  2020-05-14

  

  Programmed cellular death or apoptosis is a process genetically controlled that plays an important role in cellular homeostasis, being an important defense mechanism to remove cells that have been infected, damaged or mutated (Smith and Smith, 2012, Wlodkowic et al., 2011). Nevertheless, apoptosis s

  Materials and methods Results Discussion Hydroxylation of proline in bacterial Agarose GPG/ME is one of the oxygen-requiring metabolic reactions, which needs efficient oxygen. Oxygen supply is always a rate-limiting step for tyrosinase production even though pure oxygen is purged in a bioreac

  Atypical collagen glycosylation The disaccharide Glc(α1-2)Gal(β1-O) decorating collagens is strongly conserved across the animal kingdom, yet for every rule, nature provides exceptions. The deep-sea worm Riftia pachyptila of the phylum Annelida represents an intriguing exception. R. pachyptila is

  2020-05-13

  

  Role of ROS signaling in regulating cell death pathways has been well established. Involvement of CLIC1 in ROS production has been studied earlier. It was observed that macrophages from clic1 mice showed ~30% decrease in cellular ROS generation which effects macrophage function (Jiang et al., 2012).

  2020-05-13

  

  A recent study revealed that in human glioma cells, DNA-PKcs interacted with the regulatory γ subunit of AMPK and positively regulated AMPK phosphorylation and activation under glucose-deprived conditions. This suggested that DNA-PK is an important regulator of AMPK activation in response to energy

  2020-05-13

  

  Of the acidic hydroxyazoles involved, hydroxypyrazole had the weakest acidic profile (pKa in the range of 6–7), although highly deprotonated at physiological pH. During hit optimization, the two pyrazole ring positions available for substitution provide an opportunity for a better exploration of the

• One step in pyrimidine biosynthesis

  2020-05-13

  

  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

  Nanocomposite films with a GNP-DNA filler concentration of 20 wt%, 30 wt%, and 40 wt% were investigated by electrical impedance spectroscopy before and after UV-C irradiation (Fig. 2). EIS data were fitted to a RC-circuit model and surface resistivity values were calculated from the fitted resistanc

  EphB4 as a therapeutic target in cancer Eph receptors and ephrins are promising new therapeutic targets in cancer. Various strategies have been employed to evaluate the interference of tumor-promoting effects or the enhancement of tumor suppressive effects. The inhibition of the Eph-ephrin system

  The growth inhibitory effect of PGE2 has been linked to the ability of Gs coupled PGE2 receptors EP2 and EP4 to mediate elevation of cAMP [22], [23]. Evidence suggests that this mechanism may not be the key cause of growth inhibition [24]. In various cell types, EP4 receptor has been shown to utiliz

  Enzyme activations Activated proteinases can unleash a deluge of tissue damage (Zucker et al., 2009). Once activated, the essential enzymes such as serine proteases and cysteine proteases cannot discriminate between self and non-self, burning away self-tissues (Chien et al., 2009, Laskar et al.,

  The Inhibitor of APoptosis (IAP) proteins were first identified as gene products of baculovirus that inhibited apoptosis of infected insect PHA-767491 (Clem et al., 1991, Crook et al., 1993). Subsequently, the mammalian IAP family was identified (Rothe et al., 1995, Uren et al., 1996). All members o

  CCR7 is another chemokine receptor that is upregulated in CLL [3], [61], [71], [96] and is believed to play a role in enabling cell entry into lymph nodes [97]. Higher mRNA and protein expression of CCR7 has been observed in unmutated compared to mutated IGHV CLL [46] and increased expression has be
