Targeted and immune-based therapies have improved outcomes in advanced kidney cancer, yet novel strategies are needed to extend the duration of these benefits and expand them to more patients. Combined inhibition of vascular endothelial growth factor (VEGF) and the programmed death 1 (PD-1)/programmed death ligand 1 (PD-L1) pathways with therapeutic agents already in clinical use may offer such a strategy. Here, we describe the development and clinical evaluation of VEGF inhibitors and, separately, PD-1/PD-L1 inhibitors...

A series of organometallic Au(I) N-heterocyclic carbene (NHC) complexes was synthesized and characterized on anticancer activity in four human cancer cell lines. The compounds' toxicity in healthy tissue was determined using precision cut kidney slices (PCKS) as a tool to determine the potential selectivity of the Au complexes ex vivo. All evaluated compounds presented cytotoxic activity towards the cancer cells in the nano- or low micromolar range. The mixed Au(I) NHC complex - (ter-butylethynyl)-1,3-bis-(2,6-diisopropylphenyl)-imidazol-2-ylidene gold(I), bearing an alkynyl moiety as ancillary ligand, showed high cytotoxicity in cancer cells in vitro, while being barely toxic in healthy rat kidney tissues...

Extensive research on the E2F transcription factor family has led to numerous insights that E2Fs were involved not only in proliferation and tumorigenesis but also in apoptosis and differentiation. In the present study, we analyzed the differential expression of E2Fs1-3 genes, and also evaluated the impact of E2Fs 1-3 genes expression on clinical outcome from the Cancer Genome Atlas (TCGA) database. The results showed that E2F1, E2F2 and E2F3 expression was increased in KIRC tissues than matched normal tissues (E2F1, P < 0...

Our meta-analysis published in 2010 provided evidence that low levels of serum albumin (hypoalbuminemia) are a significant independent predictor of acute kidney injury (AKI) and death following AKI. Since then, a large volume of additional data from observational clinical studies has been published further evaluating the relationship between serum albumin and AKI occurrence. This is an updated review of the literature to re-evaluate the hypothesis that hypoalbuminemia is independently associated with increased AKI risk...

Bioluminescence imaging (BLI) is an established method for evaluating metastatic load in preclinical cancer models; however, BLI can produce observational error due to differences in substrate concentration and signal depth. In our syngeneic murine model of metastasis (VM-M3), we used a quantitative polymerase chain reaction (qPCR) method of DNA quantification to bypass these limitations. Liver, spleen, and brain from VM/Dk (VM) mice bearing VM-M3 tumor cells were first imaged ex vivo with BLI. qPCR quantification of tumor cell DNA was then performed on DNA extracted from these organs...

Curcumin is a dominating active component of curcuma longa and has been studied widely because of its prominent biological activities. Extremely low aqueous solubility, stability and bioavailability of curcumin limits its application in the field of medicine. In this study, we developed pectin-curcumin (PEC-CCM) conjugates which could self-assemble water-soluble nano-micelles in aqueous solution. The structure of PEC-CCM conjugates was characterized by ultraviolet and visible spectra (UV-Vis), fluorescence spectra, Fourier transform infrared (FTIR) spectroscopy and 1H nuclear magnetic resonance (NMR) spectroscopy...
