Newly synthesised mononuclear gold complexes containing the 2-BrC6F4PPh2 ligand have been fully characterised and their anticancer activity towards five human tumor [prostate (PC3), glioblastoma (U87MG), cervical (HeLa), fibrosarcoma (HT1080), ovarian (SKOV-3)] and normal human embryonic kidney (Hek-293T) cell lines investigated. Some of the synthesised gold complexes displayed higher cytotoxicity than cisplatin towards PC-3, HeLa and U87MG cells and inhibited the thioredoxin reductase (TrxR) enzyme, which is considered a potential target for new compounds in cancer treatment...

Dipeptidyl peptidase 4 (DPP4), also known as CD26 is a type II transmembrane protein that is released from the cell membrane in a nonclassical secretory mechanism. This exopeptidase selectively degrades varieties of substrates including incretin hormones, growth factors, and cytokines. A significant detectable amount of DPP4 activity can be measured in plasma as well as in different tissues such as intestinal epithelium, vascular endothelium, lymphocytes, monocytes, kidney, liver, adipose, lung, thymus, spleen, prostate, etc...

The Tumor-Node-Metastasis (TNM) classification on cancer staging, jointly developed by the American Joint Commission on Cancer (AJCC) and the Union for International Cancer Control (UICC), has been updated to its 8th edition with two contemporaneous versions published by the AJCC and UICC. While the goal of the AJCC and UICC is to have identical TNM staging systems, differences exist between these two publications including in the staging of urologic cancers. Among several new facets in the AJCC staging manual, a select few of greater import include an expanded section on imaging, presentation of levels of evidence for significant changes, and endorsement of risk assessment models that pass the AJCC quality criteria such as in prostate cancer...

Bone is one of the most preferential target site for cancer metastases, particularly for prostate, breast, kidney, lung and thyroid primary tumours. Indeed, numerous chemical signals and growth factors produced by the bone microenvironment constitute factors promoting cancer cell invasion and aggression. After reviewing the different theories proposed to provide mechanism for metastatic progression, we report on the gene expression profile of bone-seeking cancer cells. We also discuss the cross-talk between the bone microenvironment and invading cells, which impacts on the tumour actions on surrounding bone tissue...

Identifying new druggable targets is desired to meet the needs for effective cancer treatments. To this end, we previously reported the efficacy of a therapeutic peptide called CT20p that displays selective cytotoxicity through inhibition of a multi-subunit, protein-folding complex called Chaperonin-Containing TCP-1 (CCT). To investigate the role of CCT in cancer progression, we examined protein levels of CCT subunits in liver, prostate, and lung cancer using human tissue microarrays. We found that these cancers expressed higher levels of CCT2 as compared to normal tissues...

Cisplatin, a platinum chelate with potent antitumor activity against cancers of the testis, ovary, urinary bladder, prostate, and head and neck, has adverse effects on the kidney, bone marrow, and digestive organs, and its use is particularly limited by nephropathy as a side effect. In the present study, safflower seed extract was administered to a mouse model of cisplatin-induced acute renal failure to investigate its activity. Cisplatin (20[Formula: see text]mg/kg body weight) was administered by intraperitoneal injection to mice that had received oral safflower seed extract (100 or 200[Formula: see text]mg/kg body weight per day) for the preceding 2 days...

OBJECTIVE: A highly sensitive and specific urine marker for the detection of recurrent urothelial cancer and for screening healthy population or people at risk for urothelial cancer has not been found yet. As urine cytology is not sensitive enough, patients with non-muscle-invasive bladder cancer need lifelong follow-up involving multiple invasive cystoscopies. Our aims of study were to examine the expression of semaphorin 3A in urothelial cancer patients and to evaluate semaphorin 3A as a potential marker for urothelial cancer...

BACKGROUND: Integrated delivery systems (IDSs) are postulated to reduce spending and improve outcomes through successful coordination of care across multiple providers. Nonetheless, the actual impact of IDSs on outcomes for complex multidisciplinary care such as major cancer surgery is largely unknown. METHODS: Using 2011-2013 Medicare data, this study identified patients who underwent surgical resection for prostate, bladder, esophageal, pancreatic, lung, liver, kidney, colorectal, or ovarian cancer...

NDRG1 (N-myc downstream-regulated gene 1) was previously considered to be a differentiation-related gene. However, many other functions of NDRG1 have since been identified, including proliferation, migration, invasion, and vascularization of tumor cells. Currently regarded as a tumor suppressor in most studies, NDRG1 is abundant in prostate, brain, kidney, placental, and intestinal tissues. It is expressed in normal endometrium, with higher expression occurring in the secretory phase. NDRG1 was first identified as an inhibitor of signaling pathways associated with the pathology of endometriosis...

BACKGROUND: Late metastases develop from cancer of the breast, prostate, lung, kidney and malignant melanomas. Memory T-cells have excellent potential to prevent this devastating development in the same way that they routinely prevent emergence of latent viruses. MATERIAL AND METHODS: A peritoneal tumor mouse model of viral oncotherapy was used to generate therapeutic antitumor memory T-cells. Functional in vivo and in vitro assays were used to study the temporal evolution of their anticancer effects...

B-mode ultrasound imaging is used extensively in medicine. Hence, there is a need to have efficient segmentation tools to aid in computer-aided diagnosis, image-guided interventions, and therapy. This paper presents a comprehensive review on automated localization and segmentation techniques for B-mode ultrasound images. The paper first describes the general characteristics of B-mode ultrasound images. Then insight on the localization and segmentation of tissues is provided, both in the case in which the organ/tissue localization provides the final segmentation and in the case in which a two-step segmentation process is needed, due to the desired boundaries being too fine to locate from within the entire ultrasound frame...

Focal incidental uptake, with or without CT abnormalities, is a common finding on FDG PET/CT and evidence based management for this type of uptake is lacking. This article reviews the evidence on focal incidental uptake including the incidence of malignancy, differential diagnosis and imaging criteria which can be used to further characterise it. The article focusses on PET rather than CT criteria. The strength of the evidence base is highly variable ranging from systematic reviews and meta-analyses to a virtual absence of evidence...

INTRODUCTION: To date, bilateral pelvic lymph node dissection (PLND) represents the most accurate and reliable staging procedure for the detection of lymph node invasion in prostate cancer and bladder cancer. However, the procedure is not devoid of complications. In this field, Indocyanine green fluorescence-guided sentinel lymph node (SLN) identification is an emerging and promising technique, as accurate staging of urologic cancer could be enhanced by a thorough evaluation of the sentinel lymph nodes...

Cadmium (Cd) is a heavy metal belonging to the group of the main chemical pollutants of the natural and occupational environment in economically developed countries. The forecasts indicate that contamination of the environment with this toxic metal, and thus the exposure of the general population, will increase. Food (particularly plant products) is the main source of the general population exposure to this element. Moreover, an important, and often the main, source of intoxication with Cd is habitual tobacco smoking...

Long non-coding RNAs (lncRNAs) are emerging as important players in regulation of gene expression in higher eukaryotes. DDX5/p68 RNA helicase protein which is involved in splicing of precursor mRNAs also interacts with lncRNAs like, SRA and mrhl, to modulate gene expression. We performed RIP-seq analysis in HEK293T cells to identify the complete repertoire of DDX5/p68 interacting transcripts including 73 single exonic (SE) lncRNAs. The LOC284454 lncRNA is the second top hit of the list of SE lncRNAs which we have characterized in detail for its molecular features and cellular functions...
