This article reviews the various aspects of the multifaceted biology of PCSK7 and what makes it an exciting new target for metabolic dysfunction-associated steatotic liver disease (MASLD) affecting ∼30% of the population globally, dyslipidemia, cardiovascular disease (CVD), and likely cancer/metastasis. We will systematically review and discuss all the available epidemiological data, structural, cell biology, and in vivo evidence that eventually led to the discovery of PCSK7 as a novel post-translational regulator of apolipoprotein B. Interestingly, PCSK7 is the only convertase, other than PCSK9, that exhibits non-canonical/non-enzymatic functions, which will be amply described in this review. The data so far suggested that PCSK7 is a potential safe target in MASLD treatment. This was based on human epidemiological data, as well as mouse Pcsk7 knockout and mRNA translation inhibition using hepatocyte-targeted antisense oligonucleotides following a diet-induced MASLD. Additionally, of all the 9 convertases only the gene deletion of Pcsk7 and/or Pcsk9 in mice leads to healthy and fertile animals with no apparent deleterious consequences, suggesting that their pharmacological targeting is likely safe. Accordingly, the synergistic effects of inhibiting both PCSK7 and PCSK9 in a clinical setting may represent a novel therapy for various diseases. We believe that the current surge in oligonucleotide therapy, with many FDA-approved oligonucleotide-based drugs now available in the clinics, and the urgent need for novel MASLD therapeutics present an opportune moment for this timely review article.</p>","PeriodicalId":11544,"journal":{"name":"Endocrine reviews","volume":" ","pages":""},"PeriodicalIF":22.0,"publicationDate":"2024-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142812348","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An increasingly persuasive and large body of evidence over the last 70 years concur that GH action is implicit in escalating several cancer-associated events, locally and systemically. This pleiotropy of GH's effects is puzzling, but the association with cancer-risk automatically raises a concern for patients with acromegaly and for individuals treated with GH. By careful assessment of the available knowledge on the fundamental concepts of cancer, suggestions from epidemiological and clinical studies, and the evidence from specific reports, in this review we aimed to help clarify the distinction of endocrine vs. autocrine/paracrine GH in promoting cancer and reconcile the discrepancies between experimental and clinical data. Along this discourse, we critically weigh the targetability of GH action in cancer - firstly by detailing the molecular mechanisms which posit GH as a critical node in tumor circuitry, and secondly, by enumerating the currently available therapeutic options targeting GH action.

In addition, a number of systemic and inflammatory disorders can also affect the parasellar region, most commonly involving the pituitary. These lesions have different pathologic characteristics and malignant potential according to the new World Health Organization CNS5 2021 classification. Signs and symptoms may be nonspecific and are mostly related to a mass effect on the surrounding anatomical structures and/or impairment of endocrine function, whereas the vast majority lack a secretory component.

These developments may serve as a powerful means to delineate the pathophysiology of these lesions and serve as a diagnostic, prognostic, and therapeutic tool, particularly for high-risk populations.

Current assessment of GC status is primarily clinical, often in conjunction with serum cortisol values, which may be stimulated or suppressed depending on the GC disturbance being assessed. In the setting of extreme perturbations in cortisol levels ie, markedly low or high levels, symptoms and signs of GC dysfunction may be overt. However, when disturbances in cortisol GC status values are less extreme, such as when assessing optimization of a GC replacement regimen, signs and symptoms can be more subtle or nonspecific. Current tools for assessing GC status are best suited to identifying profound disturbances but may lack sensitivity for confirming optimal GC status. Moreover, single cortisol values do not necessarily reflect an individual's GC status, as they are subject to inter- and intraindividual variation and do not take into account the pulsatile nature of cortisol secretion, variation in binding proteins, or local tissue concentrations as dictated by 11beta-hydroxysteroid dehydrogenase activity, as well as GC receptor sensitivity. In the present review, we evaluate possible alternative methods for the assessment of GC status that do not solely rely on the measurement of circulating cortisol levels.

It may also present in those who are hypothyroid or euthyroid. The characteristic clinical manifestations of TED, chemosis, lid swelling, proptosis, and diplopia, are driven by a combination of inflammation and extracellular matrix modification. It has recently emerged that 1 of the major drivers of this molecular signature is the overexpression of the IGF-1 receptor [IGF-1R]) on key effector cells in TED pathogenesis. The overexpression of the IGF-1R is coupled with a dysregulation of the IGF-1R axis, which links other pathways that modulate inflammation, such as fibrosis and extracellular matrix organization, in patients with TED. This overexpression is also found to persist from the acute stage into the chronic phase. Teprotumumab, a fully human IgG1 monoclonal antibody that inhibits the IGF-1R, recently gained approval in the United States for the treatment of TED. In phase 2 and phase 3 clinical studies, teprotumumab showed efficacy in reducing inflammation, proptosis, diplopia, and burden on quality of life in patients who were treated. Postintroduction studies have confirmed the results of the phase 2 and phase 3 studies. Since 2020, more than 5800 patients have been treated with teprotumumab, and it appears to be well tolerated.
