Summary We aimed to assess the expression and distribution of Hsp27, pHsp27 (Ser82), p38MAPK and p-p38MAPK in fibro-fatty atherosclerotic lesions and the myocardium of hypercholesterolaemic rabbits. Male New Zealand white rabbits were fed a high-cholesterol diet for 18 weeks, maintaining serum cholesterol at approximately 20 mmol/l over this period. Aortic arch and myocardial tissues were analysed by Western blot, immunohistochemistry and double immunofluorescence. Plasma Hsp27 levels were measured by ELISA. There was a significant increase in the expression of monomeric and dimeri... περισσότερα »

Prenatal exposure to ethinylestradiol alters the morphologic patterns and increases the predisposition for prostatic lesions in male and female gerbils during ageing

Alexandros G. SfakianakisστοCell and Tissue Research by Alexandros G. SfakianakisΠριν από 1 λεπτό
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 »

Sleep Apnea Treatment- The Canadian Experience: So, you’re tired of feeling tired or hearing from your spouse about your snoring. You go to your family physician, which refers you to a Sleep Specialist. After the Sleep Study results are available you are told that you stop breathing in your sleep 30 times an hour, something that would concern most people. You are then told about lifestyle modifications that you may want to consider, and various therapeutic approaches. But the one they highly recommend, and that the government sponsored Health Plan covers is CPAP. Continuous Positiv... περισσότερα »

Cav 1.3 (CACNA1D) L-type Ca(2+) channel dysfunction in CNS disorders.

Alexandros G. SfakianakisστοOtoRhinoLaryngology - Alexandros G. SfakianakisΠριν από 8 δευτερόλεπτα
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 »

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 […]

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 […]

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 […]

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 […]

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, […]

Characterization of EZH2 Inhibitors in Multiple Myeloma

Alexandros G. SfakianakisστοΟγκολογίαΠριν από 1 ώρα
Multiple myeloma is a plasma cell malignancy characterized by marked heterogeneous genomic instability including frequent genetic alterations in epigenetic enzymes. 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

Alexandros G. SfakianakisστοΟγκολογίαΠριν από 1 ώρα
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 »

Synthetic Lethality between CDK and PARP Inhibition

Alexandros G. SfakianakisστοΟγκολογίαΠριν από 1 ώρα
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 »

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 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 »
