N-myristoyltransferase (NMT) exists in two isoforms, NMT1 and NMT2, that catalyze myristoylation of various proteins crucial in signal transduction, cellular transformation, and oncogenesis. We have recently demonstrated that NMT1 is essential for the early development of mouse embryo. In this report, we have demonstrated that an invariant consequence of(More)
It was been previously reported that thyalpha1 can be used to activate monocytes, BMDM and TAM. However, the effect of thyalpha1 on other tissue macrophages has not been investigated. Moreover, there is no report about the use of thyalpha1-treated macrophages in adoptive immunotherapy of cancer. In view of these observations in the present study, we checked(More)
We have previously suggested that thymosin alpha(1) (thyalpha1), an immunomodulating thymic hormone, can activate tumor-associated macrophages to a tumoricidal state in a murine model bearing a transplantable T-cell lymphoma of spontaneous origin designated as Dalton's lymphoma (DL). Since tumor-infiltrating dendritic cells (DC) also play an important role(More)
Previously we have demonstrated that in-vivo growth of a murine T-cell lymphoma of spontaneous origin designated as Dalton's lymphoma (DL) shows sex dimorphism (J Rep Immunol 2005; 65:17-32). It remained unclear, however, if DL growth in female and male tumor-bearing hosts also shows a sex-dependent differential susceptibility to the antitumor action of(More)
The present study explores the potential of the anti-neoplastic action of aspirin in a transplantable murine tumour model of a spontaneously originated T-cell lymphoma designated as Dalton's lymphoma. The antitumour action of aspirin administered to tumour-bearing mice through oral and/or intraperitoneal (intratumoral) routes was measured via estimation of(More)
The present investigation was undertaken to study if a gender-dependent differential induction of tumor cell apoptosis is responsible for the manifestation of gender dimorphism observed in the growth of a transplantable murine T cell lymphoma, designated as Dalton's lymphoma (DL). Tumor cell samples obtained from male tumor-bearing mice showed a higher(More)
BACKGROUND Orlistat, a fatty acid synthase (FASN) inhibitor, has been demonstrated to inhibit tumor cell survival. However, the mechanism(s) of its tumor growth retarding action against malignancies of hematological origin remains unclear. It is also not understood if the antitumor action of orlistat implicates modulated susceptibility of tumor cell to(More)
Using a murine model of a T cell lymphoma, in the present study, we report that tumor growth retarding action of curcumin involves modulation of some crucial parameters of tumor microenvironment regulating tumor progression. Curcumin-administration to tumor-bearing host caused an altered pH regulation in tumor cells associated with alteration in expression(More)
A number of previous investigations have reported that physical exercise renders immunopotentiating and antitumor therapeutic benefits to the tumor-bearing host. As these effects of physical exercise are mainly mediated through the modulation of hormonal and cytokine repertoire, it remains unclear if male and female tumor-bearing hosts show a(More)
Proton pump inhibitors (PPI) are being considered for antineoplastic therapeutic regimens due to their ability to reverse H(+) homeostasis in tumor microenvironment and induce tumor cell death. In order to explore additional mechanism(s) underlying antitumor action of PPI, the present investigation was undertaken to investigate the effect of a PPI(More)
