1. Behavior of the P1.HTR mastocytoma cell line implanted in the chorioallantoic membrane of chick embryos
The P1.HTR cell line includes highly transfectable cells derived from P815 mastocytoma cells originating from mouse breast tissue. Despite its widespread use in immunogenic studies, no data are available about the behavior of P1.HTR cells in the chick embryo chorioallantoic membrane model. The objective of the present investigation was to study the effects o

2. Evaluation of the in vitro and in vivo anticancer properties of Moroccan propolis extracts
This investigation aimed to evaluate the in vitro and in vivo antitumor potential of a Moroccan propolis extracts. For in vitro assays, three mammalian tumor cell lines were used: BSR (hamster renal adenocarcinoma), Hep-2 (human laryngeal carcinoma) and P815 (murin mastocytoma). The propolis ethanolic extract as well as the ethyl acetate extract, exert an in

3. Compared cytogenetic analysis in mast cell tumors: a special focus on Boxer breed / Análise citogenética comparada em mastocitomas: enfoque especial na raça Boxer
Atualmente muitas são as técnicas utilizadas na área de citogenética para que os desequilíbrios genéticos potencialmente hereditários sejam identificados ou evitados. Algumas das técnicas são utilizadas apenas para o diagnóstico de enfermidades em humanos, mas seria importante que fossem aplicadas também aos animais domésticos, com a finalidade d

4. Concordância entre observadores e importância prognóstica das variáveis de Patnaik, Ehler &MacEwen e da análise sintática estrutural de mastocitoma cutâneo canino / Agreement between observers and prognostic relevance of variables from Patnaik, Ehler &MacEwen and syntactic structure analysis of cutaneous canine mast cell tumor
O sistema de graduação histológica desenvolvido por Patnaik et al. (1984), provou ser de relevância prognóstica nos Mastocitomas Cutâneos Caninos (MCC). Os parâmetros subjetivos utilizados em sua graduação têm levado patologistas veterinários a conferir diferentes graus a uma mesma amostra. Este fato pode refletir negativamente no estabelecimento

5. Cytotoxic effect of essential oil of thyme (Thymus broussonettii) on the IGR-OV1 tumor cells resistant to chemotherapy
The anti-tumor effect of the Moroccan endemic thyme (Thymus broussonettii) essential oil (EOT) was investigated in vitro using the human ovarian adenocarcinoma IGR-OV1 parental cell line OV1/P and its chemoresistant counterparts OV1/adriamycin (OV1/ADR), OV1/vincristine (OV1/VCR), and OV1/cisplatin (OV1/CDDP). All of these cell lines elicited various degrees

6. Indicadores prognósticos para mastocitomas: estudo morfométrico e imunoistoquímico / Prognostic indicators for mast cell tumors: a morphometric and immunohistochemical study
Ninety-three canine cutaneous mast cell tumors, of 74 dogs, had their clinical history investigated. Among these, 25 cases were submitted to nuclear morphometric analysis on cytopathology slides stained by panoptic method and hematoxylin &eosin; and 28 cases were submitted to histopathologic grading and immunohistochemistry to evaluate KIT, BAX, Ki-67 e PCNA

7. Dog mastocytoma cells produce transforming growth factor beta 1.
Transforming growth factor-beta (TGF beta) promotes deposition of extracellular matrix and is associated with fibrotic conditions both in experimental animals and in humans. Although a role for mast cells has been suspected in the pathogenesis of fibrosis, no potent mediator capable of stimulating fibroblast growth or extracellular matrix deposition has been

8. Synthesis and activation of mitotic Ca2+-adenosinetriphosphatase during the cell cycle of mouse mastocytoma cells.
The activity of a Ca2+-adenosinetriphosphatase (ATP phosphohydrolase, EC 3.6.1.3) increases during the mitotic phase of synchronized mouse mastocytoma P-815X2 cells. The enzyme is synchronized mouse mastocytoma P-815X2 cells. The enzyme is synthesized mainly during a distinct period of the interphase and is activated at mitosis. It is thought to regulate the

9. Determination of immune complexes in sera from dogs with various diseases by mastocytoma cell assay.
Canine immunoglobulin G complexed with particulate or soluble antigen can bind to the Fc receptors on the mastocytoma cells. Attachment of immune complexes composed of immunoglobulin G and soluble antigen (ovalbumin) to mastocytoma cells was detected by an inhibition of rosette formation with indicator cells (sensitized sheep erythrocytes). Therefore, canine

10. Dog mastocytoma cells secrete a 92-kD gelatinase activated extracellularly by mast cell chymase.
Gelatinolytic metalloproteinases implicated in connective tissue remodeling and tumor invasion are secreted from several types of cells in the form of inactive zymogens. In this report, characterization of gelatinase activity secreted by the BR line of dog mastocytoma cells reveals a phorbol-inducible, approximately 92-kD, Ca2+ - and Zn2+ -dependent proenzym

11. Mastocytoma in a cow: a case report.
Mastocytoma was diagnosed in a four year old Holstein cow. The enlarging mass was clinically determined to be metastatic to the right superficial cervical lymph node. Cytological examination of both sites revealed mast cell neoplasia. Histopathological examination confirmed the presence of this tumor in these same sites as well as in liver, kidney and adrena
