Muscle Damage in Systemic Sclerosis and CXCL10: The Potential Therapeutic Role of PDE5 Inhibition. Int J Mol Sci 2021; 22:2894. [PMID: 33809279 PMCID: PMC8001273 DOI: 10.3390/ijms22062894] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2021] [Revised: 03/09/2021] [Accepted: 03/10/2021] [Indexed: 02/07/2023] Open
Abstract
Skeletal muscle damage is a common clinical manifestation of systemic sclerosis (SSc). C-X-C chemokine ligand 10 (CXCL10) is involved in myopathy and cardiomyopathy development and is associated with a more severe SSc prognosis. Interestingly, the phosphodiesterase type 5 inhibitor (PDE5i) sildenafil reduces CXCL10 sera levels of patients with diabetic cardiomyopathy and in cardiomyocytes. Here, we analyzed the levels of CXCL10 in the sera of 116 SSc vs. 35 healthy subjects and explored differences in 17 SSc patients on stable treatment with sildenafil. CXCL10 sera levels were three-fold higher in SSc vs. healthy controls, independent of subset and antibody positivity. Sildenafil treatment was associated with lower CXCL10 sera levels. Serum CXCL10 strongly correlated with the clinical severity of muscle involvement and with creatine kinase (CK) serum concentration, suggesting a potential involvement in muscle damage in SSc. In vitro, sildenafil dose-dependently reduced CXCL10 release by activated myocytes and impaired cytokine-induced Signal transducer and activator of transcription 1 (STAT1), Nuclear factor-κB (NFκB) and c-Jun N-terminal kinase (JNK) phosphorylation. This was also seen in cardiomyocytes. Sildenafil-induced CXCL10 inhibition at the systemic and human muscle cell level supports the hypothesis that PDE5i could be a potential therapeutic therapy to prevent and treat muscle damage in SSc.

Abstract
The adult adrenal cortex is organized into concentric zones, each specialized to produce distinct steroid hormones. Cellular composition of the cortex is highly dynamic and subject to diverse signaling controls. Cortical homeostasis and regeneration rely on centripetal migration of steroidogenic cells from the outer to the inner cortex, which is accompanied by direct conversion of zona glomerulosa (zG) into zona fasciculata (zF) cells. Given the important impact of tissue structure and growth on steroidogenic function, it is essential to understand the mechanisms governing adrenal zonation and homeostasis. Towards this end, we review the distinctions between each zone by highlighting their morphological and ultra-structural features, discuss key signaling pathways influencing zonal identity, and evaluate current evidence for long-term self-renewing stem cells in the adult cortex. Finally, we review data supporting zG-to-zF transdifferentiation/direct conversion as a major mechanism of adult cortical renewal.

Abstract
CONTEXT Recent studies have identified that the somatic PRKACA L206R mutation can cause cortisol-producing adenomas (CPAs). This study investigated the prevalence and characteristics of PRKACA, GNAS and CTNNB1 mutations in adrenal lesions in patients from a single centre in China. DESIGN, PATIENTS AND MEASUREMENTS We sequenced PRKACA, GNAS and CTNNB1 genes in 108 patients, including 60 patients with CPAs (57 with unilateral and three with bilateral adenomas), 13 with nonfunctional adenomas, 12 with adrenocortical carcinomas (ACCs), 15 with primary bilateral macronodular hyperplasia (PBMAH) and eight with aldosterone and cortisol cosecreting adenomas. Mutations in PRKACA, GNAS and CTNNB1 were examined, and clinical characteristics were compared. RESULTS Among the unilateral CPAs, we identified somatic mutations in PRKACA (L206R) in 23 cases (40·4%), GNAS (R201C and R201H) in six cases (10·5%), CTNNB1 (S45C, L46P and S45P) in six cases (10·5%) and CTNNB1 plus GNAS in two cases (3·5%). PRKACA and GNAS mutations were mutually exclusive. Among the patients with nonfunctional adenoma, two carried CTNNB1 mutations. Among the patients with ACC, two carried GNAS and CTNNB1 mutations but none carried PRKACA mutations. One patient showed bilateral CPA, and one PBMAH patient carried PRKACA mutations. No mutations in PRKACA, GNAS or CTNNB1 were identified in the eight patients with aldosterone and cortisol cosecreting adenomas. PRKACA-mutant adenomas were associated with young age, overt Cushing's syndrome and high cortisol levels compared with non-PRKACA-mutant or CTNNB1-mutant lesions. CONCLUSIONS PRKACA mutations are present in CPAs and bilateral adrenal macronodular hyperplasia. PRKACA mutation is associated with more severe autonomous cortisol secretion.

