Kim et al. reported for bioactive compounds originating from the endemic species in Korea, the hexane and EtOAc fractions of the MeOH extracts from the roots of Dystaenia takeshimana (Nakai) Kitagawa (Umbelliferae) showed cyclooxygenase-2 (COX-2) and 5-lipoxygenase (5-LOX) dual inhibitory activity b

Finally, we demonstrated for the first time that the physiological combinations of estradiol and progesterone levels of premenopausal and postmenopausal women efficiently stimulated the growth of T47D spheroids while clinically relevant concentrations of TPA and UPA suppressed the growth of T47D sph

Involvement of p38 MAPK pathway The NF-κB signal transduction cascade is a major stress response signaling pathway for the COX-2 gene expression. In mice and humans, the COX-2 promoter has contact us for many transcription factors, including NF-κB in the 5′ region of the COX-2 gene [11], and the

Importantly, our in vivo data fit to the in vitro data, further confirming the synergistic effect of XJD and gefitinib on the inhibition of lung cancer and the regulation of SP1, HOTAIR, and EP4 α-mangostin synthesis levels. The doses of XJD used were based on our previous in vivo study (Zhao et al

Another enzyme class that has emerged as a potential alternative to P450s are the so-called ‘unspecific peroxygenases’ (UPOs). They also contain a heme but are extracellularly expressed fungal enzymes that are often more stable than P450 monooxygenases. Importantly, UPOs use H2O2 instead of O2 as th

In conclusion, the data suggest that doses of COX-2 inhibitors and EP1 receptor antagonists which have previously been reported to exert disease modulating or antiepileptic drug potentiating effects do not negatively affect seizure control in temporal lobe epilepsy. The contrasting impact of the EP1

For immobilization of enzymes, natural polymers depict several outstanding features as support. These materials are inert, non-toxic, biodegradable and biocompatible. As well as, they can be treated with different functional groups easily by chemical reactions that occur under gentle conditions in a

In our opinion, the precise function of AE of S. mansoni (Sm32) remains unclear, and accurate knowledge of the three dimensional structure of this enzyme would be valuable for a better understanding the molecular basis of many of its properties, including its role in the host-parasite interaction, a

2019-11-07
Our knowledge of DDR-induced signaling pathways is still fragmentary. In particular, we do not know which signaling effectors interact with the phosphorylated receptors and how different effectors are linked to the control of specific cellular functions. The DDRs are at the interface between RTKs an

Two-photon microscopy experiments demonstrated that most contacts between GC B and Tfh cells are of short duration (about 2 min), and only about 4% of these contacts lead to the formation of stable conjugates (5 to 60 min) (Allen et al., 2007). Similarly, during extrinsic peptide stimulation, some r

The biological significance of DNA ligases is attributed to their function in DNA replication, recombination and/or DNA repair [1], [2]. In vertebrates, three different DNA ligases I, III and IV are recognized. DNA ligase I is essential for the Okazaki fragments’ ligation during lagging-strand DNA s

Recent studies have shown arsenic could cause autophagic cell death in malignant cells, including leukemia and malignant glioma mitomycin [16], [17]. However, at present, little is known about the consequences of arsenic-treated urothelial cells in autophagy and expression of its related proteins. T

It is not precisely known which of the intramolecular interactions created by the SH2 domain, the SH3–SH2 linker and the SH2–kinase linker are essential for the catalytic activity of Csk or how these interactions regulate Csk activity. Thus far it has been shown that site-directed mutagenesis of SH3

Since the number of peptides hydrolized by PEP is quite large, it is not easy to relate the increase of enzymatic activity with the altered changes of a concrete peptide. However, it is noticeable that imbalances of several natural substrates of PEP [6], such as angiotensins, bradykinin, vasopressin

EBV Infection Epstein–Barr virus (EBV, human herpesvirus 4) was discovered 50 years ago, when Epstein, Achong, and Barr used electron microscopy to identify viral particles in Burkitt\'s lymphoma cells. It belongs to the lymphocryptovirus (LCV) genus of the gammaherpesvirus subfamily (Fig. 1A). T
