Due to the high prevalence of remissions and relapses, novel therapeutic approaches are required to manage OUD. Deep brain stimulation (DBS) is one of the most promising clinical breakthroughs in translational neuroscience. It involves stereotactically implanting electrodes inside the brain and transmitting electrical pulses to targeted areas. To date, the nucleus accumbens has been recognized as the most successful DBS target for treating different types of drug addiction. Nevertheless, further preclinical research is required to determine the optimal brain target and stimulation parameters. On the other hand, the lateral hypothalamic area (LHA) plays a crucial role in many motivated behaviors including food intake and drug-seeking. Additionally, it projects widely throughout the brain to reward-related areas like the ventral tegmental area. Therefore, this chapter reviews studies investigating the potential positive effects of DBS administration in the LHA in animal models of opioid dependence and other pathological conditions. Findings reveal that LHA has the potential to be targeted for DBS application to treat a wide variety of disorders such as opioid dependence, obesity, and sleep disorders without significant adverse events. However, in the context of opioid dependence, more studies are needed, based on more valid animal models of addiction, including self-administration paradigms and varying stimulation patterns, to indicate that LHA is a safe and effective target for DBS in subjects with refractory opioid dependence.","PeriodicalId":51209,"journal":{"name":"Vitamins and Hormones","volume":"127 ","pages":"245-281"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143048706","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

PCa incidences and related deaths in men are a major clinical challenge that needs immediate attention to prevent, manage, or treat the disease to improve overall health in patients. Activation of androgen receptor (AR) signaling and subsequent transactivation of downstream genes play a predominant role in PCa development, progression, and metastasis. Over the last few decades, the role of epigenetics has been much appreciated in the pathogenesis of PCa. There is widespread involvement of several epigenetic changes (such as DNA modifications by methylation, histone modifications by acetylation, chromatin remodellers, and non-coding RNAs, etc.) in the regulation of PCa initiation, progression, as well as the emergence of androgen-insensitive castration-resistant PCa (CRPC) phenotype, which has improved our understanding of disease etiology. Moreover, targeting selective epigenetic marks has raised immense opportunities to target PCa, owing to the possibilities of reversal of epigenetic changes involved in the disease progression. Several epigenetic inhibitors (e.g., DNMT inhibitors, HDAC inhibitors) have been investigated in preclinical studies as well as in clinical trials to establish effective epigenetic-based therapies against PCa, and indeed, few of them have already made their way to the clinic. Epigenetics also plays a role in the reactivation of AR signaling in CRPC; though hormonal therapies are ineffective in these tumors, epigenetic inhibitors combined with other therapies are considered important in targeting CRPC. Here, we have summarized epigenetics in the regulation of AR signaling, progress in understanding epigenetics' role in etiology, and the importance of designing effective therapies for PCa, including CRPC. We have also discussed the limitations and challenges in epigenetics therapies and strategies to overcome obstacles in improving existing therapies to better manage PCa disease in clinics.","PeriodicalId":51209,"journal":{"name":"Vitamins and Hormones","volume":"129 ","pages":"143-183"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144857006","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Altered energy metabolism, such as increased glycolysis, is a critical hallmark of most human cancers. Therefore, small-molecule GLUT inhibitors are promising bioprobes for understanding complex tumor metabolism and may serve as new candidate drugs for cancer therapy. Certain naturally occurring flavonoids have been shown to inhibit glucose uptake by GLUTs. Recently, a variety of potent and selective GLUT inhibitors of different chemotypes have been developed to target glycolysis-addicted tumors.

