Epigenetic reprogramming of lineage switching in cancer
FEBS Letters, EarlyView.Cancer cells rarely commit to a single identity. Epigenetic mechanisms and tumor microenvironment cues push epithelial cells toward flexible, hybrid states that can shift into mesenchymal, neuroendocrine, or stem‐like fates, driving metastasis, drug resistance, and tumor heterogeneity. Targeting the epigenetic regulators behind these transitions, using

Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry
FEBS Letters, EarlyView.EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...

Another Look at Emergent Evolutionism
, 1965 The doctrine of emergent evolutionism has been before the philosophical world for over fifty years, but there are several reasons why another look at it may be opportune.

Emerging experimental and computational methods for studying redox‐regulated structural transitions
FEBS Letters, EarlyView.Redox reactions can reshape proteins and alter how they behave in cells, with important consequences for health and disease. This review explores emerging experimental and computational approaches for discovering these redox‐sensitive protein switches, revealing their structural effects, and predicting their behavior, opening new opportunities to ...

Anti-Evolutionism and the Effects of the Scopes Trial [PDF]
, 1982 In 1925 John T. Scopes was convicted of the crime of teaching evolution in violation of a new Tennessee law. The circus-like trial has been regarded by many observers as a rite de passage for twentieth century attitudes-although Scopes was convicted, his

FEBS Letters, EarlyView.Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

Dušan Bandić – context, opus, significance
Etnoantropološki Problemi, 2014 The scientific opus of Dušan Bandić is viewed through the context and time frame in which he started researching folk religion in order to, through the analysis of his most important texts, arrive at the conclusion about the importance of his opus for ...

‘Guide and Prejudice’— How Argonautes recognize targets across domains of life
FEBS Letters, EarlyView.Argonaute proteins use short nucleic‐acid guides to locate and regulate specific targets across all domains of life. Despite striking diversity—from human gene silencing to bacterial immune defence—all Argonautes share a conserved three‐stage recognition logic: guide‐directed sampling, progressive target pairing with a conformational checkpoint and ...

Structural and biochemical analysis of a B12 superbinder
FEBS Letters, EarlyView.BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.

СВІТ ЯК ДІЄРОЗВІЙ (uβrιζ) АБО УНІВЕРСАЛЬНО-ІСТОРИЧНИЙ ЕВОЛЮЦІОНІЗМ (World as the actdevelopment (uβrιζ) or universal-historical evolutionism ) [PDF]
, 2013 За сучасними науково-філософськими уявленнями світ не є даність, а є його творення як розвиток, що зумовлює креаціоністський еволюціонізм.
