Escape from TGF‐β‐induced senescence promotes aggressive hallmarks in epithelial hepatocellular carcinoma cells

open access: yesMolecular Oncology, EarlyView.
Chronic TGF‐β exposure drives epithelial HCC cells from a senescent state to a TGF‐β resistant mesenchymal phenotype. This transition is characterized by the loss of Smad3‐mediated signaling, escape from senescence, enhanced invasiveness and metastatic potential, and upregulation of key resistance modulators such as MARK1 and GRM8, ultimately promoting

Extreme morphologies of mantis shrimp larvae [PDF]

open access: yes, 2016
Larvae of stomatopods (mantis shrimps) are generally categorized into four larval types: antizoea, pseudozoea (both representing early larval stages), alima and erichthus (the latter two representing later larval stages).

Super‐Tough Silk: The Potential of Knots in Evolved Spiders

open access: yesAdvanced Functional Materials, EarlyView.
The toughness of spider silk can be further significantly enhanced if spiders evolved the –currently absent/undiscovered– ability to tie knots in their silk. The results on 393 spiders suggest toughness increments by one or two orders of magnitude and thus a new perspective on how knotting can serve as a key innovation in spider evolution and in ...

A Bio‐Inspired Perspective on Materials Sustainability

open access: yesAdvanced Materials, EarlyView.
This perspective discusses natural materials as inspiration for sustainable engineering designs and the processing of materials. First, circularity, longevity, parsimony, and activity are presented as essential material paradigms. The perspective then uses many examples of natural and technical materials to introduce principles such as oligo ...

Functional Biomaterials Derived from Protein Liquid–Liquid Phase Separation and Liquid‐to‐Solid Transition

open access: yesAdvanced Materials, EarlyView.
Protein can undergo liquid–liquid phase separation and liquid‐to‐solid transition to form liquid condensates and solid aggregates. These phase transitions can be influenced by post‐translational modifications, mutations, and various environmental factors.
