Integrated computational approach identifies potential inhibitors of ASK1-(JNK/P38) interaction signaling: new insights into cancer therapeutics.

Cancers are characterized by the aberrant expression of certain genes that trigger a cascade of molecular events that culminate in dysregulated cell division. Consequently, the inhibition of the products of these expressedgenes has emerged as a rational approach in cancer therapy. The apoptosis signal-regulating kinase 1 (ASK1) protein, encoded by the mitogen-activated protein kinase kinase kinase 5 (MAP3K5) gene, plays pertinent roles in the mediation of cell death induced by stress and inflammation, andis often found at elevated levels in cancer.

Computational evaluation of bioactive compounds from (mistletoe) as inhibitors of p63 for pancreatic cancer treatment.

Pancreatic ductal adenocarcinoma is an aggressive malignancy usually detectable at the advanced stage, with a 5-year survival rate of less than 8%. It has been reported that a gene called tumor-protein 63 (TP63) is expressed in an aggressive form of pancreatic cancer with a squamous signature. Thus, inhibiting the activity of p63 can be a means of treating and managing PDA.

Computational Evaluation of Azadirachta indica-Derived Bioactive Compounds as Potential Inhibitors of NLRP3 in the Treatment of Alzheimer's Disease.

Background: The development of therapeutic agents against Alzheimer's disease (AD) has stalled recently. Drug candidates targeting amyloid-β (Aβ) deposition have often failed clinical trials at different stages, prompting the search for novel targets for AD therapy. The NLRP3 inflammasome is an integral part of innate immunity, contributing to neuroinflammation and AD pathophysiology.

Checkpoints and immunity in cancers: Role of GNG12.

Cancer progression is enhanced through cell proliferation, with the crucial role of the transducer and transmembrane -signal regulator (GNG12) bringing it to the fore. Dysregulation of cancer cell metabolism, evasion of the immune system, cell cycle, apoptosis, and chemoresistance result from inconsistent initiation of the NF-kB signaling pathway. We excerpt from previous studies that overactivation of the canonic NF-kB cascade occurs in varieties of tumor cells, which results in the growth of lymphovascular invasion, as well as neural invasion.
