Computational simulations and models enable development of NMs with optimal characteristics and provide a deeper knowledge of NM interaction with biosystems. This review highlights the biomedical significance of the multifunctional NMs particularly those applied for the development of 2-D or 3-D BMs for a variety of applications including the site-specific delivery of therapeutics. The powerful impacts of the computational techniques on the design process of NMs, quantitation and prediction of protein corona formation, risk assessment, and individualized therapy for improved therapeutic outcomes have also been discussed.
The aim of the study was to investigate the interaction between cannabinoid CB
/CB
and lysophosphatidic acid (LPA) receptors in controlling neuronal signaling and fate.

HT22 hippocampal cells were treated with different cannabinoid and LPA receptor agonists and antagonists. Western blot and immunofluorescence microscopy were used to study intracellular signaling and the expression of apoptotic markers. Cell viability was determined by a luminescence assay.

Cannabinoid agonists induced activation of both ERK1/2 and p38 MAP kinases. The effects of the CB
/CB
receptor agonist HU210 were antagonized by the CB
antagonist rimonabant, whereas the responses to the CB
agonist JWH133 were blocked by the CB
antagonist SR144528. HU210 reduced the apoptotic cell death induced by the pro-inflammatory cytokine TNF-α, whereas JWH133 enhanced the cytokine cytotoxicity. Blockade of ERK1/2 and p38 MAPK activation abrogated the HU210 pro-survival and the JWH133 pro-apoptotic effects, respectively. HU210 and theated ERK1/2 signaling and neuroprotection.
Adenoid hypertrophy (AH) can cause harmful effects on untreated children, which include mouth breathing, chronic intermittent hypoxia, sleep disordered breathing (SDB), and even some behavioral problems. However, the molecular mechanisms underlying this pathophysiological process have remained poorly understood.

In this study, SUMO was induced silencing and overexpression using RNAi and lentiviral-mediated vector. FITC-Dextran and TEER were performed to examine the role of SUMO in cell permeability. Co-immunoprecipitation (Co-IP) assay was performed to examine the interaction between SUMO1 and HIF-1α. Immunohistochemistry staining was used to examine the expressions of ZO-1, Claudin-1 and occluding respectively.

We found that a hypoxic condition caused a dramatic upregulation of SUMO-1 expression in a time-dependent manner, a member of the ubiquitin-like protein family. Knockdown of SUMO-1 deeply suppressed the secretions of pro-inflammation cytokines including IL-6, IL-8, and TNF-α, and decreased the permeability of HTECs. Moreover, the HIF-1α inhibitor 2-MeOE2 abolished the function of SUMO-1 in HTECs. Furthermore, results obtained from CO-IP had suggested that SUMO-1 interacted with HIF-1α, and prevented its ubiquitination and degradation in HTECs by sumoylating. Importantly, our data showed that hypoxia-induced inflammation was markedly inhibited by M2 macrophages that possess potent anti-inflammatory function.

Our results suggest that selectively inhibiting the SUMO-1-HIF-1α signaling pathway leads to anti-inflammatory responses in human tonsil epithelial cells, which might be a novel therapeutic approach for managing hypoxia-induced SDB resulting from AH.

Currently, the main problems with chemotherapy are its side effects, toxicity, and drug resistance. Selleck Tofacitinib Propolis has biological activities, such as anti-inflammatory and anti-cancer properties. This study aims to examine the combined effects of 5-fluorouracil (5FU) and propolis on colorectal cancer (CRC) in mouse models.

The chemical composition of ethanolic extract of propolis was determined by gas chromatography-mass spectrometry (GC-MS). In this study, 49 male Balb/c mice (16-20g) were divided in seven groups as a control group and experimental groups (treated and untreated CRC model [azoxymethane+dextran sodium sulfate]). This study was conducted in 8weeks. To examine the anti-cancer effects of propolis, the number of aberrant crypt foci (ACF) was counted and the pathological lesions in the distal colonic epithelial tissue were diagnosed. In this study, the expression of beta-catenin (β-catenin), induced nitric oxide synthase (iNOS) and cyclooxygenase-2 (Cox-2) proteins, which play a major role in the incidence and progression of cancer, were determined.

GC-MS analysis of propolis showed the presence of hydrocarbons, alcohols, ketones, terpenes, phenols, and flavonoids. Administering propolis in combination with 5FU reduced the number of ACFs and pathological lesions in comparison with cancer control groups (p<0.0001) and 5FU-alone treatment (p<0.05). The propolis combined with 5FU reduced the expression of Cox-2, iNOS, and β-catenin proteins.

The results showed that propolis increased the efficiency of 5FU and could be taken into account as the adjunct therapy for colorectal cancer.

Dysregulated microRNA-145-5p (miR-145-5p) contributes to hepatic fibrosis (HF) while extracellular vesicles have the therapeutic capacities to treat this disease. Based on that, this work is initiated from human umbilical cord blood mesenchymal stem cells (HUCB-MSCs)-derived exosomes delivering miR-145-5p to regulate fascin actin-bundling protein 1 (FSCN1) for attenuating HF.

A rat model of HF was established using carbon tetrachloride (CCl4) intraperitoneal injection. CCl4 model rats were given administration of HUCB-MSCs-derived exosomes or modified exosomes with up-regulated or down-regulated miR-145-5p. The resulting pathological changes, liver function, collagen deposition and fibrosis-related factors α-smooth muscle actin (α-SMA) and collagen I expression, inflammatory cytokines, hepatocyte apoptosis and apoptosis-related factors (caspase-3, Bax and Bcl-2) expression were analyzed. miR-145-5p and FSCN1 expression, along with their internal action were tested.

Depressed miR-145-5p and overexpressed FSCN1 existed in HF.
