microRNAs in avian influenza virus H9N2-infected and non-infected chicken embryo fibroblasts

X. Peng, Gao, Q. S., Zhou, L., Chen, Z. H., Lu, S., Huang, H. J., Zhan, C. Y., and Xiang, M., microRNAs in avian influenza virus H9N2-infected and non-infected chicken embryo fibroblasts, vol. 14, pp. 9081-9091, 2015.

There is limited information about microRNAs (miR­NAs) in H9N2 subtype influenza virus-infected chicken cells or tissues. In this study, 10,487,469 and 13,119,795 reads were obtained from in­fected and non-infected chicken embryo fibroblasts, respectively. Seven hundred and thirty-six and 1004 miRNAs, including mature miRNAs and precursors, were obtained from the infected and non-infected fibro­blasts, respectively.

PCR-RFLP genotyping protocol for chicken Mx gene G/A polymorphism associated with the S631N mutation

L. Sironi, Ramelli, P., Williams, J. L., and Mariani, P., PCR-RFLP genotyping protocol for chicken Mx gene G/A polymorphism associated with the S631N mutation, vol. 9, pp. 1104-1108, 2010.

The Mx (myxovirus resistance) gene codes for a protein with antiviral activity. Non-synonymous G/A polymorphism at position 2032 of chicken Mx cDNA results in a change at amino acid 631 of the Mx protein. This mutation has been shown to affect the antiviral activity of the Mx molecule, although recent studies have not confirmed this effect in response to some influenza strains. Nevertheless, the G/A polymorphism could be important for the chicken’s response to other viruses.
