Terpinolene (TPO) is a natural monoterpene present in essential oils of many aromatic plant species. Although various biological activities of TPO have been demonstrated, its neurotoxicity has never been explored. In this in vitro study we investigated TPO's antiproliferative and/or cytotoxic properties using the 3-(4,5-dimethylthiazol-2-yl)-2,5 diphenyltetrazolium bromide (MTT) test, genotoxic...
background: the rh antigens are expressed as parts of a protein complex in the rbc membrane. this complex is a tetramer, consisting of two molecules of rhag and two molecules of rh proteins. to express rhd in rbc membrane, expression of rhag is essential. this co-expression only occurs in the erythroid lineage. k562 cell line has an erythroid lineage. materials and methods: cord blood was used ...
Neuroglobin, a vertebrate oxygen-binding protein, is expressed in many regions of the adult brain. We examined the cell type-specific expression of neuroglobin in neurons and astroglial cells in primary cultures of fetal hippocampal cells and sections of the adult mouse brain using neuroglobin-specific polyclonal antibodies and cell type-specific markers NeuN and GFAP to differentiate between n...
Aquatic microbes produce diverse secondary metabolites with interesting biological activities. Cytotoxic metabolites have the potential to become lead compounds or drugs for cancer treatment. Many cytotoxic compounds, however, show undesirable toxicity at higher concentrations. Such undesirable activity may be reduced or eliminated by using lower doses of the cytotoxic compound in combination w...
Accumulating evidence suggests that long non-coding RNAs (lncRNAs) are playing critical roles in neurogenesis, yet the underlying molecular mechanisms remain largely elusive. Neurite outgrowth is an early step in neuronal differentiation and regeneration. Using in vitro differentiation of neuroblastoma-derived Neuro-2a (N2a) cell as a model, we performed expression profiling to identify lncRNAs...
one of the major complications in cancer chemotherapy is the development of resistance, and cisplatin, as one of the important medicines in treatment regimens of different cancers is not excluded. one of the most described cellular defense mechanisms involved in resistance is glutathione (gsh) and in this study, the effects of cisplatin on the total intracellular gsh level (gshi) in some sensit...
Epigenetic modifications, particularly histone acetylation, have been implicated in Alzheimer's disease (AD). While previous studies have suggested that histone hypoacetylation may regulate the expression of genes associated with memory and learning in AD, little is known about histone regulation of AD-related genes such as Presenilin 1(PS1) and beta-site amyloid precursor protein cleaving enzy...
Tumor vaccines have held much promise, but to date have demonstrated little clinical success. This lack of success is conceivably due to poor tumor antigen presentation combined with immuno-suppressive mechanisms exploited by the tumor itself. Knock down of Inhibitor of differentiation protein 2 (Id2-kd) in mouse neuroblastoma whole tumor cells rendered these cells immunogenic. Id2-kd neuroblas...
objective(s): development of molecules that specifically recognize cancer cells is one of the major areas in cancer research. human epidermal growth factor receptor 2 (her2) is specifically expressed on the surface of breast cancer cells. her2 is associated with an aggressive phenotype and poor prognosis. in this study we aimed to isolate rna aptamers that specifically bind to her2 overexpressi...
the influenza viruses are major etiologic agents of human respiratory infections, and inflict a sizable health and economic burden. this study examines the antiinfluenza virus activity of hydroalcoholic extract of olive leaves (olhe). olive leaves were collected from gardens around the city of shiraz, characterized, dried, ground to powder, and its hydroalcoholic extract was prepared. the influ...
