FEBS Open Bio, EarlyView.Amino acids sequence of two different proteins with the same sequence (chameleon sequence—black boxes) represent in 3D structure of the proteins different secondary structures: HHHH—helical and BBB—Beta‐structural. The chains folded in water environment adopt different III‐order structures in which the chameleon fragments appear to adopt similar status

Almost complex and almost contact structures in fibred Riemannian spaces
Hiroshima Mathematical Journal, 1988 Relations among structures of fibre spaces [cf. e.g. \textit{S. Ishihara} and \textit{M. Konishi}, Differential geometry of fibred spaces (Tokyo 1973; Zbl 0337.53001)] with almost Hermitian or almost contact metric structures and those of base spaces and fibres are studied.

FEBS Open Bio, EarlyView.ERα splice variant ERα∆7 lacks the C‐terminus, and its expression may change phenotypes of breast cancers. Our results showed that ERα∆7 is found in the luminal A subtype, and elevated ERα∆7 levels are linked to improved cell survival with lower proliferation and migration.

Admissible para-hyper-Kähler structures on distributions of almost contact metric manifolds
Дифференциальная геометрия многообразий фигур, 2018 The concepts of an admissible (almost) para-hyper-Kähler structure are introduced. On distribution of an almost contact metric manifold, as on the total space of a vector bundle, an admissible almost para-hypercomplex structure is defined.

FEBS Open Bio, EarlyView.Bisphenol A (BPA), a common chemical in plastics, exerts dual effects on bladder cancer cells: low doses promote growth and migration, while high doses suppress growth and migration. Multi‐omics and bioinformatics reveal BPA acts via MAPK and inflammatory pathways.

Two theorems on (ϵ)-Sasakian manifolds
International Journal of Mathematics and Mathematical Sciences, 1998 In this paper, We prove that every (ϵ)-sasakian manifold is a hypersurface of an indefinite kaehlerian manifold, and give a necessary and sufficient condition for a Riemannian manifold to be an (ϵ)-sasakian manifold.

Evolutionarily divergent DUF4465 domains have a common vitamin B12‐binding function
FEBS Open Bio, EarlyView.We show that DUF4465 family proteins, widespread across bacteria from gut microbiomes, hydrothermal vents, and soil, share a common vitamin B12‐binding function. These augmented β‐jellyroll proteins bind vitamin B12 via extended loops. Our findings establish sequence‐diverse DUF4465 proteins as a widespread class of B12‐binding proteins, highlighting ...

Intercompartmental communication in senescence
FEBS Open Bio, EarlyView.Senescent cells experience structural changes in the plasma membrane, endoplasmic reticulum, mitochondria, lysosomes, nucleus, and cytoskeleton. These alterations disrupt crosstalk among cellular compartments, impairing vesicular trafficking, contact sites, and molecular flow.

On some almost contact metric hypersurfaces of W4-manifolds
Дифференциальная геометрия многообразий фигур, 2018 It is proved that 3-hypersurfaces of W4-manifolds admit an almost contact metric structures that can be identical to the structure induced on 2-hypersurfaces of such manifolds.
