Neuroprotective mechanism of low-dose sodium nitrite in oxygen-glucose deprivation model of cerebral ischemic stroke in PC12 cells Anzeigen

The purpose of this study was to clarify the mechanisms of the protective effects of low-dose sodium nitrite (SN) on oxygen and glucose deprivation (OGD)-induced endoplasmic reticulum (ER) stress in PC12 cells. The PC12 cells were exposed to 4 h of OGD and treated with 100 μmol SN. The expression and activity of ER stress markers, including PKR-like endoplasmic reticulum kinase (PERK), transcription factor 6 (ATF6), CCAAT/enhancer binding protein homologous protein (CHOP), as well as caspase-...

Design and synthesis of photoactivatable myristic acid analogues for UNC119 cargo interactions and target identification of autophagy inhibitors Anzeigen

UNC119 is a chaperone protein, which regulates the trafficking of myristoylated proteins between cellular membranes. Even though these chaperones were extensively studied in the past two decades, only few of their interaction partners are known to date. In the course of this thesis three different photoactivatable myristic acid analogues (Pacman 1-3) were designed and synthesized to study this protein-myristate interaction. Exclusively Pacman-3-based probes covalently labeled UNC119 proteins....

Spatial unification of coupling interactions between EGFR and PTPs establishes a growth factor sensing network Anzeigen

Cells continuously sense and respond to stimuli from the non-stationary environment. For this, they optimise processing of the perceived signals while maintaining continuous responsiveness. Cell surface receptors, such as the receptor tyrosine kinases, comprise the first layer of sensing. They translate the extracellular signal into internal activity using the protein interaction networks in which they are embedded. The proto-oncogenic epidermal growth factor receptor (EGFR) is a receptor ty...

Rational design of novel sirtuin 1 activators via structure-activity insights from application of QSAR modeling Anzeigen

Sirtuin 1 (SIRT1) enzyme regulates major cell activities, and its activation offers lucrative therapeutic potentials for aging diseases including Alzheimer’s disease (AD). Regarding the global aging society, continual attention has been given to various chemical scaffolds as a source for the discovery of novel SIRT1 activators since the discovery of the pioneer activator, resveratrol. Understanding structure-activity relationship (SAR) is essential for screening, designing as well as impr...

The effect of heat shock protein 90 inhibitors on histone 4 lysine 20 methylation in bladder cancer Anzeigen

Heat shock protein 90 (HSP90), an ATP-dependent molecular chaperone required for the stability and function of numerous oncogenic signaling, is one of the hallmarks of cancer. Recent years, the studies showed that HSP90 plays a pivotal role in epigenetic pathways. Epigenetic regulation plays an important role in the etiology of bladder cancer. The aim of the present study was to investigate the effect of HSP90 proteins on DNA methylation and the levels of inactivated histone methylation m...

MCT4 promotes cell proliferation and invasion of castration-resistant prostate cancer PC-3 cell line Anzeigen

Prostate cancer (PCa) is one of the leading causes of cancer-related death in men. Blocking androgen receptor (AR) signaling is an effective treatment strategy for the treatment of advanced metastatic disease of PCa in men. However, the method of blocking AR signaling is not suitable for castration-resistant prostate cancer (CRPC), and the treatment of CRPC is still clinically difficult. It has recently been reported that MCT4 is a plasma membrane transporter that mediates the secretion o...

Cytotoxicity and apoptogenic properties of the standardized extract of Portulaca oleracea on glioblastoma multiforme cancer cell line (U-87) Anzeigen

The traditional uses of Portulaca oleracea L. (PO) with anti-inflammatory and anti-cancer activity as well as antioxidants properties were expressed previously. Glioma is considered the most common primary brain tumor and its malignant form is the most lethal adult brain tumor, that glioblastoma covers about 50 % of glioma tumors. The present study was aimed to evaluate the cytotoxicity and apoptogenic effects of the hydro-ethanolic extract of PO on human glioblastoma cancer cell line (U-...

Induction of apoptosis by piperine in human cervical adenocarcinoma via ROS mediated mitochondrial pathway and caspase-3 activation Anzeigen

Piperine (1-piperoylpeperdine), a nitrogenous pungent substance, is present in the fruits of black pepper (Piper nigrum Linn.) and long pepper (Piper longum Linn.). It possesses several pharmacological properties and has been extensively explored for its anti-cancerous activities. The mechanism underlying its anti-cancer potential in human cervical adenocarcinoma (HeLa) cells is not well interpreted. The anti-proliferative effect and the mode of action of piperine were investigated through so...

Effect of cerebral dopamine neurotrophic factor on endogenous neural progenitor cell migration in a rat model of Parkinson's disease Anzeigen

This study investigated the ability of intra-subventricular zone (SVZ) administration of cerebral dopamine neurotrophic factor (CDNF) on neural progenitor cells (NPCs) attraction from the SVZ toward the 6-hydroxydopamine (6-OHDA)-lesioned striatum and improvement of motor dysfunctions in Parkinsonian rats. Male Wistar rats were assigned to four groups of the sham model (Sham), 6-OHDA-lesioned (OH), 6-OHDA-lesioned plus CDNF vehicle (OH+Vehicle), and 6-OHDA-lesioned plus CDNF (OH+CDNF). The an...

Therapeutic effect of Baccharis anomala DC. extracts on activated hepatic stellate cells Anzeigen

The therapeutic potential of Baccharis anomala DC. extracts was evaluated through its cytotoxic and antiproliferative effect and their phenotypic reversion property in activated hepatic stellate cells (HSCs). Baccharis anomala is distributed in Brazil (southeastern and south regions) and used for diuretic effect in folk medicine. Four fractions were obtained from the fractionation of the methanolic extract. Fractions III and IV decreased cell proliferation without increasing cell necrosis mar...

Prostate cancer metastasis and soy isoflavones Anzeigen

Prostate cancer is a complex, progressive, bone-tropic disease, which is usually associated with skeletal issues, poor mobility and a fatal outcome when it reaches the metastatic phase. Soy isoflavones, steroid-like compounds from soy-based food/dietary supplements, have been found to decrease the risk of prostate cancer in frequent consumers. Herein, we present a systematization of the data on soy isoflavone effects at different stages of metastatic prostate cancer progression, with a parti...

Molecular diagnosis of glycogen storage disease type I Anzeigen

Glycogen storage disease type I (GSD I) is a relatively rare metabolic disease with variable clinical intensity. It is caused by deficient activity of the glucose 6-phosphatase enzyme (GSD Ia) or a deficiency in the microsomal transport proteins for glucose 6-phosphate (GSD Ib). We searched the most recent English literature (1997-2017) regarding any article with the key word of “glycogen storage disease type I” in PubMed, Science Direct, Scopus, EMBASE, and Google Scholar. We will present al...

Association of biofilm formation and cytotoxic potential with multidrug resistance in clinical isolates of Pseudomonas aeruginosa Anzeigen

Multidrug resistant (MDR) Pseudomonas aeruginosa having strong biofilm potential and virulence factors are a serious threat for hospitalized patients having compromised immunity. In this study, 34 P. aeruginosa isolates of human origin (17 MDR and 17 non-MDR clinical isolates) were checked for biofilm formation potential in enriched and minimal media. The biofilms were detected using crystal violet method and a modified software package of the automated VideoScan screening method. Cytotox...
