Abstract
INTRODUCTION The intake of angiotensin-converting enzyme (ACE) inhibitors and specific antagonists of angiotensin II receptors, widely used as antihypertensive drugs, significantly reduces the risk of developing basal cell carcinoma (BCC), highlighting the possible tumorigenic role of angiotensin II (AngII). We present here the investigated genetic association between the development of BCC and functional DNA polymorphisms M235T, I/D, and A1903G in the genes of angiotensinogen (AGT), angiotensin-converting enzyme (ACE), and chymase (CMA1), which mediate AngII production levels. METHODS DNA samples of 203 unrelated Greeks were studied, including 100 patients with BCC and 103 matched healthy controls. RESULTS The MT genotype of the AGT-M235T polymorphism was significantly more prevalent in the patient group (78.0%) versus the healthy control group (28.3%; p < 0.001). The DD genotype of the ACE-I/D polymorphism was also increased in BCC patients (72.8%) compared to controls (46.2%; p = 0.001). The heterozygous AG genotype of CMA1-A1903G was significantly more frequent in the BCC group (86%) than in the healthy controls (50.5%; p < 0.001). CONCLUSIONS The MT, DD, and AG genotypes of the AGT- M235T, ACE-I/D, and CMA1-A1903G polymorphisms, respectively, were significantly increased in frequency within the group of cancer patients compared to the healthy controls. All three genotypes correspond to increased enzyme levels or activity and result in increased levels of AngII; therefore, they may be potentially utilized as reliable biomarkers associated with an individual's increased risk for BCC development.

Abstract
The objective of this meta-analysis was to estimate the association of ACE I/D, -240 A > T and AT1R 1166 A > C polymorphisms with breast cancer (BC) risk. A comprehensive search on databases was conducted to identify all eligible case-control studies. Finally, 35 case-control studies, including 20 studies for ACE I/D, seven studies for ACE 240 A > T, and eight studies for AT1R 1166 A > C were included. The pooled analysis showed a significant association between ACE I/D polymorphism and BC risk under three genetic models, i.e., heterozygote (ID vs. DD: OR = 0.707, 95% CI 0.528-0.946, p = 0.020), homozygote (II vs. DD: OR = 0.662, 95% CI 0.462-0.947, p = 0.024), and dominant (II + ID vs. DD: OR = 0.691, 95% CI 0.507-0.941, p = 0.019). A significant association was also observed in ACE I/D polymorphism with BC risk among Asians and Caucasians. However, ACE -240 A > T and AT1R 1166 A > C polymorphisms were not associated with BC. Stratified analyses by ethnicity showed a significant association of ACE -240 A > T and AT1R 1166 A > C polymorphisms with BC risk in Latinos populations, but not in Asians. This meta-analysis inconsistence with all previous meta-analyses suggests that the ACE I/D might be associated with BC in overall and by ethnicity. However, the ACE -240 A > T and AT1R 1166 A > C were associated with BC risk only among Latinos populations.

Abstract
Day by day, the health and economical burden of cancer increases globally. Indeed it can be considered that there is ''cancer pandemic''. Blocking the renin-angiotensin system (RAS) by angiotensin-converting enzyme (ACE) inhibitors (ACEI) or angiotensin-receptor blockers (ARB) are widely used measures to treat hypertension and heart failure. It has been recently suggested the activation and blocking of RAS has been associated with various types of cancer in epidemiological and experimental studies. Various studies have shown that RAS blockage is protective in some cancers. However, although fewer, contradictory data also showed that RAS blockage is either not related or adversely related to cancer. Although the reasons for these findings are not exactly known, different types of receptors and effectors in RAS may account for these findings. In the current review, we summarize the different RAS receptors and cancer development with regard to epidemiology, and pathogenesis including cell signaling pathways, apoptosis, genetic and epigenetic factors.

