Evolution of proteinase inhibitor diversity in leguminous plants of tropical rainforests is under immense pressure from the regular upregulation of proteolytic machinery of their pests. The present study illustrates the isolation and bioinsecticidal potency of a serine proteinase inhibitor from the seeds of Caesalpinia bonduc (CbTI), inhabiting Great(More)
Recently, the role of cadmium (Cd) in immunosupression has gained importance. Nevertheless, the signaling pathways underlying cadmium-induced immune cell death remains largely unclear. In accordance to our previous in vivo report, and to evaluate the further details of the mechanism, we have investigated the effects of cadmium (CdCl(2), H(2)O) on cell cycle(More)
Cadmium is one of the inflammation-related xenobiotics and has been regarded as a potent carcinogen. The relationship between inflammation and cell proliferation due to chronic infection has been studied, but the mechanism is not fully clear. Though the mode of cadmium toxicity is well characterized in animal cells, still it requires some further(More)
Summary Plasmodium vivax depends on interaction with the Duffy antigen/receptor for chemokines (DARC) for invasion of human erythrocytes. The 140 kDa P. vivax Duffy-binding protein (PvDBP) mediates interaction with DARC. The receptor-binding domain of PvDBP maps to its N-terminal, cysteine-rich region, region II (PvRII), which contains approximately 300(More)
Exposure to cadmium is associated with the development of pulmonary damage such as emphysema and lung cancer. This metal is also a powerful inducer of different proinflammatory and cell cycle regulatory proteins in many biologic models. Previously, we showed that prolonged exposure of low concentration of cadmium resulted in upregulation of proinflammatory(More)
Leguminous plants in the tropical rainforests are a rich source of proteinase inhibitors and this work illustrates isolation of a serine proteinase inhibitor from the seeds of Archidendron ellipticum (AeTI), inhabiting Great Nicobar Island, India. AeTI was purified to homogeneity by acetone and ammonium sulfate fractionation, and ion exchange, size(More)
An investigation of the molecular mechanism of the anticancer activity demonstrated by the ruthenium(II)–arene compound [Ru(η6-p-cymene)Cl2(pta)] (pta is 1,3,5-triaza-7-phosphaadamantane), termed “RAPTA-C”, in Ehrlich ascites carcinoma (EAC) bearing mice is described. RAPTA-C exhibits effective cell growth inhibition by triggering G2/M phase arrest and(More)
Cadmium is the major component of polluted environment which can be fatal by mechanisms that are not fully clear. Our study indicates immunosupression may be one of the reason for that. It is well known that cadmium (Cd) has toxic and carcinogenic effects in rhondents and humans, but the effects of cadmium on apoptosis are still not clear. Although some(More)
We investigated the expression of –CXC chemokine ligand 13 (CXCL13) and its receptor –CXC chemokine receptor 5 (CXCR5) in 98 breast cancer (BC) patients with infiltrating duct carcinoma, out of which 56 were found lymph node metastasis (LNM) positive. Interestingly, co-expression of CXCL13 and CXCR5 showed a significant correlation with LNM. Since,(More)
Copper is an essential trace element for human physiological processes. To evaluate the potential adverse health impact/immunotoxicological effects of this metal in situ due to over exposure, Swiss albino mice were treated (via intraperitoneal injections) with copper (II) chloride (copper chloride) at doses of 0, 5, or 7.5 mg copper chloride/kg body weight(More)
