We previously developed a refined, tumor-selective adenovirus, Ad5NULL -A20, harboring tropism ablating mutations in each major capsid protein, to ablate all native means of infection. We incorporated a 20-mer peptide (A20) in the fiber knob for selective infection via αvβ6 integrin, a marker of aggressive epithelial cancers. Methods: To ascertain the selectivity of Ad5NULL -A20 for αvβ6-positive tumor cell lines of pancreatic and breast cancer origin, we performed reporter gene and cell viability assays...

It is increasingly clear that an extraordinarily diverse range of clinically important conditions-including infections, vaccinations, autoimmune diseases, transplants, transfusion reactions, aging, and cancers-leave telltale signatures in the millions of V(D)J-rearranged antibody and T cell receptor [TR per the Human Genome Organization (HUGO) nomenclature but more commonly known as TCR] genes collectively expressed by a person's B cells (antibodies) and T cells. We refer to these as the immunome . Because of its diversity and complexity, the immunome provides singular opportunities for advancing personalized medicine by serving as the substrate for a highly multiplexed, near-universal blood test...

AIMS: This study aimed to validate the application of combined multiplex immunofluorescence (mIF) and digital image analysis (DIA) in formalin-fixed and paraffin-embedded tissues for the quantitative assessment of programmed death-ligand 1(PD-L1) and immune cells (ICs) in non-small cell lung cancer (NSCLC). METHODS: Fifty resected samples of NSCLC were sequentially stained with a DNA-tagged mIF (panel including PD-L1, CKpan, CD8, CD68 and 4',6-diamidino-2-phenylindole (DAPI)) and conventional immunohistochemistry (cIHC)...

Acquired estrogen receptor 1 (ESR1) mutation is being promoted as a key mechanism of resistance to endocrine therapies in breast cancers. It is significative to monitor ESR1 mutations in real time, which provide an opportunity to alter therapy as these mutations emerge. Previous assays based on next-generation sequencing (NGS) and digital PCR (dPCR) usually due to high costs and complicated workflows hampered their clinical adoption in general medical institutions. Here, we proposed a new strategy using base-specific invasive reaction assisted qPCR measure for ESR1 mutations in cfDNA...

Genomic instability is a hallmark of cancer, and has a central role in the initiation and development of breast cancer1,2 . The success of poly-ADP ribose polymerase inhibitors in the treatment of breast cancers that are deficient in homologous recombination exemplifies the utility of synthetically lethal genetic interactions in the treatment of breast cancers that are driven by genomic instability3 . Given that defects in homologous recombination are present in only a subset of breast cancers, there is a need to identify additional driver mechanisms for genomic instability and targeted strategies to exploit these defects in the treatment of cancer...

Aberrant activation of the Wnt signalling pathway is required for tumour initiation and survival in the majority of colorectal cancers. The development of inhibitors of Wnt signalling has been the focus of multiple drug discovery programs targeting colorectal cancer and other malignancies associated with aberrant pathway activation. However, progression of new clinical entities targeting the Wnt pathway has been slow. One challenge lies with the limited predictive power of 2D cancer cell lines because they fail to fully recapitulate intratumoural phenotypic heterogeneity...

BACKGROUND: Growing evidence directly suggested that circular RNAs (circRNAs) are crucial contributors in the course of cervical cancer (CC) onset and progression. Nevertheless, a large number of circRNAs have not been fully addressed in their function and underlying mechanisms during CC etiology. PURPOSE: Our study focused on the function of circRNA MYLK (myosin light chain kinase), one novel tumor-related circRNA, in CC cell behaviors. METHODS: Firstly, we evaluated the expression profile of circMYLK in CC cells and in normal Ect1/E6E7 cell line...

BACKGROUND Acori Tatarinowii Rhizoma (ATR), a traditional Chinese herbal medicine, is used to treat Alzheimer's disease (AD), which is a worldwide degenerative brain disease. The aim of this study was to identify the potential mechanism and molecular targets of ATR in AD by using network pharmacology. MATERIAL AND METHODS The potential targets of the active ingredients of ATR were predicted by PharmMapper, and the targets of Alzheimer's disease were searched by DisGeNET. All screened genes were intersected to obtain potential targets for the active ingredients of ATR...

OBJECTIVE: Owing to inconsistency between reports, a meta-analysis was designed to appraise the clinical implications of long non-coding RNAs (lncRNAs) in urine and blood for the diagnosis of bladder cancer. METHODS: Studies that met the criteria were acquired by bibliographic retrieval through PubMed, Embase, and the Cochrane Library. The pooled diagnostic performance was evaluated by calculating the area under the summary receiver operator characteristic (SROC) curve...