Abstract
A number of investigations have addressed the importance of high glucose in breast cancer, however, the involvement of angiotensinogen (AGT) in this scenario is yet to be defined. Here we set out to analyze the potential pro-tumor effects of high glucose in breast cancer, and understand the underlying molecular mechanism. We demonstrated that high glucose promoted cell proliferation, viability, and anchorage-independent growth of breast cancer cells. In addition, the migrative and invasive capacities were significantly enhanced by high glucose medium. Mechanistically, AGT expression was inhibited by high glucose at both transcriptional and translational levels. High AGT remarkably suppressed proliferation, inhibited viability, and compromised migration/invasion of breast cancer cells. Most importantly, ectopic introduction of AGT almost completely abrogated pro-tumor effects of high glucose. Our study has characterized the pro-tumor properties of high glucose in breast cancer cells, which is predominantly attributed to the suppression of AGT.

Abstract
Objective: The association between angiotensin II type 1 receptor
(AGTR1) gene A1166C polymorphism and
cancer risk has been investigated in many studies. However, the results have
been inconclusive. A meta-analysis was performed to obtain a more precise
estimation of the relationship. Methods: The PubMed and China National Knowledge Infrastructure databases were
searched for published literature. Odds ratios (ORs) with 95% confidence
intervals (CIs) were used to assess the strengths of association. Results: Ten studies, including 1553 patients and 1904 controls, were included in the
meta-analysis. Overall, there were no significant associations between the
AGTR1 gene A1166C polymorphism and
cancer risk in the general population (CC vs AA: OR = 1.09, 95% CI =
0.50–2.37; AC vs AA: OR = 1.54, 95% CI = 0.81–2.91; dominant model: OR =
1.46, 95% CI = 0.77–2.79; recessive model: OR = 1.12, 95% CI = 0.84–1.49).
In a subgroup analysis by nationality and cancer type, the results also
showed no association between this polymorphism and cancer risk. Conclusions: This meta-analysis demonstrated that the AGTR1 gene
A1166C polymorphism does not appear to be related to
the risk of cancer.

Abstract
Background: A number of case-control studies were conducted to investigate the association of angiotensin converting enzyme insertion/deletion (ACE I/D) polymorphism with breast cancer. But the results remain controversial. This meta-analysis aims to comprehensively evaluate the association of ACE I/D polymorphism with breast cancer. Method: A comprehensive literature search on PubMed, Google Scholar, SCOPUS and ISI Web of Knowledge databases for studies published up to June 01, 2018 was performed. Summary odds ratios (ORs) and 95% confidence intervals (CI) were estimated. Publication bias of literatures was evaluated using funnel plots and Egger’s test. Results: A total of 20 studies including 2846 breast cancer cases 9,299 controls meeting the predefined criteria were involved in the meta-analysis. Overall, the ACE I/D polymorphisms was significantly associated with breast cancer under the allele model (I vs. D: OR= 0.803, 95% CI 0.647-0.996, p=0.046), the homozygote model (II vs. DD: OR= 0.662, 95% CI 0.462-0.947, p=0.024), the heterozygote model (ID vs. DD: OR= 0.707, 95% CI 0.528-0.946, p=0.020), the dominant model (II+ID vs. DD: OR= 0.691, 95% CI 0.507-0.941, p=0.019). In the subgroup analysis by ethnicity, a significant association was found among Asian and Caucasian populations, but not among mixed populations. Conclusions: This meta-analysis suggests that ACE I/D polymorphism may be associated with increased risk of breast cancer, especially among Asian and Caucasians. However, well-designed studies with larger sample size and more ethnic groups are needed to further validate the results.

Abstract
Studies of the association between angiotensin II receptor type 1 A1166C (AGTR1 A1166C) polymorphism and chronic kidney disease (CKD) risk have yielded conflicting results. We conducted a combined case-control study and meta-analysis to better define this association. The case-control study included 634 end-stage renal disease (ESRD) patients and 739 healthy controls. AGTR1 A1166C genotype was determined using polymerase chain reaction and iPLEX Gold SNP genotyping methods. The meta-analysis included 24 studies found in the PubMed and Cochrane Library databases. Together, the case-control study and meta-analysis included 36 populations (7,918 cases and 6,905 controls). We found no association between the C allele and ESRD (case-control study: OR: 1.02, 95% CI: 0.77–1.37; meta-analysis: OR: 1.07; 95% CI: 0.97–1.18). Co-dominant, dominant, and recessive model results were also not significant. No known environmental factors moderated the effect of AGTR1 A1166C on CKD in our gene-environment interaction analysis. Sensitivity analysis showed an AGTR1 A1166C-CKD association in Indian populations (OR: 1.46, 95% CI: 1.26–1.69), but not in East Asian or Caucasian populations. Additional South Asian studies will be required to confirm the potential role of this polymorphism in CKD.

