Abstract
Cyclophosphamide (CP) is one of the widely used anticancer agents; however, it has serious deleterious effects on normal host cells due to its nonspecific action. The essential trace element Selenium (Se) is suggested to have chemopreventive and chemotherapeutic efficacy and currently used in pharmaceutical formulations. Previous report had shown Nano-Se could protect CP-induced hepatotoxicity and genotoxicity in normal Swiss albino mice; however, its role in cancer management is still not clear. The aim of present study is to investigate the chemoprotective efficacy of Nano-Se against CP-induced toxicity as well as its chemoenhancing capability when used along with CP in Swiss albino mice against Ehrlich's ascites carcinoma (EAC) cells. CP was administered (25 mg/kg b.w., i.p.) and Nano-Se was given (2 mg Se/kg b.w., p.o.) in concomitant and pretreatment schedule. Increase levels of serum hepatic marker, hepatic lipid peroxidation, DNA damage, and chromosomal aberration in CP-treated mice were significantly (P < 0.05) reversed by Nano-Se. The lowered status of various antioxidant enzymes in tumor-bearing mice after CP treatment was also effectively increased by Nano-Se. Administration of Nano-Se along with CP caused a significant reduction in tumor volume, packed cell volume, viable tumor cell count, and increased the survivability of the tumor-bearing hosts. The results suggest that Nano-Se exhibits significant antitumor and antioxidant effects in EAC-bearing mice. The potential for Nano-Se to ameliorate the CP-evoked toxicity as well as to improve the chemotherapeutic effect could have beneficial implications for patients undergoing chemotherapy with CP.

Abstract
Ursolic acid (UA) is a pentacyclic triterpene naturally occurring in many plant foods. In the present study, we investigated anti-cancer activity of UA in vivo in Ehrlich ascites carcinoma (EAC) tumor. 15 × 10(6) EAC cells were implanted intraperitoneally (i.p., ascitic tumor) and subcutaneous (s.c., solid tumor) in Swiss albino mice. Mice with established tumors received UA i.p. at 25, 50 and 100mg/kg bw for 14 d in ascitic and 100mg/kg bw in solid tumor for 30 d. On day 15, blood samples were collected for hematological assessment of hemoglobin (Hb%), RBCs, WBCs and PCV. Tumor volume, cell viability, angiogenic, anti-angiogenic, anti-inflammatory factors and antioxidant parameters were determined. Immunohistochemistry analysis for VEGF, iNOS, CD31, caspase-3 and Bax were also performed. UA significantly inhibited tumor growth, cell viability, in both ascites and solid tumor model in vivo (p<0.001). The anti-angiogenic effects were accompanied with decreased VEGF, iNOS, TNF-α and increased IL-12 levels. UA at 100mg/kg bw dose significantly increased SOD and CAT activity (p<0.01). GSH and TBARS were increased as compared to control group (p<0.001). Furthermore, UA increased total RBCs, WBCs as well as Hb% significantly (p<0.05) compared to cyclophosphamide (CP). Histopathological examination of tumor cells in the treated group demonstrated signs of apoptosis with chromatin condensation and cell shrinkage. Decreased peritoneal angiogenesis showed the anti-angiogenic potential. UA downregulated VEGF & iNOS expression whereas bax and caspase-3 expressions were upregulated suggesting drug induced tumor cell apoptosis through activating the pro-apoptotic bcl-2 family and caspase-3 and downregulation of VEGF. The present study sheds light on the potent antitumor property of the UA and can be extended further to develop therapeutic protocols for treatment of cancer.

Abstract
Boswellic acid (BA), a triterpene, isolated from Boswellia serrata (Burseraceae) has been found to possess potent anti-inflammatory and anti-cancer activity. The present study aimed at exploring the possible role of BA on ascites and solid Ehrlich tumor. Ascitic tumor development was evaluated 14 d after tumor implantation by quantification of the ascitic fluid volume whereas solid tumor was evaluated after 30 d tumor implantation by H&E and IHC. The i.p. administration of BA significantly inhibited ascitic and solid Ehrlich tumor model. This inhibition was observed with reduced ascitic volume, solid tumor volume and body weight when compared to control mice. The treatments also increased the survival of tumor-bearing mice. VEGF and TNF- α levels were decreased, whereas the IL-12 levels were increased with BA treatment at 25mg/kg. Further, results on decrease in the peritoneal angiogenesis and microvessel density showed the anti-angiogenic potential. Microscopic examination of tumors revealed that in BA-treated groups the expression of Bax and caspase 3 increased, suggesting drug induced tumor cell apoptosis through activating the pro-apoptotic bcl-2 family and caspase-3. The present study sheds light on the potent antitumor property of the boswellic acid and can be extended further to develop therapeutic protocols for treatment of cancer.

Abstract
Water-soluble low-molecular weight chitosan (LMWC) and chitooligosaccharides (COs) were obtained from chitosan (16% N-acetylation) by depolymerization induced by potassium persulfate under nitrogen atmosphere for 2 h. They were characterized by IR, X-ray, HPLC and (13)C-NMR. Splitting of C3/C5 signals in the latter indicated a newer conformation, and also showed prominence of acetyl groups in LMWC, may be due to cleavage between two consecutive deacetylated residues. Molecular weight of LMWC, determined by HPSEC, showed a single peak of approximately 37 kDa. HPLC analysis of the solvent-extracted fraction revealed COs enriched with pentamer, hexamer and higher oligomers. The effect of LMWC and COs on the growth of Ehrlich ascites tumor (EAT) cells and tumor-induced neovascularization was studied. COs (50 microg) were more effective compared to LMWC (100 microg) and proved to be potent angioinhibitory and antitumor compounds, as shown by inhibition of angiogenesis and inducing apoptosis as a function of DNA fragmentation.

Abstract
Modulation of pathological angiogenesis by curcumin (diferuloylmethane), the active principle of turmeric, seems to be an important possibility meriting mechanistic investigations. In this report, we have studied the effect of curcumin on the growth of Ehrlich ascites tumor cells and endothelial cells in vitro. Further, regulation of tumor angiogenesis by modulation of angiogenic ligands and their receptor gene expression in tumor and endothelial cells, respectively, by curcumin was investigated. Curcumin, when injected intraperitoneally (i.p) into mice, effectively decreased the formation of ascites fluid by 66% in EAT bearing mice in vivo. Reduction in the number of EAT cells and human umbelical vein endothelial cells (HUVECs) in vitro by curcumin, without being cytotoxic to these cells, is attributed to induction of apoptosis by curcumin, as is evident by an increase in cells with fractional DNA content seen in our results on FACS analysis. However, curcumin had no effect on the growth of NIH3T3 cells. Curcumin proved to be a potent angioinhibitory compound, as demonstrated by inhibition of angiogenesis in two in vivo angiogenesis assay systems, viz. peritoneal angiogenesis and chorioallantoic membrane assay. The angioinhibitory effect of curcumin in vivo was corroborated by the results on down-regulation of the expression of proangiogenic genes, in EAT, NIH3T3, and endothelial cells by curcumin. Our results on Northern blot analysis clearly indicated a time-dependent (0-24h) inhibition by curcumin of VEGF, angiopoietin 1 and 2 gene expression in EAT cells, VEGF and angiopoietin 1 gene expression in NIH3T3 cells, and KDR gene expression in HUVECs. Further, decreased VEGF levels in conditioned media from cells treated with various doses of curcumin (1 microM-1mM) for various time periods (0-24h) confirm its angioinhibitory action at the level of gene expression. Because of its non-toxic nature, curcumin could be further developed to treat chronic diseases that are associated with extensive neovascularization.
