Pharmaceuticals (Basel) 2024; 17:1186. [PMID: 39338348 PMCID: PMC11435263 DOI: 10.3390/ph17091186] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2024] [Revised: 09/02/2024] [Accepted: 09/06/2024] [Indexed: 09/30/2024] Open
Abstract
Dehydroepiandrosterone and its sulfate are the most abundant steroids in humans. The metabolism of dehydroepiandrosterone can differ significantly depending on the organ or tissue and the subtype of steroid receptors expressed in it. For dehydroepiandrosterone, as a precursor of all steroid hormones, intracrine hormonal activity is inherent. This unique feature could be beneficial for the medicinal application, especially for the local treatment of various pathologies. At present, the clinical use of dehydroepiandrosterone is limited by its Intrarosa® (Quebec city, QC, Canada) prasterone) 6.5 mg vaginal suppositories for the treatment of vaginal atrophy and dyspareunia, while the dehydroepiandrosterone synthetic derivatives Triplex, BNN 27, and Fluasterone have the investigational status for the treatment of various diseases. Here, we discuss the molecular targets of dehydroepiandrosterone, which open future prospects to expand its indications for use. Dehydroepiandrosterone, as an oral drug, is surmised to have promise in the treatment of osteoporosis, cachexia, and sarcopenia, as does 10% unguent for skin and muscle regeneration. Also, 5-androstenediol, a metabolite of dehydroepiandrosterone, is a promising candidate for the treatment of acute radiation syndrome and as an immunostimulating agent during radiopharmaceutical therapy. The design and synthesis of new 5-androstenediol derivatives with increased bioavailability may lead to the appearance of highly effective cytoprotectors on the pharmaceutical market. The argumentations for new clinical applications of these steroids and novel insights into their mechanisms of action are discussed.

Life (Basel) 2024; 14:582. [PMID: 38792602 PMCID: PMC11122352 DOI: 10.3390/life14050582] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2024] [Revised: 04/18/2024] [Accepted: 04/28/2024] [Indexed: 05/26/2024] Open
Abstract
Pregnane neuroactive steroids, notably allopregnanolone and pregnenolone, exhibit efficacy in mitigating inflammatory signals triggered by toll-like receptor (TLR) activation, thus attenuating the production of inflammatory factors. Clinical studies highlight their therapeutic potential, particularly in conditions like postpartum depression (PPD), where the FDA-approved compound brexanolone, an intravenous formulation of allopregnanolone, effectively suppresses TLR-mediated inflammatory pathways, predicting symptom improvement. Additionally, pregnane neurosteroids exhibit trophic and anti-inflammatory properties, stimulating the production of vital trophic proteins and anti-inflammatory factors. Androstane neuroactive steroids, including estrogens and androgens, along with dehydroepiandrosterone (DHEA), display diverse effects on TLR expression and activation. Notably, androstenediol (ADIOL), an androstane neurosteroid, emerges as a potent anti-inflammatory agent, promising for therapeutic interventions. The dysregulation of immune responses via TLR signaling alongside reduced levels of endogenous neurosteroids significantly contributes to symptom severity across various neuropsychiatric disorders. Neuroactive steroids, such as allopregnanolone, demonstrate efficacy in alleviating symptoms of various neuropsychiatric disorders and modulating neuroimmune responses, offering potential intervention avenues. This review emphasizes the significant therapeutic potential of neuroactive steroids in modulating TLR signaling pathways, particularly in addressing inflammatory processes associated with neuropsychiatric disorders. It advances our understanding of the complex interplay between neuroactive steroids and immune responses, paving the way for personalized treatment strategies tailored to individual needs and providing insights for future research aimed at unraveling the intricacies of neuropsychiatric disorders.

