Abstract
Prostatic hyperplasia is very common in elderly men and is a typical disease that reduces quality of life. Histologically, hyperplasia of the prostate gland causes obstruction at the bladder outlet, resulting in symptoms such as a weak urine stream. Various factors have been considered to cause histological enlargement of the prostate, but the underlying cause is still unknown. The factors that cause prostate hyperplasia can be broadly classified into intrinsic and extrinsic ones. Extrinsic factors include things that we directly come into contact with such as bacteria and food. On the other hand, intrinsic factors are those that cause changes in functions originally provided in the body due to some cause, including extrinsic factors, such as chronic inflammation and an imbalance of sex hormones. A large number of reports have been made to date regarding the etiology of prostatic hyperplasia, although they have not yet clarified the fundamental cause(s). The various factors currently known should be outlined for future research. Should it be possible to prevent this highly prevalent prostatic hyperplasia which is mainly cause of dcreasing quality of life, there is no doubt that it would be a huge contribution to humanity.

Associations between Sex Hormones and Circulating Growth Differentiation Factor-15 in Male Patients with Major Depressive Disorder. Brain Sci 2021; 11:brainsci11121612. [PMID: 34942914 PMCID: PMC8699823 DOI: 10.3390/brainsci11121612] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2021] [Revised: 11/22/2021] [Accepted: 12/01/2021] [Indexed: 12/27/2022] Open
Abstract
The interaction between the endocrine system and inflammation is crucial pathogenesis of depression. Our study aimed at exploring the possible relationship between sex hormones and growth differentiation factor-15 (GDF-15), a common indicator of inflammation in male patients with major depressive disorder (MDD). Methods: GDF-15 levels of 121 male MDD patients were compared with 105 healthy subjects with the help of a Cobas 8000 automatic chemiluminescence immunoanalyzer. Results: (1) MDD patients showed higher GDF-15 levels, a lower testosterone (T) level and testosterone/estradiol ratio (T/E2 ratio) than healthy subjects (all p < 0.05). (2) Serum T levels and the T/E2 ratio were inversely associated with GDF-15 serum levels (all p < 0.05). (3) HAMD-24 scores were positively correlated with the levels of GDF-15 (p < 0.01), but not with T levels, estradiol (E2) levels, and the T/E2 ratio (all p > 0.05). Conclusion: The high level of GDF-15 was correlated with a low T/E2 ratio and T deficiency in male MDD patients. The above results demonstrate that up-regulation of serum GDF-15 and down-regulation of T and T/E2 ratio may be correlated with the occurrence and severity of depression. So, changing the level of GDF-15 by regulating the proportion of sex hormones may play a key role in the prognosis and treatment of depression.

Abstract
Benign prostatic hyperplasia is a major disease that affects the quality of life of middle-aged and older men. Although >70% of men aged >70 years have pathological benign prostatic hyperplasia, its pathogenesis and progression remain unclear. In this article, we reviewed the scientific literature on this condition and examined the development of lower urinary tract symptoms. Clinically, the weight of the prostate is not always proportional to the severity of the symptoms, and many factors can influence the progression of benign prostatic hyperplasia. Other than androgens, chronic inflammation can play an essential role in its development and the induction of symptoms, especially in symptomatic hyperplasia, because inflammatory cell infiltration is frequently observed in the prostate. Inflammation-induced changes in the prostate environment lead to changes in gene expression and subsequent chronicity of inflammation. It has been suggested that chronic asymptomatic prostatitis might be associated with changes in prostate structure and subsequent symptoms. In animal studies, the administration of anti-inflammatory drugs in rats with chronic prostatitis prevented the infiltration of inflammatory cells and increased the gland-to-stroma ratio. It is hoped that future research on the molecular biology of asymptomatic prostatitis might help to develop new therapeutic strategies for lower urinary tract symptoms associated with symptomatic prostatitis. Our conclusions provide a comprehensive insight into the prevalence and development of benign prostate hyperplasia and the treatment methods that can be used to treat it.

