1. Human polyomaviruses and cancer: an overview
The name of the family Polyomaviridae, derives from the early observation that cells infected with murine polyomavirus induced multiple (poly) tumors (omas) in immunocompromised mice. Subsequent studies showed that many members of this family exhibit the capacity of mediating cell transformation and tumorigenesis in different experimental models. The transfo

2. Alterations in the expression and activity of extracellular matrix components in HPV-associated infections and diseases
Infection with human papillomaviruses is associated with a series of benign and malignant hyperproliferative diseases that impose a heavy burden on human populations. A subgroup of mucosal human papillomavirus types are associated with the majority of cervical cancers and a relevant fraction of vulvar, vaginal, anal, penile and head and neck carcinomas. Huma

3. Interação de oncoproteínas virais E6 e E7 de HPV16/18 com alvos celulares potenciais para o desenvolvimento de estratégias terapêuticas. / Interaction of E6 and E7 viral oncoproteins of HPV16/18 with potential cellular targets to the development of therapeutic strategies.
O potencial oncogênico do papilomavírus humano (HPV) baseia-se na capacidade das oncoproteínas virais E6 e E7 alterarem o ciclo celular, levando à imortalização e malignidade das células. O importante papel das oncoproteínas na progressão tumoral e na interação com inúmeros alvos celulares tem relevância em estudos para o desenvolvimento de vaci

4. Enhanced anti-tumor effect of a gene gun-delivered DNA vaccine encoding the human papillomavirus type 16 oncoproteins genetically fused to the herpes simplex virus glycoprotein D
Anti-cancer DNA vaccines have attracted growing interest as a simple and non-invasive method for both the treatment and prevention of tumors induced by human papillomaviruses. Nonetheless, the low immunogenicity of parenterally administered vaccines, particularly regarding the activation of cytotoxic CD8+ T cell responses, suggests that further improvements

5. Relação entre o oncogene BCR-ABL e os receptores de tipo TOLL (TLR). / Relationship between the oncogene BCR-ABL and Toll-like receptors (TLR).
Recentemente, a expressão gênica dos receptores TLR foi encontrada em diversos tipos de células tumorais. A sua participação na biologia do câncer é controversa já que foram descritas ações pró e anti-tumorais após a ativação de sua sinalização. Na Leucemia Mielóide Crônica (LMC) nada se tem demonstrado. BCR-ABL é uma oncoproteína quimér

6. Caracterização de metaloproteinases de matriz e reck em queratinócitos primários que expressam oncoproteínas do papilomavírus humano (HPV) / Characterization of matrix metalloproteinases and reck in primary keratinocytes that express human papillomavirus (HPV) oncoproteins
Os tumores da cérvice-uterina, que representam uma das principais doenças ginecológicas em mulheres na idade reprodutiva em todo o mundo, estão etiologicamente associados com a infecção pelo papilomavírus humano (HPV). A progressão de uma lesão intraepitelial escamosa de baixo-grau (LSIL) a um carcinoma invasivo de cérvix uterina está acompanhada

7. Development of a therapeutic vaccine against HPV16 / Desenvolvimento de vacina terapêutica contra HPV16
Cervical cancer is the second most common cancer among women worldwide. Most cases (83%) occur in developing countries, where they are found in relatively advanced stages and, consequently, the median survival is about 49% after five years. Therefore, an effective vaccine against HPV infections can lead to control of cancer of the cervix. Although preventabl

8. Tumores mamários mistos caninos : análise do DNA mitocondrial e da expressão protéica de HER2 e EGFR nos componentes epitelial e mesenquimal.
Benign mixed tumors are histologically characterized by a mixture of epithelial and mesenchymal components. These are common neoplasias in canine mammary glands and can malignize developing carcinomas in benign mixed tumors. The cell origin of the different components that compose mixed tumors and the aspects that determine its malignant transformation remai

9. Mutação em NRAS causa uma síndrome autoimune linfoproliferativa humana / NRAS mutation causes a human autoimmune lymphoproliferative syndrome
The p21 RAS subfamily of small GTPases, including KRAS, HRAS, and NRAS, regulates cell proliferation, cytoskeletal organization and other signaling networks, and is the most frequent target of activating mutations in cancer. Activating germline mutations of KRAS and HRAS cause severe developmental abnormalities leading to Noonan, cardio-facial-cutaneous and

10. Efeito da rapamicina em culturas organotípicas de queratinócitos que expressam oncoproteínas de papiloma vírus humano tipo 16 / Effect of rapamycin in organotypic cultures of keratinocytes expressing oncoproteins of Papillomavirus type 16
A infecção por HPV de alto risco é considerada um dos principais fatores de risco para o desenvolvimento do carcinoma do colo uterino, um das neoplasias mais freqüentes em mulheres de todo o mundo. As oncoproteínas E6 e E7 de HPV-16 são capazes de induzir a degradação dos genes supressores de tumor p53 e pRb, respectivamente. Mais do que isso, a expr

11. Low frequency of p53 mutations in cervical carcinomas among Brazilian women
Human papillomavirus (HPV) infections of the high-risk types are strongly linked to the development of cervical carcinoma. The HPV oncoproteins E6 and E7 are thought to play a crucial role in this process through their interactions with the p53 protein and the retinoblastoma susceptibility gene product pRb, respectively. E6 binds to p53 protein promoting its

12. Degradation of nuclear oncoproteins by the ubiquitin system in vitro.
Nuclear oncoproteins are among the most rapidly degraded intracellular proteins. Previous work has implicated the ubiquitin-mediated proteolytic system in the turnover of short-lived intracellular proteins. In the present study, we have evaluated the potential role of the ubiquitin system in the degradation of the specific nuclear oncoproteins encoded by the
