TASK: Your task is to answer biomedical questions using the given abstract. Only output yes, no, or maybe as answer.
INPUT: ['Tissue inhibitors of metalloproteinases (TIMPs) are downregulated in the failing human heart. The objective of the present study was to test the hypothesis that cytokines might be involved in the regulation of TIMPs in cardiac cells.', 'Neonatal Sprague-Dawley rat ventricular cells were exposed to 100 units/ml tumor necrosis factor-alpha and/or 5 ng/ml interleukin-1 beta. The mRNA and protein expression of TIMPs-1-4 and disintegrin metalloproteinase was analyzed using Northern blot, ELISA and/or Western blot, respectively. Proteolytic activity and extracellular matrix degradation and turnover were determined using gelatin zymography and pulse-chase experiments.', 'The TIMP-1 mRNA was upregulated in cardiac cells, while TIMP-1 protein levels were unchanged in myocytes but downregulated in non-myocytes. The TIMP-2 expression did not change with the cytokine treatment. TIMP-3 was downregulated at both the mRNA and protein levels in cardiac cells. TIMP-4 protein was transiently increased and then returned to control level. In contrast, disintegrin metalloproteinase mRNA and protein were significantly upregulated in those cells. The gelatinolytic activity and extracellular matrix protein degradation were significantly increased.'] Do proinflammatory cytokines regulate tissue inhibitors of metalloproteinases and disintegrin metalloproteinase in cardiac cells?
OUTPUT:
