A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

FEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Age and diabetes related changes of the retinal capillaries: an ultrastructural and immunohistochemical study [PDF]

, 2015
Normal human aging and diabetes are associated with a gradual decrease of cerebral flow in the brain with changes in vascular architecture. Thickening of the capillary basement membrane and microvascular fibrosis are evident in the central nervous system

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.

Small molecule-mediated tribbles homolog 3 promotes bone formation induced by bone morphogenetic protein-2. [PDF]

, 2017
Although bone morphogenetic protein-2 (BMP2) has demonstrated extraordinary potential in bone formation, its clinical applications require supraphysiological milligram-level doses that increase postoperative inflammation and inappropriate adipogenesis ...

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.

Anti‐inflammation – just another word for anti‐ageing?

The Journal of Physiology, 2009
Sarcopenia, the Greek term for ‘poverty of flesh’, refers to age-associated loss of muscle mass and strength. The cost of ageing is a potential unmanageable burden for society and ageing-related diseases remain a major challenge to the national healthcare systems.

Molecular Mechanisms of Anti-inflammation and Anti-cancer by 6-(Methylsulfinyl) hexyl Isothiocyanate [PDF]

, 2008
近年、世界的な健康ブームの中、野菜や果物の摂取と健康状態の関係が注目されている。疫学的調査や動物実験などを基盤とした研究結果により、ブロッコリー、カリフラワー、キャベツ、ワサビなどのアブラナ科植物の積極的な摂取は癌のリスクを低減させることが報告されている。そのため、これらアブラナ科植物は「癌の化学予防」の戦略から注目されている。６-（methylsulfinyl）hexyl isothiocyanate（６-MITC）はワサビに含まれる主要 allyl isothiocyanate である。いくつかの ...

Differential Effects of Lipid-lowering Drugs in Modulating Morphology of Cholesterol Particles. [PDF]

, 2017
Treatment of dyslipidemia patients with lipid-lowering drugs leads to a significant reduction in low-density lipoproteins (LDL) level and a low to moderate level of increase in high-density lipoprotein (HDL) cholesterol in plasma.

Transcriptional network analysis of PTEN‐protein‐deficient prostate tumors reveals robust stromal reprogramming and signs of senescent paracrine communication

Molecular Oncology, EarlyView.
Combining PTEN protein assessment and transcriptomic profiling of prostate tumors, we uncovered a network enriched in senescence and extracellular matrix (ECM) programs associated with PTEN loss and conserved in a mouse model. We show that PTEN‐deficient cells trigger paracrine remodeling of the surrounding stroma and this information could help ...
