Endoplasmic reticulum stress (ERS) and insulin signaling impairment are commonly observed in Alzheimer's disease (AD), but the association between these two factors in AD has not been carefully studied. In peripheral insulin signaling impairment, ERS interferes with insulin signaling through c-Jun. N-terminal kinase (JNK)-dependent insulin receptor substance-1 (IRS-1) serine phosphorylation. We conducted...
Here we analyzed in leaves the effect of FT overexpression driven by meristem-specific KNAT1 gene homolog of Arabidopsis thaliana (Lincoln et al., 1994; Long et al., 1996) on the transcriptomic response during plant development. Our results demonstrated that meristematic FT overexpression generates a phenotype with an early flowering independent of photoperiod when compared with wild type (WT) plants...
Chromatin remodeling complexes utilize the energy of ATP hydrolysis to remodel nucleosomes and have essential roles in transcriptional modulation. Increasing evidences indicate that these complexes directly interact with numerous proteins and regulate the formation of cancer. However, few studies reported the association of polymorphisms in chromatin remodeling genes and lung cancer. We hypothesized...
Gliomas are the most frequent primary tumors of the brain, and there is no successful treatment for highly malignant gliomas. MicroRNAs (miRNAs) are involved in a variety of biological processes. Recent studies showed that miR-150-5p and miR-133a are downregulated in various human malignancies, and one of target mRNAs was shown to be membrane-type 1 matrix metalloproteinase (MT1-MMP) mRNA. However,...
Immunogenes (i.e., genes related to the immune system and its functions) are involved in the predisposition to numerous traits and their variation contributes to the phenotypic variability observed among human groups. Turkish population presents particular genetic features since its genetic pool is an admixture of European, Middle-Eastern, and Central Asian ancestries. Here, we analyzed the haplotype...
Pancreatic ductal adenocarcinoma (PDAC) is the sixth most frequent cancer type in the Czech Republic with a poor prognosis that could be improved by an early detection and subsequent surgical treatment combined with chemotherapy. Genetic factors play an important role in PDAC risk. We previously identified one PDAC patient harboring the Slavic founder deleterious mutation c.657del5 in the NBN gene,...
Breast cancer is major public health problem predominantly effects female population. Current therapeutic approaches to deal with breast cancer are still lack of effectiveness. Thus, identifying/developing novel strategies to fight against breast cancer is very important. The frequent deletions at 8p21.3-22 chromosomal location nearby D8S254 marker enabled the discovery of a novel tumor suppressor...
Biological processes involve much complex interplay between cellular molecules at different molecular levels, and this interplay may exhibit various co-expression patterns explicitly representing the cellular inner regulation mechanism. Whereas, coexpression patterns cannot be necessarily conserved across the different molecular levels for complex regulation processes involved even after transcripts...
Cisplatin is one of the most effective chemotherapeutic agents for the treatment of lung cancer. However, the acquired resistance occurred in cancer cells limits the clinical application of cisplatin. MCL-1, which is an important member in the pro-survival Bcl-2 family, plays a critical role in multidrug resistance (MDR). The aim of the present study is to investigate the value of Pan-Bcl-2 inhibitor...
Alternative pre-mRNA splicing provides a source of vast protein diversity by removing non-coding sequences (introns) and accurately linking different exonic regions in the correct reading frame. The regulation of alternative splicing is essential for various cellular functions in both pathological and physiological conditions. In eukaryotic cells, this process is commonly used to increase proteomic...
Unlike the classical gonadotropin-releasing hormone (GnRH1), the second mammalian isoform (GnRH2) is ubiquitously expressed, suggesting a divergent function. Indeed, we demonstrated that GnRH2 governs LH-independent testosterone secretion in porcine testes via interaction with its receptor (GnRHR2) on Leydig cells. Transient transfections with luciferase reporter vectors containing 3009bp of 5′ flanking...
