The Effects of Caloric Restriction on Inflammatory Targets in the Prostates of Aged Rats. Int J Mol Sci 2024; 25:5236. [PMID: 38791274 PMCID: PMC11120753 DOI: 10.3390/ijms25105236] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2024] [Revised: 04/27/2024] [Accepted: 05/07/2024] [Indexed: 05/26/2024] Open
Abstract
Numerous animal models have demonstrated that caloric restriction (CR) is an excellent tool to delay aging and increase the quality of life, likely because it counteracts age-induced oxidative stress and inflammation. The aging process can affect the prostate in three ways: the onset of benign prostatic hyperplasia, prostatitis, and prostate cancer. In this study, we used 14 aged male Sprague Dawley rats, which were allocated into two groups, at the age of 18 months old. One group was fed ad libitum (a normal diet (ND)), and the other group followed a caloric restriction diet with a 60% decrease in intake. The rats were sacrificed at the age of 24 months. By immunohistochemical (IHC) and Western blot (WB) analyses, we studied the variations between the two groups in immune inflammation and fibrosis-related markers in aged prostate tissues. Morphological examinations showed lower levels of prostatic hyperplasia and fibrosis in the CR rats vs. the ND rats. The IHC results revealed that the prostates of the CR rats exhibited a lower immune proinflammatory infiltrate level and a reduced expression of the NLRP3 inflammasome pathway, together with significantly reduced expressions of mesenchymal markers and the profibrotic factor TGFβ1. Finally, by WB analysis, we observed a reduced expression of ERα, which is notoriously implicated in prostate stromal proliferation, and increased expressions of SOD1 and Hsp70, both exerting protective effects against oxidative stress. Overall, these data suggest that CR brings potential benefits to prostatic tissues as it reduces the physiological immune-inflammatory processes and the tissue remodeling caused by aging.

Abstract
C-type natriuretic peptide (CNP) exhibits anti-inflammatory activity besides its natriuretic and diuretic functions. The present study aimed to determine the anticancer and synergistic therapeutic activity of CNP against a 7,12-Dimethylbenz[a]anthracene (DMBA)/Croton oil-induced skin tumor mouse model. CNP (2.5 µg/kg body weight) was injected either alone and/or in combination with Cisplatin (CDDP) (2 mg/kg body weight) for 4 weeks. The dorsal skin tumor incidences/growth and mortality rate were recorded during the experimental period of 16 weeks. The serum C-reactive protein (CRP), and lactate dehydrogenase (LDH) levels, infiltrating mast cells, and AgNORs proliferating cells count were analyzed in control and experimental mice. Further, the expression profile of marker genes of proliferation, inflammation, and progression molecules were analyzed using Reverse transcriptase-polymerase chain reaction (RT-PCR)/quantitative PCR (qPCR), western blot, and immunohistochemistry. The DMBA/Croton oil-induced mice exhibited 100% tumor incidence. Whereas, CNP alone, CDDP alone, and CNP+CDDP combination-treated mice exhibited 58%, 46%, and 24% tumor incidence, respectively. Also, a marked reduction in the levels of serum CRP and LDH, the number of infiltrating mast cells count and AgNORs proliferating cells count were noticed in the mice skin sections. Further, a significant reduction in both mRNA and protein expression levels of proliferation, inflammation, and progression markers were noticed in CNP (p < 0.01), CDDP (p < 0.01), and CNP+CDDP combination (p < 0.001) treated mice, respectively. The results of the present study suggest that CNP has anticancer activity. Further, the CNP+CDDP treatment has more promising anticancer activity as compared with CNP or CDDP alone treatment, probably due to the synergistic antiproliferative and anti-inflammatory activities of CNP and CDDP.

Abstract
Mast cells are important components of the immune system, and they perform pro-inflammatory as well as anti-inflammatory roles in the complex process of immune regulation in health and disease. Because of their strategic perivascular localization, sensitivity and adaptability to the microenvironment, and ability to release a variety of preformed and newly synthesized effector molecules, mast cells perform unique functions in almost all organs. Additionally, Mast cells express a wide range of surface and cytoplasmic receptors which enable them to respond to a variety of cytokines, chemicals, and pathogens. The mast cell's role as a cellular interface between external and internal environments as well as between vasculature and tissues is critical for protection and repair. Mast cell interactions with different immune and nonimmune cells through secreted inflammatory mediators may also turn in favor of disease promoting agents. First and forefront, mast cells are well recognized for their multifaceted functions in allergic diseases. Reciprocal communication between mast cells and endothelial cells in the presence of bacterial toxins in chronic/sub-clinical infections induce persistent vascular inflammation. We have shown that mast cell proteases and histamine induce endothelial inflammatory responses that are synergistically amplified by bacterial toxins. Mast cells have been shown to exacerbate vascular changes in normal states as well as in chronic or subclinical infections, particularly among cigarette smokers. Furthermore, a potential role of mast cells in SARS-CoV-2-induced dysfunction of the capillary-alveolar interface adds to the growing understanding of mast cells in viral infections. The interaction between mast cells and microglial cells in the brain further highlights their significance in neuroinflammation. This review highlights the significant role of mast cells as the interface that acts as sensor and early responder through interactions with cells in systemic organs and the nervous system.

