An asymmetric potato hybrid and its parental lines were cytogenetically examined. DAPI (4'-6-diamidino-2-phenylindole) staining was used to count chromosomes in all analysed lines and revealed the presence of minichromosomes in the hybrid genome. Fluorescent in situ hybridization (FISH) with rDNA sequence as a probe helped to determine the ploidy level of analysed lines and revealed that none o...
Background: Recent studies conducted by us indicate that aloin (ALO) could promote gastric cancer (GC) cell apoptosis, but the underlying mechanism remains unclear. The high mobility group box 1 (HMGB1) has been reported to regulate proliferation, and migration of several types. Bioinformatics analysis suggests a possible targeted regulatory relationship between miR5683 HMGB1. Purpose: Herein, ...
rho 0 HeLa cells entirely lacking mitochondrial DNA (mtDNA) and mitochondrial transfection techniques were used to examine intermitochondrial interactions between mitochondria with and without mtDNA, and also between those with wild-type (wt) and mutant-type mtDNA in living human cells. First, unambiguous evidence was obtained that the DNA-binding dyes ethidium bromide (EtBr) and 4',6-diamidino...
Background: Colorectal Cancer (CRC) is the most common malignant gastrointestinal cancer. stem cells (CSCs) are major cause of cancer recurrence and drug resistance. Silibinin, as an herbal compound, has anticancer properties. Objectives: The present study aimed to evaluate antiproliferative effects silibinin on HT29 stem-like (spheroids). Methods: In this study, apoptotic properties Silibinin ...
We study the nonlinear optical properties of lithium niobate (LiNbO(3)) nanowires (NWs) fabricated by a top-down ion beam enhanced etching method. First, we demonstrate generation and propagation of the second-harmonic (SH) light in LiNbO(3) NWs of typical rectangular cross-sections of 400 x 600 nm(2) and length from 10 to 50 μm. Then, we show local fluorescent excitation of 4',6-diamidino-2-ph...
Multidrug and toxin extrusion protein 1 (MATE1) and MATE2-K are organic cation/H(+) antiporters that have recently been identified and suggested to be responsible for the brush border secretory transport of many cationic drugs in renal tubules. We here report our finding that 4',6-diamidino-2-phenylindole (DAPI) can be used as a probe substrate for rapid assays of the functionality of the human...
Single-cell cell cycle analysis is an emerging technique that requires detailed exploration of the image analysis process. In this study, we established a microfluidic single-cell cell cycle analysis method that can analyze cells in small numbers and in situ on a microfluidic chip. In addition, factors that influenced the analysis were carefully investigated. U87 or HeLa cells were seeded and a...
Apoptosis of vascular smooth muscle cells (VSMCs) is of importance in the development of diabetic angiopathy. Our aim was to evaluate the effect of insulin and IGF-I on apoptosis in VSMCs. Rat aortic VSMCs were used and apoptosis was induced by serum starvation. As apoptotic markers we measured caspase-3 activity, histone-associated DNA fragments by ELISA and nuclear morphology by DAPI (4',6-di...
Fluorescence-activated cell sorting (FACS) is a laser-based, biophysical technology that allows simultaneous multiparametric analysis. For the analysis of dying cells, fluorescently labeled Annexin V (Annexin V(FITC)) and propidium iodide (PI) are the most commonly used reagents. Instead of PI, 4',6-diamidino-2-phenylindole (DAPI) can also be used. DAPI is a fluorescent stain that binds strongl...
