FEBS Open Bio, EarlyView.Hyperosmotic stress triggers the relocation of the CFIm complex from the nucleus to the cytoplasm. This shift creates a nuclear ‘stoichiometric bottleneck’, limiting CFIm availability for mRNA processing. Consequently, specific mRNAs like NUDT21 and DICER1 undergo targeted 3′UTR shortening, demonstrating how spatial protein dynamics drive rapid ...

FEBS Open Bio, EarlyView.IGFBP4 knockdown (KD) impairs preadipocyte proliferation and is associated with IGF1R protein downregulation and attenuated AKT phosphorylation. The mechanisms by which IGFBP4 KD influences the IGF1R/AKT signaling pathway involve newly synthesized proteins and lysosomal degradation pathways. Created in BioRender.

Positive periodic solutions for a predator-prey model with time delays and impulsive effect
Electronic Journal of Differential Equations, 2008 In this article, a two-species predator-prey model with time delays and impulsive effect is investigated. By using Mawhin's continuation theorem of coincidence degree theory, sufficient conditions are obtained for the existence of positive periodic ...

Protocol for quantifying miRNA trafficking across the endosomal membrane
FEBS Open Bio, EarlyView.An in vitro protocol measures miRNA uptake into endosomes isolated from mammalian cell extracts, which are free of subcellular contaminants. Performed at 37 °C in the presence of ATP, it ensures the import of single‐stranded miRNA into the endosomal lumen.

Strongly stable algorithm for computing periodic system zeros [PDF]
, 2003 We propose a computationally efficient and numerically reliable algorithm to compute the finite zeros of a linear discrete-time periodic system. The zeros are defined in terms of the transfer-function matrix corresponding to an equivalent lifted time ...

FEBS Open Bio, EarlyView.Glioblastoma cells express calcitonin receptor variants (CT receptor isoforms) that may help them survive stress. Using qPCR, transcript‐specific long‐read nanopore sequencing, immunofluorescence co‐localisation and comparative sequence analysis, this study identifies a novel alternatively spliced CALCR transcript that encodes the CTb receptor isoform ...

Square-Root Balancing and Computation of Minimal Realizations of Periodic Systems [PDF]
, 1998 We propose a numerically reliable approach for balancing and minimal realization of linear periodic systems with time-varying dimensions. The proposed approach to balancing belongs to the family of square-root methods with guaranteed enhanced ...
