Frog ribonucleases have been demonstrated to have anticancer activities. However, whether RC-6 ribonuclease exerts anticancer activity on human embryonal carcinoma cells remains unclear. In the present study, RC-6 induced cytotoxicity in NT2 cells (a human embryonal carcinoma cell line) and our studies showed that RC-6 can exert anticancer effects and induce caspase-9 and -3 activities. Moreove...

N-TERA-2 cl/D1 (NT2) cells, a human embryonal cell line with characteristics of central nervous system precursor cells, were utilised to study thyroid hormone action during early neuronal growth and differentiation. Undifferentiated NT2 cells expressed mRNAs encoding thyroid hormone receptors (TRs) alpha1, alpha2 and beta1, iodothyronine deiodinases types 2 (D2) and 3 (D3) (which act as the pre...

Abstract Non-sleep symptoms, as depression, anxiety and overweight, are often encountered in narcoleptic patients. The purposes of this study to evaluate mood, impulsiveness, emotion, alexithymia, eating behavior patients with narcolepsy type 1 (NT1) 2 (NT2) compared healthy controls investigate possible correlations between clinical-demographic data, polysomnographic parameters, subjective que...

Background and Objective Several studies have raised questions about determining the diagnosis of narcolepsy using multiple sleep latency test (MSLT). In this study, we investigated diagnostic change in type 1 (NT1) 2 (NT2) MSLT with long-term interval.Methods retrospective demographic characteristics, polysomnography (PSG), parameters were compared at baseline between NT1 NT patients. Then, re...

Induction of differentiation in cancer stem cells by drug treatment represents an important approach for cancer therapy. The understanding of the mechanisms that regulate such a forced exit from malignant pluripotency is fundamental to enhance our knowledge of tumour stability. Certain nucleoside analogues, such as 2'-deoxy-5-azacytidine and 1β-arabinofuranosylcytosine, can induce the different...

A major focus of stem cell research is the generation of neurons that may then be implanted to treat neurodegenerative diseases. However, a picture is emerging where astrocytes are partners to neurons in sustaining and modulating brain function. We therefore investigated the functional properties of NT2 derived astrocytes and neurons using electrophysiological and calcium imaging approaches. NT...

Retinoic acid (RA), a derivative of vitamin A, is essential for normal patterning and neurogenesis during development. Until recently, studies have been focused on the physiological roles of RA receptors (RARs), one of the two types of nuclear receptors, whereas the functions of the other nuclear receptors, retinoid X receptors (RXRs), have not been explored. Accumulating evidence now suggests ...
