OBJECTIVE: Temporal lobe epilepsy (TLE) is a chronic epilepsy syndrome defined by seizures and progressive neurological disabilities, including cognitive impairments, anxiety and depression. Here, human TLE specimens were investigated focusing on the mechanistic target of rapamycin (mTOR) Complex 1 (mTORC1) and Complex 2 (mTORC2) activities in the brain, as both pathways may represent unique targets for treatment. METHODS: Surgically resected hippocampal and temporal lobe samples from therapy-resistant TLE patients were analyzed by Western blotting to quantify the expression of established mTORC1 and mTORC2 activity markers and upstream or downstream signaling pathways involving the two complexes...

Ischemic stroke is caused by a blockage of cerebral blood flow resulting in neuronal and glial hypoxia leading to inflammatory and reactive oxygen species (ROS)-mediated cell death. Nitric oxide (NO) formed by NO synthase (NOS) is known to be protective in ischemic stroke, however NOS has been shown to 'uncouple' under oxidative conditions to instead produce ROS. Nitrones are antioxidant molecules that are shown to trap ROS to then decompose and release NO. In this study, the nitrone 5was designed such that its decomposition product is a NOS inhibitor, 6, effectively leading to NOS inhibition specifically at the site of ROS production...

BACKGROUND: Chemoresistance is a major obstacle that limits the benefits of 5-Fluorouracil (5-Fu)-based chemotherapy for colon cancer patients. Autophagy is an important cellular mechanism underlying chemoresistance. Recent research advances have given new insights into the use of natural bioactive compounds to overcome chemoresistance in colon cancer chemotherapy. As one of the multitargeted and safer phytomedicines, curcumin has been reported to work as cancer-specific chemosensitizer, presumably via induction of autophagic signaling pathways...

This study aimed to evaluate the effect of ethyl acetate fraction (EAF) isolated from Molineria latifolia rhizome as dietary interventions for type 2 diabetes mellitus (T2DM) and its underlying molecular mechanisms in vivo. Experimental rats were induced by high fat diet feeding coupled with combined exposure to streptozotocin and nicotinamide. Treatment with EAF improved glucose tolerance and lipid profiles, but the insulin secretion was unaltered. Gene expression analyses on insulin/adipocytokine signalling-related genes demonstrated tissue-specific transcriptional responses...

Duvelisib (IPI-145) is an oral inhibitor of phosphoinositide-3-kinase (PI3K)-δ/γ isoforms currently in clinical development. PI3K-δ/γ inhibition may directly inhibit malignant T-cell growth, making Duvelisib a promising candidate for patients with peripheral (PTCL) or cutaneous (CTCL) T-cell lymphoma. Inhibition of either isoform may also contribute to clinical responses by modulating nonmalignant immune cells. We investigated these dual effects in a TCL cohort from a Phase 1, open-label study of Duvelisib in patients with relapsed or refractory PTCL [n=16] and CTCL [n=19], along with in vitro and in vivo models of TCL...

Diabetes is characterized by poor wound healing which currently lacks an efficacious treatment. The innate repair receptor (IRR) is a master regulator of tissue protection and repair which is expressed as a response injury or metabolic stress, including in diabetes. Activation of the IRR might provide benefit for diabetic wound healing. A specific IRR agonist cibinetide was administered in an incisional wound healing model performed mice with genetic diabetes (db+/db+) and compared to the normal wild-type. Animals were treated daily with cibinetide (30μg/kg/s...

Iron-overload cardiomyopathy is prevalent on a worldwide basis and is a major co-morbidity in patients with genetic hemochromatosis and secondary iron overload. Therapies are limited in part due to lack of a valid pre-clinical model, which recapitulates advanced iron-overload cardiomyopathy. Male hemojuvelin knockout (HJVKO) mice, which lack hemojuvelin (HJV), a bone morphogenetic co-receptor protein required for hepcidin expression and systemic iron homeostasis, were fed a high iron diet starting at 4 weeks of age for a duration of 1 year...

Diffuse intrinsic pontine glioma (DIPG) is an incurable childhood brain tumor. The mechanistic target of rapamycin (MTOR), a key oncogene, functions as two distinct signaling complexes, MTORC1 and MTORC2. We set out to determine the preclinical efficacy and mechanism of action of MTOR inhibitors in DIPG. We evaluated the MTORC1 inhibitor everolimus and the MTORC1/2 inhibitor AZD2014 in three patient-derived DIPG cell lines using cell culture models. We created dose-response curves for both compounds. We measured phenotypic effects on cell self-renewal, apoptosis, cell cycle, differentiation, senescence, and autophagy...

Autologous fat grafting procedures have noted a markedly increased frequency, not only for cosmetic purposes, but also for deformities after head and neck cancer and breast cancer surgery. Carcinogenesis is always a major concern in cell therapy-related issues. However, there is no literature discussing this issue in head and neck squamous cell carcinoma patients. To evaluate the interaction of tongue cancer cells and adipose-derived stem cells, we performed a series of in vitro experiments. Our results demonstrated that cisplatin significantly reduced the viabilities of SCC‑25 and CAL‑27 cells in a concentration-dependent manner, but it had low cytotoxicity in cisplatin-resistant CAL‑27 (CAR) cells...

Cardiac stem cells (CSCs) are important for improving cardiac function following myocardial infarction, with CSC migration to infarcted or ischemic myocardium important for cardiac regeneration. Strategies to improve cell migration may improve the efficiency of myocardial regeneration. Basic fibroblast growth factor (bFGF) is an essential molecule in cell migration, but the endogenous bFGF level is too low to be effective. The effect of exogenously delivered bFGF on CSC migration was observed in vitro and in vivo in the present study...

Sorafenib, a multikinase inhibitor for hepatocellular carcinoma treatment, inhibits the Raf/MAPK/ERK signaling pathway. However, PI3K/Akt signaling pathway is activated by Sorafenib and cross-talks with the Raf/MAPK/ERK signaling pathway, leading to drug resistance. 20(S)-Ginsenoside Rg3 has been reported with significant anticancer effect to numerous carcinomas by inhibition of PI3K-Akt signaling pathway. Hence, we aim to examine the synergistic anticancer activity of 20(S)-Ginsenoside Rg3 and Sorafenib via modulation of PTEN/Akt signaling pathway...

NF-κB pathway and p38MAPK (p38mitogen-activated protein kinase) pathway have been shown to play a key role in neuroinflammation, however, the phosphorylation modification is an important process that affects the activation of above pathways. Dual-specificity tyrosine-phosphorylation-regulated kinase 2(Dyrk2), as a phosphokinase that can phosphorylate signal molecules, has been demonstrated to regulate Type I Interferon(TIF) by promoting ser527 phosphorylation of TBK1. Therefore, to investigate the role of Dyrk2 in neuroinflammation, we analyzed the effect of Dyrk2 on LPS-induced the activation of microglia...

Induced pluripotent stem cells (iPSCs) possess the potential to differentiate into neural lineage cells. Matrix metalloproteinase 2 (MMP2), an endopeptidase in the extracellular matrix, has been shown to protect neural cells from injury. However, the mechanisms and effects of MMP2 on neural differentiation of iPSCs remain poorly understood. Here, we demonstrated a role for MMP2 in the differentiation of iPSCs to neurons via the AKT pathway. Treatment of iPSCs with MMP2 promoted their proliferation and differentiation into neural stem cells (NSCs), and then into neurons...
