We evaluated the effect of a basic fibroblast growth factor (bFGF) and saporin conjugate (bFGF-SAP) on proliferation, migration and tubule formation in bovine choriocapillary endothelial cells (BCECs). Cell proliferation and MTS assays were done with 0.01, 0.1, 1, 10, and 100 nM bFGF-SAP, and an equimolar concentration of bFGF and saporin. TUNEL assay was performed to confirm apoptosis. Cells w...

Background: Cystic echinococcosis (CE), also known as echinococcosis/hydatidosis, is one of the most important parasitic diseases in the world. It enhances both humoral and cellular (Th1 and Th2) responses in infected host. Different antigens of the worm may favor the Th1 or Th2 immune responses in CE patients. Objective: To evaluate the humoral and cellular immune responses of Balb/c mice agai...

primula auriculata (tootia) is one of the most important local medicinal plants in hamedan district, iran. to investigate cytotoxicity and apoptosis induction of crude methanolic extract and different fraction of it we compared several methods on ht-29 human colon adenocarcinoma cells. cancer cell proliferation was measured by 3-(4, 5‑dimethylthiazolyl)-2, 5‑diphenyl‑tetrazolium bromide (mtt) a...

objective(s):degradation of sphingosine 1-phosphate (s1p), as a bioactive lipid, or deregulation of its production involves in tumor progression, metastasis and chemoresistance. since the tumor progression effects of s1p and its mechanism in chronic lymphoblastic leukemia and non-small cell lung cancer is not fully understood, we investigated the role and one of the mechanisms of s1p in tumor p...

in many acute leukemias, normal differentiation does not occur. however, in many cell lines derived from hematologic malignancies, differentiation or programmed cell death (apoptosis) can be induced by variety of agents including: vitamin analogs, demethylating agents, cyclic amp analogs and anti-proliferative agents. to the best of our knowledge there has been not any study specifically to ana...

Impaired wound healing is among the serious complications of diabetes that can lead to amputation and even death. Plantago major has been used empirically improve healing. The main bioactive compounds P. extracts, ursolic acid (UA) oleanolic (OA), have also studied for their benefits with non-hyperglycemic wounds. This study was done examine in vivo effects leaf extracts (PMLE), UA, OA hypergly...

Thyroid cancer (TC) is the most prevalent malignant tumor in endocrine system. Serpin peptidase inhibitor clade E member 2 (SERPINE2) closely associated with metastasis. The aim of present study was to investigate whether SERPINE2 forms a feedback loop epidermal growth factor (EGF)/EGF receptor (EGFR) that regulates cellular processes human papillary thyroid carcinoma (TPC‑1) cells. Reverse tra...

Background: Norepinephrine plays a trophic role in the control of cell replication and differentiation in target cells that express adrenergic receptors. Methods: In this study, we have tested the influence of infraphysiological, physiological and supraphysiological concentrations (0.0001 nM, 1 nM, 10000 nM) of human norepinephrine on the proliferation of breast cancer cells (human breast adeno...

Piper sarmentosum or ‘kaduk’ is a well-known herb plant in Malaysia. Its extracts were found to exhibit bone-protective effect against osteoporotic rats. Our study aim morphologically observe the of P. ethyl acetate extract on differentiation human peripheral blood stem cells (PBSCs) into osteoblasts. (1-900 µg/mL) prepared using 1% dimethyl sulfoxide (DMSO) used cytotoxicity assay. Then, assay...
