Chaharmahal and Bakhtiari province is a most important endemism states of flora of Iran with a considerable plant species diversity in the country. In the present study the cytotoxic activity of 13 plant species grown in Chaharmahal and Bakhtiari have been evaluated on prostate (PC-3), breast (MCF-7), liver (HepG2), ovary (CHO) and melanoma (B16-F10) cancer cell lines. The cytotoxicity and apop...

Caveolin-1 is known to promote cell migration, and increased caveolin-1 expression is associated with tumor progression and metastasis. In fibroblasts, caveolin-1 polarization and phosphorylation of tyrosine-14 are essential to promote migration. However, the role of caveolin-1 in migration of metastatic cells remains poorly defined. Here, caveolin-1 participation in metastatic cell migration w...

The tumor microenvironment (TME) fosters tumors by attenuating anti-tumor immunity, reinforcing tumor cell survival and increasing angiogenesis. Among the constituents of the TME, here, we focused on tumor-associated neutrophils (TANs). First, we found that the combination of poly I:C and inactivated Sendai virus particles (hemagglutinating virus of Japan envelope; HVJ-E) synergistically suppre...

The suitability of liposomes as drug carriers in the treatment of drug-resistant rodent malaria was examined after covalently attaching F(ab')2 fragments of a mouse monoclonal antibody (MAb), MAb F10, raised against the host cell membranes isolated from the Plasmodium berghei-infected mouse erythrocytes, to the liposome surface. The antibody-bearing liposomes thus formed specifically recognized...

Inhibition of neuronal nicotinic receptors can be regulated by the presence of specific amino acids in the beta subunit second transmembrane domain (TM2) domain. We show that the incorporation of a mutant beta4 subunit, which contains sequence from the muscle beta subunit at the TM2 6' and 10' positions of the neuronal beta4 subunit, greatly reduces the sensitivity of receptors to the local ane...

BACKGROUND Angiogenesis plays an important role in tumor growth, invasion, and eventually metastasis. Antiangiogenic strategies have been proven to be a promising approach for clinical therapy for a variety of tumors. As a potent inhibitor of tumor angiogenesis, pigment epithelium-derived factor (PEDF) has recently been studied and used as an anticancer agent in several tumor models. METHODS ...

Chronic kidney disease (CKD) is recognized as a risk factor not only for end-stage renal disease but also for cardiovascular disease. Early detection and treatment of CKD is a likely key factor for prevention of its complications. Although genetic linkage analyses and association studies have implicated several loci and candidate genes in predisposition to CKD, the genes that underlie genetic s...

In established tumors, angiogenic endothelial cells (ECs) coexist next to "quiescent" EC in matured vessels. We hypothesized that angio-gene expression of B16.F10 melanoma would differ depending on the growth stage. Unraveling the spatiotemporal nature thereof is essential for drug regimen design aimed to affect multiple neovascularization stages. We determined the angiogenic phenotype-represen...
