Abstract
This paper reports a smart intracellular nanocarrier for sustainable and controlled drug release in non-invasive neuroregeneration. The nanocarrier is composed by superparamagnetic iron oxide-gold (SPIO-Au) core-shell nanoparticles (NPs) conjugated with porous coordination cages (PCCs) through the thiol-containing molecules as bridges. The negatively charged PCC-2 and positively charged PCC-3 are compared for intracellular targeting. Both types result in intracellular targeting via direct penetration across cellular membranes. However, the pyrene (Py)-PEG-SH bridge enabled functionalization of SPIO-Au NPs with PCC-3 exhibits higher interaction with PC-12 neuron-like cells, compared with the rhodamine B (RhB)-PEG-SH bridge enabled case and the stand-alone SPIO-Au NPs. With neglectable toxicities to PC-12 cells, the proposed SPIO-Au-RhB(Py)-PCC-2(3) nanocarriers exhibit effective drug loading capacity of retinoic acid (RA) at 13.505 μg/mg of RA/NPs within 24 h. A controlled release of RA is achieved by using a low-intensity 525 nm LED light (100% compared to 40% for control group within 96 h).

Purinergic Receptor Expression and Potential Association with Human Embryonic Stem Cell-Derived Oligodendrocyte Progenitor Cell Development. CELL JOURNAL 2017; 19:386-402.

Abstract
Objective Due to recent progress in production of human embryonic stem cell-derived oligodendrocyte progenitor cells (hESC-OPCs) for ameliorating myelin disease
such as multiple sclerosis (MS) and the role of purinergic signaling in OPCs development, we avaluated the profile of purinergic receptors expression during development
of OPCs from hESC. Materials and Methods In this experimental study, we used reverse transcription and
quantitative polymerase chain reaction (RT-qPCR) to obtain more information about
potential roles of purinergic receptors during in vitro production of hESC-OPCs. We
first determined the expression level of different subtypes of purinergic receptors in
hESCs, embryoid bodies (EBs), and hESC-OPCs. The effects of A1adenosine receptor (A1AR)
activation on hESC-OPCs development were subsequently examined. Results hESCs and OPCs had different mRNA expression levels of the AR subtypes.
ARs mRNA were expressed in the EB stage, except for A2AAR. We observed expressions
of several P2X (P2X1, 2, 3, 4, 5, 7) and P2Y (P2Y1, 2, 4, 6, 11-14) genes in hESCs. hESC-OPCs
expressed different subtypes of P2X (P2X1, 2, 3,4,5,7) and P2Y (P2Y1, 2, 4, 6, 11-14). Except for P2X1
and P2X6, all other P2X and P2Y purinergic receptor subtypes expressed in EBs. We also
indicate that A1AR might be involved in modulating gene expression levels of cell cycle
regulators in an agonist and/or dose-dependent manner.
Conclusion Elucidation of the expression pattern of purinergic receptors and the effects
of different subtypes of these receptors in hESC-OPCs may have a promising role in future cell-based therapy or drug design for demyelinating disease.

Abstract
Receptors for extracellular nucleotides are widely expressed by mammalian cells. They mediate a large array of responses ranging from growth stimulation to apoptosis, from chemotaxis to cell differentiation and from nociception to cytokine release, as well as neurotransmission. Pharma industry is involved in the development and clinical testing of drugs selectively targeting the different P1 nucleoside and P2 nucleotide receptor subtypes. As described in detail in the present review, P2 receptors are expressed by all tumours, in some cases to a very high level. Activation or inhibition of selected P2 receptor subtypes brings about cancer cell death or growth inhibition. The field has been largely neglected by current research in oncology, yet the evidence presented in this review, most of which is based on in vitro studies, although with a limited amount from in vivo experiments and human studies, warrants further efforts to explore the therapeutic potential of purinoceptor targeting in cancer.

Abstract
Extracellular purines and pyrimidines have emerged as key regulators of a wide range of physiological and pathophysiological cellular processes acting through P1 and P2 cell surface receptors. Increasing evidence suggests that purinergic receptors can interact with and/or modulate the activity of other classes of receptors and ion channels. This review will focus on the interactions of purinergic receptors with other GPCRs, ion channels, receptor tyrosine kinases, and steroid hormone receptors. Also, the signal transduction pathways regulated by these complexes and their new functional properties are discussed.

