Prenatal exposure to ethinylestradiol alters the morphologic patterns and increases the predisposition for prostatic lesions in male and female gerbils during ageing
Summary Ethinylestradiol (EE) is an endocrine disruptor (ED) which acts as an oestrogen agonist; this compound is known as an oral contraceptive. Male and female rodents exposed to EE during critical time points of development, such as in the prenatal period, show alterations in their reproductive tract during adulthood. Few studies have placed an emphasis on the effects of EE during ageing. Thus, this study had as it's objective the analysis of the morphological and immunohistochemical effects of exposure to EE in the prenatal period on ventral male prostate and female prostate o...περισσότερα »

Cav 1.3 (CACNA1D) L-type Ca(2+) channel dysfunction in CNS disorders.
Cav 1.3 (CACNA1D) L-type Ca(2+) channel dysfunction in CNS disorders Authors: Pinggera A, Striessnig J Abstract Cav 1.3 belongs to the family of voltage-gated L-type Ca(2+) channels and is encoded by the CACNA1D gene. Cav 1.3 channels are not only essential for cardiac pacemaking, hearing and hormone secretion but are also expressed postsynaptically in neurons, where they shape neuronal firing and plasticity. Recent findings provide evidence that human mutations in the CACNA1D gene can confer risk for the development of neuropsychiatric disease and perhaps also epilepsy. Loss of Ca...περισσότερα »

PARP1/2 are required for single-strand break repair, and their inhibition causes DNA replication fork collapse and double-strand break (DSB) formation. These DSBs are primarily repaired via homologous recombination (HR), a high-fidelity repair pathway. Should HR be deficient, DSBs may be repaired via error-prone nonhomologous end-joining mechanisms, or may persist, ultimately resulting in cell death. The […]

In particular, the histone methyltransferase Enhancer of Zeste Homolog 2 (EZH2) is overexpressed in multiple myeloma. EZH2 is the catalytic component of the polycomb repressive complex 2 (PRC2), a master transcriptional regulator of differentiation. EZH2 catalyzes methylation of lysine 27 on histone H3 and its deregulation in cancer has been reported to contribute to silencing of tumor suppressor genes, resulting in a m...περισσότερα »
In Vivo Delivery of Orlistat as Cancer Therapeutic
Triple-negative breast cancer (TNBC) is a recalcitrant malignancy with no available targeted therapy. Off-target effects and poor bioavailability of the FDA-approved antiobesity drug orlistat hinder its clinical translation as a repurposed new drug against TNBC. Here, we demonstrate a newly engineered drug formulation for packaging orlistat tailored to TNBC treatment. We synthesized TNBC-specific folate receptor–targeted micellar nanoparticles (NP) carrying orlistat, which improved the solubility (70–80 μg/mL) of this water-insoluble drug. The targeted NPs also improved the delive... περισσότερα »
ABPP Identifies TBK1 for Small Cell Lung Cancer Therapy
To overcome hurdles in identifying key kinases in small cell lung cancer (SCLC), we integrated a target-agnostic phenotypic screen of kinase inhibitors with target identification using activity-based protein profiling (ABPP) in which a desthiobiotin-ATP probe was used. We screened 21 SCLC cell lines with known c-MYC amplification status for alterations in viability using a chemical library of 235 small-molecule kinase inhibitors. One screen hit compound was interrogated with ABPP, and, through this approach, we reidentified Aurora kinase B as a critical kinase in MYC-amplified SCL... περισσότερα »
Optimization of RGD-Containing Peptides
We have previously reported the use of one-bead-one-compound (OBOC) combinatorial technology to develop a disulfide cyclic, Arg-Gly-Asp–containing octapeptide LXW7 (cGRGDdvc), that targets αvβ3 integrin with high affinity and specificity. αvβ3 integrin is known to be overexpressed in many cancers and in tumor vasculature, and it has been established as a cancer therapeutic target. To further optimize LXW7, we have performed systematic structure–activity relationship studies. On the basis of the results, two highly focused OBOC peptide libraries were designed, synthesized, and scre...περισσότερα »
The HLA/MIF Complex as a Surface Target for Ovarian Cancer
T cells recognize cancer cells via HLA/peptide complexes, and when disease overtakes these immune mechanisms, immunotherapy can exogenously target these same HLA/peptide surface markers. We previously identified an HLA-A2–presented peptide derived from macrophage migration inhibitory factor (MIF) and generated antibody RL21A against this HLA-A2/MIF complex. The objective of the current study was to assess the potential for targeting the HLA-A2/MIF complex in ovarian cancer. First, MIF peptide FLSELTQQL was eluted from the HLA-A2 of the human cancerous ovarian cell lines SKOV3, A27... περισσότερα »
Synthetic Lethality between CDK and PARP Inhibition
PARP1/2 are required for single-strand break repair, and their inhibition causes DNA replication fork collapse and double-strand break (DSB) formation. These DSBs are primarily repaired via homologous recombination (HR), a high-fidelity repair pathway. Should HR be deficient, DSBs may be repaired via error-prone nonhomologous end-joining mechanisms, or may persist, ultimately resulting in cell death. The combined disruption of PARP and HR activities thus produces synthetic lethality. Multiple myeloma cells are characterized by chromosomal instability and pervasive DNA damage, impl...περισσότερα »

