Cytokine signaling pathways are frequent targets of oncogenic mutations in acute myeloid leukemia (AML), promoting proliferation and survival. We have previously shown that the transcription factor PLAGL2 promotes proliferation and cooperates with the leukemia fusion protein Cbfβ-SMMHC in AML development. Here, we show that PLAGL2 upregulates expression of the thrombopoietin receptor Mpl, using two consensus sites in its proximal promoter. We also show that Mpl overexpression efficiently cooperates with Cbfβ-SMMHC in development of leukemia in mice. Finally, we demonstrate that PlagL2-expressing leukemic cells show hyper-activation of Jak2 and downstream STAT5, Akt and Erk1/2 pathways in response to Thpo ligand. These results show that PlagL2 expression activates expression of Mpl in hematopoietic progenitors, and that upregulation of wild-type Mpl provides an oncogenic signal in cooperation with CBFβ-SMMHC in mice.

Single amino acid substitutions in the ATP-binding domain of ACVRL1, a key receptor in the bone morphogenetic protein (BMP) signaling pathway, are frequently classified as variants of uncertain significance (VUS), complicating molecular diagnosis for pulmonary arterial hypertension (PAH) and Hereditary Hemorrhagic Telangiectasia (HHT). Since aberrant ATP binding disrupts downstream SMAD1/5/8 phosphorylation, we employed molecular dynamics ...

Background Cardiac fibrosis represents a significant health burden, with endothelial dysfunction and damaged
perivascular microenvironment increasingly recognized as key contributors to fibrotic remodeling. The urokinase
plasminogen activator receptor (uPAR), a critical component of the urokinase system, plays a pivotal role in vascular
remodeling and fibrosis. While prior evidence indicates that uPAR deficiency leads to microvascular dysfunction and
perivascular fibrosis, ...

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 ...

The transcription factor Fra-2 affects the invasive potential of breast cancer cells by dysregulating adhesion molecules in vitro. Previous results suggested that it upregulates the expression of E- and P-selectin ligands. Such selectin ligands are important members of the leukocyte adhesion cascade, which govern the adhesion and transmigration of cancer cells into the stroma of ...
