Structure, function, and mechanism of the TNFAIP8 (TIPE) family of proteins in cancer and inflammation

The multiple roles of the tumor necrosis factor(TNF)-α-inducible protein 8(TNFAIP8),also named TIPE family of proteins have been shown in tumor and inflammation progression and regulation of cellular autophagy and apoptosis.In this review,we found that the TIPE family showed highly homologous sequences and conserved functional domains,such as the death effector domain(DED)-like domain but displayed different roles and mechanisms in different biological activities.For example,while TIPE is primarily associated with tumor progression and antitumor drug resistance,TIPE1 suppresses tumor progression in most instances.TIPE2 has multiple roles in tumor progression regulation,and antitumor drug resistance.Moreover,TIPE2 was also involved in inflammatory response regulation,tumor typing,and staging.A few studies reported that TIPE3 was engaged in tumor development by activating the phosphatidylinositol-3-kinase(PI3K)/protein kinase B(AKT)signaling pathway.The structure,function,and mechanism of the TIPE family in cancer and inflammation have been summarized in this review.This might serve as a reference for further research on the TIPE family and shed new light on the crosstalk among antitumor responses,inflammation,and immunology.

Nanocellulose-based reusable liquid metal printed electronics fabricated by evaporation-induced transfer printing

Reusable electronics have received widespread attention and are urgently needed. Here, nanocellulosebased liquid metal(NC-LM) printed circuit has been fabricated by the evaporation-induced transfer printing technology. In this way, the liquid metal pattern is embedded into the nanocellulose membrane, which is beneficial for the stability of the circuit during use. Besides, the NC-LM circuit is ultrathin with just tens of microns. In particular, the finished product is environmentally friendly because it can be completely dissolved by water, and both the liquid metal ink and the nanocellulose membrane can be easily recollected and reused, thereby reducing waste and pollution to the environment. Several examples of flexible circuits have been designed to evaluate their performance. The mechanism of evaporation-induced transfer printing technology involves the deposition, aggregation, and coverage tightly of the nanosized cellulose fibrils as the water evaporated. This study provides an economical and environmentally friendly way for the fabrication of renewable flexible electronics.
