Vero cell heparin-binding epidermal growth factor-like growth factor (HB-EGF) is synthesized as a 20- to 30-kDa membrane-anchored HB-EGF precursor (proHB-EGF). Localization and processing of proHB-EGF, both constitutive and 12-O-tetradecanoylphorbol 13-acetate (TPA)-inducible, was examined in Vero cells overexpressing recombinant HB-EGF (Vero H cells). Flow cytometry and fluorescence immunostai...

Purpose: To investigate the effect of the aqueous extract of Zingiber officinale Roscoe. (ZOA) rhizome on the activity and expression of matrix metalloproteinase (MMP)-2, MMP-9, tissue inhibitor of metalloproteinase (TIMP)-1 and TIMP-2 using an in vitro model of Dengue virus (DV) infection. Methods: Z. officinale rhizomes were extracted with water by continuous shaking for 5 days. The total phe...

Respiratory syncytial (RS) virus infects the epithelium of the respiratory tract. We examined the replication and maturation of RS virus in two polarized epithelial cell lines, Vero C1008 and MDCK. Electron microscopy of RS virus-infected Vero C1008 cells revealed the presence of pleomorphic viral particles budding exclusively from the apical surface, often in clusters. The predominant type of ...

In vitro antiviral activities of three flavonoids; fisetin, naringenin and rutin against DENV-2 (NGC strain) were evaluated. Inhibitory effects of each compound at the different stages of DENV-2 infection were examined using foci forming unit reduction assay (FFURA) and quantitative real-time polymerase chain amplification (qRT-PCR). Fisetin, rutin and naringenin showed cytotoxic effects agains...

Renal disorders have become very common nowadays, which may also lead to kidney failure. The disorder may be caused by the commonly used chemicals such as acetaminophen, CCl4, streptromycin, H2O2 etc. The objective of this work is to determine the nephroprotective potential of ethanolic extract against H2O2 induced toxicity in VERO cell line. Ethanolic extract is known for its antioxidant, anti...

Mutational inactivation of p53 is a key player in the development of human cancer. Thus, retrieving the tumor suppressor activity of p53 gene is considered a novel strategy in cancer therapy. Current study aimed to investigate the anti-cancer potentials of botulinum toxin type-A (BTX-A) and captopril as a trial to shed light on effective anti-cancer therapy with lower side effects. Cytotoxic ef...

Respiratory syncytial virus (RSV) is the most common cause of bronchiolitis in infants and young children. A small percentage of these individuals develop severe and even fatal disease. To better understand the pathogenesis of severe disease and develop therapies unique to the less-developed infant immune system, a model of infant disease is needed. The neonatal lamb pulmonary development and p...

During one year study, 394 stool samples obtained from a random cases of diarrhea were examined for the presence of free shiga-like toxins Stx1 and Stx2 in Vero cells assay. Of 394 stool specimen supernatants tested, 2 (0.5%) gave positive results. The two stool supernatants positive on Vero cell line were wholly capable of being neutralized with the monoclonal antibody to Stx2. Broth cultures ...
