Objective: To Research of hiperfect-mediated RNA interference targeting human telomerase reverse transcriptase gene (hTERT) on the biological behavior malignant melanoma cell line A375.Methods: Specific siRNAs with green fluorescent labeling different concentrations were transfected into A375 cells by using transfection reagent (Hiperfect) at volumes . The efficiency was determined fluorescen m...
زمینه و هدف: سلول های بنیادی سرطان در تهاجم و متاستاز ملانوما، کشنده ترین و تهاجمی ترین شکل سرطان پوست، دخیل می باشند. در پژوهش حاضر بیان شاخص های کاندید بنیادینگی cd133 و aldh1 در رده های سلولی ملانوما ارزیابی و سپس جداسازی این سلول ها بر اساس بیان این شاخص ها بررسی شد. روش کار: در این مطالعه بیان شاخص های aldh1 و cd133 در رده های سلولی a375 و d10 با استفاده از روش فلوسایتومتری ارزیابی شد. سپ...
Objective(s): The purpose of this study was to evaluate variations in yields, volatile composition and biological activities of essential oils (EOs) obtained from the aerial parts of Zhumeria majdae collected from five localities of the south of Iran. Materials and Methods: The EOs were analyzed using gas chromatography and gas chromatography-mass spectrometry techniques. The antioxidant activi...
Melanoma is the most serious type of skin disease and a leading cause of death from skin disease due to its highly metastatic ability. To develop more effective chemopreventive agents for the prevention of melanoma, we have determined the effect of green tea catechins on the invasive potential of human melanoma cells and the molecular mechanisms underlying these effects using A375 (BRAF-mutated...
BACKGROUND Our understanding of the molecular pathways that underlie melanoma remains incomplete. Although several published microarray studies of clinical melanomas have provided valuable information, we found only limited concordance between these studies. Therefore, we took an in vitro functional genomics approach to understand melanoma molecular pathways. METHODOLOGY/PRINCIPAL FINDINGS Af...
MicroRNAs (miRs) are a class of small noncoding RNAs that negatively regulate the gene expression by directly binding to the 3' untranslated region of their target mRNA, thus resulting in mRNA degradation or translational repression. miR-9 has recently been demonstrated to play a role in the development and progression of malignant melanoma (MM), but the regulatory mechanism of miR-9 in the mal...
Tissue factor (TF), the membrane glycoprotein that initiates blood coagulation, is constitutively expressed by many tumor cells and is implicated in peri-tumor fibrin deposition and hypercoagulability in cancer. Upregulation of tumor TF correlates with enhanced metastatic potential. Furthermore, TF has been colocalized with VEGF in breast cancer, specially at sites of early angiogenesis. There ...
Di-peptides derived from the human host defense peptide lactoferricin were previously described to specifically interact with the negatively charged lipid phosphatidylserine exposed by cancer cells. In this study one further derivative, namely R-DIM-P-LF11-334 is shown to exhibit even increased cancer toxicity in vitro and in vivo while non-neoplastic cells are not harmed. In liposomal model sy...
Increasing evidence has demonstrated that cell adhesion molecule 1/tumor suppressor in lung cancer 1 (CADM1/TSLC1) is crucially implicated in various biological processes, including proliferation, apoptosis, and invasion during tumorigenesis and development. However, the mechanism underlying its suppression of tumor growth and metastasis in melanoma remains elusive. The aim of the present study...
