OBJECTIVE Micromolar concentrations of the proangiogenic metabolite deoxyribose-1-phosphate (dRP) were detected in platelet supernatants by mass spectrometry. In this study, we assessed whether the release of dRP by platelets stimulates endothelial cell migration and angiogenesis. METHODS AND RESULTS Protein-free supernatants from thrombin-stimulated platelets increased human umbilical vein e...
background :wide distribution and low half-life of acyclovir has led to a high dose consumption of the drug. recent studies have shown that encapsulation of acyclovir in nano-carriers can increase effectiveness and decrease its side effects. we investigated the inhibitory effect of acyclovir loaded nano-niosomes against herpes simplex virus type-1 (hsv-1) in cell culture. methods : in-vitro c...
Coupling of Mitochondrial Import and Export Translocases by Receptor-Mediated Supercomplex Formation
The mitochondrial outer membrane harbors two protein translocases that are essential for cell viability: the translocase of the outer mitochondrial membrane (TOM) and the sorting and assembly machinery (SAM). The precursors of β-barrel proteins use both translocases-TOM for import to the intermembrane space and SAM for export into the outer membrane. It is unknown if the translocases cooperate ...
transforming growth factor β2 up-regulates gm-csf gene in human bladder carcinoma cell line htb 5637
transforming growth factor betas are multifunctional polypeptides in the cytokine superfamily. they have a growth inhibitory role on hemopoietic progenitor cells in semisolid colony assay as well as in long-term bone-marrow culture. tgf - β2 represses stromal cells, stem cell factor gene transcription, and decreases the stability of c-kit transcripts in hemopoietic cells. tgf-β also modulates g...
MicroRNAs (miRs) have emerged as key epigenetic regulators involved in cancer progression. miR-320a has been demonstrated to be a novel tumor suppressive microRNA in several types of cancers. In the present study, the role of miR-320a in human hepatocellular carcinoma (HCC) was investigated. The expression levels of miR-320a and messenger RNA were determined by reverse transcription-quantitativ...
Effects of fibromodulin protein expression on NFkB and TGFβ signaling pathways in liver cancer cells
Introduction: The incidence rate of liver cancer is continuously increasing. Currently, gene therapy is applied to improve various medical issues such as cancer treatment approaches. Correspondingly, fibromodulin involves in many biological and physiological processes through interaction with growth factors and signaling pathway receptors. The aim of this study was to investigate the effects of...
Abstract Background The problems associated with the poor water solubility of anticancer drugs are one most important challenges in achieving effective cancer therapy. present study was designed to evaluate effect scutellarein on human colon cells vitro by using a target α v β3 novel (Scu)-loaded niosome nanoparticle (β-CD-CL-Scu-cRGD). Results β-CD-CL-Scu-cRGD has diameter 140.2 nm and zeta po...
The ability of Bacillus subtilis, strain ALICA to produce three mycolytic enzymes (chitinase, β-1,3-glucanase, and protease), was carried out by the chemical standard methods. Bacillus subtilis ALICA was screened based on their antifungal activity in dual plate assay and cell-free culture filtrate (25%) against five different phytopathogenic fungi Alternaria alternata, Macrophomina sp., Colleto...
Objective(s): Impairment of nerve cells of brain induced by hypoxia results in energy-deprivation and dysfunction, which accompanies with neurons apoptosis. Improving function of nerve cells is important for treating cerebral anoxia. This study aimed to investigate the role of Quercetin (Quer) in hypoxia-induced injury of pheochromocytoma (PC-12) cells. Materials and Methods: PC-12 cells were c...
TRANSFORMING GROWTH FACTOR β2 UP-REGULATES GM-CSF GENE IN HUMAN BLADDER CARCINOMA CELL LINE HTB 5637
Transforming growth factor betas are multifunctional polypeptides in the cytokine superfamily. They have a growth inhibitory role on hemopoietic progenitor cells in semisolid colony assay as well as in long-term bone-marrow culture. TGF - β2 represses stromal cells, stem cell factor gene transcription, and decreases the stability of c-kit transcripts in hemopoietic cells. TGF-β also modulat...
