  2019-12-06

  

  Like all other cellular processes, ubiquitination is also tightly regulated; more so, as myriads of pathways are controlled via this conjugation and dysregulation of ubiquitination has been implicated in various diseases including cancer [16], [17]. Quite a few of such regulatory mechanisms that con

  The major regulator of radiation sensitivity Tumor cell resistance to radiation is a big issue for radiation therapy, and a major concern of radiation oncologist. Understanding the regulation mechanism of radiation sensitivity is still a research hotspot. Increased sensitivity to ionizing radiati

  After incorporation of random R788 by TdT during heavy-chain rearrangements, both TdT and pol λ may perform in trans polymerase activity (in unknown proportions), whereas synthesis of the complementary strand can only be achieved by pol λ using its gap-filling activity, which TdT lacks because of it

  Why then is leading-strand DNA synthesis reduced relative to lagging-strand synthesis in rad53-1 mutant guanylyl cyclase under replication stress? To gain insight into this question, we first determined whether the firing of late origins in rad53-1 mutant cells contributes to compromised leading-st

  Introduction Diacylglycerol kinase (DGK) is a lipid-metabolizing enzyme that phosphorylates diacylglycerol (DG) to produce phosphatidic Brilliant Blue G (PA) [[1], [2], [3], [4]]. DG and PA act as lipid second messengers in a wide variety of biological processes. Ten DGK isozymes (α, β, γ, δ, η,

  1-Imidazo[2,1-]purine-2,4(3,8)-diones were another cluster of compounds identified from the Chembridge screen (). A benzyl group at the R2 position was preferred over a phenyl or 2-phenylpropyl (. and ), and -substitution of the benzyl group increased potency to the nanomolar level ( IC=0.20μM . ).

  Expression of DNMTs during testicular development In most multicellular organisms, male and female germ cells are the origin of development of an organism, and they provide inheritance of genetic and epigenetic information across the generations. Primordial germ cells (PGCs) derive from a subset

  The promoter regions of all MdDGKs examined here included many hormone-responsive and stress-responsive elements, such as ABRE, MBS, TC-rich repeats, HSE, and LTR. Despite assumptions about how those promoters might control expression in response to environment stimuli, we found several exceptions.

  Effects of estrogen on vascular function Atherosclerosis is a chronic inflammatory condition of the vascular wall (Figure 1) that can be converted to an acute clinical event by the induction of plaque rupture or erosion, leading to thrombosis [58]. This perpetuating process is characterized by ph

  Conclusions and future directions In recent years we saw major advances in our knowledge of H2A-DUB biology, with discovery of novel mammalian H2A-DUBs, better understanding of their biochemical properties, and development of several animal models to address their in vivo functions. However at pr

  Early developments Historically, the advent of SMEPT can be traced to the 1980′s, where the first example of localized prodrug conversion was achieved using a judiciously placed enzyme – in order to achieve a localized feed of 5-fluorouracil (5-FU). Immobilization of E. coli-derived cytosine deam

  In addition to cleaving ubiquitins off modified proteins, DUBs can also cleave between ubiquitin moieties within a polyubiquitin chain to edit the ubiquitin signal. DUBs employ different strategies to recognize polyubiquitin (Figure 1). DUBs that rely only on interactions on the S1 site tend to be D
