Methotrexate (MTX) is a classical chemotherapeutic agent with nephrotoxicity as the most disturbing adverse effect. So far, its underlying molecular mechanisms, particularly PI3K/Akt/eNOS transduction, are inadequately explored. Several antioxidant modalities have been characterized to ameliorate MTX-induced renal injury. In this regard, Camel milk (CM) is a natural product with recognized antioxidant and anti-inflammatory features. Thus, the current study aimed to investigate the potential ameliorating effects of CM in MTX-induced kidney injury in rats...

The population of cancer survivors with prior cancer is rapidly growing. Whether a prior cancer diagnosis interferes with outcome is unknown. We conducted a pan-cancer analysis to determine the impact of prior cancer history for patients newly diagnosed with cancer. We identified 20 types of primary solid tumors between 2004 to 2008 in the Surveillance, Epidemiology, and End Results (SEER) database. Demographic and clinicopathologic variables were compared by chi-squared test and t-test as appropriate. The propensity score-adjusted Kaplan-Meier method and Cox proportional hazards models were used to evaluate the impact of prior cancer on overall survival (OS)...

A 74-year-old man presented to the Andrology Clinic for management of potential complications of androgen deprivation therapy for prostate cancer. He had a rising prostate-specific antigen with a concurrent rise in alkaline phosphatase and bone remodeling markers. This was despite treatment with a radical prostatectomy, androgen deprivation, and anti-resorptive therapy. A follow-up dual-energy X-ray absorptiometry scan revealed a marked increase in his bone mineral density at both the lumbar spine and femoral neck...

Background: Risk factors for poststroke falls and fractures remain poorly understood. This study aimed to evaluate which factors increased risk of these events after stroke. Methods: Data from 7,267 hospitalized stroke patients were acquired from the Norfolk and Norwich University Hospital Stroke Register from 2003-2015. The impacts of multiple patient level and stroke characteristics and comorbidities on post-discharge falls and fractures were assessed. Univariate and multivariable models were constructed, adjusting for multiple confounders, using binary logistic regression for short-term analysis (up to 1-year post-discharge) and Cox-proportional hazard models for longer term analysis (1-3, 3-5, and 0-10 years follow-up)...

Epidermal growth factor receptors (EGFRs) and their cytoplasmic tyrosine kinases play significant roles in cell proliferation and signaling. All the members of the EGFR/ErbB family are primary goals for cancer therapy, particularly for tumors of breast, cervix, ovaries, kidney, esophagus, prostate and non-small-cell lung carcinoma and head and neck tumors. However, the therapeutic ability of accessible anti-ErbB agents is limited. Therefore, recognizing EGF analogues or small organic molecules with high affinity for the extracellular domain of the EGFR is a critical target on cancer research...

Renal cell carcinoma (RCC), a malignancy whose incidence is increasing, is frequently encountered in general nephrology practice when acute and chronic kidney disease occurs in the course of disease. Importantly, when kidney disease develops in the setting of RCC, mortality is significantly increased with patients often dying of a non-cancer-related complication of kidney disease. As such, practicing nephrologists need to have a working knowledge of this cancer's biology, treatment, and complications. Nephrologists should be involved in all aspects of the care of patients with RCC including in the acute setting prior to nephrectomy and in the chronic setting for patients with post-nephrectomy chronic kidney disease and those receiving potentially nephrotoxic anti-cancer agents...

BACKGROUND: Selenoproteins (25 genes in human) co-translationally incorporate selenocysteine using a UGA codon, normally used as a stop signal. The human selenoproteome is primarily regulated by selenium bioavailability with a tissue-specific hierarchy. METHODS: We investigated the hierarchy of selenoprotein expression in response to selenium concentration variation in four cell lines originating from kidney (HEK293, immortalized), prostate (LNCaP, cancer), skin (HaCaT, immortalized) and liver (HepG2, cancer), using complementary analytical methods...

BACKGROUND: The evaluation of chronic kidney disease in cancer patients seems to rely mostly on the Cockcroft-Gault (CG) formula or the creatinine levels to adjust treatment dosages which is a practice refuted by internists. AIMS: We evaluate the overall agreement of the CG, MDRD and CKD-EPI equation with the newly devised Janowitz and Williams' (JW) equation. METHODS: The renal function was estimated in 235 cancer patients according to the CG, MDRD, body surface area (BSA)-adjusted MDRD, CKD-EPI, BSA-adjusted CKD-EPI and JW formulae...

