Expression of BCRP in Icteric Patients

The expression of transporters involved in bile acid homeostasis is differentially regulated during obstructive cholestasis. Bile acids are also substrates of the drug efflux transporter breast cancer resistance protein (BCRP) that is highly expressed in the human intestine. Therefore we intend to analyze whether intestinal BCRP expression could be altered during cholestasis.

Role of Gene Variation in Effectiveness of Gleevec Treatment

This study will examine DNA from cancer patients previously treated with Gleevec to look for a variation (mutation) of the ABCG2 gene that may render the drug less effective in certain patients. Gleevec is used to treat chronic myeloid leukemia and gastrointestinal tumors. Although most patients respond to treatment, many with advanced disease develop resistance to the drug. It is thought that in some patients this resistance results from the action of a protein that causes Gle...

Serum Proteomics to Predict Gemcitabine Sensitivity in Breast Cancer

Tumors are heterogeneous with varying response to chemotherapeutic agents. We hypothesize that tumors that are sensitive to a particular chemotherapeutic agent have a distinctive tumor protein profile compared to those that are resistant. We further hypothesize that since tumor is continuously perfused by serum, serum protein profile can be used as a surrogate marker of tumor protein profile. The primary objective of this study is to identify a serum protein profile that predic...

Dose Response of Whey and Soy Protein Ingestion With and Without Resistance Exercise in Elderly Men

When we age, we lose muscle. It is not exactly clear why this happens, but we do know that this muscle loss can increase health risks and lead to health problems. Lifting weights (i.e. performing resistance exercise) and proper nutrition, in particular eating enough high quality protein, can help slow the loss of muscle mass or potentially even reverse it. Protein and resistance exercise are thought to do this by stimulating your muscle to make more proteins and/or potentially ...

Analysis of the Role of Hepatocyte SLAMF3 Receptor and Drug Resistance Proteins (MDR) in Resistance to Treatment With Sorafenib in CHC Patients

Primary liver cancer or hepatocellular carcinoma (HCC) is the 7th most common cancer in humans; 9th in women (figures from the Association for Research against Cancer ARC). This cancer is a major public health problem on a global scale. Patients, whose diagnosis is often late, are at advanced stages of the pathology, even those who benefit from locoregional treatments have a poor prognosis and suffer from a lack of curative therapeutic strategies. CHC is highly refractory to cy...

Effects of Protein Timing and Resistance Exercise on Fat Metabolism

The extent to which resistance exercise training and protein timing effects localized (belly fat) and systemic (whole body) fat metabolism in resistance-trained women is unknown. Therefore, this study will assess subcutaneous abdominal adipose tissue lipolytic rate and whole body substrate utilization over the course of two trials: 1) consuming casein protein during the day, and 2) consuming casein protein at night, before bed.

Novel Capecitabine Dosing Schedule in Combination With Lapatinib, Based on the Norton-Simon Mathematical Method in Patients With HER2 Overexpressed/Amplified, Trastuzumab (Herceptin) -Refractory, Metastatic Breast Cancer

HER2 is a protein that sits on the surface of breast cancer cells in some people. Because you are one of these people, your breast cancer is called "HER2-positive." The HER2 protein is involved in the growth of your breast cancer. Certain drugs can interfere with the ability of the HER2 protein to cause breast cancer growth. Trastuzumab is one of these drugs. You must have already received trastuzumab as treatment for your breast cancer to be considered for this study. O...