Abstract
Background The aging male population is at higher risk for benign prostatic hyperplasia (BPH) wherein increased proliferation of stromal and epithelial cells of the prostate is observed. In this study, we investigated the effect of cleistanthins A and B on the inhibition of testosterone-induced BPH in castrated rats. Methodology Male Wistar rats were divided into eight groups (n = 6) and surgical castration was performed. BPH was induced by the administration of testosterone propionate in corn oil at 5 mg/kg for four weeks. The control group received corn oil, and the model group received testosterone propionate. The standard treatment group received finasteride orally along with testosterone. Cleistanthins A and B at 0.3, 1, and 3 mg/kg were administered by oral gavage along with testosterone. After four weeks, rats were sacrificed, and prostates were weighed and assessed for histomorphological, inflammatory, apoptotic, and proliferative markers. Results Cleistanthins A and B decreased prostatic enlargement and histopathological abnormalities. Elevated serum dihydrotestosterone levels were lowered significantly in both the cleistanthin A and cleistanthin B groups compared to the BPH model group. Cleistanthins A and B significantly lowered the serum interleukin (IL)-1β and tumor necrosis factor-alpha inflammatory markers in the test groups. Western blot analysis revealed cleistanthin A downregulated the IL-6, signal transducer and activator of transcription 3/cyclin D1 signaling pathway. Both cleistanthins A and B upregulated the apoptotic markers caspase-3 and cleaved caspase-3, whereas the cell proliferation markers cyclin D1 and proliferating cell nuclear antigen were found to be downregulated. Conclusions Both cleistanthins A and B inhibited BPH in a rat model by apoptotic induction and impeded cell proliferation.

Abstract
Benign prostatic hyperplasia (BPH) is a commonly occurring disease in aging men. It involves cellular proliferation of stromal and glandular tissues leading to prostate enlargement. Current drug therapies show several adverse effects such as sexual dysfunctions and cardiovascular side effects. Therefore, there is a need to develop more effective medical treatment for BPH. In this regard, we aimed to identify genes which play a critical role in BPH. We have obtained the dataset of differentially expressed genes (DEGs) of BPH from NCBI GEO. DEGs were investigated in the context of their protein-protein interactions (PPI). Hub genes i.e. genes associated with BPH were scrutinized based on the topological parameters of the PPI network. These were analyzed for functional annotations, pathway enrichment analysis and transcriptional regulation. In total, 38 hub genes were identified. Hub genes such as transcription factor activator protein-1 and adiponectin were found to play key roles in cellular proliferation and inflammation. Another gene peroxisome proliferator activated receptor gamma was suggested to cause obesity, a common comorbidity of BPH. Moreover, our results indicated an important role of transforming growth factor-beta (TGF-β) signaling and smooth muscle cell proliferation which may be responsible for prostate overgrowth and associated lower urinary tract symptoms frequently encountered in BPH patients. Zinc finger protein Snai1 was the most prominent transcription factor regulating the expression of hub genes that participate in TGF-β signaling. Overall, our study has revealed significant hub genes that can be employed as drug targets to develop potential therapeutic interventions to treat BPH.

Abstract
Living at high altitudes and living with prostatic illness are two different conditions closely related to a hypoxic environment. People at high altitudes exposed to acute, chronic, or intermittent hypobaric hypoxia turn on several mechanisms at the system, cellular and molecular level to cope with oxygen atmosphere scarcity maintaining the oxygen homeostasis. This exposure affects the whole organism and function of many systems, such as cardiovascular, respiratory, and reproductive. On the other hand, malignant prostate is related to the scarcity of oxygen in the tissue microenvironment due to its low availability and high consumption due to the swift cell proliferation rates. Based on the literature, this similarity in the oxygen scarcity suggests that hypobaric hypoxia, and other common factors between these two conditions, could be involved in the aggravation of the pathological prostatic status. However, there is still a lack of evidence in the association of this disease in males at high altitudes. This review aims to examine the possible mechanisms that hypobaric hypoxia might negatively add to the pathological prostate function in males who live and work at high altitudes. More profound investigations of hypobaric hypoxia's direct action on the prostate could help understand this exposure's effect and prevent worse prostate illness impact in males at high altitudes.

