Comprehensibility of UML-based Formal Model – A Series of Controlled Experiments

open access: yes, 2007
This paper summarises two controlled experiments conducted on a model that integrates the use of semi-formal notation, the Unified Modelling Language (UML) and a formal notation, B.

Oxygen‐independent expression of HIF‐1α during the cell cycle in hepatocellular carcinoma cells controls essential metabolic pathways under normoxia

open access: yesThe FEBS Journal, EarlyView.
In Huh7 cells, HIF‐1α is essential as it maintains the expression of proteins involved in glycolysis and steroid/cholesterol biosynthesis both under normoxia and hypoxia. On the other hand, in HeLa cells, these pathways are induced by HIF‐1α only under hypoxia.

Cellular Morphometric Analysis (CellMorph)—a comprehensive imaging‐based tool for quantifying cellular phenotype heterogeneity and dynamics across biological processes

open access: yesThe FEBS Journal, EarlyView.
CellMorph is a groundbreaking tool that allows researchers to analyze multiple features from single cells, including cell size and shape, cytosolic staining and subcellular texture, nuclear staining, and morphometry. By evaluating images from both bright‐field and fluorescence microscopy, it also tracks changes in living cells during key processes such

Limited roles of the miR‐17‐92 cluster in the regulation of T‐cell apoptosis

open access: yesThe FEBS Journal, EarlyView.
The pro‐apoptotic protein BIM shapes T‐cell survival and function, but how it is regulated remains unclear. In a mouse model lacking direct miR‐17‐92:Bim interactions, we observed a moderate reduction in Th17 CD4+ T cells. BIM levels were modestly increased in double‐positive thymocytes and naive CD8+ T cells, but this did not affect overall T‐cell ...

Phycocyanobilin biosynthesis in Galdieria sulphuraria requires isomerization of phycoerythrobilin synthesized by bilin reductases

open access: yesThe FEBS Journal, EarlyView.
The biosynthesis of bilins, tetrapyrroles essential for light harvesting and sensing, is performed by specific enzymes (FDBRs). In Galdieria sulphuraria, both phycobiliprotein types bind phycocyanobilin, despite lacking the canonical synthesizing gene PCYA. Instead, PEBA and PEBB are encoded, producing phycoerythrobilin, proposed to be later isomerized

Regulation of PHOX2B gene expression by the long non‐coding natural antisense RNA PHOX2B‐AS1

open access: yesThe FEBS Journal, EarlyView.
PHOX2B is a transcription factor essential for autonomic nervous system development. We identify and characterize PHOX2B‐AS1, a human long non‐coding antisense transcript at the PHOX2B locus, along with its murine counterpart. Our findings reveal bidirectional transcription and reciprocal regulation: PHOX2B activates PHOX2B‐AS1, whereas PHOX2B‐AS1 ...

Extracellular vesicles released from melanoma cells constitutively expressing MHC class II promote immune evasion and cancer progression

open access: yesThe FEBS Journal, EarlyView.
Here, we report the role of extracellular vesicles (EVs) released from melanoma cells constitutively expressing MHC class II in the regulation of immune cell functions and melanoma metastasis. In particular, we observed an increased localization of HLA‐DRα, CAM receptors, PD‐L1, and STAT3 signaling proteins in the EVs.

Selective targeting of cortactin tandem repeat acetylation by human lysine deacetylases

open access: yesThe FEBS Journal, EarlyView.
Cortactin function is regulated by acetylation at several lysine residues within its tandem repeat region. Using genetic code expansion to generate cortactin variants containing precisely defined acetylation marks, we show that HDAC6 is the primary enzyme removing these modifications, with SIRT1 and SIRT2 also acting at selected sites but with lower ...

The competitive interplay of 12‐oxophytodienoic acid (OPDA), protein thiols, and glutathione

open access: yesThe FEBS Journal, EarlyView.
12‐Oxophytodienoic acid (OPDA) is a phytohormone involved in plant growth and stress defense. Due to its cyclopentenone moiety, OPDA can form Michael adducts with thiol‐containing compounds such as glutathione and cysteine residues of proteins, resulting in alterations of the cellular redox regulatory network.
