Abstract
Background: Lung function is highly heritable and differs between the sexes throughout life. However, little is known about sex-differential genetic effects on lung function. We aimed to conduct the first genome-wide genotype-by-sex interaction study on lung function to identify genetic effects that differ between males and females. Methods: We tested for interactions between 7,745,864 variants and sex on spirometry-based measures of lung function in UK Biobank (N=303,612), and sought replication in 75,696 independent individuals from the SpiroMeta consortium. Results: Five independent single-nucleotide polymorphisms (SNPs) showed genome-wide significant (P<5x10 -8) interactions with sex on lung function, and 21 showed suggestive interactions (P<1x10 -6). The strongest signal, from rs7697189 (chr4:145436894) on forced expiratory volume in 1 second (FEV 1) (P=3.15x10 -15), was replicated (P=0.016) in SpiroMeta. The C allele increased FEV 1 more in males (untransformed FEV 1 β=0.028 [SE 0.0022] litres) than females (β=0.009 [SE 0.0014] litres), and this effect was not accounted for by differential effects on height, smoking or pubertal age. rs7697189 resides upstream of the hedgehog-interacting protein ( HHIP) gene and was previously associated with lung function and HHIP lung expression. We found HHIP expression was significantly different between the sexes (P=6.90x10 -6), but we could not detect sex differential effects of rs7697189 on expression. Conclusions: We identified a novel genotype-by-sex interaction at a putative enhancer region upstream of the HHIP gene. Establishing the mechanism by which HHIP SNPs have different effects on lung function in males and females will be important for our understanding of lung health and diseases in both sexes.

Abstract
Tumors strongly depend on their surrounding tumor microenvironment (TME) for growth and progression, since stromal elements are required to generate the optimal conditions for cancer cell proliferation, invasion, and possibly metastasis. Prostate cancer (PCa), though easily curable during primary stages, represents a clinical challenge in advanced stages because of the acquisition of resistance to anti-cancer treatments, especially androgen-deprivation therapies (ADT), which possibly lead to uncurable metastases such as those affecting the bone. An increasing number of studies is giving evidence that prostate TME components, especially cancer-associated fibroblasts (CAFs), which are the most abundant cell type, play a causal role in PCa since the very early disease stages, influencing therapy resistance and metastatic progression. This is highlighted by the prognostic value of the analysis of stromal markers, which may predict disease recurrence and metastasis. However, further investigations on the molecular mechanisms of tumor-stroma interactions are still needed to develop novel therapeutic approaches targeting stromal components. In this review, we report the current knowledge of the characteristics and functions of the stroma in prostate tumorigenesis, including relevant discussion of normal prostate homeostasis, chronic inflammatory conditions, pre-neoplastic lesions, and primary and metastatic tumors. Specifically, we focus on the role of CAFs, to point out their prognostic and therapeutic potential in PCa.

Abstract
Androgen receptor (AR) plays a pivotal role as a target for amplification/mutation in pathogenesis and tumor progression in prostate, and thus, controlling AR activity or expression might be a feasible therapeutic approach for the treatment of prostate cancer. Here, we report the novel mechanisms by which 18β-glycyrrhetinic acid (GA) targets AR to stimulate cell death in both hormone-responsive and -refractory prostate cancer cells. We found that miR-488, a tumor suppressive microRNA, was markedly induced by GA treatment, resulting in the down-regulation of AR expression and inhibition of cellular responses mediated by androgens. Moreover, GA not only suppressed the expression of androgen target genes (TMPRSS2, PSA, and NKX3.1), but also enhanced the suppressive effect of anti-androgens (bicalutamide and flutamide) on LNCaP cell growth. Our data further provides evidence that down-regulation of AR expression by GA may occur through transcriptional suppression at AR promoter region between - 1014 and - 829. Ectopic expression of SFR and E2F3α reversed the inhibitory effect of GA on AR promoter activity as well as protein expression, suggesting that GA may target transcription factors SRF and E2F3α to regulate AR expression. Taken together, our study provides new insights on AR regulation and GA as a potential therapeutic candidate for human prostate cancer.