Abstract
Background Elevated levels of growth differentiation factor (GDF)-15 and reduced levels of testosterone have been linked to depressive disorder, but whether they are also linked to suicidal ideation in patients with depression is unclear. Methods This retrospective study involved 301 patients ≥22 years old hospitalized for depression between July 2018 and November 2020 at Renmin Hospital of Wuhan University, of whom 120 had suicidal ideation. Serum levels of GDF-15 and testosterone were compared between patients with or without suicidal ideation. Results GDF-15 levels were significantly higher among patients with suicidal ideation than among those without, regardless of whether testosterone levels were above or below the median of 314 ng/dL. In multivariate logistic regression involving all patients, serum GDF-15 level was associated with low testosterone level (P=0.001). Among patients with testosterone <314 ng/dL, an increase of 1 standard deviation in serum GDF-15 level translated to a 1.3-fold increase in the risk of suicidal ideation (P=0.007). This relationship was not observed in all population or patients with testosterone levels ≥314 ng/dL. Conclusion High serum GDF-15 level may be associated with an increased risk of suicidal ideation in patients with depression, and this association appears to be partly mediated by low testosterone levels.

Abstract
GDF-15 (growth differentiation factor 15) acts both as a stress-induced cytokine with diverse actions at different body sites and as a cell-autonomous regulator linked to cellular senescence and apoptosis. For multiple reasons, this divergent transforming growth factor-β molecular superfamily member should be better known to pulmonary researchers and clinicians. In ambulatory individuals, GDF-15 concentrations in peripheral blood are an established predictive biomarker of all-cause mortality and of adverse cardiovascular events. Concentrations upon admission of critically ill patients (without or with sepsis) correlate with organ dysfunction and independently predict short- and long-term mortality risk. GDF-15 is a major downstream mediator of p53 activation, but it can also be induced independently of p53, notably by nonsteroidal antiinflammatory agents. GDF-15 blood concentrations are markedly elevated in adults and children with pulmonary hypertension. Concentrations are also increased in chronic obstructive pulmonary disease, in which they contribute to mucus hypersecretion, airway epithelial cell senescence, and impaired antiviral defenses, which together with murine data support a role for GDF-15 in chronic obstructive pulmonary disease pathogenesis and progression. This review summarizes biological and clinical data on GDF-15 relevant to pulmonary and critical care medicine. We highlight the recent discovery of a central nervous system receptor for GDF-15, GFRAL (glial cell line-derived neurotrophic factor family receptor-α-like), an important advance with potential for novel treatments for obesity and cachexia. We also describe limitations and controversies in the existing literature, and we delineate research questions that must be addressed to determine whether GDF-15 can be therapeutically manipulated in other clinical settings.

Abstract
The growth inhibitory efficacy of methylseleninic acid (MSA) in prostate cancer cells has been documented extensively. However, our understanding of the immediate targets that are key to the growth inhibitory effects of MSA remains limited. Here, using multiple preclinical prostate cancer models, we demonstrated in vitro and in vivo that GDF15 is a most highly induced, immediate target of MSA. We further showed that knockdown of GDF15 mitigates MSA inhibition of cell proliferation and induction of apoptosis. Analysis of gene expression data from over 1000 primary and 200 metastatic prostate cancer samples revealed that GDF15 expression is decreased in metastatic prostate cancers compared to primary tumors and that lower GDF15 levels in primary tumors are associated with higher Gleason scores and shorter survival of the patients. Additionally, pathways that are negatively correlated with GDF15 levels in clinical samples are also negatively correlated with MSA treatment in cultured cells. Since most, if not all, of these pathways have been implicated in prostate cancer progression, suppressing their activities by inducing GDF15 is consistent with the anticancer effects of MSA in prostate cancer. Overall, this study provides support for GDF15 as an immediate target of MSA in prostate cancer cells.

