1. TNF-alpha increases angiogenic potential in a co-culture system of dental pulp cells and endothelial cells
Abstract We recently demonstrated that a co-culture system of human umbilical vein endothelial cells (HUVECs) and human dental pulp stem cells (hDPSCs) could enhance angiogenesis ability in vitro. However, whether tumor necrosis factor α (TNF-α) could promote blood vessel formation during pulp regeneration remained unknown. The aim of this study was to inv

2. Benzyl isothiocyanate inhibits invasion and induces apoptosis via reducing S100A4 expression and increases PUMA expression in oral squamous cell carcinoma cells
Benzyl isothiocyanate (BITC) has been shown to inhibit invasion and induce apoptosis of various types of cancer. However, its role on human oral squamous cell carcinoma (OSCC) cells is still not well elucidated. In the present study, we investigated the effect of BITC on apoptosis and invasion of SCC9 cells, and its underlying mechanisms in vitro and in vivo

3. Primary tumorectomy promotes angiogenesis and pulmonary metastasis in osteosarcoma-bearing nude mice
PURPOSE: To investigate the effect of primary tumorectomy on angiogenesis and pulmonary metastasis in osteosarcoma-bearing nude mice. METHODS: Osteosarcoma was introduced to nude mice via subcutaneous injection of MG-63 cells. One hundred and eighty osteosarcoma-bearing mice were used equally in 3 parallel experiments. The effect of tumorectomy (TR) on the e

4. RNAi-mediated knockdown of pituitary tumor- transforming gene-1 (PTTG1) suppresses the proliferation and invasive potential of PC3 human prostate cancer cells
Pituitary tumor-transforming gene-1 (PTTG1) is a proto-oncogene that promotes tumorigenesis and metastasis in numerous cell types and is overexpressed in a variety of human tumors. We have demonstrated that PTTG1 expression was up-regulated in both human prostate cancer specimens and prostate cancer cell lines. For a more direct assessment of the function of

5. M2-polarized macrophages promote metastatic behavior of Lewis lung carcinoma cells by inducing vascular endothelial growth factor-C expression
OBJECTIVES: Tumor-associated macrophages that generally exhibit an alternatively activated (M2) phenotype have been linked to tumor progression and metastasis. However, the role of M2-polarized macrophages in the growth and metastasis of lung adenocarcinoma remains enigmatic. The aim of this study was to explore the effect of M2 macrophages on the proliferat

6. Isolamento e caracterização de células progenitoras endoteliais de medula óssea de camundongos para utilização em terapia celular / Isolation and characterization of endothelial progenitor cells derived from bone marrow of mice for use in cell therapy
As células progenitoras endoteliais (CPEs) foram descritas por Asahara et al. (1997), isoladas a partir do sangue periférico e são células originadas da medula óssea. Estas células podem ser reconhecidas pela expressão de marcadores como o CD34, CD133, VEGFR2 e o CD31, pela capacidade de internalização de acLDL e de formar estruturas semelhantes a v

7. Investigação dos mecanismos de ação do Amblyomin-X sobre a angiogênese in vivo induzida pelo VEGF / Investigation of mechanisms of action of Amblyomin-X on in vivo on VEGF-induced angiogenesis
Amblyomin-X é um inibidor de serinoprotease do tipo kunitz obtido de uma biblioteca de cDNA das glândulas salivares do carrapato Amblyomma cajannense. Dados preliminares mostraram que a injeção in vivo de Amblyomin-X reduziu a formação de massa tumoral induzida por células de melanoma B16F10 em camundongos. Com base neste dado e na ação de inibidore

8. Ação do inibidor de calicreína em linhagens de câncer de próstata / Action of kallikrein inhibitor on prostate cancer cell lines
Prostate cancer is the second more frequent type of cancer. In this work, using DU145 and PC3 prostate cancer cellular lines, we studied the effect of recombinant kallikrein inhibitor modified form (rBbKm), in which the sequence containing the signal motif sequence RGD of the inhibitor BrTI from Bauhnina rufa was inserted. When DU145 and PC3 were incubated w

9. Modelos para a produção de eritropoietina recombinante humana in vivo e in vitro com vetores plasmideais em ovinos / Models for the production of human recombinant erythropoietin in vivo and in vitro with plasmidial vectors in ovine
Some post-translational modifications are necessary for the production of biopharmaceutical proteins, such as recombinant human erythropoietin (rhEPO), with a good specific action and a high biological activity. These modifications are obtained only by bioreactors based on eukaryotic cell as mammary cells. Bioreactors, in vivo or in vitro, with this kind of

10. Efeito de cistatinas recombinantes de cana-de-açúcar na angiogênese e desenvolvimento tumoral
Células tumorais expressam um grande numero de proteases que têm importante função no desenvolvimento tumoral e metástases. Algumas destas proteases podem atuar também na regulação da angiogênese. Catepsinas são proteases lisossomais que estão expressas em células tumorais, podendo translocar-se para a superfície da célula e serem secretadas. I

Galactanas e o termo utilizado para designar polissacarideos que contem galactose. Homogalactanas sulfatadas, SG 1 e SG 2, foram extraidas de macroalga marinha verde Codium isthmocladum apos proteolise, fracionamento por acetona a frio e cromatografia de troca-ionica. A massa molecular foi determinada por cromatografia de gel-filtracao em HPLC e deteccao por

12. Vimentin expression and the influence of Matrigel in cell lines of head and neck squamous cell carcinoma
Vimentin is a cytoeskeletal intermediate filament protein commonly observed in mesenchymal cells; however, it can also be found in malignant epithelial cells. It is demonstrated in several carcinomas, such as those of the cervix, breast and bladder, in which it is widely used as a marker of the epithelial to mesenchymal transition that takes place during emb
