Abstract
The disadvantages of mainstream therapies for endometrial injury are difficult to resolve, herein, we suggest an omnibearing improvement strategy by introducing an injectable multifunctional self-assembled dual-crosslinked sodium alginate/recombinant collagen hydrogel. The hydrogel possessed a reversible and dynamic double network based on dynamic covalent bonds and ionic interactions, which also contributed to excellent capability in viscosity and injectability. Moreover, it was also biodegradable with a suitable speed, giving off active ingredients during the degradation process and eventually disappearing completely. In vitro tests exhibited that the hydrogel was biocompatible and able to enhance endometrial stromal cells viability. These features synergistically promoted cell multiplication and maintenance of endometrial hormone homeostasis, which accelerated endometrial matrix regeneration and structural reconstruction after severe injury in vivo. Furthermore, we explored the interrelation between the hydrogel characteristics, endometrial structure, and postoperative uterine recovery, which would benefit deep research on regulation of uterine repair mechanism and optimization of hydrogel materials. The injectable hydrogel could achieve favourable therapeutic efficacy without the need of exogenous hormones or cells, which would be of clinical value in endometrium regeneration.

Abstract
Materials science and genetic engineering have joined forces over the last three decades in the development of so-called protein-based polymers. These are proteins, typically with repetitive amino acid sequences, that have such physical properties that they can be used as functional materials. Well-known natural examples are collagen, silk, and elastin, but also artificial sequences have been devised. These proteins can be produced in a suitable host via recombinant DNA technology, and it is this inherent control over monomer sequence and molecular size that renders this class of polymers of particular interest to the fields of nanomaterials and biomedical research. Traditionally, Escherichia coli has been the main workhorse for the production of these polymers, but the methylotrophic yeast Pichia pastoris is finding increased use in view of the often high yields and potential bioprocessing benefits. We here provide an overview of protein-based polymers produced in P. pastoris. We summarize their physicochemical properties, briefly note possible applications, and detail their biosynthesis. Some challenges that may be faced when using P. pastoris for polymer production are identified: (i) low yields and poor process control in shake flask cultures; i.e., the need for bioreactors, (ii) proteolytic degradation, and (iii) self-assembly in vivo. Strategies to overcome these challenges are discussed, which we anticipate will be of interest also to readers involved in protein expression in P. pastoris in general.

Abstract
![]()
We
study the self-assembly of genetically engineered protein-based
triblock copolymers consisting of a central pH-responsive silk-like
middle block (SHn, where SH is a silk-like octapeptide, (GA)3GH and n is the number of repeats) flanked by hydrophilic random
coil outer blocks (C2). Our previous work has already shown
that triblocks with very long midblocks (n = 48)
self-assemble into long, stiff protein filaments at pH values where
the middle blocks are uncharged. Here we investigate the self-assembly
behavior of the triblock copolymers for a range of midblock lengths,
n = 8, 16, 24, 48. Upon charge neutralization of SHn by adjusting the pH, we find that C2SH8C2 and C2SH16C2 form spherical micelles, whereas both C2SH24C2 and C2SH48C2 form protein filaments with a characteristic
beta-roll secondary structure of the silk midblocks. Hydrogels formed
by C2SH48C2 are much stronger
and form much faster than those formed by C2SH24C2. Enzymatic digestion of much of the hydrophilic
outer blocks is used to show that with much of the hydrophilic outer
blocks removed, all silk-midblocks are capable of self-assembling
into stiff protein filaments. In that case, reduction of the steric
repulsion by the hydrophilic outer blocks also leads to extensive
fiber bundling. Our results highlight the opposing roles of the hydrophilic
outer blocks and central silk-like midblocks in driving protein filament
formation. They provide crucial information for future designs of
triblock protein-based polymers that form stiff filaments with controlled
bundling, that could mimick properties of collagen in the extracellular
matrix.

Abstract
Protein tags of various sizes and shapes catalyze progress in biosciences. Well-folded tags can serve to solubilize proteins. Small, unfolded, peptide-like tags have become invaluable tools for protein purification as well as protein-protein interaction studies. Intrinsically Disordered Proteins (IDPs), which lack unique 3D structures, received exponentially increasing attention during the last decade. Recently, large ID tags have been developed to solubilize proteins and to engineer the pharmacological properties of protein and peptide pharmaceuticals. Here, we contrast the complementary benefits and applications of both folded and ID tags based on predictions of ID. Less structure often means more function in a shorter tag.