GC1118, with a Distinct EGFR-Binding Epitope and Efficacy
The EGFR-targeted monoclonal antibodies are a valid therapeutic strategy for patients with metastatic colorectal cancer (mCRC). However, only a small subset of mCRC patients has therapeutic benefits and there are high demands for EGFR therapeutics with a broader patient pool and more potent efficacy. In this study, we report GC1118 exhibiting a different character in terms of binding epitope, affinity, mode of action, and efficacy from other anti-EGFR antibodies. Structural analysis of the EGFR–GC1118 crystal complex revealed that GC1118 recognizes linear, discrete N-terminal epit...περισσότερα »
Inhibition of Class I HDACs in Urothelial Carcinoma
Class I histone deacetylases HDAC1 and HDAC2 contribute to cell proliferation and are commonly upregulated in urothelial carcinoma. To evaluate whether specific inhibition of these enzymes might serve as an appropriate therapy for urothelial carcinoma, siRNA-mediated knockdown and specific pharmacologic inhibition of HDAC1 and HDAC2 were applied in urothelial carcinoma cell lines (UCC) with distinct HDAC1 and HDAC2 expression profiles. HDACs and response marker proteins were followed by Western blotting and qRT-PCR. Effects of class I HDAC suppression on UCCs were analyzed by viab... περισσότερα »
Inhibition of Endothelial AKT and ERK by 2-DG
Interference with endothelial cell metabolism is a promising, yet unexploited strategy for angiogenesis inhibition. We reported that the glucose analogue 2-deoxy-D-glucose (2-DG) inhibits angiogenesis at significantly lower concentrations than those required for tumor cytotoxicity. Here, we found that hypersensitivity to 2-DG in endothelial cells is not associated with enhanced drug uptake compared with tumor cells, but with time-dependent, endothelial-selective inhibition of AKT and ERK phosphorylation. Downregulation of these critical survival pathways is shown to be due to 2-DG... περισσότερα »
Choline Kinase in Pancreatic Ductal Adenocarcinoma
Choline kinase α (CHKα) plays a crucial role in the regulation of membrane phospholipid synthesis and has oncogenic properties *in vitro*. We have analyzed the expression of CHKα in cell lines derived from pancreatic ductal adenocarcinoma (PDAC) and have found increased CHKα expression, associated with differentiation. CHKα protein expression was directly correlated with sensitivity to MN58b, a CHKα inhibitor that reduced cell growth through the induction of apoptosis. Accordingly, CHKα knockdown led to reduced drug sensitivity. In addition, we found that gemcitabine-resistant PDA...περισσότερα »
Nuclear RON in NHEJ DNA Repair
Tumor hypoxia is associated with radioresistance, chemoresistance, and metastasis, which eventually lead to cancer progression and a poor patient prognosis. RON [also known as macrophage-stimulating protein receptor (MST1R)] belongs to the c-MET [also known as hepatocyte growth factor receptor (HGFR)] receptor tyrosine kinase (RTK) superfamily. To identify the interaction partners of RON nuclear translocation in response to hypoxia, the nuclear extract of TSGH8301 bladder cancer cells was immunoprecipitated for tandem mass profiling analysis. Nuclear RON interacted with adenosine ...περισσότερα »

ABT-414, an Antibody Drug Conjugate Targeting a Tumor-Selective EGFR Epitope
Targeting tumor overexpressed epidermal growth factor receptor with an antibody drug conjugate is an attractive therapeutic strategy; however, normal tissue expression represents a significant toxicity risk. The anti-EGFR antibody ABT-806 targets a unique tumor-specific epitope and exhibits minimal reactivity to EGFR in normal tissue suggesting its suitability for the development of an ADC. We describe the binding properties and preclinical activity of ABT-414, an ABT-806 monomethyl auristatin F conjugate. In vitro, ABT-414 selectively kills tumor cells overexpressing wild-type or... περισσότερα »
Targeting Interleukin-11 Receptor-{alpha} Impairs Human Endometrial Cancer Cell Proliferation and Invasion in vitro and Reduces Tumour Growth and Metastasis in vivo.
Endometrial cancer contributes to significant morbidity and mortality in women with advanced stage or recurrent disease. Interleukin (IL)11 is a cytokine that regulates cell cycle, invasion and migration, all hallmarks of cancer. IL11 is elevated in endometrial tumours and uterine lavage fluid in women with endometrial cancer, alters endometrial epithelial cancer cell adhesion and migration in vitro but its role in endometrial tumourigenesis in vivo is unknown. We injected mice subcutaneously with human-derived Ishikawa or HEC1A endometrial epithelial cancer cells (ectopic), or HEC... περισσότερα »

