Liver organoids: modelling complexity in homeostasis and disease

open access: yesFEBS Letters, EarlyView.
Studying liver in vitro has been challenging because simple 2D cell cultures fail to capture liver's cellular and architectural complexity. To bridge this gap, scientists increasingly use organoids, 3D liver models which better mimic liver composition and function. This review examines recent advances in liver organoid complexity and realism, discusses

Temporal properties of cerebellar-dependent memory consolidation [PDF]

open access: yes, 2004
Classical conditioning of the nictitating membrane response in rabbits is a well defined model of cerebellar-dependent motor memory. This memory undergoes a period of consolidation after the training session, when it is sensitive to reversible ...

Classical conditioning in social robots

open access: yes, 2014
© Springer International Publishing Switzerland 2014. Classical conditioning is important in humans to learn and predict events in terms of associations between stimuli and to produce responses based on these associations.

Epigenetic reprogramming of lineage switching in cancer

open access: yesFEBS 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

Teaching and demonstrating classical conditioning

open access: yes, 1989
Problems relating to classroom demonstrations of classical conditioning, especially tendencies to misrepresent Pavlov\u27s procedures, are discussed.

The psychophysiology of posttraumatic stress disorder and panic disorder : fear conditioning, autonomous underpinnings and issues of measurement [PDF]

open access: yes, 2007
Die Ergründung des Phänomens Angst in seinen gesunden und pathologischen Ausprägungen stellt für Forscher und Kliniker auch nach Jahrzehnten intensiver Forschung immer noch eine Herausforderung dar. Angst ist eine adaptive und verhaltenssteuernde Emotion,

In the Blink of an Eye: Investigating the Role of Awareness  in Fear Responding by Measuring the Latency of  Startle Potentiation

open access: yesBrain Sciences, 2012
The latency of startle reflex potentiation may shed light on the aware and unaware processes underlying associative learning, especially associative fear learning.

The microbiome in human skin aging

open access: yesFEBS Letters, EarlyView.
Age‐related skin changes encompass the well‐known visible phenotypic alterations, together with microbiome dysbiosis and a series of molecular aging hallmarks. These hallmarks characterize not only a fully stablished aged phenotype but also the skin aging process itself.

Golgi enzymes are retrieved from the plasma membrane to the trans‐Golgi network

open access: yesFEBS Letters, EarlyView.
Golgi enzymes are traditionally considered resident proteins retained within the Golgi apparatus. Here, we demonstrate that a subset transiently reaches the cell surface and is subsequently retrieved to the trans‐Golgi network via retrograde transport. Using a nanobody‐based toolkit, we uncover a dynamic trafficking cycle of several Golgi enzymes.

Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry

open access: yesFEBS 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 ...
