1. Duplexes Formed by G4C2 Repeats Contain Alternate Slow- and Fast-Flipping G·G Base Pairs
Arijit Maity, Fernaldo Richtia Winnerdy, Gang Chen, Anh Tuân Phan Biochemistry. 2021 Apr 13;60(14):1097-1107. doi: 10.1021/acs.biochem.0c00916. Epub 2021 Mar 22.
Aberrant expansion of the hexanucleotide GGGGCC (or G4C2) repeat in the human C9ORF72 gene is the most common genetic factor found behind amyotrophic lateral sclerosis and frontotemporal dementia. The hypothesized pathways, through which the repeat expansions contribute to the pathology, involve one or more secondary structural forms of the DNA and/or RNA sequences, such as G-quadruplexes, duplexes, and hairpins. Here, we study the structures of DNA and RNA duplexes formed by G4C2 repeats, which contain G(syn)·G(anti) base pairs flanked by either G·C or C·G base pairs. We show that duplexes formed by G4C2 repeats contain alternately two types of G·G pair contexts exhibiting different syn-anti base flipping dynamics (~100 ms vs ~2 ms for DNA and ~50 ms vs ~20 ms for RNA at 10 °C, respectively) depending on the flanking bases, with the slow-flipping G·G pairs being flanked by a guanine at the 5'-end and the fast-flipping G·G pairs being flanked by a cytosine at the 5'-end. Our findings on the structures and dynamics of G·G base pairs in DNA and RNA duplexes formed by G4C2 repeats provide a foundation for further studies of the functions and targeting of such biologically relevant motifs.
2. Association between Interleukin-17F 7488A/G and 7383A/G polymorphisms and susceptibility to juvenile idiopathic arthritis
Eman Rateb Abd Almonaem, Ashraf Mohamed Shaheen, Amira M N Abdelrahman, Waleed A Hassan, Noha Mohamed Daay El Khair, Omima Mohamed Abdel Haie Pediatr Res. 2022 Sep 6. doi: 10.1038/s41390-022-02288-1. Online ahead of print.
Background: Interleukin-17F (IL-17F), one of the cytokines, is crucial in the pathophysiology of juvenile idiopathic arthritis (JIA). Therefore, we aimed to determine the relation between IL17F 7488A/G and IL17F 7383A/G single-nucleotide polymorphisms and JIA susceptibility and to explain their impact on the disease activity. Methods: Genomic DNA of 70 patients with JIA and 70 age and sex-matched controls were extracted and typed for IL17F 7488A/G and IL17F 7383A/G single-nucleotide polymorphisms, using polymerase chain reaction with sequence-specific primers method, and compared between patients and controls. Results: When compared to AA participants, children with the AG genotype of the IL17F 7488A/G and IL17F 7383A/G polymorphisms showed a substantially greater risk of JIA. Furthermore, children with the G allele were 2.8 folds more likely to have JIA than the A allele for IL17F 7488A/G polymorphism and 3.72 folds for IL17F 7383A/G polymorphism. Children with AG genotype of IL17F 7383A/G polymorphism were far more likely to have high activity JIA. Conclusions: The G allele of both IL17F 7488A/G and IL17F7383 A/G polymorphisms is associated with increased JIA susceptibility, and JIA at High Disease Activity was more likely to develop in AG subjects of the IL17F 7383 A/G polymorphism. Impact: The relationship between Interleukin-17F 7488A/G and 7383A/G polymorphisms and risk for JIA has not been recognized before. Impact of Interleukin-17F 7488A/G and 7383A/G genotypes on JIA disease activity. The G allele of both IL17F 7488A/G and IL17F7383 A/G polymorphisms are associated with increased JIA susceptibility. AG genotype of Interleukin-17F 7383 A/G polymorphism compared to AA patients, had a higher probability of developing JIA at a High Disease Activity (HDA) level.
3. Structural comparison of unconventional G protein YchF with heterotrimeric G protein and small G protein
Maozhen Luo, Zhiwei Han, Guoye Huang, Rongfang Li, Yi Liu, Junjie Lu, Lin Liu, Rui Miao Plant Signal Behav. 2022 Dec 31;17(1):2024405. doi: 10.1080/15592324.2021.2024405. Epub 2022 Feb 8.
Guanine nucleotide-binding (G) proteins, namely, phosphate-binding (P) loop GTPases, play a critical role in life processes among different species. Based on the structural characteristics, G proteins can be divided into heterotrimeric G proteins, small G proteins and multiple unique unconventional G proteins. The highly conserved unconventional G protein YchF is composed of a core G domain, an inserted coiled-coil domain, and a TGS domain from the N-terminus to the C-terminus. In this review, we compared the structural characteristics of the G domain in rice OsYchF1 with those of Rattus norvegicus heterotrimeric G protein α-subunit and human small G protein Ras-related G protein C and analyzed the binding modes of these G proteins with GTP or ATP by performing molecular dynamics simulations. In summary, it will provide new insights into the enormous diversity of biological function of G proteins.
