Synaptically Localized Transcriptional Regulators in Memory Formation [PDF]

Neuroscience, 2018
At the neuronal cell level, long-term memory formation emerges from interactions between initial activity-dependent molecular changes at the synapse and subsequent regulation of gene transcription in the nucleus. This in turn leads to strengthening of the connections back at the synapse that received the initial signal.

Tumor B‐cell infiltration in platinum‐treated advanced muscle‐invasive urothelial carcinoma

Molecular Oncology, EarlyView.
Bladder tumors with higher pretreatment memory B‐cell infiltration were linked to longer survival after cisplatin chemotherapy, but not carboplatin. These tumors also showed more organized immune structures (tertiary lymphoid structures) and a shared pro‐inflammatory B‐cell‐rich community, suggesting that memory B cells may help identify patients most ...

Phosphorylation of Npas4 by MAPK Regulates Reward-Related Gene Expression and Behaviors

Cell Reports, 2019
Summary: Dopamine (DA) activates mitogen-activated protein kinase (MAPK) via protein kinase A (PKA)/Rap1 in medium spiny neurons (MSNs) expressing the dopamine D1 receptor (D1R) in the nucleus accumbens (NAc), thereby regulating reward-related behavior ...

Transcription: A Mechanism for Short-Term Memory [PDF]

Current Biology, 2008
Yeast growing for a considerable time in glucose 'remember' a previous exposure to galactose, the inducer of its galactose-utilization (GAL) genes. This memory is conveyed by a cytoplasmically transmitted galactokinase working as a signal transducer.

Epigenetic heterogeneity and plasticity in therapy‐induced tumor states through single‐cell multi‐omics

Molecular Oncology, EarlyView.
Single‐cell multi‐omics reveals epigenetic heterogeneity across therapy‐adaptive tumor states, including quiescent/dormant, drug‐tolerant persister, and EMT‐like phenotypes. By linking regulatory features with state‐associated biomarkers, these approaches inform biomarker‐guided therapeutic strategies for evolving tumors.

The Transcriptional Regulation of Memory

, 2016
The formation of various forms of memory involves a series of distinct cellular and molecular mechanisms, many of which are not fully understood. There are highly conserved pathways that are involved in learning, memory, and synaptic plasticity, which is the primary substrate for memory storage.

Acute Heat Priming Dampens Gene Expression Response to Thermal Stress in a Widespread Acropora Coral

Ecology and Evolution
Physiological plasticity is fundamental for resisting environmental change. As climate change accelerates and environmental stressors become more frequent, understanding how habitat‐forming species shift their physiology to match their environment is ...

H2A.Z-mediated localization of genes at the nuclear periphery confers epigenetic memory of previous transcriptional state. [PDF]

PLoS Biology, 2007
Many genes are recruited to the nuclear periphery upon transcriptional activation. The mechanism and functional significance of this recruitment is unclear.

Memory CD8 T cell transcriptional plasticity [PDF]

F1000Prime Reports, 2015
Memory CD8 T cells generated after acute viral infections or live vaccines can persist for extended periods, in some instances for life, and play an important role in protective immunity. This long-lived immunity is achieved in part through cytokine-mediated homeostatic proliferation of memory T cells while maintaining the acquired capacity for rapid ...

Long‐term hippocampal alterations and cognitive impairment in a murine model of surgical sepsis

FEBS Open Bio, EarlyView.
Using a mouse model of surgical sepsis, we tested long‐term memory and analyzed the transcriptome of single cells isolated from the hippocampus. Survivor mice showed worse memory, loss of certain brain cell subpopulations, and abnormal immune cell activity—suggesting that post‐sepsis brain alterations may be linked to cognitive deficits.