Abstract
This study aimed to explore the association between growth differentiation factor-15 (GDF-15), a stress-induced factor, and sex hormones in male patients with coronary artery disease (CAD). In this study, we recruited 253 male patients with CAD and 205 male controls. Patients were divided into three groups in accordance with GDF-15 tertiles. Serum levels of GDF-15, testosterone, estradiol and other biochemical variables were measured. Serum levels of GDF-15 were significantly increased and serum testosterone and testosterone/estradiol ratio (T/E2 ratio) were significantly decreased in CAD patients compared with controls. Patients with high GDF-15 levels had lower testosterone (203.97, 95% CI 154.67-328.30 vs. 303.98, 95% CI 246.93-345.66; P = 0.001) and T/E2 ratio (8.82, 95% CI 5.77-11.41 vs. 11.07, 95% CI 7.91-14.32; P = 0.013). Correlation analyses showed that serum GDF-15 levels inversely correlated with testosterone levels (r = -0.339) and T/E2 ratio (r = -0.365) (both P < 0.001). In multivariate regression analyses, the association between GDF-15 and T/E2 ratio was maintained (B=-0.442, 95% CI -99.568 to -6.991, P = 0.015). Furthermore, in vitro studies showed a synergistic effect of testosterone and estradiol on GDF-15 secretion, and demonstrated that testosterone association with estradiol decreased GDF-15 secretion through androgen receptor/estrogen receptor-mediated pathways. Together, these results suggest that upregulation of GDF-15 in the presence of low and imbalanced sex hormone levels may contribute to CAD. Thus, restoring the balance of testosterone and estradiol may inhibit the effects of GDF-15 and serve as a promising therapeutic strategy for the treatment of CAD.

Abstract
Background There is a mutual interaction between inflammation and endocrine disorders in the development of coronary artery disease (CAD). Growth differentiation factor-15 (GDF-15) is associated with CAD, and the effects of testosterone on CAD as reported in literature have been considered as anti-atherosclerotic. The present study aimed to examine the possible association between serum GDF-15 and testosterone in male CAD patients. Methods GDF-15 and testosterone concentrations were determined in blood samples of 426 male patients with CAD and 220 male controls. Serum concentrations of hs-CRP, and other baseline characteristics were also measured. Results Serum levels of GDF-15 were higher in CAD patients when compared to controls, and testosterone concentrations were lower (p < 0.001). Patients with low testosterone levels had higher concentrations of GDF-15 (p < 0.001). In stratified analyses, inverse relations between GDF-15 levels and testosterone were noted for almost all strata, stratified by categories of hs-CRP, leukocytes, neutrophils, neutrophil to lymphocyte ratio, glucose, HDL-c, and LDL-c, and whether had hypertension, diabetes, and underwent percutaneous coronary intervention (PCI). Furthermore, in the linear regression models with bootstrap resampling with 1000 replications, high GDF-15 levels were independently associated with testosterone deficiency in male patients with CAD. Conclusions In male patients with CAD, high GDF-15 levels were associated with testosterone deficiency. These results support that upregulation of GDF-15 in the presence of low testosterone levels during CAD progression is a potential mechanism by which GDF-15 affects CAD.

Abstract
BACKGROUND Growth differentiation factor 15 (GDF15) has attracted much interest as a novel biomarker for epithelial ovarian carcinoma (EOC). Research focus has been directed at GDF15 as a diagnostic detection, while the prognostic determination of GDF15 in EOC patients remains to be clearly elucidated. The present study aimed to investigate GDF15 level relative to clinicopathological characters, chemoresponse, and clinical outcome of EOC patients. METHODS Serum from 122 patients with primary diagnosed EOC were analyzed for GDF15 and serum cancer antigen 125 (CA125). All cases were treated with debulking surgery and first-line chemotherapy, and samples were obtained just before debulking surgical treatment and first-line chemotherapy. Subsequently, clinical characteristics, responses to chemotherapy and progression-free survival (PFS) were recorded. RESULTS Increasing levels of serum GDF15 was significantly associated with FIGO stage and lymphonodus metastasis. GDF15 and CA125 detection are complementary in the diagnosis of EOC and can be simultaneously profiled. The chemo-resistant EOC patients (median, 1225.0 pg/mL) showed significantly higher GDF15 than chemo-sensitive patients (median, 824.2 pg/mL; P = 0.013). Highly expressed GDF15 was an independent negative prognostic indicator in the PFS (P = 0.026) of the 122 EOC cases in the multivariate analysis. Additionally, patients with high level of serum CA125 significantly associated with suboptimal (P = 0.043) debulking surgery. CONCLUSIONS Our results provide valuable evidence that GDF15 is related with first-line chemo-resistance, with highly expressed GDF15 being a strong and an independent indicator of shorter PFS in EOC patients.

