Abstract: Antibody compositions and methods for inhibition of the effects of gonadotropin hormones are provided. Methods for treating cancer and methods for regulating fertility are provided by administration of the antibody compositions to a mammalian subject in need thereof.

Abstract: Methods of treating a subject with neoplasm (e.g., mesothelioma) or at risk of developing neoplasm by administering a mevalonate pathway inhibitor such as a nitrogen-containing bisphosphonate are disclosed. Examples of nitrogen-containing bisphosphonates include alendronate, ibandronate, minodronate, neridronate, olpadronate, pamidronate, risedronate, and zoledronate. The methods can further include the administration of a p38 inhibitor. Further disclosed are compositions and kits including a nitrogen-containing bisphosphonate and optionally a p38 inhibitor.

Abstract: Compositions for stimulating the immune system and for treating malignancies associated with overexpression of the HER-2 protein are provided. Such compositions include immunogenic epitopes of the HER-2 proteins and chimeric and multivalent peptides which comprise such epitopes. The present invention also relates to polynucleotides which encode the chimeric peptides. Also provided are pharmaceutical compositions comprising such immunogenic compositions. Methods for stimulating an immune response to HER-2 protein are provided. Methods for treating breast cancer, ovarian cancer, prostate cancer, colon cancer and lung cancer are provided.
