Background: Patients with breast cancer—the deadliest cancer among women—are at constant risk of developing metastasis. Oxidative stress and hypoxia are common feature of tumor cells that can proliferate even in a resultant metabolic acidosis. Despite the low extracellular pH, intracellular pH of tumor cells remains relatively normal, or even more alkaline due to the action of a membrane protein family known as monocarboxylate transporters (MCTs). The objective of this study was to verify the diagnostic and prognostic value of MCT1, MCT4 and CD147 in tumor and peripheral blood samples of patients with breast cancer undergoing chemotherapic treatment. Methods: Differential expression of MCT1, MCT4 and CD147 obtained by qPCR was determined by 2−ΔΔCq method between biological samples (tumor and serial samples of peripheral) of patients (n = 125) and healthy women (n = 25). Results: tumor samples with higher histological grades have shown higher expression of these markers; this higher expression was also observed in blood samples obtained at diagnosis of patients when compared to healthy women and in patients with positive progression of the disease (metastasis development). Conclusion: markers studied here could be a promising strategy in routine laboratory evaluations as breast cancer diagnosis and prognosis.
O trabalho teve como objetivo descrever o perfil dos cuidadores e das crianças com tetraparesiasegundo suas características, aspectos sociodemográficos e acessibilidade, por meio de um questionáriodesenvolvido e aplicado durante as sessões de fisioterapia, realizadas no setor de neurologia infantildo Centro de Reabilitação Municipal de Santo André. Foram entrevistados 19 cuidadores de criançastetraparéticas com diagnóstico de Paralisia Cerebral. A análise dos resultados mostrou que oscuidadores, em sua maioria, eram as mães das crianças selecionadas e que estas dedicavam-se,integralmente, aos cuidados de seus filhos, abdicando-se de suas atividades profissionais oueducacionais. Enquanto, que as crianças apresentavam importante comprometimento motor (GMFCSV), dependentes para muitas atividades funcionais necessitando de algumas Tecnologias Assistivas.Verificou-se, ainda, pouco conhecimento, por parte dos cuidadores, em relação a esta terminologiaque associado à falta de recursos financeiros podem trazer prejuízos no processo de autonomia,participação e inclusão social destas crianças.
