Znovjyak K, Seredyuk M, Malinkin SO, Golenya IO, Amirkhanov VM, Shova S, Mulloev NU. Znovjyak K, et al. Acta Crystallogr E Crystallogr Commun. 2021 Apr 30;77(Pt 5):573-578. doi: 10.1107/S2056989021004412. eCollection 2021 May 1. Acta Crystallogr E Crystallogr Commun. 2021. PMID: 34026268 Free PMC article.
In the crystal, neighbouring mol-ecules are linked through weak C-HC/S/N inter-actions into a three-dimensional network. The inter-mol-ecular contacts were qu-anti-fied using Hirshfeld surface analysis and two-dimensional fingerprint plots, revealing the relative contribut …

Analysis of Expression Pattern of snoRNAs in Human Cells A549 Infected by Influenza A Virus.
Zhuravlev E, Sergeeva M, Malanin S, Amirkhanov R, Semenov D, Grigoryeva T, Komissarov A, Stepanov G. Zhuravlev E, et al. Int J Mol Sci. 2022 Nov 8;23(22):13666. doi: 10.3390/ijms232213666. Int J Mol Sci. 2022. PMID: 36430145 Free PMC article.
We identified 66 that were upregulated and 55 that were downregulated in response to influenza A virus infection. The increased expression of most C/D-box snoRNAs was associated with elevated levels of 5'- and 3'-short RNAs derived from this snoRNA. ...Furthermore, influen …

Receptor-mediated internalization of chelator-PNA-peptide hybridization probes for radioimaging or magnetic resonance imaging of oncogene mRNAs in tumours.
Tian X, Chakrabarti A, Amirkhanov N, Aruva MR, Zhang K, Cardi CA, Lai S, Thakur ML, Wickstrom E. Tian X, et al. Biochem Soc Trans. 2007 Feb;35(Pt 1):72-6. doi: 10.1042/BST0350072. Biochem Soc Trans. 2007. PMID: 17233604
We observed that human MCF7 breast cancer cells that overexpress IGF1R efficiently internalized fluorescein-chelator-PNA-D(Cys-Ser-Lys-Cys) to the cytoplasm, but not with D(Cys-Ala-Ala-Cys). Scintigraphic imaging of MCF7 xenografts in immunocompromised mice revealed …

Antisense oligonuclotides with oxetane-constrained cytidine enhance heteroduplex stability, and elicit satisfactory RNase H response as well as showing improved resistance to both exo and endonucleases.
Pradeepkumar PI, Amirkhanov NV, Chattopadhyaya J. Pradeepkumar PI, et al. Org Biomol Chem. 2003 Jan 7;1(1):81-92. doi: 10.1039/b210163g. Org Biomol Chem. 2003. PMID: 12929393
Antisense oligonucleotides (AONs) with single and double oxetane C modifications [1',2'-oxetane constrained cytidine, 1-(1',3'-O-anhydro-beta-D-psicofuranosyl)cytosine] have been evaluated, in comparison with the corresponding T-modified AONs, for their antisense potential …
