Tumor hypoxia is one of the main reasons of progression and metastasis of colorectal cancer. The important molecular mechanism of cell response to hypoxia consists in up- or down-regulation of microRNA expression. In this work we performed microRNA and mRNA sequencing of human colorectal adenocarcinoma HT-29 cell lines treated with two chemical agents mimicking hypoxia: cobalt (II) chloride and oxyquinoline. Bioinformatics analysis of the obtained data revealed differentially expressed isomiRs (hsa-miR-210-3p|0, hsa-miR-22-3p|0, hsa-let-7a-3p|0, hsa-miR-615-3p|0, hsa-miR-4521|0) and their targets, which changed their expression upon hypoxia induction by both treatments. Thus, we identified new regulatory mechanisms of cellular response to hypoxia.

Emotion regulation (ER) involves processes by which individuals modulate the intensity, duration, and expression of emotional responses, and its dysregulation is associated with a broad spectrum of psychological disorders. While traditionally conceptualized within psychological frameworks, ER is increasingly recognized as biologically grounded, involving intricate interactions between neurochemical, hormonal, and metabolic systems. This narrative review aims ...

Motor imagery (MI) allows individuals to mentally simulate movements without execution, engaging neural pathways that overlap with those used during real actions. However, how imagery perspective influences corticospinal excitability across different effectors remains unclear. Using neuronavigated transcranial magnetic stimulation (TMS), we compared kinesthetic (KMI), first-person visual (VMI-1PP), and third-person visual (VMI-3PP) imagery of elbow flexion-extension ...

We present a multimodal dataset containing electroencephalography (EEG), electrocardiography (ECG), and video recordings from 49 participants. Each participant completed a single session lasting approximately 45 minutes. During each session they performed five tasks: resting state, inward concentration (focusing on the center of the forehead), outward concentration (visual search), and mind-wandering. EEG data were recorded from ...

Multidrug resistance (MDR) remains one of the principal challenges in cancer chemotherapy, necessitating new strategies to restore drug efficacy. In this study we developed and characterize a redox-responsive nanoplatform based on trithiocyanuric acid and polyethylene glycol (TTCA-PEG NPs) as a potential tool to overcome MDR and provide a biocompatible delivery system for conventional antitumor drugs. ...

Introduction:
While self-referential attention is thought to enhance interoceptive sensitivity, its effect on cardiac modulation of corticospinal excitability remains unexplored. This pilot study investigated how viewing one’s own face (self-face processing) modulates the cardiac-phase coupling of motor output and whether this heart-brain coupling depends on interoceptive accuracy (heartbeat perception).
Methods:
In 15 healthy adults, motor-evoked potentials (MEPs) were ...

Background: Neuroblastoma (NB), a transcriptionally driven pediatric malignancy, exhibits a remarkable clinical and biological heterogeneity. Two major subtypes, adrenergic and mesenchymal, are differentially governed by distinct subsets of transcription factors that constitute the core regulatory circuitry (CRC). The adrenergic subtype is often associated with MYCN amplification and is particularly aggressive and therapy-resistant, underscoring the need ...

Pediatric tumors such as neuroblastoma are characterized by a genome-wide ‘transcriptional burden’, surmising the involvement of multiple alterations of gene expression. Search for master regulators of transcription whose inactivation is lethal for tumor cells identified the non-POU domain-containing octamer-binding protein (NONO), a member of the Drosophila Behavior/Human Splicing family known for the ability to form ...

Copper–organic compounds are being investigated as antitumor candidates. Besides their efficacy as cytotoxic agents alone, the oxidative potential of electrochemical Cu2+-to-Cu1+ transition emerges as an attractive approach for elimination of tumor cells otherwise resistant to chemotherapy. To minimize side effects of the potent oxidative burst upon Cu(II) reduction, the metal cations should be delivered to the ...

Background. Individual activation maps based on brain functional magnetic resonance imaging (fMRI) data cannot yet be applied to refine a patient's diagnosis and prognosis. However, tracking activation dynamics in the same patient during the course of treatment or rehabilitation can be useful for assessing their efficacy. Population-based studies often fail to identify clinically significant activation parameters ...

Emotion regulation is aimed to control emotional states through various strategies, among which reappraisal and suppression have been extensively studied up to date. Nevertheless, physiological correlates of this process are still debatable, since findings on both brain and peripheral activity are contradictory. In the present work, we were first to investigate neural sources and inter-subject ...
