  Estrogens: Definition and history The term “estrogens” refers to a group of female hormones, including estrone, estradiol, estriol, and estretrol (Fig. 1). Chemically, estrogens belong to the family of organic compounds known as steroids. As such, their core structure is composed of 17 carbon-carbo

  Introduction Concrete is one of the most commonly used materials in the construction industry and its raw material is available throughout the world. Concrete is derived from ordinary Portland cement and is used for the construction and development of infrastructures. Research shows that demand f

  In addition to providing substantial insight into substrate recognition, structural studies have revealed important details about mechanisms of glycosylation and HCF-1 cleavage [28,30,33]. Activation of the nucleotide-sugar is accomplished through interactions of the β-phosphate with the N-terminus

  2019-09-24

  

  As a co-factor, CIITA lacks the ability to recognize and directly bind to specific DNA elements to regulate transcription; instead, it relies on interaction with sequence-specific transcription factors (TFs) to be recruited to the chromatin. Therefore, the observation that CIITA binds to a specific

  2019-09-24

  

  The RING domain was previously considered sufficient to confer ubiquitination by RING-type E3 ligases. However, recent reports have shown that sequences closest to the RING domain are also important in E3 ligase function. Residues like Tyr193 in RNF4 [40], Phe296 and Arg294 in BIRC7 [31], and Lys65

  Introduction Cholesterol plays a pivotal role as a constituent of biological membranes and as a precursor for vitamins, hormones and bile acids. Accordingly, its production, distribution, and elimination must be tightly regulated at the cellular and organismal level. Accordingly, dysregulated chole

• ATP dependent DNA ligases in vertebrates

  2019-09-24

  

  ATP-dependent DNA ligases in vertebrates are divided in three families [7]. Family I DNA ligases are responsible for sealing the nicks during DNA replication and in long-patch base excision repair (BER). Family III DNA ligases are involved in short-patch BER. Lastly, family IV DNA ligases are involv

  Discussion The differences in the kinetic properties of L-AmDH and LeuDH presented herein reflect a different kinetic mechanism. When compared to its parent enzyme, L-AmDH displayed a different substrate binding order, lower affinity for the keto substrate, and stronger product inhibition. The tw

  Use of recombinant collagen to study DDR–collagen interactions Synthetic peptides have proven highly valuable in replicating the characteristics of collagen and in defining the sites on collagen essential for binding and studying protein–collagen interactions. There are, however, disadvantages to

  Diclofenac, ibuprofen, and meloxicam are considered among the most commonly used NSAIDs in many countries [4]. Cardiovascular events were reported with these NSAIDs in several clinical studies. In this study, we provide novel information that diclofenac and ibuprofen altered gene expression and may

  Although high concentrations of SCR7-G and SCR7-R inhibited LigIV as reported [11], the SCR7 derivatives were more effective inhibitors of LigIIIα and, in particular, LigI. Although it is possible that differences in the DNA substrate underlie this discrepancy, it appears more likely that this refle

  Deregulated Wnt signaling, either due to pathway mutations or otherwise aberrant pathway activity, is common in CLL [81], [82]. In addition to targets described above, alvocidib also inhibits glycogen synthase kinase 3 (GSK3)-β at higher nanomolar concentrations [37]. Despite intuition and experimen

  We have previously reported that CK2 is downregulated in senescent human lung fibroblast IMR-90 cells, aged rat tissues, and aging nematodes [17,18]. CK2 downregulation induces cellular senescence via the PI3K-AKT-mTOR-reactive oxygen species-p53-p21Cip1/WAF1 pathway in human cells [[19], [20], [21]
