Abstract
Extracellular nucleotides and nucleosides are crucial signalling molecules, eliciting diverse biological responses in almost all organs and tissues. These molecules exert their effects by activating specific nucleotide receptors, which are finely regulated by ectonucleotidases that break down their ligands. In this comprehensive review, we aim to elucidate the relevance of extracellular nucleotides as signalling molecules in the context of smooth muscle contraction, considering the modulatory influence of ectonucleotidases on this intricate process. Specifically, we provide a detailed examination of the involvement of extracellular nucleotides in the contraction of non-vascular smooth muscles, including those found in the urinary bladder, the airways, the reproductive system, and the gastrointestinal tract. Furthermore, we present a broader overview of the role of extracellular nucleotides in vascular smooth muscle contraction.

Abstract
P2 purinergic receptors are involved in the normal function of the kidney, bladder, and prostate via signaling that occurs in response to extracellular nucleotides. Dysregulation of these receptors is common in pathological states and often associated with disease initiation, progression, or aggressiveness. Indeed, P2 purinergic receptor expression is altered across multiple urologic disorders including chronic kidney disease, polycystic kidney disease, interstitial cystitis, urinary incontinence, overactive bladder syndrome, prostatitis, and benign prostatic hyperplasia. P2 purinergic receptors are likewise indirectly associated with these disorders via receptor-mediated inflammation and pain, a common characteristic across most urologic disorders. Furthermore, select P2 purinergic receptors are overexpressed in urologic cancer including renal cell carcinoma, urothelial carcinoma, and prostate adenocarcinoma, and pre-clinical studies depict P2 purinergic receptors as potential therapeutic targets. Herein, we highlight the compelling evidence for the exploration of P2 purinergic receptors as biomarkers and therapeutic targets in urologic cancers and other urologic disease. Likewise, there is currently optimism for P2 purinergic receptor-targeted therapeutics for the treatment of inflammation and pain associated with urologic diseases. Further exploration of the common pathways linking P2 purinergic receptor dysregulation to urologic disease might ultimately help in gaining new mechanistic insight into disease processes and therapeutic targeting.

Purinergic smooth muscle contractions in the human prostate: estimation of relevance and characterization of different agonists. Naunyn Schmiedebergs Arch Pharmacol 2021; 394:1113-1131. [PMID: 33427927 PMCID: PMC8208936 DOI: 10.1007/s00210-020-02044-4] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2020] [Accepted: 12/20/2020] [Indexed: 12/19/2022]
Abstract
Non-adrenergic prostate smooth muscle contractions may account for the limited effectiveness of α1-adrenoceptor antagonists, which are the first-line option for medical treatment of voiding symptoms suggestive of benign prostatic hyperplasia. In non-human prostates, purinergic agonists induce contractions reaching similar magnitudes as α1-adrenergic contractions. However, evidence for the human prostate is highly limited, and pointed to much weaker purinergic contractions. Here, we examined contractions of different purinergic agonists in human prostate tissues. Tissues were obtained from radical prostatectomy. Contractions were studied in an organ bath, and expression of purinergic receptors was studied by RT-PCR. Electric field stimulation (EFS)–induced contractions amounted to 104% of KCl-induced contractions (95% CI: 84–124%). From all tested agonists, only ATP induced concentration-dependent contractions, reaching an average maximum of 18% (12–24%) of KCl. Maximum tensions following application of other agonists averaged to 7.1% of KCl for α,β-methylene-ATP (1.8–12.4%), 3.9% for β,γ-methylene-ATP (2.0–5.4%), 3.1% for 2-methylthio-ATP (− 0.1–6.3%), and 5.1% for ATPγS (1.0–9.2%). Responses were not affected by the P2X antagonist NF023 or the P2Y antagonist PPADS. mRNA expression of P2X1-4 correlated with expression of a marker for catecholaminergic nerves, although neither ATP, NF023, nor PPADS changed EFS-induced contractions. Correlation between expression of receptors and the smooth muscle marker calponin was not observed. Our findings point to a low relevance of purinergic contractions in the human prostate, compared to other contractile stimuli in the human prostate and compared to purinergic contractions in non-human prostates. Purinergic contractions in the human prostate are not sensitive to NF023 or PPADS.

Onvansertib, a polo-like kinase 1 inhibitor, inhibits prostate stromal cell growth and prostate smooth muscle contraction, which is additive to inhibition by α 1-blockers. Eur J Pharmacol 2020; 873:172985.

