Human papillomavirus is not associated to non-small cell lung cancer: data from...
Silva, Estela Maria; Mariano, Vânia Sammartino; Pastrez, Paula Roberta Aguiar; Pinto, Miguel Cordoba; Nunes, Emily Montosa; Sichero, LauraBackground: The pathogenesis of lung cancer is triggered by a combination of genetic and environmental factors, being the tobacco smoke the most important risk factor. Nevertheless, the incidence of lung cancer in non-smokers is gradually increasing, which demands the search for different other etiological factors such as occupational exposure, previous lung disease, diet among others. In the early 80's a theor...
Regulation of HPV transcription
Ribeiro, Aline Lopes; Caodaglio, Amanda Schiersner; Sichero, LauraHuman papillomavirus infection is associated with the development of malignant and benign neoplasms. Approximately 40 viral types can infect the anogenital mucosa and are categorized into high- and low-risk oncogenic human papillomavirus, depending on their association with the development of cervical carcinoma. High-risk human papillomavirus 16 and 18 are detected in 55% and 15% of all invasive cervical squamo...
Epidemiology and biology of cutaneous human papillomavirus
Nunes, Emily M.; Talpe-Nunes, Valéria; Sichero, LauraCutaneous human papillomaviruses (HPVs) include b- and g-HPVs, in addition to a small fraction of a-HPVs. b-HPVs were first isolated from patients with the rare genetic disorder Epidermodysplasia verruciformis, and they are associated with the development of nonmelanoma skin cancer at sun-exposed skin sites in these individuals. Organ transplant recipients also have greater susceptibility to b-HPV infection of ...

Calmon, Marilia Freitas [UNESP]; Sichero, Laura; Boccardo, Enrique; Villa, Luisa Lina; Rahal, Paula [UNESP]Made available in DSpace on 2018-11-26T16:54:55Z (GMT). No. of bitstreams: 0 Previous issue date: 2016-09-01; Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP); Annexin 1 (ANXA1) is a substrate for E6AP mediated ubiquitylation. It has been hypothesized that HPV 16 E6 protein redirects E6AP away from ANXA1, increasing its stability and possibly contributing to viral pathogenesis. We analyzed ANXA1 ex...
