Blood mitochondrial metabolism predicts flight performance without lasting effects of early-life thyroid hormones

iScience
Summary: Early-life conditions can shape adult phenotypes by influencing processes linked to energetic homeostasis. Thyroid hormones (THs) enhance mitochondrial electron transport chain capacity (ETS) in fledglings, but whether this effect is permanent ...

Peroxidasin enables melanoma immune escape by inhibiting natural killer cell cytotoxicity

Molecular Oncology, EarlyView.
Peroxidasin (PXDN) is secreted by melanoma cells and binds the NK cell receptor NKG2D, thereby suppressing NK cell activation and cytotoxicity. PXDN depletion restores NKG2D signaling and enables effective NK cell–mediated melanoma killing. These findings identify PXDN as a previously unrecognized immune evasion factor and a potential target to improve

Dammarenediol II enhances etoposide‐induced apoptosis by targeting O‐GlcNAc transferase and Akt/GSK3β/mTOR signaling in liver cancer

Molecular Oncology, EarlyView.
Etoposide induces DNA damage, activating p53‐dependent apoptosis via caspase‐3/7, which cleaves PARP1. Dammarenediol II enhances this apoptotic pathway by suppressing O‐GlcNAc transferase activity, further decreasing O‐GlcNAcylation. The reduction in O‐GlcNAc levels boosts p53‐driven apoptosis and influences the Akt/GSK3β/mTOR signaling pathway ...

Commensal human gut microbes produce species specific neuroactive compounds

iScience
Summary: The gut microbiota communicates with multiple organs through neuroactive molecules, but the specific compounds produced remain unclear. We investigated eight commensal gut species, Lactococcus lactis, Enterococcus faecalis, Blautia producta ...

TRAIL‐PEG‐Apt‐PLGA nanosystem as an aptamer‐targeted drug delivery system potential for triple‐negative breast cancer therapy using in vivo mouse model

Molecular Oncology, EarlyView.
Aptamers are used both therapeutically and as targeting agents in cancer treatment. We developed an aptamer‐targeted PLGA–TRAIL nanosystem that exhibited superior therapeutic efficacy in NOD/SCID breast cancer models. This nanosystem represents a novel biotechnological drug candidate for suppressing resistance development in breast cancer.

Creation's Persistent Voice: Critiquing the Secondary Status [PDF]

, 2012
Christianity struggles with the concept that nature/creation is truly revelatory of God, and not merely confirmatory of theological conclusions derived from special revelation or deduced from rational reflection.
