Abundance, diversity, and depth distribution of planctomycetes in acidic northern wetlands.

Frontiers in microbiology

Ivanova AO, Dedysh SN.
PMID: 22279446

Single crystalline iron sulfide nanoparticles doped with chromium Fe1-xCrxS (0 ≤x≤ 0.15) have been successfully prepared by a thermal decomposition method. The particles are self-organized into the single crystalline plates with the accurate hexagonal shape and dimensions up to...

Arl13b regulates Shh signaling from both inside and outside the cilium.

Molecular biology of the cell

Mariani LE, Bijlsma MF, Ivanova AA, Suciu SK, Kahn RA, Caspary T.
PMID: 27682584
Mol Biol Cell. 2016 Sep 28; doi: 10.1091/mbc.E16-03-0189. Epub 2016 Sep 28.

The regulatory GTPase Arl13b localizes to primary cilia, where it regulates Sonic hedgehog (Shh) signaling. Missense mutations in ARL13B can cause the ciliopathy Joubert syndrome, while the mouse null allele is embryonic lethal. We used mouse embryonic fibroblasts as...

Comparative Study on the MDR Reversal Effects of Selected Chalcones.

International journal of medicinal chemistry

Ivanova AB, Batovska DI, Todorova IT, Stamboliyska BA, Serly J, Molnar J.
PMID: 27516904
Int J Med Chem. 2011;2011:530780. doi: 10.1155/2011/530780. Epub 2010 Dec 29.

Based on the structure of three previously established lead compounds, fifteen selected chalcones were synthesized and evaluated for their multidrug resistance (MDR) reversal activity on mouse lymphoma cells. The most active chalcones were stronger revertants than the positive control,...

Comparative Genomics of Four Isosphaeraceae Planctomycetes: A Common Pool of Plasmids and Glycoside Hydrolase Genes Shared by .
