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...

Resection of completely endophytic renal tumors is a huge challenge for surgeons due to a lack of definite visual clues, especially in the laparoscopic approach. Three-dimensional (3D) kidney models, which can illustrate the clear relationship between renal masses and surrounding health tissues, were considered as reliable tools for understanding renal tumor characteristics in previous studies. We hypothesized that 3D kidney models can be used not only for planning but also for navigating laparoscopic partial nephrectomy (LPN) in patients with completely endophytic renal tumors...

BACKGROUND & AIMS: Since the first account of the myth of Prometheus, the amazing regenerative capacity of the liver has fascinated researchers due to its enormous medical potential. Liver regeneration is promoted by multiple types of liver cells, including hepatocytes and liver non-parenchymal cells (NPCs), through the complex intercellular signaling. However, the liver organogenetic mechanism, especially the role of adult hepatocytes at ectopic sites, remains unknown. In this study, we demonstrate that hepatocytes alone spurred liver organogenesis to form an organ-sized complex 3D liver that exhibited native liver architecture and functions in the kidneys of mice...

Porcine sapelovirus (PSV) is a causative agent of neurological disorders, fertility disorders and dermal lesions of swine. In this study, we isolated two PSV strains, Jpsv477 and Jpsv1315, from swine faecal specimens using a PLC/PRF/5 cell culture system. The PSV infection of PLC/PRF/5 cells induced a cytopathic effect (CPE). Two types of virus particles with identical diameter (~35 nm) but different densities (1.300 and 1.285 g/cm3 ) were observed in the cell culture supernatants. Analysis of the entire genome sequence of Jpsv477 and Jpsv1315 revealed that both strains possess 7,558 nucleotides and the poly (A) tail and have a typical PSV genome organization consisting of a 5' terminal untranslated region (5'UTR), a large open reading frame (ORF), and a 3' terminal untranslated region (3'UTR)...

Fatty acid desaturase (Fads) and elongase (Elovl) are two important enzymes involved in the biosynthesis of long-chain polyunsaturated fatty acids (LC-PUFAs) in fishes. Silver barb (Puntius gonionotus) is considered a promising medium carp species for freshwater aquaculture in Asia. Earlier, Δ6 fads cDNA was characterized to understand the molecular mechanism of LC-PUFA biosynthesis in this species. In the present study elovl5-like elongase full-length cDNA was cloned and characterized by RACE (rapid amplification of cDNA ends), and analyzed its basal expression in various organs/tissues by quantitative real time PCR (qRT-PCR) assay...

Cytokinesis mediates the physical separation of dividing cells and, in 3D epithelia, provides a spatial landmark for lumen formation. Here, we unravel an unexpected role in cytokinesis for proteins of the intraflagellar transport (IFT) machinery, initially characterized for their ciliary role and their link to polycystic kidney disease. Using 2D and 3D cultures of renal cells, we show that IFT proteins are required to correctly shape the central spindle, to control symmetric cleavage furrow ingression and to ensure central lumen positioning...

The aim of this study was to characterize the in vivo volumetric distribution of three folate-based biosensors by different imaging modalities (X-ray, fluorescence, Cerenkov luminescence, and radioisotopic imaging) through the development of a tridimensional image reconstruction algorithm. The preclinical and multimodal Xtreme imaging system, with a Multimodal Animal Rotation System (MARS), was used to acquire bidimensional images, which were processed to obtain the tridimensional reconstruction. Images of mice at different times (biosensor distribution) were simultaneously obtained from the four imaging modalities...

Background: Medullary cystic kidney disease Type 1 is an autosomal dominant tubulointerstitial kidney disease (ADTKD). Recently, mucin 1 (MUC1) was identified as a causal gene of medullary cystic kidney disease (ADTKD-MUC1). However, the MUC1 mutation was found to be a single cytosine insertion in a single copy of the GC-rich variable number of tandem repeats (VNTRs), which are very difficult to analyze by next-generation sequencing. To date, other mutations have not been detected in ADTKD-MUC1, and the mutant MUC1 protein has not been analyzed because of the difficulty of genetically modifying the VNTR sequence...

Metabolism is a compartmentalized process, and it is apparent in studying cancer that tumors, like normal tissues, demonstrate metabolic cooperation between different cell types. Metabolic profiling of cells in 2D culture systems often fails to reflect the metabolism occurring within tissues in vivo due to lack of other cell types and 3D interaction. We designed a tooling and methodology to metabolically profile and compare 2D cultures with cancer cell spheroids, and microtissue slices from tumors, and normal organs...

WAY-267,464 (1) and twelve conformationally rigid analogues (3a-f-4a-f) were synthesised, characterised and evaluated in cellular assays with the aim of systematically exploring interactions with the oxytocin receptor (OTR). Each analogue was evaluated in radioligand binding displacement assays at both human OTR and arginine vasopressin 1a receptors (V1aR). Physiological characterisation was determined by whole cell IP1 accumulation assays on stably transfected human embryonic kidney (HEK) cells. Incorporation of the rigid, optionally substituted benzene ring abolished OTR activity and diminished V1aR pharmacology when compared to 1...

Using an innovative, tissue-independent approach to decellularized tissue processing and biomaterial fabrication, the development of a series of "tissue papers" derived from native porcine tissues/organs (heart, kidney, liver, muscle), native bovine tissue/organ (ovary and uterus), and purified bovine Achilles tendon collagen as a control from decellularized extracellular matrix particle ink suspensions cast into molds is described. Each tissue paper type has distinct microstructural characteristics as well as physical and mechanical properties, is capable of absorbing up to 300% of its own weight in liquid, and remains mechanically robust (E = 1-18 MPa) when hydrated; permitting it to be cut, rolled, folded, and sutured, as needed...
