we have previously shown that the proliferative response of t cells to antigenic or mitogenic stimulus decreased with age and that caloric resection (cr) attenuated the age-related decline in proliferation and il-2 expression. because activation-induced apoptosis is known to regulate cell proliferation and eliminate the high number of activated cells during an immune response, it was of interes...

In the current work, a new set of carbohydrazide linked benzofuran-isatin conjugates (5a–e and 7a–i) was designed synthesised. The anticancer activity for compounds (5b–d, 7a, 7b, 7d 7g) measured against NCI-55 human cancer cell lines. Compound 5d most efficient, thus subjected to five-dose screen where it showed excellent broad almost all tested subpanels. Furthermore, good anti-proliferative ...

Spinal cord injury (SCI) is the major cause of severe disability worldwide, which leads to neuron death, neuronal degeneration, and functional changes in spinal cord. Eucommia ulmoides extract (EUE) composed multiple iridoids phenols possesses anti-oxidative anti-inflammatory effects various pathologies. This study aims evaluate EUE on SCI underlying mechanisms. Male adult Sprague-Dawley rats (...

Objective(s): In this study, we aimed to investigate the effects of anti-Fas ribozyme on the apoptosis of T lymphocytes (T cells) in mice model with chronic obstructive pulmonary disease (COPD). Materials and Methods: Male 6-week-old C57BL/6 mice were used to establish the COPD model by exposure to cigarette smoke. The COPD mice were sacrificed for spleen dissection and T cell isolation. T cell...

introduction : arsenic trioxide (as2o3) causes antitumor effects by various mechanisms, including degradation of pml-rara in the acute promyelocytic cells, growth inhibition and induction of apoptosis. however, the precise mechanisms of these processes remain incompletely understood. the purpose of this study was to evaluate the effects of arsenic trioxide on cell growth, cell cycle regulation ...

Apoptosis is the natural programmed cell death process, which responsible for abnormal clearance. However, many cancer cells develop various mechanisms to escape apoptosis through interrupting apoptosome assembly, a key step initiate apoptosis. This promotes tumorigenesis and drug resistance, thus, poses great challenge in treatment. Herein, biomimetic lipid nanocarrier mimicking mitochondrial ...

objective(s) doxorubicin (dox), a widely used chemotherapeutic agent can give rise to serve cardiotoxicity by inducing apoptosis. curcumin, the active compound of the rhizome of curcuma longa l. has anti-inflammatory, antioxidant and anti-proliferative activities. curcumin has been identified to increase cytotoxicity in several cancer cell lines in combination with dox, but there is no study ab...

Objective(s): Breast cancer is a devastating disease related to women. The anticancer properties of 8-hydroxyquinoline (8HQ) and the increasing use of graphene oxide (GO), as a drug delivery system with anti-cancerous properties, led us to investigate the toxicity and apoptosis-induction capability of 8HQ-coated GO on breast cancer cells compared with normal breast cel...

By linking surface Ig to the FcR Fc gamma RII on the mouse B lymphocyte surface, whole anti-Ig has been shown to block cell cycle entry and subsequent Ab production, a phenomenon called the "Fc receptor off-signal." IL-4 or blocking Ab to Fc gamma RII, present with whole anti-Ig, restores cell cycle progress to the levels observed with F(ab')2 anti-Ig. The current study demonstrates that under ...