Abstract
The most common complication of pregnancy is idiopathic recurrent pregnancy loss (RPL). To identify the contribution of gene polymorphisms to this condition, we evaluated the association between RPL and the angiotensinogen (AGT), angiotensin receptor 1 (AGTR1) and Angiotensinogen converting enzyme (ACE). In this case-control study, the frequency of AGT (rs4762 and rs699), AGTR1 (rs5186) and ACE insertion/deletion (rs4340) polymorphisms in 202 idiopathic RPL women was compared with 210 women with no history of abortion, using tetra-primer ARMS-PCR. Polymorphisms were analysed by logistic regression analysis according to inheritance models. The CT genotype of AGT rs4762, the CC genotype of AGT rs699 and the AC genotype of AGTR1 rs5186 in a co-dominant inheritance model were associated with idiopathic RPL (OR = 1.63, 95% CI = 1.07-2.49 of CT versus CC; OR = 5.97, 95% CI = 1.28-27.82 of CC versus TT; and OR = 1.99, 95% CI = 1.22-3.07 of AC versus AA). The allele frequency of AGT rs699 and AGTR1 rs5186 polymorphisms, but not AGT rs4762 and ACE rs4340 polymorphisms were significantly different between women with RPL patients and controls (p = 0.020, p = 0.003, p = 0.105 and p = 0.065, respectively). These results show that there is a significant relationship between AGT (rs699) and AGTR1 (rs5186) polymorphisms and idiopathic RPL in the Iranian population.

Abstract
A detailed understanding of the relationship between radiation-induced breast cancer and obesity is needed for appropriate risk management and to prevent the development of a secondary cancer in patients who have been treated with radiation. Our goal was to develop an animal model to study the relationship by combining two existing Sprague-Dawley rat models of radiation-induced mammary carcinogenesis and diet-induced obesity. Female rats were fed a high-fat diet for 4 weeks and categorized as obesity prone or obesity resistant based on their body weight at 7 weeks of age, at which time the rats were irradiated with 4 Gy. Control rats were fed a standard diet and irradiated at the same time and in the same manner. All rats were maintained on their initial diets and assessed for palpable mammary cancers once a week for the next 30 weeks. The obesity-prone rats were heavier than those in the other groups. The obesity-prone rats were also younger than the other animals at the first detection of mammary carcinomas and their carcinoma weights were greater. A tendency toward higher insulin and leptin blood levels were observed in the obesity-prone rats compared to the other two groups. Blood angiotensin II levels were elevated in the obesity-prone and obesity-resistant rats. Genes related to translation and oxidative phosphorylation were upregulated in the carcinomas of obesity-prone rats. Expression profiles from human breast cancers were used to validate this animal model. As angiotensin is potentially an important factor in obesity-related morbidities and breast cancer, a second set of rats was fed in a similar manner, irradiated and then treated with an angiotensin-receptor blocker, losartan and candesartan. Neither blocker altered mammary carcinogenesis; analyses of losartan-treated animals indicated that expression of renin in the renal cortex and of Agtr1a (angiotensin II receptor, type 1) in cancer tissue was significantly upregulated, suggesting the presence of compensating mechanisms for blocking angiotensin-receptor signaling. Thus, obesity-related elevation of insulin and leptin blood levels and an increase in available energy may facilitate sustained protein synthesis in cancer cells, which is required for rapid cancer development.

