Apoptosis; Invasion; miR-181b; PC-3; Proliferation; Prostate cancer

We examined microRNA-181b (miRNA) expression in prostate cancer tissues and its effect on the prostate cancer cell line PC-3. Tissues from 27 cases of prostate cancer and 30 samples of normal human prostate were collected by surgical removal. Total miRNA was extracted, and the relative expression of miR-181b was quantified using RT-PCR. miR-181b ASO was transfected into prostate cancer PC ... more

14-3-3 Proteins; Antioxidant; Apoptosis; Glioma; Heat shock protein 27 (Hsp27); Viscum album

Extracts of mistletoe (Viscum album) are intensively used in complementary medicine, but their mechanisms are not fully understood in most cases, and the effects on metabolism have not been investigated in detail. However, some biologically active natural products are well known to provoke unexpected cellular responses. They reduce overexpression of heat shock proteins (Hsps) in ... more

Apoptosis; Fusion protein; hA20; High glucose; HUVECs; Protein transduction domain

We constructed a plasmid containing a protein transduction domain (PTD) and a human A20 (hA20) gene fragment; the fusion protein was obtained by highly expressing this plasmid in the yeast Pichia pastoris GS115. The plasmid was obtained by adding 9xArg and EcoRІ recognition sites to the end of the primer, and 6xHis-Tag and NotІ recognition sites to its end. ... more

Apoptosis; Atorvastatin; Cerebral ischemia and reperfusion; Cytochrome C; Mitochondrial permeability transition pore

The aim of this study was to investigate the influence of atorvastatin on the opening of the mitochondrial permeability transition pore (MPTP) and the expression of cytochrome C (Cyt C) in Sprague-Dawley rats with cerebral ischemia-reperfusion (I/R). The rat model of cerebral artery ischemia was established by the suture-occluded method with ischemia for 2 h and reperfusion for 72 h. ... more

Apoptosis; Cytochalasin B; Glioma; mitosis

Cytochalasin B (CB) is known to inhibit a number of cancer types, but its effects on gliomas are unknown. We examined the in vitro effects of CB on the proliferation of human glioma U251 cells, as well as determined its mechanism of action. Cell proliferation was determined using CCK-8. The effect of CB on U251 cell morphology was observed under a transmission electron microscope ... more

Antigenotoxicity; Apoptosis; Necrosis; Tephrosia cinerea

Tephrosia cinerea L. (Pers.) is a tropical species that exhibits antileishmanial activity in Leishmania amazonensis promastigote cultures and is commonly used to treat infections, inflammations, ulcers, nervous conditions, and diarrhea. However, no studies have investigated its effects on genetic material. Therefore, we evaluated the genotoxic potential, antigenotoxic ... more

Apoptosis; Gastric cancer; Small interfering RNA; Survivin

A pair of inverted repeated sequences of the gene survivin was designed for stable double-stranded RNA establishment. After stable transfection, the biological behaviors of gastric cancer cells were observed. The interference rates of survivin-targeting siRNA (siRNA-survivin) in BGC823, MKN45, SGC7901, and cisplatin-resistant SGC7901 groups were 55.363 ± 3.974 ... more

Acrylonitrile; Apoptosis; Brain neuron; Neuron morphology; Rat

This study aimed to evaluate the effects of acrylonitrile (ACN) on neuronal morphology and apoptosis in rats. An ACN solution was administered to Wistar rats by gavage at doses of 0, 5, 10, or 20 mg/kg, 5 days a week for 13 weeks. The morphology of neurons and the presence of apoptosis was examined by light and electron microscope, DNA electrophoresis, immunohistochemistry, and terminal ... more

Apoptosis; Guanine nucleotide-binding protein; Pig; Thyroid gland

The Alpha subunit of the stimulatory guanine nucleotide-binding protein (GNAS) is a complex imprinted gene. The major product of the GNAS gene is the α-subunit of the guanine nucleotide-binding protein (Gas), which plays a key role in multiple signal transduction pathways. Gas is required for the production of the receptor-stimulated intracellular cyclic adenosine monophosphate ( ... more

Apoptosis; Aspirin; Proliferation; Thy-1; Wnt/β-catenin

Cancer stem cells have been found to play important roles in carcinoma. Although thy-1 has been identified as a potential stem cell marker of liver cancer, whether the Wnt/β-catenin signaling pathway plays an important role in regulating hepatocarcinoma proliferation and apoptosis mediated by thy-1 remains unknown. Our results showed that high thy-1 expression caused hepG2 cells ... more
