Antitumoral Efficacy of AuNRs‐Laden ECFCs In Vitro and In Vivo: Decoding the Heat and Rays Combo Treatment in Breast Cancer and Melanoma Cells

open access: yesAdvanced Healthcare Materials, EarlyView.
Endothelial Colony Forming Cells (ECFCs) acted as cellular cyborgs, stealthily transporting gold nanorods (AuNRs) into tumors to enable targeted near‐infrared (NIR) hyperthermia combined with radiotherapy. This approach triggers ferroptosis in melanoma and inhibits autophagy in breast cancer, revealing a tumor‐specific response to nanomaterial‐assisted

The functional differentiation of the post-PKS tailoring oxygenases contributed to the chemical diversities of atypical angucyclines

open access: yesSynthetic and Systems Biotechnology, 2018
Angucyclines are one of the largest families of aromatic polyketides with various chemical structures and bioactivities. Decades of studies have made it easy for us to depict the picture of their early biosynthetic pathways.

Tertiary alcohol preferred: Hydroxylation of trans-3-methyl-L-proline with proline hydroxylases

open access: yesBeilstein Journal of Organic Chemistry, 2011
The enzymatic synthesis of tertiary alcohols by the stereospecific oxidation of tertiary alkyl centers is a most-straightforward but challenging approach, since these positions are sterically hindered.

First Record of \u3ci\u3eAphis Helianthi\u3c/i\u3e (Homoptera: Aphididae) as a Pest of Celery [PDF]

open access: yes, 2017
In 1989, the aphid Aphis helianthi severely damaged five of 10 scouted celery fields in west central Michigan. In 1990 and in 1991, A. helianthi again was a problem. reaching pestiferous levels in three of 10 and two of 10 scouted fields.

Understanding miR‐200c: an Important Player in Resistance to Cancer Treatment

open access: yesAdvanced Therapeutics, EarlyView.
How can one microRNA alter cancer's response to therapy? miR‐200c plays a central role in therapeutic resistance by modulating epithelial‐mesenchymal transition, apoptosis, cancer stemness features, and drug efflux. This review outlines the context‐dependent functions of miR‐200c in various cancers and highlights its potential as both a biomarker and a

Loss of NR2F6 Protects from Salmonella Typhimurium Infection

open access: yesAdvanced Science, EarlyView.
Loss of nuclear receptor NR2F6 reduces tissue‐resident macrophage populations. Nr2f6‐deficient mice are protected from weight loss and bacterial load during infection with Salmonella Typhimurium. Pro‐inflammatory cytokines and iron levels are altered in infected Nr2f6‐deficient mice.

Oxidative modification of free-standing amino acids by Fe(II)/αKG-dependent oxygenases

open access: yesEngineering Microbiology, 2023
Fe(II)/α-ketoglutarate (αKG)-dependent oxygenases catalyze the oxidative modification of various molecules, from DNA, RNA, and proteins to primary and secondary metabolites.

Protective Effects of Inducible HO-1 on Oxygen Toxicity in Rat Brain Endothelial Microvessel Cells [PDF]

open access: yesEndocrinology and Metabolism, 2014
BackgroundReperfusion in ischemia is believed to generate cytotoxic oxidative stress, which mediates reperfusion injury. These stress conditions can initiate lipid peroxidation and damage to proteins, as well as promote DNA strand breaks.

ALKBH8-mediated formation of a novel diastereomeric pair of wobble nucleosides in mammalian tRNA [PDF]

open access: yes, 2011
Mammals have nine different homologues (ALKBH1–9) of the Escherichia coli DNA repair demethylase AlkB. ALKBH2 is a genuine DNA repair enzyme, but the in vivo function of the other ALKBH proteins has remained elusive.

Elevated Histone Lactylation Mediates Ferroptosis Resistance in Endometriosis Through the METTL3‐Regulated HIF1A/HMOX1 Signaling Pathway

open access: yesAdvanced Science, EarlyView.
This study reveals that histone lactylation, a modification derived from lactate, plays a crucial role in ferroptosis resistance in ectopic endometrial stromal cells. This resistance is mediated via the HIF1A/HMOX1 pathway regulated by METTL3. In vivo, a combination of 2‐DG and erastin shows promise as an effective treatment for endometriosis ...