Isoliquiritigenin, a flavonoid extracted from licorice root, has been shown to be active against most cancer cells; however, its antitumor activity is limited by its poor water solubility. The aim of this study was to develop a stable isoliquiritigenin nanosuspension for enhanced solubility and to evaluate its in vitro cytostatic activity in A549 cells. The nanosuspension of isoliquiritigenin was prepared through wet media milling with HPC SSL (hydroxypropyl cellulose-SSL) and PVP K30 (polyinylpyrrolidone-K30) as stabilizers, and the samples were then characterized according to particle size, zeta-potential, SEM (scanning electron microscopy), TEM (transmission electron microscopy), DSC (differential scanning calorimetry), XRPD (X-ray powder diffraction), FTIR (Fourier transform infrared spectroscopy), XPS (X-ray photoelectron spectroscopy), and in vitro release...

The function of the fibrinolytic system was first identified to dissolve fibrin to maintain vascular patency. Connections between the fibrinolytic system and many other physiological and pathological processes have been well established. Dysregulation of the fibrinolytic system is closely associated with multiple pathological conditions, including thrombosis, inflammation, cancer progression, and neuropathies. Thus, molecules in the fibrinolytic system are potent therapeutic and diagnostic targets. This review summarizes the currently used agents targeting this system and the development of novel therapeutic strategies in experimental studies...

Serine protease inhibitor Kazal-type 1 (SPINK1) is a trypsin kinase inhibitor, which is involved in the development of inflammation, cell proliferation and cancer development and progression. However, the prognostic value of SPINK1 in non-small cell lung cancer (NSCLC) and its ability to regulate intrinsic redox homeostasis have, to the best of our knowledge, not been previously investigated. In the present study, it was revealed that SPINK1 is highly expressed in NSCLC tissue samples compared with normal tissue samples, and may be a potential prognostic marker of NSCLC...

PURPOSE: To assess the safety and efficacy of transarterial chemoembolization using a 75-μm drug-eluting embolic (DEE) in patients with unresectable hepatocellular carcinoma (HCC). MATERIALS AND METHODS: The medical records of 109 patients with a mean age of 64.1 years (range 85-49) treated for unresectable HCC between November 2013 and August 2016 with transarterial chemoembolization using a 75-μm DEE were retrospectively reviewed. Patients who had prior therapy for HCC were excluded...

PURPOSE: Non-small lung cancer (NSCLC) is one of most common cancers worldwide. microRNAs (miRNAs) play an important role in animal biological processes, such as cell growth, differentiation and apoptosis. The aim of this study was to investigate whether MiR-24 can regulate cell proliferation of NSCLC by targeting ZNF367. METHODS: Real time quantitative PCR (qRT-PCR) was used to detect the expression levels of MiR-24 and ZNF367. Western blot assay was employed to analyze the protein levels...

AIM: Colorectal cancer (CRC) is a common human malignancy which accounts for 600,000 deaths annually at the global level. Soyasapogenol B (Soy B), an ingredient of soybean, has been found to exert anti-proliferative activities in vitro in human breast cancer cells. The current study aimed to evaluate the efficacy of Soy B in suppressing CRC. METHODS AND MATERIALS: The effect of Soy B on cell viability was assessed using the Cell Counting Kit-8 (CCK-8) assay. The effect of Soy B on cell proliferation was determined using colony formation assay...

A negative lymph node (NLN) may represent a stronger predictor for the overall survival (OS) rate of patients with esophageal squamous cell carcinoma (ESCC), when compared with a positive LN (PLN). The present study aimed to investigate which LN station, containing the NLN, was associated with OS rate. A retrospective review was conducted in 216 patients with ESCC and a forward stepwise Cox regression model analysis was used to assess the relationship between clinical parameters and OS rate. Patients were divided into subgroups according to the status of the LN at station 108...

Hepatocellular carcinoma (HCC) is a common cause of cancer-related death, with incidence increasing worldwide. Unfortunately, the overall prognosis for patients with HCC is poor and many patients present with advanced stages of disease that preclude curative therapies. Diagnostic and interventional radiologists play a key role in the management of patients with HCC. Diagnostic radiologists can use contrast-enhanced computed tomography (CT), magnetic resonance imaging, and ultrasound to diagnose and stage HCC, without the need for pathologic confirmation, by following established criteria...

Histone deacetylases (HDACs) are known to be key enzymes in cancer development and progression through their modulation of chromatin structure and the expression and post-translational modification of numerous proteins. Aggressive dedifferentiated tumors, like glioblastoma, frequently overexpress HDACs, while HDAC inhibition can lead to cell cycle arrest, promote cellular differentiation and induce apoptosis. Although multiple HDAC inhibitors, such as quisinostat, are of interest in oncology due to their potent in vitro efficacy, their failure in the clinic as monotherapies against solid tumors has been attributed to poor delivery...

B-cell responses result in clonal expansion, and can occur in a variety of tissues. To define how B-cell clones are distributed in the body, we sequenced 933,427 B-cell clonal lineages and mapped them to eight different anatomic compartments in six human organ donors. We show that large B-cell clones partition into two broad networks-one spans the blood, bone marrow, spleen and lung, while the other is restricted to tissues within the gastrointestinal (GI) tract (jejunum, ileum and colon). Notably, GI tract clones display extensive sharing of sequence variants among different portions of the tract and have higher frequencies of somatic hypermutation, suggesting extensive and serial rounds of clonal expansion and selection...