Yao Y, Wang H, Yang Y, Jiang Z, Ma H. Dehydroepiandrosterone protects against oleic acid-triggered mitochondrial dysfunction to relieve oxidative stress and inflammation via activation of the AMPK-Nrf2 axis by targeting GPR30 in hepatocytes. Mol Immunol 2023; 155:110-123. [PMID: 36773597 DOI: 10.1016/j.molimm.2023.01.008] [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: 08/07/2022] [Revised: 01/14/2023] [Accepted: 01/21/2023] [Indexed: 02/11/2023]
Abstract
Fatty liver hemorrhage syndrome (FLHS) seriously threatens the health and performance of laying hens, and the occurrence and development of FLHS are closely related to oxidative damage and inflammation; thus, diets supplemental with activated substances to relive the oxidative stress and inflammation maybe effectively control the occurrences of FLHS. Dehydroepiandrosterone (DHEA) has beneficial effects in fat-reduction, anti-oxidation and anti-inflammation, and it was widely applied to alleviate multiple metabolic-related diseases; however, there are few reports on whether DHEA can prevent against metabolic-related diseases by modulating oxidative stress and inflammation, especially FLHS in laying hens. Herein, present study aimed to investigate the regulatory actions and potential molecular mechanism of DHEA on inflammation and oxidative stress triggered by oleic acid (OA)-stimulation in primary chicken hepatocytes and chicken hepatocellular carcinoma cell line (LMH). The results showed that DHEA significantly alleviated oxidative stress challenged by OA-stimulation via activation of AMP-activated protein kinase (AMPK)-nuclear factor-erythroid 2-related factor 2 (Nrf2) signaling pathway in hepatocytes, which led to relieving effect of DHEA on inflammatory by inhibiting mitogen-activated protein kinases (MAPKs) and nuclear factor κB (NF-κB) signaling pathways. Mechanistically, we found that the activation of AMPK-Nrf2 signaling pathway by DHEA treatment was mediated by G-protein coupled estrogen receptor (GPR30/GPER) in OA-stimulated hepatocytes. Further investigation found that DHEA activated the GPR30-mediated AMPK-Nrf2 signaling pathways to increase antioxidant capacity and inhibit mitochondrial reactive oxygen species (ROS) overproduction, which thereby inhibiting the activation of ROS-induced MAPK and NF-κB signaling pathways in OA-stimulated hepatocytes. Overall, these data demonstrated that DHEA attenuates the oxidative stress and inflammation triggered by OA-stimulation, and these beneficial effects of DHEA are achieved by activating the GPR30-mediated AMPK-Nrf2 signaling to prevent the impairment of mitochondrial function, and thereby inhibiting the activation of ROS-induced MAPK and NF-κB signaling pathways in hepatocytes. These results revealed the effects and mechanisms of DHEA on oxidative stress and inflammation, and also provide substantial information to support it as a potential nutritional supplement in preventing the occurrences of FLHS in laying hens and other metabolic-related diseases in animals and humans.

J Diabetes Investig 2023; 14:675-685. [PMID: 36811237 PMCID: PMC10119925 DOI: 10.1111/jdi.13997] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/05/2022] [Revised: 02/03/2023] [Accepted: 02/08/2023] [Indexed: 02/24/2023] Open
Abstract
AIMS This cross-sectional study assessed the association of serum dehydroepiandrosterone levels with the risk of diabetic retinopathy in patients with type 2 diabetes mellitus in China. MATERIALS AND METHODS Patients with type 2 diabetes mellitus were included in a multivariate logistic regression analysis to assess the association of dehydroepiandrosterone with diabetic retinopathy after adjusting for confounding factors. A restricted cubic spline was also used to model the association of serum dehydroepiandrosterone level with the risk of diabetic retinopathy and to describe the overall dose-response correlation. Additionally, an interaction test was conducted in the multivariate logistic regression analysis to compare the effects of dehydroepiandrosterone on diabetic retinopathy among age, sex, obesity status, hypertension, dyslipidemia, and glycosylated hemoglobin level subgroups. RESULTS In total, 1,519 patients were included in the final analysis. Low serum dehydroepiandrosterone was significantly associated with diabetic retinopathy in patients with type 2 diabetes mellitus after adjustment for confounding factors (odds ratio [quartile 4 vs quartile 1]: 0.51; 95% confidence interval: 0.32-0.81; P = 0.012 for the trend). Additionally, the restricted cubic spline indicated that the odds of diabetic retinopathy decreased linearly as the dehydroepiandrosterone concentration increased (P-overall = 0.044; P-nonlinear = 0.364). Finally, the subgroup analyses showed that the dehydroepiandrosterone level stably affected diabetic retinopathy (all P for interaction >0.05). CONCLUSIONS Low serum dehydroepiandrosterone levels were significantly associated with diabetic retinopathy in patients with type 2 diabetes mellitus, suggesting that dehydroepiandrosterone contributes to the pathogenesis of diabetic retinopathy.

