A simple and sensitive assay for rapid detection of human coronavirus NL63 (HCoV-NL63) was developed by colorimetic reverse transcription loop-mediated isothermal amplification (RT-LAMP). The method employed six specially designed primers that recognized eight distinct regions of the HCoV-NL63 nucleocapsid protein gene for amplification of target sequences under isothermal conditions at 63 degrees C for 1 h Amplification of RT-LAMP was monitored by addition of calcein before amplification. A positive reaction was confirmed by change from light-brown to yellow-green under visual detection. Specificity of the RT-LAMP assay was validated by cross-reaction with different human coronaviruses, norovirus, influenza A virus, and influenza B virus. Sensitivity was evaluated by serial dilution of HCoV-NL63 RNA from 1.6 x 10(9) to 1.6 x 10(1) per reaction. The RT-LAMP assay could achieve 1,600 RNA copies per reaction with high specificity. Hence, our colorimetric RT-LAMP assay could be used for rapid detection of human coronavirus NL63.

Objective:To investigate the effect of blocking the expression of receptor activity modifying protein 1 (RAMP1 )on calcito-nin gene-related peptide(CGRP)-induced MG-63 cell proliferation.Methods:RAMP1 siRNA was synthesized and screened by tran-scription in vitro.The subcultured MG-63 cells were divided into the following groups:RAMP1 siRNA interference group,empty vector group and blank control group.The mRNA expression and the membrane distribution changes of the calcitonin receptor-like receptor (CRLR)and the receptor component protein (RCP)in MG-63 cells were examined by real-time PCR and immunofluorescence method respectively.Results:RAMP1 and CRLR mRNA and the fluorescence intensity of MG-63 cells decreased after transfection by RAMP1 siRNA(P <0.05).In RAMP1 interference group,the expression of RCP mRNA and the fluorescence intensity were higher than those in the other two groups(P <0.05).After RAMP1 siRNA interference,the proliferation of MG-63 cells was inhibited(P <0.05). Conclusion:RAMP1 siRNA transfection may reduce CRLR expression and inhibite the proliferation of MG-63 cell.

Objective: To detect the expression of miR-373 in osteosarcoma cells and explore its effects on cell proliferation, invasion, and migration. Methods: Human osteosarcoma cell line SJSA-1 and human osteoblast hFOB 1.19 cultured in vitro. Human osteosarcoma cell line SJSA-1 were randomly divided into four groups: blank control group (CK group), negative control group (NC group), miR-373 over-expressed plasmid group (miR-373 mimic group) and miR-373 inhibited plasmid group (miR-373 inhibitor group). Cells were transfected with FuGENE^® HD transfection reagent. After 48 hours of transfection, the relative expression of miR-373 was detected by quantitative real-time polymerase chain reaction (qRT-PCR), cell proliferation by cell counting kit-8 (CCK-8) and cell invasion and migration by Transwell. Results: The relative expression of miR-373 in SJSA-1 cells was significantly higher than that in hFOB-1.19 cells (P<0.05); compared with CK group and NC group, the relative expression of miR-373 in the miR-373 mimic group increased significantly (P<0.05), and the relative expression of miR-373 in the miR-373 inhibitor group was significantly lower than that in the control group (P<0.05); optical density (OD) value of miR-373 mimic group at 24 h, 36 h, and 48 h were significantly higher than that of CK group and NC group (P<0.05), and OD value of miR-373 inhibitor group at 24 h, 36 h, and 48 h were significantly lower than that of CK group and NC group (P<0.05); the number of cell migration in the miR-373 mimic group was significantly higher than that in the CK group and NC group (P<0.05), and the number of cell migration in the miR-373 inhibitor group was significantly lower than that in CK group and NC group (P<0.05); the number of cell migration in the miR-373 mimic group was significantly higher than that in the CK group and NC group (P<0.05), and the number of cell migration in the miR-373 inhibitor group was significantly lower than that in CK group and NC group (P<0.05). Conclusions The expression of miR-373 is up-regulated in osteosarcoma. Overexpression of miR-373 can promote the proliferation, invasion, and migration of osteosarcoma cells, while the low expression of miR-373 can inhibit the proliferation, invasion, and migration of osteosarcoma cells, which may be an important target for the diagnosis and treatment of osteosarcoma.

Background: s/Aims: Transmembrane 6 superfamily member 2 (TM6SF2) E167K variant is closely associated with the occurrence and development of metabolic dysfunction-associated steatotic liver disease (MASLD). However, the role and mechanism of TM6SF2 E167K variant during MASLD progression are not yet fully understood. Methods: The Tm6sf2167K knock-in (KI) mice were subjected to high-fat diet (HFD). Hepatic lipid levels of Tm6sf2167K KI mice were detected by lipidomics analysis. Thin-layer chromatography (TLC) was used to measure the newly synthesized triglyceride (TG) and phosphatidylcholine (PC). Results: The TM6SF2 E167K variant significantly aggravated hepatic steatosis and injury in HFD-induced mice. Decreased polyunsaturated PC level and increased polyunsaturated TG level were found in liver tissue of HFDinduced Tm6sf2167K KI mice. Mechanistic studies demonstrated that the TM6SF2 E167K variant increased the interaction between TM6SF2 and PNPLA3, and impaired PNPLA3-mediated transfer of polyunsaturated fatty acids (PUFAs) from TG to PC. The TM6SF2 E167K variant increased the level of fatty acid-induced malondialdehyde and reactive oxygen species, and decreased fatty acid-downregulated cell membrane fluidity. Additionally, the TM6SF2 E167K variant decreased the level of hepatic PC containing C18:3, and dietary supplementation of PC containing C18:3 significantly attenuated the TM6SF2 E167K-induced hepatic steatosis and injury in HFD-fed mice. Conclusions The TM6SF2 E167K variant could promote its interaction with PNPLA3 and inhibit PNPLA3-mediated transfer of PUFAs from TG to PC, resulting in the hepatic steatosis and injury during MASLD progression. PC containing C18:3 could act as a potential therapeutic supplement for MASLD patients carrying the TM6SF2 E167K variant.

The Coronaviridae family is characterized by a nucleocapsid that is composed of the genome RNA molecule in combination with the nucleoprotein (N protein) within a virion. The most striking physiochemical feature of the N protein of SARS-CoV is that it is a typical basic protein with a high predicted pI and high hydrophilicity, which is consistent with its function of binding to the ribophosphate backbone of the RNA molecule. The predicted high extent of phosphorylation of the N protein on multiple candidate phosphorylation sites demonstrates that it would be related to important functions, such as RNA-binding and localization to the nucleolus of host cells. Subsequent study shows that there is an SR-rich region in the N protein and this region might be involved in the protein-protein interaction. The abundant antigenic sites predicted in the N protein, as well as experimental evidence with synthesized polypeptides, indicate that the N protein is one of the major antigens of the SARS-CoV. Compared with other viral structural proteins, the low variation rate of the N protein with regards to its size suggests its importance to the survival of the virus.
