in many acute leukemias, normal differentiation does not occur. however, in many cell lines derived from hematologic malignancies, differentiation or programmed cell death (apoptosis) can be induced by variety of agents including: vitamin analogs, demethylating agents, cyclic amp analogs and anti-proliferative agents. to the best of our knowledge there has been not any study specifically to ana...

Background and Objective: Sensory neurons have critical role in improvement of functional outcome of any neuroprotective strategy. The herbal medicine Nepeta menthoides has been reported to have anti-apoptotic effect on axotomized spinal motoneurons. In the present study, the putative neuroprotective effect of Nepeta menthoides on the axotomized dorsal root ganglion sensory neurons in neonate r...

HIGHLIGHTS Chondrocytes express PAR-4 in the nucleus and cytoplasm; Vitamin D reduces pro-apoptotic proteins caspase-3; caspase-3 may be potential therapeutic targets for osteoarthritis.

in this review we summarize the current knowledge on the mechanisms by which the pore-forming bcl-2 family members bax and bak are activated on the mitochondrial outer membrane (mom) in apoptotic cells. we compare the two major working models and conclude that they are both insufficient to explain reality. instead, we need to identify novel binding partners and posttranslational modifications o...

Effects of progesterone and estradiol on the inflammatory apoptotic markers ovariectomized rats challenged with acute septic systemic inflammationSinan Subhi Farhan, Samir Saad Mahgoub, Abdulrahman Hussain

A number of studies have provided evidence that cell death from moderate traumatic spinal cord injury (SCI) is regulated, in part, by apoptosis that involves the caspase family of cysteine proteases. However, little or no information is available about anti-apoptotic mechanisms mediated by the inhibitors of apoptosis (IAP) family of proteins that inhibit cell death pathways. In the present stud...

Mitochondria, play an important role in a variety of processes including energy production, apoptosis, autophagy and inflammation. Caspases, are proteases that play an essential role in mediating apoptotic process of programmed cell death. An association between mitochondria and caspases is very well defined during apoptosis. Besides apoptosis, emerging data is strongly suggesting a direct asso...

Exosomes are released by various cells, including natural killer (NK) cells and transport signaling molecules for the intercellular communication. Hepatocellular carcinoma (HCC), also known as primary liver cancer, is often inoperable difficult to accurate diagnosis. Notably, prognosis underlying mechanisms of HCC not fully understood. Exosomes-derived NK (NK-exos) express unique cytotoxic prot...
