Abstract
Monepantel (MPL) is a new anthelmintic agent approved for the treatment of nematode infections in farm animals. As a nematicide, it acts through a nematode-specific nicotinic receptor subtype which explains its exceptional safety in rodents and mammals. In the present study, we evaluated its potential as an anticancer agent. In vitro treatment of epithelial ovarian cancer cells with MPL resulted in reduced cell viability, inhibition of cell proliferation and suppression of colony formation. Proliferation of human ovarian surface epithelial cells and other non-malignant cells were however minimally affected. MPL-induced inhibition was found to be independent of the acetylcholine nicotinic receptor (nAChR) indicating that, its target in cancer cells is probably different from that in nematodes. Analysis of MPL treated cells by flow cytometry revealed G1 phase cell cycle arrest. Accordingly, MPL treated cells expressed reduced levels of cyclins D1 and A whereas cyclin E2 expression was enhanced. Consistent with a G1 phase arrest, cellular levels of cyclin dependent kinases (CDKs) 2 and 4 were lower, whereas expression of CDK inhibitor p27(kip) was increased. In cells expressing the wild-type p53, MPL treatment led to increased p53 expression. In line with these results, MPL suppressed cellular thymidine incorporation thus impairing DNA synthesis and inducing cleavage of poly (ADP-ribose) polymerase (PARP-1). Combined these pre-clinical findings reveal for the first time the anticancer potential of monepantel.

Abstract
Cell migration is a dynamic process that is central to a variety of physiological functions as well as disease pathogenesis. The modulation of cell migration by p27 (officially known as CDKN1B) has been reported, but the exact mechanism(s) whereby p27 interacts with downstream effectors that control cell migration have not been elucidated. By systematically comparing p27(+/+) mouse embryonic fibroblasts (MEFs) with genetically ablated p27(-/-) MEFs using wound-healing, transwell and time-lapse microscopic analyses, we provide direct evidence that p27 inhibits both directional and random cell migration. Identical results were obtained with normal and cancer epithelial cells using complementary knockdown and overexpression approaches. Additional studies revealed that overexpression of manganese superoxide dismutase (MnSOD, officially known as SOD2) and reduced intracellular oxidation played a key role in increased cell migration in p27-deficient cells. Furthermore, we identified signal transducer and activator of transcription 3 (STAT3) as the transcription factor responsible for p27-regulated MnSOD expression, which was further mediated by ERK- and ATF1-dependent transactivation of the cAMP response element (CRE) within the Stat3 promoter. Collectively, our data strongly indicate that p27 plays a crucial negative role in cell migration by inhibiting MnSOD expression in a STAT3-dependent manner.

Abstract
BACKGROUND/AIM Deregulation of the normal cell cycle is common in upper urothelial carcinoma (UUC). The aim of this study was to investigate the expression of regulatory proteins of the cell cycle (p53, p16, cyclin D1, HER-2) and proliferative Ki-67 activity in UUC, and to determine their interaction and influence on the phenotypic characteristics of UUC. METHODS In 44 patients with UUC, histopathological and immunohistochemical analyses (p53, p16, cyclin D1, HER-2, and Ki-67) of tumors were done. RESULTS Overexpression/altered expression of p53, p16, cyclin D1 or HER-2 was detected in 20%, 57%, 64%, and 57% of tumors, respectively. Eleven (25%) UUC had a high proliferative Ki-67 index. Forty patients (91%) had at least one marker altered, while four (9%) tumors had a wild-type status. Analysis of relationship between expressions of molecular markers showed that only high expression of p53 was significantly associated with altered p16 activity (p < 0.05). High Ki-67 index was associated with the high stage (p < 0.005), solid growth (p < 0.01), high grade (p < 0.05), and multifocality p < 0.05) of UUC, while high expression of p53 was associated with the solid growth (p < 0.05). In regression models that included all molecular markers and phenotypic characteristics, only Ki-67 correlated with the growth (p < 0.0001), stage (p < 0.01), grade (p < 0.05) and multifocality (p < 0.05) of UCC; (Ki-67 and HER-2 expression correlated with the lymphovascular invasion (p < 0.05). CONCLUSIONS This investigation showed that only negative regulatory proteins of the cell cycle, p53 and p16, were significantly associated in UUC, while proliferative marker Ki-67 was in relation to the key phenotypic characteristics of UUC in the best way.

