Biomedicines 2023; 11:2217. [PMID: 37626714 PMCID: PMC10452353 DOI: 10.3390/biomedicines11082217] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2023] [Revised: 08/02/2023] [Accepted: 08/05/2023] [Indexed: 08/27/2023] Open
Abstract
Since the corticotropin-releasing factor (CRF) was isolated from an ovine brain, a growing family of CRF-related peptides has been discovered. Today, the mammalian CRF system consists of four ligands (CRF, urocortin 1 (Ucn1), urocortin 2 (Ucn2), and urocortin 3 (Ucn3)); two receptors (CRF receptor type 1 (CRF1) and CRF receptor type 2 (CRF2)); and a CRF-binding protein (CRF-BP). Besides the regulation of the neuroendocrine, autonomic, and behavioral responses to stress, CRF and CRF-related peptides are also involved in different aspects of social behavior. In the present study, we review the experiments that investigated the role of CRF and the urocortins involved in the social behavior of rats, mice, and voles, with a special focus on sociability and preference for social novelty, as well as the ability for social recognition, discrimination, and memory. In general, these experiments demonstrate that CRF, Ucn1, Ucn2, and Ucn3 play important, but distinct roles in the social behavior of rodents, and that they are mediated by CRF1 and/or CRF2. In addition, we suggest the possible brain regions and pathways that express CRF and CRF-related peptides and that might be involved in social interactions. Furthermore, we also emphasize the differences between the species, strains, and sexes that make translation of these roles from rodents to humans difficult.

Abstract
OBJECTIVE To summarize current concepts on neuroendocrine and genetic principles underlying stress-related depression and to discuss the challenges of personalized treatment in depression. METHODS Review of the literature pertaining to genetic and neuroendocrine basis of stress-related depression including aspects of treatment response with a focus on the hypothalamus-pituitary-adrenal (HPA) axis. RESULTS There is increasing evidence that genetic polymorphisms and dysregulation of the HPA axis are associated with the pathophysiology of stress-related depression. Individual stress hormone reactivity seems to be determined by a combination of genetic and environmental factors, contributing to both, resilience or vulnerability. CONCLUSIONS Although substantial progress has been made, current knowledge is still limited. Further basic and clinical research is needed to identify specific subgroups and to minimize heterogeneity of the depression phenotype. A better characterization is essential to detect genetic and functional predictors of antidepressant treatment response to follow the vision of personalized therapy in psychiatry.

Abstract
OBJECTIVES To determine the prevalence of major depressive disorder (MDD) and other selected axis-I disorders among women with newly diagnosed, untreated endocrine disorders. METHODS Two hundred and eighteen consecutive women, aged 18-65, with newly diagnosed, untreated endocrine disorders were referred for potential diagnosis of co-morbid axis-I disorders with the use of the Structured Clinical Interview for Axis I-Patient Edition (SCID-P). The SCID-P was re-administered after 12 weeks. RESULTS At baseline, 64 (29.3%) women met criteria for at least one axis-I disorder. Women who were diagnosed with hyperthyroidism were more likely to meet criteria for generalized anxiety disorder and panic disorder than women without hyperthyroidism. Nine of 154 (5.8 %) women who did not meet criteria for an axis-I disorder at baseline met criteria for at least one axis-I disorder during follow-up. Among them, the presence of diabetes mellitus was statistically correlated with a higher probability of developing major depressive disorder at follow-up. CONCLUSIONS Although preliminary, our findings are consistent with previous studies and suggest an increased prevalence of MDD and other axis-I disorders among women with newly diagnosed endocrine disorders, providing further evidence suggesting that women with endocrine abnormalities may be at increased risk of depression and/or anxiety disorders.