Abstract
Benign prostatic hyperplasia (BPH) is a condition that greatly affects the quality of life of middle-aged and elderly men. Histopathologically, hyperplastic changes frequently occur in the prostate tissue of elderly men, the incidence of which has been reported to reach approximately 80% in men in their 70s. In clinical practice, approximately 25% of men with histologic BPH are assumed to experience lower urinary tract symptoms (LUTS) and receive some kind of treatment. In other words, there are some men with histologic BPH who do not exhibit LUTS. For that reason, many factors, such as the change in hormonal environment, the immune or autoimmune response, the alteration of gene expression, and so on, are thought to affect the onset and progression of LUTS in men with histologic BPH. One such factor that has long drawn attention is the presence of asymptomatic histological inflammation, which very often accompanies symptomatic BPH. Recent studies have suggested that asymptomatic histological inflammation causes repeated destruction, healing, and regeneration of the prostate tissue, leading to the enlargement of prostatic nodules, while at the same time causing stromal tissue-predominant remodeling of the prostate tissue, which can increase urination resistance and result in the condition changing from asymptomatic BPH to symptomatic BPH. In future, the biomolecular clarification of the significance of asymptomatic histological inflammation in the prostate tissue could help develop new treatment strategies for BPH accompanied by LUTS.

Background Prostate cancer (PCa) is the most common malignancy among men in the United States. Though highly sensitive, the often-used prostate-specific antigen (PSA) test has low specificity which leads to overdiagnosis and overtreatment of PCa. This paper presents results of a retrospective study that indicates that testing for macrophage inhibitory cytokine 1 (MIC-1) concentration along with the PSA assay could provide much improved specificity to the assay. Methods The MIC-1 serum level was determined by a novel p-Chip-based immunoassay run on 70 retrospective samples. The assay was configured on p-Chips, small integrated circuits (IC) capable of storing in their electronic memories a serial number to identify the molecular probe immobilized on its surface. The distribution of MIC-1 and pre-determined PSA concentrations were displayed in a 2D plot and the predictive power of the dual MIC-1/PSA assay was analyzed. Results MIC-1 concentration in serum was elevated in PCa patients (1.44 ng/ml) compared to normal and biopsy-negative individuals (0.93 ng/ml and 0.88 ng/ml, respectively). In addition, the MIC-1 level was correlated with the progression of PCa. The area under the receiver operator curve (AUC-ROC) was 0.81 providing an assay sensitivity of 83.3% and specificity of 60.7% by using a cutoff of 0.494 for the logistic regression value of MIC-1 and PSA. Another approach, by defining high-frequency PCa zones in a two-dimensional plot, resulted in assay sensitivity of 78.6% and specificity of 89.3%. Conclusions The analysis based on correlation of MIC-1 and PSA concentrations in serum with the patient PCa status improved the specificity of PCa diagnosis without compromising the high sensitivity of the PSA test alone and has potential for PCa prognosis for patient therapy strategies.

Abstract
INTRODUCTION Prostate cancer is the most common non-cutaneous malignancy diagnosed in men. Moving from histological observations since a long time, it has been recognized that innate and adaptive immunity actively participates in the pathogenesis, surveillance, and progression of prostate cancer. MATERIALS AND METHODS A PubMed and Web of Science databases search was performed for studies providing evidence on the roles of the innate and adaptive immunity during the development and progression of prostate cancer. CONCLUSIONS There are growing evidences that chronic inflammation is involved in the regulation of cellular events in prostate carcinogenesis, including disruption of the immune response and regulation of the tumor microenvironment. This review discusses the role played by the innate and adaptive immune system in the local progression of prostate cancer, and the prognostic information that we can currently understand and exploit.

