In a sample of blood, researchers probe for cancer clues

One day, patients may be able to monitor their body's response to cancer therapy just by having their blood drawn. A new study has taken an important step in that direction by measuring a panel of cancer proteins in rare, individual tumor cells that float in the blood.

Abstract OBJECTIVES: To assess post-traumatic stress symptoms (PTSSs) in young adult survivors of childhood cancer not receiving survivorship care and to determine whether attending a survivorship-focused healthcare visit was associated with changes in PTSSs. SAMPLE & SETTING: 44 young adult survivors from the Yale Cancer Center in Connecticut without prior survivorship clinic attendance. METHODS & VARIABLES: As part of a larger trial, participants were randomized to a model of survivorship-focused health care. The University of California at Los Angeles Post-Traumatic Stress Disorder (PTSD) Reac...

To reduce this high mortality, more effective chemotherapy, allowing a specific tumor accumulation and an efficient early-stage medical imaging as well, are still needed. At this regard, stimuli-responsive nanocarriers for anticancer drug deli...

Long non‑coding RNA ENST00000547547 inhibits cell proliferation, invasion and migration in colorectal cancer cells. Oncol Rep. 2018 Oct 31;: Authors: Ai X, Lei Q, Shen X, Li J, Cen C, Xie G, Luo B, Zhu W, Hu G, Wu H, Chen M, Li X, Lin C Abstract Colorectal cancer (CRC) is one of the most common and lethal types of cancer worldwide. Multiple lines of evidence have illustrated that long non‑coding RNAs (lncRNAs) are critical molecules in the regulation of CRC development and progression. The identification of new lncRNAs is expected to provide new biomarkers and potential therapeutic targets for CRC ...

Authors: Mrowczynski OD, Madhankumar AB, Sundstrom JM, Zhao Y, Kawasawa YI, Slagle-Webb B, Mau C, Payne RA, Rizk EB, Zacharia BE, Connor JR Abstract Radiation is utilized in the therapy of more than 50% of cancer patients. Unfortunately, many malignancies become resistant to radiation over time. We investigated the hypothesis that one method of a cancer cell's ability to survive radiation occurs through cellular communication via exosomes. Exosomes are cell-derived vesicles containing DNA, RNA, and protein. Three properties were analyzed: 1) exosome function, 2) exosome profile and 3) exosome uptake/blockade. To an...

AbstractTargeted radionuclide therapy (TRT) is unique because of its efficacy and its theranostic feature in the era of precision medicine. So far, introduction of new TRT has not been going well in Japan due to several reasons including strict regulations, shortage of facilities for TRT, and insufficient reimbursement for TRT in clinic. Japanese community had several strategies to develop TRT in these 10  years, including the establishment of the National Conference for Nuclear Medicine Theranostics in which physicians, scientists, patients, people supporting patients, and industrial people gather. To promote TRT wit...

The nucleolus is a dynamic structure that has roles in various physiological and pathophysiological processes. Perturbations on many aspects of the nucleolar functions are thought to cause “nucleolar stress”, which occurs in response to a variety of chemotherapeutic drugs. The main characteristic changes of nucleolar stress include: 1) reduction of the size and volume of the nucleolus; 2) inhibition of RNA Pol I-mediated rRNA synthesis; and 3) nucleoplasmic translocation of nucleolar stress-related proteins. In studying the apoptosis-inducing effect of the natural compound lovastatin (LV) on breast cancer stem ...

With the development of cancer treatments, it has become a popular research focus that mesenchymal stem (or stromal) cells (MSCs) have the functional mechanisms that influence cancer progression. One of the underestimated mechanisms is secretion of highly specialized double-membrane structures called exosomes. Mesenchymal stem cells generate several exosomes that may act as paracrine mediators by exchanging genetic information. MSC-derived exosomes are microvesicles ranging from approximately 60-200 nm in size and detected in various body fluids. It has been demonstrated that MSC-derived exosomes are involved in tumor grow...

Conclusion: We reported the synergistic anti-tumor efficacy of ZD55-IL-24 and DTX on prostate cancer. Our results suggest that chemotherapy combined with oncolytic adenovirus mediated gene therapy is a promising strategy for the treatment of advanced prostate cancer.
