Abstract
A previous study using miRNA sequencing revealed that exposure to a mixture of phthalates during pregnancy and lactation dysregulated rno-miR-184 and rno-miR-141-3p in the ventral prostate (VP) of offspring. Here, rno-miR-184 and rno-miR-141-3 expressions were obtained by RT-qPCR in the VP of F1 males as well as in F2 offspring, aiming to establish a relationship with possible oncogenic targets through in silico analyses with multigenerational approach. Additionally, some targets were measured by western blots to highlight a possible relationship between the deregulated miRNAs and some of their targets. VP samples from rats exposed to a mixture of phthalates maternally during pregnancy and lactation (GD10 to PND21-F1) and VP from offspring (F2) were examined. The phthalate mixture at both concentrations (20 μg and 200 mg/kg/day) increased the expression of both miRNAs in the F1 (PND22 and 120) and F2 (descendants of F1-treated males) prostate. Target prediction analysis revealed that both microRNAs are responsible for modulating the expression and synthesis of 40 common targets. A phthalate target association analysis and the HPA database showed an interesting relationship among these possible miRNAs modulated targets with prostate adenocarcinoma and other oncogenic processes. Western blots showed alteration in P63, P53, WNT5, and STAT3 expression, which are targeted by the miRNAs, in the VP of F1/F2 males. The data draw attention to the epigenetic modulation in the prostate of descendants exposed to phthalates and adds to one of the few currently found in the literature to point to microRNAs signature as biomarkers of exposure to plasticizers.

Abstract
As the second leading cause of death for cancer among men worldwide, prostate cancer (PCa) prevention and detection remain a critical challenge. One aspect of PCa research is the identification of common environmental agents that may increase the risk of initiation and progression of PCa. Endocrine disrupting chemicals (EDCs) are strong candidates for risk factors, partially because they alter essential pathways for prostate gland development and oncogenesis. Phthalates correspond to a set of commercially used plasticizers that humans are exposed to ubiquitously. Here, we show that maternal exposure to a phthalate mixture interferes with the expression profile of mRNA and proteins in the ventral prostate of offspring and increases the susceptibility to prostate adenocarcinomas in aged animals. The data highlight Ubxn11, Aldoc, Kif5c, Tubb4a, Tubb3, Tubb2, Rab6b and Rab3b as differentially expressed targets in young and adult offspring descendants (PND22 and PND120). These phthalate-induced targets were enriched for pathways such as: dysregulation in post-translational protein modification (PTPM), cell homeostasis, HSP90 chaperone activity, gap junctions, and kinases. In addition, the Kif5c, Tubb3, Tubb2b and Tubb4a targets were enriched for impairment in cell cycle and GTPase activity. Furthermore, these targets showed strong relationships with 12 transcriptional factors (TF), which regulate the phosphorylation of eight protein kinases. The correlation of TF-kinases is associated with alterations in immune system, RAS/ErbB/VEGF/estrogen/HIF-1 signaling pathways, cellular senescence, cell cycle, autophagy, and apoptosis. Downregulation of KIF5C, TUBB3 and RAB6B targets is associated with poor prognosis in patients diagnosed with adenocarcinoma. Collectively, this integrative investigation establishes the post-transcriptional mechanisms in the prostate that are modulated by maternal exposure to phthalate mixture during gestation and lactation.

Abstract
Western diet (WD), abundant in saturated fats and simple carbohydrates, has been associated with the development of prostate diseases. In addition, 2,4-dichlorophenoxyacetic acid (2,4-D), an herbicide used in agricultural and non-agricultural settings, may interfere with the endocrine system impacting reproductive health. The association of both factors is something common in everyday life, however, there are no relevant studies associating them as possible modulators of prostatic diseases. This study evaluated the action of the herbicide 2,4-D on the postnatal development of the prostate in mice fed with WD. Male C57Bl/6J mice received simultaneously a WD and 2,4-D at doses of 0.02, 2.0, or 20.0 mg/kg b.w./day for 6 months. The prolongated WD intake induced obesity and glucose intolerance, increasing body weight and fat. WD induced morphological changes and increased PCNA-positive epithelial cells in prostate. Additionally, the WD increased gene expression of AR, antioxidant targets, inflammation-related cytokines, cell repair and turnover, and targets related to methylation and miRNAs biosynthesis compared to the counterpart (basal diet). 2,4-D (0.02 and 2.0) changed prostate morphology and gene expression evoked by WD. In contrast, the WD group exposed to 20 mg/kg of 2,4-D reduced feed intake and body weight, and increased expression of androgen receptor and genes related to cell repair and DNA methylation compared to the negative control. Our results showed that 2,4-D was able to modulate the effects caused by WD, mainly at lower doses. However, further studies are needed to elucidate the mechanisms of 2,4-D on the obesogenic environment caused by the WD.