Abstract
We aimed to determine plasma levels of growth and differentiation factor (GDF)-9 and GDF-15, and their possible association with bone turnover parameters and bone mineral density (BMD), in patients with polycystic ovary syndrome (PCOS). Forty-two obese PCOS women aged 25-35 years, 23 women with idiopathic hirsutism (IH) and 20 healthy controls matched for age and body mass index were enrolled. Anthropometric, metabolic and hormonal patterns, plasma GDF-9 and GDF-15 concentrations, bone turnover markers and BMD were measured. No significant differences were observed in bone turnover markers, BMD measurements, plasma GDF-9 and GDF-15 levels in subjects with PCOS compared with the other two groups. In the combined population of all three groups, GDF-15 concentrations were negatively correlated with osteocalcin (r = -0.317, p < 0.01). Analysis of PCOS patients showed a significant correlation of GDF-15 concentrations with age and homeostasis model assessment index (r = 0.319, p < 0.05, and r = 0.312, p < 0.05, respectively). In addition, GDF-15 concentrations were negatively correlated with osteocalcin (r = -0.395, p < 0.01) and positively correlated with urine deoxypyridinoline (r = 0.353, p < 0.05). GDF-9 did not correlate with bone markers and BMD measurements. In conclusion, plasma GDF-9 and GDF-15 levels as well as bone turnover markers and BMD measurements in subjects with PCOS (25-35 years of age) were comparable with those either in subjects with IH or in healthy controls with similar anthropometric and metabolic profiles. GDF-15 might be a marker of a crossregulation between bone and energy metabolism.

Abstract
Both benign prostatic hyperplasia (BPH) and prostate cancer (PCa) are frequent diseases in middle-aged to elderly men worldwide. While both diseases are linked to abnormal growth of the prostate, the epidemiological and pathological features of these two prostate diseases are different. BPH nodules typically arise from the transitional zone, and, in contrast, PCa arises from the peripheral zone. Androgen deprivation therapy alone may not be sufficient to cure these two prostatic diseases due to its undesirable side effects. The alteration of androgen receptor-mediated inflammatory signals from infiltrating immune cells and prostate stromal/epithelial cells may play key roles in those unwanted events. Herein, this review will focus on the roles of androgen/androgen receptor signals in the inflammation-induced progression of BPH and PCa.

Abstract
Benign prostatic hyperplasia (BPH) is the most common condition affecting men older than 50 years of age. It affects about 10 percent of men under the age of 40, and increases to about 80 percent by 80 years of age. BPH is a hyperplastic process of the fibromuscular stromal and glandular epithelial elements of the prostate. Aging and the presence of the functional testes are the two established risk factors for the development of BPH. The etiopathogenesis of BPH is still largely unresolved, but multiple partially overlapping and complementary theories have been proposed, all of which seem to be operative at least to some extent. This review is focused on recent progress in this area and on the growing consensus for the important mechanisms underlying the etiology and pathogenesis of BPH.

Abstract
Multifunctional macrophage inhibitory cytokine-1, MIC-1, is a member of the transforming growth factor-beta (TGF-beta) superfamily that plays key roles in the prenatal development and regulation of the cellular responses to stress signals and inflammation and tissue repair after acute injuries in adult life. The stringent control of the MIC-1 expression, secretion, and functions involves complex regulatory mechanisms and the interplay of other growth factor signaling networks that control the cell behavior. The deregulation of MIC-1 expression and signaling pathways has been associated with diverse human diseases and cancer progression. The MIC-1 expression levels substantially increase in cancer cells, serum, and/or cerebrospinal fluid during the progression of diverse human aggressive cancers, such as intracranial brain tumors, melanoma, and lung, gastrointestinal, pancreatic, colorectal, prostate, and breast epithelial cancers. Of clinical interest, an enhanced MIC-1 expression has been positively correlated with poor prognosis and patient survival. Secreted MIC-1 cytokine, like the TGF-beta prototypic member of the superfamily, may provide pleiotropic roles in the early and late stages of carcinogenesis. In particular, MIC-1 may contribute to the proliferation, migration, invasion, metastases, and treatment resistance of cancer cells as well as tumor-induced anorexia and weight loss in the late stages of cancer. Thus, secreted MIC-1 cytokine constitutes a new potential biomarker and therapeutic target of great clinical interest for the development of novel diagnostic and prognostic methods and/or cancer treatment against numerous metastatic, recurrent, and lethal cancers.

