          Abstract

          Background:

          Pancreatic ductal adenocarcinoma is the fourth leading cause of cancer-related mortality. Efforts to improve cancer treatment through nanotechnology are at the developmental stage, and it will be gracious if the drug with anticancer property itself is a nanoparticle. Bhasma is organomineral complexes which are bioactive nanoparticles. Yashada Bhasma (incinerated processed zinc) is widely used in Ayurveda for various diseases, and there are evidence that ZnO nanoparticles are promising antitumor agent. However, no studies have been conducted on the effectiveness of Yashada Bhasma in pancreatic cancer.

          Materials and Methods:

          Two types of test drugs, Parada Marita Yashada Bhasma (PMY) and Vanaspati Jarita Marita Yashada Bhasma (JMY), were prepared as per the guidelines of pharmaceutics of Ayurveda. Particle size analyses of Yashada Bhasma and Zeta potential study was carried out initially. Further human pancreatic cancer cell line (MIA PaCa-2) study was done using in vitro sulforhodamine B assay, keeping adriamycinas control. After 48 h of incubation, antiproliferative effects were assessed.

          Results:

          JMY and adriamycin showed dose-dependent growth inhibition of cancer cells. Both Yashada Bhasma samples showed a cytostatic effect at this concentration.

          Conclusion:

          The study leads to new avenues for cancer treatment by developing such unique and highly effective bioactive nano-sized therapeutic agent.

          The clinical relevance of cancer cell lines.

          Although advances in genomics during the last decade have opened new avenues for translational research and allowed the direct evaluation of clinical samples, there is still a need for reliable preclinical models to test therapeutic strategies. Human cancer-derived cell lines are the most widely used models to study the biology of cancer and to test hypotheses to improve the efficacy of cancer treatment. Since the development of the first cancer cell line, the clinical relevance of these models has been continuously questioned. Based upon recent studies that have fueled the debate, we review the major events in the development of the in vitro models and the emergence of new technologies that have revealed important issues and limitations concerning human cancer cell lines as models. All cancer cell lines do not have equal value as tumor models. Some have been successful, whereas others have failed. However, the success stories should not obscure the growing body of data that motivates us to develop new in vitro preclinical models that would substantially increase the success rate of new in vitro-assessed cancer treatments.

            Zinc supplementation augments in vivo antitumor effect of chemotherapy by restoring p53 function.

            Activated p53 is necessary for tumor suppression. Homeodomain-interacting protein kinase-2 (HIPK2) is a positive regulator of functional p53. HIPK2 modulates wild-type p53 activity toward proapoptotic transcription and tumor suppression by the phosphorylation of serine 46. Knock-down of HIPK2 interferes with tumor suppression and sensitivity to chemotherapy. Combined administration of adriamycin and zinc restores activity of misfolded p53 and enables the induction of its proapoptotic and tumor suppressor functions in vitro and in vivo. We therefore looked for a cancer model where HIPK2 expression is low. MMTV-neu transgenic mice overexpressing HER2/neu, develop mammary tumors at puberty with a long latency, showing very low expression of HIPK2. Here we show that whereas these tumors are resistant to adriamycin treatment, a combination of adriamycin and zinc suppresses tumor growth in vivo in these mice, an effect evidenced by the histological features of the mammary tumors. The combined treatment of adriamycin and zinc also restores wild-type p53 conformation and induces proapoptotic transcription activity. These findings may open up new possibilities for the treatment of human cancers via the combination of zinc with chemotherapeutic agents, for a selected group of patients expressing low levels of HIPK2, with an intact p53. In addition, HIPK2 may serve as a new biomarker for tumor aggressiveness. Copyright © 2011 UICC.

              Preparation and characterization of a copper based Indian traditional drug: tamra bhasma.

              The copper based Indian traditional drug 'tamra bhasma' is administered for various ailments since long. Its synthesis involves treating metallic copper with plant juices and then repeated calcination in presence of air so that the metallic state is transformed into the corresponding oxide form traditionally known as 'bhasma'. In this work, we present a systematic characterization of this traditional drug using various techniques like X-ray diffraction (XRD), scanning electron microscopy (SEM)-energy dispersive X-ray analysis (EDX), X-ray photoelectron spectroscopy (XPS), infrared spectroscopy (IR), thermogravimetry (TG) and surface area measurement. The results obtained were found to match very well with those of a standard copper oxide confirming the composition of the drug sample. In addition, some specific findings were also made which could help in interpreting the therapeutic properties of the traditional drug 'tamra bhasma'.
