Cancer with low cathepsin D levels is susceptible to vacuolar (H+)‐ATPase inhibition
Vacuolar (H+ )-ATPases (V-ATPases) have important roles in the supply of nutrients to tumors by mediating autophagy and the endocytic uptake of extracellular fluids. Accordingly, V-ATPases are attractive therapeutic targets for cancer. However, the clinical use of V-ATPase inhibitors as anticancer drugs has not been realized, possibly owing to their high toxicity in humans. Inhibition of V-ATPa...
متن کاملEffects of Endurance Training on the Expression of Cathepsin B (CTSB) and Cathepsin L (CTSL) genes in the Adipose Tissue of Mice with a High-Fat Diet
Introduction: In high-fat diet-induced obesity, the levels of cathepsin L (CTSL) and cathepsin B (CTSB) increase in adipocytes, resulting in insulin resistance in the adipose tissue. In this study, the preventive effect of endurance training on the gene expression of CTSL and CTSB was investigated in the adipose tissue of mice with a high-fat diet. Materials and Methods: Twenty-one male mice (a...
متن کاملCathepsin B inhibition limits bone metastasis in breast cancer.
Metastasis to bone is a major cause of morbidity in breast cancer patients, emphasizing the importance of identifying molecular drivers of bone metastasis for new therapeutic targets. The endogenous cysteine cathepsin inhibitor stefin A is a suppressor of breast cancer metastasis to bone that is coexpressed with cathepsin B in bone metastases. In this study, we used the immunocompetent 4T1.2 mo...
متن کاملSecreted cathepsin L generates endostatin from collagen XVIII.
Endostatin, an inhibitor of angiogenesis and tumor growth, was identified originally in conditioned media of murine hemangioendothelioma (EOMA) cells. N-terminal amino acid sequencing demonstrated that it corresponds to a fragment of basement membrane collagen XVIII. Here we report that cathepsin L is secreted by EOMA cells and is responsible for the generation of endostatin with the predicted ...
متن کاملCathepsin B inhibition prevents trypsinogen activation and reduces pancreatitis severity.
Intrapancreatic activation of trypsinogen is believed to play a critical role in the initiation of acute pancreatitis, but mechanisms responsible for intrapancreatic trypsinogen activation during pancreatitis have not been clearly defined. In previous in vitro studies, we have shown that intra-acinar cell activation of trypsinogen and acinar cell injury in response to supramaximal secretagogue ...
