The 5′ regulatory region of the human fetal globin genes is a gene conversion hotspot
(2008)The human fetal globin genes consist of the first mammalian genomic loci for which gene conversion was reported. To date, 14 gene conversions have been described in the human Gγ- and Aγ-globin genes, the vast majority of ... -
Alterations of microRNAs in solid cancers and their prognostic value
(2010)MicroRNAs (miRNAs) are evolutionarily conserved, naturally abundant, small, regulatory non-coding RNAs that inhibit gene expression at the post-transcriptional level in a sequence-specific manner. Each miRNA represses the ... -
Anti-invasive effects of CXCR4 and FAK inhibitors in non-small cell lung carcinomas with mutually inactivated p53 and PTEN tumor suppressors
(2017)Non-small cell lung carcinoma (NSCLC) is the most common type of lung cancer. At the time of diagnosis, a large percentage of NSCLC patients have already developed metastasis, responsible for extremely high mortality rates. ... -
AtHESPERIN: A novel regulator of circadian rhythms with poly(A)-degrading activity in plants
(2016)We report the identification and characterization of a novel gene, AtHesperin (AtHESP) that codes for a deadenylase in Arabidopsis thaliana. The gene is under circadian clock-gene regulation and has similarity to the ... -
The autophagic response to oxidative stress in osteoarthritic chondrocytes is deregulated
(2018)It has been reported that oxidative stress (OS) is involved in the pathogenesis of osteoarthritis (OA) and that defective autophagy is accompanying this age-related disease. Moreover, it has been proposed that induction ... -
Biochemical and genetic evidence for the presence of multiple phosphatidylinositol- and phosphatidylinositol 4,5-bisphosphate-specific phospholipases C in Tetrahymena
(2011)Eukaryotic phosphoinositide-specific phospholipases C (PI-PLC) specifically hydrolyze phosphatidylinositol 4,5-bisphosphate [PtdIns(4,5)P2], produce the Ca2+-mobilizing agent inositol 1,4,5-trisphosphate, and regulate ... -
Browning formation markers of subcutaneous adipose tissue in relation to resting energy expenditure, physical activity and diet in humans
(2017)Regular exercise and diet may contribute to white adipose tissue (WAT) conversion into a brown adipose-like phenotype that may increase resting energy expenditure (REE), leading to weight loss. We examined the relationship ... -
Clinical value of significance of hypoxia inducible factor-1α, glucose transporter-1 and carbonic anhydrase IX in rectal cancer after preoperative chemoradiotherapy
(2019)Purpose: The standard treatment of rectal cancer is surgery along with preoperative radiotherapy, administered alone or in combination with chemotherapy. Preoperative chemoradiotherapy (preCRT) is widely used as it allows ... -
Computational genomic analysis of PARK7 interactome reveals high BBS1 gene expression as a prognostic factor favoring survival in malignant pleural mesothelioma
(2015)The aim of our study was to assess the differential gene expression of Parkinson protein 7 (PARK7) interactome in malignant pleural mesothelioma (MPM) using data mining techniques to identify novel candidate genes that may ... -
Cytological and other aspects of pathogenesis-related gene expression in tomato plants grown on a suppressive compost
(2006)• Background and Aims: Recent studies have shown that certain composts may trigger indirect defence mechanisms by sensitizing the plant to create an increased state of resistance, similar to systemic acquired resistance. ... -
Decoding the reproductive system of the olive fruit fly, Bactrocera oleae
(2021)In most diploid organisms, mating is a prerequisite for reproduction and, thus, critical to the maintenance of their population and the perpetuation of the species. Besides the importance of understanding the fundamentals ... -
Developmental competence of heat stressed oocytes from Holstein and Limousine cows matured in vitro
(2021)The negative effects of heat stress on dairy cattle's fertility have been extensively studied, but the relevant knowledge for beef cattle is rather limited. The aims of this study were to investigate the effects of HS ... -
The Developmental Program of Murine Erythroleukemia Cells
(2002)Hematopoietic stem cells (HSCs) or early progenitors respond to external stimuli in bone marrow and differentiate into cell-restricted lineages of blood cells of limited life span. In leukemias, however, early hematopoietic ... -
Dexamethasone has a biphasic effect on the c-Jun mRNA expression in the fetal and adult rat lung, in vivo
(1999)Glucocorticoids are a very potent therapy for the treatment of asthma as well for lung maturation in the prematurely newborn animals and human. It has been demonstrated that glucocorticoid receptors antagonize the actions ... -
