introduction: cryptorchidism has been proved to cause apoptosis in germ cells in respond to changes in the stimulation levels of specific physiological events. the purpose of this study was to determine whether treatment of bilateral cryptorchidism was associated with alterations in testicular gene expression. methods: to induce bilateral cryptorchid model, immature mice were anesthetized and a...
Bcl-2 has been shown to inhibit apoptosis induced by several anticancer agents and to cause a dissociation between etoposide (VP-lot-induced protein-cross-linked DNA strand breaks and VP-16-induced cell death. We suggested previously that VP-16-induced cytotoxicity is mediated by a series of events leading from cleavable complex formation to aberrant UNA recombination, as measured by sister chr...
Among the many target genes of the transcription factor NF-kappaB are p53 and c-myc, both of which are involved in apoptosis. This prompted us to investigate the role of NF-kappaB in this process. We report that NF-kappaB is potently activated upon serum starvation, a condition leading to apoptosis in 293 cells. Similar to Bcl-2, a transdominant-negative mutant of the NF-kappaB p65 subunit part...
Using a rat model of moderate hypothermic (26 degrees C-28 degrees C) cardiopulmonary bypass (CPB) with hemodilution, we investigated hippocampal apoptotic gene expression and neuronal apoptosis up to 6 h after CPB. The CPB was performed on male rats (380-400 g) under general anesthesia with isoflurane and fentanyl. The right atrium and tail artery were cannulated, and a peristaltic pump and me...
BACKGROUND AND PURPOSE We showed previously that Bcl-2 overexpression with the use of herpes simplex viral (HSV) vectors improved striatal neuron survival when delivered 1.5 hours after stroke but not when delivered 5 hours after stroke onset. Here we determine whether hypothermia prolongs the therapeutic window for gene therapy. METHODS Rats were subjected to focal ischemia for 1 hour. Hypot...
Objective(s): The increasing rate of over using cell phones has been considerable in youths and pregnant women. We examined the effect of mobile phones radiation on genes expression variation on cerebellum of BALB/c mice before and after of the birth. Materials and Methods: In this study, amobile phone jammer, which is an instrument to prevent receiving signals between cellular phonesand base t...
The t(11;14)(q13;q32) translocation and its molecular counterpart bcl-1 rearrangement are frequently associated with mantle cell lymphomas (MCLs) and only occasionally with other variants of B-cell lymphoid malignancies. This translocation seems to activate the expression of PRAD-1/cyclin D1 gene located downstream from the major breakpoint cluster region of this rearrangement. However, the pos...
BACKGROUND Flow cytometric immunophenotyping (FCI), is widely used in cytology for distinguishing between B-cell lymphoma (BCL) and reactive lymphocytic proliferations (RLP), mainly by identifying monotypic B-cell populations. Since this cannot always be determined by ratios of surface immunoglobulin light chains (sIg LCs) we wanted to assess if cytoplasmic immunoglobulin (cIg) LCs, Bcl-2 and p...
OBJECTIVE We recently reported that doxorubicin (Dox), an effective anti-cancer drug, induces apoptosis in cardiac myocytes in association with reduction of Bcl-xl expression. In the present study, we further examined whether overexpression of Bcl-xl ameliorates Dox-induced cardiac myocyte damage. METHODS AND RESULTS Overexpression of the Bcl-xl gene by adenovirus vector resulted in an 11-fol...
conclusions in general, it seems that three-month exercise training was effective in reducing cardiac mitochondrial pro-apoptotic protein. however, considering the results of the bcl2 gene expression, more researches are needed to identify effects of exercise trainings on indices of myocardial apoptosis. objectives the aim of this study was to assess the effect of exercise training on bcl-2 and...
