17 beta estradiol/sarcoma

Ovarian function was evaluated in 11 women 16 to 43 years of age at treatment who received doxorubicin, cyclophosphamide, and high doses of methotrexate with or without radiotherapy in adjuvant therapy of soft tissue sarcoma. Five women (16-33 yr old) who received chemotherapy alone or combined with

The multidrug resistance (MDR) gene family has been shown to be highly expressed in several normal tissues including the canalicular membrane of the hepatocyte. We report that a cholestatic estrogen metabolite, 17 beta-estradiol glucuronide (E217G), is a substrate for the MDR transporter,

The androgenic steroid hormone, testosterone, inhibited focus formation by the murine Moloney sarcoma virus in mouse embryo cells. The inhibition of focus formation was enhanced by cyclic AMP. Although focus formation was inhibited, there was no inhibition of viral replication. The glucogenic

When the NGF-secreting C-6 rat glioma cells were intracerebrally injected with F98 rat anaplastic glioma cells into rats syngeneic for the F98 cells, an increased mean survival time was observed for rats developing tumors compared with those injected with only anaplastic glioma cells. Thirty percent

We have demonstrated previously that 17 beta-estradiol (E2) stimulates cell proliferation in skeletal tissues, as measured by increased DNA synthesis and creatine kinase (CK) specific activity, and that calciotrophic hormones modulate E2 activity in rat osteoblastic sarcoma cells (ROS 17/2.8).

Epithelial cells were isolated from mouse endometrium and cultured on two types of extracellular matrix, namely, rat-tail collagen (type I) gels and basement membrane extract (BME) derived from the Engelbreth-Holm-Swarm murine sarcoma. Cell attachment in serum-free medium during the initial 24 h

Glucocorticoids exert potent inhibitory effects on bone formation. We have previously shown that glucocorticoids suppress plasminogen activator (PA) activity in normal and malignant rat osteoblasts. To clarify the mechanism of this suppression, we investigated the effects of dexamethasone on PA

BACKGROUND Patient S. was born in 1983, developed a Ewing-Sarcoma and obtained low dose chemotherapy in 1996. In 2007, Patient S. received high-dose chemotherapy because lung-metastases were diagnosed. The aim of the study was to investigate the health of cryopreserved ovarian tissue and also to

Rhabdomyosarcoma (RMS) is the most common soft tissue sarcoma in children. Highly malignant, RMS frequently fails to respond to conventional aggressive multimodal radiation, surgery, and chemotherapy treatment protocols that also cause significant sequelae in the growing child. Other tumors of

A direct in vitro effect of 17 beta-estradiol (E2) was demonstrated on bone and cartilage cell energy metabolism. Sex-specific stimulation by E2 and testosterone was shown in diaphyseal bone of weanling rats. E2 (30 nM) caused, within 24 hr, a 70-200% increase in creatine kinase (CK; ATP:creatine