Abstract
Intraurethral inoculation of mice with uropathogenic Escherichia coli (CP1) results in prostate inflammation, fibrosis, and urinary dysfunction, recapitulating some but not all of the pathognomonic clinical features associated with benign prostatic hyperplasia (BPH) and lower urinary tract symptoms (LUTS). In both patients with LUTS and CP1-infected mice, we observed increased numbers and activation of mast cells and elevated levels of prostate fibrosis. Therapeutic inhibition of mast cells using a combination of a mast cell stabilizer, cromolyn sodium, and the histamine 1 receptor antagonist cetirizine di-hydrochloride in the mouse model resulted in reduced mast cell activation in the prostate and significant alleviation of urinary dysfunction. Treated mice showed reduced prostate fibrosis, less infiltration of immune cells, and decreased inflammation. In addition, as opposed to symptomatic CP1-infected mice, treated mice showed reduced myosin light chain-2 phosphorylation, a marker of prostate smooth muscle contraction. These results show that mast cells play a critical role in the pathophysiology of urinary dysfunction and may be an important therapeutic target for men with BPH/LUTS.NEW & NOTEWORTHY LUTS-associated benign prostatic hyperplasia is derived from a combination of immune activation, extracellular matrix remodeling, hyperplasia, and smooth muscle cell contraction in prostates of men. Using a mouse model, we describe the importance of mast cells in regulating these multiple facets involved in the pathophysiology of LUTS. Mast cell inhibition alleviates both pathology and urinary dysfunction in this model, suggesting the potential for mast cell inhibition as a therapeutic that prevents and reverses pathology and associated symptomology.

Abstract
Background: The etiology of benign prostatic hyperplasia and prostate cancer are unknown, with ageing being the greatness risk factor. Methods: This new perspective evaluates the available interdisciplinary evidence regarding prostate ageing in terms of the cell biology of regulation and homeostasis, which could explain the timeline of evolutionary cancer biology as degenerative, inflammatory and neoplasm progressions in these multifactorial and heterogeneous prostatic diseases. Results: This prostate ageing degeneration hypothesis encompasses the testosterone-vascular-inflamm-ageing triad, along with the cell biology regulation of amyloidosis and autophagy within an evolutionary tumorigenesis microenvironment. Conclusions: An understanding of these biological processes of prostate ageing can provide potential strategies for early prevention and could contribute to maintaining quality of life for the ageing individual along with substantial medical cost savings.

Abstract
We investigated whether tryptase released from mast cells activated by prostate stromal cells (PSC) reacted with Trichomonas vaginalis (Tv) promoted the proliferation of PSC through protease- activated receptor 2 (PAR2). Conditioned medium of PSC was prepared by stimulating them with Tv (Trichomonad-conditioned medium (TCM)), and mast cell-conditioned medium were prepared by incubating them with TCM (mast cell-TCM (M-TCM)). Mast cells incubated with TCM migrated more efficiently and produced more β-hexosaminidase and tryptase. M-TCM containing tryptase increased the proliferation of PSC, while inhibition of tryptase decreased proliferation. Expression of signalling molecules such as PAR2, p-ERK, COX-2, 15d-PGJ2 and PPARγ, known to be involved in the tryptase-PAR2 pathway, increased in response to M-TCM, and blocking any of these signals decreased proliferation, indicating that tryptase-PAR2 signalling is involved in the proliferation of PSC. Inhibition of tryptase and PAR2 led to reduced expression of PAR2, p-ERK, COX-2, 15d-PGJ2 and PPARγ, while inhibition of ERK or COX-2 reduced the expression of COX-2, 15d-PGJ2 and PPARγ indicating that the tryptase-PAR2 pathway proceeds in the order p-ERK, COX-2, 15d-PGJ2 , and PPARγ. These results show that interaction between PSC stimulated with Tv and mast cells causes proliferation of PSC through the tryptase-PAR2 pathway.

