Finally, Col. 12 presents our proposed classification as GPS, CSS, candidate GPS cG ; and flat spectrum source FS. Cell Lines. The human colon carcinoma cell line, LS174T was grown in supplemented DMEM as described previously 25 ; . Shaw, a human pancreatic carcinoma cell line, and N87, a human gastric carcinoma cell line that expresses high levels of HER2, were grown in supplemented RPMI 1640 7, 26 ; . All media and supplements were obtained from Quality Biologicals Gaithersburg, MD ; . Flow Cytometric Analysis. HER2 expression of the LS174T and Shaw cell lines was assessed with flow cytometric techniques by methods described previously 27 ; . The cells 10, 000 events collected ; were analyzed with a FACSCalibur with CellQuest software BD Biosciences, San Jose, CA ; . Chelate Synthesis and mAb Conjugation. The synthesis, characterization, and purification of the bifunctional ligand, CHX-A-DTPA, has been described previously 28 ; . Herceptin was conjugated with the CHX-A"-DTPA by established methods with a 10-fold molar excess of ligand to mAb 27 ; . Protein was quantified by the method of Lowry and the number of CHX-A" molecules linked to the mAb was determined with the yttrium-Arsenazo III ; based assay 29, 30 ; . Radiolabeling of Herceptin. Radiolabeling of CHX-A"Herceptin with indium-111 [200 g in 0.15 mol L ammonium acetate buffer pH 7.0 ; ] was performed by adding 1 mCi in 1 to 111In chloride Perkin-Elmer, Boston, MA ; . The reaction was quenched after 30 minutes with 0.1 mol L EDTA 3 L ; to scavenge-free radiometal, and the radiolabeled product was purified with a PD-10 desalting column Amersham Biosciences, Piscataway, NJ ; . The labeling of CHX-A"-Herceptin with 213Bi was accomplished as follows. 213Bi 7.8 to 8.4 mCi ; was eluted from a 225 Ac 15 mCi ; generator Oak Ridge National Laboratories. To show no improvement for two years, then I think that what you'll see is a series of clinical trials that will look at shorter duration. CALLER: All right, well, thank you very much. I appreciate that. JANELLE: Thank you. Our next question is coming from Palatine, Illinois. CALLER: Hello, Doctor. These forums are wonderful for breast cancer patients. My question is what response should a patient expect from their oncologist when the patient brings in medical updates or new research to the appointment? And what can you do if the oncologist you respect and honor shows little interest in discussing the research you bring in? ERIC WINER, MD: I love questions like this. I'm always trying to imagine being on the other end of this, that is, the doctor in clinic who frequently has things brought into me. The issue that comes up often is that what is out there in the media sometimes is nothing of great interest and sometimes is of great interest. The hard part for a doctor is explaining to someone what is worth paying attention to versus that which isn't. I think that when you bring something in, someone should be respectful of what you've brought in and should help guide you to see whether this is something that's useful or something that isn't useful. So, for example, for a woman with HER-2-positive breast cancer, bringing in a newspaper clipping or something from the Internet on the adjuvant Herceptin trials would be incredibly significant. On the other hand, bringing in an article about some treatment that was given to 12 rats probably wouldn't be. But I do think that you need to be able to have an open communication with your doctor and feel like what you bring in is something that she or he is paying some attention to. Even if it's a brief conversation, not feel like it's being dismissed out of hand. Does that help? CALLER: Yes, it does. I think patients understand how busy oncologists are. But sometimes when you're looking for things that might help you, you sometimes feel that your interest is not always given attention. It's kind of a struggle.

Thread tools search this thread display modes # 1 , molly n a herceptin hi, all, just heard from my onc brother who is in san francisco for the oncology conference and hms Has been shown to be poorly expressed in arteries while more abundantly expressed in capillaries and venules 30 ; . We confirmed the presence of functional thrombin receptors in both BAEC and BMVEC by observing an increase in [Ca 2 + ]i after thrombin challenge in both types of cells. Although these results indicate the presence of functional thrombin receptors, they do not explain the lack of thrombin permeability effects in BAEC. Overall, these results emphasize endothelial heterogeneity with regard to barrier function and underscore the importance of evaluating the appropriate endothelial cell type. To conclude, this study represents the first report of successful isolation and characterization of vascular endothelial cells derived from the airway microvasculature. While assessing macromolecule permeability across confluent monolayers, BMVEC showed a less restrictive barrier than BAEC. Both endothelial cell types responded similarly to bradykinin, however, only microvascular endothelial cells were sensitive to thrombin. This study establishes an improved methodologic approach to the study of mechanisms of airway vascular endothelial barrier dysfunction.
Genentech, the biotechnology firm that developed the drug Herceptin, is seeking subjects for several clinical trials now in progress. Women with metastatic disease who have already undergone treatment with an anthracycline such as Adriamycin ; and a taxane such as Taxol or Taxotere ; are sought for a trial involving an anti-angiogenesis treatment known as anti-VEGF vascular endothelial growth factor ; , which inhibits the growth of tumors by cutting off their blood supply. This phase III trial is studying anti-VEGF in combination with the chemotherapy drug capecitabine sold under the trade name Xeloda ; . Subjects will be randomly assigned to receive one of two treatments capecitabine alone or capecitabine plus anti-VEGF and treatment will last up to 105 weeks. Like Herceptin, the anti-VEGF approach is novel because it targets a particular aspect of tumor biology rather than attacking all cells. The approach is not without its safety concerns, however: subjects in earlier clinical studies of anti-VEGF have suffered life-threatening toxicities such as hemorrhage in patients with primary lung cancer ; and thrombosis, as well as less severe toxicities, including hypertension, protein in the urine, fever, chills, rash, and headache. For more information about this trial, call Genentech toll-free at 888 662-6728. Women with early-stage breast cancer are sought for four different phase III clinical trials to determine the safety and efficacy of adding Herceptin to chemotherapy in the adjuvant setting. These trials are investigating Herceptin as a potential adjuvant treatment option for women who have breast cancer tumors that are HER-2 human epidermal growth factor receptor-2 ; positive, indicating a more aggressive disease and a poorer prognosis. About 25 to 30 percent of women with breast cancer have tumors that are HER-2 positive, and research indicates that these women have a greater likelihood of recurrence. Two of the trials will evaluate the combination of doxorubicin and cyclophosphamide AC ; followed by paclitaxel, with and without Herceptin, using different schedules of paclitaxel. A third trial will evaluate AC followed by doxetaxel with and without Herceptin. The fourth trial will evaluate Herceptin following any chemotherapy regimen for the adjuvant treatment of high-risk breast cancer. For more information about these trials, call the National Cancer Institute's Cancer Information Service at 800 4-CANCER, or visit cancertrials.nci.nih.gov. download one from the FDA's Web site at fda.gov cdrh consumer record card . Women who undergo a chest X-ray should try to have the rays directed at their back instead of their chest, to diminish the amount of radiation that reaches the breasts. "If the exam can be done instead from back to front, the breasts will receive a much lower X-ray dose, " says Gofman. Though Gofman finds the resistance on the part of the medical community to investigate ways to limit exposure quite puzzling not to mention frustrating he believes that under pressure from individuals, health care providers will be forced to reconsider current practice. "There is no mystery about how to reduce doses, technically, " says Gofman. "What is lacking is leadership. If just a few thousand radiologists would openly endorse the goal to bring doses down, their leadership could reduce the average level administered by other radiologists virtually overnight." John Gofman will be discussing the issues raised in this article during a workshop at BCA's fourth annual town meeting. See the calendar on page 1 for ticket information. N and humalog.
