  2020-12-07

  

  In general, cellular senescence is considered a programmed response to stress that can be activated by oxidative stress, irradiation or action of substances or drugs. These stressors cause DNA damage and, through the action of specific proteins (p53 and p21), lead to cell senescence (di Fagagna, 200

  Introduction Structure of the Ku heterodimer associated to DNA The atomic structure of the Ku heterodimer, alone and bound to a small DNA fragment, was recently determined (Walker et al., 2001) and has significantly improved our understanding of DNA recognition by DNA-PK holoenzyme (Fig. 3). B

  The related catalytic regions of the human DNA ligases contain three domains, a DNA binding domain (DBD), a nucleotidyl transferase domain (NTase) and an oligonucleotide/oligosaccharide-fold binding domain (OBD) (Ellenberger and Tomkinson, 2008). Similar to DNA ligase I, the DNA ligase III polypep

  Introduction Lung cancer is the leading cause of cancer-related death worldwide, accounting for more than 1.5 million deaths in 2012. Non–small-cell lung cancers represent approximately 85% of lung neoplasms; among these, squamous cell carcinomas (SCC) account for approximately 30% of cases. The

  The physiological role of the UCNs in the regulation of the HPA axis is still under debate (Fekete and Zorrilla, 2007, Suda et al., 2004). UCN 1 was proved to increase the plasma ACTH and corticosterone levels in rats (Bagosi et al., 2014, Vaughan et al., 1995), whereas UCN 2 and UCN 3 were shown to

  Distribution of DGTS in basidiomycete fungi has been demonstrated to be heterogeneous. In certain fungal taxons, such as Agaricales, Polyporales and Russulales, there are species that synthesize and species that do not synthesize DGTS that belong to the same order or even family (Dembitsky, 1996, Va

  As demonstrated by Mak and colleagues, ERβ is known to be a part of the NFκB-HIF-1α signaling pathway during hypoxia as well as chronic inflammation of prostate (Mak et al., 2015), therefore in the next part of the study, we evaluated whether ZEA-induced ROS production is also associated with NFκB-H

  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 M

  Several questions remain to be addressed. The hormones and metabolites that modulate expression of EERγ in the steps leading to maturation need to be identified to learn more about physiological and pathophysiological regulation of EERγ in β cells. Considering that ERRγ repressed cell cycle genes i

L-NAME treatment did not modify the contractility detected in ischemic control hearts but annulled the actions of BZ acquiring LVDP values up to 40% (Fig. 4 A).

  Our results indicate an OT-specific activation of PKR that inactivates eIF2a and may, by this means, reduce protein translation by utilizing only select sensors and mediators of the UPR (i.e., avoiding significant PERK activation). Interferon is a PKR activator [32] that temporarily subdues cellular
