The chemokine receptor CXCR5 is expressed by B cells and certain T cells and controls their migration into and within lymph nodes. Its ligand BCA-1/CXCL13 is present in lymph nodes and spleen and also in the liver. Surprisingly, we detected CXCR5 in several mouse and human carcinoma cell lines. CXCR5 was particularly prominent in pancreatic carcinoma cell lines and was also detected by immunohi...

Based on the previously described roles of doxorubicin in immunogenic cell death, both doxorubicin and liposomal doxorubicin (Doxil) were evaluated for their ability to boost the antitumor response of different cancer immunotherapies including checkpoint blockers (anti-PD-L1, PD-1, and CTLA-4 mAbs) and TNF receptor agonists (OX40 and GITR ligand fusion proteins) in syngeneic mouse models. In a ...

Polyplex micelles have demonstrated biocompatibility and achieve efficient gene transfection in vivo. Here, we investigated a polyplex micelle encapsulating genes encoding the tumor-associated antigen squamous cell carcinoma antigen recognized by T cells-3 (SART3), adjuvant CD40L, and granulocyte macrophage colony-stimulating factor (GM-CSF) as a DNA vaccine platform in mouse tumor models with ...

background: adipose tissue has characteristics of an endocrine organ which releases a number of adipocyte-specific factors, known as adipocytokines.  it has recently suggested that adipocytokines might play a role in pathogenesis and progression of certain cancers, especially in gastric cancer.  this study has managed to investigate endogenous and/or exogenous expression of visfatin and resisti...

background: mehr-80 is a newly established adherent human large cell lung cancer cell line that has not been transfected until now. this study aims to define the optimal transfection conditions and effects of some critical elements for enhancing gene delivery to this cell line by utilizing different non-viral transfection procedures. methods: in the current study, calcium phosphate (cap), deae-...

many cell lines, when cultured under proper conditions, can form three dimensionalstructures called multicellular spheroids. these spheroids resemble in vivo tumor models in severalaspects. therefore, studying growth characteristics and behavior of spheroids is beneficial inunderstanding the behavior of tumors under various experimental conditions. in this work, we havestudied the growth proper...

background: bacterial dna has immunostimulatory effects on different types of immune cells such as dendritic cells (dcs). application of dcs as a cellular adjuvant represents a promising approach in the immunotherapy of infectious disease and cancers. objectives: to investigate the effect of tumor antigen pulsed dcs in the presence of cpg-1826 in treatment of a murine model of cancer. methods: ...

Herbal medicines are currently attracting much attention as a potential cancer treatment. Juglans regia’s wide variety of anticancer actions have been demonstrated. The aim this study is evaluating the cytotoxic and antioxidant effects walnut oil (J. regia) nanoemulsion (WO-NE) on CT26 colon cell line. dimensions structure were studied by dynamic light scattering (DLS) transmission electron mic...

Identification of appropriate models for in vivo and in vitro preclinical testing of inhibitors of tumor angiogenesis and progression is vital to the successful development of anticancer therapeutics. Although the focus is on human molecular targets, most preclinical in vivo efficacy testing occurs in mice. The goal of the current studies was to identify a murine endothelial cell line to model ...

Anti-HER2/neu therapy of human HER2/neu-expressing malignancies such as breast cancer has shown only partial success in clinical trials. To expand the clinical potential of this approach, we have genetically engineered an anti-HER2/neu IgG3 fusion protein containing GM-CSF. Anti-HER2/neu IgG3-(GM-CSF) expressed in myeloma cells was correctly assembled and secreted. It was able to target HER2/ne...