Abstract
BACKGROUND Chronic inflammation is commonly observed in benign prostate hyperplasia (BPH), and prostate tissue often contains increased inflammatory infiltrates, including T cells and macrophages. Cytokines are not only key mediators of inflammation but may also play important roles in the initiation and progression of BPH. METHODS In order to determine what cytokines might be involved in prostatic enlargement, expressed prostatic secretions (EPS) from ex vivo prostates were analyzed by human cytokine antibody microarray and ELISA. Prostate epithelial cells (PrEC) and prostate stromal cells (PrSC) were used for ELISA, proliferation, and Western blot assays. RESULTS Monocyte chemotactic protein-1 (MCP-1/CCL2) was one of the most elevated proteins in secretions from large prostate glands. PrSC were found to secrete MCP-1; Western blotting showed that both PrSC and PrEC express the MCP-1 receptor CCR2 which by RT-PCR was the CCR2b isoform. Proliferation assays showed that MCP-1 stimulates the proliferation of PrEC, but not PrSC, and that a specific MCP-1 antagonist (RS102895) suppressed this effect. Conditioned medium from PrSC stimulated the proliferation of PrEC as well, an effect completely inhibited by both RS102895 and a neutralizing anti-MCP-1 monoclonal antibody. The inflammatory cytokines interleukin (IL)-1 beta, interferon-gamma, and IL-2 enhanced the secretion of MCP-1 from PrEC and PrSC. In addition, MCP-1 levels in EPS correlated with mRNA levels of the macrophage marker CD68 in the same secretions. CONCLUSIONS The cytokine MCP-1, of apparent prostatic stromal cell origin, may play an important role in prostatic enlargement and BPH, and is a candidate biomarker for these pathologic processes.

Abstract
OBJECTIVES We have previously reported that the macrophage inhibitory cytokine-1 (MIC-1) gene is downregulated in human symptomatic benign prostatic hyperplasia. The aim of this study was to investigate the histologic changes and MIC-1 gene expression in the prostate of young nonbacterial prostatitis model (Y-NBP) and aging rats. METHODS A total of 35 Wistar male rats, 13 weeks old, were castrated and subjected to (a) castration alone for 14 days, (b) Y-NBP-14d (0.25 mg/2 mL/kg beta-estradiol injection for 14 days), or (c) Y-NBP-30d (beta-estradiol injection for 30 days). A total of 5 male rats, 10 months old, were also analyzed. We used 21 male rats, 13 weeks old, who had undergone sham surgery as the controls. The ventral lobes of the prostate were histologically examined with Masson's trichrome staining or immunostaining using an anti-macrophage antibody. The MIC-1 mRNA levels were quantitatively assessed using real-time reverse transcriptase-polymerase chain reaction. RESULTS The MIC-1 gene mRNA levels in the castration alone, Y-NBP-14d, and Y-NBP-30d rat prostates were greater than those in the control rats (P < .005). In contrast, those of the 10-month-old rats were lower than those of the controls (P = .0093). The mean stroma-to-epithelium ratio in the Y-NBP-30d rats, 10-month-old rats, and 13-week-old controls was 1.28, 0.26, and 0.10, respectively (Y-NBP-30d vs 10-month-old rats, P = .0008; 10-month-old vs 13-week-old rats, P = .001). The number of infiltrating macrophages in the Y-NBP-14d, Y-NBP-30d, and 10-month-old rats was greater than that of the 13-week-old controls (P < .001). CONCLUSIONS Castration causes induction of MIC-1 gene expression. Estradiol treatment has little effect on MIC-1 gene expression but causes a significant increase in the stroma-to-epithelium ratio. The aging rat prostate is more similar to human benign prostatic hyperplasia than is the Y-NBP model in light of MIC-1 gene expression and histologic changes.

