Molecular combing technology is an important new tool for the functional and physical mapping of genome segments. It is designed to identify amplifications, microdeletions, and rearrangements in a DNA sequence and to study the process of DNA replication. This technique has recently been used to identify and analyze the dynamics of replication in amplified.. Read More»

DNA replication, together with repair mechanisms and cell cycle control, are the most important cellular processes necessary to maintain correct transfer of genetic information to the progeny. These processes are well conserved throughout the Eukarya, and the genes that are involved provide essential information for understand.. Read More»

The alternative forms of the alleles in biallelic genes display a synchronous pattern of replication that is different from genes subjected to monoallelic expression, which exhibit an asynchronous mode of replication. The present study sought to gain insight into changes in the allele-specific replication timing in phenotypically normal humans with balanc.. Read More»

The trans-translation pathway, mediated by the transfer messenger RNA (tmRNA; encoded by the ssrA gene) and the SmpB protein (tmRNA-binding protein expressed in Salmonella enterica), which is conserved in bacteria, is required for various cellular processes. A previous study has shown that trans-translation is required to ensu.. Read More»

Intrinsically bent DNA is an alternative conformation of the DNA molecule caused by the presence of dA/dT tracts, 2 to 6 bp long, in a helical turn phase DNA or with multiple intervals of 10 to 11 bp. Other than flexibility, intrinsic bending sites induce DNA curvature in particular chromosome regions such as replication origi.. Read More»

DNA damage activates several mechanisms such as DNA repair and cell cycle checkpoints. The Saccharomyces cerevisiae heterotrimeric checkpoint clamp consisting of the Rad17, Mec3 and Ddc1 subunits is an early response factor to DNA damage and activates checkpoints. This complex is structurally similar to the proliferating cell nuclear antigen (PCNA), which.. Read More»

A recent paper (Casseb et al., 2016) published in the journal Genetics and Molecular Research described the interesting concept that dengue virus (DENV)-4 infection, in the human cell line A-549, leads to the downregulation of expression of key components of microRNA (miRNA) biogenesis, such as Drosha, Dicer, and DGCR8. For th.. Read More»

The bioactive compounds proceraside A, frugoside and calotropin, which were extracted from the root bark of Calotropis procera (Aiton) W.T. Aiton (family Asclepiadaceae), were recently reported to inhibit the growth of inhibition against various human cancer cell lines in vitro. However, their modes of action have not been cle..

Chromatin is thought to modulate access of repair proteins to DNA lesions, and may be altered by chromatin remodelers to facilitate repair. We investigated the participation of chromatin remodelers and DNA repair in 5-fluorouracil (5-FU) cytotoxicity in Saccharomyces cerevisiae. 5-FU is an antineoplastic drug commonly used in clinical settings. Among the .. Read More»