Abstract
Aim: To examine p27 (Kip 1) and MUC1 expression in specimens of papillary transitional cell carcinoma (PTCC) of the urinary bladder and to correlate their expression with the tumor grades,stages and outcome. Patients and Methods: Paraffin sections from previously diagnosed PTCC bladder were graded, staged and the patients were followed up for 5 years. Ten non-neoplastic urological lesions diagnosed as polypoid cystitis were taken as control. Three sections of 4 um thickness were obtained from every case. One was hematoxylin and eosin (H and E) stained for diagnosis, reviewing and confirmation. The other two sections were immunohistochemically stained for both p27and MUC1. The data of immunohistochemical results were correlated with the following conventional prognostic variables: tumor grade, stage, distant metastasis and 5 year survival. Results: The results showed a highly significant and an insignificant relationship between p27 expression and tumor grade and stage (P<0.01 and P>0.05), respectively. Correlating p27 expression with distant metastasis and overall survival showed a significant relationship with distant metastasis (P<0.05) and a highly significant one with overall survival (P<0.01). The results showed also a significant relationship between MUC1 expression and both tumor grade (P<0.01) and overall survival (P<0.05). Conclusion: p27 and MUC1 immunohistochemistry augment the classic histochemistry for the prognosis of PTCC of the bladder as well as improving the prediction of the patient outcome and survival.

Abstract
AIM To investigate cell cycle proteins in chronic hepatitis C virus infection in order to analyze their role in the process of hepatocyte transformation and to characterize their prognostic properties. METHODS Subjects of the current study included 50 cases of chronic hepatitis C (CHC) without cirrhosis, 30 cases of CHC with liver cirrhosis (LC), and 30 cases of hepatitis C-related hepatocellular carcinoma (HCC) admitted to the Department of Hepato-Gastroenterology, Theodor Bilharz Research Institute (TBRI), Giza, Egypt. Fifteen wedge liver biopsies, taken during laparoscopic cholecystectomy, were also included as normal controls. Laboratory investigations including urine and stool analysis, liver function tests and prothrombin concentration; serologic markers for viral hepatitis and ultrasonography were done for all cases of the study together with immunohistochemical analysis using primary antibodies against Cyclin D1, Cyclin E, p21, p27 and Rb/p105 proteins. RESULTS Normal wedge liver biopsies didn't express Cyclin E or Rb/p105 immunostaining but show positive staining for Cyclin D1, p21 and p27. Cyclin D1 expressed nuclear staining that was sequentially increased from CHC to LC (P < 0.01) to HCC (P < 0.001) cases; meanwhile, Cyclin E revealed nuclear positivity only in the case of HCCs patients that was directly correlated to Rb/p105 immuno-reactivity. The expression of p21 and p27 was significantly increased in CHC and LC cases compared to normal controls and HCCs with no significant difference between well- and poorly-differentiated tumors. p21 showed only a nuclear pattern of staining, while, p27 presented with either cytoplasmic and/or nuclear reactivity in all studied cases. Correlation analysis revealed a direct relation between Cyclin D1 and p21 in CHC cases (P < 0.001), between Cyclin D1 and Cyclin E in HCCs (P < 0.01); however, an inverse relationship was detected between Cyclin D1 and p21 or p27 (P < 0.001) and between p21 and Rb/p105 (P < 0.05) in HCCs. CONCLUSION Upregulation of Cyclin D1 in CHC plays a vital role in the development and differentiation of HCC; while, Cyclin E may be a useful marker formonitoring tumor behavior. p21 and p27 can be used as predictive markers for HCC. Furthermore, higher expression of Rb/p105 as well as inverse relation with p21 and histologic grades suggests its important role in hepatic carcinogenesis.