Abstract
BACKGROUND Currently, there are no predictive biomarkers for anti-angiogenic strategies in cancer, but response to anti-angiogenic drugs is associated with development of hypertension secondary to treatment. Therefore, this study explored the clinical relevance of genetic polymorphisms in some components of the renin-angiotensin system (RAS). MATERIAL AND METHODS Genomic DNA was isolated from peripheral blood from 95 metastatic breast or colorectal cancer patients treated with bevacizumab, and AGTR1-A1166C (rs5186), AGT-M235T (rs699) SNPs and ACE I/D (rs4646994) polymorphisms were genotyped using RT-PCR. Circulating vascular endothelial grow factor and angiotensin converting enzyme (ACE) levels were analysed using ELISA kits. The antitumoral activity of bevacizumab was assayed in mice orthotopically xenografted with AGTR1-overexpressing breast cancer cells. RESULTS The ACE IN/IN genotype was associated with a higher rate of disease progression compared to DEL/IN and DEL/DEL genotypes (36% vs. 11·1% P < 0·05). Similarly, AGTR1-1166A/A genotype was also associated with a higher rate of disease progression compared to AGTR1-1166A/C and AGTR1-1166C/C genotypes (24·4% vs. 2·7% P < 0·01). ACE IN/IN genotype was also found to be associated with shorter time to treatment failure compared to ACE IN/DEL and ACE DEL/DEL genotypes (14 weeks vs. 41·71, P = 0·033), whereas circulating ACE levels were found to be associated with a better response to bevacizumab treatment. Besides, in vivo experiments showed a significantly higher antitumoral activity of bevacizumab in tumours derived from AGTR1-overexpressing breast cancer cells. CONCLUSIONS A higher activity of ACE-angiotensin-II-AGTR1 axis is associated with a better response to bevacizumab, supporting that the RAS can be an important source of potential predictive markers of response to anti-angiogenic drugs.

Abstract
The prevalence of head and neck squamous cell carcinoma, HNSCC, continues to grow. Change in the expression of TP53 in HNSCC affects its downstream miRNAs and their gene targets, anomalously altering the expressions of the five genes, MEIS1, AGTR1, DTL, TYMS and BAK1. These expression alterations follow the repression of TP53 that upregulates miRNA-107, miRNA- 215, miRNA-34 b/c and miRNA-125b, but downregulates miRNA-155. The above five so far unreported genes are the targets of these miRNAs. Meta-analyses of microarray and RNA-Seq data followed by qRT-PCR validation unravel these new ones in HNSCC. The regulatory roles of TP53 on miRNA-155 and miRNA-125b differentiate the expressions of AGTR1 and BAK1in HNSCC vis-à-vis other carcinogenesis. Expression changes alter cell cycle regulation, angiogenic and blood cell formation, and apoptotic modes in affliction. Pathway analyses establish the resulting systems-level functional and mechanistic insights into the etiology of HNSCC.

Abstract
Hypertension is an established risk factor for renal cell cancer (RCC). The renin-angiotensin-aldosterone system (RAAS) regulates blood pressure and is closely linked to hypertension. RAAS additionally influences homeostasis of electrolytes (e.g. sodium and potassium) and fluid. We investigated single nucleotide polymorphisms (SNPs) in RAAS and their interactions with hypertension and intakes of sodium, potassium and fluid regarding RCC risk in the Netherlands Cohort Study (NLCS), which was initiated in 1986 and included 120,852 participants aged 55 to 69 years. Diet and lifestyle were assessed by questionnaires and toenail clippings were collected. Genotyping of toenail DNA was performed using the SEQUENOM® MassARRAY® platform for a literature-based selection of 13 candidate SNPs in seven key RAAS genes. After 20.3 years of follow-up, Cox regression analyses were conducted using a case-cohort approach including 3,583 subcohort members and 503 RCC cases. Two SNPs in AGTR1 were associated with RCC risk. AGTR1_rs1492078 (AA vs. GG) decreased RCC risk [hazard ratio (HR) (95% confidence interval (CI)): 0.70(0.49-1.00)], whereas AGTR1_rs5186 (CC vs. AA) increased RCC risk [HR(95%CI): 1.49(1.08-2.05)]. Associations were stronger in participants with hypertension. The RCC risk for AGT_rs3889728 (AG + AA vs. GG) was modified by hypertension (p interaction = 0.039). SNP-diet interactions were not significant, although HRs suggested interaction between SNPs in ACE and sodium intake. SNPs in AGTR1 and AGT influenced RCC susceptibility, and their effects were modified by hypertension. Sodium intake was differentially associated with RCC risk across genotypes of several SNPs, yet some analyses had probably inadequate power to show significant interaction. Results suggest that RAAS may be a candidate pathway in RCC etiology.

