Neuronal responses to extracellular matrix (ECM) constituents are likely to play an important role in nervous system development and regeneration. We have studied the interactions of a neuron-like rat pheochromocytoma cell line, PC12, with ECM protein-coated substrates. Using a quantitative cell attachment assay, PC12 cells were shown to adhere readily to laminin (LN) or collagen IV (Col IV) bu...
Recently use of endosulfan has aroused a great concern among clinical and basic neuroscientists as besides adult population even the children residing in some areas of touristic state of Kerala, India which are under constant spraying of endosulfan had shown symptoms of CNS dysfunctioning including cerebral palsy, retardation of mental and physical growth, epilepsy and various congenital anomal...
A novel method of neural differentiation of PC12 cells by using Opti-MEM as a basic induction medium
The PC12 cell line is a classical neuronal cell model due to its ability to acquire the sympathetic neurons features when deal with nerve growth factor (NGF). In the present study, the authors used a variety of different methods to induce PC12 cells, such as Opti-MEM medium containing different concentrations of fetal bovine serum (FBS) and horse serum compared with RPMI-1640 medium, and then o...
The growth of PC12 cells on a collagen substratum or on monolayers of several non-neuronal cell types was studied by measuring nerve growth factor (NGF)-dependent increases in the expression of a 150 X 10(3) (Mr) neurofilament protein subunit and the membrane glycoprotein Thy-1. Both responses were found to be greatly suppressed in cultures of fibroblasts as compared to the C2 and G8-1 muscle c...
Exosomes deliver functional proteins and genetic materials to neighboring cells, and have potential applications for tissue regeneration. One possible mechanism of exosome-promoted tissue regeneration is through the delivery of microRNA (miRNA). In this study, we hypothesized that exosomes derived from neuronal progenitor cells contain miRNAs that promote neuronal differentiation. We treated me...
OBJECTIVES This study was designed to indicate whether different fractions from Artemisia biennis hydroethanolic extract could provide cytoprotection against oxidative stress and apoptosis induced by doxorubicin (DOX) in rat pheochromocytoma cell line (PC12). MATERIAL AND METHODS Cell viability was determined by MTT assay. Also, activation of caspase-3 and superoxide dismutase were evaluated ...
Doxorubicin (DOX) is a potent, broad-spectrum chemotherapeutic drug used for treatment of several types of cancers. Despite its effectiveness, it has a wide range of toxic side effects, many of which most likely result from its inherent prooxidant activity. It has been reported that DOX has toxic effects on normal tissues, including brain tissue. In the current study, we investigated the protec...
Cysteine string protein (Csp) is essential for neurotransmitter release in Drosophila. It has been suggested that Csp functions by regulating the activity of presynaptic Ca2+ channels, thus controlling exocytosis. We have examined the effect of overexpressing Csp1 in PC12 cells, a neuroendocrine cell line. PC12 cell clones overexpressing Csp1 did not show any changes in morphology, granule numb...
Plasma membrane Ca(+2)-ATPase (PMCA), encoded by four separate genes, constitutes a high affinity system extruding Ca(+2) outside the cell. The nerve growth factor-treated PC12 cell line possesses all four main PMCA isoforms. To evaluate the potential role of PMCA isoforms in the differentiation process, we transiently suppressed the expression of PMCA2 and 3 using the antisense oligonucleotide...
BACKGROUND Alzheimer's disease (AD) is one of the common neurodegenerative disorders among elderly. The purpose of this study was to determine the neuroprotective effect and mechanisms of action underlying the Terminalia chebula extracts and ellagic acid by using beta-amyloid25-35 (Aβ25-35)-induced cell toxicity in an undifferentiated pheochromocytoma (PC12) cell line. MATERIALS AND METHODS T...