Abstract
Allergic respiratory disease is a worldwide and increasingly prevalent health problem. Many researchers have identified complex changes in the microbiota of the respiratory and intestinal tracts in patients with allergic respiratory diseases. These affect immune response and influence the progression of disease. However, the diversity of bacterial changes in such cases make it difficult to identify a specific microorganism to target for adjustment. Recent research evidence suggests that common bacterial variations present in allergic respiratory disease are associated with immune disorders. This finding could lead to the discovery of potential therapeutic targets in cases of allergic respiratory disease. In this review, we summarize current knowledge of bacteria changes in cases of allergic respiratory disease, to identify changes commonly associated with immune disorders, and thus provide a theoretical basis for targeting therapies of allergic respiratory disease through effective modulation of key bacteria.

Abstract
Endometritis is persistent inflammation caused by bacteria, which can lead to infertility. Although traditional Chinese medicine (TCM) has been used to treat endometritis, the underlying mechanism is still unclear. Here, Baogong Decoction (BGD), a TCM compound, was used to treat mouse endometritis induced by Escherichia coli (E. coli), and then 16S rRNA sequencing and non-targeted metabolomics were used to investigate the change of uterine microbiota and metabolomes in serum and uterine after BGD treatment. Finally, the therapeutic effect of potential metabolites for treating mouse endometritis screened by combined omics analyses was verified using pathological model. The results showed that BGD treatment could effectively treat endometritis associated with the increasing relative abundance of Firmicutes, Bacteroides, Lactobacillus and Lactococcus, and the decreasing relative abundance of Cupriavidus and Proteobacteria. 133 and 130 metabolites were found to be potential biomarkers in serum and uterine tissue respectively. In serum and tissues, dehydroepiandrosterone (DHEA) and catechol were significantly increased in the BGD treatment versus the inflammation group. Results of combined omics analyses demonstrated that DHEA was positively correlated with changes in microbiota. Results of pathological model demonstrated that DHEA could cure endometritis effectively associated with the decreasing infiltration of inflammatory cells and expression of inflammatory factors in the uterus. In summary, our results demonstrated that BGD could cure endometritis in mice by modulating the structure of the uterine microbiota and its metabolites, in which DHEA may be one of the main components of the therapeutic effect of BGD.

Abstract
PURPOSE OF REVIEW This review updates recent findings about Escherichia coli O157:H7 virulence factors and its bovine reservoir. This Shiga toxin (Stx)-producing E. coli belongs to the Enterohemorrhagic E. coli (EHEC) pathotype causing hemorrhagic colitis. Its low infectious dose makes it an efficient, severe, foodborne pathogen. Although EHEC remains in the intestine, Stx can translocate systemically and is cytotoxic to microvascular endothelial cells, especially in the kidney and brain. Disease can progress to life-threatening hemolytic uremic syndrome (HUS) with hemolytic anemia, acute kidney failure, and thrombocytopenia. Young children, the immunocompromised, and the elderly are at the highest risk for HUS. Healthy ruminants are the major reservoir of EHEC and cattle are the primary source of human exposure. RECENT FINDINGS Advances in understanding E. coli O157:H7 pathogenesis include molecular mechanisms of virulence, bacterial adherence, type three secretion effectors, intestinal microbiome, inflammation, and reservoir maintenance. SUMMARY Many aspects of E. coli O157:H7 disease remain unclear and include the role of the human and bovine intestinal microbiomes in infection. Therapeutic strategies involve controlling inflammatory responses and/or intestinal barrier function. Finally, elimination/reduction of E. coli O157:H7 in cattle using CRISPR-engineered conjugative bacterial plasmids and/or on-farm management likely hold solutions to reduce infections and increase food safety/security.

Dehydroepiandrosterone exacerbates nigericin-induced abnormal autophagy and pyroptosis via GPER activation in LPS-primed macrophages. Cell Death Dis 2022; 13:372.

