objective: curcumin, is the active component in turmeric (curcuma long). this agent induces apoptosis via inhibiting various signaling pathways. however, its poor aqueous solubility prevents its widespread application. in this study, dendrosomes with water-solubility, nano-sized dimensions and nontoxic properties, was used for curcumin delivery to cells. materials & methods: in the present...

BACKGROUND Bax is a strong pro-apoptotic gene that induces programmed cell death when expressed. Human telomerase reverse transcriptase (hTERT) is the catalytic subunit for telomerase, an enzyme found to be active in more than 85% of human cancers. Recently, a binary adenoviral system (Ad/GT-Bax + Ad/hTERT-GV16) was constructed using the hTERT promoter to induce Bax gene expression in tumor cel...

Introduction: Cancer can be defined as an illness of reformed gene expression. There are numerous agents affecting expression and altering cellular activities. Nanotechnology has offered the possibility modulating tumor suppressor genes’ expression, improving kinetics gene-targeted therapeutics, simplifying drug delivery to tumors across bio-complexes.Methods: Gene expressions caspase3, 8 9, Ba...

Background: Bax and Bcl-2 are the major members of Bcl-2 family whose play a key role in tumor progression or inhibition of intrinsic apoptotic pathway triggered by mitochondrial dysfunction. Therefore, the balance between pro- and anti-apoptotic members of this family can determine the cellular fate. Methods: In this study, the relative level of mRNA expression of Bax and Bcl-2 genes was deter...

The bax gene promoter region contains four motifs with homology to consensus p53-binding sites. In cotransfection assays using p53-deficient tumor cell lines, wild-type but not mutant p53 expression plasmids transactivated a reporter gene plasmid that utilized the bax gene promoter to drive transcription of chloramphenicol acetyltransferase. In addition, wild-type p53 transactivated reporter ge...
