In the present study, a novel monoclonal antibody (MAb) specific for icariin (ICA) was prepared and characterized. A hybridoma‑secreting MAb against icariin was produced by fusing splenocytes immunized with an ICA‑bovine serum albumin conjugate with a hypoxanthine‑aminopterin‑thymidine‑sensitive mouse myeloma SP2/0 cell line. The antibody showed high specificity for ICA with almost no cross‑reactivity against the majority of structurally‑related chemicals. Subsequently, an indirect competitive enzyme‑linked immunosorbent assay (ELISA) for ICA was established and characterized...

Vascular endothelial growth factor (VEGF) inhibition has been demonstrated to be an effective strategy in preserving the integrity of the blood-brain barrier (BBB) in patients with acute ischemic stroke. Loss of the BBB is the key event associated with morbidity and mortality in these patients. However, the underlying mechanisms remain poorly understood. In the present study, the effects of VEGF inhibition and the possible mechanism that underlies acute cerebral ischemia in rats was investigated. Following the induction of transient middle cerebral artery occlusion for a 90‑min period, either an anti‑VEGF neutralizing antibody (RB‑222; 5 or 10 µg), or IgG (control), was administered by intracerebroventricular injection at 1 h following reperfusion...

Disseminated soft tissue sarcomas (STS) present a therapeutic dilemma. The first-line cytostatic doxorubicin demonstrates a response rate of 30% and is not suitable for elderly patients with underlying cardiac disease, due to its cardiotoxicity. Well‑tolerated alternative treatment options, particularly in palliative situations, are rare. Therefore, the present study assessed the anti‑proliferative effects of the natural compounds epigallocatechin-3-gallate (EGCG), silibinin and noscapine on STS cells. A total of eight different human STS cell lines were used in the study: Fibrosarcoma (HT1080), liposarcoma (SW872, T778 and MLS‑402), synovial sarcoma (SW982, SYO1 and 1273) and pleomorphic sarcoma (U2197)...

It is known that inhaled anesthetics induce neuroinflammation and facilitate postoperative cognitive dysfunction (POCD) in aged individuals; however, the mechanisms by which they mediate these effects remain elusive. Inhalation of the isoflurane anesthetic leads to opening of the mitochondrial permeability transition pore and loss of mitochondrial membrane potential. Therefore, mitochondrial retrograde signaling, which is an adaptive mechanism that facilitates the transmission of signals from dysfunctional mitochondria to the nucleus to activate target gene expression, may be activated during isoflurane inhalation...

Nonalcoholic fatty liver disease (NAFLD) is a common chronic liver disease, the pathological process of which is complex. Activation of the c‑Jun N‑terminal kinase (JNK) signaling pathway is associated with the mechanism underlying obesity-induced insulin resistance. Furthermore, the JNK signaling pathway and dysfunctional autophagy serve important roles in hepatic lipid metabolism. However, the exact role of JNK in autophagy and obesity‑induced insulin resistance is not fully understood. Therefore, the present study aimed to investigate the underlying mechanisms by which the JNK signaling pathway regulates autophagy and insulin resistance in fatty liver...

Arachidonic acid (AA) can be metabolized into 20-hydroxyeicosatetraenoic acid (20-HETE) by ω-hydroxylases, and epoxyeicosatrienoic acids (EETs) by epoxygenases. The effects of EETs in cardiovascular physiology are vasodilatory, anti-inflammatory and anti‑apoptotic, which are opposite to the function to 20‑HETE. However, EETs are not stable in vivo, and are rapidly degraded to the biologically less active metabolites, dihydroxyeicosatrienoic acids, via soluble epoxide hydrolase (sEH). Western blotting, reverse transcription‑quantitative polymerase chain reaction and liquid chromatography tandem mass spectrometry were performed in order to determine target RNA and protein expression levels...

Borna disease virus (BDV) is a neurotropic RNA virus that infects the limbic system of mammals and results in behavioral disorders. The hippocampus is a core region in the limbic system, which contributes to memory and learning and is important in the regulation of emotion. However, no validated microRNA housekeeping genes have yet been identified in BDV‑infected rat primary hippocampal neurons. Proper normalization is key in accurate miRNA expression analysis. The present study used reverse transcription‑quantitative polymerase chain reaction (RT‑qPCR) to evaluate the expression stability of 10 commonly used reference genes [miR‑92a, 5S, U6, miR‑103, miR‑101a, miR-let-7a, miR‑16, E2 small nucleolar RNA (snoRNA), U87 and miR‑191] in BDV‑infected rat hippocampal neurons and non‑infected controls across 12 days post‑infection...
