it is well known that several plant extracts have a lactogenic effect. this response may be inducedthrough the stimulation of prolactin release from lactotrope cells. a partial purification of the activecompound indicated that it is rich in pectin and β-glucan. these materials stimulate secretion of prolactinfrom hypophyseal fragments. in the present study, the effect of β-glucan on the secreti...

 Background: Non-melanoma skin cancer is the most common malignant tumor in humans. The role of ultraviolet radiation is well-known in the pathogenesis of basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). CD10 is a zinc-dependent metallopeptidase known as common acute lymphoblastic leukemia antigen (CALLA). Although CD10 expression has been investigated in some cutaneous tu...

the adhesive interaction between tumor cells and the host cells or the extracellular matrix plays a crucial role in tumor metastasis. to evaluate the mediation of cell adhesion by daphne mucronata, an anti-cancer medicinal plant in iranian folk medicine, the adhesion of thrombin activated human platelets to the cultured monocytes or hl-60 cells was investigated under the effect of the plant ext...

within a single tumor clone, cells have significantly different abilities to proliferate and form new tumors. this has led to the hypothesis that most cells in a cancer have a limited ability to divide and only a small subset of distinct cells, the cancer stem cells (cscs), has the capacity to self-renew and form new tumors . it has been proposed that the development of tumors is based exclusiv...

Background & Objective: Recent studies from gene profiling have revealed some genes that are overexpressed in the epithelial-mesenchymal transition (EMT) process and are responsible for its initiation and activation resulting in tumor progression and metastasis. The present study aimed to assess the role of genes involved in the EMT process and the association of these genes wi...

background: the ectopic expression of receptor tyrosine kinase ror1 has been reported in patients with hematological malignancies such as chronic lymphocytic leukemia and acute lymphoblastic leukemia. here we report, for the first time, expression of ror1 gene in both tumor tissues and peripheral blood mononuclear cells (pbmc) from patients with renal cancer (rc). methods: in the current study,...

Objectives: The study of core-shell magnetic nanoparticles has a wide range of applications because of the unique combination of the nanoscale magnetic core and the functional shell. Characterization and application of one important class of core-shell magnetic nanoparticles (MNPs), i.e., iron oxide core (Fe3O4/γ-Fe2O3) with a silica shell and outer of gold (Fe3O4-SiO2@Gold (FSG)) in Boron Neut...

granulocytic sarcoma (gs) is an unusual extramedullary tumor composed of immature granulocytic precursor cells. the intraoral occurrence of this tumor is extremely rare. here we report a case of gs with palatal swelling, gingival lesions in maxilla and mandible and aleukemic presentation in a 45 years old man.

Objective(s): The stress-responsive genes of Sestrin family are recognized as new tumor suppressor genes in breast carcinoma, however, the function of Sestrin family in human prostate cancer is not clear. Ionizing radiation (IR) is known to induce Sestrin gene expression in breast cancer cells. However, the response of Sestrin to IR has not been reported in PC3 prostate cancer cells. Materials ...