Abstract
Vascular smooth muscle cell (SMC) phenotypic modulation contributes to the development of restenosis. A sorafenib-eluting stent was specifically designed to target SMC phenotypic modulation to inhibit in-stent restenosis in the present study. SMC contractile protein from the freshly isolated rat aorta was expressed at a high level, but its expression was dramatically reduced after SMCs were cultured in 10% FBS for 1 wk. After sorafenib treatment, SMC contractile protein expression was markedly upregulated. We further observed that Yes-associated protein (YAP) expression was attenuated after sorafenib treatment in a dose-dependent manner. Overexpression of YAP by lentivirus reversed the expression of sorafenib-induced SMC contractile protein and increased the expression of cyclin D. Mechanistically, sorafenib regulated the serum response factor-myocardin (SRF-Myocd) complex through competitive binding of YAP to Myocd and increased SRF binding to CArG-containing regions of SMC-specific contractile genes within intact chromatin, thereby controlling the activity of smooth muscle-specific gene transcription. In a rabbit carotid model, the sorafenib-eluting stent (SFES) dramatically inhibited in-stent restenosis and upregulated SMC contractile protein expression. Overexpression of YAP blocked the antirestenosis effect of SFES and repressed contractile smooth muscle-specific genes in vivo, indicating that SFES attenuated in-stent restenosis through YAP-mediated SMC phenotypic modulation. We demonstrated that SFES attenuated in-stent restenosis through YAP-mediated SMC phenotypic modulation. Targeting SMC phenotypic modulation by drug-eluting stent represents an attractive therapeutic approach for the treatment of occlusive vascular diseases.NEW & NOTEWORTHY In the present study, we demonstrated that sorafenib regulates smooth muscle cell (SMC) phenotypic modulation from a proliferative to a contractile state. Sorafenib induced a myocardin-serum response factor interaction and increased SMC contractile gene transcription through the Yes-associated protein pathway. Moreover, local delivery of sorafenib regulating SMC phenotypic modulation represents a promising strategy in the design of drug-eluting stents.

Abstract
Androgen signaling in prostate smooth muscle cells (pSMCs) is critical for the maintenance of prostate homeostasis, the alterations of which are a central aspect in the development of pathological conditions. Testosterone can act through the classic androgen receptor (AR) in the cytoplasm, eliciting genomic signaling, or through different types of receptors located at the plasma membrane for nongenomic signaling. We aimed to find evidence of nongenomic testosterone-signaling mechanisms in pSMCs and their participation in cell proliferation, differentiation, and the modulation of the response to lipopolysaccharide. We demonstrated that pSMCs can respond to testosterone by a rapid activation of ERK1/2 and Akt. Furthermore, a pool of ARs localized at the cell surface of pSMCs is responsible for a nongenomic testosterone-induced increase in cell proliferation. Through membrane receptor stimulation, testosterone favors a muscle phenotype, indicated by an increase in smooth muscle markers. We also showed that the anti-inflammatory effects of testosterone, capable of attenuating lipopolysaccharide-induced proinflammatory actions, are promoted only by receptors located inside the cell. We postulate that testosterone might perform prohomeostatic effects through intracellular-initiated mechanisms by modulating cell proliferation and inflammation, whereas some pathological, hyperproliferative actions would be induced by membrane-initiated nongenomic signaling in pSMCs.

Abstract
The prostate gland is a strictly androgen-dependent organ which is also the main target of infectious and inflammatory diseases in the male reproductive tract. Host defenses and immunity of the gland have unique features to maintain a constant balance between response and tolerance to diverse antigens. In this context, the effects of reproductive hormones on the male tract are thus complex and have just started to be defined. From the classical description of "the prostatic antibacterial factor," many host defense proteins with potent microbicidal and anti-tumoral activities have been described in the organ. Indeed, it has been proposed a central role for resident cells, that is, epithelial and smooth muscle cells, in the prostatic response against injuries. However, these cells also represent the target of the inflammatory damage, leading to the development of a Proliferative Inflammatory Atrophy-like process in the epithelium and a myofibroblastic-like reactive stroma. Available data on androgen regulation of inflammation led to a model of the complex control, in which the final effect will depend on the tissue microenvironment, the cause of inflammation, and the levels of androgens among other factors. In this paper, we review the current scientific literature about the inflammatory process in the gland, the modulation of host defense proteins, and the influence of testosterone on the resolution of prostatitis.
