RON (Recepteur d'Origine Nantais) tyrosine kinase receptor is a promising target for therapeutic intervention in cancer therapy. The aim of this work was identification of RON-binding peptides using phage display and computational modeling their mode of binding. A 12-mer peptide phage library was utilized to perform biopanning against RON. The RON-binding ability of the selected peptide-displaying phage and their possible binding sites were examined by ELISA. Binding modes and affinities were also predicted by docking and molecular dynamics (MD) simulation...

Cardiac resynchronization therapy is not effective in a variable proportion of heart failure patients. An accurate knowledge of each patient's electroanatomical features could be helpful to determine the most appropriate treatment. The goal of this study was to analyze and quantify the sensitivity of left ventricular (LV) activation and the electrocardiogram (ECG) to changes in 39 parameters used to tune realistic anatomical-electrophysiological models of the heart. Electrical activity in the ventricles was simulated using a reaction-diffusion equation...

BACKGROUND: Vascularized composite allotransplantation (VCA) is a rapidly expanding field of transplantation and provides a potential treatment for complex tissue defects. Peripheral blood mononuclear cells (PBMCs) shortly incubated with the antibiotic and chemotherapeutic agent mitomycin C (MMC) can suppress allogeneic T cell response and control allograft rejection in various organ transplantation models. MMC-incubated PBMCs (MICs) are currently being tested in a phase I clinical trial in kidney transplant patients...

Glioblastoma, also known as glioblastoma multiforme (GBM), is the most recurrent and malignant astrocytic glioma found in adults. Biologically, GBMs are highly aggressive tumors that often show diffuse infiltration of the brain parenchyma, making complete surgical resection difficult. GBM is not curable with surgery alone because tumor cells typically invade the surrounding brain, rendering complete resection unsafe. Consequently, present-day therapy for malignant glioma remains a great challenge. The location of the invasive tumor cells presents several barriers to therapeutic delivery...

Pancreatic cancer is one of the most lethal and aggressive cancers in the world. However, no effective treatment is currently available for pancreatic cancer. The objective of this study was to determine the anti-pancreatic cancer effect of α-mangostin (αM) and γ-mangostin (γM) extracted from the pericarp of Garcinia mangostana L.. Both αM and γM reduced the viability of pancreatic cancer cells MIA PaCa-2 and PANC-1 in a dose-dependent manner. These compounds induced apoptosis by increasing c-PARP and c-Caspase 3 levels...

Failure of the right ventricle (RV) is a serious disease with a poor prognosis and limited treatment options. Signaling by α1-adrenergic receptors (α1-ARs), in particular the α1A-subtype, mediate cardioprotective effects in multiple heart failure models. Recent studies show that chronic treatment with the α1A-subtype agonist A61603 improves function and survival in a model of LV failure. The goal of this study was to determine if chronic A61603 treatment is beneficial in a RV failure model. We used tracheal instillation of the fibrogenic antibiotic bleomycin in mice to induce pulmonary fibrosis, pulmonary hypertension, and RV failure within 2 wk...

Accumulating evidence suggest that patients with advanced non-small-cell lung cancer (NSCLC) and specific genomic alterations including epidermal growth factor receptor and microtubule-associated protein-like 4 anaplastic lymphoma kinase could significantly benefit from molecular-targeted therapies compared with chemotherapy. Recently, immunotherapy based on programmed cell death 1 (PD-1) and its ligand (PD-L1) blockade prolong survival in patients with advanced NSCLC, especially in those patients with positive expression of PD-L1 and when used in the first-line setting...

Fast dissolving nanofiber (NF) composed of poly(vinyl alcohol) (PVA) and d-α-tocopheryl polyethylene glycol succinate (TPGS) was developed for locoregional delivery of phloretin to oral cancers. PVA/TPGS/phloretin NF with 321nm mean diameter and >90% drug entrapment efficiency was fabricated by an electrospinning method. Transformation of drug from crystalline to amorphous state was identified by solid-state studies. NF structure was changed to nanoparticles after its dispersing in the aqueous medium. PVA/TPGS/phloretin NF exhibited fast wetting property and smaller hydrodynamic size of dispersion, compared with PVA/phloretin NF...

The cyclic 3',5'-adenosine monophosphate (cAMP) was the first among the so-called "second messengers" to be described. It is conserved in most organisms and functions as a signal transducer by mediating the intracellular effects of multiple hormones and neurotransmitters. In this review, we first delineate how different members of the cAMP pathway ensure its correct compartmentalization and activity, mediate the terminal intracellular effects, and allow the crosstalk with other signaling pathways. We then focus on the pituitary gland, where cAMP exerts a crucial function by controlling the responsiveness of the cells to hypothalamic hormones, neurotransmitters and peripheral factors...

Noninvasive biological readouts of tumor metastatic risk and therapeutic efficacy are needed as healthcare costs rise. Conventional imaging modalities are expensive; require significant periods of time to see appreciable change and repetitive use increases risk of hazardous side effects. Utilizing circulating tumor cells (CTCs) as a minimally invasive biological readout of tumor progression or therapeutic response is increasingly being studied. While focus has primarily been on the predictive value of naturally occurring CTCs, a more recent effort has emerged regarding the potential consequence of therapy induced CTCs...

Novel antineoplastic therapies are focused on harnessing our own immune system to fight cancer. To that end, cytotoxic T-lymphocyte-associated antigen 4 and programmed death ligand 1 are 2 coinhibitory signals that play central roles in decreasing T-cell response and represent a class of medications termed "checkpoint inhibitors." We present an unusual case of progressive conduction abnormalities induced by checkpoint inhibitors. Prompt medical intervention resulted in full recovery. Despite the anticancer efficacy, the newer antineoplastic agents pose a significant and often life-threatening risk of cardiotoxicity...

Three-dimensional (3D) brain organoids derived from human pluripotent stem cells (hPSCs), including embryonic stem cells (ESCs) and induced pluripotent stem cells (iPSCs), appear to recapitulate the brain's 3D cytoarchitectural arrangement and provide new opportunities to explore disease pathogenesis in the human brain. Human iPSC (hiPSC) reprogramming methods, combined with 3D brain organoid tools, may allow patient-derived organoids to serve as a preclinical platform to bridge the translational gap between animal models and human clinical trials...

Serum urate levels are reported to be significantly lowered in patients with Parkinson's disease (PD) and inversely correlated to the risk and progression of PD. However, the mechanism by which urate affects PD is poorly understood. Here we showed that treatment with uric acid (UA) resulted in an autophagy activity enhancement in PC12 cells in dose- and time-dependent manners, as indicated by LC3-II increase and P62 decrease. Moreover, UA was still able to increase the LC3-II level and the number of LC3 puncta in the presence of Bafilomycin A1, a lysosomal inhibitor...

In this review, mucosal immune defense mechanisms used to control infections in the bovine genital tract (vestibule, vagina, cervix, uterus and oviduct) during the postpartum period are reviewed. Knowledge gaps are highlighted to emphasize the need for further investigations. Physical barriers to the entry of microbes include vulvar sealing, vestibule-vaginal constriction, a narrow cervical opening and the mucosal epithelium along with the overlying mucus layer. Genital tract mucosal epithelial cells recognize damage-associated molecular patterns and pathogen-associated molecular patterns and respond by secreting antimicrobial peptides and cytokines to recruit and activate immune cells...