Abstract
As a widely acknowledged FDA-approved dietary supplement or over-the-counter medicines, dehydroepiandrosterone (DHEA) exerts anti-inflammatory and immunomodulatory function. Pyroptosis is an important form of programmed cell death (PCD), and which acts a key role in the body's anti-infection and inflammatory responses. But the effects and mechanisms of DHEA on pyroptosis remain unclear. Here, we found that DHEA inhibited the NLRP3 inflammasome components expression by blocking inflammatory signals in lipopolysaccharide (LPS)-primed macrophages, and prevented the bacterial toxin nigericin (Nig)-induced NLRP3 inflammasome assembly. However, DHEA exacerbated NLRP3-independent cell death in Nig-treated inflammatory macrophages. During this process, DHEA induced the abnormal autophagy, which reflected as the blocking of autophagic flux and the accumulation of autophagy receptor p62 (SQSTM1) protein. In addition, DHEA caused a burst of reactive oxygen species (ROS) and activated extracellular signal-regulated kinase (ERK) phosphorylation in LPS plus Nig-stimulated macrophages but not in LPS-treated macrophages. Mechanistically, the present study certified that the activation of G protein-coupled estrogen receptor (GPER) signal mediated the cell death induced by DHEA in Nig-stimulated inflammatory macrophages, as GPER specific inhibitor G15 alleviated the abnormal autophagy and ultimately prevented the gasdermin D (GSDMD)-mediated pyroptosis induced by DHEA. Collectively, DHEA can exacerbate Nig-induced abnormal autophagy and pyroptosis via activation of GPER in LPS-primed macrophages, which prompts us the potential application value of DHEA in anti-infection or anti-tumor immunity.

Abstract
Severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) is the cause of coronavirus infectious disease (COVID‐19) and has rapidly spread worldwide, causing serious problems to the healthcare systems of many countries and hundreds of thousand deaths. In this review we discuss data from the literature to understand whether the various districts of the male reproductive system may represent another vulnerable target for SARS‐CoV‐2. Studies were searched from electronic databases such as Google Scholar, PubMed, Scopus, and COVID‐19 specific databases such as LitCovid, until July 31, 2021. It appears that SARS‐CoV‐2 virus infection not only causes damage to the respiratory system, but could have a serious impact on the reproductive system of male patients modulating many physiological processes. Like some other infections, SARS‐CoV‐2 also leads to a worsening of semen quality and an increase in oxidative stress (OS) levels. However, due to the limited number of studies, it is unclear whether this deterioration in semen parameters is temporary or lasts over time. It is certainly important that patients' reproductive function is monitored after coronavirus infection to avoid problems in reproductive health in the future.

Abstract
The pathophysiology of COVID comprises an exaggerated pro-inflammatory response. Hypothalamic-pituitary-adrenal (HPA) axis has a crucial role in various inflammatory conditions and modulated immunological response. Limited evidence is available regarding the incidence and the effect of HPA dysfunction in COVID-19. Although the cortisol levels have only been estimated in a few studies, the dehydroepiandrosterone sulfate (DHEAS) release from the adrenal gland has not been explored yet. In this mini review, the authors discuss the role of dehydroepiandrosterone (DHEA) and DHEAS in the acute stress response and immunological modulation. Various effects of DHEAS have been demonstrated in different diseases. The specific inhibitory effect of DHEA on interleukin 6 (IL-6) could be of paramount importance in COVID-19. Further, DHEA supplementation has already been proposed in inflammatory conditions, like rheumatoid arthritis. DHEAS levels in COVID-19 may help to understand the HPA axis dysfunction as well as the possibility of repurposing DHEA as a drug for mitigating the pro-inflammatory COVID-19.

Abstract
Influenza B virus (IBV) is one of the most important human respiratory viruses: it causes approximately one-third of the global influenza-related disease burden each year. However, compared with the several pathogenicity-related molecular markers that have been identified for influenza A virus (IAV), little is known about potential IBV pathogenicity-related markers. Here, although the IBV strain B/Anhui-Tunxi/1528/2014 (AH1528/14) exhibited a more efficient replication ability in vitro and higher pathogenicity in vivo compared with IBV strain B/Anhui-Baohe/127/2015 (AH127/15), only three amino acids differences (HAA390E, NAN342D and PB1V212I) were observed among their full genomes. The contributions of each amino acid difference to the virus pathogenicity were further investigated. Compared with the wild type IBV virus rAH127, the recombinant virus harbouring a single substitution of HAA390E had a similar phenotype, whereas the recombinant virus harbouring PB1V212I replicated to a moderately higher titre in both MDCK cells and in mice. Notably, the virus harbouring NAN342D showed significantly better growth properties in MDCK cells and higher fatality rates in mice. In addition, the presence of NAN342D dramatically enhanced the viral neuraminidase activity. In conclusion, our study identified a novel IBV molecular marker, NAN342D, that could significantly increase the virulence of IBV in mice.

