Premorphological metabolic changes in human breast carcinogenesis
Malignant breast tissue is characterized by morphological and metabolic changes when compared with normal breast tissue. In this study, the cytochemical measurement of glucose‐6‐phosphate dehydrogenase (G6PD) activity was used to detect abnormal metabolism in breast tissue and to determine whether a...

Zusammenfassung: | Malignant breast tissue is characterized by morphological and metabolic changes when compared with normal breast tissue. In this study, the cytochemical measurement of glucose‐6‐phosphate dehydrogenase (G6PD) activity was used to detect abnormal metabolism in breast tissue and to determine whether abnormal metabolic activity precedes morphological change during human breast carcinogenesis. Normal and benign breast tissue, morphologically normal tissue from cancer‐containing breasts, and malignant breast tissue were studied. In malignant tissue, mean(s.e.m.) G6PD activity was significantly increased when compared with normal and benign tissue (9.69(2.3) versus 27.02(1.7) mean integrated extinction (MIE) × 100, P |