Ethnic background and genetic variation in the evaluation of cancer risk: a systematic review. PLoS One 2014; 9:e97522.

Abstract
The clinical use of genetic variation in the evaluation of cancer risk is expanding, and thus understanding how determinants of cancer susceptibility identified in one population can be applied to another is of growing importance. However there is considerable debate on the relevance of ethnic background in clinical genetics, reflecting both the significance and complexity of genetic heritage. We address this via a systematic review of reported associations with cancer risk for 82 markers in 68 studies across six different cancer types, comparing association results between ethnic groups and examining linkage disequilibrium between risk alleles and nearby genetic loci. We find that the relevance of ethnic background depends on the question. If asked whether the association of variants with disease risk is conserved across ethnic boundaries, we find that the answer is yes, the majority of markers show insignificant variability in association with cancer risk across ethnic groups. However if the question is whether a significant association between a variant and cancer risk is likely to reproduce, the answer is no, most markers do not validate in an ethnic group other than the discovery cohort's ancestry. This lack of reproducibility is not attributable to studies being inadequately populated due to low allele frequency in other ethnic groups. Instead, differences in local genomic structure between ethnic groups are associated with the strength of association with cancer risk and therefore confound interpretation of the implied physiologic association tracked by the disease allele. This suggest that a biological association for cancer risk alleles may be broadly consistent across ethnic boundaries, but reproduction of a clinical study in another ethnic group is uncommon, in part due to confounding genomic architecture. As clinical studies are increasingly performed globally this has important implications for how cancer risk stratifiers should be studied and employed.

Abstract
The Alu repetitive sequence insertion/deletion (I/D, rs4646994) polymorphism in the angiotensin I-converting enzyme (ACE) gene may alter cancer susceptibility, but results of current studies are inconclusive. To derive a more precise estimation of the relationship between the ACE I/D polymorphism and cancer risk, we performed an updated meta-analysis of all eligible studies. All studies published up to July 2013 concerning the association between the ACE I/D polymorphism and cancer risk were identified by systematically searching PubMed, EMBASE, Wanfang, CNKI, and Cqvip databases. The odds ratios (ORs) with 95 % confidence intervals (CIs) were pooled using the fixed/random-effects model in Review Manager 5.1 and STATA 12.0. A total of 46 case-control studies including 7,025 cases and 34,911 controls were identified and evaluated. Overall, we did not observe a direct association between the ACE I/D polymorphism and general cancer risk (DD + DI vs. II OR = 0.95, 95 %CI = 0.84-1.07, P = 0.40). In the subgroup analysis by cancer type, a significant increased susceptibility of prostate cancer was found for variant homozygotes (DD vs. II + ID OR = 2.15, 95 %CI = 1.01-4.55, P = 0.05). Additionally, no significant association was observed in other subgroup analyses according to ethnicity, control source, sample size and quality control of genotyping. In summary, our results suggested that the ACE I/D polymorphism might not be a common risk factor for overall cancer susceptibility, but might contribute to the susceptibility of prostate cancer. More studies with larger sample sizes are required in the future.