Abstract
The adrenocortical tumorigenesis is a complex process, which involves multiple genetic changes. A better knowledge on the mechanisms involved in tumor development would enable an early identification of malignant disease and also lead to the development of new treatment strategies. Although in the recent years a large amount of data was produced, the exact mechanisms that lead to adrenocortical tumor development remains poorly understood. Most of the studies produced were based on the candidate-gene strategy, which has its own limitations. A genome-wide approach, such as microarrays, will surely shed some light into the mechanisms responsible for adrenocortical tumorigenesis. In this review, we summarize the most recent data available on this complex process.

Abstract
BACKGROUND: Malignant neoplasia of the adrenal cortex is usually associated with very poor prognosis. When adrenocortical neoplasms are diagnosed in the early stages, distinction between carcinoma and adenoma can be very difficult to accomplish, since there is yet no reliable marker to predict tumor recurrence or dissemination. GATA transcription factors play an essential role in the developmental control of cell fate, cell proliferation and differentiation, organ morphogenesis, and tissue-specific gene expression. Normal mouse adrenal cortex expresses GATA-6 while its malignant counterpart only expresses GATA-4. The goal of the present study was to assess whether this reciprocal change in the expression of GATA factors might be relevant for predicting the prognosis of human adrenocortical neoplasms. Since human adrenal cortices express luteinizing hormone (LH/hCG) receptor and the gonadotropins are known to up-regulate GATA-4 in gonadal tumor cell lines, we also studied the expression of LH/hCG receptor. METHODS: We conducted a study on 13 non-metastasizing (NM) and 10 metastasizing/recurrent (MR) tumors obtained from a group of twenty-two adult and pediatric patients. The expression of GATA-4, GATA-6, and LH/hCG receptor (LHR) in normal and tumoral human adrenal cortices was analysed using reverse transcriptase-polymerase chain reaction (RT-PCR) complemented by dot blot hybridization. RESULTS: Messenger RNA for GATA-6 was detected in normal adrenal tissue, as well as in the totality of NM and MR tumors. GATA-4, by its turn, was detected in normal adrenal tissue, in 11 out of 13 NM tumors, and in 9 of the 10 MR tumors, with larger amounts of mRNA found among those presenting aggressive clinical behavior. Transcripts for LH receptor were observed both in normal tissue and neoplasms. A more intense LHR transcript accumulation was observed on those tumors with better clinical outcome. CONCLUSION: Our data suggest that the expression of GATA-6 in human adrenal cortex is not affected by tumorigenesis. GATA-4 expression is more abundant in MR tumors, while NM tumors express more intensely LHR. Further studies with larger cohorts are needed to test whether relative expression levels of LHR or GATA-4 might be used as prognosis predictors.

