  We showed that activation of the ATM/ATR pathway leads to over-replication through suppression of CDK1 activity, consistent with previous findings that suppression of CDK1 activity is involved in the polyploidization of megakaryocyte and trophoblast cells [36], [37], [38], [39]. Suppression of CDK1

  The uterine muscle also changes to meet the demands of pregnancy. Over the course of pregnancy, the myometrium undergoes structural remodeling to accommodate a growing fetus, followed by a functional switch from quiescent to contractile characteristics for parturition. Studies on the mouse model ind

  Somatostatin analogs also bind to somatostatin receptors. It has been reported that octreotide has a high affinity for hSSTR2, moderate affinity for hSSTR3 and hSSTR5, and does not bind to hSSTR1 or hSSTR4 (Ben-Shlomo and Melmed 2008). Compared to octreotide, pasireotide displays 40-, 30-, and 5-fol

  Autophagy and apoptosis have a very complex relationship, and the precise mechanism remains to be determined. At present, a large amount of research has confirmed that autophagy can protect the cell from apoptosis in special conditions such as nutrient deficiency or growth factors deprivation; the e

  2024-09-24

  

  Most human diseases (e.g., cancer, diabetes, and neurodegenerative diseases) are complex and multifactorial. Several investigations in the literature focused on new multi-target drug development, which implies active pharmacophores incorporation in one scaffold (Meunier, 2008, Lazar et al., 2004, Te

  2024-09-24

  

  F901318 is an orotomide, a novel class of antifungals, which inhibits pyridine biosynthesis by blocking dihydroorotate dehydrogenase (URA1) activity [137]. Although this pathway is conserved in humans, human URA1 is only 20% identical to its fungal homolog and it is inhibited 2000-fold less effectiv

  Although our sample size is not enough to conclude that there is no great genetic variation of the AR gene in most New World monkeys, it would be reasonable to state that the microsatellite region in the exon 1 of the androgen receptor gene of New World monkeys (platyrrhine) is relatively shorter th

  We approached the definition of AD with the distinction between a syndrome and a disease in mind. Some will argue that a specific syndrome, that is, a multidomain amnestic dementia (after other potential etiologies have been excluded), should define AD in living people. Our position, however, is t

  So far, many independent studies have linked cholesterol metabolism–related genes with AD, either by showing associations with specific polymorphisms or with differential Dihydrotestosterone levels (Beecham et al., 2014, Blain and Poirier, 2004, Lambert et al., 2009, Lambert et al., 2013, Leduc et a

  Within the PARP family, TIPARP is most evolutionarily conserved with PARP12 (ARTD12) and PARP13 (ARTD13) [27,28,41]. All three proteins contain at least one RNA-type CCCH zinc finger domain, a poly-ADP-ribose binding WWE domain and a PARP catalytic domain (Fig. 1). PARP13 is catalytically inactive,

  2024-09-23

  

  Adenosine receptors activate a number of signalling pathways involved in tissue survival including several mitogen-activated protein kinases (Fredholm et al., 2001). The common feature of all adenosine receptors is the positive coupling to ERK1/2, whilst A2B and A3 receptors can also activate the s

  In the presence of detrimental conditions, such as inflammation, hypoxia, ischemia trauma or neoplastic milieu, the extracellular levels of adenosine increase massively, reaching micromolar range [51,52]. In these pathological contexts, adenosine accumulation stems from increased extracellular depho

  In this scenario, the receptor tyrosine kinase inhibitors (TKI), sunitinib, an anti-angiogenic agent, was tested in phase III trial, leading to a longer progressing free survival when compared to interferon (median: 11 vs. 5mo, respectively, hazard ratio (HR) = 0.42; 95% CI: 0.32–0.54; Pnatural arom

  Drug resistance development often involves structurally un-related drugs and, specifically both conventional and targeted agents.
