GSTP1 methylation in cancer: a liquid biopsy biomarker?

GSTP1 methylation in cancer: a liquid biopsy biomarker? Clin Chem Lab Med. 2018 Jan 06;: Authors: Gurioli G, Martignano F, Salvi S, Costantini M, Gunelli R, Casadio V Abstract The coding region of GSTP1 gene is preceded by a large CpG-rich region that is frequently affected by methylation. In many cancer types, GSTP1 is affected by hypermethylation and, as a consequence, it has a low expression. The aim of this review is to give an overview on GSTP1 methylation studies with a special focus on liquid biopsy, thus to summarize methods, results, sample types, different diseases, to have a complete information regarding this promising epigenetic biomarker. We used all the most valuable scientific search engines (PubMed, Medline, Scopus and Web of Science) searching the following keywords: GSTP1, methylation, cancer, urine, serum, plasma and blood. GSTP1 is a largely investigated tissue biomarker in several malignancies such as prostate, breast, lung and hepatocellular carcinoma with good performances especially for diagnostic purposes. As a liquid biopsy biomarker, it has been mainly investigated in prostate cancer (PCa) where it showed a high specificity but a low sensitivity; thus, it is recommended in combination with other biomarkers. Despite the large number of published papers and the promising results, GSTP1 has not yet entered the clinical practice even for PCa diagnosis. For this reason, further large and prospective studies are needed to validate t...

Authors: Wang Y, Lan GB, Peng FH, Xie XB Abstract Renal transplantation is associated with an increased risk of cancers at multiple sites; however, the relationships between increased cancer risk and participant characteristics remain unclear. We searched PubMed, Embase, and the Cochrane Library to identify prospective observational studies performed up to July 2017. Totally 11 prospective studies reported data on 79,988 renal transplant recipients were included. Renal transplant recipients were found to display a higher risk of all cancers (standard incidence ratio [SIR]: 2.89; 95% CI: 2.13-3.91; P

heng Luo Kai Chen SET7, serving as the only histone methyltransferase that monomethylates ‘Lys-4’ of histone H3, has been proved to function as a key regulator in diverse biological processes, such as cell proliferation, transcriptional network regulation in embryonic stem cell, cell cycle control, protein stability, heart morphogenesis and development. What′s more, SET7 is involved inthe pathogenesis of alopecia aerate, breast cancer, tumor and cancer progression, atherosclerosis in human carotid plaques, chronic renal diseases, diabetes, obesity, ovarian cancer, prostate cancer, hepatocellular car...

s The notion that androgens and androgen receptor (AR) signaling are the hallmarks of prostate cancer oncogenesis and disease progression is generally well accepted. What is more poorly understood is the role of AR signaling in other human malignancies. This special issue of Cancers initially reviews the role of AR in advanced prostate cancer, and then explores the potential importance of AR signaling in other epithelial malignancies. The first few articles focus on the use of novel AR-targeting therapies in castration-resistant prostate cancer and the mechanisms of resistance to novel antiandrogens, and they also outl...

Authors: Gupta G, Chellappan DK, de Jesus Andreoli Pinto T, Hansbro PM, Bebawy M, Dua K Abstract MicroRNAs (miRNAs) are noncoding RNAs of around 20-25 nucleotides in length with highly conserved characteristics. They moderate posttranscriptional silencing by precisely combining with 3' untranslated regions (UTRs) of target mRNAs at a complementary site. miR503, an associate of the "canonical" miRNA16 family, is expressed in numerous types of tumors such as breast cancer, prostate cancer, lung cancer, colorectal cancer, hepatocellular carcinoma, glioblastoma and several others. There is convincing evidence...

Conclusion Smoking, infectious agents, and betel nut chewing appear to be important contributors to the burden of cancer in Guam. Earlier onset of cancer in Guam suggests earlier age of exposure to key risk factors and/or a more aggressive pathogenesis. Contrasting cancer patterns within Guam and between Guam and Hawaii underscore the potential influence of genes, lifestyle, and environmental factors on cancer development and progression.

Statins, 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors, are used to lower blood cholesterol levels and to prevent cardiovascular disease and related mortality [1]. Statin use has been suggested to have a beneficial effect on multiple cancer types, including colon cancer, breast cancer, and prostate cancer [2,3]. Inhibition of HMG-CoA reductase by statin in the rate limiting step in cholesterol synthesis controls the production of mevalonate and downstream metabolites that were recently identified to be involved in growth and apoptosis in many cancer types [4].

Two new coordination polymers, namely [Me3Sn(INA)] (CP1) and [Me3Sn(NA)] (CP2), where INA = isonicotinic acid and NA = nicotinic acid, were characterized using infrared, UV–visible and NMR spectroscopies, thermogravimetric analysis and single‐crystal X‐ray analyses. The structure of CP1 consists of a one‐dimensional coordinated chain which is further extended creating a two‐dimensional layer via hydrogen bonds. The two‐dimensional layers propagate along the corresponding planes creating a three‐dimensional framework by hydrogen bonding and edge‐to‐face π–π stacking. The...

The new synthesized supramolecular complexes (SC); [Cu2(CN)4(Et3Sn)2(tbpe)], 1 and [Cu2(CN)3(Et3Sn)(bpe)], 2 (tbpe = trans‐1,2‐bis(4‐pyridyl)ethene and bpe = 1,2‐bis(4‐pyridyl)ethane), were characterized by elemental analyses, electrical conductance, spectroscopic studies and thermal analyses. UV–Vis spectra and magnetic moment data suggested the tetrahedral geometry around Cu(I) atoms. The structures of the SC 1 and 2 were also theoretically studied using molecular mechanics (MM+). The structures were minimized with a semi‐empirical (PM3) method. The organotin compounds represent sign...

Conclusions: In this cohort of women with elevated risk, high serum 25(OH)D levels and regular vitamin D supplement use were associated with lower rates of incident, postmenopausal breast cancer over 5 y of follow-up. These results may help to establish clinical benchmarks for 25(OH)D levels; in addition, they support the hypothesis that vitamin D supplementation is useful in breast cancer prevention. https://doi.org/10.1289/EHP943 About This Article Received: 09 August 2016 Revised: 23 January 2017 Accepted: 06 February 2017 Published: 06 July 2017 Address correspondence to C.
