Context: To establish a novel approach for quick and high throughput verification of human gene imprinting.', "By use of a pair of dye-labeled probes, 5' nuclease assay was combined with reverse transcriptase-PCR(RT-PCR) to genotype a coding single nucleotide polymorphism (cSNP), rs705(C/T) of a known imprinted gene, small nuclear ribonucleotide protein N (SNRPN), on both genomic DNA and cDNA of human lymphoblast cell lines.", 'Allele discrimination showed a clear monoallelic expression pattern of SNRPN, which was confirmed by RT-PCR based restriction fragment length polymorphisms. Pedigree analysis verified the paternal origin of expressed allele, which is in consistency with previous report.
Answer: Coding SNP is an ideal marker for detecting gene imprinting by 5' nuclease assay. This approach has also a potentiality to discover differential allele expression of non-imprinted genes in order to find gene cis-acting functional polymorphism.

Ex Output:
Is [ Coding single nucleotide polymorphism an ideal marker for detecting gene imprinting by 5 ' nuclease assay ]?

Context: The interaction between Siglec-10 and its ligand, CD24, selectively represses tissue damage-caused immune responses. However, the nature of Siglec-10 and CD24 in human hepatocellular carcinoma (HCC) is still poorly defined. Hereon, the expression, function, and regulation of CD24 and Siglec-10 in HCC were investigated in the present study.', 'Flow cytometry was performed to examine the expression of Siglec-10 in HCC tissues and adjacent non-tumor tissues of HCC patients. To further determine whether Siglec-10 expression is associated with the clinical characteristics and survival, conventional immunohistochemistry was performed in 96 HCC patients. Additionally, the role of Siglec-10 in the regulation of natural killer (NK) cell dysfunction was evaluated. Finally, CD24 expression in HCC was also assessed.', 'Siglec-10 was expressed most on NK cells in HCC (40.7 4.5%). Compared with surrounding non-tumor tissues, tumor tissues had higher Siglec-10 expression (31.0 1.7% versus 40.7 4.5%, n = 10, P < 0.05), and the expression was negatively associated with patient survival. Siglec-10(+)CD56(+) NK cells exhibited reduced effector function, as shown by decreased granules and cytokine expressions compared with Siglec-10(-)CD56(+) NK cells. Moreover, the number of CD24(+)CD45(-) cells in HCC tissues was higher than that in adjacent non-tumor tissues (9.4 0.9% versus 3.1 0.9%, n = 15, P < 0.05).
Answer: These findings suggest that Siglec-10 is associated with decreased survival and impaired NK cell function in human HCC. This process may function via the CD24-Siglec-10 interaction, which may represent a therapeutic target in HCC patients.

Is siglec-10 associated with survival and natural killer cell dysfunction in hepatocellular carcinoma?

Context: The ubiquitin proteasome system (UPS) mediates regulated protein degradation and provides a mechanism for closely controlling protein abundance in spatially restricted domains within cells. We hypothesized that the UPS may acutely determine the local concentration of key regulatory proteins at neuronal synapses as a means for locally modulating synaptic efficacy and the strength of neurotransmission communication.', 'We investigated this hypothesis at the Drosophila neuromuscular synapse by using an array of genetic and pharmacological tools. This study demonstrates that UPS components are present in presynaptic boutons and that the UPS functions locally in the presynaptic compartment to rapidly eliminate a conditional transgenic reporter of proteasome activity. We assayed a panel of synaptic proteins to determine whether the UPS acutely regulates the local abundance of native synaptic targets. Both acute pharmacological inhibition of the proteasome (<1 hr) and targeted genetic perturbation of proteasome function in the presynaptic neuron cause the specific accumulation of the essential synaptic vesicle-priming protein DUNC-13. Most importantly, acute pharmacological inhibition of the proteasome (<1 hr) causes a rapid strengthening of neurotransmission (an approximately 50% increase in evoked amplitude) because of increased presynaptic efficacy. The proteasome-dependent regulation of presynaptic protein abundance, both of the exogenous reporter and native DUNC-13, and the modulation of presynaptic neurotransmitter release occur on an intermediate, rapid (tens of minutes) timescale.
Answer: Taken together, these studies demonstrate that the UPS functions locally within synaptic boutons to acutely control levels of presynaptic protein and that the rate of UPS-dependent protein degradation is a primary determinant of neurotransmission strength.

Does the ubiquitin proteasome system acutely regulate presynaptic protein turnover and synaptic efficacy?
