Synergistic effects of bee venom, hesperidin, and piperine with tamoxifen on apoptotic and angiogenesis biomarker molecules against xerographic MCF-7 injected rats.

Breast cancer ranks as the second leading most significant of mortality for women. Studies have demonstrated the potential benefits of natural compounds in cancer treatment and prevention, either in isolation or in conjunction with chemotherapy. In order to improve Tamoxifen's therapeutic efficacy in in-vivo studies, our research sought to determine the effects of hesperidin, piperine, and bee venom as natural compounds, as well as their combination effect with or without Tamoxifen.

Hesperidin, piperine and bee venom synergistically potentiate the anticancer effect of tamoxifen against breast cancer cells.

Despite advances in cancer treatment, breast cancer remains one of the main life threatening diseases in women. Most anti-breast cancer drugs cause severe health complications and multidrug resistance. Although, some natural products, such as hesperidin (Hes), piperine (Pip) and bee venom (BV), showed anti-breast cancer effect when used separately, their combined effect together or with the anti-cancer drug tamoxifen (Tam) has not yet been studied.

Histogenesis of human renal cell carcinoma by using electron microscopy and immunohistochemical techniques.

Electron microscopy and immunohistochemical techniques are powerful tools for the determination of tissue origin. Both techniques have been used in the current experiment for histogenesis of renal cell carcinoma. Fifty kidney tumors were subjected to immunohistochemical detection for intermediate filaments cytokeratin and vimentin, which are normally expressed in epithelial tissue and mesenchymal tissues, respectively.
