Author contributions Conflicts of interest Introduction Current the 5-year survival rates for lung and pancreatic cancers are 18% and 8%, respectively. These low survival rates are partially because of the late diagnosis of one-half of cases, in which 5-year survival decrease to 4% and 3%,

Most xenobiotics undergo biotransformation before being excreted. Such biotransformation is classified into two phases. In the first phase, the lipophilic substrate is oxidized by the cytochrome P-450 (CYP450) enzyme system, which introduces a single oxygen ap-1 transcription factor into the molecu

Intriguingly, one E2 residue may serve as a molecular ‘gate’ to allow the C-terminus of ubiquitin to access the closed E2~Ub conformations favorable for ubiquitin transfer. This residue, Asp87 in UbcH5 family members, resides on one side of the opening that leads to the active site Cys (Fig. 4D). In

2021-08-30
The estrogen receptor(ER)-dependent signaling pathway plays an important role in bone metabolism by restoring the balance between osteoblastic bone formation and osteoclastic bone resorption [21]. ER has two major isoforms, ERalpha (ER-α) and ERbeta (ER-β), which mediate the effect of estrogen and o

Multiple sequence alignment of the proteins in the DGAT1 sub-family shows that there are about 41 conserved amino N1-Methylpseudouridine residues distributed over seven sequence motifs [74]. Unlike DGAT2, a large number of DGAT1 residues, including a majority of the conserved residues, are found in

It is important to note that CRF1 may be activated during acute stress and early phases of anxiety disorders (Coric et al., 2010, Ising et al., 2007), as well the administration of Astressin 2B into the lateral septum did not have an effect on anxiety-like behavior in low-stress conditions but had a

2021-08-28
The serotonin transporter gene () encodes an integral membrane protein that transports serotonin from the synaptic spaces into the presynaptic neurons. The encoded protein terminates the action of serotonin and recycles it in a sodium-dependent way. This protein is a target of psychomotor stimulants

A more refined picture of cholinesterase activity patterns may be obtained by measuring ChE activity of the same sample before and after addition of certain cholinesterase inhibitors, with differential specificity for different components of total ChE activity, such as BW284c51 (BW1,5-bis-(4-allyldi

Thus, the understanding of the various mechanisms of action of estrogen and SERMs is an important medical challenge and could help to develop an “ideal” SERM, preserving the beneficial effects of estrogen in the bone and urogenital system, and reducing the unwanted side effects, mainly increased ris

Otherwise, ES ornidazole express high level of histone lysine specific demethylase 1 (LSD1) expression. In this context, it is proposed that LSD1 inhibition may block the function of EWS-ETS proteins [70]. Furthermore, checkpoint kinase 1 (CHK1), a modulator of cell survival under the condition of

A particularly important system in which Eph-ephrin signaling has been widely studied is neural development, in which downstream signal transduction controls neural stem cell (NSC) proliferation, migration, and survival both during early development and in adulthood (19, 20, 21). Furthermore, Eph-ep