Abstract
We aimed to evaluate the association of four common polymorphisms (rs1800625, rs1800624, rs2070600, and rs184003) in receptor for advanced glycation end products (RAGE) gene to evaluate their epistatic influence on breast cancer risk in northeastern Han Chinese. This is a hospital-based case-control study involving 509 histologically-proven breast cancer patients and 504 cancer-free controls. The genotype and allele distributions of rs184003 differed significantly between patients and controls, even after the Bonferroni correction. Individuals carrying the rs184003 T allele exhibited 1.62-fold increased risk of breast cancer (odds ratio (OR) = 1.62; 95% confidence interval (95% CI): 1.26–2.08; P < 0.001) after adjusting for confounders. The frequency of haplotype T-T-G-T (alleles in order of rs1800625, rs1800624, rs2070600, and rs184003) was remarkably higher in patients than in controls (Simulated P = 0.001), and this haplotype was significantly associated with a 1.43-fold (95% CI: 1.01–2.01; P = 0.041) increase in adjusted risk of breast cancer. Further analysis indicated that there was synergistic interaction between rs184003 and rs2070600, whereas their joint information gain value was relatively small (0.27%). Taken together, although there was no suggestive evidence for the presence of epistasis in RAGE gene, our findings clearly demonstrate that rs184003 might play a predominant role in the development of breast cancer.

Abstract
BACKGROUND Epidemiological studies have evaluated the association between 3801T>C polymorphism of CYP1A1 gene and the risk for idiopathic male infertility, but the results are inconclusive. We aimed to derive a more precise estimation of the relationship by conducting a meta-analysis of case-control studies. METHODS This study conformed to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. PubMed, Embase and CNKI databases were searched through November 2013 to identify relevant studies. Pooled odds ratios with 95% confidence intervals were used to assess the strength of the association between CYP1A1 3801T>C polymorphism and idiopathic male infertility risk. Q-test was performed to evaluate between-study heterogeneity and publication bias was appraised using funnel plots. Sensitivity analyses were conducted to evaluate the robustness of meta-analysis findings. RESULTS Six studies involving 1,060 cases and 1,225 controls were included in this meta-analysis. Overall, significant associations between 3801T>C polymorphism and idiopathic male infertility risk were observed in allelic comparison (OR = 1.36, 95% CI: 1.01-1.83), homozygous model (OR = 2.18, 95% CI: 1.15-4.12), and recessive model (OR = 1.86, 95% CI: 1.09-3.20), with robust findings according to sensitivity analyses. However, subgroup analyses did not further identify the susceptibility to idiopathic male infertility in all comparisons. Funnel plot inspections did not reveal evidence of publication bias. CONCLUSIONS The current meta-analysis provides evidence of a significant association between CYP1A1 3801T>C polymorphism and idiopathic male infertility risk. Considering the limitation inherited from the eligible studies, further confirmation in large-scale and well-designed studies is needed.

Abstract
Sporadic colorectal cancer (CRC) is a typical multifactorial disease. Isothiocyanates (ITC) have been recently shown to inhibit development of CRC in many experimental models. MicroRNAs (miRNAs) are short noncoding RNAs that posttranscriptionally regulate gene expression through binding to 3' untranslated regions (3'UTR) of target mRNAs. MiRNAs are regulated by natural agents, ITCs included. In our study, using global expression profiling based on TaqMan Low-Density Arrays, we identified 3 common miRNAs (miR-155, miR-23b, miR-27b) regulated by ITCs (sulforaphane, iberin) in colonic epithelial cell lines NCM460 and NCM356. In silico predictions allowed us to find 9 relevant single nucleotide polymorphisms (SNPs) localized within the 3'UTRs of genes (AGTR1, TNFAIP2, PRKCB, HSPA9, RABGAP1, DICER1, ADAM19, VWA5A, and SIRT5) targeted by these ITC-related miRNAs. Finally, we observed that homozygous CC genotype of DICER1, rs1057035, was significantly associated with decreased risk of CRC (odds ratio = 0.49; 95% confidence interval: 0.25-0.95, P = 0.036) when compared to TT homozygote genotype; also, the C allele tended to have a protective effect (P = 0.072). This study showed that miRNAs could be involved in chemoprotective effects of natural agents; their function alteration through SNPs in their binding sites and flanking regions presents a new class of CRC risk factors.

