To explore the molecular pathways underlying thiazolidinediones effects on pancreatic islets in conditions mimicking normo- and hyperglycemia, apoptosis rate and transcriptional response to Pioglitazone at both physiological and supraphysiological glucose concentrations were evaluated. Adult rat islets were cultured at physiological (5.6 mM) and supraphysiological (23 mM) glucose concentrations...

This study assessed the apoptotic process occurring in the hemocytes of the Pacific oyster, Crassostrea gigas, exposed to Alexandrium catenella, a paralytic shellfish toxins (PSTs) producer. Oysters were experimentally exposed during 48 h to the toxic algae. PSTs accumulation, the expression of 12 key apoptotic-related genes, as well as the variation of the number of hemocytes in apoptosis was ...

BACKGROUND Alterations of the p53 (also called TP53) gene are one of the most common abnormalities in gliomas. We have previously reported that restoration of wild-type p53 protein function in glioma cells results in programmed cell death (apoptosis). Since p53 functions are mediated by genes that directly control the tumor suppressor effect of the p53 protein, understanding the relationship be...

Objective: Autophagy is necessary for the progression of psoriasis. This study aimed to recognize possible autophagy-related genes in psoriasis via bioinformatics present a better standard clinical treatment and management Methods: The GEO dataset was utilized derive mRNA expression profile database GSE78097. R software find autophagy-associated that may be expressed Then, Protein-protein inter...

Aging can be defined as a decline of physiological function that is more difficult to reverse, characterized by the loss integrity tissues, organs, and cells an organism over time. Normal aging associated with structural functional changes in brain, involving neuronal apoptosis, synaptic structure, neurotransmission, metabolism alterations, leading impairment sleep, cognitive functions, memory,...

objective(s): glioblastoma multiforme (gbm) is one of the most lethal forms of human cancer and temozolomide (tmz) is currently part of the standard treatment for this disease. combination therapy using natural substances can enhance the anti-cancer activity of tmz. the purpose of this study was to evaluate the effect of tmz in combination with thymoquinone (tq) on human gbm cell line (u87mg). ...