Abstract
Prostate smooth muscle contraction and prostate enlargement contribute to lower urinary tract symptoms suggestive of benign prostatic hyperplasia. Recent evidence demonstrated that inhibitors for polo-like kinases (PLKs) inhibit smooth muscle contraction of human prostate tissues. However, their additive effects to α1-blockers, and effects on prostate growth are unknown. Here, we examined effects of a novel and highly selective PLK1 inhibitor, onvansertib on prostate smooth muscle contraction alone and in combination with α1-blockers, and on proliferation and viability of prostate stromal cells (WPMY-1). Prostate tissues were obtained from radical prostatectomy. Contractions were studied in an organ bath. Proliferation and viability were assessed by plate colony, EdU, and CCK-8 assay. Electric field stimulation (EFS)-induced contractions of human prostate tissues were inhibited to 34% by 100 nM and 1 μM onvansertib at 32 Hz, and to 48% and 47% by the α1-blockers tamsulosin and silodosin. Combination of onvansertib with tamsulosin or silodosin further reduced EFS-induced contractions in comparison to α1-blockers alone (59% and 61% respectively), and to onvansertib alone (68% for both). Noradrenaline-, phenylephrine-, methoxamine-, endothelin-1-, and ATP-induced contractions were inhibited by onvansertib (100 nM) to similar extent. Viability and proliferation of WPMY-1 cells were reduced in a concentration- and time-dependent manner (24-72 h, 10-100 nM). Onvansertib inhibits neurogenic, adrenergic, and endothelin-1- and ATP-induced contractions of human prostate smooth muscle, and proliferation of stromal cells. Contractions are reduced not more than 50% by α1-blockers. Combination of α1-blockers with onvansertib provides additive inhibition of prostate contractions.

Non-Adrenergic, Tamsulosin-Insensitive Smooth Muscle Contraction is Sufficient to Replace α 1 -Adrenergic Tension in the Human Prostate. Prostate 2017; 77:697-707.

Abstract
BACKGROUND Lower urinary tract symptoms (LUTS) suggestive of benign prostatic hyperplasia may be caused by prostate smooth muscle contraction. Although α1 -blockers may improve symptoms by prostate smooth muscle relaxation, their efficacy is limited. This may be explained by non-adrenergic mediators causing contraction in parallel to α1 -adrenoceptors. However, little is known about the relevance and cooperative actions of non-adrenergic mediators in the prostate. METHODS Prostate tissues were obtained from radical prostatectomy (n = 127 patients). Contractile responses were studied in an organ bath. RESULTS Endothelin-1 and noradrenaline induced contractions of similar magnitude (116 ± 23 and 117 ± 18% of KCl-induced contractions). Endothelin-2- and -3-induced maximum contractions of 63 ± 8.6 and 71 ± 19% of KCl, while contractions by the thromboxane analog U46619 amounted up to 63 ± 9.4%. Dopamine-induced contractions averaged to 22 ± 4.5% of KCl, while maximum contractions by serotonin, histamine, and carbachol stayed below 10% of KCl-induced. While noradrenaline-induced contractions were inhibited by tamsulosin (300 nM), endothelin-1-, -2-, or -3-induced contraction were not. No additive effects were observed if endothelins and noradrenaline were applied consecutively to the same samples. If endothelin-1 was applied after U46619, resulting tension (172 ± 43% of KCl) significantly exceeded noradrenaline-induced contraction. Tensions following combined application of endothelin-2 or -3 with U46619 stayed below noradrenaline-induced contractions. Tension following combined application of all three endothelins with U46619 resembled maximum noradrenaline-induced tone. CONCLUSIONS Contractions following concomitant confrontation of human prostate tissue with noradrenaline and endothelin-1 are not additive. Endothelin-1 is sufficient to induce a smooth muscle tone resembling that of noradrenaline. This may replace lacking α1 -adrenergic tone under therapy with α1 -blockers, explaining the limited efficacy of α1 -blockers in LUTS treatment. Contractions by thromboxane and endothelin-1 may be additive, and may exceed α1 -adrenergic tone. Prostate 77:697-707, 2017. © 2017 Wiley Periodicals, Inc.

Abstract
Children with acute hematogenous osteomyelitis (AHO) demonstrate a broad spectrum of clinical manifestations, ranging from mild to severe. Several advances have been achieved in the study of host immune response to acute invasive Staphylococcus aureus infections through gene expression analysis. However, previous research has neither attempted to evaluate the response of children with AHO specific to Methicillin-resistant Staphylococcus aureus (MRSA) nor to correlate gene expression with clinical phenotype. Study objective was to correlate gene expression of children with AHO due to MRSA with clinical severity of illness. Whole blood samples were obtained in Tempus tubes from 12 children with osteomyelitis once cultures obtained directly from the site of infection confirmed to be positive for MRSA. Using an Illumina platform and a systems-wide modular analysis, microarray findings from ten of these children were compared to that of nine healthy (age, ethnicity and gender) matched controls and correlated with clinical severity of illness. Children with AHO from MRSA demonstrated over-expression of innate immunity with respect to neutrophil activity, coagulation, inflammatory response, and erythrocyte development. Concurrently, these children demonstrated under-expression of adaptive immunity with respect to lymphocyte activation and activity of T-cell, cytotoxic or NK cell, and B-cell lines. Three over-expressed genes, P2RX1, SORT1, and RETN, and two under-expressed genes, LOC641788 and STAT 4, were significantly correlated with severity of illness. STAT 4 showed the strongest correlation (R2 = –0.83). STAT4 downregulation could potentially explain under-expression of genes related to adaptive immunity in this cohort of patients with AHO. This study identified specific genes which correspond to disease severity during the early hospitalization of children with AHO from MRSA. Pattern recognition of this combination of genes could help to identify in the future severe clinical phenotypes before the disease is fully manifest and direct appropriate attention and resources to those children.
