Clonagem e avaliação da expressão gênica do sbGnRH em machos juvenis e adultos ...

Este estudo buscou clonar o cDNA do sbGnRH, identificar sua expressão em diferentes tecidos do linguado, bem como avaliar possíveis diferenças no RNA mensageiro (RNAm) desse gene no cérebro de linguados machos juvenis e adultos. Por meio da RT-PCR, demonstrou-se pela primeira vez, a clonagem da região codificadora do sbGnRH contendo 297 nucleotídeos do cérebro do linguado. A expressão do sbGnRH foi detectada em...

Histopathologic and immunohistochemical exam in one case of canine endometrial ...

Canine endometrial carcinomas are rare, and mostly occur in geriatric bitches. In this work, the uterus of a 10-year-old female Boxer evidencing an endometrial carcinoma on the body of the uterus was used to describe the histopathological features of the tumour and to study its immunophenotype. In this work, a panel of immunomarkers (cytokeratins AE1/AE3 and 14, vimentin, CD10 and Ki-67) was applied to the endo...
