Nuclear prothymosin α inhibits epithelial‐mesenchymal transition (EMT) in lung cancer by increasing Smad7 acetylation and competing with Smad2 for binding to SNAI1, TWIST1, and ZEB1 promoters. In early‐stage cancer, ProT suppresses TGF‐β‐induced EMT, while its loss in the nucleus in late‐stage cancer leads to enhanced EMT and poor prognosis.

Configuration Interaction of Hydropathic Waves Enables Ubiquitin Functionality [PDF]
Ubiquitin, discovered less than 50 years ago, tags thousands of diseased proteins for destruction. It is small (only 76 amino acids), and is found unchanged in mammals, birds, fish and even worms. Key features of its functionality are identified here using critical point thermodynamic scaling theory.

LZTR1 is a regulator of RAS ubiquitination and signaling
Regulation of RAS by ubiquitination The protein LZTR1 is mutated in human cancers and developmental diseases. Work from two groups now converges to implicate the protein in regulating signaling by the small guanosine triphosphatase RAS.

USP22 controls necroptosis by regulating receptor‐interacting protein kinase 3 ubiquitination
Dynamic control of ubiquitination by deubiquitinating enzymes is essential for almost all biological processes. Ubiquitin‐specific peptidase 22 (USP22) is part of the SAGA complex and catalyzes the removal of mono‐ubiquitination from histones H2A and H2B,

RBR E3 ubiquitin ligases: new structures, new insights, new questions [PDF]
The RBR (RING-BetweenRING-RING) or TRIAD [two RING fingers and a DRIL (double RING finger linked)] E3 ubiquitin ligases comprise a group of 12 complex multidomain enzymes.

Long non‐coding RNAs (lncRNAs) occupy an abundant fraction of the eukaryotic transcriptome and an emerging area in cancer research. Regulation by lncRNAs is based on their subcellular localization in HNSCC. This cartoon shows the various functions of lncRNAs in HNSCC discussed in this review.

Proteins in a shear flow [PDF]
The conformational dynamics of a single protein molecule in a shear flow is investigated using Brownian dynamics simulations. A structure-based coarse grained model of a protein is used. We consider two proteins, ubiquitin and integrin, and find that at moderate shear rates they unfold through a sequence of metastable states - a pattern which is ...

The role of circular RNAs in regulating cytokine signaling in cancer
Cytokines present in the tumor microenvironment fuel cancer development. Aberrant expression of circRNAs contributes to cancer progression. Cytokines are involved in regulating circRNA biogenesis. Furthermore, aberrantly expressed circRNAs regulate the expression of ligands, receptors, and downstream effectors involved in cytokine signaling to promote ...

A mathematical model of p62-ubiquitin aggregates in autophagy [PDF]
Aggregation of ubiquitinated cargo by oligomers of the protein p62 is an important preparatory step in cellular autophagy. In this work a mathematical model for the dynamics of these heterogeneous aggregates in the form of a system of ordinary differential equations is derived and analyzed. Three different parameter regimes are identified, where either