Abstract
OBJECTIVE The angiotensinogen (AGT) gene has been considered to be implicated in the development of cancer. However, the results have been inconsistent. In this study, we performed a meta-analysis to clarify the association of AGT M235T variant with cancer risk. METHODS Published literature from PubMed and Embase were retrieved. Pooled odds ratio (OR) with 95% confidence interval (CI) was calculated using a fixed- or random-effects model. RESULTS A total of seven articles including eight studies (3639 cancer cases and 6684 controls) for AGT M235T variant were included. The present meta-analysis showed that AGT M235T variant was marginally associated with cancer risk under dominant model (OR=1.12, 95% CI=1.02-1.24). However, the positive association was not stable after sensitivity analysis. Further subgroup analysis by cancer type did not suggest any association of AGT M235T variant with various cancers (all p>0.05). CONCLUSION The present meta-analysis demonstrated that AGT M235T variant was not associated with risk of all cancer or various cancers. Further well-designed studies with large sample size should be conducted to confirm or refute the non-significant association.

Abstract
Recently, several meta-analysis suggested an increased risk of cancers linked to the use of antagonists of angiotensin-2 receptors or inhibitors of angiotensinogen converting enzyme. The results of epidemiological studies are conflicting. Meta-analysis as well as retrospective studies are not reliable and biased, since they have never been designed to explore any pro- or antitumoral effect. We lack of prospective studies that could take off the doubt on these drugs. Nevertheless, all experimental researches pointed out potent antitumoral properties. Indeed, direct antiproliferative and neo-angiogenic inhibition have been described on tumor cell cultures as well as on animal models. Moreover, we are convinced that the use of antagonists of angiotensin-2 receptors and inhibitors of angiotensinogen converting enzyme may be then of clinical use in the near future in association with classical antitumor drugs. In this review, we proposed to explore these data by a thorough analysis of recent literature associating epidemiological and experimental studies.

Abstract
Association between angiotensinogen (AGT) M235T gene polymorphism and end-stage renal disease (ESRD) risk is still controversial. This meta-analysis was performed to evaluate the association of AGT M235T gene polymorphism with ESRD susceptibility. A predefined literature search and selection of eligible relevant studies were performed to collect data from electronic databases of PubMed, Embase and Cochrane Library. Sixteen literatures were identified for the analysis of association of AGT M235T gene polymorphism with ESRD risk. T allele and TT genotype were associated with ESRD susceptibility in Caucasians (T: OR = 1.13, 95 % CI: 1.02-1.25, P = 0.02; TT: OR = 1.22, 95 % CI: 1.03-1.45, P = 0.02). However, MM genotype might not play a protective role against ESRD risk in Caucasians. Furthermore, there was no a markedly positive association between AGT M235T gene polymorphism and ESRD susceptibility in overall populations, Asians and Africans. In conclusion, T allele or TT homozygote is associated with the onset of ESRD in Caucasians. However, more studies should be performed in the future.

Fang X, Netzer M, Baumgartner C, Bai C, Wang X. Genetic network and gene set enrichment analysis to identify biomarkers related to cigarette smoking and lung cancer. Cancer Treat Rev 2012; 39:77-88.

Abstract
OBJECTIVES Cigarette smoking is the most demonstrated risk factor for the development of lung cancer, while the related genetic mechanisms are still unclear. METHODS The preprocessed microarray expression dataset was downloaded from Gene Expression Omnibus database. Samples were classified according to the disease state, stage and smoking state. A new computational strategy was applied for the identification and biological interpretation of new candidate genes in lung cancer and smoking by coupling a network-based approach with gene set enrichment analysis. MEASUREMENTS Network analysis was performed by pair-wise comparison according to the disease states (tumor or normal), smoking states (current smokers or nonsmokers or former smokers), or the disease stage (stages I-IV). The most activated metabolic pathways were identified by gene set enrichment analysis. RESULTS Panels of top ranked gene candidates in smoking or cancer development were identified, including genes involved in cell proliferation and drug metabolism like cytochrome P450 and WW domain containing transcription regulator 1. Semaphorin 5A and protein phosphatase 1F are the common genes represented as major hubs in both the smoking and cancer related network. Six pathways, e.g. cell cycle, DNA replication, RNA transport, protein processing in endoplasmic reticulum, vascular smooth muscle contraction and endocytosis were commonly involved in smoking and lung cancer when comparing the top ten selected pathways. CONCLUSION New approach of bioinformatics for biomarker identification and validation can probe into deep genetic relationships between cigarette smoking and lung cancer. Our studies indicate that disease-specific network biomarkers, interaction between genes/proteins, or cross-talking of pathways provide more specific values for the development of precision therapies for lung.

