  Introduction Double strand break (DSB) is the most deleterious damage that threats DNA integrity. This frequent damage arises from environmental stress like UV, chemical agents or ionizing radiations (IRs). Although environmental stress does not lead directly to DSB, it produces kynurenine damage,

  During germ cell development in mouse, de novo Dnmts regulate the genomic imprinting and silence of repeat elements. Dnmt3A methylated H19, Dlk1/Gtl2, and Sine B1, whereas Dnmt3B methylated microsatellite repeat elements, the two Dnmts co-methylatedRasgrf1, IAP, and Line1 repeat elements (Lucifero e

  In conclusion, the present study demonstrates that E2\'s antiapoptotic effects are significantly reduced by coadministration of progestogens. The combination of E2 and progestogens resulted in diverging effects on the expressions of ERs and PRs, which induced different effects on the cell growth of

  Another interesting finding from the present study is that silencing of ERRγ suppressed the expression of HSD17B1 in extravillous trophoblasts. HSD17B1 is a key enzyme in regulating estrogen activity and has been shown to promote the proliferation and migration of estrogen-dependent breast cancer Th

  Conclusions In conclusion, the substrates 18c–18e all produced highly fluorescent colonies with the panel of Gram-negative microorganisms. This has been attributed to the combination of two synergistic effects; the wide distribution of l-alanylaminopeptidase in Gram-negative microorganisms and th

  For immobilization of enzymes, natural polymers depict several outstanding features as support. These materials are inert, non-toxic, biodegradable and biocompatible. As well as, they can be treated with different functional groups easily by chemical reactions that occur under gentle conditions in a

  Introduction Concern has been raised over free estrogens (estrone [E1], 17ß-estradiol [E2] and 17α-ethynylestradiol [EE2] particularly) in the past decade due to their endocrine disrupting effects on environmental biota [1], [2]. Estrogens are excreted by vertebrates primarily as sulfate or glucu

  Oxidation of N-hydroxyguanidine 1 by DbH was studied by HPLC and some oxidation products for 1 could be characterized. The compounds generally observed with iron-containing systems are 4-methoxyphenylurea 11 and 4-methoxyphenylcyanamide 12 (Fig. 2). Oxidation of N-(4-chlorophenyl)-N′-hydroxyguanidin

  Boulares group [82] has demonstrated that the NF-κB1/p50 NF-κB, a family member of type I NF-κB, is an excellent substrate for DNA-PK, which-dependent phosphorylation of NF-κB1 at serine 20 appears to enhance its binding to DNA as either a homodimer or a heterodimer with p65 NF-κB and the ability of

  Cancer has been linked to both genetic and epigenetic changes. Epigenetic modifications, mainly DNA methylation at CpG dinucleotides, affect the regulation of gene transcription without altering the gene\'s sequence. Short sequences rich in CpG dinucleotides (i.e., CpG islands) are often found in th
