RRx-001 is an anticancer agent that subjects cancer cells to reactive oxygen/ nitrogen species (ROS/RNS) and acts as an epigenetic modifier. We have used a thiol-bearing MRI contrast agent, Gd-LC7-SH, to investigate the pharmacodynamics of RRx-001 in CHP-100 Ewing’s Sarcoma, HT-29 colorectal carcinoma, and PANC-1 pancreatic carcinoma... full article
OBJECTIVE. We describe the significance of detecting focal areas of hypermetabolism in the breast in patients undergoing PET/CT for reasons other than for breast cancer detection or staging.
CONCLUSION. When evaluated, almost all of the abnormal foci detected in the breast subsequently proved to be breast carcinoma, specifically... full article
In a recent issue of Science , Olive and colleagues document that inhibition of Hedgehog (Hh) signaling in a genetically engineered mouse model of pancreatic cancer can enhance the intratumor concentration of certain anticancer drugs. Could this finding provide us with a new method to attack pancreatic cancer?

MicroRNAs are small non-coding RNAs of 21-25 nucleotides that might impact regulatory mechanisms in cancer. Due to their influence on cell physiology, alteration of miRNA regulation can be implicated in carcinogenesis and disease progression. In general, one miRNA is predicted to regulate several hundred genes, and as a result,... full article
This paper reports the development of a biodosimetry device suitable for rapidly measuring expression levels of a low-density gene set that can define radiation exposure, dose and injury in a public health emergency. The platform comprises a set of 14 genes selected on the basis of their abundance and differential expression... full article
Brain metastasis (BM) can affect ~25% of non-small cell lung cancer (NSCLC) patients during their lifetime. Efforts to characterize patients that will develop BM have been disappointing. microRNAs (miRNAs) regulate the expression of target mRNAs. miRNAs play a role in regulating a variety of targets and, consequently, multiple... full article
The ACR’s mission statement identifies five pillars of excellence. One of its pillars is research. ACR is recognized by many as supporting one of the premier research endeavors sponsored by a professional medical society of which the ACR Clinical Research Center is the largest component. The center is comprised of four entities: ACRIN®, RTOG®,... full article
Dynamic Contrast-Enhanced MRI (DCE-MRI) is increasingly in use as an investigational biomarker of response in cancer clinical studies. Proper registration of images acquired at different time-points is essential for deriving diagnostic information from quantitative pharmacokinetic analysis of these data. Motion artifacts in the... full article
