloid leukaemia is of great significance to generate new potential targets for treatment. Recent studies showed that HOXA9, a homeodomain-containing transcription factor, is commonly deregulated in acute leukaemia. In this study, we elucidated the direct correlation between HoxA9 expression and progression of leukaemia using 2 different types of leukaemia cells HL-60 and MOLT-3. The HoxA9 expression level was decreased in leukaemia cells with the treatment of all-trans retinoic acid or arsenic trioxide (As2 O3 )...
