Abstract Background: Circulating tumor cells (CTCs)are the basis of cancer metastasis. Till now, the role of different subtypes of CTCs in metastasis is unclear. Methods: We used the CanpatrolTM technique to isolate CTCs from 102 prostate cancer (PCa) patients. The EMT markers of CTCs were detected by FISH and classified CTCs into Epethial (E-CTCs), Mesenchymal (M-CTCs) and Mesenchymal/Epethial-CTCs (M/E-CTCs). Further, the potential EMT related molecules regulators were predicted by bioinformatics software, and SP1 was identified as the key EMT regulator. Then overexpress SP1 of PCa cells to verify the effect of SP1 on the EMT regulation and PCa metastasis. Results: The count of Total-CTCs, E-CTCs, and M/E-CTCs in metastatic PCa was significantly higher than that in local PCa. Although M-CTCs was not significantly different between local and metastatic PCa, the ratio of M-CTCs/Total-CTCs in metastatic PCa was markedly lower than that in local PCa. We found that Total-CTCs is an independent risk factor for PCa metastasis. Overexpression of SP1 initiated EMT of PCa cells and enhanced the invasion in vitro. Injecting overexpression SP1 PCa cells via tail vein, generating M-CTCs in vivo, we found the ability of M-CTCs to form lung metastasis was significantly inhibited compared with that of the control PCa-CTCs. Conclusion: Our study suggested Total-CTCs >14 predict PCa metastasis. M/E-CTCs might facilitate to PCa metastasis; however, M-CTCs might not. SP1 is an EMT regulator, which has the potential role of regulating the EMT of CTCs, thus changing the proportion of subtypes of CTCs. It is a potential therapeutic target.(Trial registration: Chinese Clinical Trial Registry. Registered 30 JUNE 2020, http://www.chictr.org.cn/registry.aspx)

O presente estudo teve como objetivo avaliar os serviços oferecidos em uma Estratégia de Saúde da Família (ESF) do município de Santo Ângelo (RS). Para isto foi realizada uma pesquisa observacional entre outubro de 2019 e março de 2020, pelos integrantes do Programa Educação pelo Trabalho para a Saúde (PET-Saúde-Interprofissionalidade), com 156 participantes. Foram avaliados atributos utilizando o instrumento de Avaliação da Atenção Primária adaptado à realidade local (PCA-Tool adaptado). Dentre os entrevistados os atributos que apresentaram relevância positiva foram grau de afiliação, com 87,6% dos participantes que procuravam ESF do seu bairro; longitudinalidade, com escore de 8,9; coordenação-sistema de informações, com escore 9,3; integração de cuidados com escore 8,8 e serviços disponíveis na unidade com 8,2; foram os itens mais bem avaliados. Os resultados baixos foram: acessibilidade com escore de 6,9, serviços prestados e orientação comunitária, ambos com escores médios 5,7.  O escore geral de avaliação de todos atributos se apresentou em 7,7. Com isto se evidenciou que a ESF apresenta bom desempenho em vários atributos analisados. Porém, com relação à orientação comunitária, integralidade e serviços prestados, apresenta algumas falhas, evidenciando a necessidade de uma mudança de estratégias, focando mais em orientações voltadas à família e comunidade.

Prostate cancer (PCa) is the most frequent cancer in men. The evolution from local PCa to castration-resistant PCa, an end-stage of disease, is often associated with changes in genes such as p53, androgen receptor, PTEN, and ETS gene fusion products. Evidence is accumulating that repurposing of metformin (MET) and valproic acid (VPA) either when used alone, or in combination, with another therapy, could potentially play a role in slowing down PCa progression. This review provides an overview of the application of MET and VPA, both alone and in combination with other drugs for PCa treatment, correlates the responses to these drugs with common molecular changes in PCa, and then describes the potential for combined MET and VPA as a systemic therapy for prostate cancer, based on potential interacting mechanisms.