Abstract
OBJECTIVE The association between asthma and benign prostatic hyperplasia (BPH) has rarely been explored. We investigated whether male asthmatic patients had an increased risk of BPH by conducting this retrospective nationwide population-based study. METHODS We utilized data derived from the National Health Insurance Research Database (NHIRD) in Taiwan. A total of 9778 male patients aged >40 years who were newly diagnosed with asthma between 2000 and 2006 were included in the asthma group. Male enrollees without asthma were selected as the non-asthma group from the same database. Both the groups were followed up until the end of 2013. We performed Cox proportional hazard regression analysis to estimate the risk of BPH and transurethral resection of the prostate (TURP) in the male patients with asthma compared with that in those without asthma. RESULTS The risk of BPH and TURP in the asthma group was 1.40-fold (95% confidence interval [CI] = 1.30-1.42) and 1.30-fold (95% CI= 1.31-1.50) higher than that in the non-asthma group, respectively, after adjusting for comorbidities, relevant medications and number of annual outpatient visits. CONCLUSIONS The male patients with asthma were found to have a higher risk of BPH than did those without asthma.

Abstract
Both subsets of MCs including MCTC (tryptase-positive, chymase-positive) and MCT (tryptase-positive, chymase-negative) are present in the testis and epididymis. Increased number of MCs, higher levels of MC-released tryptase in testis and seminal plasma of males with fertility problems, and promoting sperm motility in individuals with oligozoospermia after using MC blockers provide evidence that MCs may play a role in male infertility/subfertility disturbances. MC-released tryptase and histamine contribute to the fibrosis and may disrupt spermatogenesis. MCs not only influence the process of spermatogenesis but also have effects on the function of other testis-residing cells. MC-derived histamine may influence the steroidogenesis of Leydig cells by acting through H1R and H2R receptors. Additionally, the interaction between MC-released ATP and P2X receptors expressed on the peritubular cells may induce the production of the pro-inflammatory mediators by peritubular cells. Further investigations showed that MCs may be involved in the pathology of female infertility during implantation, pregnancy, and abortion. In the uterus, MCT subtype is abundant in myometrium and adjacent basal layer while MCTC subtype is distributed in all layers. MCs in response to hormones mainly estradiol and progesterone become activated and release a wide range of mediators including histamine, VEGF, proteases, and metalloproteinases (MMPs) that have a role in different stages of pregnancy. An increasing influx of MCs to the cervix during the pregnancy occurs that helps to the physiologic cervical ripening. While MMPs degrade the extracellular matrix (ECM), VEGF modulates neovascularization and histamine influences the embryo implantation. MC-derived histamine may have a positive effect during implantation due to its participation in tissue remodeling. MC proteases including tryptase and chymase activate the precursors of MMP2 and MMP9 to mediate ECM degradation during the physiologic menstrual cycle. There is a line of evidence that MCs have a role in abortion by releasing TNF-α.

Abstract
OBJECTIVE Considering the association of macrophage migration inhibitory factor with development of prostate diseases, this study aims to explore the effect and mechanism of macrophages (MAs) in inflammation and proliferation of benign prostate hyperplasia (BPH) cells. METHODS Totally 85 prostate tissues (75 from BPH patients and 10 from brain death patients) were collected for determination of biomarkers of T lymphocyte (CD4 and CD8), B lymphocyte (CD20) and MAs (CD68), as well as androgen receptor (AR) and CD40/CD40L. MAs stimulated by phorbol myristate acetate (PMA) were cultured with BPH cells (BPH-1), followed by AR inhibitor or anti-CD40 L antibody treatment. Proliferation and cell apoptosis were observed by MTT assay, colony formation assay and flow cytometer. Expressions of apoptotic related proteins and MAPK signaling pathway-related proteins were determined by qRT-PCR and Western blot. RESULTS BPH tissues had increased expressions of AR, CD40 and CD40 L, as well as elevated expressions of inflammation biomarkers (CD4, CD8, CD20 and CD68) in comparison to normal prostate tissues. MAs could increase the expressions of lymphocytes and inflammation biomarkers, in addition to promoting cell proliferation and inhibiting cell apoptosis. Cell proliferation and inflammation reaction could be attenuated by anti-CD40 L antibody and AR inhibitor in a concentration dependent manner through inhibiting the phosphorylation of JNK, ERK1/2 and p38. CONCLUSION MAs regulate AR and CD40/CD40L expression to promote the inflammation and proliferation as well as inhibiting apoptosis of BPH-1 cells through activation of the MAPK signaling pathway. This conclusion may provide a therapeutic strategy for BPH patients.

