Breast cancer patients, who are already at increased risk of developing bone metastases and osteolytic bone damage, are often treated with doxorubicin. Unfortunately, doxorubicin has been reported to induce damage to bone. Moreover, we have previously reported that doxorubicin treatment increases circulating levels of TGFβ in murine pre-clinical models.(More)
Cytogenetic analyses of meiotic metaphase I germ cells and abnormalities of head morphology of caudal sperms were conducted in male mice following oral feeding of Pan Masala. The substance was ground to a fine powder, dispersed in polysorbate solution and administered via gavage to the animals at 84, 420 and 840 mg/kg body weight at the rate of 10 ml/kg(More)
It is generally argued that micronuclei and micronuclei premature chromosome condensation (MN PCC) in stable cell lines occur only after treatment with potent clastogens, mutagens or carcinogens. In the present paper we report on the occurrence of micronuclei and MN PCC (predominantly of S type) at a high frequency in a mixed in vivo culture of prearrested(More)
Breast cancer often metastasizes to bone causing osteolytic bone resorption which releases active TGFβ. Because TGFβ favors progression of breast cancer metastasis to bone, we hypothesized that treatment using anti-TGFβ antibody may reduce tumor burden and rescue tumor-associated bone loss in metastatic breast cancer. In this study we have tested the(More)
The acute and chronic oral toxicity of pan masala (betel quid without betel leaf) was assessed in gavage studies in rats. Clinical parameters (liver and serum glutamic-oxaloacetic transaminase, glutamic-pyruvic transaminase and alkaline phosphatase) and organ weights were measured. The results indicate that chronic feeding of pan masala impaired liver(More)
Chromosome studies of Dalton's lymphoma, which was originally developed in the DBA/2 mouse and later adapted to a close inbred strain of the Swiss albino mouse, revealed only one rb-marker in all cells bearing a modal number (71). After several successive in vivo passages of the tumor, a new cell clone appeared with a different modal number (70) and two(More)
