  Enzymes repairing alkylated DNA Induction of the Ada regulon Methylated Ada is a strong activator for ada and alkA promoters. Although much weaker than the methylated form, unmethylated Ada acts alone as an activator for ada and alkA promoters. In contrast, the unmethylated protein present in

  Keratin 8 (K8) has been identified as the first intermediate filament expressed during development in amphibians and mammals. In zebrafish, a type II cytokeratin 8 (zf-K8) cDNA has been cloned. zf-K8 gene was maternally inherited and expressed in all surface cells throughout the embryonic stages old

  Another novel finding of our study was that the global 5 hmC was down-regulated and was associated with a substantial reduction of TET expression in the PE placentas compared with the controls. The decreased global 5 hmC level was consistent with the increased global 5 mC level in the preeclamptic p

  2021-03-17

  

  Prostaglandins (PGs), in particular PGE2 and PGF2α, play pivotal roles in human parturition by stimulating cervical ripening, myometrial contraction and fetal membrane rupture (Challis et al., 1997). In human pregnancy, the amnion is the principle source of PGE2 (Duchesne et al., 1978). In the amnio

  In conclusion, our study has demonstrated that PGE2 stimulates expression of survivin in hepatocellular carcinoma cells. Although there are 4 subtypes of EP receptors, the EP1 receptor appears to be the predominant receptor that regulates PGE2-induced expression of survivin, mainly through trans-act

  Acknowledgments Multicellular organisms respond rapidly, and adapt to cellular stress to maximize cell survival. The cellular stress response, also called (ISR), is universally conserved and independent of the stressor. ISR induces rapid, transient reprogramming of cellular protein translation

  Through an unknown mechanism, RING/Ubox-type E3 dimers and the N-terminal tail have been shown to function as a modulator of full E3 ubiquitin ligase activity [27]. LRSAM1 promotes a significant enhancement in the formation of the high-molecular-weight products or E3 activity when the RING domain is

  Introduction O6-Methylguanine-DNA methyltransferase (MGMT) is a DNA-repair enzyme that specifically transfers alkyl adducts from the O6 position of guanine to the cysteine residue (Cys145) in its active site. In cancer cells, this ability of MGMT disrupts the cytotoxic actions of alkylating antic

  Covalent inhibitors are well suited for targeting the E1 Naltrindole hydrochloride of Ubl modifications. Because the E1 enzymes in Ubl modifications, such as the SUMO E1 and Atg7, have a slow turnover rate (Boggio et al., 2004), prolonged inhibition can be achieved without requiring compounds to be

  Primases are classified into two major groups: first, the DnaG primases, found in bacteria and bacteriophages, and second, the archaeoeukaryotic primases. Remarkably, bacterial and archaeoeukaryotic primases have no structural similarity and, presumably, evolved independently (Leipe et al., 1999). T

  The aniline R2 group was extensively explored and a large variety of substitution was tolerated at several positions on the aryl ring (). Notably, substitution at the 3-position often gave increased potency. Increasing lipophilic bulk at this position gave increasing potency within an ether series (