Can Botulinum Toxin A Still Have a Role in Treatment of Lower Urinary Tract Symptoms/Benign Prostatic Hyperplasia Through Inhibition of Chronic Prostatic Inflammation? Toxins (Basel) 2019; 11:toxins11090547. [PMID: 31546892 PMCID: PMC6784075 DOI: 10.3390/toxins11090547] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2019] [Revised: 09/12/2019] [Accepted: 09/17/2019] [Indexed: 11/16/2022] Open
Abstract
Patients with benign prostatic hyperplasia (BPH) can exhibit various lower urinary tract symptoms (LUTS) owing to bladder outlet obstruction (BOO), prostatic inflammation, and bladder response to BOO. The pathogenesis of BPH involves an imbalance of internal hormones and chronic prostatic inflammation, possibly triggered by prostatic infection, autoimmune responses, neurogenic inflammation, oxidative stress, and autonomic dysfunction. Botulinum toxin A (BoNT-A) is well recognized for its ability to block acetylcholine release at the neuromuscular junction by cleaving synaptosomal-associated proteins. Although current large clinical trials have shown no clinical benefits of BoNT-A for the management of LUTS due to BPH, BoNT-A has demonstrated beneficial effects in certain subsets of BPH patients with LUTS, especially in males with concomitant chronic prostatitis/chronic pelvic pain syndrome and smaller prostate. We conducted a review of published literature in Pubmed, using Botulinum toxin, BPH, BOO, inflammation, LUTS, and prostatitis as the key words. This article reviewed the mechanisms of BPH pathogenesis and anti-inflammatory effects of BoNT-A. The results suggested that to achieve effectiveness, the treatment of BPH with BoNT-A should be tailored according to more detailed clinical information and reliable biomarkers.

Curr Mol Med 2019; 19:605-619. [PMID: 31288722 DOI: 10.2174/1566524019666190709180146] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2019] [Revised: 06/14/2019] [Accepted: 06/14/2019] [Indexed: 12/27/2022]
Abstract
BACKGROUND Benign prostatic hyperplasia (BPH) and prostate cancer (PCa) are the most prevalent diseases in male population, implicated with fundamental differences between benign and malignant growth of prostate cells. An imbalance through a network of nervous, endocrine, and immune systems initiate a signal of altered growth from the brain to the prostate gland, leading to adverse effects such as inflammation. OBJECTIVE The aim of this study was to evaluate the gene expression of dopamine receptor family, COMT, and IL6 to identify novel correlations in BPH and PCa in both blood and tumor of the patients. METHODS Peripheral blood mononuclear cells from BPH (n= 30) and PCa (n= 30) patients, and prostate tumor tissues (n= 14) along with pathologically normal adjacent tissues (n= 14) were isolated, mRNA was extracted, and cDNA was synthesized, respectively. Quantitative real- time PCR was applied for DRD1- DRD5, COMT, and IL6 genes in all samples. RESULTS We found, for the first time, that the expression of COMT and IL6 genes were inversely correlated with the expression of DRD1 and DRD2 genes through the extent of differentiation of PCa from BPH condition. In addition, the PSA levels were correlated with the expression of DRD1 in BPH cases and DRD1, DRD4, DRD5, and IL6 in PCa cases. CONCLUSION Results implicate a potential cross- talk between the signaling pathways derived by IL6 cytokine and dopamine receptors in PCa. Thus, it seems promising to reassemble the consequent signaling pathways by adequate agonists and antagonists to help increase therapeutic efficacy.

Abstract
Vitamin D deficiency is especially prevalent in pregnant women and children. Our recent study demonstrated that vitamin D deficiency in early life disturbed testicular development. This study investigated the effects of vitamin D deficiency in early life on prostatic hyperplasia in middle-aged mice. In control group, dams and their male pups were fed with standard-chow diets. In VDD group, dams were fed with vitamin D deficient (VDD) diets throughout pregnancy and lactation. After weaning, male pups continued to be fed with VDD diets. As expected, prostate weight was elevated and prostatic hyperplasia was observed in VDD-fed mice. The number of prostatic Ki-67-positive epithelial cells, a proliferation marker, was increased in VDD-fed mice. Further analysis found that vitamin D deficiency promoted inflammatory infiltration and stromal fibrosis in prostate of middle-aged mice. Moreover, vitamin D deficiency activated NF-κB and up-regulated Il-6 mRNA in prostate of middle-aged mice. In addition, vitamin D deficiency activated prostatic STAT3, a proliferation pathway in middle-aged mice. Of interest, VDD-induced prostatic inflammation and hyperplasia were partially reversed when VDD diets was replaced with standard diets. These results provide evidence that vitamin D deficiency in early life promotes prostatic hyperplasia in middle-aged mice through exacerbating local inflammation.
