2023-12-12
Nowadays, more than 500 kinases have been identified of human genome [2]. Imatinib (Gleevec) was the first tyrosine kinase inhibitor approved by the US Food and Drug Administration (FDA) for the treatment of chronic myeloid leukemia [3], and kinases have become an attractive target for the developme

2023-12-12
In many thymidine phosphorylase inhibitor α1-AR mediated activation of PLC has been shown to be the downstream process for NA-induced signalling. The activated PLC initiates subsequent signalling by breakdown of PIP2 to IP3 and DAG (Fisher and Agranoff, 1987) and the process continues. To confirm i

2023-12-12
Among the most important Ca regulatory mechanisms are the Plasma Membrane Calcium ATPase (PMCA) and Sarcoplasmic Reticulum Calcium ATPase (SERCA). These pumps belong to the family of P-ATPases, which share the formation of an acid-stable phosphorylated intermediate as part of their reaction cycle. P

Further important evidence for G protein signaling on early endosomes has been subsequently obtained for the β2-adrenegic receptor using fluorescently-tagged conformation-sensitive nanobodies selectively recognizing the active receptor and Gs protein [43]. More recently, our group used a combinatio

At the outset of targeting the two Gln756 side-chain rotamers, it was unclear which rotational isomer would lead to more potent ASK1 inhibitors. While such a preference might have been anticipated, the cohort of ASK1 inhibitors in Table 3 did not provide any guidance regarding which of the Gln756 am

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

Currently, NSAIDs which achieve antineoplastic actions mainly through apoptosis are emerging choice in chemotherapy. Their antineoplastic effects were demonstrated before in tumor-bearing models [5], [6], [7]. Through in vitro cell models, we identified an indomethacin-activation of ceramide/PP2A/Ak

In addition, understanding the relationship between human metabolic processes and dietary antioxidant intake would provide opportunities for altering the diet to improve health (Prior, 2015). Prior et al. (2007) emphasized that excess reactive oxygen species, which occurred during the metabolism of

This progressive behaviour is summarized in Fig. 4, which depicts the variation in convexity of the obtained cut-off patterns for the series of six antioxidants. The form and degree of convexity of the obtained cut-off curves should in principle correlate with the AOs hydrophobicities, and therefor

Although the interactions of PhLP with Gβγ and its other partners have been convincingly documented through in vitro studies, it is not clear how PhLP controls ras inhibitor signaling in vivo. C. elegans provides a powerful genetic model to analyze Phosducin function and study its interacting partn

Overexpression of AR in a transgenic mouse model leads to a capsular cataract phenotype involving proliferation and formation of a fibrotic plaque of cells reminiscent of cells at the posterior AVL-292 in PCO [17]. To investigate the molecular mechanism that could link AR expression to this phenotyp

Aldose reductase (AR), is an NADPH-dependent aldo-keto reductase very well studied as a catalyst of glucose conversion to sorbitol in the polyol pathway [11], [12]. In the diabetic lens characterized by chronically high levels of glucose, AR is responsible for production of high levels of sorbitol a

Interestingly, hypoxia and an enhanced Warburg effect ultimately lead to increased lactate production. The accumulation of lactate results in an acidic tumor microenvironment, which induces local inflammation. Lactate also promotes the polarization of macrophages that express immunosuppressive argin