Abstract
Benign prostatic hyperplasia (BPH) is the most common proliferative disease of the prostate of men in the United States. The histopathology of BPH strongly implicates local paracrine and autocrine growth factors and inflammatory cytokines in its pathogenesis. A complex milieu of growth-regulatory proteins includes members of the fibroblast, insulin-like, and transforming growth factor families. It appears that these proteins and downstream effector molecules, in addition to a variety of interleukins, are overexpressed in BPH and, working together, create a landscape of increased stromal and epithelial growth and mesenchymal transdifferentiation that leads to disease progression. Inflammation, commonly present in BPH, may contribute to tissue injury, and cytokines produced by inflammatory cells may serve to drive local growth factor production and angiogenesis in the tissues as a "wound healing" response. As we begin to unravel the precise mechanisms involved, new treatments for BPH aimed at these interacting pathways may emerge.

Abstract
Inflammation is a common finding in histologic prostate specimens obtained from aging men, and accumulating data suggest that inflammation may play an important role in the development of benign prostatic hyperplasia (BPH), and the development and progression of lower urinary tract symptoms (LUTS). Inflammatory processes may contribute to prostatic enlargement directly through stimulation of prostate growth, or, alternatively, through decreasing prostatic apoptosis. Additionally, inflammatory processes may impact other components of the urogenital tract, such as the bladder, and contribute to the LUTS that may be experienced both in the presence and in the absence of prostate enlargement. Current research therefore offers clues about converging inflammatory pathways which may be targeted to improve treatment of BPH and/or LUTS as well as identifying potential targets for prevention of these syndromes.

Abstract
Prostatitis, a histologic diagnosis, has evolved over the years to describe a clinical syndrome that was believed to be associated with prostatic inflammation. Similarly, benign prostatic hyperplasia (BPH), another histologic diagnosis, has evolved to describe a clinical syndrome believed to be associated with prostatic enlargement. Recent explorations of the interrelationships between these prostate-associated histologic and clinical conditions have generated much interest and excitement. This article describes these relationships and their impact on the management of, in particular, BPH.

Abstract
OBJECTIVE To investigate differences in gene expression in different zones of the prostate by microarray analyses, to better understand why aggressive tumours predominantly occur in the peripheral zone (PZ), whereas benign prostatic hyperplasia (BPH) occurs almost exclusively in the transition zone (TZ). MATERIALS AND METHODS Expression profiling of both prostate zones was done by microarray analysis. Reverse transcription-polymerase chain reaction (RT-PCR) of the top 18 genes confirmed the microarray analyses. RT-PCR with common cell-type markers indicated that the differential expression between the zones was not caused by an unequal distribution of different cell types. Primary stromal and epithelial prostate cells were used to study cell type expression in the 12 highest differentially expressed zonal-specific genes. RESULTS In all, 346 genes were identified as preferentially expressed in the TZ or PZ. A few of the TZ-specific genes, including ASPA, FLJ10970 and COCH, were also stroma-specific. Comparisons with other microarray studies showed that gene expression profiles of prostate cancer and BPH correlate with the expression profiles of the PZ and TZ, respectively. CONCLUSION Gene expression differs between the PZ and TZ of the prostate, and stromal-epithelial interactions might be responsible for the distinct zonal localization of prostate diseases.

Abstract
Recent advances on differently-expressed gene products and their functions during the progression from localized androgen-dependent states into androgen-independent and metastatic forms of prostate cancer are reported. The expression levels of numerous oncogenes and tumor suppressor genes in distinct prostatic cancer epithelial cell lines and tissues relative to normal prostate cells are described. This is carried out to identify the signaling elements that are altered during the initiation, progression and metastatic process of prostate cancer. Additional information on the interactions between certain deregulated signaling pathways such as androgen receptor (AR), estrogen receptors, epidermal growth factor receptor (EGFR), hedgehog and Wnt/beta-catenin cascades in controlling the proliferation, survival and invasion of tumor prostate epithelial cells during the disease progression is described. The emphasis is on the critical functions of the AR and EGF-EGFR systems at all stages during prostate carcinogenesis. Of therapeutic interest, new strategies for the diagnosis and treatment of localized and metastatic forms of prostate cancer by targeting multiple tumorigenic signaling elements are also reported.

