Although initially discovered and extensively studied for its role in inflammation, Annexin A1 (ANXA1) has been reported to be closely related to cancer in recent years, and its role in cancer is specific to tumor types and tissues. In the present study, we identified ANXA1 as an interaction partner of glycogen synthase kinase 3 beta (GSK3β), a multi-functional serine/threonine kinase tightly associated with cell fate determination and cancer, and assessed the functional significance of GSK3β-ANXA1 interaction in the metastasis of non-small cell lung cancer (NSCLC). We confirmed the interaction between GSK3β and ANXA1 in vitro and in H1299 and A549 cells by Glutathione-S-transferase (GST) pull-down assay and co-immunoprecipitation. We found that ANXA1 negatively regulated the phosphorylation of GSK3β and inhibited the epithelial-mesenchymal transformation (EMT) process and migration and invasion of NSCLC cells. By functional rescue assay, we confirmed that ANXA1 inhibited EMT through the regulation of GSK3β activity and thereby inhibited the migration and invasion of NSCLC cells. Our study sheds light on the function of ANXA1 and GSK3β and provides new elements for the understanding of NSCLC pathogenesis.Insulin and insulin-like growth factor stimulate protein synthesis and cardioprotection in the heart, acting through their receptors (INSRs, IGF1Rs) and signalling via protein kinase B (PKB, also known as Akt). Protein synthesis is increased in hearts perfused at alkaline pHo to the same extent as with insulin. Moreover, α1-adrenergic receptor (α1-AR) agonists (e.g. phenylephrine) increase protein synthesis in cardiomyocytes, activating PKB/Akt. In both cases, the mechanisms are not understood. Our aim was to determine if insulin receptor-related receptors (INSRRs, activated in kidney by alkaline pH) may account for the effects of alkaline pHo on cardiac protein synthesis, and establish if α1-ARs signal through the insulin receptor family. Alkaline pHo activated PKB/Akt signalling to the same degree as insulin in perfused adult male rat hearts. INSRRs were expressed in rat hearts and, by immunoblotting for phosphorylation (activation) of INSRRs/INSRs/IGF1Rs, we established that INSRRs, together with INSRs/IGF1Rs, are activated by alkaline pHo. The INSRR/INSR/IGF1R kinase inhibitor, linsitinib, prevented PKB/Akt activation by alkaline pHo, indicating that INSRRs/INSRs/IGF1Rs are required. #link# Activation of PKB/Akt in cardiomyocytes by α1-AR agonists was also inhibited by linsitinib. Furthermore, Withaferin A solubility dmso induced by α1-ARs in cultured cells, reduced the initial cardiac adaptation (24 h) to phenylephrine in vivo (assessed by echocardiography) and increased cardiac fibrosis over 4 days. We conclude that INSRRs are expressed in the heart and, together with INSRs/IGF1Rs, the insulin receptor family provide a potent system for promoting protein synthesis and cardioprotection. Moreover, this system is required for adaptive hypertrophy induced by α1-ARs.
Alcohol consumption influences the water balance in the brain. While the impact of chronic alcohol misuse on cerebral water content has been the subject of several studies, less is known about the effects of acute alcohol misuse, with contradictory results in the literature. Therefore, we investigated the effects of acute alcohol intoxication on cerebral water content using a precise quantitative magnetic resonance imaging (MRI) sequence.

In a prospective study, we measured cerebral water content in 20 healthy volunteers before alcohol consumption and after reaching a breath alcohol concentration of 1 ‰. A quantitative MRI water mapping sequence was conducted on a clinical 3 T system. Non-alcoholic fluid input and output were documented and accounted for. Water content was assessed for whole brain, grey and white matter and more specifically for regions known to be affected by acute or chronic alcohol misuse (occipital and frontal lobes, thalamus and pons). Changes in the volume of grey and white matter as well as the whole brain were examined.

Quantitative cerebral water content before and after acute alcohol consumption did not differ significantly (P≥0.07), with changes often being within the range of measurement accuracy. Whole brain, white and grey matter volume did not change significantly (P≥0.12).

The results of our study show no significant water content or volume change in the brain after recent alcohol intake in healthy volunteers. This accounts for the whole brain, grey and white matter, occipital and frontal lobes, thalamus and pons.

Enhanced external counterpulsation (EECP) is a non-invasive treatment (35 one-hour sessions) for patients with refractory angina pectoris (RAP). To avoid interruption of treatment, more knowledge is needed about potential adverse events (AE) of EECP and their appropriate management. To describe occurrence of AE and clinical actions related to EECP treatment in patients with RAP and compare the distribution of AE between responders and non-responders to treatment.

A retrospective study was conducted by reviewing medical records of 119 patients with RAP who had undergone one EECP treatment and a 6-min-walk test pre- and post-treatment. Sociodemographic, medical, and clinical data related to EECP were collected from patients' medical records. An increased walking distance by 10% post-treatment, measured by 6-min-walk test, was considered a responder. The treatment completion rate was high, and the occurrence of AE was low. Adverse events occurred more often in the beginning and gradually decreased towards the end of EECP treatment. The AE were either device related (e.g. muscle pain/soreness) or non-device related (e.g. bradycardia). Medical (e.g. medication adjustments) and/or nursing (e.g. extra padding around the calves, wound dressing) actions were used. The AE distribution did not differ between responders (n = 49, 41.2%) and non-responders. Skin lesion/blister occurred mostly in responders and paraesthesia occurred mostly in non-responders.

Enhanced external counterpulsation appears to be a safe and well-tolerated treatment option in patients with RAP. However, nurses should be attentive and flexible to meet their patients' needs to prevent AE and early termination of treatment.