Mixed epithelial and stromal tumor of the kidney (MESTK) is a rare renal tumor composed of solid and cystic components. Mixed epithelial and stromal tumor of the kidney has no pathognomonic imaging feature. It is difficult to distinguish MESTK from other cystic renal neoplasms using current radiological methods. We report a rare case of MESTK that was diagnosed in a 46-year-old woman with breast cancer. F-FDG PET/CT and contrast-enhanced CT features of MESTK are presented, which could potentially provide useful information in the differential diagnoses of cystic renal neoplasms...

CD44v6 is overexpressed in a variety of cancers, rendering it a promising target for radio-immunotherapy (RIT). In this study, we have characterized a novel engineered recombinant monoclonal anti-CD44v6 antibody, AbN44v6, and assessed its potential for use in RIT using either 177Lu or 131I as therapeutic radionuclides. In vitro affinity and specificity assays characterized the binding of the antibody labeled with 177Lu, 125I or 131I. The therapeutic effects of 177Lu-AbN44v6 and 131I-AbN44v6 were investigated using two in vitro 3D tumor models with different CD44v6 expression...

Vitamin D is a key signalling molecule that plays a vital role in the regulation of calcium-phosphate homeostasis and bone remodelling. The circulating biologically active form of vitamin D is regulated by the catabolic mechanism of cytochrome P450 24-hydroxylase (CYP24A1) enzyme. The over-expression of CYP24A1 negatively regulates the vitamin D level, which is the causative agent of chronic kidney disease, osteoporosis, and several types of cancers. In this study, we found three potential lead molecules adverse to CYP24A1 through structure-based, atom-based pharmacophore and e-pharmacophore-based screening methods...

Renal cell carcinoma (RCC) is the most prevalent and lethal malignancy of the kidney. Despite all the efforts made, no tissue biomarker is currently used in the clinical management of patients with kidney cancer. A search for possible biomarkers in urine for clear cell renal cell carcinoma (ccRCC) has been conducted. Non-targeted metabolomic analyses were performed on paired samples of surgically removed renal cancer and normal tissue, as well as on urine samples. Extracts were analyzed by liquid chromatography/high-resolution mass spectrometry (LC-HRMS)...

Vitamin D, traditionally known as an essential nutrient, is a precursor of a potent steroid hormone that regulates a broad spectrum of physiological processes. In addition to its classical roles in bone metabolism, epidemiological, preclinical, and cellular research during the last decades, it revealed that vitamin D may play a key role in the prevention and treatment of many extra-skeletal diseases such as cancer. Vitamin D, as a prohormone, undergoes two-step metabolism in liver and kidney to produce a biologically active metabolite, calcitriol, which binds to the vitamin D receptor (VDR) for the regulation of expression of diverse genes...

Aristolochic acid I (AAI) is a phytocompound that is linked to the progressive renal disease and development of human urothelial carcinoma. The bladder cancer-associated protein (BLCAP) gene exhibits a tumor suppressor function in various tumors, including bladder carcinoma. This study evaluated the effect of AAI on BLCAP expression and its associated mechanism in human cells. Administering AAI to human embryonic kidney cells (HEK293), human proximal tubule epithelial cells (HK-2) and urinary bladder cancer cells (HT-1376) significantly reduced the expression of BLCAP mRNA and protein...

Glu-Urea-Lys (GUL) derivatives have been reported as prostate-specific membrane antigen (PSMA) agent. We developed derivatives of GUL conjugated with NOTA or DOTA via a thiourea linker and tested their feasibility as PSMA imaging agents after labeling with 68 Ga. NOTA-GUL and DOTA-GUL were synthesized and labeled with 68 Ga using generator-eluted 68 GaCl3 in 0.1 M HCl in the presence of 1 M NaOAc at pH 5.5. The stabilities of 68 Ga-labeled compounds in human serum were tested at 37.5 °C. A competitive binding assay was performed using the PSMA-positive prostate cancer cell line 22Rv1 and [125 I]MIP-1072 (PSMA-specific binding agent) as a tracer...

Nanoparticle-based tumor therapies are extensively studied; however, few are capable of improving patient survival time due to premature drug leakage, off target effects, and poor tissue penetration. Previously, we successfully synthesized a novel family of Y1 receptor (Y1 R) ligand modified, photoluminescent BPLP nanobubbles and nanoparticles for targeted breast cancer ultrasound imaging; however, increased accumulation could also be observed in the liver, kidney, and spleen, suggesting significant interaction of the particles with macrophages in vivo...