Abstract
Proteomic analysis of formalin-fixed paraffin-embedded (FFPE) tissue would enable retrospective biomarker investigations of this vast archive of pathologically characterized clinical samples that exist worldwide. These FFPE tissues are, however, refractory to proteomic investigations utilizing many state of the art methodologies largely due to the high level of covalently cross-linked proteins arising from formalin fixation. A novel tissue microdissection technique has been developed and combined with a method to extract soluble peptides directly from FFPE tissue for mass spectral analysis of prostate cancer (PCa) and benign prostate hyperplasia (BPH). Hundreds of proteins from PCa and BPH tissue were identified, including several known PCa markers such as prostate-specific antigen, prostatic acid phosphatase, and macrophage inhibitory cytokine-1. Quantitative proteomic profiling utilizing stable isotope labeling confirmed similar expression levels of prostate-specific antigen and prostatic acid phosphatase in BPH and PCa cells, whereas the expression of macrophage inhibitory cytokine-1 was found to be greater in PCa as compared with BPH cells.

Abstract
A contaminant protein complex found in pharmaceutical urinary human chorionic gonadotrophin preparations is reported to have anti-human immunodeficiency virus-associated Kaposi's sarcoma activity. The aim of this study was to isolate and characterize this protein complex by proteomic approaches. Size exclusion chromatography was used in the isolation of these human chorionic gonadotrophin-associated fragments. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis showed the presence of a protein complex that dissociated into two protein bands under reducing conditions. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry of this complex showed three polypeptides at approximately 6.2, 11.4, and 15.8 kDa. Peptide mass mapping and N-terminal amino acid sequencing identified two polypeptides as metabolites of placental transforming growth factor-beta (11.4 kDa) and bikunin (15.8 kDa). Subsequent matrix-assisted laser desorption/ionization time-of-flight mass spectrometric analysis of the anti-human immunodeficiency virus-associated Kaposi's sarcoma active preparations CG-10 (Sigma), Pregnyl (Organon), and Profasi (Serono) revealed the presence of metabolites of placental transforming growth factor-beta in all three; no other non-human chorionic gonadotrophin-related protein species were observed in these preparations. Our findings present evidence that urinary human chorionic gonadotrophin preparations are contaminated with metabolites of placental transforming growth factor-beta, which may have transforming growth factor-beta agonist actions, and metabolites of bikunin, which is a protease inhibitor. In combination these molecules may be responsible for the anti-human immunodeficiency virus-associated Kaposi's sarcoma activity demonstrated for these urinary human chorionic gonadotrophin preparations.

PURPOSE Our previous DNA microarray analyses revealed that the macrophage inhibitory cytokine-1 (MIC-1) gene was significantly down-regulated in symptomatic benign prostatic hyperplasia (BPH) samples. We compared the histopathological features of inflammatory changes in prostate adenoma tissues from individuals with symptomatic and asymptomatic (histological only) BPH using MIC-1 mRNA levels. MATERIALS AND METHODS Prostate adenoma tissues were obtained from 25 patients who underwent transurethral prostatectomy to relieve lower urinary tract symptoms due to BPH and 6 patients with bladder cancer who underwent cystoprostatectomy due to bladder cancer. Inflammatory changes in the prostate were examined histopathologically and immunohistochemically, and classified according to the consensus classification system of the Chronic Prostatitis Collaborative Research Network and International Prostatitis Collaborative Network advocated in 2001 with some modification. MIC-1 mRNA was assessed quantitatively by real-time reverse transcriptase-polymerase chain reaction. RESULTS MIC-1 gene down-regulation was observed in 16 of 25 symptomatic BPH samples (64.0%), whereas MIC-1 mRNA was high in 6 of 6 prostate adenoma samples from patients with bladder cancer (p = 0.0006). MIC-1 gene down-regulation correlated with the grade of glandular/ periglandular inflammatory changes with statistical significance (p = 0.0387). MIC-1 gene down-regulation was found in only 1 of 7 BPH samples with a glandular predominant pattern, whereas it was found in 15 of 24 BPH samples with a mixed type or stromal predominant pattern (p = 0.0373). CONCLUSIONS Gland destruction by inflammatory infiltrates, followed by replacement of the stromal component in symptomatic BPH may be induced by the down-regulation of the MIC-1 gene.