Most men with prolactinomas present with large and invasive tumors. Despite effective medical therapy with dopamine agonists and prolactin normalization, over 20 % of men with prolactinomas will remain with hypogonadism. There are two suggested mechanisms for hypogonadism: central suppression of the hypothalamic-pituitary-gonadal axis caused by elevated prolactin levels leading to inhibition of the kisspeptin neurons in the hypothalamus and loss of pulsatile luteinizing hormone secretion, and tumor mass effect with compression of the normal pituitary tissue and destruction of gonadotroph cells. Hypogonadism in men results in sexual dysfunction, low libido, anemia, fatigue, and infertility. Identification of patients who are likely to recover the damaged gonadal axis upon prolactin suppression is important. These are men that harbor smaller tumors, with higher testosterone levels at diagnosis, no visual field defects, and without impairment in the secretion of other pituitary hormones. Testosterone replacement should be offered to patients with lower chance of restoring normal function of the gonadal axis. However, most men will achieve spontaneous recovery of the hypothalamic-pituitary-gonadal axis within 12 months after prolactin normalization. For men with prolactinoma and hypogonadism persistence who wish to restore fertility, treatment with gonadotropins or with clomiphene citrate has been found to be safe and effective. In the present review, we propose an algorithm for the management of hypogonadism persistence in men with macroprolactinomas.","PeriodicalId":51209,"journal":{"name":"Vitamins and Hormones","volume":"129 ","pages":"185-202"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144857004","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conventional treatment options for breast cancer include surgery, chemotherapy, and radiotherapy. However, these therapies can frequently have adverse side effects and may not be effective for all patients. In recent years, there has been an increasing interest in the development of targeted therapies for breast cancer. Glut-1, a key glucose transporter that is often overexpressed in breast cancer cells, is a potential candidate for targeted therapies. Glut-1 is crucial for basal glucose transport into cancer cells and is necessary for their rapid growth and survival. Several Glut-1 inhibitors - both natural and synthetic small molecules - have been identified and used as anticancer agents. In this chapter, we summarize the different approaches of Glut-1 inhibition in breast cancer and the mode of inhibition used by various Glut-1 inhibitors. Further understanding of the mechanisms underlying the efficacy of Glut-1 inhibitors in breast cancer treatment may provide crucial insights that can lead to the advancement of current treatment strategies. The functional inhibition of Glut-1 by specific Glut-1 inhibitors is being explored as a potential treatment modality for breast cancer. This approach holds great promise for improving the therapeutic efficacy of breast cancer treatment and minimizing the side effects associated with conventional therapies.","PeriodicalId":51209,"journal":{"name":"Vitamins and Hormones","volume":"128 ","pages":"181-211"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143651847","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hypothalamic neuropeptides have been involved in a large plethora of mechanisms related with obesity, anxiety, feeding, energy metabolism, defensive behavior, mood, and reproduction. The therapeutic potential of these findings is enormous but the physiological complexity occurring in the hypothalamus is huge due in part to the interactions between numerous neuropeptides as well as between neuropeptides and other neuroactive substances. Here, we review the development and neuroanatomy of the hypothalamus as well as the involvement of 31 neuropeptides in hypothalamic functions and pathologies. Alterations in the secretion, release, and/or concentrations of neuropeptides and/or their hypothalamic receptors can trigger different pathologies. Several therapeutic strategies that could be carried out by adjusting neuropeptide levels in the hypothalamus are suggested. The combination of imaging techniques with a detailed neurochemical knowledge of the hypothalamus would be an excellent diagnostic tool, allowing personalized treatment. Several approaches for future research that may contribute to improve or resolve these pathologies are also mentioned.","PeriodicalId":51209,"journal":{"name":"Vitamins and Hormones","volume":"127 ","pages":"1-50"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143048702","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Further investigation into the molecular underpinnings of this process revealed interconnected signaling between the CDK4/6 and estrogen receptor (ER) signaling axes, providing evidence that CDK4/6i would be particularly relevant in estrogen-driven cancers. Three FDA-approved CDK4/6 inhibitors, palbociclib, ribociclib, and abemaciclib, were independently developed and all exhibited efficacy against in vivo models of ER+ breast cancer. Clinical trials then confirmed the safety and efficacy of these drugs in patients. Ongoing clinical trials are now testing CDK4/6i in several other cancer models, including other hormone-driven cancers.

The hypothalamus is the higher center of the autonomic nervous system and is involved in the regulation of various homeostatic mechanisms. It also modulates respiration by facilitating the respiratory network. Among subregions of the hypothalamus, the paraventricular nucleus, lateral hypothalamic area, perifornical area, dorsomedial and posterior hypothalamus play particularly important roles in respiratory control. Neurons in these regions have extensive and complex interconnectivity with the cerebral cortex, pons, medulla, spinal cord, and other brain areas. These hypothalamic regions are involved in the maintenance of basal ventilation, respiratory responses to hypoxic and hypercapnic conditions, respiratory augmentation during dynamic exercise, and respiratory modulation in awake and sleep states. Disorders affecting the hypothalamus such as narcolepsy, ROHHAD syndrome, and Prader-Willi syndrome could lead to respiratory abnormalities. However, the role of the hypothalamus in respiratory control, especially its interplay with other local respiratory networks has not yet been fully elucidated. Further clarification of these issues would contribute to a better understanding of the hypothalamus-mediated respiratory control and the pathophysiology of respiratory disorders underlain by hypothalamic dysfunction, as well as to the development of new targeted therapies.","PeriodicalId":51209,"journal":{"name":"Vitamins and Hormones","volume":"127 ","pages":"125-152"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143048687","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
