Targeted Activation of Ferroptosis in Colorectal Cancer via LGR4 Targeting Overcomes Acquired Drug Resistance

Overcoming Acquired Resistance in Colorectal Cancer by Targeting LGR4 Research Background: Acquired drug resistance is a major obstacle in cancer treatment and a leading cause of cancer-related deaths. However, the mechanisms of resistance are diverse, and how to specifically target resistant cancer cells remains a significant clinical challenge. A...

Unsupervised restoration of a complex learned behavior after large-scale neuronal perturbation

This paper reports on research investigating how zebra finches recover their complex learned behaviors following large-scale neuronal perturbations. The researchers selectively disrupted the activity of the projection neurons in the HVC (hyperpallium ventralis) region critical for song sequence generation in zebra finches using genetic tools, leadi...

Cognitive representations of intracranial self-stimulation of midbrain dopamine neurons depend on stimulation frequency

This paper reports a study on the cognitive representation of intracranial self-stimulation (ICSS) of midbrain dopamine neurons. The authors aimed to answer why rats work to obtain ICSS, i.e., how the pulsatile activation of dopamine neurons is represented in the brain. Research Background: The pulsatile activation of dopamine neurons is typically ...

The subcommissural organ regulates brain development via secreted peptides

The subcommissural organ regulates brain development via secreted peptides

I. Research Background and Purpose The subcommissural organ (SCO) is a glandular structure located at the entrance of the ventricular system, which is present in humans and other vertebrates, but its function has not been fully elucidated. Previous studies have suggested that the SCO may be involved in the regulation of neural development and the m...

Single-cell long-read sequencing-based mapping reveals specialized splicing patterns in developing and adult mouse and human brain

Single-cell sequencing technology reveals unique splicing patterns in developing and adult mouse and human brains In the nervous system, the splicing patterns of messenger RNA (mRNA) play a critical role in establishing cellular identity and regulating cellular functions. However, a comprehensive atlas depicting the mRNA splicing patterns across br...

Cortical gene expression architecture links healthy neurodevelopment to the imaging, transcriptomics and genetics of autism and schizophrenia

Linking Healthy Neurodevelopment with Imaging, Transcriptomic, and Genetic Associations in Autism Spectrum Disorder and Schizophrenia: A Study of Cortical Gene Expression Patterns Background: How does the complex anatomy and functional organization of the human brain develop from the expression of more than 20,000 genes? And how does this process g...

Messenger RNA transport on lysosomal vesicles maintains axonal mitochondrial homeostasis and prevents axonal degeneration

Messenger RNA transport on lysosomal vesicles maintains axonal mitochondrial homeostasis and prevents axonal degeneration

This study utilized induced pluripotent stem cell (iPSC)-derived neurons to investigate the critical role of lysosome-related vesicles in axonal mRNA transport and mitochondrial homeostasis maintenance. By knocking out BORC subunits (borcs5 or borcs7) to block the entry of lysosome-related vesicles into axons, researchers found that this led to a s...

The transcription factor Meis2 promotes the development of projection neurons during mouse embryonic development by binding to and activating projection neuron-specific enhancers with Dlx5

This study investigated the role of the transcription factor Meis2 in regulating the development and differentiation of γ-aminobutyric acid (GABA)ergic neurons during mouse embryonic development. Researchers comprehensively applied techniques such as CRISPR/Cas9 knockdown, single-cell RNA sequencing (scRNA-seq), and lineage tracing, and found that ...

Long-term in vivo three-photon imaging reveals region-specific differences in healthy and regenerative oligodendrogenesis

Long-term in vivo three-photon imaging reveals region-specific differences in healthy and regenerative oligodendrogenesis

This paper reports an original study on the dynamics of oligodendrocytes in the mouse cortex and white matter using three-photon microscopy. Introduction: Oligodendrocytes are the cells that produce myelin in the central nervous system, which is crucial for neural transmission, cognitive function, and injury repair. Previous studies have shown regi...

Revealing Endoplasmic Reticulum Stress-Related CAF Subpopulations Associated with Chordoma Progression

Revealing Endoplasmic Reticulum Stress-Related CAF Subpopulations Associated with Chordoma Progression

Introduction Chordoma is a rare and locally aggressive mesenchymal tumor, believed to originate from the remnant tissues of the primitive notochord. The incidence of chordoma is approximately 0.8 per million, with a predilection for the sacral and skull base regions. Currently, the optimal treatment strategy is maximal safe surgical resection follo...