Effective concentration of a multi-kinase inhibitor within bone marrow correlates with in vitro cell killing in therapy-resistant chronic myeloid leukemia
Leukemia cells escape BCR-ABL-targeted therapy by developing mutations such as T315I in the p210BCR-ABL fusion protein in Philadelphia chromosome-positive chronic myeloid leukemia (CML). While most effort has been focused on development of new tyrosine kinase inhibitors (TKIs), enrichment of these small molecule inhibitors in the tumor tissue can also have a profound impact on treatment outcomes. Here, we report that a 2-hour exposure of the T315I mutant CML cells to 10 μM of the multi-kinase inhibitor TG101209 suppressed BCR-ABL-independent signaling and caused cell cycle arrest ...περισσότερα »
Intermittent high dose scheduling of AZD8835, a novel selective inhibitor of PI3K{alpha} and PI3K{delta}, demonstrates treatment strategies for PIK3CA-dependent breast cancers
The PIK3CA gene, encoding the p110α catalytic unit of PI3Kα is one of the most frequently mutated oncogenes in human cancer. Hence PI3Kα is a target subject to intensive efforts in identifying inhibitors and evaluating their therapeutic potential. Here we report studies with a novel PI3K inhibitor, AZD8835, currently in Phase I clinical evaluation. AZD8835 is a potent inhibitor of PI3Kα and PI3K with selectivity vs. PI3Kβ, PI3K and other kinases that preferentially inhibited growth in cells with mutant PIK3CA status, such as in ER+ breast cancer cell lines BT474, MCF7 and T47D (su... περισσότερα »
Antagonizing the Hedgehog Pathway with Vismodegib Impairs Malignant Pleural Mesothelioma Growth In Vivo by Affecting Stroma
An autocrine driven upregulation of the Hedgehog (Hh) signaling pathway has been described in malignant pleural mesothelioma (MPM), in which the ligand, desert hedgehog (DHH), was produced from tumor cells. However, our investigation revealed that the Hh pathway is activated in both tumor and stroma of MPM tumor specimens and an orthotopic immunocompetent rat MPM model. This was demonstrated by positive immunohistochemical staining of Glioma associated oncogene 1 (GLI1) and Patched1 (PTCH1) in both tumor and stromal fractions. DHH was predominantly expressed in the tumor fractions.... περισσότερα »
Combined Effects of Suberoylanilide Hydroxamic Acid and Cisplatin on Radiation Sensitivity and Cancer Cell Invasion in Non-small-cell Lung Cancer
Lung cancer is a leading cause of cancer mortality worldwide, and concurrent chemoradiotherapy has been explored as a therapeutic option. However, the chemotherapeutic agents cannot be administered for most patients at full doses safely with radical doses of thoracic radiation, and further optimizations of chemotherapy regimen to be given with radiation are needed. In this study, we examined the effects of suberoylanilide hydroxamic acid (SAHA) and cisplatin on DNA damage repairs, and determined the combination effects of SAHA and cisplatin on human non-small-cell lung cancer (NSC... περισσότερα »
Trastuzumab-based photoimmunotherapy integrated with viral HER2 transduction inhibits peritoneally disseminated HER2-negative cancer
Peritoneal dissemination is the most frequent metastasis in gastric cancer and is associated with poor prognosis. The lack of particular target antigens in gastric cancer other than human epidermal growth factor receptor 2 (HER2) has hampered the development of treatments for peritoneal dissemination of gastric cancer. We hypothesized that HER2-extracellular domain (HER2-ECD) gene transduction combined with trastuzumab-based photoimmunotherapy (PIT) might provide excellent and selective anti-tumor effects for peritoneal dissemination of gastric cancer.

Clinically relevant variants identified in thoracic aortic aneurysm patients by research exome sequencing
Thoracic aortic aneurysm (TAA) is a genetically heterogeneous disease involving subclinical and progressive dilation of the thoracic aorta, which can lead to life-threatening complications such as dissection or rupture. Genetic testing is important for risk stratification and identification of at risk family members, and clinically available genetic testing panels have been expanding rapidly. However, when past testing results are normal, there is little evidence to guide decision-making about the indications and timing to pursue additional clinical genetic testing. Results from r... περισσότερα »
Two cases of Vici syndrome associated with Idiopathic Thrombocytopenic Purpura (ITP) with a review of the literature
Vici syndrome is a rare congenital disorder first described in 1988. To date, 31 cases have been reported in the literature. The characteristic features of this syndrome include: agenesis of the corpus callosum, albinism, cardiomyopathy, variable immunodeficiency, cataracts, and myopathy. We report two Hispanic sisters with genetically confirmed Vici syndrome who both developed Idiopathic Thrombocytopenic Purpura. To our knowledge, this is an immunologic process that has been previously undescribed within the phenotype of Vici syndrome and should be added to the spectrum of varia... περισσότερα »
