The double-stranded RNA (dsRNA)-activated protein kinase (PKR) provides a fundamental control step in the regulation of protein synthesis initiation through phosphorylation of the alpha subunit of eukaryotic translation initiation factor 2 (eIF-2alpha), a process that prevents polypeptide chain initiation. In such a manner, activated PKR inhibits cell(More)
The integrity of the sperm genome and epigenome are critical for normal embryonic development. The advent of assisted reproductive technology has led to an increased understanding of the role of sperm in fertilization and embryogenesis. During fertilization, the sperm transmits not only nuclear DNA to the oocyte but also activation factor, centrosomes, and(More)
The nuclear factor 1 (NF-1) motifs, NF-1 II/III, In the two 98-bp repeats of the transcription-regulatory region of JC virus (JCV), have a critical role in brain-specific transcription from the JCV early promoter-enhancer. In this study, the role of these motifs in transactivation of the JCV late promoter-enhancer (JCVL) was examined in differentiating(More)
BACKGROUND This case-control study was designed with the aim of evaluating the role of sperm, oxidative stress and DNA damage in idiopathic recurrent pregnancy loss (iRPL). This pilot study is the first study done on the Indian population which reports the association between DFI, TAC and ROS in couples experiencing iRSA. METHODS Twenty infertile men with(More)
PURPOSE To screen the paired box gene 6 (PAX6) gene in irido-fundal coloboma. METHODS The entire coding region of PAX6 including intron-exon boundaries was amplified from cases (n=30) and controls (n=30). All sequences were analyzed against the ensemble sequence (ENSG00000007372) for PAX6. RESULTS DNA sequence analysis of patients and controls revealed(More)
Transcription of the human polyomavirus JC virus (JCV) genome is regulated by cellular proteins and the large tumour (T) antigen. Earlier studies led to the identification of nuclear factor-1 (NF-1)-binding sites in the JCV enhancer by DNase I protection assays of extracts from retinoic acid (RA)-differentiated P19 embryonal carcinoma (EC) cells. In this(More)
