CREB coactivator CRTC1 in melanocortin-4 receptor-expressing cells regulate dietary fat intake.

Cyclic adenosine monophosphate-response element-binding protein-1-regulated transcription coactivator-1 (CRTC1), a cytoplasmic coactivator that translocates to the nucleus in response to cAMP, is associated with obesity. We previously reported that deficiency in melanocortin-4 receptor (MC4R)-expressing neurons, which regulate appetite and energy metabolism in the brain, causes hyperphagia and obesity under a high-fat diet (HFD). HFD is preferred for mice, and the dietary fat in HFD is the main factor contributing to its palatability.

[Regulation of the Tumor Microenvironment through HER2 Signaling-Insights from Gastric Cancer Cases with Heterogeneous HER2 Overexpression].

HER2, a member of the human epidermal growth factor receptor(HER)family, exhibits gene amplification, protein overexpression, or both in 13-27% of gastric cancer(GC)cases. Through the activation of downstream Akt and ERK pathways, HER2 promotes the survival and proliferation of gastric cancer cells. The impact of HER2 signaling on the tumor microenvironment(TME)in GC remains unclear, and the heterogeneity of HER2 overexpression in GC tissues is considered a contributing factor.

The effects of online facial muscle training with resonance vocalization on mental health in postpartum women: A single-arm pilot study.

Background: Mental health problems among expectant and nursing mothers also affect their infants, partners, and families. While physical activity is a potential method for preventing postpartum depression (PPD), it is difficult for postpartum women to find the time for physical exercise. A recent study reported that improving communication between expectant couples can be used as a preventive intervention for PPD, and a systematic review and meta-analysis recently reported decreased facial emotional expressivity in individuals with different non-psychotic disorders.

CVIT expert consensus document on primary percutaneous coronary intervention (PCI) for acute coronary syndromes (ACS) in 2024.

Primary Percutaneous Coronary Intervention (PCI) has significantly contributed to reducing the mortality of patients with ST-segment elevation myocardial infarction (STEMI) even in cardiogenic shock and is now the standard of care in most of Japanese institutions. The Task Force on Primary PCI of the Japanese Association of Cardiovascular Intervention and Therapeutics (CVIT) proposed an expert consensus document for the management of acute myocardial infarction (AMI) focusing on procedural aspects of primary PCI in 2018 and updated in 2022. Recently, the European Society of Cardiology (ESC) published the guidelines for the management of acute coronary syndrome in 2023.

High levels of tumor cell-intrinsic STING signaling are associated with increased infiltration of CD8 T cells in dMMR/MSI-H gastric cancer.

Mismatch repair deficient (dMMR)/microsatellite instability-high (MSI-H) gastric cancer (GC) exhibits an immune-active tumor microenvironment (TME) compared to MMR proficient (pMMR)/microsatellite stable/Epstein-Barr virus-negative [EBV (-)] GC. The tumor cell-intrinsic cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) pathway has been considered a key regulator of immune cell activation in the TME. However, its significance in regulating the immune-active TME in dMMR/MSI-H GC remains unclear.
