Characterization of an AAC-11-derived anticancer peptide

Alexandros G. SfakianakisστοΑισθητική ΔερματολογίαΠριν από 9 δευτερόλεπτα
AAC-11 is an anti-apoptotic protein that is upregulated in most cancer cells. Increased expression of AAC-11 confers a survival advantage when cancer cells are challenged with various stresses and contributes to tumor invasion and metastases whereas its deregulation reduces resistance to chemotherapeutic drugs. The antiapoptotic effect of AAC-11 may be clinically relevant as its expression correlates with poor prognosis in several human cancers. Thus, inactivation of AAC-11 might constitute an attractive approach for developing cancer therapeutics. We have developed an AAC-11-deri... περισσότερα »

Clathrin regulates lymphocyte migration by driving actin accumulation at the cellular leading edge

Alexandros G. SfakianakisστοAllergy Rhinology Immunology AsthmaΠριν από 13 δευτερόλεπτα
[image: cover.gif?v=1&s=a7ea901f55e135f2a892ad12] Lymphocyte migration, which is essential for effective immune responses, belongs to the so-called amoeboid migration. The lymphocyte migration is up to 100 times faster than between mesenchymal and epithelial cell types. Migrating lymphocytes are highly polarized in three well-defined structural and functional zones: uropod, medial zone and leading edge. The actiomyosin-dependent driving force moves forward the uropod, whereas massive actin rearrangements protruding the cell membrane are observed at the leading edge. These actin re... περισσότερα »

BOIN: A Simple, Well-Performing Bayesian Phase I Design

Alexandros G. SfakianakisστοSquamous cell carcinoma (SCC) - Cancer - MelanomaΠριν από 25 δευτερόλεπτα
Despite more than two decades of publications that offer more innovative model-based designs, the classical 3+3 design remains the most dominant phase I trial design in practice. In this article, we introduce a new trial design, the Bayesian optimal interval (BOIN) design. The BOIN design is easy to implement in a way similar to the 3+3 design, but is more flexible for choosing the target toxicity rate and cohort size and yields a substantially better performance that is comparable to that of more complex model-based designs. The BOIN design contains the 3+3 design and the acceler... περισσότερα »

miR-644a Functions as Tumor Suppressor in ESCC

Alexandros G. SfakianakisστοSquamous cell carcinoma (SCC) - Cancer - MelanomaΠριν από 27 δευτερόλεπτα
Purpose: We previously reported the oncogenic role of paired-like homeodomain 2 (PITX2) in esophageal squamous cell carcinoma (ESCC). In this study, we aimed to identify the microRNA (miRNA) regulators of PITX2 and the mechanism underlying the pathogensis of ESCC. Experimental Design: Using miRNA profiling and bioinformatics analyses, we identified miR-644a as a negative mediator of PITX2 in ESCC. A series of in vivo and in vitro assays were performed to confirm the effect of miR-644a on PITX2-mediated ESCC malignancy. Results: ESCC cells and tissues expressed less miR-644a than n... περισσότερα »

“I Don’t Need Help”: Gender Differences in how Gender Stereotypes Predict Help-Seeking

Alexandros G. SfakianakisστοΙατρικά Άρθρα by Alexandros G. SfakianakisΠριν από 32 δευτερόλεπτα
Abstract Although self-report and correlational studies suggest that gender stereotypes are related to men's health behavior, particularly in relation to seeking help, there is minimal research that has tested this hypothesis experimentally. The present study examined how two stereotype pathways, personally endorsed gender stereotypes and gender stereotyped attitudes, predicted help-seeking behavior among U.S. undergraduate women (*n* = 68) and men (*n* = 72) when they worked on challenging puzzles and recalled previous health help-seeking behavior for physical or psychological pr... περισσότερα »

With increased involvement of genetic data in most epidemiological investigations, gene–environment (G x E) interactions now stand as a topic, which must be meticulously assessed and thoroughly understood. The level, mode, and outcomes of interactions between environmental factors and genetic traits have the capacity to modulate disease risk. These must, therefore, be carefully evaluated as they have the potential to offer novel insights on the "missing heritability problem", reaching beyond our current limitations. First, we review a definition of G x E interactions. We then expl... περισσότερα »

Inhibition of Information Flow to the Default Mode Network During Self-Reference Versus Reference to Others

Alexandros G. SfakianakisστοΝευρολογία κ' ΝευροχειρουργικήΠριν από 1 ώρα
The default mode network (DMN), a network centered around the cortical midline, shows deactivation during most cognitive tasks and pronounced resting-state connectivity, but is actively engaged in self-reference and social cognition.

Physiological modulators of Kv3.1 channels adjust firing patterns of auditory brain stem neurons

Alexandros G. SfakianakisστοPhysiology by Alexandros G.SfakianakisΠριν από 1 ώρα
Many rapidly firing neurons, including those in the medial nucleus of the trapezoid body (MNTB) in the auditory brain stem, express "high threshold" voltage-gated Kv3.1 potassium channels that activate only at positive potentials and are required for stimuli to generate rapid trains of actions potentials. We now describe the actions of two imidazolidinedione derivatives, AUT1 and AUT2, which modulate Kv3.1 channels. Using Chinese hamster ovary cells stably expressing rat Kv3.1 channels, we found that lower concentrations of these compounds shift the voltage of activation of Kv3.1 ... περισσότερα »
