Here, we describe a methodology to perform a targeted siRNA “ubiquitome” screen to identify novel ubiquitin and ubiquitin-like regulators of the HIF1A-mediated cellular response to hypoxia. This can be adapted to any biological pathway where a robust read out of reporter activity is available.

Traits, Mood, and Subjective Wellbeing

Subjective well-being (SWB) refers to an individual's self-evaluation of their overall life satisfaction, happiness, and fulfillment. This multifaceted construct is typically assessed by analyzing the balance of positive and negative emotions alongside perceptions of life satisfaction. Personality traits such as neuroticism and extraversion are strongly associated with variations in SWB, offering critical insights into the underlying mechanisms of emotional well-being. Neuroticism and Emotional...

GTPases and their Regulation

2020
Guanine nucleotide-binding proteins (G-proteins), also known as GTPases, are a superfamily of proteins that regulate many cellular processes, such as cell signaling, vesicular transport, and the regulation of cell shape and motility. Mutation or dysfunction of these proteins can lead to disease. There are around 40,000 known G-proteins that can broadly be classified into two groups ‒ small G-proteins consisting of a single domain and large multi-domain G-proteins. Large G-proteins, also known...

MALT1 regulates innate immunity but how this occurs remains ill-defined. We used the selective MALT1 paracaspase inhibitor MLT-827 to unravel the contribution of MALT1 to innate signaling downstream of Toll-like or C-type lectin-like receptors, demonstrating that MALT1 regulates the production of myeloid cytokines, and downstream of C-type lectin-like receptors, selectively.

We present a protocol that allows investigation of the neural correlates of deliberate and automatic emotion regulation, using functional magnetic resonance imaging. This protocol can be used in healthy participants, both young and older, as well as in clinical patients.
FAQs
Feedback processes help adjust neuronal activity as emotional conditions change, rather than producing a fixed response. By linking current activity with subsequent signaling, these processes can moderate affective reactions and support adaptation to internal or environmental conditions. Their importance becomes especially clear when researchers examine how mood responses persist, shift, or become dysregulated over time.
Neurotransmitters and hormones provide chemical signals that coordinate activity across the systems involved in mood. Their effects interact with neural communication and feedback processes, allowing emotional state, motivation, and responses to conditions to change together. Studying this coordination helps researchers distinguish alterations in chemical signaling from broader disruptions in circuit function.
Stress, reward, and social experiences can modify neuronal activity and affective responses through their effects on interconnected circuits and signaling systems. These influences provide distinct ways to study how environmental events shape mood and behavior. Comparing them can reveal whether a change reflects altered responses to conditions, disrupted feedback, or broader circuit-level dysregulation.
Physiological changes can modify the internal conditions that mood regulation pathways must respond to, producing corresponding changes in affective state or behavior. Including these changes in neuroscience research helps connect bodily signals with neural and chemical processes. This broader view is relevant when explaining why mood may vary even without a clearly identified environmental trigger.
Researchers can examine coordinated changes in neural circuits, neurotransmitter and hormone signaling, neuronal activity, feedback processes, and behavioral responses. They can also compare effects associated with stress, reward, social experience, or physiological change. Together, these observations help identify relationships between pathway function and mood-related outcomes without reducing the explanation to a single brain region or signal.
Research can connect symptoms and behavioral changes with disrupted circuit function or chemical signaling in mood regulation pathways. This framework supports the search for biomarkers, which are measurable indicators of biological state, and informs treatments designed to target affected circuits or signaling systems. The same approach also helps compare mechanisms across depression, anxiety, bipolar disorder, and related conditions.
