Cytokine expression profiles in children and adolescents with tic disorders.

The etiology of tic disorders (TDs) is not precisely known, although several lines of evidence suggest involvement of the immune system in pathogenesis. Here, we aimed to determine the expression levels of pro-inflammatory and anti-inflammatory cytokines in children with TD and compare them with those of healthy controls. Furthermore, we also evaluated their association with clinical variables in the TD group.

Metastatic progression of breast cancer along with decreased mitochondrial cell death priming of breast cancer cells: a case report.

Metastatic breast cancer remains to be a major cause of cancer-related deaths in women. Exploring the molecular mechanisms to identify targetable alterations in progressing breast cancer and developing functional tools to predict therapy response in these patients are needed. In this report, we present a case of breast cancer patient who progressed following surgery and adjuvant endocrine therapy.

The mechanism of anticancer effects of some pyrrolopyrimidine derivatives on HT-29 human colon cancer cells.

In the present work, the mechanism of anticancer activity of some pyrrolopyrimidine derivatives was evaluated. Compounds 5 and 8 exhibiting significant antiproliferative activity against HT-29 cells with IC values of 4.17 μM and 2.

CYP450 2D6 and 2C19 genotypes in ADHD: not related with treatment resistance but with over-representation of 2C19 ultra-metabolizers.

Objectives: Cytochrome P450 (CYP450) is a major enzyme system involved in drug metabolism as well as regulation of brain function. Although individual variability in CYP enzymes have been studied in terms of personality traits and treatment effects, no study up to now evaluated CYP polymorphisms in children with attention deficit/hyperactivity disorder (ADHD). We aimed to define the genetic profiles of CYP2D6 and CYP2C19 relevant alleles in children with ADHD according to treatment status and compare the frequencies according to past results.

Mitochondrial estrogen receptors alter mitochondrial priming and response to endocrine therapy in breast cancer cells.

Breast cancer is the most common cancer with a high rate of mortality and morbidity among women worldwide. Estrogen receptor status is an important prognostic factor and endocrine therapy is the choice of first-line treatment in ER-positive breast cancer. However, most tumors develop resistance to endocrine therapy.

Kinome-wide RNAi screening for mediators of ABT-199 resistance in breast cancer cells identifies Wee1 as a novel therapeutic target.

Antiapoptotic and proapoptotic BCL-2 protein family members regulate mitochondrial apoptotic pathway. Small molecule inhibitors of antiapoptotic BCL-2 proteins including BCL-2-specific inhibitor ABT-199 (Venetoclax) are in clinical development. However, the efficiency of ABT-199 as a single agent in solid tumors is limited.

RAB25 confers resistance to chemotherapy by altering mitochondrial apoptosis signaling in ovarian cancer cells.

Ovarian cancer remains one of the most frequent causes of cancer-related death in women. Many patients with ovarian cancer suffer from de novo or acquired resistance to chemotherapy. Here, we report that RAB25 suppresses chemotherapy-induced mitochondrial apoptosis signaling in ovarian cancer cell lines and primary ovarian cancer cells.

Novel pyrrolopyrimidine derivatives induce p53-independent apoptosis via the mitochondrial pathway in colon cancer cells.

A series of novel pyrrolopyrimidine urea derivatives were synthesized and evaluated for their anticancer activity against colon cancer cell lines. Compounds showed the remarkable cytotoxic activity on HCT-116 wt cell line. The most potent compound 4c (IC = 0.

Cytokine expression profiles in Autism spectrum disorder: A multi-center study from Turkey.

Autism Spectrum Disorder (ASD) is a complex neurodevelopmental disorder characterized by impairments in communication and social interaction as well as restricted interests and repetitive behaviors. The pathogenesis of ASD is not completely understood, but a growing body of research has demonstrated that the immune response may be a contributing factor in the etiology and/ or ontogeny of ASD. The aim of this study was to determine the expression levels of IL-1β, IL-1α, IL-4, IL-6, IL-17, TNF-α and TGF-β in peripheral blood mononuclear cells of children with ASD and healthy controls in order to determine the contributions of cytokines to ASD.

Design, synthesis and in vitro apoptotic mechanism of novel pyrrolopyrimidine derivatives.

In this work we described the synthesis and evaluation of cytotoxic and apoptotic activity of novel pyrrolopyrimidine derivatives against A549, PC3 and MCF-7 cells. Among the synthesized compounds, 6b, 8a, 9a and 7a, 8b displayed the significant cytotoxic activities against A549 and PC3 cells with IC value of 0.35, 1.

Effect of indoor mold concentrations on daily symptom severity of children with asthma and/or rhinitis monosensitized to molds.

Little is known about the contribution of indoor molds to the symptoms of asthma and/or rhinitis in children monosensitized to molds. We aimed to investigate the effect of indoor mold spore concentrations on daily symptoms of asthma and/or rhinitis in children monosensitized to molds. Nineteen children with asthma and/or rhinitis sensitized only to molds recorded their daily symptoms and peak expiratory flow (PEF) values to the diaries, from February 2005 to January 2006.