Abstract
There is growing evidence that aberrant transcriptional regulation is one of the key components of the pathophysiology of mood disorders. The repressor element-1 silencing transcription factor (REST) is a negative regulator of genes that contain the repressor element-1 (RE-1) binding site. REST has many target genes, including corticotropin releasing hormone (CRH), brain-derived neurotrophic factor, serotonin 1A receptor, which are suggested to be involved in the pathophysiology of depression and the action of antidepressants. However, a potential role for REST-mediated transcriptional regulation in mood disorders remains unclear. In this study, we examined the mRNA levels of REST and its known and putative target genes, using quantitative real-time PCR in peripheral blood cells of patients with major depressive and bipolar disorders in both a current depressive and a remissive state. We found reduced mRNA expression of REST and increased mRNA expression of CRH, adenylate cyclase 5, and the tumor necrosis factor superfamily, member 12-13 in patients with major depressive disorder in a current depressive state, but not in a remissive state. Altered expression of these mRNAs was not found in patients with bipolar disorder. Our results suggest that the aberrant REST-mediated transcriptional regulation of, at least, CRH, adenylate cyclase 5, and tumor necrosis factor superfamily, member 12-13, might be state-dependent and associated with the pathophysiology of major depression.

Abstract
The neuropeptide oxytocin (OT) modulates social behaviours and is an important anxiolytic substance of the brain. However, sites of action and the intracellular signalling pathways downstream of OT receptors (OTR) within the brain remain largely unknown. In the present studies, we localized the anxiolytic effect of OT by bilateral microinfusion of OT (0.01 nmol/0.5 microL) into the hypothalamic paraventricular nucleus (PVN) in male rats using both the elevated plus-maze and the light-dark box. Moreover, intracerebroventricular administration of OT, but not of the related neuropeptide vasopressin (VP), dose-dependently activated the extracellular signal-regulated kinase 1/2 (ERK1/2) cascade. Specifically, OT induced the phosphorylation of Raf-1, MEK1/2 and ERK1/2 in the hypothalamus in vivo and in hypothalamic H32 neurons via EGF receptors. OT-induced ERK1/2 phosphorylation was immunohistochemically localized within VP neurons of the PVN and the supraoptic nucleus. Importantly, the anxiolytic effect of OT within the PVN was prevented by local inhibition of the MAP kinase cascade with a MEK1/2 inhibitor (U0126, 0.5 nmol/0.5 microL) locally infused prior to OT, indicating the causal involvement of this intracellular signalling cascade in the behavioural effect of OT. OT effects within the hypothalamus may have far-reaching implications for the regulation of emotionality and social behaviours and, consequently, for the development of possible therapeutic strategies to treat affective disorders. Thus, OTR agonism or activation of the ERK1/2 cascade, specifically within the hypothalamus, may provide therapeutically relevant mechanisms.

Abstract
The identification, referral and specific treatment of midlife patients in primary care who are distressed by mood, anxiety, sleep and stress-related symptoms, with or without clinically confirmed menopausal symptoms, are confounded by many structural issues in the delivery of women's healthcare. Diagnosis, care delivery, affordability of treatment, time commitment for treatment, treatment specificity for a particular patient's symptoms and patient receptiveness to diagnosis and treatment all play roles in the successful amelioration of symptoms in this patient population. The value of screening for depression in primary care, the limitations of commonly used screening instruments relative to culture and ethnicity, and which clinical care systems make best use of diagnostic screening programs will be discussed in the context of the midlife woman. The Sequenced Treatment Alternatives to Relieve Depression (STAR*D) program illustrates the relatively high rate of unremitted patients, regardless of clinical setting, who are receiving antidepressants. Nonmedication treatment approaches, referred to in the literature as 'nonsomatic treatments', for depression, anxiety and stress, include different forms of cognitive-behavioral therapy, interpersonal therapy, structured daily activities, mindfulness therapies, relaxation treatment protocols and exercise. The specificity of these treatments, their mechanisms of action, the motivation and time commitment required of patients, and the availability of trained practitioners to deliver them are reviewed. Midlife women with menopausal symptoms and depression/anxiety comorbidity represent a challenging patient population for whom an individualized treatment plan is often necessary. Treatment for depression comorbid with distressing menopausal symptoms would be facilitated by the implementation of a collaborative care program for depression in the primary care setting.
