Systemic Endocrine Instigation of Indolent Tumor Growth Requires Osteopontin
The effects of primary tumors on the host systemic environment and resulting contributions of the host to tumor growth are poorly understood. Here, we find that human breast carcinomas instigate the growth of otherwise-indolent tumor cells, micrometastases, and human tumor surgical specimens located at distant anatomical sites. This systemic instigation is accompanied by incorporation of bone-m...
متن کاملIndolent systemic mastocytosis.
circular macules, less than 1 cm in diameter, located on his trunk and extremities [Figure A]. Wheals and surrounding erythema developed in the lesions after rubbing (positive Darier sign). Laboratory analyses showed mild eosinophilia with an increased total tryptase level of 40 ng/ml. Densitometry was normal. With the strong clinical suspicion of cutaneous mastocytosis, a skin biopsy was perfo...
متن کاملDelayed Diagnosis of Adult Indolent Systemic Mastocytosis
Systemic mastocytosis (SM) is a rare, heterogeneous disorder characterized by infiltration and accumulation of mast cells within multiple organs, most commonly the skin. Given the rarity of the disease and the fact that many of its symptoms are shared by more common disorders, a diagnosis may be delayed or hindered. These patients have an elevated risk of developing potentially life-threatening...
متن کاملEstrogen-stimulated endothelial repair requires osteopontin.
OBJECTIVE Estradiol (E(2)) is known to accelerate reendothelialization and thus prevent intimal thickening and in-stent restenosis after angioplasty. Transplantation experiments with ERalpha(-/-) mice have previously shown that E(2) acts through local and bone marrow cell compartments to enhance endothelial healing. However, the downstream mechanisms induced by E(2) to mediate endothelial repai...
متن کاملTumor-derived osteopontin reprograms normal mammary fibroblasts to promote inflammation and tumor growth in breast cancer.
Breast tumors are characterized by an extensive desmoplastic stroma, abundantly populated by fibroblasts. Cancer-associated fibroblasts (CAF) support tumorigenesis by stimulating angiogenesis, cancer cell proliferation, and invasion. CAF also orchestrate tumor-promoting inflammation in multiple tumor types, including breast cancer. However, the mechanisms through which normal tissue fibroblasts...
