Structural biology of ferritin nanocages
FEBS Letters, EarlyView.Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Study on External Manufacturer Entering Strategy in Dual-channel Supply Chain [PDF]
, 2016 随着经济全球化的快速发展，企业间的竞争由供应链内部逐渐延伸到供应链外部。链外企业的进入威胁引起了国内外许多学者的关注，并进行了一系列的研究，但是这些研究主要是建立在单渠道供应链的基础之上，加之网络直销渠道的广泛运用，因此有必要在双渠道背景下研究链外企业进入行为。基于这些，本论文在双渠道供应链的背景下，研究外来制造商的进入方式对在位供应链成员的影响，并且从不同成员视角考察外来进入策略和在位阻止策略。 首先，考虑当外来制造商分别从传统渠道和直销渠道进入市场时，构建模型求解得到供应链各成员的最优反应函数 ...

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation
FEBS Letters, EarlyView.Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

The ubiquitin ligase RNF115 is required for the clearance of damaged lysosomes
FEBS Letters, EarlyView.Upon lysosomal rupture, an E3 ubiquitin ligase RNF115 translocates from the cytosol to the damaged lysosomal membrane. Moreover, RNF115 depletion impairs the clearance of damaged lysosomes, identifying it as a key regulator of lysosomal quality control.