Abstract
Various cellular and molecular alterations of the cAMP pathway have been observed in adrenal Cushing syndrome. We recently reported the loss of cAMP-responsive element-binding protein (CREB) expression in the adrenocortical cancer cell line H295R. CREB is the major nuclear target of the cAMP pathway. This study therefore aimed to analyze the status of the CREB protein in various types of human adrenocortical tumors and normal fetal adrenal cortex. CREB protein status was studied by Western blotting in adrenocortical adenomas (AAs, n = 27) and adrenocortical carcinomas (ACs, n = 24). A decrease of CREB protein was noticed in the majority of the adrenocortical tumors. The dramatic decrease in CREB protein levels was more pronounced in ACs than in AAs. Levels of the phosphorylated form of CREB were also low in adrenocortical tumors, with a greater decrease in ACs than in AAs. EMSAs also showed decreases in the amounts of CREB- containing complexes in nuclear extracts from adrenocortical tumors. The secretory status of adenomas was strongly correlated with CREB levels, significantly lower in nonfunctioning AAs (n = 9) than in functioning AAs (n = 9). CREB levels, determined by Western blotting and immunohistochemistry, were very low in the fetal zone of human fetal adrenal cortex, whereas they were normal in the definitive zone. In tumors, adrenocortical cells in several zones were weakly immunohistochemically stained for CREB, whereas CREB was uniformly detected in nonendocrine cell nuclei (e.g. vascular cells, fibroblasts). These results suggest that the absence of CREB may be linked to the development of a highly aggressive tumor with a dedifferentiated benign (nonfunctioning AA) or malignant (AC) phenotype. These findings highlight the similarities between the normal human fetal adrenal gland and adrenal cancers previously observed in terms of parallelism in IGF-II production.

Abstract
The adrenal glands are a major source of steroid hormone biosynthesis. In normal physiology, the pituitary hormone corticotropin (ACTH) regulates the secretion of glucocorticoids via its G protein-coupled receptor (ACTHR), the product of the MC2R gene. Aldosterone is another major product of the adrenal gland; its regulation is controlled mainly by the renin-angiotensin system, although ACTH plays a role, too, especially under certain pathological conditions. The adrenal gland also secretes lesser amounts of androgens and intermediate metabolites of all these steroids. Unregulated secretion of any of these hormones can be caused by tumors, adrenocortical adenomas or carcinomas, and/or bilateral (or, rarely, unilateral) hyperplasia. Cortisol-producing hyperplasia of the adrenal glands is caused by two distinct syndromes, both of which have been directly or indirectly associated with protein kinase A signaling: (i) primary pigmented nodular adrenocortical disease (PPNAD) (a micronodular form of bilateral adrenal hyperplasia), either isolated (rarely) or in the context of Carney complex, is caused (in most cases) by mutations of the PRKAR1A gene; and (ii) ACTH-independent macronodular adrenal hyperplasia (AIMAH), or massive macronodular adrenal disease (MMAD), has been associated with aberrant (ectopic) expression, and presumably regulation, of various G protein-coupled receptors. AIMAH is a rare, sporadic condition affecting predominantly middle-aged men and women with an almost equal ratio (the latter in contrast to other forms of endogenous Cushing's syndrome). Some familial cases of AIMAH have also been described, and it appears that the pathophysiological phenomena underlying AIMAH may be present in the far more common, sporadic adrenocortical tumors and, perhaps, in the nodular growth detected in the adrenal glands of the elderly in the general population. Thus, the study of ectopic receptor expression and cAMP-dependent PKA activity in AIMAH may have wider implications for adrenal and, indeed, endocrine tumorigenesis.

Abstract
Adrenocortical carcinoma is a rare tumor that carries a very poor prognosis. Despite efforts to develop new therapeutic regimens to treat this disease, surgery remains the mainstay of treatment. Laboratory studies of adrenocortical cancers have revealed a wide variety of signaling pathways that can be altered in these neoplasms. Although ACTH signaling through adenylyl cyclase and protein kinase A is important for normal adrenal cellular physiology, there is evidence to suggest that this pathway may inhibit the growth of adrenocortical tumors, and that inactivation of the ACTH receptor may promote tumor formation. Although multiple signal transduction pathways are essential for normal adrenal growth and hormone secretion, efforts to identify events required for neoplastic transformation have met with limited success. Alterations that have frequently been observed in adrenocortical carcinoma include up-regulation of the IGF-II system, as well as mutations in TP53 and RAS. Current studies aim to elucidate the mechanisms of tumor growth by studying proproliferative signaling pathways, such as those involving Akt/PKB and the mitogen-activated protein kinases (MAPKs). Although studies of single pathways have been helpful in guiding investigations, new tools to study the integration and multiplicity of signaling pathways hold the hope of improved understanding of the signaling pathway alterations in adrenocortical cancer.
