Padrão histológico, perfil imunoistoquímico e potencial pré-maligno das lesões diaplásicas da próstata canina /

Di Santis, Giovana Wingeter. January 2007 (has links)
Resumo: A neoplasia intra-epitelial prostática (HGPIN) e a atrofia inflamatória proliferativa (PIA) são lesões potencialmente pré-malignas encontradas na próstata humana (De Marzo et aI., 1999; Bostwick e Qian, 2004). HGPIN tem sido relatada na próstata canina com características semelhantes às observadas em humanos (Waters et aI., 1997), porém a PIA ainda não foi caracterizada nesta espécie. O presente trabalho objetivou a avaliação imunoistoquímica do índice proliferativo (PCNA e Ki67), da expressão de proteínas pró-apoptose (caspase-3), genes supressores de tumores (p-53), genes inibidores de apoptose (bcl-2) e de moléculas de adesão (E-caderina), além da avaliação histoquímica do estado proliferativo (AgNOR) e da determinação de mensurações nucleares por análise quantitativa computadorizada de imagens (AQCI) em focos HGPIN, PIA e em ácinos normais da próstata canina. Considerando os resultados de ácinos normais, constatou-se que as lesões estudadas apresentam alto índice proliferativo; capacidade proliferativa no compartimento epitelial secretor; ausência de expressão de p-53; perda de expressão de E-caderina; padrão de AgNOR semelhante ao de ácinos normais; e núcleos celulares maiores e com fator de circunferência maior. Focos de PIA exibem ainda índice apoptótico semelhante ao de ácinos normais e predomínio do linfócitos T, quando considerado o infiltrado Iinfocítico. Tais achados aproximam estas duas lesões entre si e sugerem que possam estar envolvidas no processo de transformação neoplásica da próstata canina. / Abstract: Prostatic intraepithelial neoplasia (HGPIN) and proliferative inflammatory atrophy (PIA) are potentially premalignant lesions, found in human prostate (De Marzo et aI., 1999; Bostwick e Qian, 2004). HGPIN have been reported in canine prostate (Waters et aI., 1997), and share the same aspects with the humans, and PIA hadn't been described in the dogs. The aim of this work was to evaluate, by immunohistochemistry proliferative index (PCNA and KI-67), proapoptotic proteins expression (caspase 3), tumour suppressor gene (p-53), adhesion molecules (Ecadherin), histochemical proliferative status (AgNOR) and nuclear measurement by image computer quantitative analysis (AQCI) in HGPIN focus, PIA e normal acinus in canine prostate. Comparing the normal acinus results, the lesions showed higher proliferative index, secretory epithelial cells capable of proliferation, absence of p-53 expression, loss of E-cadherin expression, AgNOR patterns similar to normal acinus, cellular nucleus bigger and with higher nuclear round factor. PIA had the same apoptotic index as the normal acinus and mainly T Iymphocytes in the inflammatory infiltrate. Our findings allow us to consider these two lesions close to each other, and they may be involved in the process of neoplastic transformation of canine prostate. / Orientador: Enio Pedone Bandarra / Coorientador: Luiz Henrique de Araújo Machado / Banca: Renée Laufer Amorim / Banca: Sérgio Luis Felisbino / Banca: Ana Paula F.

Diversos fatores, bem como o processo inflamatório, estão relacionados à carcinogênese prostática. A cicloxigenase-2 (COX-2) apresenta papel fundamental na resposta inflamatória e apresenta relação com o desenvolvimento do câncer de próstata. Este trabalho teve por objetivos caracterizar a proliferação e morte celular (apoptose) das células basais e secretoras do tecido prostático normal e atípico (PIA, PIN e carcinoma) dos cães, avaliar a integridade da camada de células basais por meio do anticorpo p63 e, analisar a expressão gênica de COX-2 nos diferentes componentes teciduais da PIA canina por qRT-PCR. Avaliaram-se, pela técnica de dupla marcação imunoistoquímica, os índices de proliferação e apoptose com os marcadores Ki-67 e caspase-3, respectivamente, das células secretoras (PSA positivas) e das células basais (34âE12 positivas). Para isso, foram estudadas 130 próstatas de cães adultos, inteiros e sem histórico de lesão prostática. Observou-se aumento da proliferação e diminuição da apoptose das células secretoras da PIA e do carcinoma, entretanto, as células basais apresentaram maior índice proliferativo e menor taxa de apoptose apenas nos focos de PIA. Na PIN, a proliferação celular mostrou-se mais evidente em relação à morte celular. Maior quantidade de células basais que expressaram p63 foi constatada na PIA e no carcinoma. Os focos de PIA apresentaram maior expressão gênica de COX-2 no estroma em relação às células epiteliais. Conclui-se que os compartimentos secretor e basal exibem maior proliferação celular e menor taxa apoptótica na PIA. O aumento da marcação de p63 na PIA e no carcinoma sugere participação das... / Dysplastic lesions in human and dogs are prostatic intraepithelial neoplasia (PIN) and proliferative inflammatory atrophy (PIA), which have been investigated because of their premalignant potential. Inflammatory process is related to prostate carcinogenesis. Cyclooxygenase-2 (COX-2) plays a role in the inflammatory response and is correlated with the development of prostate cancer. This study aimed to characterize the proliferation and apoptosis of basal and secretory cells of normal and atypical prostate tissue (PIA, PIN and carcinoma) of dogs, to assess the integrity of the basal cell layer through the p63 immunohistochemistry. In addition, we analyzed the gene expression of COX-2 in different tissue components of canine PIA by qRT-PCR. Immunohistochemical double staining technique was performed using Ki-67 and caspase-3 antibodies to asses cellular proliferation and apoptosis, respectively. PSA was used to characterize the secretory cells and 34âE12 to characterize the basal cells. Were analyzed 130 prostates of adult dogs with or without history of prostatic lesion. Increased proliferation and decreased apoptosis of the secretory cells of the PIA and the carcinoma was observed, however, the basal cells showed higher proliferative index and lower rate of apoptosis only in foci of PIA. PIA and carcinomas showed high expression of p63. It was observed higher gene expression of COX-2 in PIN stroma compared to epithelial cells. We conclude that basal and secretory compartments exhibit higher proliferative and lower apoptotic rate in PIA. The higher expression of p63 in PIA and carcinomas suggests involvement of the basal cells in atypical lesions of the prostate. Furthermore, the expression of COX-2 in PIA is higher in the stromal compartment, revealing important role of this enzyme in the canine prostate carcinogenesis
