Abstract Background Phytochemicals and plant extracts are showing promising anticancer potentials. In the current study, volatile faction (essential oil) of Nigella sativa seeds was evaluated against some hepatocellular carcinoma (HCC). The essential oil extracted characterized by chromatographic techniques to reveal its chemical composition, especially thymoquinone. Then, fabricated in two nan...

Introduction: Although the initial hypothesis for the action of doxepin was based on the inhibition of the reuptake of neurotransmitters, it has been suggested that it may also involve other mechanisms. Therefore, this study aims to investigate the effect of doxepin on spatial memory, tumor necrosis factor alpha (TNF-&alpha) level, expression of pro-apoptotic (Bad and Bax) and anti-apoptotic (B...

background: nowadays, oocytes and embryos vitrification has become a routine technique. based on clinical judgment, re-vitrification maybe required. but little is known about re-vitrification impact on genes expression. objective: the impact of re-vitrification on apoptotic and implanting genes, bax, bcl-2 and erbb4, at compaction stage embryos were evaluated in this study. materials and method...

The effect of p53 gene therapy on chemosensitivity and apoptotic response of PANC-1 tumor cells, which express high amount of mutant p53, to cancer chemotherapeutic agents of Etoposide and Doxorubicin was investigated. Comparison of the chemosensitivity of PANC-1 cells to its wild type p53 transfectants showed that wt-p53 expressing transfectants are more sensitive to both Etoposide and Doxorub...

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...

Despite numerous studies examining the possible induction of apoptosis in porcine reproductive and respiratory syndrome virus (PRRSV)-infected cells, it remains unclear if PRRSV infection results in direct apoptotic induction. There is clear evidence that apoptotic cells are present in tissues from PRRSV-infected pigs. However, many of these studies have failed to show that the apoptotic cells ...

Transforming growth factor (TGF)-β exhibits both pro-apoptotic and anti-apoptotic effects on epithelial cells in a context-dependent manner. The anti-apoptotic function of TGF-β is mediated by several downstream regulatory mechanisms, and has been implicated in the tumor-progressive phenotype of breast cancer cells. We conducted RNA sequencing of mouse mammary gland epithelial (NMuMG) cells and...
