  Our data supports the conclusion that the exonuclease activity thought to be intrinsic to Artemis is not a component of the Artemis polypeptide. Many possibilities exist to explain the presence of the exonuclease activity in less-pure fractions of Artemis. It is possible that the exonuclease is simp

  Mammalian DGKs: current knowledge Despite our understanding of prokaryotic DGKs, our limited understanding of the structure of mammalian DGKs is a major gap in our knowledge. Importantly, major differences exist between prokaryotic and mammalian enzymes often revealing the fact that structural fe

  2021-06-08

  

  One step in pyrimidine biosynthesis is conversion of l-dihydroorotate (DHO) to orotate (ORO), under action of the enzyme dihydroorotate dehydrogenase (DHODH, EC 1.3.99.11), which contains a flavine (FMN) as redox cofactor [1]. In this transformation, electrons resulting from DHO oxidation are transf

  DNA promoter hypermethylation is an important mechanism in epigenetic modulation of gene expression.[16], [17], [18] When the promoter CpG island of a gene is hypermethylated, the transcription and its associated function of the gene will be subsequently altered.[19], [20], [21] In human cancers, we

  Previously, to detect CDKL5 activity, we used a radioactive phosphorylation assay with amphiphysin 1 protein as a substrate [,,]. However, it is necessary to establish a safe and rapid method for analyzing CDKL5 mutant activity. Here, we report a new method for investigating autophosphorylation acti

  ICV injection of UCN2 or UCN 3 performed in the morning of the 8th day (12h after the last IP administration) seems to increase further the time spent in the open arms of mice exposed to saline or nicotine treatment. Interestingly, in mice exposed to saline treatment ICV injection of UCN 2 or UCN 3

  Arsenic is an endocrine disruptor with estrogenic activity. Further study has shown that arsenic exposure can significantly increase the expression of estrogen receptor-related genes, steroid metabolism-related enzymes and lung cancer-related genes in the lung tissues of female mice on the occurrenc

  It is now well accepted that increased local estrogen levels are associated with both the onset and growth of breast cancer. Tissue concentrations of estradiol (E2) in breast cancer are 10 times higher than that found in plasma [12]. Breast cancer tissues also contain increased activity and expressi

  Here, we report for the first time that EphB4 contains two NLS sequences and localises to the nucleus. This is mediated via an importin-α pathway and we show that EphB4 could potentially have a direct role in gene regulation. These data provide new insight into Eph receptor localisation and action

  Although PKCδ in cancer ym express mg is known to promote antiapoptotic signaling, a cleaved form of PKCδ, δCF, has been reported to play a contrasting role in enhancing apoptosis (Reyland, 2007), and these complex functions appear to be cell-type dependent (Basu and Pal, 2010). In NSCLC, full-lengt

  Regardless of its effect on EBV infection, the chemokine system has been found to be regulated in both nasopharyngeal cancer and Hodgkin lymphoma. As such, Hodgkin and Reed–Sternberg (HRS) cells from Hodgkin lymphoma and nasopharyngeal carcinoma cells have been shown to express CXCL8 and CCL17. Furt