Abstract
Much evidence now suggests that angiotensin II has roles in normal functions of the breast that may be altered or attenuated in cancer. Both angiotensin type 1 (AT1) and type 2 (AT2) receptors are present particularly in the secretory epithelium. Additionally, all the elements of a tissue renin-angiotensin system, angiotensinogen, prorenin and angiotensin-converting enzyme (ACE), are also present and distributed in different cell types in a manner suggesting a close relationship with sites of angiotensin II activity. These findings are consistent with the concept that stromal elements and myoepithelium are instrumental in maintaining normal epithelial structure and function. In disease, this system becomes disrupted, particularly in invasive carcinoma. Both AT1 and AT2 receptors are present in tumours and may be up-regulated in some. Experimentally, angiotensin II, acting via the AT1 receptor, increases tumour cell proliferation and angiogenesis, both these are inhibited by blocking its production or function. Epidemiological evidence on the effect of expression levels of ACE or the distribution of ACE or AT1 receptor variants in many types of cancer gives indirect support to these concepts. It is possible that there is a case for the therapeutic use of high doses of ACE inhibitors and AT1 receptor blockers in breast cancer, as there may be for AT2 receptor agonists, though this awaits full investigation. Attention is drawn to the possibility of blocking specific AT1-mediated intracellular signalling pathways, for example by AT1-directed antibodies, which exploit the possibility that the extracellular N-terminus of the AT1 receptor may have previously unsuspected signalling roles.

Angiotensin-converting enzyme insertion/deletion polymorphism and the risk of prostate cancer in the Han population of China. Med Oncol 2011; 29:1964-71. [PMID: 21874567 DOI: 10.1007/s12032-011-0051-5] [Citation(s) in RCA: 11] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2011] [Accepted: 08/16/2011] [Indexed: 10/17/2022]
Abstract
As a main effector in the renin-angiotensin system, the angiotensin II plays a critical role in cell proliferation and angiogenesis. The change between angiotensin II and its precursor is conducted by the angiotensin-converting enzyme. The association between angiotensin-converting enzyme insertion/deletion polymorphism and the activity of angiotensin-converting enzyme was testified. Furthermore, previous researches proved the association between angiotensin-converting enzyme activity and the risk of prostate cancer. Therefore, we conducted a case-control study in the Han population of China to elaborate the relation between the angiotensin-converting enzyme insertion/deletion polymorphism and prostate cancer. DNA was extracted from blood samples collected from 189 pathologically diagnosed prostate cancer patients and 290 cancer-free subjects. The angiotensin-converting enzyme insertion/deletion genotype was determined by polymerase chain reaction analysis. Stratified analyses on age (<71 or ≥ 71), cancer stage (localized or advanced), Gleason score (<7 or ≥ 7) and PSA level (<20 ng/ml or ≥ 20 ng/ml) were performed. We found the II genotype (OR = 0.304 95%CI (0.180,0.515), P < 0.001) and I allele (OR = 0.547 95%CI(0.421,0.711), P < 0.001) were associated with a decreased risk of prostate cancer compared with the DD genotype and D allele. The DD genotype was related to patients with aggressive stage of prostate cancer (OR = 2.214 95%CI(1.169, 4.194), P = 0.014) and patients diagnosed of prostate cancer at a relatively early age (OR = 0.513 95%CI(0.272, 0.965), P = 0.037). The results of our experiment supported the hypothesis that the angiotensin-converting enzyme insertion/deletion polymorphism, a potential risk factor in carcinogenesis, played an important role in the Han population of China.