Abstract
Pheochromocytomas are tumors originating from chromaffin cells of the adrenal medulla, which have been observed in numerous carcinogenicity studies. The authors have evaluated pheochromocytoma concurrence with other effects and the possible mechanisms, in order to assess the relevance of such data for the classification of carcinogenic effects and their relevance to humans. The evaluation revealed that pheochromocytomas occur with relatively higher frequency in male rats, especially when the following conditions are involved: hypoxia, uncoupling of oxidative phosphorylation, disturbance in calcium homeostasis, and disturbance of the hypothalamic endocrine axis. The underlying biochemical mechanisms suggest that other substances that interfere with these biochemical endpoints also produce pheochromocytomas. Such endpoints include enzymes involved in catecholamine synthesis, receptor tyrosine kinase (RET), hypoxia-inducible factor (HIF), succinate dehydrogenase, fumarate hydratase, and pyruvate dehydrogenase. To date, there is no indication that the substances inducing pheochromocytomas in animal experiments also induce corresponding tumors in humans. Because the mechanisms of action identified in rats are to be expected in humans, pheochromocytomas may be induced after exposure conditions similar to those used in the animal studies. Whether hereditary mutations represent a risk factor in humans is not clear. Pheochromocytomas that occur in animal experiments currently appear to have little relevance for conditions at the work place. When sufficiently documented and evaluated, such secondary pheochromocytomas are not relevant for classification and human risk assessment.

Abstract
Apoptosis is a major mechanism for cell death in the nervous system during development. P2X(7) nucleotide receptors are ionotropic ATP receptors that mediate cell death under pathological conditions. We developed an in vitro protocol to investigate the expression and functional responses of P2X(7) nucleotide receptors during retinoic acid (RA)-induced neuronal differentiation of human SH-SY5Y neuroblastoma cells. Neuronal differentiation was examined measuring cellular growth arrest and neuritic processes elongation. We found that SH-SY5Y cells treated for 5 days with RA under low serum content exhibited a neuron-like phenotype with neurites extending more than twice the length of the cell body and cell growth arrest. Concurrently, we detected the abolishment of intracellular-free calcium mobilization and the down-regulation of P2X(7) nucleotide receptor protein expression that protected differentiated cells from neuronal cell death and reduced caspase-3 cleavage-induced by P2X(7) nucleotide receptor agonist. The role of P2X(7) nucleotide receptors in neuronal death was established by selectively antagonizing the receptor with KN-62 prior to its activation. We assessed the involvement of protein kinases and found that p38 signaling was activated in undifferentiated after nucleotide stimulation, but abolished by the differentiating RA pretreatment. Importantly, P2X(7) receptor-induced caspase-3 cleavage was blocked by the p38 protein kinase specific inhibitor PD169316. Taken together, our results suggest that RA treatment of human SH-SY5Y cells leads to decreased P2X(7) nucleotide receptor protein expression thus protecting differentiated cells from extracellular nucleotide-induced neuronal death, and p38 signaling pathway is critically involved in this protection of RA-differentiated cells.

Abstract
Subtelomeric imbalances have been implicated in developmental delay and mental retardation (MR) and described for most chromosomes. This study reports the first detailed description of two individuals with de novo 12q subtelomere deletions and high-resolution mapping of their deletion size with oligonucleotide array CGH for genotype/phenotype comparisons. Patient 1 is an 8-year-old male with borderline mild MR, food-seeking behavior, obesity, no significant dysmorphic facial features, abnormal hair whorl pattern, brachydactyly and mild clinodactyly. Patient 2 is a 12-year-old male with mild MR, food-seeking behavior, obesity, short stature, mild dysmorphic facial features, multicystic kidney and unilateral cryptorchidism. Both patients share a deleted region of approximately 1.6 Mb, including 14 known genes, which perhaps contributed to their similar phenotypes. However, Patient 2 has more severe MR and organ system involvement, possibly due to the larger deletion size ( approximately 4.5 Mb) including an additional eight genes, although it is difficult to make phenotype/genotype correlations based on only two patients. Due to the relatively mild presentation of both of our patients, we propose that a proportion of individuals with subtelomeric imbalances may go undetected and therefore, recommend subtelomeric studies be carried out for cases of unexplained mild MR or isolated learning disability (LD) with behavioral problems in the absence of major dysmorphic features or birth defects. In addition, 12q subtelomeric deletions should be considered in the differential diagnosis of patients presenting with food-seeking behavior and resultant obesity, as well as those referred to rule out Prader-Willi syndrome.