Zhu Z, Ling X, Zhou H, Zhang C, Yan W. Dexmedetomidine Attenuates Cellular Injury and Apoptosis in H9c2 Cardiomyocytes by Regulating p-38MAPK and Endoplasmic Reticulum Stress. DRUG DESIGN DEVELOPMENT AND THERAPY 2020; 14:4231-4243. [PMID: 33116411 PMCID: PMC7568428 DOI: 10.2147/dddt.s265970] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/03/2020] [Accepted: 09/19/2020] [Indexed: 12/18/2022]
Abstract
Background Myocardial ischaemia-reperfusion injury (IRI) has been confirmed to induce endoplasmic reticulum stress (ERS) when myocardial cell function continues to deteriorate to a certain degree. The clinical applications of effective tested strategies are sometimes inconsistent with the applications evaluated in experiments, although reasonable mechanisms and diverse signalling pathways have been broadly explored. Dexmedetomidine (DEX) has been shown to attenuate IRI of the heart in animal studies. This study aimed to determine whether DEX can protect injured cardiomyocytes under hypoxia/reoxygenation (H/R) at the cellular level and whether the mechanism is related to ERS and the p38 MAPK pathway. Methods H9c2 cells were subjected to H/R or thapsigargin (TG) to build a model. DEX or 4-PBA was added to the medium either 1 h or 24 h before modelling, respectively. Model parameters were determined by assessing cell viability and injury, which were measured by assessing cell counting kit-8 (CCK8), lactate dehydrogenase (LDH) release and flow cytometry results, and the expression of GRP78, CHOP and caspase-12. In addition, the protein expression of p38MAPK and p-p38MAPK was examined, and SB202190, a negative regulator, was also preincubated in medium. Results Compared to that of cells in the control group, the activity of cells in the H/R and TG groups was decreased dramatically, and the LDH concentration and proportion of apoptotic cells were increased. DEX could correspondingly reverse the changes induced by H/R or TG. Additionally, DEX effectively attenuated ERS defined as increased expression of GRP78, CHOP and caspase-12. Additionally, DEX could obviously depress the P38 MAPK phosphorylation and high p-p38 MAPK expression in the TG group, indicating DEX has a function similar to that of SB202190. Conclusion H/R injury in H9c2 cells can lead to abnormal ERS and apoptosis, as well as activation of the p38MAPK signalling pathway. DEX can protect cardiomyocytes by intervening in ERS, regulating p38MAPK and the downstream apoptotic signalling pathway.

Abstract
Although the treatment of multiple-injured patients has been improved during the last decades, sepsis and multiple organ failure (MOF) still remain the major cause of death. Following trauma, profound alterations of a large number of physiological systems can be observed that may potentially contribute to the development of sepsis and MOF. This includes alterations of the neuroendocrine and the immune system. A large number of studies focused on posttraumatic changes of the immune system, but the cause of posttraumatic immune disturbance remains to be established. However, an increasing number of data indicate that the bidirectional interaction between the neuroendocrine and the immune system may be an important mechanism involved in the development of sepsis and MOF. The aim of this article is to highlight the current knowledge of the neuroendocrine modulation of the immune system during trauma and sepsis.

Glucocorticoids Promote the Onset of Acute Experimental Colitis and Cancer by Upregulating mTOR Signaling in Intestinal Epithelial Cells. Cancers (Basel) 2020; 12:cancers12040945.

Abstract
The therapeutic effects of glucocorticoids on colitis and colitis-associated cancer are unclear. In this study, we investigated the therapeutic roles of glucocorticoids in acute experimental ulcerative colitis and colitis-associated cancer in mice and their immunoregulatory mechanisms. Murine acute ulcerative colitis was induced by dextran sulfate sodium (DSS) and treated with dexamethasone (Dex) at different doses. Dex significantly exacerbated the onset and severity of DSS-induced colitis and potentiated mucosal inflammatory macrophage and neutrophil infiltration, as well as cytokine production. Furthermore, under inflammatory conditions, the expression of the glucocorticoid receptor (GR) did not change significantly, while mammalian target of rapamycin (mTOR) signaling was higher in colonic epithelial cells than in colonic immune cells. The deletion of mTOR in intestinal epithelial cells, but not that in myeloid immune cells, in mice significantly ameliorated the severe course of colitis caused by Dex, including weight loss, clinical score, colon length, pathological damage, inflammatory cell infiltration and pro-inflammatory cytokine production. These data suggest that mTOR signaling in intestinal epithelial cells, mainly mTORC1, plays a critical role in the Dex-induced exacerbation of acute colitis and colitis-associated cancer. Thus, these pieces of evidence indicate that glucocorticoid-induced mTOR signaling in epithelial cells is required in the early stages of acute ulcerative colitis by modulating the dynamics of innate immune cell recruitment and activation.