Abstract
BACKGROUND For the female population in Asia, systematic investigation on alterations of cyclin D1 in breast carcinoma is rare, and correlation between cyclin D1 expression with clinicopathological parameters, survival rate, and other prognostic marker associated with cell cycle is unclear. METHODS Expression of cyclin D1 protein, Ki-67, pRb, and p53 was determined by immunohistochemistry in 18 cases of early breast carcinomas and 80 cases of invasive ductal carcinomas. Genetic alteration of cyclin D1 gene and overexpression of cyclin D1 mRNA were detected by Southern blot and RT-PCR, respectively. RESULTS Expression of cyclin D1 is negative in usual ductal hyperplasia (UDH) and atypical ductal hyperplasia (ADH). However, in 52.0% (51/98) of all breast carcinomas, positive expression of cyclin D1 was observed. Five-year survival rate of the patients with positive expression of cyclin D1 (52.7%) is significantly lower than the cases with negative expression of cyclin D1 (72.1%). Positive rate of cyclin D1 protein in invasive ductal carcinoma (52.5%) is slightly higher than overexpression rate (40.8%) of cyclin D1 mRNA but significantly higher than amplification rate of cyclin D1 gene (18.4%). Expression of cyclin D1 is correlated with Ki-67 expression, but not correlated with pRb and p53 expression. CONCLUSIONS Positive expression of cyclin D1 could serve as a poor prognostic marker for Chinese patients with breast carcinoma independent of nodal metastasis and clinical stage. Expression of cyclin D1 protein is affected more directly by overexpression of cyclin D1 mRNA rather than cyclin D1 gene amplification. The cooperation between pRb and p53 with cyclin D1 protein in the carcinogenesis of breast carcinoma is not supported by the results.

Abstract
The marine organisms produce many metabolic substances with numerous pharmacological activities. It has been suggested that ilimaquinone, a metabolite of sea sponge, can induce vesiculation of the Golgi apparatus and display several biological activities, such as anti-human immunodeficiency virus, anti-inflammation as well as anti-microbial activities. In this study, the sulforhodamine B assays showed that ilimaquinone induced a concentration-dependent anti-proliferative effect in several types of cancer cell lines, including prostate cancer PC-3 and LNCaP, non-small cell lung cancer A549 and hepatocellular carcinoma Hep3B cells. The anticancer mechanism of ilimaquinone in the representative PC-3 cells was identified. Ilimaquinone induced a time-dependent increase of G(1) phase arrest and a subsequent increase of hypodiploid sub-G(1) phase (apoptosis) of the cell cycle. The arrest of the cell cycle was associated with a sustained high level of nuclear cyclin E but the absence of DNA synthesis by flow cytometric analysis, indicating an incomplete S phase. Although ilimaquinone-induced Golgi vesiculation, the data showed that the inhibition of cancer cell growth was not through the Golgi fragmentation. Several biological kinases and transcription factors were examined in this study. The data demonstrated that ilimaquinone did not activate extracellular signal-regulated kinase and phosphatidylinositol 3-kinase but induce the up-regulation and nuclear translocation of growth arrest and DNA damage inducible gene 153 (CHOP/GADD153). Furthermore, ilimaquinone-mediated anti-proliferative effect is significantly reduced in the antisense CHOP/GADD153-overexpressing cells. Ilimaquinone also inhibited DNA binding of NF-kappaB; however, this inhibitory effect could not explain ilimaquinone-induced anticancer effect. In summary, it is suggested that ilimaquinone induces the anti-proliferative effect through the G(1) arrest of the cell cycle and the up-regulation and nuclear translocation of CHOP/GADD153.

Abstract
INTRODUCTION AND OBJECTIVES To retrospectively assess the relationship between immunohistochemical expression of p53, p21, p16, and cyclin D1, with recurrence, progression and survival in superficial bladder cancer. METHODS 163 patients undergoing transurethral resection for superficial bladder cancer between February 1995 and March 2004. Tumor samples were included in a tissue microarray support that was serially sectioned for immunohistochemical staining. Grade and stage associations for each marker were evaluated by the Chi-square test. Assessment of the relationship with recurrence, progression, and survival Kaplan-Meier curves and log-rank test were used. RESULTS There were no statistically significant differences in marker expression depending on tumor grade and stage, with the exception of Cyclin D1, that was significantly different depending on tumor stage (p=0.030). p21 expression was related to tumor recurrence (p=0.035), progression (p=0.008) and survival (p=0.034). p16 expression was also related to recurrence (p=0.048) and survival (p=0.047), but not to tumor progression (p=0.116). p53 and Cyclin D1 were not statistically associated with tumor recurrence, progression or survival. CONCLUSIONS In our experience, only p16 and p21 may be useful in the management of superficial bladder tumors, as they are predictors of recurrence and survival in Ta and T1 patients.
