Progression Of Renal Cell Carcinoma Is Inhibited By Genistein And Radiation In An Orthotopic Model, Gilda G. Hillman, Yu Wang, Mingxin Che, Julian J. Raffoul, Mark Yudelev, Omer Kucuk, Fazlul H. Sarkar

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

We have previously reported the potentiation of radiotherapy by the soy isoflavone genistein for prostate cancer using prostate tumor cells in vitro and orthotopic prostate tumor models in vivo. However, when genistein was used as single therapy in animal models, it promoted metastasis to regional para-aortic lymph nodes. To clarify whether these intriguing adverse effects of genistein are intrinsic to the orthotopic prostate tumor model, or these results could also be recapitulated in another model, we used the orthotopic metastatic KCI-18 renal cell carcinoma (RCC) model established in our laboratory.

Methods

The KCI-18 RCC cell line was generated …

Genistein Inhibits Radiation-Induced Activation Of Nf-Κb In Prostate Cancer Cells Promoting Apoptosis And G2/M Cell Cycle Arrest, Julian J. Raffoul, Yu Wang, Omer Kucuk, Jeffrey D. Forman, Fazlul H. Sarkar, Gilda G. Hillman

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

New cancer therapeutic strategies must be investigated that enhance prostate cancer treatment while minimizing associated toxicities. We have previously shown that genistein, the major isoflavone found in soy, enhanced prostate cancer radiotherapy in vitro and in vivo. In this study, we investigated the cellular and molecular interaction between genistein and radiation using PC-3 human prostate cancer cells.

Methods

Tumor cell survival and progression was determined by clonogenic analysis, flow cytometry, EMSA analysis of NF-κB, and western blot analysis of cyclin B1, p21^WAF1/Cip1, and cleaved PARP protein.

Results

Genistein combined with radiation caused greater inhibition in PC-3 …

Near-Infrared Characterization Of Breast Tumors In Vivo Using Spectrally-Constrained Reconstruction, Subhadra Srinivasan, Brian W. Pogue, Ben Brooksby, Shudong Jiang, Hamid Dehghani, Christine Kogel, Wendy A. Wells, Steven P. Poplack, Keith D. Paulsen

Dartmouth Scholarship

Multi-wavelength Near-Infrared (NIR) Tomography was utilized in this study to non-invasively quantify physiological parameters of breast tumors using direct spectral reconstruction. Frequency domain NIR measurements were incorporated with a new spectrally constrained direct chromophore and scattering image reconstruction algorithm, which was validated in simulations and experimental phantoms. Images of total hemoglobin, oxygen saturation, water, and scatter parameters were obtained with higher accuracy than previously reported. Using this spectral approach, in vivo NIR images are presented and interpreted through a series of case studies (n=6 subjects) having differing abnormalities. The corresponding mammograms and ultrasound images are also evaluated. Three of six …
