Two FAM134B isoforms differentially regulate ER dynamics during myogenesis.

Endoplasmic reticulum (ER) plasticity and ER-phagy are intertwined processes essential for maintaining ER dynamics. We investigated the interplay between two isoforms of the ER-phagy receptor FAM134B in regulating ER remodeling in differentiating myoblasts. During myogenesis, the canonical FAM134B1 is degraded, while its isoform FAM134B2 is transcriptionally upregulated.

Synthesis and assessment of gold nanoparticles conjugated with extracts, sterols and pure compounds derived from marine sponges from the Indian and Pacific Oceans.

Gold nanoparticles (AuNPs) exhibit different physical properties compared to small molecules, bulk materials and other nanoparticles. Their synthesis using plant extracts, particularly polyflavonoids as phytoreductants, for the conversion of Au(iii) into Au(0) has been reported. In this study, AuNPs were synthesized with extracts, sterols and pure compounds derived from marine sponges using gold(iii) chloride trihydrate.

Sestrin2 drives ER-phagy in response to protein misfolding.

Protein biogenesis within the endoplasmic reticulum (ER) is crucial for organismal function. Errors during protein folding necessitate the removal of faulty products. ER-associated protein degradation and ER-phagy target misfolded proteins for proteasomal and lysosomal degradation.

Application of Natural Functional Additives for Improving Bioactivity and Structure of Biopolymer-Based Films for Food Packaging: A Review.

The global trend towards conscious consumption plays an important role in consumer preferences regarding both the composition and quality of food and packaging materials, including sustainable ones. The development of biodegradable active packaging materials could reduce both the negative impact on the environment due to a decrease in the use of oil-based plastics and the amount of synthetic preservatives. This review discusses relevant functional additives for improving the bioactivity of biopolymer-based films.