Abstract
Spaceflight is known to diminish bone mass and reduce immune function, suggesting that repair of connective tissue might be impaired in a microgravity environment. Fisher 344 rats were used to test wound healing responses in the orbiting Space Shuttle Endeavour by preflight implantation of polyvinyl acetal sponge disks in which pellets were placed to release either platelet-derived growth factor (PDGF-BB), basic fibroblast growth factor (bFGF), or placebo. Control groups on the ground included a matched environment group in similar housing modules and temperature control groups in cages at 22 degreesC and 28 degreesC. After 12 days of implantation and 10 days in orbit, the removed sponges were analyzed for histological and biochemical responses. Growth factor responses were histologically evident after release of PDGF-BB and bFGF in ground controls, whereas only immediate-release bFGF and delayed-release PDGF-BB showed significant responses in microgravity. Biochemical data confirmed that cellularity was increased by both factors in ground sponges; however, this response was significantly blunted in flight sponges (P<0.005, ANOVA), irrespective timing of factor release. Collagen content was 62% lower in sponges from animals with 10 days of microgravity exposure (P<0.01, ANOVA) and further reduced by bFGF. These data suggest that orbital exposure retards the capacity of wounds to heal and respond to exogenous stimuli.

Abstract
Hyaluronic acid and its derivatives show promise as biomaterials in wound healing applications. Studies of cutaneous wound repair were carried out in two animal models to compare the biological effects of hyaluronic acid and hyaluronic acid ethyl ester, a new semisynthetic derivative. The two compounds were tested in partial-thickness excisional wounds in 40-kg pigs and full-thickness excisional wounds in the rabbit ear as 0.2% (w/w) formulations in a neutral Na alginate vehicle. All compounds were administered daily under an occlusive, polyurethane dressing. Neither hyaluronic acid nor the hyaluronic acid ethyl ester showed toxic or inflammatory influences over the observation period of about 2 weeks. Morphometric analysis of porcine wounds revealed small differences among treatment groups which may have been masked by the effect of the vehicle. The rabbit ear model data suggested a very slight inhibition of wound closure. Biochemical analysis of ear wounds showed this injury model to be a sensitive system for evaluation of vulnerary agents. The hyaluronate-treated wounds tended to accumulate collagen more slowly, which may reflect the capacity of these compounds to modify the scarring process. Given the ability to fabricate hyaluronate esters into films and fibers, these data suggest that such biomaterials will not, by themselves, exert a negative influence on the repair process and may improve healing, either alone or in combination with other soluble agents.

Abstract
Exogenous polypeptide growth factors influence the rate of wound healing and other biological processes, but there is no direct evidence that these peptides have an intrinsic role. To test whether basic fibroblast growth factor is involved in wound repair, rats were implanted with subcutaneous polyvinyl alcohol sponges containing slow-release pellets releasing either a polyclonal neutralizing antiserum directed against basic fibroblast growth factor, preimmune IgG, or nothing. Histological and biochemical evaluation of the granulation tissue that infiltrated the sponges showed anti-basic fibroblast growth factor to cause significant reductions in DNA, protein, and collagen content when compared with either preimmune IgG or placebo at the early stages of wound repair.

Abstract
Basic fibroblast growth factor (bFGF) stimulates extracellular matrix metabolism, growth, and movement of mesodermally derived cells. We have previously shown that collagen content in polyvinyl alcohol sponges increased after bFGF treatment. We hypothesized that bFGF-treated incisional wounds would heal more rapidly. After intraperitoneal pentobarbital anesthesia, male, 200- to 250-g, Sprague-Dawley rats (n = 27) each underwent two sets of paired, transverse, dorsal incisions closed with steel sutures. On Day 3 postwounding, 0.4 ml of bFGF (recombinant, 400 ng. Synergen) or normal saline was injected into one of each paired incisions. Animals were killed with ether on postwounding Days 5, 6, and 7 and their dorsal pelts were excised. Fresh or formalin-fixed wound strips were subjected to tensile strength measurements using a tensiometer. Breaking energy was calculated. Wound collagen content (hydroxyproline) was measured in wound-edge samples following hydrolysis using high-performance liquid chromatography. There was an overall significant increase in fresh wound tensile strength (13.7 +/- 1.06 vs 19.1 +/- 1.99 g/mm, P less than 0.01) and wound breaking energy (476 +/- 47 vs 747 +/- 76 mm2, P less than 0.001) in bFGF-treated incisions. There was an increase in wound collagen content which was not statistically significant and there was no difference in fixed incisional tensile strength. Histologic examination showed better organization and maturation in bFGF wounds. Recombinant bFGF accelerates normal rat wound healing. This may be due to earlier accumulation of collagen and fibroblasts and/or to greater collagen crosslinking in bFGF-treated wounds.

Abstract
In male Wistar rats the behaviour of the plasma concentrations of thyroid hormones, corticosterone, adrenocorticotrophic hormone and insulin was examined in the course of a hypokinase stress of 6 weeks duration. Blood was taken after a stress of 1, 3 and 6 weeks. In these cases in thyroid hormones a decrease of the thyroxine (T4) and an increase of the triiodothyronine (T3) appeared. In an increased need of energy of the organism apparently a more rapid peripheral conversion of T4 to the more active metabolic T3 takes place. Only after a longer stress the deficit of thyroid hormone is equalized via the regulating circle hypothalamus-hypophysis-thyroid gland. The hormones ACTH and corticosterone which are connected together in the regulation system hypothalamus-hypophysis-adrenal cortex, after one week slightly increase in the plasma of rats and clearly decrease after a stress of 3 weeks. This shows that in a longer stress load apparently an exhaustion of the bioenergetic reserves of the organism develops. At last under long-term stress a significant decrease of the plasma insulin level was found. The decrease of insulin might be conditioned by an endogenic liberation of catecholamine.
